What are the materials of door and window sealing strips:
1. Rubber and plastic materials:
Rubber is a kind of PVC, the processing equipment in brief, and investment in less, the material is very easy, the colour of the finished product, also can recover, using rate is very high, so all the capital in low, rubber with plastic, and even with blunt nose smell, its flexibility, patience and a bad weather in stretching the future reply slowly, And it's highly affected by temperature.
2, EPDM EPDM:
Epdm has the very good ozone resistance and oxidation resistance, good heat resistance and low temperature characteristics and so on many merits, the other, but also has good electricity, mutatis mutandis, the sex and outstanding stress-strain characteristics and so on merits, out of goods but also in safe, and dimensional accuracy is very high, but the epdm color comparison list one by one, since a self-adhesive stick with each function is poor.
3, covering type sealing rubber strip:
The sealing strip function is very well, and is energy-saving, environmental protection international three generations of seal products, by the strength of the thermosetting core and outer cortex and not of the same material system, to ensure the sealing strip long time use in different environment and cause of deflation and deformation, the strip has significantly, mutatis mutandis, the effect of sound insulation noise reduction and very superior heat preservation and heat insulation.
4, plastic steel doors and Windows sealing rubber strip:
Above is a brief introduction about what are the doors and Windows sealing strip material, believe that through the above introduction, you will have further knowledge of doors and Windows sealing strip material and understanding, and of course selection at the end of the doors and Windows sealing strip, the next step is to be installed, what what are the precautions for sealing strip prior to installation of the window? Take a look at the following introduction:
Precautions before installation of window seals:
1, before the installation of glass to carefully remove debris in the notch, such as mortar, brick debris, wood, etc., the glass should be carefully placed in the center, to ensure that the clearance on both sides of the uniform, and timely more positive fixed, prevent collision displacement, deviation from the notch center.
2, rubber seal can not be pulled too tight, cutting length than assembly length 2O-3OMM, installation should be embedded in place, the surface is straight, and glass, glass notch close contact, so that the glass surrounding force uniform, in the corner rubber strip should be bevel disconnected, and in the disconnect glue bonding firm.
3. When sealant is used to fix the glass, the glass should be squeezed with rubber strip or rubber block first, and the glue injection gap should be set aside. The glue injection depth should be no less than 5mm.
4, the installation part of the wool is generally in the window (door) fan, box fan around or seal bridge (block), enhance the seal between the box and the fan.
5, the specification of the wool is an important factor affecting the sliding doors and Windows and watertight performance, is also an important factor affecting the doors and Windows switch force, the wool specification is too large or vertical hair is too high, not only difficult assembly, but also make the doors and Windows movement resistance increases, especially when opening the initial resistance and closing the final resistance in place is larger.
6, the specification is too small, or the vertical wool height is not enough, easy to come out of the groove, the sealing performance of doors and Windows greatly reduce the table picture, the wool needs to be siliconized, the quality of the appearance of the wool for the surface is straight, the bottom plate and the vertical wool is smooth, no bending, no hemp on the bottom plate, in line with the provisions of 0.2mm.
