4. Kev cuam tshuam ib puag ncig
Txawm hais tias dej pab txhaj tshuaj molding muaj qee qhov txo qis ntawm cov khoom pov tseg yas, nws tau qhia txog qhov teeb meem ntawm ib puag ncig tshiab. Nyob rau hauv cov txheej txheem ntawm cov dej pab kev txhaj tshuaj molding, qhov txhaj tshuaj molded qhov chaw yuav tsum tau siv ntau cov dej kom txias thiab sib cais thaum lub sij hawm tus txheej txheem ntawm adapting rau dej, uas tej zaum yuav ua rau lub tsim ntawm cov dej khib nyiab. Lub caij no, qee qhov tshwj xeeb dej-soluble additives yuav ua rau muaj kev phom sij rau ib puag ncig. Yog li ntawd, thaum txhawb kev thov cov dej pab txhaj tshuaj molding tshuab, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog nws cov kev cuam tshuam rau ib puag ncig thiab nrhiav kev daws teeb meem.
5. Kev ruaj ntseg thiab kev ntseeg tau
Vim yog qhov tshiab ntawm cov dej pab kev txhaj tshuaj molding tshuab, nws cov kev ruaj ntseg thiab kev ntseeg siab yuav tsis raug txheeb xyuas tag nrho. Thaum lub sij hawm txhaj tshuaj molding txheej txheem, kev tshawb fawb thiab kev xyaum ntxiv yog xav tau los xyuas kom meej qhov kev sib cais ntawm kev txhaj tshuaj molded qhov chaw thiab dej, qhov ua kom txias, thiab tsim cov kav dej. Qhov no yuav ua rau muaj kev hloov pauv zoo lossis kev nyuaj hauv kev tsim khoom tiag tiag, xav tau kev txhim kho txuas ntxiv thiab kev ua kom zoo dua qub.
Zuag qhia tag nrho, txawm hais tias dej pab txhaj tshuaj molding tshuab muaj peev xwm nyob rau hauv qee yam, nws kuj muaj qee qhov teeb meem pom tseeb thiab teeb meem. Hauv kev teb rau cov teeb meem no, peb yuav tsum tau ua qhov kev tshawb fawb tob tob thiab kev tsim kho tshiab, maj mam kov yeej cov teeb meem no los ntawm kev siv thev naus laus zis thiab kev ua kom zoo tshaj plaws, txhawm rau ua kom muaj kev txhim kho ruaj khov ntawm cov dej pab txhaj tshuaj molding tshuab.
