M'dziko loyesa zida, makamaka zokutira ndi utoto, kumvetsetsa kukana kwa abrasion ndikofunikira. Apa ndipamene makina oyesera abrasion (omwe amadziwikanso kuti makina oyesera kuvala kapenamakina oyesera abrasive) bwerani. Makinawa amapangidwa kuti athe kuwunika mphamvu ya chinthu chomwe chimatha kupirira kukangana ndi kutha, zomwe ndizofunikira kuti zinthu zosiyanasiyana zizikhala ndi moyo wautali komanso zolimba.

ASTM (American Society for Testing and Materials) yapanga miyezo ingapo yowongolera kuyezetsa kwa abrasion. Miyezo iwiri yodziwika bwino ndi ASTM D2486 ndi ASTM D3450, yomwe imayang'ana mbali zosiyanasiyana za kuyesa kwa abrasion.

Miyezo ya ASTM yomwe ingagwiritsidwe ntchito pakuyesa kwanu kwa abrasion ndi:

Chithunzi cha ASTM D2486- Uwu ndiye muyeso woyezera kukana kwa utoto kuti usakokoloke chifukwa chokolopa.

Chithunzi cha ASTM D3450- Iyi ndiye njira yoyesera yoyesera yotsuka zamkati mwazomangamanga.

Chithunzi cha ASTM D4213- Iyi ndi njira yokhazikika yoyesera kukana kwa utoto pochotsa kunenepa kwa abrasion.

Chithunzi cha ASTM D4828- Iyi ndiye njira yoyezetsa yoyeserera pakuchanika kwa zokutira za organic.

Chithunzi cha ASTM F1319- Iyi ndi njira yoyesera yomwe imalongosola njira yodziwira kuchuluka kwa chithunzi chomwe chimasamutsidwa pamwamba pa nsalu yoyera posisita.

ASTM D2486 ndi muyezo womwe umapangidwira kuyeza kulimba kwa zokutira kuti zipse dzimbiri. Mayesowa ndi ofunikira kwambiri pakupenta ndi opanga zokutira chifukwa amafanizira kung'ambika komwe kumachitika muzinthu zenizeni. Kuyesaku kumaphatikizapo kupeta pamalo otchingidwa (nthawi zambiri amakhala ndi zinthu zomatira) kuti adziwe momwe zokutirazo zingawonongeke. Zotsatirazi zimapereka chidziwitso chofunikira pa kulimba kwa zokutira, kuthandiza opanga kukonza mapangidwe ndikuwonetsetsa kuti zinthu zawo zikukwaniritsa zomwe ogula amayembekezera.

Komano, ASTM D3450, imakhudzana ndi kutha kwa zokutira zomanga zamkati. Muyezo uwu ndi wofunikira pakuwunika momwe malo angayeretsedwe mosavuta popanda kuwononga zokutira. Kuyezetsa kumaphatikizapo kugwiritsa ntchito njira yoyeretsera ndi kupukuta pamwamba kuti muwone ngati nsabwe za m'madzi zimalimba kuti zipse komanso kuti zisamawoneke bwino pakapita nthawi. Izi ndizofunikira makamaka pazovala zomwe zimagwiritsidwa ntchito m'malo omwe mumakhala anthu ambiri kapena malo omwe amafunikira kuyeretsedwa pafupipafupi, monga khitchini ndi mabafa.

Onse ASTM D2486 ndi ASTM D3450 akugogomezera kufunikira kogwiritsa ntchito abrasion tester poyesa mayesowa molondola. Makinawa ali ndi zinthu zosiyanasiyana zowongolera miyeso yoyeserera, kuwonetsetsa kuti zotsatira zodalirika komanso zobwerezabwereza. Pogwiritsa ntchito amakina oyesera abrasive, opanga amatha kumvetsetsa mozama za momwe zinthu zimagwirira ntchito ndikupanga zisankho zodziwikiratu pakusintha kwapangidwe kapena kukonza kwazinthu.

Kuphatikiza pamiyezo iyi ya ASTM, kugwiritsa ntchito oyesa abrasion sikungokhala utoto ndi zokutira. Makampani monga zamagalimoto, zakuthambo, ndi zomangamanga zimadaliranso kuyesa kwa abrasion kuti awunike kulimba kwa zinthu zomwe zimagwiritsidwa ntchito pazogulitsa zawo. Mwachitsanzo, makinawa atha kugwiritsidwa ntchito kuwunika momwe zokutira zodzitchinjiriza pamagalimoto kapena kukana kwa zinthu zoyala pansi kuti zitsimikizire kuti zikukwaniritsa miyezo yamakampani ndi zofuna za ogula.

Chithunzi cha ASTMmiyezo yoyezetsa abrasion, makamaka ASTM D2486 ndi ASTM D3450, zimagwira ntchito yofunikira pakuwunika kulimba kwa utoto ndi zokutira. Kugwiritsa ntchito makina oyesera abrasion ndikofunikira kuti muyese mayesowa moyenera, kupatsa opanga chidziwitso chomwe akufunikira kuti apititse patsogolo malonda awo. Pamene makampaniwa akupitiriza kuika patsogolo ubwino ndi moyo wautali, kufunikira kwa kuyesa kwa abrasion kudzangowonjezereka, kupanga miyezo iyi ndi makina oyesera kukhala zida zofunika kwambiri pa sayansi ndi zomangamanga.
