Yuav ua li cas txhim kho mechanical zog ntawm grind log
Sep 06, 2022
Txhawm rau txhim kho cov cua sov ua haujlwm thiab lub zog txhua yam ntawm phenolic resin binder hauv pob zeb diamond sib tsoo lub log, kev hloov kho ntawm phenolic resin tau ua tiav los ntawm kev ntxiv ntau cov khoom ntim rau hauv cov txheej txheem ntawm kev sib tsoo log.
Yog tias tooj liab hmoov ntxiv, qhov kub tsis kam ntawm resin tuaj yeem txhim kho.
Ntxiv zinc oxide, chromium oxide thiab lwm yam khoom tuaj yeem txhim kho lub zog ntawm cov khoom siv.
Qhov sib ntxiv ntawm flake graphite, molybdenum disulfide thiab lwm yam ntaub ntawv mos tuaj yeem txhim kho qhov kev sib tsoo ntawm cov khoom siv sib txuas ua ke.
Txawm li cas los xij, txoj hauv kev zoo tshaj plaws los txhim kho cov khoom ntawm phenolic resin yog ntxiv cov organic modifiers, uas tej zaum yuav yog vim cov khoom siv organic sib haum nrog phenolic resin nyob rau hauv cov nqe lus ntawm cov qauv thiab cov khoom saum npoo dua li cov khoom tsis muaj zog.
Polyimide resin yog ib qho ntawm cov khoom siv hluav taws xob, polyimide resin raws li kev npaj ntawm pob zeb diamond sib tsoo log thawj zaug hauv Tebchaws Meskas, tom qab ntawd siv thoob plaws ntiaj teb, nws cov yam ntxwv loj tshaj plaws yog kev sib tsoo log muaj thermal stability, tuaj yeem siv tau 250 degree. ntev ntev, ntau durability yog siab tshaj phenolic resin bonded sib tsoo log, feem ntau siv nyob rau hauv nyuaj abrasive sib tsoo log load ntawm sib tsoo.
Epoxy resin muaj dej tsis kam thiab muaj zog adhesion, tab sis nws cov cua kub tsis kam. Hauv kev npaj cov cuab yeej abrasive, nws feem ntau yog tov nrog phenolic resin lossis polyimide resin, thiab lwm yam, uas tuaj yeem txhim kho lub zog ntawm cov khoom siv raw khoom, tsis tas yuav txo qhov kub ntawm cov ntaub ntawv.
Polyurethane resin kuj tseem muaj cov cua kub tsis zoo, tab sis cov abrasive ua los ntawm nws yog lub zog zoo thiab feem ntau haum rau kev sib tsoo lub teeb.
