Cov kab ntau lawm rau cov iav cawv fwj feem ntau muaj cov tshuaj tsuag lub rooj muag khoom, cov hlua dai thiab qhov cub.Cov iav fwj thiab kev kho dej pem hauv ntej, iav fwj xav tau kev saib xyuas tshwj xeeb rau cov 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, kev tu qhov chaw ntawm lub workpiece, hluav taws xob 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 xaiv cov hauv qab no los sim:
1. Ua ntej ua ntu.Qhov kev kho mob ua ntej ntawm cov khoom siv iav iav lub raj mis txau muaj xws li ua ntej stripping, lub ntsiab stripping, kev kho qhov chaw, thiab lwm yam. Yog tias nws nyob rau sab qaum teb, qhov kub ntawm lub ntsiab stripping yuav tsum tsis txhob qis dhau, thiab nws yuav tsum tau khaws cia. sov.Txwv tsis pub, cov nyhuv ua tsis zoo;
2. Preheat seem.Tom qab pretreatment, nws yuav nkag mus rau hauv preheating seem, uas feem ntau yuav siv sij hawm 8 mus rau 10 feeb.Thaum lub khob lub raj mis mus txog rau hauv cov hmoov txau, cov tshuaj txau yuav tsum muaj qee qhov seem ntawm cov cua sov kom nce qhov adhesion ntawm cov hmoov;
3. Iav wine raj mis soot tshuab purification seem.Yog hais tias tus txheej txheem yuav tsum tau sib piv ntawm lub workpiece yuav tsum tau txau yog heev siab, seem no yog qhov tseem ceeb, txwv tsis pub, yog hais tias muaj ntau cov plua plav adsorbed ntawm lub workpiece, lub nto ntawm lub workpiece tom qab ua tiav yuav muaj ib tug ntau ntawm hais. txo qhov zoo;
4. Hmoov txau seem.Lub raj mis iav yog lub thawv ntim khoom haus ib txwm nyob hauv kuv lub tebchaws, thiab iav kuj yog cov khoom ntim keeb kwm heev.Nrog ntau hom ntim cov ntaub ntawv dej nyab mus rau hauv kev ua lag luam, cov thawv iav tseem tuav txoj haujlwm tseem ceeb hauv kev ntim cov dej haus, uas yog cais tsis tau los ntawm nws cov yam ntxwv ntim uas tsis tuaj yeem hloov los ntawm lwm cov khoom ntim.Tus yuam sij rau ntu no yog qhov teeb meem kev ua haujlwm ntawm cov hmoov txau tus tswv.Yog tias koj xav tsim cov khoom zoo, nws tseem tsim nyog siv nyiaj rau tus kws tshaj lij.
5. Qhuav ntu.Dab tsi yuav tsum tau them sai sai rau hauv ntu no yog qhov kub thiab txias lub sijhawm ci (piav qhia: ci khoom nrog cov khoom siv hluav taws kub), thiab 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 cov hmoov txau, feem ntau 6 meters.
Kev noj zaub mov ntev ntev ntawm cov khoom noj uas muaj polyethylene molecules yuav ua rau kiv taub hau, mob taub hau, xeev siab, tsis qab los noj mov, tsis nco qab, thiab lwm yam, thiab txawm tias ntshav ntshav.Yog li ntawd, kev siv lub raj mis yas rau seasoning yog teeb meem rau tib neeg noj qab haus huv yam tsis muaj txiaj ntsig.
Hauv tsev neeg, iav fwj tuaj yeem siv los hloov lub raj mis yas los tuav cov khoom noj thiab lwm yam.Ua tib zoo saib xyuas tshwj xeeb thaum siv lub raj mis yas, tsis txhob kov cov kua txiv hmab txiv ntoo, tshuaj ntxuav tes, thiab lwm yam, tsis txhob raug tshav ntuj ncaj qha, kub kub, thiab lwm yam., kom tsis txhob muaj tshuaj lom neeg.
Tsis tas li ntawd, thaum koj yuav cov tais diav yas, koj yuav tsum xaiv cov khoom yas nrog PE (polyethylene) lossis PP (polypropylene) cov ntawv, ob peb cov qauv zoo nkauj, tsis muaj xim thiab tsis muaj ntxhiab, thiab du nto.
