Silicon carbide alloy ceramic wear tube

Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000ºC or higher. Both forms of silicon carbide (SiC) are highly wear resistant with good mechanical properties, including high temperature strength and thermal shock resistance. Our engineers are always available to best advise you on the strengths and weaknesses of ea...

Ultra high molecular weight polyethylene pipe

Ultra-high molecular weight polyethylene (UHMW-PE) is a new kind of engineering thermoplastics with more than 3 million viscosity-average molecular weight. What is UHMWPE Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, intrinsically self-lubricating, anti-adhesion, low temperature resistance and excellent chemical resistance. UHMWPE wear pipe UHMWPE pipe bend UHMWPE pipe for dredginge UHMWPE pipe with flangee Ultra-high molecular weight polyethylene (UHMW full name is ultra-high molecular weight polyethylene pipe) is a thermoplastic engineering plastics with an average molecular weight greater than 1.5 million, which is polymerized by ethylene and butadiene monomer under the action of a catalyst. Ultra high molecular weight polyethylene is superior in comprehensive performance, abrasion ...
