Small, powerful glue bar As the necessary accessories for the door and window system, the cost of the sealing strip is only 1-3% of the door and window system, but its sealing effect is 50-70%. It can be said that the door and window are good, the key is the glue bar. Six main functions: waterproof, dustproof, sound insulation, temperature isolation, shock absorption, and anti-collision sealing strips installed on doors and windows, frames, fans and glass. According to the elastic properties of the doors and windows, the cracks between the sections of the door and the windows, the hardware and the glass are sealed, and they are tightly connected to a whole to improve the air tightness of the doors and windows. Water tightness, sound insulation and energy saving play an indispensable role. The heat loss of poorly sealed doors and windows is 5-6 times the heat loss of the wall. The thermal insulation and air tightness of doors and windows play an important role in energy conservation and consumption reduction in buildings.
Classification of adhesive strips According to the material, it is divided into three categories One is rubber plastic strip, that is, modified adhesive strip. Two is three ethylene propylene (EPDM) adhesive strip Three is silicone rubber (MVQ) adhesive strip Among them, three yuan ethylene propylene has become the mainstream of the market due to its excellent sealing and durability. Divided by shape and assembly position There are five kinds of aluminum alloy heat insulation broken bridges: glass, glass, isobaric, frame, flat, The plastic steel profiles are divided into three types: PO/PK/O strip
What is the high quality three yuan ethylene propylene rubber strip? Good elasticity, good quality and light luster Easy to assemble life long
The harm of using inferior glue strips Poor sealing, easy aging, dew and rain, affecting the beauty and life of doors and windows, bring personal life a lot of trouble. Oil leakage, odour, no environmental protection, incompatibility with plastic steel doors and windows, macular degeneration, reduced aesthetics.
How to distinguish the quality of the adhesive strip Smell - ----- should the nose be asked if there is any odor, the normal material has a little alcohol taste, very small, almost no smell, the inferior seal not only applies to the different quality of the waste, but also overdosage of the ingredients and low molecular weight of aromatic oil or complex oil refining oil deep fried oil as a substitute for plasticizer, this product When the factory has just gone out of the factory, it has a large odor. As time goes on, the component volatilized quickly. The sealing strip quickly becomes brittle and brittle. The adhesive strips shrink, loose, and fall off. It is very easy to crack aging and lose the sealing effect. See - ---- - - - - high quality adhesive strip surface smooth, light sense, no obvious impurities and other defects, uniform color, in summer when the sealant contact with the profile, the poor quality of oil or heavy oil migration of the profile yellowing, the presence of discoloration, yellowing oil, and high quality three ethylene propylene rubber strip is not good. This is the case. The quality of the adhesive strip is smooth, no saw tooth marks, no crack on the surface, delicate, soft, no distortion, no fluctuation. Poor quality products will feel rough to some extent, even crack. Pull - --- good adhesive strips are stretched without breaking, and can be restored quickly after bending. High fill seal strip strength is poor, ninety percent off split, a pull will be broken. Called - --- called weight, the same volume of sealant, high quality to clear, and vice versa, high quality three yuan ethylene propylene rubber strip with imported raw rubber, light weight, high anti aging degree. The products produced by reclaimed rubber are relatively large in proportion and poor in aging resistance. Test - ---- field inspection, insert the glue bar between the profile and glass, check the rationality of the section shape of the rubber strip and the suitability of the size and size, so that the pressure into the rubber strip is not very hard, and the greater the strength of the glass, the better.
