Munyika yekuyedza zvinhu, kunyanya mapendi nependi, kunzwisisa abrasion kuramba kwakakosha. Apa ndipo pane abrasion yekuyedza michina (inozivikanwawo sekupfeka yekuyedza michina kanaabrasive test machine) come in. Michina iyi yakagadzirirwa kuona kukwanisa kwechinhu kushingirira kukwenya uye kusakara, izvo zvakakosha pakuona kureba nekusimba kwezvigadzirwa zvakasiyana.
ASTM (American Society for Testing and Materials) yakagadzira akati wandei maitiro ekutungamira kuyedzwa kweabrasion. Miyero miviri inocherechedzwa ndeye ASTM D2486 uye ASTM D3450, iyo inotarisa pane akasiyana maficha ekuedzwa kweabrasion.
Iwo ma ASTM mazinga anonyanya kushanda kune yako abrasion bvunzo anosanganisira:
ASTM D2486- Uyu ndiwo chiyero chekuyedza kuyera kuramba kwependi kukukurwa kunokonzerwa nekukwesha.
ASTM D3450-Iyi ndiyo yakajairwa bvunzo nzira ye washability zvivakwa zvemukati zvekuvaka machira.
ASTM D4213- Iyi inzira yakamisikidzwa yekuyedza kukwesha kuramba kwependi nekudzikira uremu.
ASTM D4828-Iyi ndiyo yakajairwa bvunzo nzira yekushambidzika kweiyo organic coating.
ASTM F1319- Iyi inzira yekuyedza inotsanangura maitiro ekuona huwandu hwechifananidzo chinotamiswa pamusoro pejira jena nekukwesha.
ASTM D2486 chiyero chakanyatsogadzirirwa kuyera kupokana kwejasi kukwesha ngura. Muedzo uyu wakanyanya kukosha kupenda nekugadzira vagadziri nekuti inotevedzera mapfekero uye kubvaruka kunoitika mumashandisirwo epasirese. Muedzo uyu unosanganisira kuisa pasi rakavharwa pachiitwa chekukwesha (kazhinji neicho chakataurwa chinokwesha) kuona kugona kwejasi kuramba kukuvara. Mhedzisiro yacho inopa ruzivo rwakakosha mukusimba kwejasi, zvichibatsira vagadziri kuvandudza maumbirwo uye kuona kuti zvigadzirwa zvavo zvinosangana nezvinodiwa nevatengi.
ASTM D3450, kune rumwe rutivi, inobata nekushambidzika kwemukati mekuvaka machira. Iyi chiyero yakakosha pakuongorora kuti zviri nyore sei kucheneswa kwepasi pasina kukuvadza coating. Kuyedza kunosanganisira kushandisa chaiyo yekuchenesa mhinduro uye kukwesha pamusoro kuti uongorore kuramba kwejasi paabrasion uye kugona kwayo kuchengetedza kutaridzika kwayo nekufamba kwenguva. Izvi zvinonyanya kukosha kune mabhanhire anoshandiswa munzvimbo dzine vanhu vakawanda kana nzvimbo dzinoda kucheneswa nguva nenguva, semakicheni nedzimba dzekugezera.
Ose ari maviri ASTM D2486 uye ASTM D3450 anosimbisa kukosha kwekushandisa abrasion tester kunyatsoita bvunzo idzi. Michina iyi yakashongedzerwa neakasiyana maficha ekudzora mamiriro ebvunzo, kuve nechokwadi chakavimbika uye chinodzokororwa mhedzisiro. Nokushandisa anabrasive test machine, vagadziri vanogona kuwana kunzwisisa kwakadzama kwekushanda kwezvigadzirwa zvavo uye kuita zvisarudzo zvine ruzivo pamusoro pekugadzirisa kugadzirisa kana kuvandudzwa kwechigadzirwa.
Pamusoro pezviyero zveASTM izvi, kushandiswa kweabrasion testers hakugumiri papendi uye machira. Maindasitiri akadai semota, aerospace, uye kuvaka zvakare anovimba nekuyedzwa kweabrasion kuti aongorore kusimba kwezvinhu zvinoshandiswa muzvigadzirwa zvavo. Semuyenzaniso, michina iyi inogona kushandiswa kuongorora mashandiro ejasi rekudzivirira pamotokari kana kupfeka kuramba kwemidziyo yepasi kuti ive nechokwadi chekuti inosangana nezviyero zveindasitiri uye zvinodiwa nevatengi.
ASTMabrasion yekuongorora zviyero, kunyanya ASTM D2486 uye ASTM D3450, inoita basa rakakosha mukuongorora kusimba kwependi uye machira. Kushandisa abrasion yekuyedza muchina kwakakosha pakuita bvunzo idzi nemazvo, kupa vanogadzira data ravanoda kuti vavandudze zvigadzirwa zvavo. Sezvo indasitiri ichiramba ichiisa pamberi pemhando uye hupenyu hurefu, kukosha kwekuyedzwa kweabrasion kunongowedzera, zvichiita kuti zviyero izvi uye michina yekuyedza zvishandiswe muzvinhu zvesainzi uye engineering.
