Gukubita ibiceri ni inzira ikoreshwa cyane mu gukora ibicuruzwa bya pulasitike, cyane cyane ibikoresho bidafite umumaro, ibice by'imodoka, n'ibikoresho byo mu nganda. Nyuma yimyaka myinshi yo kwitoza, navuze muri make ibintu byinshi byingenzi bishobora kuba nkibimenyerewe kubimenyereza.
Icya mbere, guhitamo ibikoresho ni ngombwa. Polyethylene (PE), polypropilene (PP), na tereethalate polyethylene (PET) ni ibikoresho bisanzwe bibumba. Kugenda kwabo, gushonga, hamwe no kurwanya imiti bigira ingaruka nziza muburyo bwiza. Kurugero, hejuru - ubucucike bwa polyethylene (HDPE) burakwiriye kubintu bikomye, mugihe hasi - ubucucike bwa polyethylene (LDPE) burakwiriye kubicuruzwa byoroshye. Byongeye kandi, kumisha ibikoresho fatizo ni ngombwa. Ubushuhe busigaye bushobora gutera ibibyimba cyangwa ubusembwa, bityo pre - gukama mubisanzwe bikorwa kuri dogere 80-100 kumasaha 2-4.
Igishushanyo mbonera hamwe nibikorwa byo gutezimbere nabyo ni ibintu byingenzi. Gukubita ibishushanyo bigomba kwemeza gukonja kugirango wirinde ibimenyetso cyangwa guhinduka. Mubisanzwe, ubushyuhe bwububiko bugenzurwa hagati ya dogere 20 - 60, hamwe nagaciro kihariye bitewe nubwoko bwibintu. Umuvuduko ukabije nigihe birakomeye. Umuvuduko ukabije urashobora gutuma uburebure bwurukuta butaringaniye, mugihe umuvuduko mwinshi urashobora gutuma gereza icika. Imyitozo yerekana ko umuvuduko uhuha kubice bitagaragara muri rusange ukomeza hagati ya 0.3 na 1.0 MPa, naho igipimo cyo guturika (ikigereranyo cya diameter igice cya diameter na parison) ni byiza hagati ya 2 na 4.
Byongeye kandi, ibibazo rusange byumusaruro bisaba ibisubizo bigamije. Kurugero, kugabanuka kwa parison birashobora kunozwa mukongera umuvuduko wo gusohora cyangwa kugabanya ubushyuhe bwashonga; gutandukana kwurukuta bisaba guhindura icyuho cyo gupfa cyangwa guhitamo igihe cyo gukubita. Kohereza intambwe - intambwe yo gutunganya, nko gutema, gusukura, no kuvura hejuru (nko gutera cyangwa amashanyarazi), nabyo bigira ingaruka kumasoko yibicuruzwa byanyuma.
Muri make, ubuziranenge bwibihuru - ibice byabumbwe biterwa no kugenzura byimazeyo ibikoresho, ibikoresho, inzira, nuburambe. Gukomeza kunoza ibipimo byumusaruro no gufata neza ibikoresho birashobora kunoza imikorere no kugabanya ibiciro, bitanga ibisubizo birushanwe muruganda.
