Contrast curing agent floor and cement floor different

Ground curing agent refers to the ground after the use of cement on the ground curing agent. It can be seen that the performance of the curing agent floor is significantly better than that of the ordinary cement floor. So what is the difference between curing agent ground and ordinary cement ground? 1, with a certain decorative performance. The cement floor after the construction of cement floor curing agent after grinding machine grinding can show a high gloss effect, and in the back of the use of the process, each friction is equivalent to grinding, curing agent floor highlights will be more and more bright. 2. Better physical properties. Cement ground curing agent can seal and solidify the pores inside and on the surface of the cement ground, so that it supports a dense whole, so that the floor in the hardness, strength, wear resistance, compressive ability and other properties have been greatly improved, do not have to worry about the ground is easy to dust from the sand. 3, easy to clean. Ordinary cement floor does not have a good sealing, if the ground is contaminated with oil, dirt, then these oil and other substances will easily penetrate into the interior of the floor, the formation of stains on the floor surface, it is difficult to clean up, affecting the overall perception of the floor. After the cement floor curing agent is constructed for the cement floor, the cement floor becomes a whole, and the impermeability is improved. Oil will not easily enter the cement floor. After the curing agent is contaminated with oil, timely treatment can leave almost no stain marks on the ground surface. 4. Long service life. Curing agent floor because of the hardness, strength, wear resistance, can withstand higher frequency and greater weight of vehicles, equipment, goods rolling and will not easily dust from sand, cracking, so the service life compared to ordinary cement floor is a great improvement. Under normal circumstances, the service life of the curing agent floor can reach more than 30 years. Although the performance of cement ground is mediocre, but with cement ground curing agent, it is the top type of the ground. The performance of the curing agent floor makes it popular and widely used in factory workshops, underground garages, logistics warehouses, open squares and other places.

What problems should be paid attention to when using the trowel?

If you want to make good use of the polishing machine, you must understand the blade, its quality is directly related to the effect of concrete polishing. Spreading machine spatula often use friction with the concrete surface, after a period of time will inevitably produce wear, so the general use of a period of time to replace the blade. When we choose, we must first look at the material of the blade. If the material is too soft, it will easily deform during use, which will cause unevenness. So we must choose those materials with high rigidity. And to choose those materials wear-resistant blades, because the friction of concrete is large, if the blade is not wear-resistant, it will cause the blade to be damaged if it is not used for a long time. It is also necessary to ensure that the size of the blade is basically the same, and the balance must be maintained when rotating. Scrub machine operation matters needing attention: 1. Before use, check whether the motor, electrical switch, cable and wiring are normal and meet the requirements, and install the leakage protector. 2. Check and clean up the debris on the smearing tray before use to avoid the whole machine beating during use. 3. After the power is turned on, the test run shall be carried out. The blades shall rotate clockwise and shall not be reversed. 4, the operator should wear insulating shoes, wear insulating gloves, cable by the auxiliary personnel, auxiliary personnel should also wear insulating shoes and wear insulating gloves. Take care to prevent electric shock caused by the insulation of the cable. 5. If the polishing machine fails, it must be shut down and cut off the power supply before maintenance. 6. The finishing machine should be stored in a dry, clean and non-corrosive gas environment, the handle should be placed in the specified position, and rough loading and unloading should not be allowed during transfer. No matter what kind of finishing machine, we must pay attention to these operational matters, to ensure construction safety, reduce unnecessary wear and tear. The construction speed is faster and the operation is more convenient. The important thing is that the ground effect is more uniform, smooth and beautiful.

How to make the floor grinding machine to achieve the ideal process?

