Solvent-based laminationtxheej txheem, tseem hu ua cov ntawv cog lus qhuav lamination, suav nrog kev sib koom ua ke ntawm ob lossis ntau qhov kev tsim kho ntawm cov yeeb yaj kiab nrog PU nplaum uas muaj cov ntsiab lus hnyav thaum ua haujlwm. Cov ntsiab lus hnyav yog sib xyaw nrog cov nplaum ntawm qhov sib piv uas tso cai rau kev siv yooj yim ntawm cov nplaum rau zaj duab xis. Qhov sib tov ntawm cov nplaum thiab cov ntsiab lus hnyav yog kis los ntawm cov menyuam mandrel los ntawm kev sib hloov. Lub mandrel roller yog siv rau kev siv cov nplaum. Qhov no yog ib qho ntawm cov kev ua phem heev thiab kim heev vim tias yuav tsum muaj cua sov ntau hauv lub tshuab qhov cub kom evaporate cov ntsiab lus hnyav. Cov txheej txheem SB lamination yog qhov tsis xav tau vim nws tso tawm ntau cov pa phem rau hauv qhov chaw.
Solvent-free lamination, los yog SF lamination yog txheej txheem los ntawm ntau qhov kev teeb tsa yob tau siv los siv ob lub ntsiab lus PU nplaum ntawm ob qho tib si polymers thaum lub sij hawm lamination. Thaum lub sijhawm txheej txheem no, isocyanate-based PU pawg laminate yog ua tiav ntawm qhov ntsuas kub kom nce tus nqi ntawm cov tshuaj tiv thaiv.
Nyob rau hauv atmospheric tej yam kev mob, lub isocyanate yuav hnov mob nrog cov dej noo kom yield lub siab xav tau lub zog. Tom qab txheej txheej substrate nrog daim ntawv thov hnyav, ob daim ntawv sib koom ua ke yog nipped ntawm lub siab ntawm 2 ~ 4 bar los txhim kho adhesion thiab deg wettability. Cov txheej txheem yog yooj yim dua thaum piv rau lwm yam laminating tshuab vim qhov tsawg kawg nkaus lub zog yuav tsum tau thaum lub sij hawm tus txheej txheem. Lwm qhov zoo dua ntawm hom nplaum no yog nws lub peev xwm los txhim kho lub tshuab kom lub tsho ntawm kev kub ceev. Txawm hais tias lub lauj kaub lub neej ntawm SF lamination yog txwv, hom lamination no tseem suav tias yog ib puag ncig tus phooj ywg.Solventless laminationtseem suav tias yog ib puag ncig tus phooj ywg. Tsis muaj cua sov yuav tsum tau evaporate cov kuab tshuaj vim tias hom no tsis muaj hnyav.
