1. Kev Xaiv Khoom Siv

Kauj ruam thawj zaug hauv cov txheej txheem tsim khoom yog xaiv cov khoom siv tsim nyog. Cov chaw tsim khoom yuav tsum xav txog cov yam xws li qhov hnyav, tus nqi, kev cuam tshuam rau ib puag ncig, thiab kev ua raws li txoj cai. Thaum xaiv cov khoom siv lawm, nws yuav tau los ntawm cov neeg muag khoom thiab npaj rau kev tsim khoom.

 

2. Yaj thiab Casting

Rau cov hlau log hnyav, kauj ruam tom ntej yog yaj cov khoom xaiv. Cov txheej txheem no feem ntau tshwm sim hauv lub cub tawg uas cov hlau raug cua sov mus rau nws qhov chaw yaj. Thaum yaj, cov hlau kua raug nchuav rau hauv cov pwm kom tsim cov duab thiab qhov loj ntawm cov hlau log hnyav.

- Kev Ua Txhuas: Yog hais txog txhuas, cov hlau uas yaj lawm yuav raug nchuav rau hauv cov pwm uas tsim los tsim cov qauv hnyav tshwj xeeb. Tom qab txias lawm, cov hnyav yuav raug tshem tawm ntawm cov pwm.

- Kev Ua Zinc thiab Hlau Casting: Cov txheej txheem zoo sib xws yog siv rau zinc thiab hlau, txawm hais tias cov ntsiab lus yaj thiab cov txheej txheem yuav txawv me ntsis vim yog cov khoom sib txawv ntawm cov hlau no.

 

3. Kev Siv Tshuab thiab Kev Ua tiav

Tom qab ua tiav cov khoom siv hnyav ntawm lub log, feem ntau yuav tsum tau siv tshuab ntxiv kom ua tiav qhov loj me. Qhov no yuav suav nrog kev txiav, sib tsoo, lossis khawb kom ntseeg tau tias cov khoom siv hnyav haum rau ntawm lub log.

Cov txheej txheem ua tiav, xws li kev pleev xim lossis pleev xim, kuj tseem siv tau los txhim kho qhov zoo nkauj thiab tiv thaiv cov hnyav kom tsis txhob xeb. Piv txwv li, cov hnyav zinc yuav raug pleev xim nrog ib txheej zinc kom tiv thaiv xeb, thaum cov hnyav yas yuav raug pleev xim rau lub hom phiaj zoo nkauj.

 

4. Kev Tswj Xyuas Zoo

Kev tswj xyuas zoo yog ib qho tseem ceeb ntawm cov txheej txheem tsim khoom. Cov chaw tsim khoom siv cov txheej txheem kuaj xyuas kom ntseeg tau tias txhua lub log hnyav ua tau raws li cov qauv kev lag luam thiab cov lus qhia. Qhov no yuav suav nrog:

- Kev Ntsuas Qhov Hnyav: Txhua qhov hnyav raug ntsuas kom paub tseeb tias nws ua tau raws li cov qib kev kam rau siab tau teev tseg.

- Kev Tshuaj Xyuas Qhov Ntev: Kev ntsuas raug ntsuas kom paub tseeb tias qhov hnyav nyob hauv qhov ntev uas xav tau.

- Kev Ntsuas Kev Ruaj Khov: Cov qhov hnyav yuav raug rau kev sim kev ntxhov siab los ntsuas lawv cov kev ua tau zoo hauv ntau yam xwm txheej.

 

5. Kev Ntim Khoom thiab Kev Faib Khoom

Thaum cov qhov hnyav ntawm lub log tau dhau qhov kev tswj xyuas zoo lawm, lawv raug ntim rau kev faib tawm. Cov ntawv ntim khoom no yog tsim los tiv thaiv cov qhov hnyav thaum lub sijhawm thauj mus los thiab khaws cia. Cov chaw tsim khoom feem ntau muab cov ntawv lo qhia ntxaws ntxaws, suav nrog cov lus qhia txog qhov hnyav thiab cov lus qhia teeb tsa, los pab cov kws kho tsheb thiab cov neeg siv khoom.

Kauj ruam kawg yog xa cov qhov hnyav ntawm lub log mus rau cov khw muag khoom, cov khw muag tsheb, thiab cov chaw tsim khoom, qhov chaw uas lawv yuav siv rau hauv kev sib dhos lossis kev saib xyuas tsheb.
