Kev ntsuas kub yog qhov tshwm sim tshaj plaws, txhua yam khoom lag luam lossis tshuab thev naus laus zis tuaj yeem tsis quav ntsej qhov tseem ceeb tshaj plaws no, piv txwv li, nyob rau hauv cov txheej txheem ntawm cov khoom siv ua acrylic, kub ua lub luag haujlwm tseem ceeb hauv kev rov siv dua. Piv txwv li, qhov kub thiab txias dua tau haum rau acrylic kub khoov? Yog li dab tsi yog qhov cuam tshuam ntawm kub ntawm acrylic?
Thaum peb hais txog cawv ntawm kub ntawm acrylic, peb yuav tsum hais txog tus ciam ntawm qhov ntsuas kub, nrog 85 ° C raws li ciam. Thaum ntsuas qhov ntsuas kub dhau qhov ntsuas kub no, nws yog rau kev ua acrylic. Thaum qhov ntsuas kub tau mus txog, acrylic pib deform thiab muag maj mam. Lub sijhawm no, nws yooj yim rau peb kom peb nqa txhua yam kev siv tshuab kub khoov rau ntawm acrylic los ua txhua yam ntawm cov khoom lag luam acrylic. Thiab qhov kub thiab txias tseem tuaj yeem txhim kho qhov yooj thiab lub zog ntawm plexiglass rau qee yam, ua ke nrog cuam tshuam lub zog.
Thaum qhov kub kub tsawg dua li 85 ℃, qhov kev hloov kho sab saum toj thiab muag muag yuav tsis tshwm sim. Tsis tas li ntawd tsis ntshai tshav ntuj, xws li siv sijhawm sab nraum zoov siv qee lub thawv teeb thiab lwm yam khoom. Kev kho xeb kuj tseem ceeb heev, kom ntseeg tau siv lub sijhawm ntev sab nraud.
Tswj qhov ntsuas kub, qhov kub sib txawv ntawm cov acrylic ua haujlwm yuav sib haum sib txawv, kev ua tau zoo kuj yuav hloov pauv. Nws kuj tseem muaj feem xyuam nrog tuab ntawm daim ntawv, uas yooj yim rau deform thaum daim ntawv tuab xav tau kub ntau dua. Qhov kub saum toj no tsuas yog ua rau kev ua cov thicker acrylic casting phaj.