How to make the floor grinding machine to achieve the ideal process? guangzhou qingqin yu environmental protection for you to answer! Meitengqi floor grinding machine is a kind of mechanical equipment capable of precision grinding and polishing, so some workpieces can be processed and polished, and the flatness after being processed is relatively high so far, but its process is more complicated and cannot be achieved in one step. It requires multiple steps and multiple links to achieve more ideal results. So how should we be on the floor grinding machine safe and reasonable operation, to be able to achieve a more ideal processing technology? In fact, the key to the operation is to find ways to get the maximum polishing rate, in order to be able to remove the damage layer produced when polishing as soon as possible. At the same time, the polishing damage layer must not affect the final observation of the organization, that is, will not cause some false tissue. The former requires the use of some relatively coarse abrasives to ensure a large enough polishing rate to remove the polished damage layer, but the polishing damage layer is also relatively deep. The latter requires the use of some finer than the material, so that the polished damage layer to achieve more shallow, but the polishing rate will be very low. The operation of the Meitengqi floor grinding machine is relatively simple, and the operator only needs to place the objects that need to be polished in advance. When starting the mechanical equipment, it is necessary to complete the polishing work within the set time and then stop automatically. Before polishing, it is necessary to carefully adjust the distance between the polishing head and the working surface to achieve the best contact effect and throwing effect. In the process of polishing, you can also use manual waxing, so as to reduce the production cost of the machine. For more information, please visit the website: http://www.qingqinyu.com/

