Silicon carbide seal rings Definition - silicon carbide material, depending on the process, after a certain production methods, the production of a silicon carbide products. Its purpose - use is quite extensive, a variety of mechanical products can be applied to, depending on the specifications, the production of different types of products, and ultimately to play a role in sealing. How to develop silicon carbide seal ring market - depending on the product positioning market, according to market distribution brand. Prospects silicon carbide seal ring - prospects for development is still quite widely, in general, based on the current process, innovation, products more promising.
Feature
1. plasticity - as long as the silicon carbide material has a certain process, it may be compressed into various shapes of blank, then a second and can be processed, shaped into products that customers need.
2. corrosion resistance - silicon carbide seal ring may be in the acid environment, the sealing effect is not reduced.
3. abrasion resistance - silicon carbide seal ring through a certain finishing process, so to achieve high-precision flat and smooth, plus the wear resistance of silicon carbide, silicon carbide seal ring so you can use mutual friction. In high-temperature performance, wear performance is not reduced.
4. High temperature resistance - due to the material properties of silicon carbide, silicon carbide seal ring and therefore has a high temperature resistance, depending on the process, high temperature performance is not the same. The reaction sintered silicon carbide seal ring can be used at 1300 degrees without pressure sintered silicon carbide seal ring can reach 1600 degrees.
Here are some of the pressure sintered silicon carbide products, physical and chemical parameters:

- Q:What equipment is needed to produce rubber seals and what is the production process?,
- Hello I made the seal! You do rubber ring to do large-scale (mixer, pre forming, opening machine, cutting machine, vulcanizing machine, trimming machine, testing equipment, there are many, I will not say!
- Q:Replacement seals, but it does not feel like a O ring, ask this solenoid valve seals what is the name, specifications how to express?
- The form of the spool is globe, V-ball, hemisphere, butterfly valve plate and other types.The form of the valve must be selected according to the characteristics of various valves, the general will use the plunger valve.
- Q:What are the differences between silicone rubber and butyl rubber in the use of water seals for home improvement?Which is better for tightness, durability and heat resistance?Looked at each answer, still confused, at present most of the water seals are used Ding Qing, even if very small seals, why?
- Silicone rubber is superior in sealing, durability and heat resistance,
- Q:What are the common sealing forms of hydraulic cylinders?
- The common sealing forms include clearance seal, friction ring seal and sealing ring seal. 1, the gap seal to rely on the relative movement of the small gap between the surface to prevent leakage. In order to improve the sealing capacity of the device, several small annular grooves are often made on the surface of the piston to increase the resistance of the oil through clearance. It has the advantages of simple structure, small frictional resistance, resistant to high temperature, but the leakage of large, high processing requirements, can not restore the original capacity after abrasion is only used in small size, low pressure, high speed of relative movement between the cylinder and the piston.
- Q:What are the seals that are resistant to 500 degrees of high temperature?Airtight chamber gas temperature up to 500 degrees, what are the appropriate seals available? Thank you
- Airtight container seals are static seal, you can use the "flexible graphite" material made of seals, capable of more than 1000 degrees high temperature. (dynamic seal does not apply).
- Q:You want to ask knowledgeable friends. I want to do at home produced small seal factory. The former is to buy it do seal butterfly valve. Now they want to engage in their own ring. Do not know what equipment and capital equipment. Then buy new and used funds is how much. Is the production of multi-level sealing ring and PTFE. What materials should I indebted forever
- These two are completely different materials, the rubber ring is generally rubber, PTFE is plastic, the production process is not the same. Not familiar with, or first learn more professional knowledge!
- Q:What is the maximum resistance to the seal in the hydraulic system currently being produced?
- Therefore, in order to improve the sealing capacity, not only rely on seals, good structure is also very important. You say, if the light takes into consideration the seal, there is no problem with the regular 50MPa (usually around 30).
- Q:How should the piston rings for piston wear be chosen? What is the national standard?
- Cylinder piston due to long-term reciprocating motion, reciprocating piston seals should be used to require wear-resistant, oil corrosion resistance, hardness is best at about 85 degrees.The choice of sealing ring material is of great importance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring.
- Q:All the seals in the car engines, especially those sealed in the cylinders.
- Valve oil seal, piston ring, front and rear crankshaft oil seal.
- Q:What's the difference between an oil seal and a seal? Is it the same thing?
- The seal is a general term for all products that are sealed. They include O rings, oil seals, seals for piston hydraulic cylinders, dust rings, and so on,
