Kanema wochita bwino wa TPU amatsogolera kusinthika kwa zida zachipatala

Masiku ano ukadaulo wamankhwala womwe ukupita patsogolo mwachangu, zinthu za polima zimatchedwaThermoplastic polyurethane (TPU)mwakachetechete ukuyambitsa zipolowe. Mafilimu a TPUMalingaliro a kampani Yantai Linghua New Material Co., Ltd.ikukhala chinthu chofunikira kwambiri pakupanga zida zapamwamba zachipatala chifukwa chakuchita bwino komanso kugwirizanitsa kwachilengedwe. Kukhalapo kwake kuli ponseponse, kuyambira zikwama zachikhalidwe zolowetsera mpaka zida zathanzi zotsogola.

1) Mbali yayikulu: Chifukwa chiyani makampani azachipatala amakonda TPU?
filimu TPUsi filimu wamba ya pulasitiki. Imaphatikiza elasticity ya mphira ndi mphamvu ya pulasitiki, kupereka kusinthasintha kosayerekezeka kwa kapangidwe ka zida zamankhwala.
-Kukhazikika kwabwino kwachilengedwe ndi chitetezo: Gulu lachipatala TPU limatsatira mosamalitsa miyezo ya biocompatibility monga ISO 10993, kuwonetsetsa kuti palibe kukhudzidwa kapena kuchitapo kanthu kopanda poizoni mukakumana ndi minofu yamunthu kapena magazi, kumachepetsa kwambiri chiwopsezo cha odwala.
-Kuchita bwino kwamakina: Kanema wa TPU amakhala ndi mphamvu zolimba kwambiri (nthawi zambiri> 30 MPa), kutalika kwamphamvu kwambiri pakupuma (> 500%), komanso kukana misozi (> 30 kN/m), kupangitsa chidacho kukhala cholimba kwambiri komanso chotha kupirira kutambasula mobwerezabwereza, kupindika, ndi kupanikizana popanda kuwonongeka.
-Chinyezi ndi mpweya permeability: The porous kapena hydrophilic katundu wa TPU film amalola nthunzi wa madzi kudutsa momasuka pamene kutsekereza madzi amadzimadzi ndi mabakiteriya. Izi ndizofunikira kwambiri pakuvala mabala ndi zovala zodzitchinjiriza, zomwe zimatha kupangitsa khungu kukhala louma, kulimbikitsa machiritso, komanso kutonthoza ogwira ntchito zachipatala.
-Kukhudza kofewa komanso kuwonekera bwino: Kanema wa TPU ali ndi mawonekedwe ofewa, opatsa thupi la munthu momasuka komanso mopanda msoko; Kuwonekera kwake kwakukulu kumathandizira ogwira ntchito zachipatala kuti aziwona momwe kulowetsedwa kapena kuchira kwa bala.
-Sterilizability: Kanema wa TPU amatha kupirira njira zosiyanasiyana zoletsa kubereka, kuphatikiza ethylene oxide (EO), kuwala kwa gamma, ndi matabwa a ma elekitironi, kuwonetsetsa kuti sterility ndi chitetezo cha zinthu zomaliza.

