Chaw tsim khoom (lub Hoobkas) ntawm Silicon Cabide cib, phaj, vuas
Cov Silicon Carbide tiv taus ntau yam kua qaub thiab alkalis. Thiab nrog kev ua tau zoo heev ntawm lub zog siab, siab tawv, siab hnav tsis kam, siab kub tsis kam, thiab corrosion tsis kam. Ntau hom duab ntawm cov khoom tshwj xeeb yog tsim rau kev tsuas, petrochemical, metallurgical manufacturing, aerospace thiab nuclear industries, xws li ib puag ncig tshwj xeeb. Peb tuaj yeem ua txhua qhov loj me raws li cov neeg siv khoom thov.
Kev tiv taus kev hnav, lub zog kub siab thiab kev tiv taus corrosion ua rau Reaction Bonded SiC yog cov khoom siv zoo tshaj plaws rau cov khoom siv hnav, xws li cov yeeb nkab liners, cib, vuas, blocks, thiab lwm yam.

Cov ntawv thov silicon carbide phaj:
SiC silicon carbide phaj thiab vuas yog ib hom phaj ceramic tshwj xeeb uas siv dav hauv ntau yam kev lag luam:
Kev Lag Luam Mining, Kev Lag Luam Tshuab, Kev Lag Luam Tshuaj, Kev Lag Luam Crystallite Iav, Kev Lag Luam Khoom Siv Sib Nqus, Metallurgy, Kev Lag Luam Metallurgy, Kev Lag Luam Ntawv, Kev Lag Luam Roj Av, kiln, thiab lwm yam.
Cov khoom siv silicon carbide uas kho kom haum, muaj cov duab: phaj, cib, vuas, phaj radian, ntsia hlau, phaj tiaj tus, yeeb nkab ncaj, yeeb nkab tee, nplhaib, luj tshib, cua daj cua dub thiab lwm yam.
Shandong Zhongpeng Special Ceramics Co., Ltd yog ib qho ntawm cov khoom siv tshiab silicon carbide ceramic loj tshaj plaws hauv Suav teb. SiC technical ceramic: Moh qhov nyuaj yog 9 (New Moh qhov nyuaj yog 13), nrog kev tiv thaiv zoo heev rau kev yaig thiab xeb, kev puas tsuaj zoo heev - kev tiv thaiv thiab kev tiv thaiv oxidation. SiC cov khoom lub neej kev pabcuam yog 4 txog 5 zaug ntev dua li 92% alumina khoom. MOR ntawm RBSiC yog 5 txog 7 zaug ntawm SNBSC, nws tuaj yeem siv rau cov duab nyuaj dua. Cov txheej txheem hais nqe yog ceev, kev xa khoom yog raws li tau cog lus tseg thiab qhov zoo yog qhov thib ob rau tsis muaj leej twg. Peb ib txwm mob siab rau kev sib tw peb lub hom phiaj thiab muab peb lub siab rov qab rau lub zej zog.
