Polyurethane ya Thermoplastic (TPU) ntabwo ifite gusa imiterere ya rubber ya polyurethane ifatanye, nko gukomera cyane, kudapfa kwangirika cyane, ahubwo inafite imiterere ya thermoplastic y'ibikoresho bya polymeri bigororotse, ku buryo ikoreshwa ryayo rishobora kwaguka no mu butaka bwa pulasitiki. Cyane cyane mu myaka ya vuba aha, TPU yabaye imwe mu bikoresho bya polymeri byateye imbere vuba.
TPU ifite imbaraga nyinshi zo guhangana n’ubushyuhe bwinshi, imbaraga nyinshi, gukomera, no gusaza, bigatuma iba ibikoresho bikuze kandi bitangiza ibidukikije. Ifite imbaraga nyinshi, imbaraga nziza, imbaraga zidashobora kwangirika, imbaraga zidashobora gukonja, imbaraga zidashobora guterwa n’amavuta, imbaraga zidashobora gukurwaho n’amazi, imbaraga zidashobora gusaza, imbaraga zidashobora kugereranywa n’ibindi bikoresho bya pulasitiki. Muri icyo gihe, ifite imbaraga nyinshi zo kwinjira mu mazi no mu bushyuhe bwinshi, imbaraga zidashobora guhumeka, imbaraga zidashobora gukonja, imbaraga zirwanya bagiteri, imbaraga zidashobora gukururwa n’ibihumyo, n’imirimo myinshi myiza, nko kubungabunga ubushyuhe, imbaraga ziterwa n’imirasire y’izuba, n’imbaraga zikoreshwa mu gutanga ingufu.
TPU ifite ubushyuhe bwinshi bwo gukora. Ibicuruzwa byinshi bishobora gukoreshwa igihe kirekire hagati ya -40-80 ℃, kandi ubushyuhe bw'igihe gito bwo gukora bushobora kugera kuri 120 ℃. Ibice byoroshye mu miterere y'ibice bya TPU macromolecules bigena imikorere yabyo mu bushyuhe bwo hasi. TPU yo mu bwoko bwa poliyester ifite imikorere mike kandi yoroshye kurusha TPU yo mu bwoko bwa polyether. Imikorere ya TPU mu bushyuhe bwo hasi igenwa n'ubushyuhe bw'impinduka z'ikirahure bwa mbere bw'igice cyoroshye n'ubushyuhe bworoshye bw'igice cyoroshye. Intera y'impinduka z'ikirahure iterwa n'ibikubiye mu gice gikomeye n'urugero rw'itandukaniro ry'ibice byoroshye n'ibikomeye. Uko ibikubiye mu bice bikomeye byiyongera n'urugero rw'itandukaniro ry'ibice bikomeye bigabanuka, intera y'impinduka z'ibice byoroshye na yo iraguka uko bikwiye, bizatuma habaho imikorere mibi mu bushyuhe bwo hasi. Iyo polyether ikoreshwa nk'igice cyoroshye, imikorere ya TPU mu bushyuhe bwo hasi ishobora kunozwa. Iyo uburemere bwa molekile bw'igice cyoroshye bwiyongereye cyangwa TPU irasubitswe, urwego rwo kudahuza hagati y'ibice byoroshye n'ibikomeye narwo ruzagenda rwiyongera. Mu bushyuhe bwinshi, imikorere yayo ibungabungwa ahanini n'ibice by'iminyururu ikomeye, kandi uko ubukana bw'ibicuruzwa burushaho kwiyongera, niko ubushyuhe bwayo burushaho kwiyongera. Byongeye kandi, imikorere y'ubushyuhe bwinshi ntabwo ifitanye isano gusa n'ingano y'umunyururu, ahubwo inaterwa ingaruka n'ubwoko bw'umunyururu. Urugero, ubushyuhe bwa TPU buboneka hakoreshejwe (hydroxyethoxy) benzene nk'umunyururu buruta ubw'ubwa TPU buboneka hakoreshejwe butanediol cyangwa hexanediol nk'umunyururu. Ubwoko bwa diisocyanate bunagira ingaruka ku mikorere y'ubushyuhe bwinshi bwa TPU, kandi diisocyanate zitandukanye n'iminyururu myinshi kuko ibice bikomeye bigaragaza ahantu hatandukanye ho gushonga.
