Lifaha tsa khalase hangata li thatafala lipakeng tsa 6 le 7, athe lifaha tsa alloy li na le boima bo pakeng tsa 7.5 le 8.5. Litekanyetso tsena li ipapisitse le sekala sa boima ba Mohs, se lekanyang ho hana ha thepa ho ingoaea kapa ho indenting. Lifaha tsa alloy, ka lebaka la ho kenyelletsa likarolo tse ngata tsa tšepe, li thatafala ho feta tekano, ho bolelang hore li khona ho khathala-'me li ka boloka matla a tsona a ho itšeha ha nako e ntse e ea.

2. Ho thatafala ha Lifaha tsa Alloy
Ha ho bapisoa le likhaba tsa khalase, lifaha tsa alloy li bonts'a molemo o moholo oa ho thatafala. Lifaha tsa alloy li entsoe ka ho kopanya lisebelisoa tse ngata tsa tšepe, ho fella ka ho thatafala ho hoholo le ho hanyetsa ho hoholo hoa ho apara. Ho thatafala ha tsona ho tloha ho 7.5 ho isa ho 8.5, ho etsa hore li-microbeads tsa alloy li sebetse hantle ho tlosa bofokoli ba bokaholimo le ho fokotsa ts'enyehelo ea ho roala nakong ea ts'ebetso e kang ho fafatsa le ho qhomisa lehlabathe. Boima bo phahameng ba li-microbeads tsa alloy bo boetse bo bolela hore ba boloka ts'ebetso ea bona ea ho itšeha nako e telele, ho ntlafatsa ts'ebetso le ho fokotsa litšenyehelo.
3. Ts'ebeliso ea Lifaha tsa Khalase le Alloy Microbeads
