Performance characteristics of immersion sealant: it can improve the overall performance of products such as condensate, stone, mortar and concrete; concrete surface hardness 33.3% and density, thereby reducing the damage of heavy machinery to the air; flexural strength, colouring strength and bonding strength of other materials. It can avoid the diffusion of various toxic gases; 50% to 90% of internal chlorides; the pollution of rust and water pollutants, thereby reducing maintenance costs; the growth of moss, moss and other organisms on the surface, thus eliminating the need for regular cleaning, which can prevent plastic from shrinking, cracking, curling, peeling and cracking, corrosion of internal rebar, alkaline weathering, acid rain or fouling. Immersion of dyes causes discoloration and metamorphosis of concrete, which can resist up to 98% of water and vapor pressure, various chlorides on expressways and seas, oil stains, gases, acidic substances, solvents, bacteria and ultraviolet rays, and exfoliation/expansion/spallation due to temperature variation.
The role of paint curing agent: It is understood that curing agent, also known as hardener, curing agent or stabilizer, is also a kind of material or mixture that promotes or controls the curing reaction. Resin curing is a process of irreversible change of thermosetting resin through chemical reactions such as condensation, closed-loop, addition or catalysis. Curing is accomplished by adding curing agent. Curing agents can be divided into room temperature curing agents and heating curing agents according to their uses. Epoxy resin has excellent general properties when cured at high temperature, but the coatings and adhesives used in civil buildings need room temperature curing, medium temperature curing agent and high temperature curing agent because of the difficulty of heating. They should be selected on the basis of the heat resistance of the implant and the heat resistance, adhesion and resistance of the cured material. The selection focuses on polyamines and anhydrides. Because anhydride cured products have excellent electrical properties, they are widely used in electronic and electrical fields. Aliphatic polyamine cured products have excellent adhesiveness, alkali resistance and water resistance. Aromatic polyamines are also excellent in drug resistance. Because the nitrogen element of amino group forms hydrogen bond with metal, it has excellent antirust effect. The higher the concentration of amine, the better the anti-rust effect. As long as these raw materials and technologies are accurately grasped and their quality is carefully controlled, high quality curing agents can be consumed.
