Itandukaniro riri hagati ya PVC na TPU mubikoresho byibikoresho byuzuye umwuka

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

Ubwa mbere, reka dusobanure mu ncamake PVC. PVC isobanura polyvinyl chloride, polymer ikorwa. Umusaruro w’inganda za PVC watangiye mu myaka ya 1930, bigatuma ikoreshwa cyane hamwe n’ikoranabuhanga ry’ubuhanga. Ibisigazwa bya monomer ya vinyl chloride (VCM) ibangamira ubuzima muri PVC ni bike nyuma yo gutunganywa, nta ngaruka 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 ikorwa. Ariko, TPU izwi nk’ikoresho rishya ry’ibidukikije, rikora neza kandi ryihuta, kandi ryabaye imwe mu bikoresho bya thermoplastic bikura vuba.

Noneho tumaze gusobanura inkomoko y’ibi bikoresho bibiri, reka twinjire mu itandukaniro ry’ingenzi mu bijyanye n’imiterere. PVC, nk’ikoresho rikoreshwa cyane, rifite ibyiza byinshi. Itanga ubushobozi bwiza bwo gukingira amashanyarazi, bigatuma ikwiranye n’ibikoresho byo gukingira inshuro nke, kandi ifite ubushobozi bwiza bwo guhagarara mu buryo bwa chimique. Ariko, inenge zayo nazo zirabaho. Ibicuruzwa bya PVC bikunze gusohora impumuro ikaze, kandi bifite ubushobozi buke bwo guhagarara mu bushyuhe. Gushyushya igihe kirekire bishobora gutera kubora, bisohora gaze ya HCl no guhindura ibara rya PVC. Ku bw’ibyo, urwego rw’ikoreshwa ryarwo rurarebana, hamwe n’ubushyuhe busanzwe bukora kuva -15°C kugeza 55°C.

TPU ifite inenge zayo, nk’ubushobozi buke bwo gukora neza no guhinduka umuhondo kubera igihe. Ariko, izi nenge ntizigomba gutesha agaciro imbaraga zayo, zisobanura impamvu TPU ari ikindi gikoresho gikwiye PVC. TPU yerekana ubushobozi bwihariye bwo gukomeza, gukomeza, no kurwanya gusaza, bigatuma ikoreshwa neza mu bidukikije. Iruta izindi plastike mu bijyanye n’imbaraga, gukomeza, kurwanya guswera, kurwanya ubukonje, kurwanya amavuta, kurwanya amazi, kurwanya gusaza, no kurwanya ikirere. Byongeye, TPU itanga ubushobozi bwo gukingira amazi, ubushobozi bwo kwinjiza ubushuhe, gukingira umuyaga, kurwanya ubukonje, imiterere yo kurwanya udukoko, kurwanya ibihumyo, gukingira, kurwanya imirasire ya UV, no gusohora ingufu, hamwe n’ibindi byinshi.

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 by’ubwiza bw’isonga bikundwa ku isi hose kandi byizerwa.
