High mechanical strength corrosion resistance Seal rings

Products Introduction  

Seal rings under ''XING KAI " trademark, adopts advanced pressureless sintered silicon carbide  technology .We can supply our customers with high performance cost ratio and high quality seal rings in various materials of silicon carbide.

This series of seal rings are widely used in the fields of machinery,petroleum,chemical industry,water treatment,aerospace,ship,metallurgy and nuclear power etc.

This series of products are widely used for protection of body, vehicle armor, specialized building and various specialized vehicles.

Because silicon carbide materials has stable chemical properties, high thermal conductivity, low thermal expansion coefficient, low density, good wear resistance, high hardness, high mechanical strength and chemical corrosion resistance characteristics, so has developed rapidly in the field of materials.

Silicon carbide ceramics began in 1960s, silicon carbide was mainly used in mechanical grinding and refractories. However, with the development of advanced ceramics, people are no longer satisfied with the preparation of traditional silicon carbide ceramics. Various kinds of multiphase ceramics based on silicon carbide ceramics have appeared and improved the properties of single-phase materials,which making silicon carbide ceramics more widely in ceramic ball bearings, valves, semiconductor materials, measuring instruments, Aerospace, chemical and other fields.

Our company uses pressureless sintering to make silicon carbide ceramic products. The silicon carbide ceramic product is made by a compact of high performance submicron silicon carbide powder pressureless sintering material. It doesn`t contain free silicon and fine grain size. The purity of silicon carbide is more than 98%, and it has high temperature resistance, high strength, high hardness, high corrosion resistance, light specific gravity, oxidation resistance and other excellent properties. It is the first choice material for manufacturing mechanical seal ring, sandblasting nozzle, bulletproof armor and magnetic pump, shielding pump assembly at home and abroad. It is especially suitable for strong acid and strong base transportation of corrosive medium.

Transportation and package

1. Transportation and handling: During the transportation process, theCeramic armor Products shall not be dragged with hard materials. It should be light unloading to reduce packaging crushing.

2. Storage: The Ceramic armor Products should be stored in a cool and dry place, to prevent rupture of bags. Storage should away from sources of pollution.

3. Non-flooding: The  Ceramic armor Products  is easy brolen, so in the transportation, storage and the process, we must absolutely prevent carefully to insure the quantity of the products.
