Tej teeb meem thiab kev daws teeb meem ntawm Sand Belts

(1) Sandbelt yog mos heev

Lo lus nug no feem ntau tshwm sim ntawm cov xuab zeb siv cov kua nplaum tsiaj, tshwj xeeb tshaj yog thaum lub caij qhuav. Tsiaj kua nplaum yog me ntsis hygroscopic thiab ua mos thiab nplaum. Yog li ntawd, nyob rau hauv qhov chaw qhuav los yog av noo, cov xuab zeb siv uas tsim los ntawm semi resin los yog tag nrho resin binders yuav tsum tau xaiv. Nws tsis pom zoo kom quav cov xuab zeb daim kab xev ntim cov tsiaj cov kua nplaum ntxov dhau los tiv thaiv kev nqus dej ntau dhau. Yog tias muaj kev tso cai, nws tseem tuaj yeem ua kom qhuav los yog qhuav cov kua nplaum tom qab raug cov dej noo, tab sis qhov kub thiab txias yuav tsum tsis txhob siab dhau los tiv thaiv foaming lossis coking ntawm cov nplaum nplaum.

(2) Lub abrasive yog me ntsis npub tab sis tsis poob

Thaum sib tsoo nrog abrasive siv, yog tias lub log sib cuag yog mos heev, tej zaum yuav muaj qhov xwm txheej uas cov abrasive ntawm cov xuab zeb ntog tsis poob tab sis tsis ntse. Yog tias muaj qhov xwm txheej zoo li no, kev sib tsoo siab yuav tsum tau ntxiv, lossis cov log sib zog sib zog yuav tsum tau hloov, lossis cov log sib txuas nrog lub zog dav dua yuav tsum tau hloov, lossis kev sib cuag lub log nrog cov kab me me yuav tsum tau hloov, lossis cov kab nrawm ntawm txoj siv xuab zeb yuav tsum tau hloov. txo qis, thiab lwm yam, txhawm rau daws qhov teeb meem uas cov xuab zeb nto tsis ntse.

(3) Cov xuab zeb tshem tawm yooj yim, raug lub hauv paus

Qhov no feem ntau yog vim qhov tsis muaj zog ntawm cov khoom abrasive, thiab cov xuab zeb siv yuav tsum tau hloov. Tej zaum yuav tsum tau xaiv ib lub log softer los yog loj dua txoj kab uas hla ntawm lub log yuav tsum tau xaiv los ua kom lub vojvoog curvature ntawm cov xuab zeb siv thiab txo kev sib tsoo siab, los yog ib tug nqaim iav tiv tauj log yuav tsum tau xaiv los mus nce lub linear ceev ntawm cov xuab zeb siv.

(4) Abrasive txheej thaiv

Qhov laj thawj tseem ceeb yog qhov kev xaiv ntawm cov xuab zeb siv tsis raug. Yog tias ua cov xim, nws raug nquahu kom siv cov xuab zeb siv nrog cov coatings ntxiv. Piv txwv li, thaum ua cov khoom siv hlau mos xws li aluminium alloy, stainless hlau, tooj liab, thiab lwm yam, nws yog ib qho tsim nyog yuav tsum siv cov xuab zeb resistant siv cov dej uas tiv taus smoothness thiab coolant los tiv thaiv dej thiab ya raws. Thaum sib tsoo ntoo thiab nws cov khoom, nws raug nquahu kom xaiv cov khoom abrasive xws li dub silicon carbide lossis xim av corundum.
