Itandukaniro riri hagati ya PVC na TPU mu bikoresho by’ibicuruzwa by’ifumbire

Ubwiza bw’ikintu bukunze guterwa n’ibikoresho bikoreshwa mu kubikora. Kubikoresho byo kuzura, ibikoresho bikunze kuvugwa ni PVC na TPU. Uyu munsi, tuzasobanura itandukaniro riri hagati y’ibyo bikoresho.

Icya mbere, reka dusobanure PVC. PVC isobanura polyvinyl chloride, ni polymer yakoze. Ubworozi bw’inganda bwa PVC bwatangiye mu myaka ya 1930, bikaba byaratumye ikoreshwa cyane kandi igahinduka ikoreshwa ry’ikoranabuhanga ryateye imbere. Ingano isigaye ya monomer ya vinyl chloride (VCM) yica kanseri muri PVC nyuma yo gutunganywa ni nkeya, ntabwo igira ingaruka ku buzima bw’abantu.

TPU, ukurikije ubundi buryo, irashobora gufatwa nk’inyenyeri izamuka ugereranije na PVC kandi ikunze gukoreshwa nk’ikintu cyazamuye ikindi. TPU isobanura thermoplastic polyurethane elastomer, polymer indi yakoze. Ariko, TPU izwiho kuba ikoreshwa ry’ibidukikije, ikoreshwa ryiza cyane rya polymer nshya kandi ikaba imwe mu bikoresho bya thermoplastic bikura byihuse.

Noneho tumaze gusobanura inkomoko y’ibyo bikoresho bibiri, reka dusuzume itandukaniro ry’ingenzi mu buryo bwabo. PVC, nk’ikintu cyakoreshejwe cyane, gifite ibyiza byinshi. Itanga ubushobozi bwiza bwo gukingira amashanyarazi, bikaba byiza kubikoresho byo gukingira amashanyarazi make, kandi ifite ubushobozi bwiza cyane mu buryo bw’imiti. Ariko, inenge zayo nazo zirabonwa. Ibikoresho bya PVC bikunze kumvikana umunuko ukaze, kandi bifite ubushobozi buke bwo kwihanganira ubushyuhe. Gushyushya igihe kirekire bishobora gutera kubora, gusohora gaze ya HCl no guhindura ibara rya PVC. Kubw’ibyo, urwego rw’ikoreshwa rwayo rurarebana, nk’ubushyuhe bw’akazi bukunze kuba hagati ya -15°C na 55°C.

TPU ifite inenge zayo ubwayo, nk’ubushobozi buke bwo gushingwa no gutera ubujiji bwa TPU itagaragara igihe kirekire. Ariko, izo nenge ntizituma ibyiza byayo bibura, kandi ni byo bisobanura kuki TPU ari ikintu cyiza cyo gusimbura PVC. TPU igaragaza ubushobozi bukabije bwo gukata, gukomeza, no kwihanganira gusaza, bikaba byarayigize ikoreshwa ry’ibidukikije ryizewe. Iruta izindi plastike mu bushobozi, ubukana, kwihanganira gusya, kwihanganira ubukonje, kwihanganira amavuta, kwihanganira amazi, kwihanganira gusaza, no kwihanganira ikirere. Byongeye, TPU itanga ubushobozi bwo gukingira amazi, ubushobozi bwo kwishyira ukuboko, gukingira umuyaga, kwihanganira ubukonje, gukuraho udukoko, kwihanganira ibyotsi, gukingira, kwihanganira imirasire ya UV, no kurekura ingufu, n’ibindi byinshi.

Ibikoresho bitandukanye bisaba ibikoresho bikwiye bitewe n’uburyo bwabyo kugira ngo bitange neza. Hamwe n’ubunararibone burenze imyaka icumi mu bushakashatsi, iterambere, no gukora ibikoresho byo kwidagadura, dutanga ibikoresho byiza cyane bikunzwe ku isi yose kandi byizewe.
