Filimi yo gupakira ibiryo Umuzingo wo gupakira imashini ipakira ikoresheje pulasitiki

Filimi ivanze yakozwe mu byiciro bibiri cyangwa byinshi igomba kuba itandukanywa nk'ifilimi imwe. Ibi bikubiyemo ibirenze gusa kole iri hagati ya filimi ebyiri. Bifitanye isano kandi na filimi ya wino. Kole ni ibikoresho bya sintetike Kole nyinshi ni kole ya polyurethane (PU) ifite ibice bibiri. Uburyo bwo gucukura buvura kole. Kole iri ku buso bw'ubutaka ahanini ni inzira ifatika kandi igice gito gusa ni inzira ya shimi. Muri iki gihe, ibice bya kole bicukurwa hamwe n'ibice biri muri filimi ya pulasitiki hanyuma bigakira.
Iyo firime ivanze yamaze gucapwa mu gihe cyo guhuza, kole na wino bigomba kuzuza ibisabwa byinshi. Icy'ingenzi cyane ni uko urwego rw'imbere rugomba kugira ubushobozi bwo gufata neza no kuma mbere yo gufunga. Ibi bivuze ko nta bisigazwa by'umushongi byemewe mu gikoresho cyacapwe. Ariko umushongi cyangwa alcool bikunze gusigara mu gikoresho cya wino. Kubera iyo mpamvu, imiterere y'umushongi igomba kuba ishobora gufatana na radicals yigenga (amatsinda ya -OH). Bitabaye ibyo, kole n'umuti uvura bizahita byikora ubwabyo kandi bigatakaza imiterere yabyo y'umwimerere.
Muri kole, kole zishingiye ku binyabutabire zitandukanye n'izidafite ibinyabutabire nka kole za UV. Imvange y'imashini zikoresha ibinyabutabire isaba umuyoboro wo kumisha kugira ngo ikinyabutabire gihinduke. Iyo hakoreshejwe kole za UV, urumuri rwa UV runyura muri filime ivanze rugana kuri kole kugira ngo kole ihinduke hamwe.
1. Imvange yumye
Bivuga uburyo kole ivangavanga iyo yumye. Ubwa mbere, kole ishyirwa ku kintu cy'ingenzi. Nyuma yo kuma mu mwobo wo kumisha, ibintu byose bishongesha biri muri kole birumishwa. Uburyo bwo gushongesha kole, gufatanya ikindi kintu kuri yo, gukonjesha, no kuyitunganya kugira ngo haboneke ikintu cy'ingenzi gifite imiterere myiza.
2. Imvange yo gusohora
Bizwi kandi nka casting compounding, ikaba ari imwe mu nzira z'ingenzi zo gukora compound flexible packing. Ishongesha thermoplastics nka polyethylene na polypropylene mu mashini ikora extrusion compounding, igasohoka neza mu gapfunyika gato kavuye ku mutwe ugororotse, kandi ikomeza gupfukwa ku gikoresho cyo hasi, agapfundikizo k'ibice bibiri cyangwa byinshi gakorwa hakoreshejwe pressure roller hanyuma ikonjesha hakoreshejwe cooler roller.
Gutunganya imvange bifite ibyiza byo kwihuta mu gukora, gukora byoroshye, gukora ahantu hasukuye, gukora neza cyane, gukora byoroshye, ku giciro gito, nta bisigazwa by'ibinyabutabire.
