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. Sparing machine spatula is often used with the concrete surface friction, 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. Sour 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 wiping 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 the transfer should not be rough loading and unloading. No matter what kind of smoothing machine, we must pay attention to these operational matters, to ensure construction safety, reduce unnecessary loss. 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.

Floor coatings for a breakthrough in adversity

Now the domestic paint industry polarization serious. On the one hand, large brands have great influence, high customer loyalty, strong profitability, and strong accumulation of resources. On the other hand, small and medium-sized paint brands can only use their small scale and low cost to fight price wars. Using the thin and bullish strategy, they occupy a lot of shares in the paint market, but these paints often face quality problems. Under the inspection of the industrial and commercial departments, they often survive for a short time. Global paint prices are rising. With the improvement of people's living standards, green consumption has become the mainstream consumption concept. Only when paint companies work hard on the environmental performance of their products can they win more consumers. "Green" and "low carbon" are the key words in the research and development of paint enterprises. want to know more about the information of paint, can at any time to inquire guangzhou qing qinyu environmental protection science and technology limited company http://www.qingqinyu.com/product/36/

The construction site will no longer be dusty, and new equipment will be added for road maintenance.

It's not just polishing work. In fact, if we go to the construction site, we will find that a lot of work is hard and dirty. But at the same time, these dirty and tiring jobs are also essential to our modern life. We have no way not to do these jobs, but what we can do is to try to use some modern tools and equipment to reduce people's workload and improve people's working environment as much as possible. Polishing itself is in a very dirty environment, because if we want to polish on the wall or the ground, it will inevitably splash a lot of dust, so that the whole working environment is very bad. But we have also been trying to improve this harsh working environment, and Meichen's dust-free road grinder is one of them. Dust-free grinding machine can be said that we are designed for the reality of dusty grinding work environment. Since the emergence of the grinding machine, it can be said that our human workload has been reduced a lot, but even if we use the grinding machine, the working environment has not changed, to a certain extent, it can be said to be even worse. Because the grinding machine tends to make more dust splash. It comes with a high-power vacuum cleaner, so in the work, the dust has not spread, it has been sucked into the vacuum cleaner, so that the natural working environment will be improved. It can be said that dust-free polishing has brought us more health.

Working principle of milling machine

Pavement milling machine is one of the main types of asphalt pavement maintenance and construction machinery. One of the main equipment for asphalt concrete pavement maintenance and construction is mainly used for the excavation and renovation of asphalt concrete surface layers such as highways, urban roads, airports, freight yards, etc. It can also be used to remove defects such as pavement embossment, oil waves, mesh patterns, rutting, etc. It can also be used to excavate potholes and grooves on the pavement, and milling of cement pavement. Milling the damaged old pavement with a road milling machine, and then laying a new surface layer is one of the most economical modern maintenance methods. Because of its high efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good mobility, milling of old materials can be directly recycled, etc., it is widely used in urban municipal roads and highway maintenance projects. Main structure and working principle The general milling machine is composed of engine, frame, milling rotor, milling depth adjustment device, hydraulic components, aggregate conveying device, steering system and braking system. The milling rotor is the main working part of the milling machine. It is composed of the milling rotor shaft, the cutter seat and the cutter head. It directly contacts with the road and achieves the purpose of milling through its high-speed rotating milling cutter. The milling machine is equipped with an automatic leveling device, which uses the side cover of the milling rotor as the milling reference surface and controls two positioning hydraulic cylinders to keep the given milling depth constant; Its hydraulic system is used to drive the milling rotor to rotate, the whole machine to walk, auxiliary device work, etc. It is generally a closed hydraulic system with multiple pumps independent of each other, which does not interfere with each other and has high reliability when working. Some milling machines are equipped with inclination adjusters as required to control the inclination of the rotor. Generally, large milling machines have an aggregate conveying device composed of a conveyor belt and a collector, which can concentrate and transfer the milled bulk material to a random walking vehicle. The height of the conveying arm can be adjusted and can swing left and right to adjust the unloading position. When the specifications and models of the milling machine are different, their structure and layout are slightly different, but the basic working principle is the same or similar. The route of power transmission of milling machine: engine → hydraulic pump → hydraulic motor, hydraulic cylinder → working device.

Problems of Highway Maintenance Machinery

Problems of Highway Maintenance Machinery After years of large-scale construction, China's highway network has been basically formed, is about to enter a high tide of highway maintenance and repair. At the same time, the increasingly heavy traffic pressure puts forward higher requirements for the efficiency and quality of highway maintenance. These favorable factors will promote the development of highway maintenance machinery, and the concept of long-term "reconstruction and light maintenance" has led to the backward level of highway maintenance mechanization in China, so the future development space is huge and the market prospect is broad. Although the road maintenance machinery industry has made great progress, but the existing problems are also prominent, especially in the era of road maintenance, and the contradiction between the market demand is increasing. Specifically, the road maintenance machinery industry mainly has the following three major problems. 1, the industry foundation is weak, insufficient research and development. China's highway construction started late, the research on highway maintenance technology is not enough attention, most of the existing maintenance technology is introduced from abroad in recent years, therefore, the industry as a whole the original innovation ability is insufficient, advanced maintenance equipment is still mostly supplied by foreign manufacturers. 2. The industry has a high technical threshold, a long product promotion cycle, and the products also have the characteristics of multi-variety, small batch and customized production. Therefore, some large domestic construction machinery companies with research and development capabilities are currently unwilling to intervene. This also leads to the domestic enterprises engaged in the industry is generally small, research and development capacity and investment is insufficient, compared with similar foreign enterprises in product reliability and advanced there is still a gap, some of the technology and products in the country is still in the blank. 3, the industry standard system is not perfect. The standard system in the industry is not yet sound and perfect, and the basic standards that have a guiding role for the entire industry are still relatively scarce, which is not conducive to the rapid and healthy development of the industry.
