Kev piav qhia ntawm lub hauv paus ntsiab lus ntawm silicon carbide abrasive xuab zeb
Silicon carbide abrasive xuab zeb yog ib qho kev siv abrasive, nws muaj ntau yam kev siv. Lub hauv paus ntsiab lus ntawm abrasive xuab zeb tuaj yeem suav nrog hauv cov hauv qab no: particle sib tsoo, kev ua haujlwm saum npoo, thermal conductivity thiab oxidation tsis kam.Particle sib tsoo yog hais txog me me nag lossis daus thiab deformation ntawm qhov chaw ntawm lub workpiece los ntawm kev sib txhuam thiab cuam tshuam quab yuam thaum lub abrasive. xuab zeb hais yog nyob rau hauv kev sib cuag nrog nto ntawm lub workpiece. Qhov kev sib tsoo no tuaj yeem txo qhov roughness ntawm lub workpiece nto thiab txhim kho nws cov tiav. Lub hardness ntawm silicon carbide abrasive xuab zeb hais yog siab heev, yog li nws yuav ua tau zoo nyob rau hauv kev sib tsoo ntau yam ntaub ntawv, xws li hlau, ceramics thiab plastics.Silicon carbide abrasive xuab zeb muaj ib tug siab deg kev ua si. Nws muaj peev xwm chemically react nrog lwm yam tshuaj, xws li lub cev adsorption thiab chemisorption. Cov cuab yeej no ua rau silicon carbide abrasive xuab zeb nyob rau hauv cov txheej txheem sib tsoo tuaj yeem sib cuag zoo dua nrog lub workpiece nto, thiab ua kom tshem tawm cov ntaub ntawv thiab nto leveling. Yog li ntawd, silicon carbide sib tsoo xuab zeb feem ntau yog siv nyob rau hauv high-precision sib tsoo, polishing thiab zoo sib tsoo txheej txheem.Silicon carbide sib tsoo xuab zeb muaj ib tug siab thermal conductivity. Qhov no txhais tau hais tias cov xuab zeb abrasive muaj peev xwm hloov tau cov cua sov uas tsim los ntawm kev sib txhuam mus rau ib puag ncig ib puag ncig sai dua thaum lub sij hawm sib tsoo, zam qhov teeb meem ntawm overheating lub workpiece. Lub siab thermal conductivity pab txhim kho cov cua kub dissipation kev ua tau zoo ntawm cov xuab zeb sib tsoo, cia nws ua haujlwm ruaj khov rau lub sijhawm ntev. Tsis tas li ntawd, thermal conductivity tiv thaiv cov khoom los ntawm kev hloov pauv theem lossis kev puas tsuaj vim qhov kub thiab txias ntau dhau.Silicon carbide abrasive xuab zeb muaj oxidation zoo. Nyob rau hauv cov txheej txheem ntawm kev kub siab los yog kev sib tsoo ceev, kev sib tsoo cov xuab zeb yuav ntsib kev pheej hmoo ntawm oxidation. Txawm li cas los xij, cov khoom siv silicon carbide muaj oxidation zoo heev thiab tuaj yeem tiv taus cov tshuaj tiv thaiv oxidation ntawm qhov kub thiab txias, ncua kev pab cuam lub neej ntawm cov xuab zeb sib tsoo thiab tswj kev ruaj ntseg ntawm kev sib tsoo.
