Broadly speaking, the following three variables are mainly depended on by silicone rubber gaskets material’s choice, pressure, specifically temperature and medium.
First, we shall talk about the substance for the silicone rubber gaskets that is psychological. In a scenario that was normal, the mental silicone rubber gaskets may be made of several materials, for example carbon-steel, stainless, metal, aluminium, reddish copper, metal, titanium and so forth. Today, their properties that affect seal material’s choice will be released on by one. What comes first is silicone rubber gaskets manufactured from carbon steel. 538 Celsius temperature, particularly when the medium has the house can not be exceeded by the Mental silicone rubber gaskets’s highest working temperature. Furthermore, even though the carbon steel plate that is thin is outstanding in quality, it’s not the right material for the equipment whose working environment includes acid salt fluid nutrient acid or inert liquid fluid. There is nevertheless some thing that needs to be concerned. The gear mishap may often happen, if the carbon steel carries too much stress in the operating state with heated water. Therefore, the carbon-steel silicone rubber gaskets is generally utilized in the acid or alkaline solution whose focus is not quite low. Next, regarding the seal silicone rubber gaskets made from chromium steel, it is implied that 760 Celsius temperature can not be surpassed by its working heat. And its hardness is 160.
Afterward, it is change to discuss the metal seal silicone rubber gaskets. As far as we know, the blend comprises different elements, such as iron, chrome, nickel , molybdenum and copper. This silicone rubber gaskets working temperature can not exceed 760~815 Celsius temperature. It truly is especially requested the equipment that is used to generate the sulphuric acidity. Next, due to the exceptional corrosion- proof house and processability, the aluminum is not unsuitable to function as the chief material of dual-cut silicone rubber gaskets. The Brinell hardness of this silicone rubber gaskets is around 35’s highest and it proceeds operating temperature is 426 heat. As for the metal silicone rubber gaskets, although it has the good corrosion-proofness, it’s not appropriate for acetylene and the acetic acid, ammonium hydroxide, salt in many scenarios. It’s proposed that the mental silicone rubber gaskets’s highest working temperature cannot exceed 260 temperature. How concerning the titanium? Most of the time, its temperature that is working can’t surpass 1093 Celsius temperature. Under the high temperature state, it’s characterized by the great corrosion-proofness. This silicone rubber gaskets is not often employed in the aqueous slkali, in the working condition however, it really is trusted.
Second, we are going to introduce the non- mental seal silicone rubber gaskets material. In addition, there are a lot of materials for the low-psychological seal silicone rubber gaskets, such as natural rubber, chloroprene rubber, fluorubber and so on. Take the organic rubber silicone rubber gaskets for illustration. It has a good rust-proof home for the fragile acid, chloride, sodium and alkali solution, but it could readily been eroded by the oil. Therefore it is unsuitable for the method, for example its operating heat and ozone is about -57~ – 93 temperature. As the rubber, it’s a sort of artificial rubber and thus it can be used in the fluid whose deterioration is moderate for. Besides, this rubber is also corrosion resistant to gas and oil. On foundation of the characteristics of the rubber, the seal silicone rubber gaskets, produced of this rubber, additionally has exactly the same characteristics. It is suggested the working temperature for this particular seal silicone rubber gaskets is around -51~121 Celsius temperature.
