Production Process and Application of Silicone Sealing Strip

Silicone sealing strip is a commonly used product in the sealing strip industry. It is used for liquid/gas sealing of various large-scale chemical and daily necessities. It can completely isolate the contact between the carrier and the outside world and effectively preserve the goods. Silicone rubber sealing strip, its production process is divided into two kinds, different product size to choose different processing technology. Building doors and windows, large machinery this kind of sealing strip, size and design shape is very critical, so most of the use of extrusion process. However, some small electronic products and sealing strips usually choose the molding process.

How to distinguish the quality of your door and window sealing strip?

According to statistics, China's building energy consumption has accounted for 27.5 of the terminal energy consumption of the whole society, and the energy lost through the gaps around the closed doors and windows usually accounts for about 37-40% of the building energy consumption. Therefore, it is very important to improve the sealing performance between the sash and the glass, especially between the window frame and the window sash. Therefore, the door and window sealing strip determines the installation quality and performance of the door and window to a certain extent.

Product characteristics of EPDM sealing strip

The weather resistance of the product is very good. It can be used for a long time in the cold natural environment and the hot natural environment and the natural environment such as dry and humid air, and it can also have good corrosion resistance. These advantages can make the product The use period is longer. EPDM sealing strips have been tested several times before manufacturing. It can be seen from the experiments that the products can also work continuously in high temperature natural environment without aging. Therefore, many companies use the products to improve efficiency and gain more profits.

What are the production methods of silicone straw?

How are silicone straws made in the market? Silicone straw color is very beautiful, in the past should be introduced in cups, bottles and other aspects, now in many countries to launch the "ban on plastic law" determination and give up the background of plastic straw, silicone straw slowly become a popular product, many enterprises are using silicone straw, so how to make silicone straw? The principle of silicone straw extrusion is divided into raw material preparation, glue practice, extrusion, vulcanization, secondary vulcanization and back-end processing. These steps can be used for the finished product of food grade silicone straws. At present, the company uses platinum vulcanization technology to produce silicone straws, which are non-toxic to other raw materials, have no peculiar smell, have no harm to human contact, are environmentally friendly, and are easy to decompose and drain. There are 7*9,6*8,7*10,8*10,8*11 and so on. This is common in the market, except for molded silicone straws.

How to Distinguish Liquid Silicone and Solid Silicone Products

The liquid silicone product has high transparency, no peculiar smell, the product has a glue injection edge, no obvious mold lines and hair edge defects, and the appearance is relatively delicate and beautiful. The solid silicone product has low transparency, has the smell of curing agent or other curing agent, the product is not injected with glue, the mold is closed up and down, and the parting part of the product has a certain mold self-separation line. Liquid silica gel is a kind of food grade material with high transparency and high safety. It does not add curing agent and other auxiliary materials in the process of forming and sealing feeding. Solid silica gel is a transparent material, need to add curing agent to speed up the vulcanization molding time, open mold feeding molding.

Foamed silicone sealing strip is widely used and has excellent performance.

Foamed silicone sealing strip is widely used in automobile, aerospace, computer, mechanical and electrical industry, dust removal equipment, dust removal equipment, cement plant cover plate, mining equipment, door seal, fax machine, printer high temperature parts; automobile machinery body, kitchen appliances, household appliances and other equipment. The performance of the foamed silicone sealing strip is: good thermal stability. Excellent aging resistance-can be used for a long time at 130°C, and can also be used at intervals or for a short time at 150°C or higher. The weather resistance of foaming silicone sealing strip refers to the aging of light, heat, freezing, wind, rain, ozone and oxygen in the atmosphere in the natural environment. Chemical resistance: Due to the chemical stability and non-polarity of the foamed silicone seal, it does not react with most chemical substances, and is insoluble or insoluble with polar substances. Resistant to alcohol, acids (formic acid, acetic acid), strong bases, oxidants (such as H202, HClO, etc.), detergents, animal and vegetable oils, ketones, some lipids, hydrazine. Three. Excellent water resistance, resistance to overheating and water vapor resistance: water is a strong polar material, EPDM is a polymer chain hydrazine, with "hydrophobicity". It is not easy to produce chemical interaction between them, so it has excellent water resistance, overheating resistance and water vapor resistance.

Which material is better for doors and windows sealing strip?

At present, the common door and window sealing strips on the market are mainly used in plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows and other architectural decorative doors and windows. There are three common materials, namely EPDM, silicone rubber and PVC. In the door and window industry, there has always been a controversy, which material of the sealing strip is better, because the input of the door and window sealing strip accounts for a small proportion, but its role can not be ignored. The sealing strip should not only be waterproof, dustproof and windproof, but also be energy-saving, warm and soundproof. In fact, whether it is good or not, the question of who is better is actually a matter of opinion. These three raw materials have their own advantages. However, it is also necessary to consider the manufacturer of the door and window sealing strip, the content of raw materials, the production technology and other reasons, and the performance requirements of the application scenario are also very important.

Sealing strips of different materials, which is better?

Silicone rubber is a rubber whose main chain is composed of silicon and oxygen atoms alternately, and two organic groups are usually connected to the silicon atom. Ordinary silicone rubber is mainly composed of methyl and a small amount of vinyl containing silicon oxygen chain. The introduction of phenyl can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyano can improve the temperature resistance and oil resistance of silicone rubber. Silicone rubber has good low temperature resistance and can generally work at -55°C. After the introduction of phenyl, up to -73. The heat resistance of silicone rubber is also very prominent, at 180 ℃ can work for a long time, slightly higher than 200 ℃ can withstand weeks or longer still elastic, instantaneous resistance to high temperatures above 300 ℃. The gas permeability of silicone rubber is good, and the oxygen transmission rate is higher in synthetic polymers.
