Dawb fused aluminabinder ua kom lub zog sib txuas ntawm cov abrasive thiab substrate. Nrog rau kev tsim kho kev lag luam, binders feem ntau yog siv hauv kev lag luam abrasive thiab sib tsoo log rau coated abrasives los txhim kho lawv cov kev ua tau zoo, xws li thermal stability thiab compressive zog.
Nws yog ib qho tseem ceeb lav ntawm cov khoom zoo, ua lub luag haujlwm tseem ceeb thiab sib cav tias yog ib feem tseem ceeb.
Qee lub sij hawm, thaum kuaj qhov zoo ntawm cov dawb fused alumina, cov ntawv khi kuj yog ib qho tseem ceeb qhia. Tom qab tag nrho, lub binder yog dab tsi tuav cov dawb fused alumina abrasive nplej ua ke, thiab nws tsis tsuas yog txhim kho nws cov kev ua tau zoo tab sis kuj tseem cuam tshuam rau nws cov khoom muaj txiaj ntsig thiab zoo.
Piv txwv li, yog hais tias lub binder particle loj yog ntxhib heev, lub molding compound yuav tsis sib tov tusyees, uas yuav cuam tshuam rau lub hardness thiab lub zog ntawm cov dawb fused alumina.
Yog li ntawd, nyob rau hauv ib txwm muaj xwm txheej, qhov loj me me ntawm dawb fused alumina binders yog qhov zoo. Fine-cov ntaub nplaum nplaum tuaj yeem faib tau ntau qhov sib npaug hauv cov abrasive, txhim kho kev sib cuag nrog lub hardener.
Rau qee cov khoom zoo -grained dawb fused alumina cov khoom, cov binder particle loj yuav tsum tau nyob rau hauv lub micrometer ntau yam.
Yog li ntawd, nws yog ib qho yooj yim kom pom tias qhov loj me thiab qhov ntau ntawm cov ntawv khi ncaj qha cuam tshuam rau cov khoom zoo; qhov no yog qhov peb feem ntau hu ua qhov sib txawv me me uas ua rau muaj qhov sib txawv loj.
Tsis tas li ntawd, nws tsim nyog sau cia tias rau dawb fused alumina, tsis tsuas yog qhov loj me ntawm cov ntaub ntawv tseem ceeb, tab sis hom kev khi kuj tseem ceeb heev. Piv txwv li, dawb aluminium oxide sib tsoo lub log uas tsim los siv cov binders sib txawv yuav muaj cov khoom sib txawv thiab tsim nyog rau kev siv sib txawv.
