Dia3mm SiC Ceramic pob Silicon carbide Ceramic Polycrystaline

SiC ceramics muaj qhov nyuaj heev, thib ob tsuas yog pob zeb diamond, ua rau nws zoo heev hauv kev tiv thaiv kev hnav, kev tiv thaiv khawb thiab lwm yam. Tib lub sijhawm, nws kuj muaj lub zog khoov siab thiab lub zog compressive, thiab tuaj yeem tswj tau qhov ua tau zoo hauv qhov chaw nyuaj xws li kub thiab siab. Lub ntsiab lus yaj ntawm silicon carbide ceramics yog siab txog 2700 ℃, uas tuaj yeem khiav ntev hauv qhov chaw kub thiab tsis yooj yim rau deformation thiab degradation. Tsis tas li ntawd, silicon carbide ceramics muaj kev tiv thaiv corrosion zoo rau feem ntau cov kua qaub, cov hauv paus, ntsev thiab lwm yam tshuaj lom neeg, thiab tsim nyog rau ntau yam tshuaj lom neeg ib puag ncig. Thaum kawg, nws kuj muaj cov coefficient qis ntawm thermal expansion, uas tuaj yeem tswj tau qhov ntev hauv qhov kub thiab txias hloov pauv.

Cov ntawv thov ntawm SiC ceramics

Cov khoom siv ua los ntawm silicon carbide yog siv dav hauv kev tsim cov khoom siv refractory, xws li cov ntaub thaiv cua sov, lub hau cua sov, thiab cov thawv kub siab, vim nws qhov kub siab thiab tiv taus corrosion. Lub caij no, nws qhov nyuaj nruab nrab ntawm abrasive thiab txawm tias cov noob yog siv dav hauv kev txiav, sib tsoo, polishing thiab lwm yam txheej txheem. Silicon carbide ceramic nres pads muaj cov coefficient siab ntawm kev sib txhuam thiab kev tiv taus abrasion, uas tuaj yeem siv rau hauv lub kaw lus nres ntawm lub tsheb, tsheb ciav hlau thiab lwm yam tsheb thauj mus los. Tsis tas li ntawd, nws tuaj yeem siv rau cov phaj tiv thaiv kev hnav, scraper conveyors, thoob thoob thiab lwm yam khoom siv kom txo tau cov khoom siv hnav. Silicon carbide ceramic heat exchanger muaj kev ua tau zoo heev thiab siv dav hauv hluav taws xob, roj av, tshuaj lom neeg thiab lwm yam lag luam. Thaum kawg, silicon carbide ceramic cav qhov chaw tuaj yeem tswj tau qhov ua tau zoo hauv qhov kub thiab txias siab, txhim kho lub zog cav thiab kev ua haujlwm zoo.
