Kev tsim cov fwj iav yog ib qho txheej txheem nyuaj, thiab ntau yam ua rau muaj qhov tsis zoo uas ua rau qhov zoo ntawm cov khoom kawg tsis zoo. Kev nkag siab txog cov laj thawj no yog qhov tseem ceeb rau kev txhim kho cov qauv kev tsim khoom thiab xyuas kom meej tias cov fwj iav zoo. Nov yog qee qhov laj thawj feem ntau rau qhov tsis zoo hauv kev tsim cov fwj iav:
1. Tsis sib xws thaum lub sijhawm nkag mus rau pwm thawj zaug
Thaum lub khob iav tsis nkag mus rau hauv pwm thawj zaug, lossis yog tias phab ntsa pwm loj dhau, cov kab nrib pleb tuaj yeem tsim hauv lub raj mis. Thaum lub raj mis raug tshuab thiab ua kom zoo li qub, cov kab nrib pleb no tuaj yeem nthuav dav thiab loj hlob, ua rau pom qhov tsis zoo ntawm lub raj mis iav.
2. Cov Cim Txiav Los Ntawm Cov Tshuab Pub Noj
Yog tias lub cim txiab los ntawm lub tshuab pub sab saud loj dhau, nws tuaj yeem tso cov qhov txhab rau ntawm lub cev fwj. Cov qhov tsis zoo no feem ntau pom tseeb thiab tuaj yeem ua rau lub raj mis tsis zoo nkauj.
3. Cov Khoom Siv Moulding Tsis Zoo
Qhov zoo ntawm cov pwm pib thiab cov ntaub ntawv siv hauv cov txheej txheem molding ua lub luag haujlwm tseem ceeb. Yog tias qhov ceev ntawm cov pwm tsis txaus lossis yog tias oxidation tshwm sim sai dhau ntawm qhov kub siab, nws tuaj yeem tsim cov ntsiab lus concave ntawm qhov chaw pwm. Qhov no ua rau cov khoom kawg uas tsis muaj qhov tiav du thiab huv.
4. Tsis Siv Roj Rau Cov Pwm
Kev siv roj tsis tu ncua rau ntawm cov pwm fwj iav tuaj yeem ua rau tsis muaj roj txaus. Qhov no tuaj yeem ua rau muaj kev hloov pauv ntawm qhov nrawm thiab hom khoom siv, cuam tshuam tsis zoo rau cov txheej txheem pwm.
5. Tsim pwm tsis tsim nyog
Kev tsim pwm tsis zoo, txawm tias loj dhau lossis me dhau, tuaj yeem ua rau cov khoom faib tsis sib npaug thaum lub sijhawm tshuab. Yog tias cov khoom tsis puv lub qhov sib npaug, nws tuaj yeem tsim cov qhov tsis muaj zog thiab cov nplaim tsis sib npaug ntawm lub raj mis iav.
6. Kev Hloov Pauv ntawm Qhov Ceev ntawm Cov Khoom Uas Yuav Tso Tawm
Yog tias qhov ceev ntawm cov khoom poob tsis sib xws, lossis yog tias qhov chaw teeb tsa ntawm lub qhov cua tsis tsim nyog, nws tuaj yeem ua rau qhov kub tsis sib npaug hauv pwm pib. Qhov no tuaj yeem tsim cov chaw txias hauv lub khob, cuam tshuam tsis zoo rau qhov tiav thiab kev ua tiav ntawm lub raj mis.
7. Cov Khoom Tsis Zoo Hauv Cov Kua Iav
Qhov huv thiab qhov kub sib npaug ntawm cov kua iav hauv lub qhov cub yog qhov tseem ceeb heev. Cov kuab paug lossis qhov tsis sib xws tuaj yeem ua rau muaj npuas, cov khoom me me, thiab cov qhov tsis zoo hauv cov khoom kawg, ua rau nws tsis zoo.
8. Kev Hloov Pauv Ceev ntawm Tshuab
Kev siv cov tshuab ntawm qhov ceev uas ceev dhau los yog qeeb dhau yuav ua rau lub cev fwj iav tsis sib npaug. Qhov no tuaj yeem ua rau qhov sib txawv ntawm qhov tuab ntawm phab ntsa thiab cov qauv tsis zoo nkauj ntawm qhov chaw ntawm lub fwj.
Xaus lus
Yuav kom ntseeg tau tias cov fwj iav zoo, cov chaw tsim khoom yuav tsum daws cov teeb meem no los ntawm kev txhim kho lawv cov txheej txheem, tswj cov khoom siv, thiab siv cov ntaub ntawv zoo. Los ntawm kev nkag siab txog cov hauv paus ntawm cov teeb meem no, cov chaw tsim khoom tuaj yeem siv cov kev ntsuas tswj zoo dua thiab txhim kho cov txheej txheem tsim khoom tag nrho, ua rau cov fwj iav zoo nkauj dua thiab zoo nkauj dua.
