Raws li peb txhua tus paub, yog tias peb xav kom peb cov cuab yeej ua haujlwm ib txwm siv sijhawm ntev, peb yuav tsum tswj nws. Nyob rau hauv txoj kev no, nws tuaj yeem tsis tsuas yog txo qhov tsis ua haujlwm ntawm cov khoom siv, tab sis kuj tseem txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv. Tam sim no cia peb saib yuav ua li cas tswj peb lub tshuab moulding tshuab.
Kev tu cov txheej txheem ntawm cov duab molding tshuab
1. Tshawb xyuas ua ntej thiab tom qab siv
1) Peb yuav tsum xyuas ua ntej thiab tom qab siv lub tshuab ua npuas ncauj. Peb yuav tsum xyuas kom meej tias cov cuab yeej siv tau zoo li cas thiab seb puas muaj qhov txawv txav.
2) Tshwj xeeb, qhov taw qhia teeb yuav tsum tau txiav txim siab ua ntej. Yog tias muaj qee qhov yuam kev, cov teeb pom kev sib raug zoo tseem yuav teeb ncaj qha, yog li peb tsis tuaj yeem ua haujlwm ib txwm. Peb yuav tsum kuaj xyuas ua ntej, thiab xyuas kom meej tias qhov kev ua txhaum raug daws ua ntej siv.
3) Tom qab siv, tso tseg cov khoom siv, tua cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab tsis txhob siv txuas ntxiv, siv hluav taws xob, thiab lwm yam kom tsis txhob muaj teeb meem tsis tsim nyog.
2. Ua haujlwm tu yooj yim tsis tu ncua
Qhov tseeb, kev saib xyuas ntawm lub tshuab moulding tshuab tsis yooj yim heev, thiab cov neeg ua haujlwm uas feem ntau siv nws kuj paub yuav ua li cas nrog nws. Rau feem ntau cov lag luam, txhua tus neeg yuav tsum ua tib zoo ua haujlwm thiab xyuas nws tsis tu ncua hauv kev sib hloov, kom peb paub tias muaj teeb meem dab tsi tshwm sim thiab seb qee qhov yuav tsum tau hloov. Tsuav qhov kev saib xyuas yooj yim, nws kuj tuaj yeem zam ntau yam teeb meem. Kev siv lub neej ntev ntawm cov khoom siv tuaj yeem ua kom peb cov cai thiab kev txaus siab.
