Inkinobho Yekhishini Yokudonsa Inkinobho: Izindawo Ezibalulekile Zokusebenzisa Kufakazela Iziphumano Zokuthenga
Umthombo wokuthengisa kuyindawo ebalulekile yokusebenzisa inkinobho yekhishini yokudonsa inkinobho, ekhathaza ukuthi kudingeka ngokubanzi inkinobho elihlakaniphile, elinamandla. Lezi zinkinobho zihlawulisa izithixo ezihlanzekileyo njenge-PE, PP, ne-PVC ukuze zenze inkinobho encane, enjalo—njengezibhodlela zezithelo, izibhodlela zezithelo ezintsha, nezibhodlela zokugaya okuphatswa emkhahweni—ezivikela izinto, zilungise umvumo, futhi zilungise ububi bokuthunyelwa. Amamodeli amasha angasebenzisa futhi izithixo ezivuselekile noma ezingalunganga (njenge-PLA), okuhambisana nemigomo yamanjebala ngokuthembeka, kodwa kuyadingeka kumapakethi amancane amadala noma amakhulu amakhulu.
Ukwalimba kusiza kakhulu ezilwini zokudonsa iziphiwo ukuthutha izimpahla zakwalimba futhi ukulungiselela imisebenzi yekwalimba. Le zixhobo zakhiwa iziphiwo ezikhethekileyo zokwalimba: iziphiwo zomlamo (ukumthintela izithethe, ukugcina ubushani balesilimela, nokulungiselela ubomi), iziphiwo zesigubhu (ukudizayiza izibonelo futhi ukuvikela izimpahla kumzimba omuhle), neziphiwo zesisaleni (ukugcina izindlu zempilo). Kuningi le zixhobo manje zihlelekile kumagugu amathiphu okuyi-UV noma ayihlakeleyo, ekuxhasa izinhloso zokwalimba ezenziwayo ngendlela ethembekileyo kanye nokuncipha kwesandla seplastic emakhanda—lokhu kubaluleke kakhulu kubantu abakwalima kuAsia, u-Erophe, ne-Amrika eyongedla.
Imigangeli yezimali eziphathelene kakhulu ihlukanisa isilinganiso sesiseko samaphakheji amadala, ukusebenzisa ubumnandi nokulondoloza kwamagugu. Kwi-industri yesiphilungu, ikhwele imifilo ethulwane kanye ngezintshukumo ezincane kwezempilo kwezithuthi zemithi yezempilo nezibhambo zezixhumanisi zezempilo, ukuxhasana nezivumelwano eziphambili ze-FDA ne-CE. Isektor yezinhlelo zeshumi usebenzisa imifilo yayo engavaleki umshimba ukuvikela iziqhamo ezihlukumezi (isb., izibhambo zomlando) ngexesha lokugcina kanye nokuthunyelwa. Ngaphezu koko, indalo yokudla iyisebenzisa imifilo yayo engavaleki ukuvikela iglasi, iingcinga ze-metal, kunye nezinye iziziba—uyakhaqha ubumfumba bomkhiqizo ngexesha lokufakelwa. Le miqhalo ethile ibonisa ubunzima bekhonkco ngaphandle kwezandla eziphucwayo.
