Kodi Mawilo Opera a Daimondi N'chiyani?

Mawilo opukutira a diamondi ndi zida zopukutira zomwe zimapangidwa ndi zigawo zitatu zazikulu:

Mbewu Yodula ya Daimondi: Chodulira, chopangidwa ndi diamondi yachilengedwe (yosowa, yokwera mtengo) kapena diamondi yopangidwa (yofala kwambiri, yopangidwa kuti ikhale yofanana). Mbewu za diamondi yopangidwa nthawi zambiri zimakutidwa (monga nickel kapena titaniyamu) kuti zigwirizane bwino ndikuletsa kuwonongeka.
Bond Matrix: Imasunga tinthu ta diamondi m'malo mwake ndipo imawongolera momwe tinthu "timaswekera" (kuwonongeka) mwachangu tikamagwiritsa ntchito. Mitundu yodziwika bwino ya tinthu ta diamondi ndi resin, chitsulo, vitrified, ndi electroplated (zambiri pa izi mu gawo la Technical Info).
Kapangidwe ka Mabowo: Mipata yaying'ono pakati pa chomangira ndi tinthu tating'onoting'ono tomwe timalola kuti choziziritsira chiziyenda bwino, kuchotsa tchipisi, komanso kupewa kutsekeka kwa madzi—kofunikira kwambiri kuti zinthu zizikhala zolondola kwambiri pa kutentha kwambiri.

Zinthu Zofunika Kwambiri pa Mawilo Opukutira a Daimondi

Mawilo opukutira diamondi amatanthauzidwa ndi zinthu zomwe zimawapangitsa kukhala abwino kwambiri pa zipangizo zovuta. Nazi zofunika kwambiri kuziganizira:

1. Kulimba Kwambiri & Kukana Kuvala

Daimondi ili pa nambala 10 pa sikelo ya kuuma kwa Mohs (yomwe ndi yapamwamba kwambiri), zomwe zikutanthauza kuti imatha kupukusa zinthu zolimba mpaka 9 Mohs—kuphatikizapo alumina ceramics, silicon carbide, galasi, ndi tungsten carbide. Mosiyana ndi mawilo a aluminiyamu oxide kapena silicon carbide (omwe amawonongeka msanga pa zipangizo zolimba), mawilo a diamondi amasunga mawonekedwe awo ndipo amadula mphamvu kwa nthawi yayitali ka 50-100, zomwe zimachepetsa ndalama zosinthira zida.

2. Kutha Kupera Molondola

Ndi kukula kwa tinthu tating'onoting'ono tomwe tili ndi 0.5 μm (ma micrometer), mawilo a diamondi amakhala osalala ngati Ra 0.01 μm—ofunika kwambiri pazida zowunikira, zinthu zoyezera magetsi, ndi zipangizo zachipatala komwe ngakhale zolakwika zazing'ono zimayambitsa kulephera.

3. Kukana Kutentha & Kudula Kozizira

Daimondi imakhala ndi mphamvu yotenthetsera kutentha kasanu kuposa mkuwa, zomwe zimapangitsa kuti ichotse kutentha mwachangu ikaphwanyidwa. Izi zimachepetsa "kuwonongeka kwa kutentha" (monga ming'alu, kupsa, kapena kupindika kwa zinthu) muzinthu zomwe zimakhudzidwa ndi kutentha monga galasi, quartz, ndi ziwiya zapamwamba zadothi.

4. Kusintha kwa mawonekedwe

Opanga amasintha mawilo a diamondi kuti agwirizane ndi ntchito zinazake posintha:

Kukula kwa tirigu (kolimba kuti zinthu zichotsedwe mwachangu, kosalala kuti zimalizidwe).
Mtundu wa bond (resin yogwiritsidwa ntchito potentha pang'ono, chitsulo chopera kwambiri).
Mawonekedwe a gudumu (lathyathyathya, chikho, mbale, kapena utali wozungulira) kuti ligwirizane ndi mawonekedwe a ntchitoyo.

Chidziwitso Chaukadaulo: Momwe Mawilo Opera Daimondi Amagwirira Ntchito

Kuti musankhe gudumu la diamondi loyenera, kumvetsetsa tsatanetsatane wake ndikofunikira. Nazi mfundo zofunika kwambiri zaukadaulo:
