Mhando dzeMadhaimani

Rudzi rwedhaimani rinoshandiswa mukukuya nekupukuta mvura rinokanganisa zvikuru mashandiro echigadzirwa chekupedzisira. Madhaimani emumaindasitiri akapatsanurwa muzvikamu zvechisikigo uye zvekugadzira, chimwe nechimwe chinogadzirwa nenzira dzakasiyana-siyana.

Upfu hwedhaimani yechisikigo hunowanzogadzirwa nemadhaimani emhando yepasi, ayo, kunyange asina kukodzera matombo emhando yepamusoro, anowanzo shandiswa mumaindasitiri. Zvisinei, madhaimani echisikigo haawanikwe uye anogona kusiyana-siyana muzviwanikwa zvechisikigo.

Madhaimani ekugadziraKune rumwe rutivi, zvinogadzirwa kuburikidza nemaitiro ekupisa kwakanyanya/kumanikidzwa kwakanyanya. Nzira iyi inosanganisira kushandisa catalyst yesimbi kushandura graphite kuita dhaimani, inowanzonzi single-crystal diamond abrasives. Hunhu hwedhaimani idzi dzekugadzira hunogona kusiyana zvakanyanya, kubva pakuchena kwakanyanya kusvika pakusvibiswa kwakanyanya. Single-crystal diamond micro-powder inogadzirwa nekupwanya zvidimbu zvedhaimani uye wobva waisa micronizing upfu, zvichikonzera chinhu chinoshandiswa zvakanyanya.

Rumwe rudzi rwedhaimani rekugadzira rinogadzirwa nekuputitsa zvinoputika zvakaputirwa pamatanda egirafiti. Kupisa kwakanyanya nekumanikidzwa kunobva mukuputika zvinoshandura girafiti zvakananga kuita dhaimani repolycrystalline, kazhinji zvichikonzera saizi dzemadhaimani dziri pasi pema micron gumi, izvo zvinodawo micronization kuti zvishandiswe mukukuya nekupukuta. Kunyange zvazvo madhaimani epolycrystalline asingashandiswi zvakanyanya semadhaimani e-single-crystal, anowanzo kudhura zvakanyanya.

Pamusoro pezvo, madhaimani madiki anogadzirwa munzvimbo dzakadzorwa nekuputitsa zvinoputika zvepurasitiki. Kuputika uku kunoburitsa zvasara zvine huwandu hushoma hwemadhaimani emhando yepasi, anozivikanwa semadhaimani madiki. Mushure mekuchenesa nekupararira, madhaimani aya madiki anowanzova pasi pe 1 micron. Kunyangwe kugadzirwa kwawo kusina kuoma kupfuura kwemadhaimani e-single-crystal kana polycrystalline, haaenderane nekushanda kwemadhaimani ehukuru hwe micron mukushandiswa kwekukuya nekupukuta.

Pakati pezvinhu zvose zvinokanganisa mashandiro ekukuya nekupukuta kwezvinwiwa, saizi yezvidimbu inokosha. Avhareji yehukuru hwezvidimbu inosarudza mwero wekubvisa zvinhu uye mazinga ekukwenya kana kukwenya kwemusoro. Madhaimani ese ari maviri ane kristalo imwe chete nepolycrystalline anogona kuverengerwa zvichienderana neavhareji chaiyo yehukuru uye percentage tolerance.

Kana uchitsvaga zvigadzirwa zvedhaimani zvemhando yepamusoro, taura neBoreas kuti uvandudze mashandiro ako ekugadzira michina uye mhando yechigadzirwa!
