Itaranya hagati ya PVC na TPU mubikoresho byibicuruzwa byuzuye umwuka

Ubwiza bw’ibicuruzwa ahanini biterwa n’ibikoresho bikoreshwa mu kubikora. Ku bicuruzwa bishobora gukubura, ibikoresho bikunze kuvugwa ni PVC na TPU. Uyu munsi, tuzasobanura itandukaniro riri hagati y’ibyo bikoresho byombi.

Icya mbere, reka tubone igitangiriro gito kuri PVC. PVC ihagarariye polyvinyl chloride, polimeri ikomoka mu bikorwa. Umusaruro wa PVC mu nzira y’inganda watangiye nko mu myaka ya 1930, bikaba ibikoresho bikoreshwa cyane kandi bifite uburyo bwiza bwo gutunganya. Ibyiganjemo ibintu bishobora gutera kanseri, vinyl chloride (VCM), bya PVC nyuma y’imyiteguro ni bike, nta ngaruka ku buzima bw’abantu.

TPU, ku rundi ruhande, irashobora gufatwa nk’inyenyeri izamura ugereranije na PVC, kandi ikunze gukoreshwa nk’ikindi gisimbuza. TPU ihagarariye thermoplastic polyurethane elastomer, polimeri ikomoka mu bikorwa. Ariko, TPU izwiho kuba ikoreshwa mu buryo bukomeye, bigira akamaro kanini, kandi yabaye imwe mu bikoresho bya thermoplastic bikura vuba.

Ubungubu tumaze kuvuga amateka y’ibyo bikoresho byombi, reka dushingire ku itandukaniro ry’ingenzi mu bijyanye n’imiterere. PVC, nk’ikoreshwa mu buryo bwagutse, ifite ibyiza byinshi. Itanga ubushobozi bwiza bwo kuzitira amashanyarazi, bikaba byiza ku bikoresho bitanga ubushyuhe buke, kandi ifite imbaraga nziza zo guhagarara. Ariko, ibyangombwa byayo nabyo biratangwa. Ibicuruzwa bya PVC bikunze gutanga umunuko ukaze kandi usharya, kandi ntibishobora guhagarara neza mu bushyuhe. Gushyushya igihe kirekire bishobora gutera kubora, kugasohora gaze HCl no guhindura ibara rya PVC. Ku bw’ibyo, igikorwa cyayo gikegwa, n’ubushyuhe bukoreshwa busanzwe buva kuri -15°C kugeza kuri 55°C.

TPU ifite ibyangombwa byayo, nk’ubushobozi bubi bwo guhimbura na TPU isobanutse igenda ihinduka ibara ry’umuhondo uko igihe kigenda. Ariko, ayo makosa ntabwo atera ko byiza byayo bibura, bikaba byerekana impamvu TPU ari ugusimbuza PVC. TPU igaragaza imbaraga nyinshi zo gukubura, ubudodo, no guhagarara, bikayigira ikoreshwa mu buryo bwiza. Iruta izindi plastike mu bijyanye n’imbaraga, ubudodo, gukubura, guhagarara, kwanga amavuta, kwanga amazi, guhagarara, kwanga ikirere, n’ibindi. Byongeye, TPU itanga ubushobozi bwo kuzitira amazi, guhumeka, gukumira umuyaga, guhagarara, kwanga udukoko, kwanga ububibi, kuzitira, kwanga imirasire y’izuba, no kureka ingufu, hamwe n’ibindi byinshi.

Ibicuruzwa bitandukanye bisaba ibikoresho bikwiranye n’ibikoresho byabyo kugira ngo bibone imikorere myiza. Hamwe n’uburambe bw’imyaka irenga icumi mu bushakashatsi, iterambere, no gukora ibikoresho byo kwidagadura, dutanga ibicuruzwa byiza cyane bikundwa kw’isi yose kandi byiringirwa.
