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: Is it good to use NBR or EPDM for sealing parts?
- NBR produces industrial rubber products exposed to mineral oils, liquids, and gases
- Q: It's three yuan ethylene propylene sealing stripEPDM rubber sealing strip production enterprises are relatively concentrated or relatively large scale
- Seal doors and windows, air conditioning, furniture seal seal, electrical seal, foaming seal, mechanical seal, rubber strip, automobile windshield, door trim, skeleton, extrusion type seal, E type, P type, D type seal, rubber seal, rubber strip, three composite dense - Sponge - steel reinforced three composite seal, four composite seal, soft and hard composite adhesive tape, plastic soft - hard plastic composite seal construction, sealing strip, modified PVC plastic sealing strip, rubber strip, rubber sealing strip high buildings
- 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: All the seals in the car engines, especially those sealed in the cylinders.
- Before and after the crankshaft oil seal, valve oil seal, camshaft seal, valve cover gasket, oil pad, cylinder gasket, oil pump gasket, oil cooler oil filter gasket, cushion and so on, what's the problem?
- Q: What type of sealing roller bearings.
- 1, bearings, lubricants and types (grease and lubricating oil);2, bearing work environment, the size of space;3, the supporting structure of the shaft has the advantage of allowing angular deviation;4, the circumferential speed of the sealing surface;5, the working temperature of the bearing;6, manufacturing costs.

- 4 、 shell of battery and radio telephone and sheath of electronic transformer shell;5. Insulation layer and sheath of power cable of ship, mine, drilling platform, nuclear power station and other facilities.- traffic equipment1. Road and bridge expansion joints;2, road safety facilities, buffer anti-collision components;3, container sealing strip.
- Q: How to choose the sealing ring material, sealing ring of different materials, what is the difference?
- Insulation performance,butSILSilicone rubber sealing ring tensile strength than general rubber poor, and no oil resistanceSIL;The silicon rubber sealing ring is suitable for household electricityAppliances such as electric water heaters, electric irons, microwave ovens, etc.,
- Q: What's the difference between a seal and a sealing strip?
- There are so many seals that you can use them where they need to be sealed. Powder focus can be used to make seals.
- Q: What are the storage conditions for seals?
- First of all, the pressure is an important factor affecting the quality of seals, the pressure level, the length of the pressure cycle cycle, the seal damage (such as extrusion) have a great impact. The higher the pressure, the greater the influence of other factors on the performance of the seal, such as temperature, speed, the material of the seal, the clearance between the piston and the cylinder, the clearance between the piston and the cylinder head.Another is the temperature and friction, it is difficult to describe the maximum use temperature and minimum use temperature of a sealing material, because it is the result of a series of factors. The piston and piston rod have different operating temperatures, so we should choose them differently. Another is the seal product surface roughness, surface characteristics, pressure, medium, temperature, sealing materials, seals type and speed of movement, these are the factors affecting the seal.The last is surface treatment. Experience has shown that the characteristics of the surface of the cylinder piston and the piston rod have a great influence on the life of the seal. Surface characteristics are defined by the values of surface roughness RA. RA is the arithmetic mean of the shape of the surface deviating from the absolute value of the center line. However, these values do not fully indicate the effect of surface conditions on the seals, because even under the same roughness, different surface shape features can cause wear of seals to varying degrees of seal.
- Q: What's the difference between the sealing ring shaft and the bore?
- For hydraulic cylinders, the fixed shaft is used. If it moves with the piston rod, it is the hole. Or, if it is installed on the piston, that is the hole, mainly by mouth to seal the outer lip. On the contrary, if it is sealed by the inner lip, it is used for shafts.
