Filimi ya TPU ifite ubushobozi bwo hejuru iyoboye udushya mu bikoresho by'ubuvuzi

Mu ikoranabuhanga ry’ubuvuzi rigenda ritera imbere cyane muri iki gihe, ibikoresho bya polymer byitwapolyurethane ikoresha thermoplastic (TPU)irimo guteza impinduramatwara mu buryo bucece. Filime ya TPU yaYantai Linghua New Material Co., Ltd.Iri kuba ingenzi cyane mu gukora ibikoresho by’ubuvuzi bigezweho bitewe n’imikorere yabyo myiza no kuba bihura neza n’ibinyabuzima. Iboneka ahantu hose, kuva ku masakoshi gakondo yo guterwamo imiti kugeza ku bikoresho bigezweho byo kwambara mu buzima.

1) Ikintu cy'ingenzi: Kuki inganda z'ubuvuzi zikunda TPU?
Filime ya TPUsi firime isanzwe ya pulasitiki. Ihuza ubushyuhe bwa plastike n'imbaraga za plastike, bigatuma habaho ubworoherane budasanzwe mu gushushanya ibikoresho by'ubuvuzi.
-Uburyo bwiza bwo guhuza umubiri n'umutekano: TPU yo mu rwego rw'ubuvuzi ikurikiza cyane amahame agenga uburinganire nka ISO 10993, irinda ko habaho ingaruka mbi cyangwa zitari uburozi iyo ikoze ku ngingo z'umubiri w'umuntu cyangwa amaraso, bigabanya cyane ibyago by'umurwayi.
-Imikorere myiza cyane ya mekanike: Filimi ya TPU ifite imbaraga nyinshi zo gukurura (ubusanzwe >30 MPa), uburebure bukabije mu gihe cyo kuruhuka (>500%), kandi irinda amarira neza (>30 kN/m), bigatuma igikoresho kiramba cyane kandi gishobora kwihanganira kunanura, guhinda no gukanda inshuro nyinshi nta kwangirika.
-Ubushuhe n'umwuka unyuramo: Imiterere y'imyobo cyangwa amazi ya firime ya TPU ituma umwuka w'amazi unyuramo neza mu gihe ubuza amazi n'udukoko. Ibi ni ingenzi cyane ku bikoresho byo gupfuka ibikomere n'imyenda yo kubaga, ishobora gutuma uruhu rwumuka, igatuma gukira, kandi ikongera ihumure ry'abakozi bo kwa muganga.
-Ikoraho neza cyane kandi ibonerana: Filimi ya TPU ifite imiterere yoroshye, ituma umubiri w'umuntu ugera neza kandi nta nkomyi; Ifite imiterere yoroshye yorohereza abaganga kureba uko ikoreshwa cyangwa gukira kw'ibikomere.
-Kurinda kwangiza: Filimi ya TPU ishobora kwihanganira uburyo butandukanye bwo kuvura indwara, harimo ethylene oxide (EO), imirasire ya gamma, n'imirasire ya electron, bigatuma ibintu bya nyuma bikomeza kuba bibi kandi bikagira umutekano.

