Kupanga Tungsten Carbide Powder

Tungsten carbide powder ndiye chinthu chachikulu chopangira tungsten carbide. Zinthu zina zitha kugula tungsten carbide ufa mwachindunji, ndipo zina zitha kubwezanso kuchokera kwa ena. Tungsten carbide ufa sapezeka mwachindunji mu chilengedwe. Amapangidwa ndi ndondomeko zingapo. M'nkhaniyi, kupanga tungsten carbide ufa kudzakhala chidziwitso chachidule.

Kupanga

Tungsten carbide ili ndi kuchuluka kwa tungsten ndi kaboni. Kuti apange tungsten carbide, tungsten trioxide iyenera kukhala ndi hydrogenated ndi kuchepetsedwa poyamba. Pochita izi, titha kupeza ufa wa tungsten ndi madzi amadzimadzi. Kenako tungsten ufa ndi kaboni adzapanikizidwa pansi pa kukakamizidwa kwakunja pamlingo wofanana wa mole. Chotsekeracho chidzayikidwa pa graphite poto ndikutenthedwa kupitirira 1400 ℃ mu ng'anjo yolowera ndi mtsinje wa haidrojeni. Ndi kuwonjezeka kwa kutentha, ma moles awiri a tungsten amachitira ndi 1mole ya carbon ndi kupanga W2C. Ndiyeno tungsten yofanana ndi carbon idzachitapo ndipo tungsten carbide idzapangidwa. Zomwe zimachitika m'mbuyomu zimachitika kale kuposa zomalizazi chifukwa kutentha kwa zomwe zidachitika kale ndizotsika. Pakadali pano, pali W, W2C, ndi WC wambiri omwe alipo mu ng'anjo. Adzachita pansi pa kutentha kwakukulu. Pambuyo pomaliza, titha kupeza tungsten carbide powder.

The main chemical reaction ndi motere:

WO3 + 3H2 → W + 3H2O

2W + C = W2C

W + C = WC

Kusungirako

Tungsten carbide ufa ndi bwino kusungidwa mu vacuum kulongedza ndikusungidwa m'chipinda chozizira komanso chowuma.

Kugwiritsa ntchito

Tungsten carbide ufa amagwiritsidwa ntchito popanga zinthu za tungsten carbide. Tungsten carbide ufa, wosakanikirana ndi gawo lina la zomangira, amawumbidwa ndikuyikidwa muzinthu zosiyanasiyana za tungsten carbide kuti azigwiritsidwa ntchito mosiyanasiyana. Tungsten carbide ufa amatha kupangidwa kukhala mabatani a tungsten carbide kuti agwiritse ntchito migodi, ma tungsten carbide studs a HPGR, ndodo za tungsten carbide zopangira mphero, ndi tungsten carbide burr kudula ndi mphero zina.

Kuchokera m'nkhaniyi, tikhoza kudziwa kupanga tungsten carbide powder, zomwe ndi zopangira zinthu zambiri za tungsten carbide ndi tungsten alloys. Chifukwa chake kusunga moyenera tungsten carbide ufa ndikofunikira kuwonetsetsa kuti zinthu za tungsten carbide zimatha kusunga machitidwe awo.

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.
