What is polyurethane resin and its application? Epoxy floor coatings were first created by Germany in the 1930s. After more than 80 years of development, epoxy floor with its excellent wear resistance, chemical erosion resistance and other functions can be the most ordinary use, both dress up as a building, building style is guaranteed. At the same time, the development of the contemporary industry has put forward more and more stringent requirements on the floor, such as multi-layer production room, chemical raw material pipeline pumping and so on. Solvent free polyurethane self leveling Pingchuan Ping raw material.
More and more, the two-component solvent-free polyurethane self-leveling in raw material functions, such as crack bridging function, the use of temperature boundaries, impact resistance, yellowing resistance, wear resistance, chemical corrosion resistance test results, may wish to fill the existing epoxy floor there are some shortcomings, and the construction method is similar to the epoxy floor. Ping represents the trend of the development of floor technology.
Over the years, the common shortcomings of epoxy floor have to be summarized in the following aspects.
As the basic structure of the concrete, the surface of the epoxy resin is a thermosetting resin with high mechanical strength but poor elasticity. Therefore, the filling of the cracks in the concrete is limited, resulting in reflective cracks on the epoxy floor.
In the production area, warehouses and other areas where goods are required to be handled, because of the turnover of goods, forklift trucks, equipment transfer, etc., the epoxy floor surface is simply scraped, more and more car tire marks.
Dropping of goods and equipment onto the ground is a common phenomenon in the production process. Epoxy floors are used in such working conditions, resulting in pits and scattering.
Ultraviolet rays in sunlight can destroy the molecular chains of epoxy resins. Long-term exposure to ultraviolet light can cause decolorization/yellowing of epoxy floors.
