Girazi mabhero anowanzo kuve nekuoma kuri pakati pe6 ne7, nepo alloy beads ane kuoma kuri pakati pe7.5 ne8.5. Aya maitiro akavakirwa pachiyero chekuomarara cheMohs, chinoyera kuramba kwechinhu kukwenya kana kupinza. Alloy beads, nekuda kwekusanganisirwa kwemasimbi akawanda, ane kuomarara kwepamusoro, zvichirevawo kuti haawanzopfeki-uye anogona kuchengetedza kucheka kwawo nekufamba kwenguva.
1. Kuoma kweGlass Beads
Girazi mabhedhi, sechinhu chakajairika chakasimba chimedu, chinoshandiswa zvakanyanya mukurapa pamusoro pezvinhu zvakaita sesimbi, plastiki, uye huni. Kuomarara kwavo kunowanzo kubva pa6 kusvika pa7, zvichiratidza kugona kwavo kuramba kukwenya kana kudzika kana vachiiswa pasi pesimba rekunze. Zvisinei nekuoma kwazvo, magirazi mabhedhi anogona kunge aine hupenyu hushoma hwesevhisi mune dzimwe nzvimbo-zvinopfekwa.
2. Kuoma kweAlloy Beads
Kuenzaniswa negirazi beads, alloy beads anoratidza yakakosha mukana mukuoma. Alloy mabhedhi anogadzirwa nekusanganisa akawanda masimbi masimbi, zvichikonzera kuoma kwepamusoro uye kukwirira kupfeka kuramba. Kuomarara kwavo kunowanzo kubva pa7.5 kusvika 8.5, zvichiita kuti alloy microbeads inyatsoshanda mukubvisa kuremara kwepamusoro uye kuderedza kukuvadzwa kwekuputira panguva dzakaita sekupfapfaidza nejecha. Iko kuomarara kweiyo alloy microbeads zvakare kunoreva kuti vanochengetedza kuita kwavo kwekucheka kwenguva yakareba, vachivandudza kushanda nesimba uye kuderedza mitengo.
3. Zvishandiso zveGlass Beads uye Alloy Microbeads
Ose magirazi uye alloy microbeads ane huwandu hwakasiyana hwekushandisa mukurapwa kwepamusoro. Girazi mabhedhi anonyanya kushandiswa seabrasives kana mafirita, achinatsiridza kushata uye kupfava kwepasi pezvinhu kuburikidza nekukwesha nekukanganisa. Alloy microbeads, kune rumwe rutivi, anonyanya kushandiswa mukuda kurapwa kwepamusoro maitiro, senge chaiyo sandblasting uye kupfapfaidza, kuti uwane mamwe akacheneswa kupera.
