Types and properties of epoxy floor paint:

1, epoxy resin floor, epoxy self leveling floor, epoxy sand floor has good decorative properties; 2, epoxy anti-static floor has a good anti-static effect; 3, metal wear-resistant floor, emery wear-resistant floor has good wear resistance and so on. The user can choose the corresponding floor products according to the requirements of the ground: First: due to the different floor decoration performance characteristics, if the ground needs better decorative floor should choose self leveling floor, sand floor and so on; Second: according to the different materials of the floor to choose different types of floor coatings. For example, the building floor surface materials are concrete, cement, mortar, wood, steel, asbestos cement board, etc., different materials have different requirements for floor paint coatings, therefore, should be in accordance with the different materials of the base layer to choose different types of floor paint coatings; Third: according to the budget cost to choose floor paint. The budget price determines the level of floor paint, the more budget, of course, you can choose a better floor paint, performance is more secure. Fourth: in accordance with the next floor to decorate the length of time to choose floor paint. If the next floor decoration time interval is longer, to choose a better performance such as wear resistance floor paint, if the next time to decorate the time interval is relatively short, you can choose the performance of a little worse floor paint.

Epoxy floor paint shedding and processing methods

Reason: epoxy floor paint coating before the basic surface treatment is not good, coated on the surface of the basis of oil, wax, water vapor, dust and chemicals, or surface pretreatment to paint the construction interval is too long. Treatment: The surface of the coated object shall be treated and cleaned before coating, and the coating construction shall be carried out immediately. 2. Reason: Improper selection of primer. If the hardness of the primer is too large, the adhesion between the topcoat and the primer will be lost. Treatment: Primer with good adhesion and wettability should be selected. 3. Reason: The surface of the coated object is too smooth Treatment: The surface of the coated material should be polished or chemically treated. Old paint should be re-polished. 4, reason: in the primer is not dry before the finish or varnish, the film is prone to cracking or falling off. Treatment: Generally, the primer should be completely dried before finishing paint. 5. Reason: The coating film is too thick, because the surface layer has been dried out, while the bottom layer is dried slowly or not dried out. During the drying process, the topcoat shrinks too much and causes cracking and falling off. Treatment: construction should pay attention to each paint film should not be too thick.

Road and bridge equipment industry status

Highway construction and maintenance is an industry with high resource occupation, high energy consumption and high carbon emission, and is one of the key areas of national energy conservation and emission reduction. Every year, 30~4 billion t of sand and other materials are consumed, including 1 billion t of high-quality aggregate; For every 1t of hot-mixed asphalt mixture produced, 7~9kg of fuel oil is consumed, about 18kg of CO2 and a large amount of toxic and harmful gases such as asphalt smoke are emitted. In 2017, the actual use of asphalt mixture in China is about 0.45 billion t, and the mixing of asphalt mixture alone will consume about 3.6 million t of fuel oil and emit 26.48 million t of CO, which will seriously affect the construction of resource-saving and environment-friendly transportation industry. Green highway is the necessity of building a "resource-saving and environment-friendly" society. It is the integration of concepts such as "energy saving, emission reduction, recycling, and environmental protection" in highway construction. It requires strong support from technological innovation and institutional innovation. With the continuous development of large-scale highway construction and maintenance, the shortage of high-quality aggregates, the consumption of petroleum asphalt and the pollution during the construction process have gradually become prominent, especially in the fields of road material recycling, energy saving and emission reduction, and environmental protection. Some technical weaknesses. Facing the increasingly severe resource situation and environmental pressure, the recycling of waste materials is applied to the construction and maintenance of roads, turning waste into treasure, and forming an industrial chain in line with the circular economy model, which will lead the scientific development of the road engineering industry and meet the needs of "building a resource-saving and environment-friendly transportation industry.

The excellent performance of emery wear-resistant floor

Social progress is reflected in all aspects of life, such as the floor. Now the development of the floor can be said to be an indispensable thing in our lives. For many people, it is very difficult to walk on hard ground and then walk on muddy roads. With the development of the times, the change of the floor has also experienced many periods. At present, the emery wear-resistant floor is a popular type of floor. Emery wear-resistant floor has many excellent properties, which is the reason for its wide application. Due to the excellent performance of diamond wear-resistant floor, in life to avoid the floor moisture, moisture and many other issues, its excellent flatness, flatness and smoothness can also avoid local damp floor. And if ordinary concrete, we know that the humidity of concrete is indeed the most common picture, especially in summer, when the humid air with higher temperature (relative humidity greater than 90%) meets the ground with lower temperature, smooth, and non-absorbent, The condensation of water droplets does bring great inconvenience to life. Due to its compact structure, it is not easy to be penetrated by water and gas, and naturally avoids moisture. Due to its high hardness, the service life of the emery wear-resistant floor is very long, and the problem of using twenty or thirty years is really not big.
