Description:
* The material used for the ML cooling tower filler is PVC/PP/ CPVC. The purpose of the filler is to increase the viscosity of the product, especially the small filler to increase the viscosity significantly. ML cooling tower fill before accumulation is subject to dehydration sale to avoid consuming some of the isocyanate. It must be noted that the changeable carbon anhydride will cause the resin to foam, which will deter the physical properties of the polyurethane resin.
* In order to speed up the wetting speed of ML cooling tower fill and reduce system viscosity. Still more and more fillers are increasing in the polyurethane resin, sometimes it is necessary to add a wetting and wetting dispersant in the resin in advance. In-mold paint is an additive with three benefits of coating, colorant and release agent.
* The ML cooling tower filler is evenly burst into the mold, and after the paint film is dried, the polyurethane sole, self-skin foam, and polyurethane soft foam can be molded. necessary products. If the envoy wants to say that the quality of the filling habits is determined, it still depends on the following aspects:
① ML cooling tower packing has a larger specific surface area (m2/m3 packing layer);
② ML cooling tower filler liquid has better mechanical properties of uniform distribution on the surface of the filler;
③ The packing airflow of ML cooling tower can be evenly distributed in the packing layer;
④ ML cooling tower packing material is not without large porosity (m3/m3 packing layer). There are other caves, and factors such as its doctrinal strength, origin, artificiality and price should also be considered when choosing fillers carefully.