2) Chiwonetsero chakugwiritsa ntchito: Kuchokera pachitetezo "chosaoneka" kupita kutsogolo kwanzeru
Makhalidwe awa afilimu TPUpangitsa kuti ziwonekere muzachipatala:
-Kulowetsedwa ndi dongosolo loperekera mankhwala: Monga zamkati ndi zakunja zosanjikiza zamatumba olowetsedwa okwera kwambiri, matumba a zakudya, ndi matumba a dialysis a peritoneal, kusinthasintha kwa TPU ndi kukana kutsekemera kumatsimikizira kukhazikika kwa yankho la mankhwala panthawi yoyendetsa ndikugwiritsa ntchito, ndipo kuwonekera kwake kumathandizira kuyang'ana kwamadzimadzi.
-Kusamalira mabala ndi kuvala: Zovala zatsopano zopanda madzi komanso zopumira komanso machitidwe olakwika oletsa mabala (NPWT) amagwiritsa ntchito kwambiri filimu ya TPU. Imatha kudzipatula bwino zoipitsa zakunja ndi kuchotsa chinyezi pabala, kupanga malo abwino ochiritsira chilonda.
-Zopangira zodzitchinjiriza: zomwe zimagwiritsidwa ntchito popanga zigawo zopumira komanso antibacterial pazovala zopangira opaleshoni, zovala zodzipatula, komanso zovala zodzitchinjiriza, zomwe zimapereka chitetezo chofunikira ndikuthana ndi zowawa zazinthu zachikhalidwe zosalukidwa zomwe zimakhala zodzaza komanso zosasangalatsa.
-Zida zamakono zamakono: Kanema wa TPU wakhala chinthu chofunika kwambiri pazida zothandizira monga ma catheter a baluni a mankhwala ndi zipangizo zothandizira mtima wopangira chifukwa cha kugwirizanitsa kwake kwa magazi komanso kusinthasintha. Kuphatikiza apo, pazida zamankhwala zovala ngati zigamba zanzeru, filimu ya TPU imagwira ntchito ngati gawo lapansi lolumikizana mwachindunji ndi khungu, kuonetsetsa chitonthozo ndi kudalirika kwanthawi yayitali kwa chipangizocho.
3) Mwala wapangodya wa khalidwe: magawo ofunikira ndi miyezo yoyesera
Kuwonetsetsa kuti gulu lililonse la filimu ya TPU likukwaniritsa zofunikira zachipatala, timatchula mndandanda wa miyezo yapadziko lonse yomwe imapanga maziko a khalidwe lake:
-Makina katundu:
Kulimba kwamphamvu komanso kutalika panthawi yopuma: Muyezo womwe umagwiritsidwa ntchito kwambiri wa ASTM D412 umatsimikizira kuti filimuyo ili ndi mphamvu zokwanira komanso kukhazikika.
Mphamvu yamisozi: Muyeso womwe umagwiritsidwa ntchito kwambiri wa ASTM D624 umayesa kuthekera kwake kukana kufalitsa misozi.
-Biocompatibility: Ayenera kupitilira mayeso okhazikika a ISO 10993, omwe ndi chofunikira pakuloleza kutsatsa kwa zida zamankhwala.
- Ntchito zotchinga:
Moisture Transmittance Rate (WVTR): Miyezo monga ASTM E96 imawerengera kuchuluka kwa nthunzi wake wamadzi, ndi mitengo yapamwamba yomwe ikuwonetsa mpweya wabwino.
Zinthu zotchinga zamadzimadzi: Miyezo monga ASTM F1670/F1671 (yomwe imagwiritsidwa ntchito poyesa kukana magazi opangidwa ndi ma virus).
-Makhalidwe athupi:
Kuuma: ASTM D2240 (Shore hardness) imagwiritsidwa ntchito nthawi zambiri, ndipo TPU yachipatala imakhala pakati pa 60A ndi 90A kuti ikhale yosinthasintha.
Future Outlook: Chaputala Chatsopano mu Intelligence and Sustainable Development
4) Kuyang'ana m'tsogolo, chiyembekezo cha chitukuko chafilimu TPUzachipatala ndi zazikulu komanso zomveka bwino:
-Kuphatikizika kwanzeru: M'tsogolomu, mafilimu a TPU adzaphatikizidwa mozama ndi ma microelectronics ndi masensa kuti apange "mafilimu anzeru" omwe amatha kuyang'anira magawo a thupi monga kugunda kwa mtima, shuga wa magazi, ndi kutuluka thukuta panthawi yeniyeni, kulimbikitsa chitukuko cha mankhwala opangidwa payekha.
-Biodegradable TPU: Ndi kuzindikira kochulukira kwa chitetezo cha chilengedwe, kupangidwa kwa zida za TPU zomwe zitha kuwongoleredwa kuti zinyozeke kapena kulowetsedwa ndi thupi la munthu mu vivo kudzakhala njira yayikulu ya m'badwo wotsatira wa zida zoyikira, monga ma stenting a vascular stenting ndi ma stents engineering.
-Kusintha kwapamwamba kwa ntchito: Popatsa mafilimu a TPU ndi antibacterial, anticoagulant, kapena kulimbikitsa mphamvu za kukula kwa maselo kudzera muukadaulo wapamwamba, kugwiritsa ntchito kwake mu implants zapamwamba komanso chithandizo cha mabala ovuta kudzakulitsidwanso.

Yantai Linghua New Material Co., Ltd. imakhulupirira kuti filimu ya TPU yakula kuchokera ku 'm'malo mwazinthu' kupita ku 'zinthu zopatsa mphamvu'. Kuphatikizika kwake kwapadera kumatsegula njira zatsopano zopangira zida zamankhwala. Pakali pano tili m'nthawi yabwino kwambiri yachipatala motsogozedwa ndi sayansi yazinthu, ndipo TPU mosakayikira ndi imodzi mwa nyenyezi zanthawi ino. ”