New Journey Horn, China's New Development, New Opportunities for the World

New Journey Horn, China's New Development, New Opportunities for the World "Now, the CIIE has become a window for China to build a new development pattern, a platform to promote high-level openness, and a globally shared international public product." On November 4, President Xi Jinping delivered a speech at the opening ceremony of the Fifth China International Import Expo and pointed out that China's new development will continue to provide new opportunities for the world and promote the construction of an open world economy. The Fifth International Fair is the first major international exhibition held in China after the 20th National Congress of the Communist Party of China. A set of figures confirm the power of China's opening up-more than 280 of the world's top 500 and industry leading enterprises participated in the Fifth Expo, with a "return rate" of nearly 90%; the world's four major grain merchants, ten major medical device enterprises and fifteen major pharmaceutical enterprises have all arrived; a series of "world first show", "Asia first" and "China first exhibition" have appeared. Not long ago, when a member of the Standing Committee of the Political Bureau of the 20th CPC Central Committee met with Chinese and foreign journalists, General Secretary Xi Jinping stressed, "China's door to opening up will only get bigger and bigger. We will unswervingly deepen reform and opening up in an all-round way, unswervingly promote high-quality development, and create more opportunities for the world with our own development." China's development cannot be separated from the world, and the world's development also needs China. The vigorous movement of "China's new development, new opportunities for the world" is playing. "We must use openness to alleviate the difficulties of development, use openness to pool the power of cooperation, use openness to gather innovation, and use openness to seek shared blessings, so as to promote the continuous advancement of economic globalization, enhance the development momentum of all countries, and make development results more More equitable to benefit the people of all countries." At the opening ceremony of the Fifth China International Import Expo, President Xi Jinping spoke sonorously. China has a population of more than 1.4 billion and middle-income groups above 0.4 billion. It imports about 2.5 trillion US dollars of goods and services every year, and the market scale is huge. The market is an important resource, and the market of large countries is a global scarce resource. From 9 square meters to 108 square meters to 200 square meters, from 0.38 billion yuan to 0.7 billion yuan to 1 billion yuan, the exhibition area of American essential oil company Dotley at the Expo has increased year by year, and the amount of purchase intention signed has increased year by year. McOwen, the relevant person in charge of dotley, could not hide his excitement. "Since participating in the Expo, dotley has developed at a high speed and grown together with the Expo." △ On November 5, visitors experienced the application of "Yuan Universe" in the artificial intelligence zone of the 5th Expo. With the deepening of high-quality development, the "magnetic force" of the Chinese market is more powerful. "In recent years, China has accelerated its digital transformation and upgrading, which has led to the integration and development of new technologies. The great achievements in 5G, artificial intelligence, electric transportation, industrial Internet, intelligent manufacturing and other fields are obvious to all." Kang Liang, general manager of ABB (China) Co., Ltd., said that China has released new huge market potential and opportunities in the process of promoting high-quality development, and will continue to attract multinational companies to continue to expand investment and layout in China. In August this year, Honeywell, a Fortune 500 company, and Honeywell, a Chinese power battery company, joined hands with Honeycomb Energy, to build a Honeycomb Energy digital factory by integrating product and technological advantages to achieve lean and automated industrial transformation and upgrading. "As a'old friend' of the CIIE, we will rely on the open and efficient platform effect of the CIIE to continuously introduce leading innovations into China and promote local innovation to the world." Honeywell company related responsible person said. General Secretary Xi Jinping pointed out in the report of the 20th National Congress of the Communist Party of China that relying on my country's ultra-large-scale market advantages, attracting global resource elements with a large domestic cycle, enhancing the linkage effect of two resources in the domestic and international markets, and improving the quality and level of trade and investment cooperation. "The Chinese market is crucial" has become an international consensus. China's sincerity in taking the initiative to open its market to the world and sharing China's opportunities with other countries is injecting strong positive energy into the difficult recovery of the world economy. In the welcome hall of the National Convention and Exhibition Center (Shanghai), the huge Chinese painting "Spring Breeze and Green River South Bank" conveys a clear message to the world with poetic Chinese elements: let the open spring breeze warm the world. On November 4, President Xi Jinping emphasized at the opening ceremony of the Fifth China International Import Expo that China will promote all countries to share institutional opening opportunities. On the 4th, when President Xi Jinping met with German Chancellor Scholz at the Great Hall of the People in Beijing, he pointed out: "China will unswervingly promote high-level opening up, adhere to the correct direction of economic globalization, continue to promote the construction of an open world economy, and expand The point of convergence of the interests of all countries." The promise of a big country, a promise of a thousand dollars. The opening commitment of the previous four CIIE sessions is reflected in the "Special Administrative Measures for Foreign Investment Access (Negative List)": in 2019, the requirement that domestic shipping agencies, cinemas construction and operation, and performance brokerage agencies must be controlled by the Chinese side will be canceled; In 2020, the requirement that the Chinese share ratio of automobile manufacturing enterprises (except special vehicles and new energy vehicles) shall not be less than 50% will be canceled in 2021, cancellation of securities, funds, futures, life insurance and other financial companies foreign shares ratio of not more than 51% and other restrictions. Milk produced on Monday at a foreign ranch can be on the plane on Tuesday and directly to the table of Chinese consumers on Wednesday ...... As one of the first pilot enterprises of the innovative regulatory model of "inspection and release" separation and "border inspection and release" for trade facilitation, Roy, Global R & D General Manager of New Zealand's Newland Dairy, really felt the charm of "speed of entry. "This shows China's firm attitude to continuously optimize the business environment through determined reforms, innovative systems, and improved processes." Over the past decade, China's institutional openness in rules, regulations, management and standards has been deepened. From the launch of the first negative list of foreign investment access in the pilot free trade zone in 2013, to the launch of the first negative list of cross-border service trade in Hainan in 2021, and then to the revision of the "Catalogue of Industries Encouraging Foreign Investment" many times, China is relaxing The level of institutional openness has been continuously improved by "subtraction" in market access and "addition" in preferential policies. △ On October 15, the Marshall Islands "Arab Diher" freighter, carrying Spanish exhibits of the Fifth Expo, berthed at the fourth phase of Yangshan Deepwater Port. Experts believe that institutional opening is based on the opening of regulations, rules, and standards. It has comprehensive, systematic, and stable characteristics. It is a higher-level and higher-level opening. "Steadily expanding institutional openness in rules, regulations, management and standards", "promoting the building of a new type of international relations and deepening the expansion of a global partnership of equality, openness and cooperation", "firmly pursuing a mutually beneficial and win-win strategy of openness" ...... The word "openness" has appeared many times in the report of the Party's 20th National Congress, and "China's door to opening up will only get bigger and bigger" has brought warmth to the world economy. On the new journey, China with surging development momentum and China with warm spring breeze will surely provide new development opportunities for the world. One minute, what can happen? The China-Europe train transported 3 TEUs of goods, 30 passengers and 7 TEUs of goods arrived at the destination through the Monnet Railway, the Karot Hydropower Station in Pakistan, which was built with the assistance of Chinese enterprises, generated electricity to meet the electricity needs of 5 million local people, and the total import and export volume between China and the countries along the "Belt and Road" reached 25.3 million yuan ...... Not long ago, this set of "one minute" data on social media, vividly presents the story of China's promotion of economic globalization. △ On November 5, visitors watched the robot performance in the artificial intelligence area of the 5th Expo.

