Raws li lub sijhawm dhau mus, lub caij nplooj zeeg tseem nrawm, thiab tam sim no nws tau pib nkag rau lub caij ntuj no. Muaj qhov sib txawv loj ntawm qhov kub ntawm lub teb chaws. Sab qaum teb tuaj yeem ncav cuag qhov kub qis ntawm -30 degrees, thiab sab qab teb kub tshaj yog ntau tshaj 30 degrees, yog li kev xaiv ntawmkub yaj kua nplaumyog tshwj xeeb heev rau lub sijhawm no. Rau kev ua lag luam sab qaum teb, nws xav tau cov kua nplaum kub yaj uas tsis muaj qhov kub thiab txias, thiab rau cov lag luam sab qab teb, nws xav tau cov kua nplaum rau lub caij ntuj no nrog cov cua sov zoo dua. Qhov kev thov rau cov kua nplaum sib txawv hauv ntau thaj tsam.
Rau qhov project Velac, peb lub tuam txhab ua cov kev faib tawm kom raug. Rau cov ntawv thov kub uas tsis tshua muaj kub laminating cov khoom, thiab tib lub sij hawm txaus siab rau qhov txias txias, lub laminating kub thiab kam rau ua kub yuav raug qhia thaum shipping, muab cov neeg siv khoom kom meej meej.
Yuav ua li cas xaiv cov kua nplaum uas tsis kub? Ib qho yog kom nkag siab cov neeg siv khoom qhov kub thiab txias xav tau raws li cov neeg siv khoom hluav taws xob hauv cheeb tsam, thiab qhov thib ob yog kom nkag siab cov neeg siv khoom cov ntaub ntawv thiab ua kom raug cov ntaub ntawv sib txawv. Qhov thib peb yog kom nkag siab qhov xwm txheej ntawm tus neeg siv khoom cov khoom lag luam, yog nws siv tam sim lossis siv mus ntev; Nkag siab txog cov kev xav tau tiag tiag ntawm cov neeg siv khoom thiab ua kom raug zoo tuaj yeem txo cov neeg siv khoom tsis txaus siab.
