PolyurethaneFoamingGlue is a kind of glue that is mainly used for the side seams of building doors and windows and the expansion and contraction of components. Filling, sealing and bonding of seams and holes. It is a polyurethane elastic sealing foam material that relies on moisture to cure. It is a one-component, moisture-cured, multi-purpose polyurethane foam-filled elastic sealing material. Foam rubber is a special polyurethane product that contains polyurethane prepolymer, foaming agent, catalyst and other components packed into a pressure-resistant aerosol can.
High-quality foamAfter curing, it has various effects such as caulking, bonding, sealing, heat insulation, and sound absorption. It is an environmentally friendly, energy-saving, and easy-to-use building material that can be used for sealing, sealing, gap filling, and fixing. Bonding, thermal insulation and sound insulation, especially suitable for sealing, plugging and waterproofing between plastic steel or aluminum alloy doors, windows and walls.
Foam rubber products have clear industry standards for testing. Judging the quality of foam rubber can also look at many aspects, such as shrinkage and expansion rate. So, today the editor of Weigu will take you to understand, What hidden dangers will the shrinkage and expansion of foam rubber bring to doors and windows?
What is shrinkage? Styrofoam shrinkage means that the beaten styrofoam will shrink after curing. So what hidden dangers will styrofoam shrinkage bring to doors and windows? Generally, some low-priced and low-quality foam rubber products on the market will shrink. The shrinkage of foam rubber will cause problems such as weak doors and windows, deformation, etc. It will also lead to problems such as reduced sound insulation, water leakage in doors and windows, and unsealed gaps in doors and windows. Therefore, the shrinkage of foam glue brings huge hidden dangers to the houses we live in every day. We must choose high-quality foam glue to use.
Pre-foaming is foaming glue spray After it comes out, 80%has been foamed, and the foaming range in the back is very small, so that workers can better control the strength of their hands when using foam glue, which is simple and convenient And no glue is wasted, which greatly saves costs. If the post-expansion coefficient of the styrofoam is too large, it may cause the doors and windows to deform and break, making it more troublesome to clean up later. Therefore, for the installation of wooden doors, it is recommended to use front-foaming foam glue and do not use foam glue with a high rear expansion coefficient for construction.
