Unified national price for low-cost ultra-high molecular polyethylene resin lining emerging chemical, polymer resin liner on emerging chemical production, wear-resistant resin liner, cement repository resin liner, new cement repository liner factory new chemical, a variety of resin, curing agent, modifier system can adapt to almost the form of a variety of applications requirements, which can range from very low viscosity to high melting point solid. Two curing convenient. Selection of a variety of curing agents, epoxy resin system is almost in the temperature range of 0 ~ 180 ° C curing. 3, strong adhesion. Inherent polarity of the epoxy molecular chain hydroxyl and ether linkages of the existence of various substances with high adhesion. Epoxy curing shrinkage is low, the internal stress, which also help to improve the adhesion strength. 4, low shrinkage. The reaction of epoxy resin and curing agent is carried out by direct addition reaction or resin molecules in epoxy ring-opening polymerization, no water or other volatile by-product release. They are unsaturated polyester resins, phenolic resins compared to show low shrinkage (less than 2%) during the curing process. 5, the mechanical properties. The cured epoxy resin system with excellent mechanical properties. 
 Resin refers to molecules containing two or more epoxy groups of organic polymers, in addition to the individual outside of their relative molecular mass is not high. The molecular structure of the epoxy resin based on the molecular chain contains lively epoxy group is characterized by the epoxy group at the end of the molecular chain, in the middle or into a ring structure. Molecular structure contains a lively epoxy groups to enable them with various types of curing agent, the crosslinking reaction and the formation of insoluble, infusible polymers to the mesh structure.
