Sealing tape molding equipment (sealing tape on windshield)

Introduction: In daily life, when we install doors and windows, there are always certain gaps that cause the door and window department to tightly close. The function of door and window sealing strips is to eliminate these gaps. But there are many types of door and window sealing strips, and their purposes are also different. Here, I have compiled some relevant information on the types of door and window sealing strips for everyone.

1. Steel skeleton with three composite components, not easy to deform and shrink, firmly assembled, and with good sealing performance

2. The sealing strip molding equipment for doors, windows, and curtain walls (sealing strip on the windshield) has good elasticity, migration resistance, and can effectively block noise, dust, and wind and rain. Since 2009, especially in the second half of the year, major automobile sealing strip enterprises have clearly felt a serious lack of production capacity, and have participated in the expansion of production capacity, activating automobile sealing strip equipment manufacturing enterprises, With a large number of equipment orders in hand, I feel the difficulty and importance of delivery time.

Its outstanding advantages are: ① its performance and service life are equivalent to that of vulcanized EPDM rubber; ② its processing energy consumption is relatively low compared to vulcanized EPDM rubber strips (equivalent to PVC); ③ it does not contain heavy metals such as halogens and lead, and can be recycled after several years, meeting the requirements of green building materials. The ash in it is white, and the silicone rubber is still white after friction on white paper; The ash content is black, and the rubber that turns black after rubbing on white paper is EPDM or chloroprene rubber; The ash content is black, and natural rubber has a sticky feel when touched by hand at the extinguished area.

3. Door and window sealing strips can be divided into three categories in terms of usage: glass sealing strips, door leaf and door cover sealing strips, and wool strips. The glass sealing strip is used to seal the gap between the glass leaf and the frame. The door leaf sealing strip is used to seal the gap between the door panel and the frame, while the wool strip is mainly used to seal the gap between the frame and the frame. In the installation process of various doors and windows, sealing strips are indispensable.

Sealing strips play a sealing and waterproof role in plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. The sealing strip has high requirements for material. First, it must have strong tensile capacity and elasticity, as well as good temperature resistance and aging resistance. At the same time, in order to ensure close contact between the sealing strip and the profile, the cross-sectional structure of the sealing strip must match the door and window profile, and is generally suitable for hanging windows and folding doors and windows.

4. How to see the sealing strength of doors and windows for the sealant strip forming equipment (the sealant strip above the windshield)? 1. Look at the door and window sealant. Use the anti-aging and elastic sealant between the window sash glasses. Touch it with your hand. It is soft and resilient, and it is not easy to fall off. Check whether the information material provided by it meets the physical performance indicators specified in the standard. The outside is a watertight chamber, and the inside is a gas tight chamber, forming an isobaric chamber, The pressure inside the isobaric chamber is equal to the pressure outside, preventing rainwater from entering the room. According to the siphon principle, rainwater flows out through its own gravity.

At present, the sealing strip market generally consists of modified PVC, vulcanized and thermoplastic EPDM/PP rubber strips. The classification and characteristics of door and window sealing strips, vulcanized EPDM sealing strips, vulcanized EPDM rubber sealing strips: in terms of sealing elasticity and durability, they are stronger than PVC strips. However, due to the need for microwave vulcanization line shaping, the processing energy consumption is high, usually more than 20 times that of PVC processing, and the product cannot be reused and is not environmentally friendly, Not the product we advocate for.

Wool strips are generally used to install on the leaves of push type doors and windows, to seal the gaps between frames and leaves. The specifications of wool strips can greatly affect the water tightness of doors and windows, and also affect the opening and closing of doors and windows. If the specification of the wool strip is too large or the vertical hair is too high, it will be very difficult to assemble, and after assembly, it will also cause the resistance of the doors and windows to increase when they move. If the fire specification is too small or the vertical hair is too low, the doors and windows are prone to bracket phenomenon, reducing the sealing of the doors and windows. There are generally two types of wool tops: those that have undergone silicification treatment and those that have not undergone silicification treatment. Generally, the use effect of treated wool tops is better. Qualified wool strips have the following characteristics: no obvious defects in appearance, flat surface, smooth bottom plate and vertical hair, no bending phenomenon, and no pits or other problems on the bottom plate, meeting the size specifications.
