1. Thaum lub sij hawm siv aluminium alloy qhov rooj thiab qhov rais, qhov kev txiav txim yuav tsum yog lub teeb, thiab lub laub thiab rub yuav tsum mus nrog qhov ntws; yog tias muaj teeb meem, tsis txhob thawb nyuaj, thiab teeb meem ua ntej. Plua plav thiab deformation yog cov laj thawj tseem ceeb rau kev nyuaj ntawm kev ua tshiab aluminium alloy qhov rooj thiab qhov rais. Nws yog ib qho tsim nyog yuav tsum ua kom lub qhov rooj huv si, tshwj xeeb tshaj yog kev ntxuav ntawm zawv zawg zawj. Cov plua plav nyob hauv qhov zawj thiab sab saum toj ntawm lub qhov rooj foob tuaj yeem raug tshem tawm nrog lub tshuab nqus tsev.
2. Thaum ntxuav aluminium alloy qhov rooj thiab qhov rais, cov neeg yuav tsum tsis txhob nqis los ntawm aluminium ncej los yog rub lub thav duab rau kev txhawb nqa.
3. Aluminium alloy qhov rooj thiab qhov rais tuaj yeem dipped hauv dej huv los yog cov tshuaj ntxuav tes nrog cov ntaub mos muag. Tsis txhob siv cov xab npum zoo tib yam thiab ntxuav cov hmoov, thiab tsis txhob siv cov tshuaj detergents xws li decontamination hmoov thiab xab npum ntxhua khaub ncaws uas muaj zog acid thiab alkali.
4. Tom qab hnub los nag, cov iav ntub dej thiab lub qhov rooj thiab qhov rais thav duab yuav tsum tau muab so kom qhuav nyob rau lub sijhawm, thiab kev saib xyuas tshwj xeeb yuav tsum tau them nyiaj kom qhuav cov dej hauv chute. Lub chute yog siv rau lub sijhawm ntev thiab kev sib txhuam quab yuam, koj tuaj yeem ntxiv cov roj me me los yog siv cov roj paraffin.
5. Qhov kev sib txuas ntawm aluminium alloy thav duab yuav tsum tau kuaj xyuas ntau zaus, cov bolts yuav tsum tau nruj rau lub sijhawm, thiab cov khoom puas yuav tsum tau hloov. Qhov chaw tsis zoo ntawm aluminium alloy qhov rooj thiab qhov rais xws li tso cov ncej pins, cua braces, thiab hauv pem teb springs yuav tsum tau xyuas ntau zaus, thiab lubricating roj yuav tsum tau ntxiv tsis tu ncua kom lawv huv si thiab hloov tau.
6. Lub sealing tops thiab iav seals yog cov qauv tseem ceeb los xyuas kom meej lub sealing thiab rwb thaiv tsev ntawm lub qhov rooj thiab qhov rais. Yog tias lawv poob, lawv yuav tsum tau kho thiab hloov raws sijhawm.
7. Nco ntsoov xyuas qhov sib koom ua ke ntawm aluminium alloy ncej thiab phab ntsa. Yog tias nws xoob dhau sijhawm, nws yooj yim rau deform lub thav duab tag nrho, kom lub qhov rooj thiab qhov rais tsis tuaj yeem kaw thiab kaw. Yog li ntawd, cov xoob screws ntawm kev sib txuas yuav tsum tau nruj tam sim ntawd. Yog tias cov ntsia hlau hauv qab xoob, lawv yuav tsum tau muab khi nrog epoxy super kua nplaum thiab me me ntawm cov cement.
