One function of the automatic door is to prevent the big air exchange between indoor and outdoor, and the sealing brush or sealing strip play a very important role to this purpose .

▪ Rubber and plastic materials.

Rubber and Plastic material is a kind of PVC, which is very popular to use as a sealing material, the processing equipment is easy to get and it need less investment which make them used more and more in automatic door field .

▪ EPDM.

EPDM possess the very good area resistance and oxidation resistance, good heat resistance and low temperature characteristics and lots of other merits, its dimensional accuracy is very high, and we could choose lots of different colors .

▪ Encapsulated sealing tape.

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.

▪ Sealing Strip for plastic steel doors.

Window of model steel door sealing strip is in recent years in terms of use in a wide range of new generation of doors, it is usually the doors sealing strip corrosion and weather resistance function is very good, and have the effect of the noise reduction thermal insulation, the appearance of this kind of steel door sealing strip is very light, has very good waterproof sealing function, and function of the house of beautiful decoration.

Above is a brief introduction about the sealing strip material, and I think that through the introduction above, you will have further knowledge of sealing strip material for doors, and the next step is about the installation, please check the part below for details.

1. To the doors, before installing the glass, carefully remove the debris in the slot, such as mortar, brick dust, wood, etc., when the glass is placed, it should be properly aligned to ensure the space on both sides is even, and be properly fixed in time to prevent collision and displacement and deviation from the center of the slot.

2. The rubber sealing strip cannot be stretched too tightly the blanking length is 20-30mm longer than the assembly length. When installing, it should be inlaid in place and the surface should be straight.

3. When using sealant to fill and fix glass, rubber strip or rubber block should be first used to squeeze the glass, leaving a space for cementing. The depth of cementing should be no less than 5mm.

4. The mounting part of the wool strip is generally on the door leaf, around the frame fan or on the sealing bridge (wind damper), and the sealing between the frame and the fan is enhanced.

5. The woolen bar specification is an important factor affecting the performance of sliding door and water tightness, as well as an important factor affecting the opening and closing force of doors .

6. If the specification is too small, or the vertical woolen strip is not high enough, it is easy to get out of the groove, so that the sealing performance of doors can be greatly reduced in the table picture.
