Cov kauj ruam ntawm cov xim dawb wine fwj tau muab faib ua ob peb txheej txheem xws li tshuaj tsuag, txhuam hniav, thiab ntub dej.
Txau txuas ntxiv: 15 feeb / 25 degrees tom qab thawj txheej ntawm cov tshuaj tsuag (ntiv tes kov cov txheej hauv qab tsis nplaum), koj tuaj yeem txau cov txheej thib ob Lub sij hawm ziab: nto qhuav: 15 feeb / 25 degrees, tawv qhuav: 12 teev / 25 degrees, ci ci: 30 feeb / 80 degrees Adhesion: thawj-chav kawm txheej hardness: 3-5H dej tsis kam: ntev ntsev tsuag tshuaj tiv thaiv: 72 teev los ntawm tus qauv ntsuas GB1771-(88)
Huab cua tsis kam: 120 teev los ntawm kev kuaj kev laus tshuab
Cov txheej txheem iav fwj tsim feem ntau suav nrog:
① Raw khoom ua ntej. Sib tsoo cov khoom siv raw (quartz xuab zeb, dej qab zib tshauv, limestone, feldspar, thiab lwm yam), qhuav ntub cov ntaub ntawv raw, thiab tshem tawm cov hlau los ntawm cov hlau uas muaj cov khoom siv raw los xyuas kom cov iav zoo.
② Batch khoom npaj.
③ Qhuav.
Cov khoom siv iav batch yog rhuab ntawm qhov kub siab (1550 ~ 1600 degrees) nyob rau hauv lub pas dej ua ke kiln los yog lub pas dej rauv taws los ua ib tug uniform, npuas-dawb kua iav uas ua tau raws li qhov yuav tsum tau molding.
④ Kev tsim kho.
Muab cov iav ua kua rau hauv pwm los ua cov khoom siv iav ntawm cov duab uas yuav tsum tau ua, xws li cov phaj tiaj tiaj, ntau yam khoom siv, thiab lwm yam.
⑤ Kev kho cua sov.
Los ntawm annealing, quenching thiab lwm yam txheej txheem, tshem tawm los yog ua kom muaj kev ntxhov siab, theem kev sib cais los yog crystallization hauv iav, thiab hloov cov txheej txheem ntawm lub khob. Lub raj mis txau cov txheej txheem Cov iav lub raj mis txau cov kab ntau lawm feem ntau muaj lub rooj muag tshuaj tsuag, cov saw txuas thiab lub qhov cub. Kuj tseem muaj kev kho dej pem hauv ntej ntawm iav fwj. Cov iav fwj yuav tsum tau them nyiaj tshwj xeeb rau qhov teeb meem ntawm cov dej phwj tuaj. Raws li qhov zoo ntawm cov iav fwj tshuaj tsuag, nws muaj feem xyuam rau kev kho dej, qhov chaw tu ntawm workpieces, hluav taws xob conductivity ntawm hooks, qhov loj ntawm huab cua ntim, npaum li cas ntawm cov hmoov txau, thiab theem ntawm cov neeg ua haujlwm.
Nws raug nquahu kom xaiv cov hauv qab no los sim:
1. Pre-treatment seem Cov txheej txheem ua ntej ntawm cov iav fwj tshuaj tsuag muaj xws li ua ntej stripping, lub ntsiab stripping, kev kho deg, thiab lwm yam. Yog tias nws nyob rau sab qaum teb, qhov kub ntawm lub ntsiab stripping yuav tsum tsis txhob qis dhau, thiab cua sov. yuav tsum khaws cia. Txwv tsis pub, cov nyhuv kho tsis zoo;
2. Tom qab kev kho mob ua ntej hauv ntu preheating, nws yuav nkag mus rau hauv ntu preheating, uas feem ntau siv 8 mus rau 10 feeb. Nws yog qhov zoo tshaj plaws los ua kom cov tshuaj txau ua haujlwm muaj qee qhov seem ntawm cov cua sov thaum lub khob iav mus txog chav tsev tshuaj tsuag hmoov, thiaj li ua kom cov adhesion ntawm cov hmoov. ;
3. Cov iav lub raj mis soot tshuab purification seem Yog tias cov txheej txheem yuav tsum tau ua ntawm cov tshuaj txau ua haujlwm yog qhov siab, ntu no yog qhov tseem ceeb, txwv tsis pub yog tias muaj ntau cov plua plav adsorbed ntawm lub workpiece, qhov saum npoo ntawm cov khoom ua haujlwm yuav muaj ntau yam, uas. yuav txo qhov zoo;
4. Powder spraying seem Qhov tseem ceeb tshaj plaws nyob rau hauv seem no yog cov teeb meem kev siv tshuaj tsuag tus tswv. Yog tias koj xav tsim cov khoom zoo, nws tseem kim heev los siv nyiaj los ntiav tus kws tshaj lij.
5. Kev ziab kom qhuav Qhov kub thiab lub sij hawm ci yuav tsum tau them sai sai rau hauv seem no. Feem ntau, 180 ~ 200 degrees rau hmoov yog zoo dua, nyob ntawm seb cov khoom ntawm lub workpiece.
