Tungsten Carbide Pob

2870℃yog lub melting point, 6000℃yog lub boiling point, thiab 15.63℃(18 degree) yog tus txheeb ze ntom. Nyob rau hauv nitric acid-hydrofluoric acid sib xyaw acid, tungsten carbide yog yooj yim soluble, thaum nws yog insoluble nyob rau hauv dej, hydrochloric acid, thiab sulfuric acid. Tungsten carbide nyob rau hauv daim ntawv ntshiab yog nkig. Ib qho ntxiv me ntsis ntawm cobalt, titanium, thiab lwm yam hlau tuaj yeem txo qhov brittleness. Txhawm rau kom tawg tsis kam, tantalum carbide, titanium carbide, lossis lawv cov kev sib xyaw ua ke yog nquag ntxiv rau tungsten carbide, uas yog siv los txiav hlau. Chemically, tungsten carbide yog ruaj khov. Tungsten carbide tseem hu ua interstitial (los yog insertion) compound vim cov pa roj carbon atoms tau ntxig rau hauv cov tungsten hlau lattice qhov khoob uas tsis ua rau cov khoom qub hlau lattice.Los ntawm cua sov lub tungsten thiab carbon sib tov kom kub, tungsten carbide tuaj yeem tsim. Cov tshuaj tiv thaiv tuaj yeem nrawm los ntawm qhov muaj hydrocarbons lossis hydrogen. Txhawm rau kom tshem tawm cov pa roj carbon monoxide, cov kauj ruam kawg hauv kev npaj rau cov tebchaw uas muaj tungsten oxygen yuav tsum tau kho lub tshuab nqus tsev ntawm 1500 degree. Tungsten carbide tuaj yeem siv rau ntawm qhov kub thiab txias thiab siv rau hauv kev tsim cov cuab yeej txiav, cov khoom siv hluav taws xob, roj turbines, dav hlau cav, nozzles, thiab lwm yam. Tungsten carbide yog lwm tungsten thiab carbon compound. Nws tus txheeb ze ceev yog 17.15, nws melting thiab boiling ntsiab lus yog 2860℃thiab 6000 degree, feem. Nws cov qauv tshuaj yog W2C. Nws yog zoo tib yam rau carbide tungsten steel, los yog cemented carbide, nyob rau hauv cov nqe lus ntawm nws cov yam ntxwv, manufacturing txheej txheem, thiab daim ntaub ntawv.Qhov tsuas yog cov khoom nyuaj tshaj nws yog pob zeb diamond. Nws muaj cov yam ntxwv tshuaj ruaj khov. Nws tsis hnov ​​​​mob nrog sulfuric acid, hydrochloric acid, lossis txawm tias aqua regia thaum rhuab. Nws yuav tsis yaj thiab. Tungsten muaj cov thermal ua haujlwm siab heev. Vim nws qhov siab melting point ntawm 3410 degree, nws yog suav hais tias yog cov hlau insoluble tshaj plaws nyob rau hauv cov xwm. Ntawm tag nrho cov hlau, nws muaj qee qhov zoo tshaj plaws hardness. Tsuas yog nyob rau qhov kub siab heev nws tuaj yeem compressed. Tungsten carbide pob yog nquag siv hauv dej thiab ntws ntsuas, cwj mem tsim, thiab lwm yam lag luam.

Cov txheej txheem tsim khoom ntawm tungsten carbide pob zoo ib yam li lwm cov khoom siv cemented carbide:

Powder → Formula raws li daim ntawv thov → ntub sib tsoo → Sib tov → Crushing → Qhuav → Sieving → Tom qab ntawd ntxiv molding tus neeg sawv cev → Qhuav dua → Sieve los npaj cov sib tov → Granulation → Txias isostatic nias → Molding → Sintering → Forming (blank) → ntim .

Raws li cov kev cai siv tshwj xeeb thiab cov tsis muaj feem cuam tshuam, feem ntau yog cemented carbide npas, tungsten steel npas, tungsten cov khoom, siab tshwj xeeb gravity alloy npas thiab lwm yam carbide spherical khoom.

 

 

 

 

Tungsten carbide pob muaj ntau yam kev siv, xws li:

 

pob ntsia hlau, inertial navigation systems, precision qhov punched thiab ncab, precision bearings, ntsuas, ntsuas, cwj mem ua, tshuaj tsuag tshuab, dej nres, sealing li qub, mechanical Cheebtsam, thiab twj siab -cov cuab yeej nuv ntses zoo, counterweights, xov, hydrochloric acid labs, xuas nrig ntaus qhov, roj teb, twj, thiab lwm yam lag luam.

 

 

Txheem export ntim, feem ntau peb pob:

1.Moisture -cov ntaub ntawv pov thawj

2. Tiv thaiv kev ntim khoom sib tsoo

3.Export ntoo thawv sab nraum

Peb yuav muab kev nthuav qhia, huab cua, thiab kev thauj mus los hauv av uas ceev tshaj plaws, nyab xeeb tshaj plaws, thiab nyab xeeb tshaj plaws rau koj.
