Kodi diamondi ingathyoledwe ndi nyundo?
Zamkatimu
Daimondi ndiye chinthu chovuta kwambiri padziko lonse lapansi, koma ngakhale ndi chimenecho, imatha kukhala pachiwopsezo chomenyedwa ndi nyundo.
Monga lamulo, ma diamondi ali ndi magawo osiyanasiyana a mphamvu kapena kuuma. Ubwino ndi ungwiro wa kapangidwe ka cubic lattice zimakhudza mlingo wa mphamvu. Choncho, diamondi ali ndi mfundo zofooka mu kapangidwe kake zomwe zimawalola kuthyoledwa ndi nyundo.
Mutha kuswa diamondi ndi nyundo motere:
- Sankhani diamondi yokhala ndi zophatikiza zamkati ndi zolakwika
- Ikani diamondi pamalo olimba
- Menyani kwambiri kuti mugunde pamalo ofooka kwambiri pamiyala ya diamondi.
Ndifotokoza zambiri pansipa.
Kodi diamondi ingathyoledwe ndi nyundo?
Kulimba kumatanthauza kuthekera kwa chinthu kukana kuthyoka kapena kugwa. Koma inde, mutha kuswa diamondi ndi nyundo. Zinthu zotsatirazi zikuwonetsa kusatetezeka kwa diamondi kuti asweke komanso chifukwa chake mutha kuwaphwanya mwamphamvu ndi nyundo.
diamondi geometry
Mapangidwe a diamondi ali ndi cleavage yabwino, yomwe imapangitsa kuti ikhale yosavuta kuthyoka ngati kuwombako kulunjika pamalo oyenera.
Kung'ambika kwa macroscopic kwa diamondi kumawonetsa kufooka kwake. Tiyenera kuzindikira kuti kuuma ndi mphamvu ndizosiyana. Daimondi ndi yolimba, koma nyundo ndi yamphamvu. Komabe, ndizovuta kuthyola diamondi ndi nyundo, koma iyi ikhoza kukhala njira yokhayo yotulukira ngati mulibe odula diamondi.
Kapangidwe ka mkati kamakhala ndi maatomu a carbon opangidwa ndi mankhwala. Ma atomu a kaboni amapangidwa molingana kapena m'mipangidwe ya lattice, ndipo maatomu a carbon ndi ovuta kuwononga.
Chiwerengero cha ma atomu pa voliyumu ya unit
Mapangidwe a cubic a lattice ya diamondi ndi apadera chifukwa ali ndi ma atomu ambiri ndi ma bond pa voliyumu iliyonse. Izi zimapanga maziko a kuuma kwa diamondi. The cubic lattice kumawonjezera kusasunthika kwa maatomu a carbon.
Momwe mungaswe diamondi ndi nyundo
Monga tafotokozera pamwambapa, kuswa diamondi ndi nyundo wamba kapena nyundo si ntchito yophweka, koma zotheka.
Gwiritsani ntchito mphamvu zambiri kuti mupange mphamvu zokwanira kuti muphwanye diamondi. Apo ayi, diamondi idzakhalabe yosasunthika. Tiyeni tiphwanye diamondi.
1: Sankhani diamondi yomwe ndi yosavuta kuthyola
Pali mitundu yosiyanasiyana ya diamondi yokhala ndi magawo osiyanasiyana a kuuma kapena kuuma. Kukhazikika kumatsimikizira kapena kuyika kukhazikika kwa diamondi, zomwe ndizofunikira kwambiri pakuswa diamondi ndi nyundo.
Chifukwa chake, pezani diamondi yokhala ndi zophatikiza zamkati ndi zolakwika kuti ntchito yanu ikhale yosavuta.
Gawo 2: Kusankha Surface
Tikayang'ana mphamvu ya nyundo ndi kulimba kwa diamondi, mumafunika malo olimba kuti mugunde diamondi. Ndikupangira kuyika diamondi pa pepala lachitsulo cholimba kapena mwala. Mukumufinya.
Khwerero 3: Kuwongolera nyundo
Kuti khama lanu liziyenda bwino, wongolerani nkhonyayo kuti kupanikizika kwakukulu kulowetsedwe ku malo ofooka kwambiri a diamondi yamkati.
Ndemanga: Sungani diamondiyobe ngakhale mutamenyedwa ndi nyundo. Monga momwe zimayembekezeredwa, kuphulika kwa nyundo kungafooke ngati diamondi yatuluka kuchokera ku nyundo. Gwirani diamondi monga momwe mwalimbikitsira, kapena gwiritsani ntchito njira ina iliyonse yomwe muli nayo kuti mutsimikizire kukhazikika kwa diamondi.
Mafunso ofunsidwa kawirikawiri
Kodi diamondi zonse zili ndi mphamvu ndi kulimba kofanana?
Ayi. Ubwino ndi ungwiro wa mapangidwe a cubic lattice wa diamondi zimatsimikizira kuuma ndi mphamvu. Koma khalidwe la carbon-carbon bonds limasiyanasiyana chifukwa cha nyengo monga kutentha. (1)
Kodi pali kusiyana kotani pakati pa kuuma ndi kulimba kwa diamondi?
Kuuma kumawonetsa kutengeka kwa chinthu ku zokanda. Mosiyana ndi izi, mphamvu kapena kulimba kumayesa kusatetezeka kwa chinthu kuti chitha kulephera. Choncho, diamondi ndizovuta kwambiri (kotero zimagwiritsidwa ntchito kukanda zipangizo zina popanda kusiya mikwingwirima), koma osati zamphamvu kwambiri - kotero zimatha kuthyoledwa ndi nyundo. (2)