Muri iki gihe, uburyo bwo gukoresha filime ya TPU burimo kwaguka, kandi buri kugenda bukura buhoro buhoro kuva ku nkweto gakondo, imyenda, imyenda kugera ku byuma by’indege, ibya gisirikare, ibikoresho by’ikoranabuhanga n’ibindi. Muri icyo gihe, filime ya TPU ni ibikoresho bishya by’inganda bishobora guhindurwa buri gihe. Ishobora kwagura uburyo ikoreshwa binyuze mu guhindura ibikoresho fatizo, guhindura formula y’ibikoresho, kunoza uburyo ikorwa n’ubundi buryo, bityo igaha filime ya TPU umwanya munini wo kuyikoresha. Mu gihe kizaza, urwego rw’ikoranabuhanga mu nganda ruzarushaho kunozwa, kandi ikoreshwa rya TPU rizarushaho kuba ryiza.
Ni izihe serivisi zikoreshwa muri iki gihe mu bikoresho bya TPU muri sosiyete yacu?
Uko imodoka zigira uruhare runini mu buzima bwacu, ni ko abafite imodoka barushaho gukenera uburinzi bw'imodoka. Filimi yo kurinda irangi ry'ibikoresho bya TPU ni igisubizo cyiza cyo gukemura iki kibazo.
Kimwe mu biranga firime yo kurinda irangi ya TPU ni uko irwanya amarira neza, ishobora kurwanya ingaruka z'ibintu bityaye nk'amabuye n'umucanga mu muhanda, kandi ikarinda umubiri gushwanyagurika no gupfuka. Nta mpamvu yo guhangayikishwa n'ibyangirika bishobora kubaho mu gihe utwaye imodoka, kandi ushobora kwibanda cyane ku muhanda no ku bunararibonye bwo gutwara imodoka mu gihe utwaye imodoka.
Byongeye kandi, firime yo kurinda irangi ya TPU ifite ubushobozi bwo guhangana n’ikirere neza. Yaba izuba ryinshi, ingese y’imvura ivanze n’aside, cyangwa imyuka ihumanya, iyi firime yo kurinda irangi ishobora kurinda irangi ry’imodoka kwangirika, bigatuma imodoka ihora ifite isura nziza.
Igitangaje kurushaho ni uko firime yacu yo kurinda irangi ya TPU ifite ubushobozi bwo kwivura ubwayo. Iyo imaze gushwanyagurika gato, firime yayo ishobora kwisana ahantu hashyushye, bigatuma umubiri usubirana nk'uko byari bimeze mbere kandi ikamara igihe kirekire iyo firime yo kurinda irangi.
Iyi firime yo kurinda irangi y’ibikoresho bya TPU ntabwo itanga gusa uburinzi bwuzuye, ahubwo inashyira imbere cyane ku kurengera ibidukikije. Iyi firime yo kurinda irangi ikozwe mu bikoresho bitangiza ibidukikije ntabwo izateza umutwaro ku bidukikije, ibi bikaba bihuye no gushakisha ingendo zishingiye ku bidukikije ku bantu ba none.
Gutangiza firime yo kurinda irangi ry'ibikoresho bya TPU bigaragaza impinduka mu rwego rwo kurinda imodoka, bitanga ibisubizo bigezweho kandi byizewe ku burinzi ku batunze imodoka. Twakire uburinzi bw'icyatsi kibisi, reka imodoka zacu n'isi bihumeke hamwe.
