Kodi Ubwino wa Tungsten Carbide mu Zida Ndi Chiyani?

Monga tonse tikudziwa, tungsten carbide chuma amatchedwa "mano a mafakitale". Ili ndi kuuma kwakukulu kwambiri komanso kachulukidwe kakang'ono, komwe amagwiritsidwa ntchito kwambiri m'magawo odula, kubowola, ndi kupewa kuvala.

Wikipedia imalongosola tungsten carbide motere: “Tungsten carbide (chemical formula: WC) ndi mankhwala (makamaka carbide) okhala ndi magawo ofanana a tungsten ndi ma atomu a kaboni. M'mawonekedwe ake ofunikira, tungsten carbide ndi ufa wotuwa bwino, koma imatha kukanikizidwa ndikupangidwa kukhala mawonekedwe kudzera mu sintering kuti igwiritsidwe ntchito m'makina a mafakitale, zida zodulira, ma abrasives, zipolopolo zoboola zida, ndi zodzikongoletsera. Tungsten carbide ndi yolimba kuwirikiza kawiri kuposa chitsulo, yokhala ndi modulus ya Young pafupifupi 530-700 GPa, ndipo imachulukitsa kachulukidwe kachitsulo kawiri-pafupifupi pakati pa lead ndi golide. Imafanana ndi corundum (α-Al2O3) mu kuuma ndipo imatha kupukutidwa ndikumalizidwa ndi ma abrasives olimba kwambiri monga kiyubiki boron nitride ndi ufa wa diamondi, mawilo, ndi mankhwala.

Zinthu za Tungsten carbide zili ndi magwiridwe antchito apamwamba kwambiri. Kodi ubwino ndi chiyani pamene tungsten carbide ikugwiritsidwa ntchito m'munda wa zida?

1. Kuuma kwakukulu. Kuuma kwa tungsten carbide kumasiyanasiyana kuchokera ku 83HRA mpaka 94HRA. Kuuma kwakukulu kumapangitsa tungsten carbide kuvala mpaka nthawi 100 kuposa chitsulo mumikhalidwe kuphatikiza abrasion, kukokoloka, ndi ndulu. Kukana kuvala kwa tungsten carbide kuli bwino kuposa zitsulo zolimbana ndi kuvala.

2. Kukana kutentha ndi okosijeni. Kuti apange tungsten carbide, zinthu za carbide zimayikidwa mu ng'anjo pa kutentha kwakukulu kwa pafupifupi 1400 centigrade. Ma tungsten-base carbides amachita bwino mpaka pafupifupi 1000 ° F m'malo oxidizing ndi 1500 ° F m'malo osakhala oxidizing.

3. Dimensional Kukhazikika. Tungsten carbide sisintha gawo lililonse pakutentha ndi kuziziritsa ndipo imasunga kukhazikika kwake mpaka kalekale. Palibe kutentha kofunikira.

4. Pamwamba Amatha. Mapeto a gawo la as-sintered adzakhala pafupifupi 50 mainchesi. Pamwamba, cylindrical kapena kugaya mkati ndi gudumu la diamondi kutulutsa mainchesi 18 kapena kupitilira apo ndipo kumatha kutulutsa mainchesi 4 mpaka 8. Kupukutira kwa diamondi ndi kukweza kumatha kutulutsa mainchesi awiri ang'onoang'ono komanso kupukuta kotsika ngati 1/2 inchi yaying'ono.

Zhuzhou Better Tungsten Carbide Company ndi katswiri wopereka ma tungsten carbide. Tungsten carbide molds ndi tungsten carbide dies ndi amodzi mwa ogulitsa kwambiri. ZZbetter imatha kupanga mutu wozizira wa tungsten carbide umafa, tungsten carbide yowotcha imafa, zojambula za tungsten carbide zimafa, ndipo msomali wa tungsten carbide umafa. Pamwambapa amafa chimagwiritsidwa ntchito m'mafakitale ambiri ndi m'malo zitsulo kukhala kusankha pamwamba pa tooling ntchito. Ndi kuuma kwakukulu, kukana kuvala kwambiri, mphamvu yopindika kwambiri, komanso kugwira ntchito mokhazikika pamatenthedwe apamwamba komanso otsika, tsopano kugwiritsa ntchito tungsten carbide ndikokulirapo kuposa kale. Kampani yathu ipitiliza kupereka mayankho apamwamba kwambiri a carbide kwa makasitomala athu komanso makasitomala omwe angakhale nawo ndi chiyembekezo kuti carbide yathu ingawathandize kukwaniritsa mtengo wawo!

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.
