Cov khoom siv hlau sib tsoo sponge sandpaper yog ua los ntawm abrasive bonded rau cov ntaub ntawv yooj yim xws li ntawv thiab ntaub. Nws yog cov cuab yeej tseem ceeb rau kev sib tsoo thiab polishing. Daim txhuam cev sandpaper tau muab faib ua daim ntawv siv hauv paus thiab daim ntaub ntawv siv lub hauv paus: daim ntawv siv lub hauv paus yog qhov nyuaj thiab tuaj yeem zom tawm qhov siab-smoothness. Daim ntawv siv lub hauv paus sponge sandpaper yog siv hauv kev sib tsoo zoo thiab kev sib tsoo zoo heev. Cov ntaub siv lub hauv paus muaj zog dua li daim ntawv siv lub hauv paus, thiab tsis tshua muaj siab rau qhov kub thiab av noo tshaj li daim ntawv siv lub hauv paus. Nws yuav tsis poob stability vim qhov kub thiab av noo. Ntaub sponge sandpaper yog ntau ruaj dua li daim txhuam cev sandpaper. Feem ntau siv abrasives hauv cov rooj tog tsim khoom yog aluminium oxide, silicon carbide, zirconium oxide aluminium, garnet, thiab cov ntawv xuas tes ua siv iav xuab zeb ua abrasive.
Cov yam ntxwv ntawm cov khoom sib tsoo hlau sponge sandpaper: coarse sib tsoo, siab plasticity, loj sib tsoo cheeb tsam, coarse grain loj yog xaiv kom tsis txhob nti embedding, mos workpiece, thiab lwm yam.; nplua nplej loj yog xaiv rau kev sib tsoo zoo thiab ua haujlwm nyuaj. Cov khoom siv hlau sib tsoo yog sib txuas nrog lub hauv paus siv los ntawm kev sib tsoo. Cov nplaum yuav tsum muaj zog, elasticity, kub tsis kam, dej tsis kam, thiab lwm yam.
Waterproof sandpaperyog tsuas yog siv rau kev sib tsoo thiab polishing ntawm tsheb, rooj tog zaum, tawv, cov khoom siv hauv tsev thiab cov khoom siv kho tshuab. Qhov sib txawv ntawm cov xuab zeb nplej ntawm cov ntawv xuab zeb tsis muaj dej yog me dua, thiab cov khoom crushed kuj me dua. Thaum siv dej, cov khoom crushed yuav ntws tawm nrog dej, yog li nws yuav tsum tau siv nrog dej. Yog tias cov ntawv xuab zeb tsis muaj dej siv rau kev sib tsoo qhuav, cov khoom tawg yuav nyob twj ywm hauv qhov khoob ntawm cov xuab zeb nplej, ua rau saum npoo ntawm cov ntawv xuab zeb tsis muaj dej tsis zoo thiab tsis tuaj yeem ua tiav nws cov txiaj ntsig qub. Cov ntawv xuab zeb qhuav tsis yog teeb meem. Qhov sib txawv ntawm nws cov xuab zeb nplej loj dua, thiab cov khoom crushed kuj loj dua. Thaum lub sij hawm sib tsoo, cov khoom crushed yuav poob vim qhov khoob loj, yog li nws tsis tas yuav siv dej.
Nta ntawmwaterproof sandpaper: sib tsoo efficiency yog nce los ntawm 30-50%, lub neej ntev, tsawg tshav kub generated los ntawm kev sib tsoo, siab zog, tsim kua muag kuj, zoo anti-clogging nyhuv, thiab tsis txhob fading ntawm sandpaper thiab cuam tshuam qhov zoo ntawm lub workpiece.
