Note Doors and Windows sealing this field has been for a long time, and then some views on the sealing of doors and Windows to share with you.

The key of doors and Windows is the sealing, and the sealing effect, the rubber strip plays a key role. Sealing rubber strips in building doors and Windows must have enough tensile strength, good elasticity, good temperature resistance and aging resistance, section structure size to be scientific and reasonable and perfect match with building doors and Windows profiles. Sealing rubber strip is used to seal between glass, fan and frame, and plays a decisive role in sound insulation, dust proof, frost proof, warm and so on.

Previously, the material of sealing rubber strip is generally modified by PVC. The key role is the plasticizer added inside. At present, the relatively stable plasticizer has dioctyl phosphophthalate and dibutyl ester, but the market price is higher. So some small manufacturers use something cheap instead.

These hidden dangers are manifested in: 1. Low sealing of doors and Windows. Poor quality sealing rubber strip containing inferior plasticizer or substitutes, easy to aging in winter, hardening, shrinkage. There is a gap between the glass and the profile, resulting in water leakage and dust. Many users often find that the red liquid flows out of the surface of the plastic window in the rainy season, which is caused by the corrosion of the steel lining caused by the water between the window glass and the sealing rubber strip. Not only greatly reduce the beauty of doors and Windows, but also greatly affect the life of doors and Windows. 2. Oil seepage occurs on the surface of the rubber strip. Waste oil and PVC are not at all and sealing rubber strip, the surface is easy to appear grease, yellow stains on the surface of the profile, not environmental protection, odor, pollution of the air.
