Impuzu ya TPU: Ibikorwa bishasha n'ibiranga ibikoresho vy'ubuhinga bushasha

Impuzu ya TPU (thermoplastique polyuréthane) ni impuzu ikora neza ikozwe mu mpuzu y’impuzu y’impuzu (TPU). Ivyo bihimba vyiza cane vy’umubiri, ukuntu bidahungabanya ibidukikije be n’ukuntu bikoreshwa mu buryo bwinshi, vyatumye abantu benshi bavyitaho mu myaka ya vuba mu bijanye n’impuzu, inganda be n’ubuvuzi.

I. Ibikoresho vy'ishimikiro n'uburyo bwo gukora impuzu ya TPU

TPU ni ikintu gikomeye gikozwe biciye mu gukorana n’ibindi bihimba vy’umubiri bita diisocyanate, polyol, n’ivyo kwagura uruzitiro. Ubuhinga bwayo bw'uruzitiro rw'amamolekule bufatanya ibice bikomeye (bitanga inkomezi) n'ibice bishobora guhinduka (bitanga ubushobozi bwo gukomera), bikaba bikora ubuhinga bwihariye "bw'ibice bikomeye n'ibiyoroshe". Ivyo bituma igitambaro ca TPU kigaragaza ubushobozi bwo gukomera cane, kidashobora gusenyuka, kandi kidashobora gutabuka mu bushuhe bwo mu cumba. Vyongeye, irashobora gukorwa biciye ku gukoresha ivyuma bifise ubushuhe (nk’ugutera inshinge, gusohora canke gutera ivyatsi) ku bushuhe bwinshi, iraguma ifise ishusho yayo iyo imaze gukonja, kandi irashobora gusubira gukoreshwa.

Impuzu za TPU zikoreshwa mu buryo bubiri: Ubwa mbere, amabuye ya TPU akoreshwa ata guca ku ruhande nk’ibikoresho vya mbere, akoreshwa biciye mu gupfuka, gupfuka, canke guzunguruka bikagira amafilime canke intsinga, ivyo bikaba bica bihurizwa hamwe n’ibindi bitambaro (nk’ugutera, gupfuka, canke guboha); ica kabiri, TPU iravangwa kandi igahindurwa n’ibindi bikoresho vy’ivyuma kugira ngo bibe vyiza cane (nk’akarorero, ubushobozi bwo guhangana n’amazi n’ubushobozi bwo guhangana n’imishwarara y’izuba).

II. Inyungu z'Ishingiro z'Ibikorwa: Guhuza Ibikorwa n'Ugukomera

Igihambaye mu guhiganwa kw'ibitambaro vya TPU biri mu bushobozi bwavyo bw'ingero nyinshi, harimwo:

Ivyiza vyinshi n’uguhinduka: TPU ifise ubushobozi bwo gukomera hagati y’ubw’umupira n’uw’impuzu, kandi ishobora kuramburwa gushika incuro nyinshi ku burebure bwayo bwa mbere n’ugusubirana ningoga, bikaba bituma ibereye ibikorwa bisaba guhuza n’umubiri w’umuntu canke gutwara umuzigo w’inguvu- (nk’akarorero, imyambaro y’imbere n’ibindi).

Ishobora guhangana n’ugushaza n’ugutabuka neza cane: Imigwi y’ibice vy’umubiri iri mu ruhererekane rwayo rw’ibihimba (nk’akarorero, urea na urethane) iratuma inguvu ziri hagati y’ibihimba vy’umubiri zikomera, ivyo bikaba bituma ishobora guhangana n’ugushaza birenze kure n’iyo ivy’imipira n’ivy’amapulasitike asanzwe. TPU iraguma ari intahemuka mbere n’igihe ikunda gutera canke ikorana n’ibintu bisongoye.