2) Uburyo bwo gushyira mu bikorwa: Kuva ku buyobozi "butagaragara" kugeza ku rwego rw'ibanze rw'ubutasi
Ibi birangaFilime ya TPUbigira uruhare runini mu rwego rw'ubuvuzi:
-Uburyo bwo gutanga imiti mu buryo bwo kuyitera no kuyikoresha: Nk'ibikoresho by'imbere n'inyuma by'udukapu tw'imiti two mu rwego rwo hejuru, udukapu tw'imirire, n'udukapu twa dialysis yo mu nda, TPU yoroshye kandi idashobora gukaraba neza ituma umuti ukomeza guhagarara neza mu gihe cyo kuwutwara no kuwukoresha, kandi ubushobozi bwawo bworoshye bwo kugenzura ingano y'amazi.
-Ubuvuzi n'imitako yo kwita ku bikomere: Imitako mishya idapfa amazi kandi ishobora guhumeka hamwe na sisitemu zo kuvura ibikomere bidafite umuvuduko (NPWT) zikoresha cyane firime ya TPU. Ishobora gukuramo imyanda yo hanze no gukuraho ubushuhe mu gikomere, bigatuma igikomere gikira neza.
-Ibikoresho birinda kubagwa: bikoreshwa mu gukora ibyuma bihumeka kandi birwanya udukoko ku myenda yo kubaga, amakanzu yo kwitandukanya n'abandi, n'imyenda yo kwirinda, bitanga uburinzi bukomeye mu gihe bikemura ububabare bw'ibicuruzwa gakondo bidakoze mu myenda bidafite ububoshyi kandi bibabaza.
-Ibikoresho bishya byo kwa muganga: Filimi ya TPU yabaye ingenzi mu bikoresho bifasha mu kuvura indwara nka catheter z'imiti n'ibikoresho by'ubukorano bifasha umutima bitewe nuko ihura neza n'amaraso kandi ikagira ubworoherane. Byongeye kandi, mu bikoresho byo kwa muganga byambarwa nka patches nziza, Filimi ya TPU ikora nk'ikintu gifasha mu gukora ku ruhu, bigatuma igikoresho kirushaho kumererwa neza kandi kigakomeza kwizerwa.
3) Ishingiro ry'ubuziranenge: ibipimo by'ingenzi n'ibipimo ngenderwaho byo gupima
Kugira ngo buri cyiciro cya firime ya TPU cyujuje ibisabwa bikomeye mu buvuzi, turareba urukurikirane rw'amahame mpuzamahanga agize inkingi y'ubuziranenge bwayo:
-Imiterere ya mashini:
Ingufu zo gukurura no kurekura igihe cyo kuruhuka: ASTM D412 isanzwe ikoreshwa igenzura ko firime ifite imbaraga n'ubudahangarwa bihagije.
Ingufu z'amarira: ASTM D624 isanzwe ikoreshwa ipima ubushobozi bwayo bwo kurwanya amarira akwirakwira.
-Kuba ihuye n'ibinyabutabire: Ugomba gutsinda ikizamini gisanzwe cya ISO 10993, ari nacyo gisabwa kugira ngo umuntu yemererwe kwamamaza ibikoresho by'ubuvuzi.
-Imikorere y'imbogamizi:
Igipimo cy'ubushuhe bwo kohereza amazi mu kirere (WVTR): Amabwiriza nka ASTM E96 apima ubushobozi bwo kohereza amazi mu kirere, aho agaciro kayo kagaragaza ubushobozi bwo kohereza umwuka mu kirere.
Imiterere y'ibiziba by'amazi: amahame nka ASTM F1670/F1671 (akoreshwa mu gupima ubudahangarwa bw'amaraso y'ibikomoka ku bimera n'ubwandu bw'icyorezo).
-Imiterere y'umubiri:
Ubukomere: ASTM D2240 (Ubukomere bwo ku nkengero z'inyanja) ikunze gukoreshwa, naho TPU yo mu rwego rw'ubuvuzi ikoreshwa hagati ya 60A na 90A kugira ngo ikomeze koroha.
Icyerekezo cy'ejo hazaza: Igice Gishya mu Buhanga n'Iterambere Rirambye
4) Gutegereza ahazaza, amahirwe y'iterambere ryaFilime ya TPUmu rwego rw'ubuvuzi ni bigari kandi birasobanutse neza:
-Guhuza ubwenge: Mu gihe kizaza, filime za TPU zizahuzwa cyane n’ibikoresho by’ikoranabuhanga bito n’ibipima kugira ngo hakorwe "filime z’ubwenge" zishobora kugenzura ibipimo by’umubiri nk'umuvuduko w’umutima, isukari mu maraso, n’imiterere y’ibyuya mu gihe nyacyo, bigateza imbere iterambere ry’ubuvuzi bwihariye.
-TPU ishobora kubora: Bitewe n’uko abantu benshi barushaho gusobanukirwa ku bijyanye no kurengera ibidukikije, iterambere ry’ibikoresho bya TPU bishobora kugenzurwa no kwangirika cyangwa kwinjizwa n’umubiri w’umuntu mu mubiri bizaba icyerekezo cy’ingenzi cy’ibikoresho bishobora gushyirwa mu mubiri mu gihe kizaza, nka stent z’imitsi zishobora kwinjizwamo n’imisemburo yo mu mubiri.
-Guhindura imikorere y'ubuso: Mu guha firime za TPU imiti irwanya udukoko, imiti igabanya amaraso, cyangwa iteza imbere ubushobozi bwo gukura kw'uturemangingo binyuze mu ikoranabuhanga ryo hejuru, ikoreshwa ryabyo mu bikoresho byo mu rwego rwo hejuru no mu kuvura ibikomere bigoye bizarushaho kwaguka.

Yantai Linghua New Material Co., Ltd. yemera ko filime ya TPU yavuye ku 'bintu bisimbura' ikaba 'ibikoresho bitanga imbaraga'. Uruvange rw'imikorere yayo rudasanzwe rurimo gufungura urwego rushya rw'udushya mu bikoresho by'ubuvuzi. Ubu turi mu gihe cy'izahabu cy'iterambere ry'ubuvuzi rishingiye ku bumenyi bw'ibikoresho, kandi nta gushidikanya ko TPU ari imwe mu nyenyeri z'iki gihe.
