Haisheng Rubber takes you in-depth understanding of nitrile rubber

When we customize rubber seals, we must first understand the performance of the relevant rubber and whether it is applicable. Today, Haisheng Rubber takes you to know about nitrile rubber. Nitrile rubber has very good oil resistance, its oil resistance is second only to polysulfide rubber and fluorine rubber, and it has very good abrasion resistance and air tightness. But nitrile rubber also has its limitations. Its disadvantage is that it is not resistant to ozone and aromatic, halogenated hydrocarbons, ketones and ester solvents, and is not suitable for insulation materials. Nitrile rubber has better heat resistance than styrene-butadiene rubber and neoprene rubber, and can work for a long time at a high temperature of 120 ° C. Airtightness is second only to butyl rubber. The properties of nitrile rubber are affected by the content of acrylonitrile. As the content of acrylonitrile increases, the tensile strength, heat resistance, oil resistance, air tightness, and hardness of nitrile rubber increase, but the elasticity and cold resistance decrease. Nitrile rubber

Haisheng Rubber takes you familiar with O-shaped rubber seals

O-rings are the most common mechanical seals because they are cheap, simple to make, reliable, and simple to install. Can withstand tens of Pascals (thousand pounds) of pressure. O-rings can be used in static applications or in dynamic applications where there is relative movement between components, such as rotary pump shafts and hydraulic cylinder pistons. The larger O-type silicone rubber seals are used in aerospace, marine, and solar, and the smaller silicone rubber seals are used in medical equipment and daily necessities. O-rings are suitable for installation on a variety of machinery and equipment, and play a sealing role under static or moving conditions at specified temperatures, pressures, and different liquid and gas media. In machine tools, ships, automobiles, aerospace and navigation equipment, metallurgical machinery, chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery

Haisheng Rubber gives you a better understanding of hydraulic fluoro rubber seals

The fluorine rubber seal ring is the core of the hydraulic equipment and is the guarantee of the normal operation of the hydraulic equipment. Therefore, the installation of hydraulic fluororubber seals is very important. Any errors in the installation process may affect the sealing performance, and then affect the normal operation of the hydraulic equipment. Therefore, before installation, it is necessary for the operator to understand the precautions for the installation of fluoro rubber seals. In addition, the storage work before the installation of the fluoro rubber seals should also be in place. Next, Haisheng Rubber takes you to understand the installation precautions and storage environment of fluoro rubber seals: the matters needing attention when installing fluoro rubber seals in hydraulic cylinders: 1. Check the relevant surfaces of the piston, cylinder barrel and guide bush The purse is clean, burr-free, and without edges. 2. The installation tools must be smooth, without edges and sharp corners, to ensure that the fluorine rubber is not damaged during the installation process.

Osamu of the 24 solar terms

Osamu is the 23rd solar term in the 24 solar terms and the fifth solar term in winter, marking the official start of the winter season. When the sun reaches 285 ° (Xiaohan), it marks the coldest day of the year for Divine Land. Osamu, a "little" character, seems to dissolve the cold in midwinter a lot. Little cold, the coldest time on earth. But in fact, Xiaohan is the coldest time of the year. As the saying goes: "Cold in Sanjiu", Xiaohan is just around Sanjiu. Therefore, "Xiaohan is better than Dahan, and it is not uncommon". The old year is approaching twilight, and the new year is approaching. In the severe cold weather at this time, the hope of the new year is also quiet

Static seal of Haisheng rubber seal

Rubber seals are generally divided into static seals and dynamic seals. As the name implies, static seals serve as a seal under static conditions. This type of seal requires good compression deformation of the material; that is, it has good elasticity and requires the product to be twist-proof during assembly. Anti-cutting, according to the working conditions of the product, you can choose the appropriate material and its hardness. Next, Haisheng Rubber will introduce three common classifications of static seals. 1. O-ring seal As a commonly used rubber ring, the O-ring is used for static sealing in many occasions, and in a few cases for reciprocating sealing and rotary sealing. It mainly uses nitrile rubber, fluorine rubber, neoprene, ethylene-propylene rubber, silicone rubber and other rubber grades, which can be produced according to national standards, and can also be specially designed and manufactured according to the use environment, so that its pressure range: hydraulic pressure ≤9.8Mpa, pneumatic ≤1Mpa,

Haisheng Rubber wishes Happy New Year to Jun

New Year's Day, January 1 of the Gregorian calendar, is commonly known as the "New Year" in most countries in the world. Yuan means "beginning", the beginning of every number is called "yuan"; Dan means "day"; "New Year's Day" means "initial day". New Year's Day is also called "three yuan", that is, the yuan of the year, the yuan of the month, and the yuan of the time. Since New Year's Day was born during the Republic of China and evolved from the Spring Festival, when China just started celebrating New Year's Day, of course, most of its customs and habits were similar to the Spring Festival, or a smaller version of the Spring Festival. After all, New Year's Day is not a traditional festival in our country

Not more O-ring compression is better

The traditional view is that the tighter the O-ring seal is squeezed (ie deformed relative to its "squeezed" state). More squeezing is equal to the O-ring, which forces more force between the mating hardware-that is, the liquid, gas, and dry powder that otherwise prevents flow from between the rubber seal and mating hardware. This is where an O-ring is squeezed more and tends to retain its force (and therefore a better seal) than an O-ring that is squeezed less. The failure of an elastomer to maintain its "pushback" force over time is called compression set. An elastomer with a high compression set (usually more than 80%) no longer returns to its original uncompressed shape when it is not squeezed. However, it is assumed that increasing the squeeze on the O-ring will result in a better density

Analysis of the development trend of the silicone industry in 2015

What is the development trend of the silicone industry? It is reported that the linkage effect of the upstream and downstream industries of the silicone rubber industry has gradually begun to appear, and the development is very rapid. According to statistics, if the proportion of silicone rubber in China's rubber consumption will increase from 6.5% to 33% by 2020, The overall domestic self-sufficiency rate can be increased from about 50% to more than 80%. It can be said that the market potential is unlimited. For details, the following is an analysis of the development trend of the silicone industry in 2015 compiled by Xiaobian. Analysis of the development trend of the silicone industry in 2015. From the perspective of rubber consumption, natural rubber accounts for 41.8%, styrene-butadiene rubber and butadiene rubber together account for 28.4%, while silicone rubber is usually only used in a few non-tire areas such as construction sealants and conductive keys, and only accounts for total rubber consumption Volume of 6.4%. because

What are the selection methods of O-rings for soft seal gate valve accessories?

1. At normal temperature and low pressure, use non-metal soft gaskets; At medium pressure and high temperature, use metal and non-metal combined gaskets or metal gaskets; when temperature and pressure fluctuate greatly, use elastic or self-tightening. Type gasket; under low temperature, corrosive medium or vacuum conditions, the gasket with special properties should be considered. 2. Soft-sealed gate valves can be selected based on experience for less demanding occasions and replaced when inappropriate. 3. For those places with strict requirements, such as explosive, highly toxic and combustible gas, and highly corrosive liquid equipment, reaction tanks and pipeline systems, etc., it should be based on the working pressure, working temperature, corrosiveness of the sealing medium and the combined seal. Use the form of surface. The principle of replacing O-rings under pressure with soft seal gate valves: 1. If it is a middle flange gasket, generally it needs to be first
