Mitundu yosiyanasiyana ya Carbides

Ngakhale tungsten carbide imagwira ntchito yofunika kwambiri pamsika wamafakitale, ma carbides ena ambiri amapezeka m'mafakitale osiyanasiyana. M'nkhaniyi, mudziwa mitundu yosiyanasiyana ya ma carbides. Ali:

1. Boron carbide;

2. Silicon carbide;

3. Tungsten carbide;

Boron carbide

Boron carbide ndi gulu la crystalline la boron ndi carbon. Ndi mtundu wa zinthu zopangidwa mopangidwa ndi kuuma kwakukulu kotero kuti zitha kugwiritsidwa ntchito kwambiri pazinthu zotayirira komanso zosavala, zopepuka zophatikizika, komanso zitha kugwiritsidwa ntchito pakuwongolera ndodo zopangira magetsi a nyukiliya.

Monga zinthu zamakampani, boron carbide ili ndi zinthu zambiri. Ili ndi kuuma kwa Mohs kwa 9 mpaka 10, komanso ndi imodzi mwa zida zolimba kwambiri. Ndi kuuma kwakukulu kotereku komanso kutsika kochepa, boron carbide ingagwiritsidwe ntchito ngati kulimbikitsa kwa aluminiyumu kunkhondo. Kukana kwake kuvala kwambiri kunapangitsa kuti azitha kupeza ntchito ngati zida zophulika zophulika ndi zisindikizo zapampu. Boron carbide angagwiritsidwe ntchito ngati abrasive mu mawonekedwe ufa mu bwino abrading zitsulo ndi ceramic mankhwala. Komabe, ndi kutentha kochepa kwa okosijeni wa 400-500 ° C, boron carbide imalephera kupirira kutentha kwa zitsulo zolimba zolimba.

Silicon carbide

Silicon carbide ndi gulu la crystalline la silicon ndi kaboni. Anapezeka mu 1891 ndi woyambitsa wa ku America. Kenako silicon carbide imagwiritsidwa ntchito ngati zinthu zofunika pa sandpaper, mawilo opera, ndi zida zodulira. Osati mpaka makampani amakono a silicon carbide atapezeka kuti amagwiritsidwa ntchito m'magawo osagwirizana ndi mapampu komanso ngakhale injini za rocket, ndi zina zotero.

Asanatulukire boron carbide, silicon carbide inali chinthu chovuta kwambiri. Ilinso ndi mawonekedwe a fracture, high matenthedwe madutsidwe mphamvu, mkulu-kutentha mphamvu, otsika matenthedwe kufutukuka, ndi kukana zochita mankhwala.

Tungsten carbide

Tungsten carbide ndi chida chodziwika kwambiri m'makampani amakono, omwe amakhala ndi tungsten carbide ufa ndi kuchuluka kwa cobalt kapena faifi tambala monga chomangira. Tungsten carbide ndi chinthu chokhuthala mu imvi yowala. Ndizosiyana kusungunuka ndi malo osungunuka kwambiri. Tungsten carbide imakhala ndi kuuma kwakukulu, kukana kuvala, kukana kukhudzidwa, kukana kugwedezeka, ndi mphamvu ndipo imatha kugwira ntchito kwa nthawi yayitali. Ndipo tungsten carbide imatha kupangidwa mosiyanasiyana ndi mitundu yazinthu zamtundu wa tungsten carbide, monga mabatani a tungsten carbide, zoyikapo za tungsten carbide, ndodo za tungsten carbide, zingwe za tungsten carbide, mipira ya tungsten carbide, ma valve a tungsten carbide, ndi zikhomo za tungsten carbide. Amagwiritsidwa ntchito kwambiri m'mafakitale amakono, monga migodi, gasi, mafuta, kudula, kupanga, kulamulira madzi, ndi zina zotero.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