The number of participating countries along the "the belt and road initiative" and SCO countries also increased compared with the previous one. Nicaragua, Djibouti, Mauritania, Comoros, Mozambique, Congo (DRC), Iraq and Iceland participated in the national exhibition for the first time. The Karot Hydropower Project, the first hydropower investment project in the China-Pakistan Economic Corridor, will provide clean and cheap electricity to Pakistan and promote its green development. The report of the 20th National Congress of the Communist Party of China stated: "China adheres to the correct direction of economic globalization, promotes trade and investment liberalization and facilitation, promotes bilateral, regional and multilateral cooperation, promotes international macroeconomic policy coordination, and jointly creates an international environment conducive to development. Jointly cultivate new drivers of global development". Some comments pointed out that China has always placed its own development in the coordinate system of human development, allowing countries to take the express train and free ride of China's development, and promote the world economy to a better tomorrow. The aroma of Tanzanian sesame, nutritious Kenyan avocado, meat sweet juicy South African citrus ...... According to Shanghai Customs statistics, from January to August this year, a total of 4.72 billion yuan of African agricultural products have been imported from the Shanghai port. From Africa to Latin America, with the special products of many countries entering the Chinese market, the lives of local people are more hopeful-"orders from China have made the villagers rich" and "cooperation with China has made us have a better life". "China's development and the world's development are mutually integrated and mutually successful." China's new development is providing new opportunities for the world. East Timor is located in the Nusa Tenggara Islands in Southeast Asia, where the soil and climate conditions are suitable for the growth of coffee trees. In recent years, East Timor coffee has become a "net red" product in China. Due to the increase in orders from China, local coffee growers are busy and their income has increased. The road is at your feet and the light is ahead. China, which does not stop reforming and opening up, will create new and greater miracles that will impress the world. China on the new journey will share a bright future with the world!

How to use floor grinding machine to do a good job in the floor paint before construction

To ensure and improve the adhesion of the floor paint coating: the treated concrete base surface can make the floor paint primer more penetrate into the concrete surface, which plays a key role in the service life of the whole floor paint coating. Especially when there is oil and water on the base surface, it is difficult to form a continuous coating due to the poor compatibility of oil and water with the coating. Even if a complete coating is formed, the coating adhesion will be greatly reduced, causing the coating to fall off prematurely. When the surface of the dust is not directly through the base surface care construction, the light causes the floor paint coating to produce pitting, heavy may lead to a large area of floor paint coating off, shorten the service life of floor paint. Therefore, at the same time to establish a smooth, smooth, beautiful coating to make the necessary preparations for the entire floor paint project to create a good foundation. Create the right surface roughness: floor paint coating attached to the concrete surface is mainly rely on the polar molecules in the floor paint and the mutual attraction between the surface molecules of the substrate. Concrete after floor grinding machine grinding treatment, will make the surface rough, with the increase of roughness, surface area increased significantly, the unit area of the coating and the base surface of the gravity also doubled, but also for the floor paint coating attachment provides a suitable surface shape, increase the mechanical tooth cooperation, the epoxy floor paint coating attachment is very favorable.
