HC plastic mesh News: 80 years from the last century onwards, when the global manufacturing industry into large scale enterprises and Chinese technology, domestic flooring industry has undergone a great period of development, in terms of materials or construction techniques have made great progress . However, current situation of the industry in recent years, flooring industry, especially in the high-end market, mostly high-end market is still dominated by foreign brands, domestic enterprises in this field, there was little breakthrough, and there is mid-market and even low-end market also fell in crisis. The key to solve this problem first, the development of resin flooring materials breakthrough.

Developing world, especially the industrial flooring industry developed earlier, such as the United States, Japan and France has 67 years of history, product technology and engineering are quite mature. The current type of material generally as follows: First, epoxy resin: the first used as a floor of resin material, the most mature technology is much the largest species, mainly abroad, solvent-free system, a small water system to use, solvent- system very little material, most of the material has not produced solvent material. Second, acrylic acid (cross-linked) type of material, based on methyl acrylate monomer polymerization of unsaturated system; such material has excellent weather resistance, can be used for outdoor environment, and because its rapid cross-linking reaction greatly shorten the construction period, more can be better in curing temperature below zero, so the cooler can also be the construction environment.

Polyurethane flooring materials is another major materials, according to Chinese experts, industry associations epoxy, polyurethane epoxy material relatively late, so the manufacturing technology and construction techniques are relatively difficult to control, but recent because of its superior performance in increasing access to a wide range of applications. The properties of the polyurethane has broad scalability, there is another similar epoxy elastomer material hardness, resistance to organic acids and organic solvents is better than epoxy, epoxy more unmatched flexibility. In machinery manufacturing, Food Processing industries is widely used. Foreign materials as epoxy urethane floor as mainly a non-solvent system, a small water system.

And domestic resin flooring materials and international similar, use the same epoxy material to solvent-based epoxy, but the main floor is estimated that about 70% of the material, non-solvent system is relatively small, water-based system is less. Acid (cross-linked) type of material in domestic use less, in addition to the purpose of the vinyl material corrosion outside. Polyurethane materials are all essentially solvent-based systems, generally 30 to 40% with solvent. With Polyester And polyether polyurethane-based, mostly thin coating applied to floor, almost no solvent-free products and water products. These two types of solvent-based products accounted for the vast majority of domestic flooring material, in the early use of such materials abroad, mostly to cement the concept of sealant used, do not care about thickness. In the domestic flooring material coated invention concept, which coupled with some sort of fill sand flat layer thickness increased. However, much strength as compared with solvent-free discount.
