Polyurethane
foaming agent is a full-component one-component polyurethane foam sealant, commonly known as foaming agent, styrofoam, PU grouting agent. English PU FOAM is the product of cross-combination of aerosol technology and polyurethane foam technology. It is a special polyurethane product which is filled with a polyurethane prepolymer, a foaming agent, a catalyst and the like in a pressure resistant aerosol can. When the material is ejected from the aerosol can, the foamed polyurethane material rapidly expands and solidifies to react with the air or the moisture in the contacted matrix to form a foam. Wide range of applications. It has the advantages of front foaming, high expansion, small shrinkage, etc., and the foam has good strength and high adhesive strength. The foam after curing has various effects such as caulking, bonding, sealing, heat insulation and sound absorption. However, many people do not know the quality of the polyurethane foaming agent they purchased, so today's plastics industry website - Jiuzhi Plastics Network will tell you how to judge the quality of polyurethane foaming agent?
1. If it is a gun-type polyurethane foaming agent, the effect of the gun is seen. When foaming, the foam sprayed should be smooth, not too thin or too thick, too thin to foam, and collapsed, too thick to be foam. Dry hair, the foam is easy to shrink;
2, the polyurethane foaming agent on the newspaper, hit a layer, the next day to see whether the two ends of the foam is tilted, such as curl, bright foam shrinkage, the higher the warp, the more the shrinkage; From the beginning, the foam is good;
3, cut the foam, look at the cells, the cells are evenly fine and good foam, such as large cells, and the density is not good, it is a defective product;
4. Look at the foam surface of the polyurethane foaming agent. The surface of the good foam is grooved, smooth but the gloss is not very bright; the poor foam surface is flat and wrinkled;
5, look at the size of the polyurethane foaming agent foam, good foam foam full and round; poor foam foaming, and collapse;
6. Press the foam by hand, the foam is elastic, it is a good foam; the poor foam has no elasticity;
7, look at the adhesion of polyurethane foaming agent, good foam bonding strength, poor adhesion is poor.
Self-Priming Pump(CIP Pump)
Self-Priming Pump is a hygienic side-channel design sanitary pump, it is applicable by food processing, biopharm and chemical industries. Self-priming pump is specially designed for pumping materials what containing air or gas, and it can be also be used for negative suction with prior priming as well as with filtration equipment. Kaysen self-primping pump, Hygenic Self-Priming Pumps, Self-Priming Pumps, Cip Self-Priming Pump can be used for wine, fine oil, syrups, volatile products such as alcohol, acetone and other solvents, or other materials which temperature close to boiling point. However, the mainly using field of self-priming pump is for CIP returning.
