Ningxia waste curing agent recycling factory

The heat resistance of catalytic polymerization curing agent is generally at the level of aromatic polyamines. The heat resistance of anionic polymerization type (tertiary amine and imidazolized antiques) and cationic polymerization type (BF3 complex) are basically the same, which is mainly due to the fact that although the initial reaction mechanism is different, the network structure of ether bond binding is eventually formed.

Different range of products have different performance; High reactivity, rapid curing at room temperature or low temperature; Relatively insensitive to humidity. It has certain color stability; Good chemical corrosion resistance, especially solvent resistance; Good high temperature performance when used for thermal curing; Good chemical resistance and good electrical and mechanical properties.

What are the functions of curing agent
Hard: the Mohs hardness of the treated concrete floor will reach 8, increasing by about 200%;
Wear resistance: solidify various components in the concrete into hard and dense entities, and increase the wear resistance to about 6 times;
Friction: surface friction increased by 22.5%;
Dust prevention: chemical reaction occurs with silicate in concrete to form a compact whole and prevent surface dust;
Skid resistance: prevent salt and alkali components from precipitating from the surface, so as to prevent slippage and efflorescence of concrete surface;
Compression resistance: the treated sample is 40% stronger than the untreated sample, and the bending strength is more than twice as high;
Impermeability: it can effectively penetrate into the concrete to lock pores, and prevent water, oil and other dirt from penetrating into the concrete;
: Effectively prevent chloride ion and ultraviolet radiation, and concrete will not be affected by exposure to electromagnetic or water mist;
Corrosion resistance: the corrosion resistance of treated concrete floor is greatly improved;
Adhesion: the adhesion with epoxy resin is increased by 21.9%, and the adhesion with paint is basically unchanged;
Curing force: during the one day curing process of concrete, the water retention rate increases by 94.5% to prevent cracking;
Brightness: the treated concrete floor will have a marble like luster, and the longer you use it, the better the gloss;

Curing agent can be divided into room temperature curing agent and heating curing agent according to the use. Epoxy resin generally has good performance when cured at high temperature, but coatings and adhesives used in civil construction need to be cured at room temperature due to heating difficulties.

Therefore, aliphatic amines, aliphatic epoxides and polyamides are mostly used, especially the coatings and adhesives used in winter have to be used together with polyisocyanates, or polyisocyanates with foul smell are used. As for medium temperature curing agent and high temperature curing agent, the choice should be based on the heat resistance of the object to be landed and the heat resistance, adhesion and drug resistance of the cured object.
