Hauv -mould labeling (IML) yog lub tshuab kho kom zoo nkauj yas uas siv qhov kub, siab, thiab lub sijhawm xav tau thaum lub sijhawm molding (xws li txhaj tshuaj molding thiab tshuab moulding) ib txhij muab cov txheej txheem zoo nkauj rau hauv pwm. Nws feem ntau yog siv rau tshuab tshuab- molded thiab txhaj tshuaj- cov khoom molded ua los ntawm cov ntaub ntawv xws li PP, PE, thiab PET. Lub hauv paus ntsiab lus tseem ceeb yog ua ntej tshuab moulding lossis txhaj tshuaj molding, ib daim ntawv ua ntej - muab tso rau hauv pwm kab noj hniav. Tom qab cov pwm kaw lawm, qhov kub thiab siab siab nyob rau hauv cov pwm yaj cov nplaum tshwj xeeb nyob rau sab nraum qab ntawm daim ntawv lo, fuse nws mus rau saum npoo ntawm lub raj mis yas los yog txhaj tshuaj - molded ib feem, tsim cov khoom zoo nkauj luam tawm hauv ib kauj ruam.
Hauv -mould labeling (IML) yog ib ceg tseem ceeb ntawm -pwm kho kom zoo nkauj (IMD) thev naus laus zis, feem ntau muab faib ua kev txhaj tshuaj molding IML thiab tshuab moulding IML. Tshuab moulding IML tau siv ua ntej thiab dav dua, thaum txhaj tshuaj molding IML tau pom kev txhim kho sai dua nyob rau xyoo tas los no vim muaj peev txheej ntau dua. Tam sim no, muaj ob txoj hauv kev tseem ceeb rau hauv - pwm daim ntawv lo adsorption: ib qho yog lub tshuab nqus tsev tsis zoo siab adsorption, uas siv lub tshuab nqus tsev micropores hauv pwm los adsorb daim ntawv lo rau hauv pwm kab noj hniav; cov thev naus laus zis no paub tab, siv dav, thiab tus nqi qis dua -. Lwm qhov yog electrostatic adsorption. Hauv - cov ntaub ntawv sau npe pwm feem ntau muaj peb txheej: txheej luam ntawv uas tau txais tus cwj mem los ua cov duab xim, ib txheej nruab nrab uas muab cov tawv tawv thiab ruaj khov kom ntseeg tau tias kev sau npe raug, thiab cov nplaum nplaum uas melts ntawm qhov kub thiab txias kom ruaj khov daim ntawv lo rau lub thawv.
