Txawv Carbides

Txawm hais tias tungsten carbide ua lub luag haujlwm tseem ceeb hauv kev lag luam kev lag luam, ntau lwm cov carbide muaj nyob hauv ntau yam lag luam. Hauv kab lus no, koj yuav paub ntau hom carbides. Lawv yog:

1. Boron carbide;

2. Silicon carbide;

3. Tungsten carbide;

Boron carbide

Boron carbide yog crystalline compound ntawm boron thiab carbon. Nws yog ib yam ntawm cov khoom siv hluavtaws uas muaj siab hardness kom nws tuaj yeem siv dav hauv cov khoom siv abrasive thiab hnav-resistant, cov ntaub ntawv sib xyaw, thiab tuaj yeem siv rau hauv kev tswj cov pas nrig rau kev tsim hluav taws xob nuclear.

Raws li cov khoom lag luam, boron carbide muaj ntau yam khoom. Nws muaj Mohs hardness ntawm 9 txog 10, thiab nws kuj yog ib qho ntawm cov khoom siv nyuaj tshaj plaws. Nrog xws li ib tug siab hardness thiab tsawg ceev, boron carbide yuav siv tau raws li ib tug reinforcing neeg sawv cev rau txhuas nyob rau hauv cov tub rog. Nws qhov hnav tsis kam ua rau nws tuaj yeem nrhiav tau daim ntawv thov raws li cov khoom siv ntawm abrasive blasting nozzles thiab twj tso kua mis seals. Boron carbide tuaj yeem siv los ua cov tshuaj abrasive hauv cov hmoov hauv cov khoom zoo ntawm cov hlau thiab cov khoom siv ceramic. Txawm li cas los xij, nrog oxidation qis ntawm 400-500 ° C, boron carbide tsis tuaj yeem tiv taus qhov kub ntawm kev sib tsoo cov cuab yeej hardened.

Silicon carbide

Silicon carbide yog crystalline compound ntawm silicon thiab carbon. Nws tau pom nyob rau hauv 1891 los ntawm ib tug American inventor. Tom qab ntawd silicon carbide yog siv los ua cov khoom tseem ceeb rau cov ntawv xuab zeb, sib tsoo lub log, thiab cov cuab yeej txiav. Tsis txog thaum niaj hnub kev lag luam silicon carbide pom tau siv nyob rau hauv hnav-tiv taus qhov chaw rau cov twj thiab txawm foob pob ua ntxaij cav, thiab hais txog.

Ua ntej kev tshawb pom ntawm boron carbide, silicon carbide yog cov khoom siv nyuaj tshaj plaws. Nws kuj muaj cov yam ntxwv tawg, siab thermal conductivity, siab kub lub zog, tsis tshua muaj thermal expansion, thiab tsis kam mus rau cov tshuaj tiv thaiv.

Tungsten carbide

tungsten carbide yog cov khoom siv nrov tshaj plaws hauv kev lag luam niaj hnub no, uas muaj tungsten carbide hmoov thiab qee qhov nyiaj cobalt lossis npib tsib xee hmoov ua cov ntaub ntawv. Tungsten carbide yog cov khoom ntom ntom hauv lub teeb grey. Nws yog qhov sib txawv rau yaj nrog lub siab melting point. Tungsten carbide muaj zog hardness, hnav tsis kam, cuam tshuam tsis kam, poob siab tsis kam, thiab lub zog thiab tuaj yeem ua haujlwm ntev. Thiab tungsten carbide tuaj yeem tsim rau hauv cov duab sib txawv thiab ntau hom tungsten carbide cov khoom, xws li tungsten carbide nyees khawm, tungsten carbide inserts, tungsten carbide rods, tungsten carbide strips, tungsten carbide balls, tungsten carbide pins, tungsten carbide li qub. Lawv tau siv dav hauv kev lag luam niaj hnub, xws li mining, roj, roj, txiav, kev tsim khoom, tswj cov kua dej, thiab lwm yam.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
