When it comes to rubber sealing strip, we must be familiar with it, because this small thing is indispensable for sealing in our daily life. The most common are the doors and windows in our families, the figure of rubber seals, and the existence of rubber seals in our daily mechanical products. Even the "family" with rubber seals in cars and ships. Although rubber sealing strips are widely used, do you know the standard of rubber sealing strips? It doesn't matter what I don't know. Today, I will introduce you the standard of rubber sealing strip.

Introduction of rubber sealing strip standard

Rubber sealing strip, as the name implies, refers to the sealing strip made of rubber, which is mainly used in the fields of doors and windows, machinery, automobiles, ships and so on. In addition to the functions of fixing and sealing, it also has the functions of dust prevention, insect prevention, sound insulation and vibration reduction. The standard of rubber sealing strip is set according to the classification of rubber sealing strip. The standard of rubber sealing strip is different for different classification. The following is a brief introduction to the standard of rubber sealing strip according to the classification of rubber sealing strip.

Standard vulcanization classification of rubber sealing strips

The curing method can be divided into two categories: discontinuous curing method and continuous curing method. Non-continuous vulcanization: cut the rubber strip according to a certain length, put one cut into the vulcanization tank for vulcanization, and then put the formed rubber strip into the corresponding mold for vulcanization to produce the final product; In non-continuous vulcanization, the standard of rubber sealing strip is that the finished product should be soft, not too rigid, flat and smooth on the plane, and there should be no noise. Continuous vulcanization: The basic requirements of continuous vulcanization are the same as that of non-continuous vulcanization. The only difference is that the production process is not cut into sections, but continuous. The fixed number of meters is usually more than 100 meters; During continuous vulcanization, the standard of rubber sealing strip should be flexible, not too rigid, flat and smooth on the plane, and not to be cracked.

Standard material classification of rubber sealing strip

　　The basic materials of rubber sealing strip are divided into three types: dense rubber, sponge rubber and hard rubber. These three kinds are of high quality and low quality, and will cause material loss in the process of production. Even high-quality solid rubber, sponge rubber and hard rubber will produce inferior rubber sealing strips in the production process. Therefore, in the classification of materials, not only the quality of materials should be taken as the standard of rubber sealing strips, but also the finished rubber sealing strips should be reviewed. The audit criteria are: softness, not too rigid, flat and smooth on the plane, without bulge.　　

　To sum up, it is the introduction of the rubber sealing strip standard. I hope that through the compilation of the small editor, we can have a certain understanding of the rubber sealing strip, which can help us in our daily life.
