Ukusabela kwamakhemikhali okuyisisekelo ngesikhathi se-solventless lamination

Ngokuthuthuka okuqhubekayo kobuchwepheshe, i-solventless lamination yamukelwa iningi labakhiqizi bephakheji abaguquguqukayo.

Ngokushesha, kulula, kunobungani bemvelo, okungabizi kakhulu kuyizinzuzo ze-lamination engena-solvent.

Kubaluleke kakhulu kithi ukuthi sazi ukusabela kwamakhemikhali okuyisisekelo ngesikhathi se-solventless lamination ukuze sikhiqize ubuningi obungcono.

Ingxenye ezimbiliI-adhesive engena-solventlessyenziwe nge-polyurethane (PU), i-PU yahlanganiswa yi-isocyanate(-NCO) ebizwa kakhulu ngokuthi i-A component, kanye ne-polyol(-OH) ebizwa kakhulu ngokuthi yi-B component.Imininingwane yokusabela sicela uhlole ngezansi;

Ukusabela okuyinhloko kuphakathi kuka-A no-B, i-NCO ine-chemical react with -OH, ngesikhathi esifanayo, ngenxa yamanzi futhi ineqembu elisebenzayo -OH, amanzi azoba nokusabela kwamakhemikhali ngokukhishwa kwengxenye ye-CO.₂,I-Carbon dioxide.Futhi i-polyurea.

Inkampani CO₂ ingase ibangele inkinga yebhamuza futhi i-polyurea ingase ibangele uphawu lokulwa nokushisa.Ngaphandle kwalokho uma umswakama uphakeme ngokwanele, amanzi azodla ingxenye engu-A eningi kakhulu.Umphumela uba ukuthi okunamathelayo akukwazi ukwelapha ngo-100% futhi amandla okubopha azokwehla.

Kafushane, siphakamisa ukuthi;

Ukugcinwa kokunamathela kufanele Kugcinwe endaweni epholile, eyomile kude nomswakama

Indawo yokusebenzela kufanele igcine umswakama uphakathi kuka-30%~70%, futhi isebenzise i-AC ukulawula inani lomswakamo.

Ngenhla ukusabela kwamakhemikhali okuyisisekelo phakathi kokunamathelayo kwengxenye eyodwa, kodwa okunamathelayo kwengxenye eyodwa kuzohluka ngokuphelele, sizokwethula ukusabela kwamakhemikhali kwengxenye eyodwa esikhathini esizayo.
