Yuav ua li cas cov khoom siv ua npuas dej tsim tau
Cov khoom lag luam ua npuasy yog tsim cov txheej txheem hu ua npuas molding. Ua npuas ncauj moulding cuam tshuam nrog kev tsim cov khoom siv ua npuas ncauj, muab hliv rau hauv cov pwm, thiab tso cai rau nws nthuav dav thiab muaj zog rau qhov xav tau. Ntawm no yog cov lus qhia luv luv txog cov khoom ua npuas dej yog tsim khoom:
1. Khoom npaj: thawj kauj ruam hauv kev tsim cov khoom lag luam ua npuas ncauj tab tom npaj cov khoom siv ua npuas ncauj. Qhov no feem ntau yuav cuam tshuam cov tshuaj ua ke los tsim cov khoom siv ua npuas dej nthuav dav uas tuaj yeem ua pwm thiab ntau thiab tsawg.
2. Pwm npaj: ib zaug cov khoom siv ua npuas ncauj yog npaj tau, nws yog nchuav rau hauv cov pwm uas yog qhov xav tau ntawm cov khoom tiav. Cov pwm feem ntau yog ua los ntawm cov khoom siv ceev xws li cov hlau lossis yas thiab tsim kom tau cov khoom siv ua npuas ncauj.
3. Ncuav thiab nthuav dav: cov ntaub ntawv ua npuas ncauj yog tom qab ntawd nchuav rau hauv pwm thiab tso cai nthuav dav. Raws li cov ntaub ntawv ua npuas ncauj nthuav tawm, nws puv cov pwm thiab siv rau ntawm cov pwm ntawm cov pwm. Cov txheej txheem nthuav dav feem ntau yuav siv sijhawm li ob peb feeb kom tiav.
4. Solidification: Tom qab cov khoom siv ua npuas ncauj tau nthuav mus sau cov pwm, nws tau tso cai rau cov khoom siv thiab tawv tawv. Qhov no tuaj yeem siv nyob txhua qhov chaw ntawm ob peb feeb txog rau ob peb teev, nyob ntawm seb hom khoom siv ua npuas ncauj siv.
5. Tshem tawm los ntawm pwm: Thaum cov khoom siv ua npuas ncauj tau muaj kev ruaj khov, cov khoom tiav tau raug tshem tawm ntawm cov pwm. Cov khoom ua npuas ncauj yog tom qab ntawd txiav thiab ua tiav los xyuas kom nws ua tau raws li cov lus qhia tshwj xeeb.
Zuag qhia tag nrho, ua npuas dej yog tsim tau siv cov txheej txheem yooj yim thiab ua kom muaj ntau cov khoom siv ua npuas dej. Txawm hais tias nws yog ua npuas ncauj, lub ncoo, rwb thaiv tsev, lossis txawm tias muaj rooj tog, ua npuas ncauj khoom ua cov khoom lag luam tseem ceeb hauv ntau qhov kev lag luam thiab muaj txiaj ntsig zoo thiab raug nqi siv khoom siv.
Tom qab nyeem abou cov no seb puas paub ntau ntxiv txog yuav ua li cas cov khoom siv ua npuas dej, thiab peb lub tshuab yuav coj koj mus rau lub ntiaj teb kom paub txog ua npuas dej ib yam nkaus.
