Silicon Carbide of Vickers Hardness of 2000kg/mm2, offers superior protection for sliding abrasion applications
Silicon Carbide of Vickers Hardness of 2000kg/mm2, offers superior protection for sliding abrasion applications
Looking for superior protection in sliding abrasion applications? Look no further than our factory's Silicon Carbide with Vickers Hardness of 2000kg/mm2. Trust us for high-quality products.
Silicon carbide ceramic: Moh's hardness is 9.0~9.2, Silicon Carbide of Vickers Hardness of 2100kg/mm2, offers superior protection for sliding abrasion applicationswith excellent resistance to erosion and corrosion, excellent abrasion-resistance and anti-oxidation. It is 4 to 5 times stronger than nitride bonded silicon carbide. The service life is 7 to 10 times longer than alumina material. The MOR of RBSiC is 5 to 7 times that of SNBSC, it can be used for more complex shapes.Silicon carbide wear resistance, it is synthesized from silicon carbide and carbon at high temperature,belongs to a kind of silicon carbide product.The silicon carbide wear resistance parts are widely used in mining,ore crushing,screening and transport of high wear,high corrosive fluids,also very suitable for mechanical products with high precision and sealing requirements,such as high pressure pump,magnetic pump etc.Is a new type of wear resistance material.Reaction-bonded silicon carbide wear resistance bushing has the characteristics of high hardness,high wear resistance,impact resistance,high temperature resistance,acid and alkali corrosion resistance and so on,and the actual service life is more than 6 times that of polyurethane.It is especially suitable for the operation of classification, concentration and dehydration of strong abrasive and coarse-grained materials,has been successfully applied in many mines.Our company is a professional silicon carbide wear resistance ceramic products supplier,hardness second only to diamond,with high wear resistance,long service life features.The wear resistance pipe and elbow that produced with silicon carbide wear resistance lining,its ceramic lining thickness is 6-35mm,the structure is to install the already sintered ceramic tube into the corresponding caliber steel tube, with the glue in the middle.Wear resistance ceramic pipes have the following properties compared with the previous adopted cast-stone pipes,wear-resistant alloy cast steel pipes and ceramic composite pipes. Reaction bonded silicon carbide (RBSC) has excellent wear resistant peformance, good properties at elevated temperatures, good erosion and abrasive resistance, these properties can be utilised in a variety of applications such as pipe liners, ceramic elbow, spray nozzles, shot blast nozzles and hydrocyclone components.ZPC linings far outlast tiled and metallic liners. ZPC silicon carbide ceramics are thermal shock resistance and abrasion resistant which results in extended run times and reduced downtime. The reaction bonded silicion carbide ceramic ( RBSIC) is an ideal wear resistant material, which is especially suitable for the strong abrasive, coarse particles, classification, concentration, dehydration and other operations. Due to the above properties, the RBSiC / SiSiC silicon carbide liner elbow / liner tube can effectively protect the part from high wear and temperature so as to prolong the service life of the equipment.