Ishobora gukingira amazi, irahumeka, kandi ishobora guhangana n’ibihe-Ishobora guhangana n’ibihe: Filime ya TPU ifise ubuhinga bufise amazi makeyi (ubunini bw’ibihengeri bugenzurwa biciye ku buryo budasanzwe) ibuza amazi kwinjira mu mazi (ibiharuro vy’amazi bishobora gukingira amazi birenze IPX7) mu gihe ireka amamoleke y’umwotsi w’amazi aca muri yo (ubushobozi bwo guca mu kirere bugera kuri g/02-502. amasaha). Akenshi ikoreshwa nk'"igipande kidashobora guterwa n'amazi, gishobora guhumeka" ku mpuzu zo hanze. Ikindi, itanga ubushuhe bwinshi bwo guhangana n’ubushuhe (igumya ubushobozi bwo gukomera kuva kuri -40℃gushika kuri 120℃) kandi irarusha cane ibikoresho vya kera nka PVC mu bijanye no guhangana n’ugukura kw’imishwarara ya UV.

Gukingira ibidukikije no gusubira gukoreshwa: TPU ni ikintu gishobora gusubirwamwo mu gushushanya inyuma yo gukurwamwo, bikagabanya imyanda y’ibikoresho. Ikindi kandi, uburyo bwo guhingura ibintu bugezweho bwagabanyije cane ivyuka biva mu bidukikije (VOC), bikaba vyubahiriza amategeko agenga ibidukikije nk’aya EU REACH.

III. Ibikorwa bisanzwe n'agaciro k'inganda

Ivyo bitambaro vya TPU bikora bituma biba ikintu nyamukuru mu mice myinshi:

Ivyuma vyo mu vyo gukina no hanze: Bikoreshwa mu bipande bitagira amazi kandi bishobora guhumeka, mu bipande vy’amakoti, mu bipande vyo kwambara yoga, no mu bipande vyo hejuru canke vyo mu mutwe vy’ibirato vyo gutemberamwo, bikaba bituma umuntu agira uburinganire n’uguhumurizwa.

Ibikoresho vy’ubuvuzi n’ivy’isuku: Bikoreshwa mu mpuzu zo kwikingira ubuvuzi (zibuza imigera n’amazi kwinjira mu mubiri), mu bikoresho vyo gufata amaso (bishobora gutambagira cane kandi bitagira -uburemere), no mu bikoresho vyo gupfunyika amataratara (bishobora guhumeka kandi bishobora kurwanya imigera).

Inganda n’Imiduga: Ikoreshwa nk’ibipfukisho vy’amazi, nk’ibipfukisho canke nk’ibipfukisho vy’imirongo, ikoresheje ubushobozi bwayo bwo guhangana n’amavuta n’imiti.

Ivyuma vy’ubuhinga bwa none: Bikoreshwa mu bikoresho vya telefone ngendanwa, mu bipfukisho vy’isaha y’ubwenge, no mu bindi bikoresho, TPU ishobora gukora ku mubiri canke ngo igwe, bituma umuntu ashobora kuyikoresha neza.

IV. Iterambere n'ingorane

Kubera iterambere mu buhinga bw’ibikoresho, ubushakashatsi n’iterambere ry’ibitambaro vya TPU biriko vyibanda ku gutandukanya ibikorwa (nk’imiterere y’imigera, ivy’ugutwara umuyagankuba, n’ivy’umuco) no ku buzima buramba (gutegura TPU ishingiye ku binyabuzima-, gusubirira ibikoresho vya peteroli n’amavuta y’ibimera). Ariko rero, igiciro cayo ni kinini cane kuruta ic’impuzu zisanzwe (nk’iyitwa polyester), kandi TPU zimwe zimwe zifise uburemere buke-zishobora gushikirwa n’uguhinduka kw’umuhondo canke zidashobora guhangana n’amazi, ivyo bikaba bisaba ko zikora neza kandi zigenzurwa neza.

Muri rusangi, imyenda ya TPU, kubera ubushobozi bwayo bwo guhingura ibintu n’ukuntu idahungabanya ibidukikije, yacitse ishami ry’ingenzi ry’ibikoresho vy’ubuhinga bwa none vy’amapolymere, ifise uruhara rudashobora gusubirizwa mu guteza imbere uguteza imbere imyenda ikora neza no guhindukira ikaja mu guhingura ivyatsi bitotahaye.
