Nrog rau kev nce qib ntawm cov thev naus laus zis tas mus li, cov kuab tshuaj tsis muaj kuab lom tau txais tos los ntawm feem ntau ntawm cov chaw tsim khoom lag luam.
Faster, yooj yim dua, ntau tus phooj ywg ib puag ncig, kev siv nyiaj ntau dua yog qhov zoo ntawm cov lamination tsis muaj kuab lom.
Nws yog ib qho tseem ceeb heev rau peb kom paub cov tshuaj lom neeg cov tshuaj tiv thaiv thaum lub sij hawm solventless lamination kom zoo dua huab hwm coj ntau lawm.
Ob yamSolventless nplaumyog tsim los ntawm polyurethane (PU), PU tau ua ke los ntawm isocyanate (-NCO) feem ntau hu ua A tivthaiv, thiab polyol (-OH) feem ntau hu ua B tivthaiv.Cov ntsiab lus ntawm cov tshuaj tiv thaiv thov xyuas hauv qab no;
Cov tshuaj tiv thaiv tseem ceeb yog nruab nrab ntawm A thiab B, -NCO muaj tshuaj lom neeg nrog -OH, tib lub sijhawm, vim dej kuj muaj -OH ua haujlwm pab pawg, dej yuav muaj tshuaj tiv thaiv nrog A tivthaiv tso tawm CO2, Cov pa roj carbon dioxide.Thiab polyurea.
The CO2 tej zaum yuav ua rau muaj teeb meem npuas thiab polyurea tuaj yeem ua rau lub foob tiv thaiv tshav kub.Dhau li yog tias cov av noo txaus, cov dej yuav haus ntau dhau A tivthaiv.Qhov tshwm sim yog tias cov nplaum tsis tuaj yeem kho tau 100% thiab lub zog sib txuas yuav qis dua.
Hauv cov ntsiab lus, peb xav tias;
Kev khaws cov nplaum yuav tsum khaws cia rau hauv qhov chaw txias, qhuav kom deb ntawm noo 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 tiv thaiv yooj yim ntawm ob qho khoom nplaum, tab sis mono-tham nplaum nplaum yuav txawv kiag li, peb yuav qhia cov tshuaj tiv thaiv mono tiv thaiv yav tom ntej.
