What glue can stick to the car rain shield, what glue to use for the car weather shield

Automobile shock absorbers are pasted with butyl glue.

Butyl rubber is a type of synthetic rubber that is synthesized from isobutylene and a small amount of isoprene. The finished product is not easy to leak, and is generally used to make inner tubes for the wheels of automobiles and airplanes. Butyl rubber is a copolymer of isobutylene and isoprene, which was put into industrial production in 1943.

Butyl rubber: butyl

rubber

Butyl rubber, or IIR for short, is an isobutylene isoprene

Abbreviation for rubber. It has good chemical and thermal stability, and the most prominent is air tightness and water tightness. Its air permeability is only 1 7 of natural rubber, 1 5 of styrene-butadiene rubber, and its permeability to steam is 1 200 of natural rubber and 1 140 of styrene-butadiene rubber.

Therefore, it is mainly used to manufacture various rubber products such as inner tubes, steam pipes, water tires, dam bottom layers and gaskets.

In 1943, the American Esso Chemical Company was the first to achieve industrial production. Since then, Canada, France, the Soviet Union and other countries have also realized the industrial production of butyl rubber. In the early 80s, the world's butyl rubber production capacity was about 650kt, accounting for about 5% of the total production of synthetic rubber.

Since the realization of industrial production of butyl rubber, the raw material route, production process and the structure of the polymerization kettle have not changed much, generally using methyl chloride as a diluent, aluminum trichloride as a catalyst, controlling the amount of these two can adjust the conversion rate of monomer. According to the grade requirements of the unsaturation of the product, the dosage of isoprene is generally the dosage of isobutylene, and the conversion rate is .

60%～90%。The polymerization temperature is maintained at -100 °C (ethylene and propylene are used as coolants). The polymerization of butyl rubber is carried out by positive ion reaction, the reaction temperature is low, the speed is fast, the exothermic concentration is concentrated, and the molecular weight of the polymer decreases sharply with the increase of temperature.

Therefore, the rapid discharge of the heat of polymerization to control the reaction at a constant low temperature is a major issue in production. The polymerization kettle (see figure) uses a tubular reactor with a large heat transfer area and a central conduit. During operation, the lower stirrer rotates at high speed to increase the amount of internal circulation, so as to ensure that the temperature of each point in the kettle is uniform.

Remove it with 3M double-sided tape (it must be real).

To glue 3M, first clean the wax on the paint surface, and then use 3M glue.

There are several classifications of 3M glue:

1. According to the characteristics, it is divided into double-sided tape and single-sided tape.

2. According to the substrate, the non-woven substrate double-sided tape is composed of non-woven substrate double-sided coated acrylic glue. Double-sided adhesive without substrate, directly coated with acrylic adhesive.

PET substrate double-sided adhesive is composed of PET substrate coated acrylic adhesive on both sides. Foam substrate double-sided tape, which consists of foam substrate ridge double-sided coated acrylic glue. Hot melt adhesive film, high temperature resistant tape.

The suitable environmental requirements for the storage of 3M double-sided tape are a temperature of 19 degrees Celsius to 23 degrees Celsius and a humidity of 40 to 60 percent.

As one of the world's top 500 companies, 3M has been rated as one of the 20 most innovative companies in the world for many years, and has been selected as one of the "Most Admired Foreign-Invested Enterprises in China" by Fortune for two consecutive years. In 2006, 3M was again named one of the 20 Most Admired Companies in the World by Fortune magazine.

Glass glue can stick to the glass. Glass glue is a material that bonds and seals various glass with other substrates, and is mainly divided into two categories: silicone glue and polyurethane glue (PU).

Silicone glue sealant - is what we usually call glass glue, and is divided into two kinds of acidic and neutral glue (neutral glue is divided into: stone sealant, mildew sealant, fireproof sealant, pipe sealant, etc.).

Summary. Extended information: You can use quick-drying glue, soft PVC glue and high-concentration PVC glue, which can stick to PVC very well.

Quick-drying glue can be used for bonding in a small area, and attention needs to be paid to air circulation; Soft PVC glue can bond PVC and other materials in a large area, and it takes 24 hours to cure; High-concentration PVC glue is generally used for bonding transparent PVC materials. If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. If you feel that my answer is still satisfactory, you can click on my avatar for one-on-one consultation.

Finally, I wish you good health and a good mood!

What glue to buy for a canopy.

Dear, hello and glad to buy your question what glue to stick to the canopy: the canopy beats weather-resistant silicone sealant, it is resistant to acid and alkali corrosion in the air, the sealing is better, and the performance of coping with temperature changes will be better. However, there are also glass glue, and there is no problem, and the performance is not as good as the weather-resistant silicone sealant.

If the glue is not played well, it is likely to leak from the glue seam when it rains for a long time.
