Ua tib zoo saib xyuas qhov teeb meem ntawm cov dej phwj tuaj hauv kev tsim cov iav cawv fwj

Txoj Kev Txau Zoo Tshaj Plaws thiab Cov Txheej Txheem rau Xim Txau Cov iav Wine Fwj
Cov kab ntau lawm feem ntau muaj cov tshuaj tsuag lub rooj muag khoom, cov saw txuas thiab lub qhov cub. Kuj tseem muaj kev kho dej pem hauv ntej ntawm iav cawv fwj, thiab kev saib xyuas tshwj xeeb ntawm iav wine fwj yog qhov teeb meem ntawm cov dej phwj tuaj. Raws li qhov zoo ntawm cov tshuaj tsuag, nws muaj feem xyuam rau kev kho dej, qhov chaw tu ntawm lub workpiece, conductivity ntawm tus nuv, qhov loj ntawm huab cua ntim, tus nqi ntawm cov hmoov txau, thiab theem ntawm tus neeg teb xov tooj. Nws raug nquahu kom sim cov txheej txheem hauv qab no:
1. Ntu ua ntej ua ntej. Cov kev kho mob ua ntej muaj xws li pre-stripping, lub ntsiab stripping, deg conditioning, thiab lwm yam. Yog hais tias nws yog nyob rau hauv sab qaum teb, qhov kub ntawm lub ntsiab stripping yuav tsum tsis txhob qis heev, thiab yuav tsum tau khaws cia kub. Txwv tsis pub, cov nyhuv kho yuav tsis zoo;
2. Preheating seem. Tom qab pretreatment, nws yuav nkag mus rau hauv preheating seem, uas feem ntau yuav siv sij hawm 8-10 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 cov hmoov txau hauv chav, thiaj li ua kom cov adhesion ntawm cov hmoov;
3. 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 rau ntawm lub workpiece, yuav muaj ntau yam ntawm cov khoom ua haujlwm, uas yuav txo qhov zoo; 4. Cov hmoov txau seem. Qhov tseem ceeb tshaj plaws nyob rau hauv seem no yog qhov teeb meem ntawm cov hmoov txau tus tswv. Yog tias koj xav tsim cov khoom zoo, nws tseem kim heev los siv nyiaj los ntiav tus kws tshaj lij; 5. Ntu ntu kom qhuav. Dab tsi yuav tsum tau them rau hauv ntu no yog qhov kub thiab txias lub sijhawm ci. Cov hmoov feem ntau yog 180-200 degrees, nyob ntawm seb cov khoom ntawm lub workpiece. Tsis tas li ntawd, lub tshuab ziab khaub ncaws yuav tsum tsis txhob nyob deb dhau ntawm chav tsev ntxhua khaub ncaws, feem ntau 6 meters zoo dua.
