Lub hom phiaj tseem ceeb:
1. Sim seb qhov tshuaj tiv thaiv thawj zaug ntawm cov nplaum yog qhov ib txwm muaj.
2. Sim seb qhov kev ua tau zoo ntawm cov yeeb yaj kiab puas yog qhov qub.
Txoj Kev:
Txiav ib daim zaj duab xis laminated tom qab tsim khoom thiab muab tso rau hauv qhov cub nrog qhov kub siab kom saib xyuas qhov kev ua tau zoo ntawm lamination thawj zaug.
Feem ntau, qhov kub thiab txias yog 80 ℃ rau 30 feeb.
Cov ntsiab lus ua haujlwm:
1. Txiav cov yeeb yaj kiab li 20cm * 20cm, uas tuaj yeem pw hauv qhov cub kom tiaj tus.
2. Txhua yam qauv luam tawm yuav tsum muaj (meej, luam tawm lossis qee qhov chaw xav tau kev ceev faj)
3. Cov qauv yuav tsum yog thawj yob thiab yob kawg ntawm txhua hnub ua haujlwm. Npog tag nrho cov yob yuav zoo tshaj plaws.
Cov Lus Cim:
1. Qhov kev sim no yog rau kev pib ua haujlwm ntawm lamination; lub zog lo tsis sib npaug rau qhov tshwm sim kho zaum kawg.
2. Nws yog qhov lees txais los saib cov laminates qhuav los ntawm qhov kev sim no. Txawm li cas los xij, cov laminates uas tsis muaj kuab tshuaj ua tsis tau. Cov txheej nplaum yuav ntsws thaum txiav tawm, vim yog cov yam ntxwv ntawm cov nplaum uas tsis muaj kuab tshuaj. Lub sijhawm no, cov tsos ntawm cov laminates yuav tsum tsis zoo, tab sis nws tsis cuam tshuam nrog cov khoom kho zaum kawg.
3. Kev sim kho sai tsis tuaj yeem siv rau kev hloov pauv hlau.
