Door and Window Sealing Strip Tapes Epdm Door And Window Sealing Strip Epdm Rubber Strip
Product Description
Epdm Door And Window Sealing Strip (Epdm Door And Window Sealing Strip) is a sealing strip mainly used for plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows and other decorative doors and windows. The plastic steel door and window sealing strips on the market are generally extruded from PVC, modified PVC, EPDM, elastomer sealing strips (including TPV, TPE, TPR, SEBS), silicone and other materials.
Use of Epdm Sealing Strip
Epdm Window Seal is divided into three categories: glass sealing strip (adhesive strip), door leaf door cover sealing strip and wool strip. The glass sealing strip is used for the sealing between the glass and the door leaf and the frame. The door leaf and door cover sealing strip is mainly used for the sealing between the door panel and the door frame, and the top is mainly used for the sealing between the frame and the fan. In plastic steel doors and windows, broken bridges In the production and installation of aluminum doors, windows and wooden doors, Epdm Window Seal is an indispensable accessory.
Effect
Epdm Door And Window Sealing Strip plays an important role in waterproofing, sealing, and energy saving in plastic steel doors and windows, broken aluminum doors and windows, and wooden doors and windows. Epdm Window Seal is soundproof, dustproof, antifreeze and warm. It must have strong tensile strength, good elasticity, good temperature resistance and aging resistance. In order to ensure the fastening of the rubber strip and the profile, the cross-sectional structure size of the rubber strip must match the profile of the plastic steel door and window. Epdm Window Seal is generally used for casement doors and windows, hanging windows, and folding doors and windows. The main functions are dustproof, insectproof, waterproof, soundproof, and airtight.
The top installation position is generally on the sliding window (door) fan, around the frame fan, or on the sealing bridge (wind block) to strengthen the seal between the frame and the fan. The top specification is an important factor affecting the performance and water tightness of sliding doors and windows, as well as an important factor affecting the opening and closing force of doors and windows. Too large top or high vertical hairs will not only make assembly difficult, but also increase the resistance of doors and windows, especially the initial resistance when opening and the final resistance when closing. If the specifications are too small, or the height of the vertical roof is not enough, it is easy to fall out of the groove, greatly reducing the sealing performance of doors and windows.
Epdm Window Seal has two types of tops: siliconized and non-siliconized. The siliconized top is more effective in use. The qualified table surface is straight, the bottom plate and vertical hair are smooth, without bending, and the bottom plate has no pits, which meets the 0.2mm requirement.
Identification
The actual key to doors and windows is sealing, and the sealing strips play a pivotal role. The material of the sealing strips used in the market is generally modified by PVC. The key role in soft PVC is the quality of the plasticizer added to it. As the prices of various petrochemical products continue to rise, the sealing strips Prices of other rubber products are also rising.
Some irresponsible manufacturers only look at short-term benefits and start unfair competition from raw materials (so-called cutting corners, shoddy goods, using waste engine oil, oil base leftover from the refinery, etc.) to replace high-quality plasticizers. Consumers have brought great hidden dangers. In the door manufacturing process, the input of the sealing strip is very small, but its role cannot be ignored. The quality identification methods of the door and window sealing strip include the following:
1. The appearance of oil leakage on the surface appears. The waste engine oil is not compatible with PVC at all. Grease is easy to appear on the surface of the sealing strip, and yellow marks are also stained on the surface of the profile. Even if it is not environmentally friendly, there are many volatile substances that pollute the air.
2. When those so-called plasticizers volatilize or ooze out, the sealing strip will lose its original softness, become very hard, and quickly age and shrink, so that a large gap appears in the airtight part of the door and window, and the airtightness changes. Very bad (leakage, dust leakage), especially the steel lining inside plastic steel doors and windows will corrode quickly. Many users often find that a lot of red liquid flows out from the beading part of the windows in the rainy season and it is dirty, that is, the leaking steel lining of the doors and windows Corroded early, the life of doors and windows will be greatly reduced.
In the actual production process, the investment of the sealing strip accounts for a small proportion, but its role cannot be ignored. So there is no need to choose those counterfeit products in order to reduce the cost. The identification method is very simple.
First, use your nose to smell whether there is any peculiar smell. Normal PVC material will have a little bit of mellow smell, which is almost invisible.
Second, wrap the sealing strip on the profile as tightly as possible, and leave it at high temperature for a period of time (on the roof or in a sunny place). Check whether the surface of the profile and the contact surface of the sealing strip is stained or discolored, whether the dust on the surface of the sealing strip is yellow (the oil is easy to absorb soil), and whether the hands are dirty.
Third, some relatively cheap sealing strips will have a lot of fillers, so the surface will not be very shiny, and those that are cheap and not shiny are not desirable.
Fourth, look at the specific gravity, how many meters can be produced per kilogram. Many manufacturers have made great efforts in the use of fillers. In order to achieve greater output (saving a little electricity), they use talcum powder, heavy calcium and the like as fillers, which greatly increase the proportion of sealing strip products. (We Users generally buy by kilograms and use them by length) This invisibly increases the cost more than the loss. The sealing strip with heavy calcium added, stretched back and forth by hand several times, a small amount of white powder will appear on the surface.
Precautions
The glass is not installed in the center, the gap between the glass and the window frame is uneven, the rubber sealing strip is not close to the glass and the window frame, and the installation is uneven. Knock the glass with your hand, there is a loose sound. The reasons for this situation:
1. The sundries in the notch are not removed in time when the glass is installed, so that the glass is not aligned with the notch.
2. The gap between the glass and the glass notch is uneven, and the rubber strip is in poor contact with the glass and the glass groove, protruding from the glass notch, and the sealing strip can be easily pulled off by hand.
3. The rubber strip is not broken at the corners, and glue is not injected.
