Tungsten Carbide
Kufotokozera
Tungsten carbide ndi kristalo wakuda wa hexagonal wokhala ndi zitsulo zonyezimira, ndipo kuuma kwake kumafanana ndi diamondi. Ndi kondakitala wabwino wa magetsi ndi kutentha. Zakhala zikugwiritsidwa ntchito kwambiri popanga zida zodulira mwachangu kwambiri, zida zamapangidwe amoto, zida za injini ya jet, ma cermets ndi zinthu zotenthetsera kukana, etc.Pure tungsten carbide ndi yolimba ndipo imatha kuchepetsa kuphulika ngati zitsulo zazing'ono monga titaniyamu ndi cobalt zili. Zowonjezera.Monga chida cholimba kwambiri komanso kuvala zinthu zosagwirizana, zimatha kupanga njira yolimba yokhala ndi ma carbides ambiri.WC-TiC -Co cemented carbide zida zakhala zikugwiritsidwa ntchito kwambiri.Itha kugwiritsidwanso ntchito ngati chowonjezera chosinthidwa cha NbC-C ndi TaC-C ternary system carbides, zomwe sizingangochepetsa kutentha kwa sintering, komanso kukhalabe ndi magwiridwe antchito abwino kwambiri ndipo zitha kugwiritsidwa ntchito ngati zida zamlengalenga.
Kugwiritsa ntchito
Hard alloy, resistance heat element, cermet etc

Chofunika chapadera cha kukula ndi mankhwala akhoza kupangidwa |
Chifukwa Chosankha Ife:
1. Mutha kupeza zinthu zabwino kwambiri malinga ndi zomwe mukufuna pamtengo wotsika kwambiri.
2. Timaperekanso Reworks, FOB, CFR, CIF, ndi mitengo yobweretsera khomo ndi khomo. Tikukulangizani kuti mugwiritse ntchito zotumiza zomwe zingakhale zotsika mtengo.
3. Zipangizo zomwe timapereka ndizotsimikizika kotheratu, kuyambira pa satifiketi yoyeserera mpaka pagawo lomaliza.
4. e chitsimikizo kupereka yankho mkati 24hours(nthawi zambiri mu ola lomwelo)
5. Mutha kupeza njira zina zogulitsira, zoperekera mphero ndikuchepetsa nthawi yopanga.
6. Ndife odzipereka kwathunthu kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zomwe mukufuna mutapenda zonse zomwe mungasankhe, sitidzakusocheretsani popanga malonjezo abodza omwe angapangitse ubale wabwino ndi makasitomala.
Chitsimikizo cha Ubwino (kuphatikiza zonse Zowononga ndi Zosawononga)
1. Mayeso a Visual Dimension
2. Kuwunika kwamakina monga kukhazikika, kutalika ndi kuchepetsa dera.
3. Kusanthula zotsatira
4. Kusanthula kwa mankhwala
