Ua ntej tsim cov kuab tshuaj tsis muaj tshuaj, nws yuav tsum ua tib zoo nyeem cov txheej txheem tsim cov ntaub ntawv thiab cov kev xav tau thiab kev ceev faj rau qhov sib piv ntawm cov kuab tshuaj tsis muaj nplaum, kev siv kub, av noo, kev kho mob, thiab cov txheej txheem tsis.Ua ntej tsim khoom, nws yog ib qho tsim nyog los xyuas kom meej tias cov khoom siv nplaum siv tsis muaj qhov txawv txav.Thaum pom muaj qhov txawv txav uas cuam tshuam rau viscosity, lawv yuav tsum tau nres tam sim ntawd thiab sib tham nrog lub tuam txhab cov neeg ua haujlwm.Ua ntej siv lub tshuab laminating tsis muaj kuab tshuaj, nws yog ib qho tsim nyog yuav tsum preheat qhov sib tov, gluing system, thiab laminating system ua ntej.Ua ntej kev tsim cov kuab tshuaj tsis muaj tshuaj, nws yog ib qho tsim nyog yuav tsum xyuas kom meej tias qhov chaw ntawm cov roj hmab rollers, rigid rolls, thiab lwm yam.Cheebtsam ntawm cov khoom siv ntawm lub tshuab ua kom tsis muaj kuab lom yog huv si.
Ua ntej pib, nws yog ib qho tsim nyog yuav tsum paub meej dua seb qhov zoo ntawm cov khoom sib xyaw ua tau raws li qhov yuav tsum tau ua ntawm cov khoom sib xyaw.Qhov nro ntawm cov yeeb yaj kiab feem ntau yuav tsum siab dua 40 dynes, thiab qhov nro ntawm BOPA thiab PET zaj duab xis yuav tsum siab dua 50 dynes.Ua ntej kev tsim khoom loj, kev ntseeg siab ntawm zaj duab xis yuav tsum tau sim los ntawm kev sim kom tsis txhob muaj kev pheej hmoo.Xyuas seb puas muaj kev puas tsuaj lossis qhov txawv txav hauv cov nplaum.Yog tias pom muaj qhov txawv txav, muab pov tseg cov nplaum thiab ntxuav lub tshuab sib tov.Tom qab paub meej tias tsis muaj qhov txawv txav hauv cov nplaum, siv lub khob pov tseg los xyuas seb qhov sib xyaw tshuab sib xyaw puas yog.Kev tsim khoom tuaj yeem ua tiav tom qab qhov sib txawv ntawm qhov sib txawv yog li ntawm 1%.
Thaum lub sij hawm tsim khoom, nws yog ib qho tsim nyog kom paub meej tias cov khoom zoo.Tom qab kev sib xyaw ua ke ntawm 100-150m, lub tshuab yuav tsum raug tso tseg kom paub meej tias seb qhov sib xyaw zoo li cas, txheej txheej, nro, thiab lwm yam ntawm cov khoom ua tau raws li qhov xav tau.Thaum lub sij hawm tsim cov txheej txheem, tag nrho cov txheej txheem tsis, suav nrog ib puag ncig kub, av noo, sib xyaw substrate, thiab cov txheej txheem cov khoom siv, yuav tsum tau sau tseg kom pab txhawb kev taug qab thiab txheeb xyuas cov teeb meem zoo.
Cov txheej txheem tsis xws li kev siv thiab khaws cia ib puag ncig ntawm cov nplaum, kev siv kub, lub sijhawm ua haujlwm, thiab qhov sib piv ntawm cov kua nplaum tsis muaj nplaum yuav tsum xa mus rau cov khoom siv kev qhia.Cov av noo nyob rau hauv qhov chaw ua haujlwm yuav tsum tswj ntawm 40% -70%.Thaum cov av noo yog ≥ 70%, sib txuas lus nrog lub tuam txhab cov neeg ua haujlwm thiab tsim nyog nce cov isocyanate tivthaiv (KangDa Cov Khoom Tshiab A tivthaiv), thiab paub meej tias nws los ntawm kev ntsuas me me ua ntej siv cov khoom siv.Thaum cov av noo ib puag ncig yog ≤ 30%, sib txuas lus nrog lub tuam txhab cov neeg ua haujlwm thiab tsim nyog nce hydroxyl tivthaiv (B tivthaiv), thiab paub meej tias nws los ntawm kev sim ua ntej siv batch.Cov khoom yuav tsum tau ua tib zoo saib xyuas thaum lub sijhawm thauj mus los thiab thauj khoom thiab thauj khoom, kom tsis txhob muaj kev sib tsoo, kev sib tsoo, thiab lub zog hnyav, thiab tiv thaiv cua thiab tshav ntuj.Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua, thiab qhuav, thiab khaws cia rau lub sijhawm cia ntawm 6 lub hlis.Tom qab kev ua haujlwm sib xyaw ua tiav, qhov kub ntawm qhov kub yog 35 ° C-50 ° C, thiab lub sijhawm kho tau hloov kho raws li qhov sib txawv ntawm cov substrates.Lub curing humidity feem ntau tswj ntawm 40% -70%.
