Guhindura ibicu ni iki?Ni irihe hame ryo guhumeka?

Ukurikije uburyo bwo gukora gereza, uburyo bwo guhanagura burashobora kugabanywa muburyo bwo gukuramo ibicuruzwa no gutera inshinge.Ibishya byateye imbere birimo ibice byinshi byo guhanagura no kurambura.Paruwasi ya pulasitike ya tubular yabonetse mugusohora cyangwa guterwa inshinge za termoplastique zishyirwa mubice bigabanijwemo mugihe bishyushye (cyangwa bishyushye kugirango byoroshe), kandi umwuka wugarijwe winjizwa muri gereza ako kanya akimara gufungwa kugirango uhuhishe parison ya plastike .Iraguka kandi igafatana hafi kurukuta rwimbere rwububiko, hanyuma nyuma yo gukonjesha no kumeneka, haboneka ibicuruzwa bitandukanye.Uburyo bwo gukora firime ya firime irasa cyane muburyo bwo guhanagura ibicuruzwa bidafite akamaro, ariko ntibikoresha ifu.Urebye uburyo bwa tekinoroji yo gutunganya plastike itondekanya, uburyo bwo kubumba firime ya firime isanzwe ishyirwa mubikorwa.Igikorwa cyo kubumba cyakoreshejwe mu ikubitiro mu gukora intungamubiri nke za polyethylene mu gihe cy'Intambara ya Kabiri y'Isi Yose.Mu mpera z'imyaka ya za 1950, hamwe no kuvuka kwa polyethylene yuzuye kandi hanatezwa imbere imashini zikora imashini, ikoreshwa rya tekinoroji.Ingano yububiko butagaragara irashobora kugera kuri litiro ibihumbi, kandi umusaruro umwe wagenzuye mudasobwa.Plastike ikwiranye no guhumeka harimo polyethylene, chloride ya polyvinyl, polypropilene, polyester, nibindi, kandi ibikoresho byabonetse bikoreshwa cyane nkibikoresho byo gupakira inganda.
