Pressure filter special sealing ring manufacturers bq8cx low temperature need not say more, the lower the temperature the stronger the elasticity. In general, high and low temperature silicone rubber seal can be used normally. Silicone rubber seals are made from environmentally friendly materials that do not emit smelly and toxic gases. That is to say epdm rubber seal strip, doors and Windows will usually be installed seal strip, so can be dustproof waterproof, sound proof seal. According to the different USES can be divided into door flap door cover seal strip, wool strip, glass seal strip (rubber strip) three categories. The door flap/cover seal is mainly used for sealing between the door panel and the door frame, but the apron can play a certain protective role.

Installation method of door and window sealing strip

1, the glass mat strip and stop strip window frames, window sashes should be in the welding clear Angle according to the correct direction of the strip with a special roller to push the strip a little force into the profile notch, while the sealing strip head to press down into the embedded profile notch. As the rubber strip is elastomer, after roller pressing, may appear retracement, the correct method is: when the sealing strip is installed to the joint at both ends, the two ends of the rubber strip to the middle retracement, and leave 2-3 cm contraction margin, and then cut into the slot.

2, the glass layering will seal the rubber strip according to the correct face with manual way of the rubber strip into the profile slot, and then forced by the appearance of the rubber strip, the rubber strip into the gap between the glass and the profile. Retract the two ends of the strip to the middle, leaving 1-2 cm length before cutting, press into the notch.

Precautions for door and window sealing strip installation

1. Before installing the glass, the debris in the notch should be carefully removed, such as mortar, brick chips, wood blocks, etc. When placing the glass, the center should be carefully aligned, the clearance on both sides should be even, and fixed in time to prevent collision and displacement, and deviation from the center of the notch.

2. The rubber seal shall not be stretched too tightly, and the cutting length shall be 20-30mm longer than the assembly length. When installation should be set in place, the surface is straight, and glass, glass notch close contact, so that the surrounding force uniform glass. In the corner of the rubber seal should be inclined to break, and at the break point of the adhesive bond firm.

3. When sealing the glass with sealant, the glass should be squeezed by rubber seal strip or rubber block first, leaving a gap for glue injection. The glue injection depth should be no less than 5mm.

4. The installation place of the wool sliver is generally on the window (door) fan, around the frame fan or on the sealing bridge (wind block) to enhance the sealing between the frame and the fan.

5. Wool sliver specification is an important factor affecting sliding door window and watertight performance, as well as an important factor affecting door and window switch force. Wool sliver specification is too big or bristle is too high, not only assemble difficulty, and make door window moves resistance to increase, especially when the initial resistance that opens and when close hind place resistance is bigger.

6, the specification is too small, or the height of vertical hair is not enough, easy to come out of the groove, so that the door and window seal performance is greatly reduced. About epdm silicone rubber seal strip, the wool sliver needs to undergo silicification treatment, the appearance of qualified wool sliver for the surface straight, bottom plate and vertical hair smooth, no bending, there is no hemp on the bottom plate, in accordance with the 0.2mm provisions.
