Cov tshuaj lom neeg yooj yim thaum lub sijhawm lamination tsis muaj kuab tshuaj

Nrog rau kev nce qib ntawm thev naus laus zis, feem ntau ntawm cov chaw tsim khoom siv tau yooj yim txais tos cov lamination tsis muaj kuab tshuaj.

Cov txiaj ntsig ntawm kev lamination tsis muaj kuab tshuaj yog qhov ua tau sai dua, yooj yim dua, zoo dua rau ib puag ncig, thiab pheej yig dua.

Nws yog ib qho tseem ceeb heev rau peb kom paub txog cov tshuaj lom neeg yooj yim thaum lub sijhawm lamination tsis muaj kuab tshuaj rau kev tsim khoom ntau dua.

Ob qho khoomCov nplaum tsis muaj kuab tshuajyog ua los ntawm polyurethane (PU), PU tau ua ke los ntawm isocyanate (-NCO) feem ntau hu ua A Cheebtsam, thiab polyol (-OH) feem ntau hu ua B Cheebtsam. Cov ntsiab lus ntawm kev ua tshuaj tiv thaiv thov kos rau hauv qab no;

Qhov tshuaj tiv thaiv thawj zaug yog nyob nruab nrab ntawm A thiab B, -NCO muaj tshuaj lom neeg ua rau -OH, tib lub sijhawm, vim dej kuj muaj pawg ua haujlwm -OH, dej yuav muaj tshuaj lom neeg ua rau A tivthaiv tso tawm CO₂, Cov pa roj carbon dioxide. Thiab polyurea.

Tus CO₂ tej zaum yuav ua rau muaj teeb meem npuas thiab polyurea tej zaum yuav ua rau lub foob tiv thaiv cua sov. Dhau li ntawm qhov ntawd yog tias cov av noo siab txaus, cov dej yuav siv ntau yam A. Qhov tshwm sim yog tias cov nplaum tsis tuaj yeem kho tau 100% thiab lub zog sib txuas yuav qis dua.

Hauv kev xaus lus, peb xav tias;

Qhov khaws cia ntawm cov nplaum yuav tsum tau khaws cia rau hauv qhov chaw txias, qhuav kom deb ntawm cov dej noo

Lub rooj cob qhia yuav tsum khaws cov av noo ntawm 30% ~ 70%, thiab siv AC los tswj cov av noo.

Saum toj no yog cov tshuaj lom neeg yooj yim ntawm ob lub nplaum, tab sis cov nplaum mono-component yuav txawv kiag li, peb yuav qhia txog cov tshuaj lom neeg mono component yav tom ntej.
