Itandukaniro riri hagati ya PVC na TPU mubikoresho byibicuruzwa byuzuye umwuka

Ubwiza bw’ibicuruzwa ahanini biterwa n’ibikoresho bikoreshwa mu kubikora. Ku bicuruzwa by’ibipfumye, ibikoresho bikunze kuvugwa ni PVC na TPU. Uyu munsi, tuzasobanura itandukaniro riri hagati y’ibi bikoresho bibiri.

Ubanza, reka duhimbire PVC mu ncamake. PVC isobanura polyvinyl chloride, polymer ikora. Umusaruro w’inganda za PVC watangiye nko mu myaka ya 1930, bigatuma ikoreshwa cyane hamwe n’ikoranabuhanga ry’ubuhanga. Ibisigazwa bya monomer ya vinyl chloride (VCM) itera kanseri muri PVC ni bike nyuma yo gutunganya, nta ngaruka mbi ku buzima bw’abantu.

TPU, ku rundi ruhande, irashobora gufatwa nk’inyenyeri izamuka ugereranije na PVC kandi ikoreshwa nk’ikindi gikoresho cyatejwe imbere. TPU isobanura thermoplastic polyurethane elastomer, polymer ikora indi. Ariko, TPU izwi nk’ikoresho rishya ry’ibidukikije, rikora neza kandi ryihuta, kandi ryabaye imwe mu bikoresho bya thermoplastic bikura byihuse.

Noneho tumaze gusobanura inkomoko y’ibi bikoresho bibiri, reka twinjire mu itandukaniro ry’ingenzi mu bijyanye n’imiterere. PVC, nk’ikoreshwa cyane, ifite byinshi byiza. Itanga amashanyarazi meza, bigatuma ikwiranye n’ibikoresho by’amashanyarazi make, kandi ifite ubushobozi bwiza bw’imiti. Ariko, inenge zayo nazo zirabona. Ibicuruzwa bya PVC akenshi bisohora impumuro ikaze kandi ifite ubushyuhe buke. Gushyushya igihe kirekire bishobora gutera kubora, gusohora gaze ya HCl no guhindura ibara rya PVC. Ku bw’ibyo, urwego rwayo rw’ikoreshwa ni ruto, hamwe n’ubushyuhe busanzwe bukora kuva -15°C kugeza 55°C.

TPU ifite inenge zayo, nko kudashobora gukora neza no kuba TPU isobanutse ikunda kuba umuhondo nyuma y’igihe. Ariko, izi nenge ntizica imbaraga zayo, zisobanura impamvu TPU ari ikindi gikoresho gikwiye PVC. TPU igaragaza imbaraga zidasanzwe, ubukana, no kurwanya gusaza, bigatuma ikoreshwa neza nk’ikoresho ry’ibidukikije. Iruta izindi plastike mu bijyanye n’imbaraga, ubukana, kurwanya guswera, kurwanya ubukonje, kurwanya amavuta, kurwanya amazi, kurwanya gusaza, no kurwanya ikirere. Byongeye, TPU itanga ubushobozi bwo kuzitira amazi, kwinjiza ubushuhe, kuzitira umuyaga, kurwanya ubukonje, antibakteriya, kurwanya agahomyo, insulasi, kurwanya imirasire y’izuba, no kurekura ingufu, hamwe n’ibindi byinshi byiza.

Ibicuruzwa bitandukanye bisaba ibikoresho bikwiye ukurikije ikoreshwa ryabyo kugira ngo bikore neza. Hamwe n’uburambe burenze imyaka icumi mu bushakashatsi, iterambere, no gukora ibikoresho by’imyidagaduro, dutanga ibicuruzwa byiza cyane bikundwa ku isi hose kandi byizewe.
