Yuav ua li cas kho cov cemented carbide tshwj xeeb-puab qhov?

Hauv peb lub neej niaj hnub, peb nyob ib puag ncig los ntawm ntau yam khoom siv hlau. Koj puas paub tias cov khoom uas tsis yog tus qauv tshwj xeeb zoo li cov cemented carbide yog tsim? Muaj ntau txoj hauv kev los ua cov hlau, tab sis txoj kev siv feem ntau yog txiav. Yog li yuav ua li cas tsim thiab ua cov cemented carbide tshwj xeeb-puab qhov?

Cia peb pib los ntawm kev saib cov txheej txheem tsim cov cemented carbide:

Ua ntej, tungsten carbide yog tov nrog cobalt los ua cov hmoov uas tuaj yeem muab faib ua cov khoom noj. Ncuav cov granular sib tov rau hauv pwm kab noj hniav thiab nias. Nws muaj qhov siv nruab nrab zoo li chalk. Tom ntej no, nias qhov khoob yog muab tso rau hauv lub qhov cub sintering thiab rhuab ntawm qhov kub ntawm txog 1400 ° C, ua rau cemented carbide.

Yog li yuav ua li cas peb ua qhov nyuaj carbide ib feem ntawm carbide?

1. Cov ntaub ntawv xav tau rau kev tsim cov cemented carbide tshwj xeeb-zoo li cov khoom yog nruj nreem sib xyaw, thiab cov sib tov tau txais feem ntau hu ua raw cov ntaub ntawv.

2. Cov khoom uas xav tau ntawm cemented carbide tshwj xeeb-puab cov khoom yog nqa tawm nyob rau hauv cov tsoos yas txhaj tshuaj molding tshuab. Nyob ntawm seb muaj pes tsawg leeg ntawm cov khoom siv hauv polymer matrix, cov khoom siv raw yog rhuab mus txog 100-240 ° C thiab tom qab ntawd nias rau hauv kab noj hniav ntawm qhov xav tau. Tom qab txias, lub molded ib feem yog ejected ntawm lub kab noj hniav thiab tshem tawm.

3. Tshem tawm cov nplaum los ntawm cov khoom molded. Kev khiav hauj lwm yuav tsum tau ua nyob rau hauv xws li ib txoj kev uas tsis muaj kab nrib pleb tsim nyob rau hauv cov khoom carbide profiled. Adhesives tuaj yeem raug tshem tawm ntawm ntau txoj kev. Lub binder feem ntau yog tshem tawm los ntawm tshav kub los yog los ntawm extraction nyob rau hauv ib tug haum hnyav los yog ib tug ua ke ntawm ob qho tib si.

4. Sintering yog ib txwm ua raws li cov cuab yeej nias qhov chaw.

Cov saum toj no yog txoj kev tsim cov cemented carbide tshwj xeeb-zoo li tus, yog tias koj xav tau kho tshwj xeeb-zoo li tus cemented carbide, koj tuaj yeem tiv tauj zhuzhou chuangrui cemented carbide Hoobkas txhua lub sijhawm. Peb cov khoom uas tsis yog tus qauv tshwj xeeb zoo li cemented carbide npog ntau yam khoom kom tau raws li cov kev xav tau ntawm cov neeg siv khoom hauv kev lag luam sib txawv.
