Kunwetshisiwe PTFE - I-Biomedical Polymer Material

I-polytetrafluoroethylene enwetshiwe (PTFE) iyinoveli ye-polymer yezokwelapha etholakala ku-polytetrafluoroethylene resin ngokusebenzisa ukwelula nezinye izindlela zokucubungula ezikhethekile. Inemvelo emhlophe, enwebekayo, futhi eguquguqukayo, enesakhiwo senethiwekhi esakhiwe ama-micro-fibers axhumene akha izimbotshana eziningi. Lesi sakhiwo esiyingqayizivele se-porous sivumela ukunwetshwa PTFE (ePTFE) ukugoba ngokukhululekile ngaphezu kuka-360° kuyilapho kukhombisa ukuhambisana kwegazi okuhle kakhulu kanye nokumelana nokuguga kwezinto eziphilayo. Ngenxa yalokho, ithola ukusetshenziswa okubanzi ekukhiqizeni imithambo yegazi yokwenziwa, amabala enhliziyo, neminye imikhiqizo ehlukahlukene yezokwelapha. Ngokombono wezokwelapha, imele indawo efanelekile yezicubu zebhayoloji ngenxa yokuvumelana kwayo okuyingqayizivele kanye nezakhiwo ezincane. Ngokuphawulekayo engenazo izinto ezinobuthi noma ezinomdlavuza kanye nemiphumela yokungezwani komzimba, amangqamuzana ezicubu zomuntu nemithambo yegazi angakhula abe ama-micropores ayo ukuze asungule ukuxhumana kwezicubu okufana nezicubu ezizimele.

Umsebenzi Wezokwelapha

Okunwetshiwe PTFE i-surgery soft tissue patch, eyaziwa nangokuthi i-e-PTFE isiqephu sokuhlinza, sakhiwe iketango elide lama-athomu ekhabhoni elimbozwe ama-athomu e-fluorine. Ukwakheka kwayo kwamangqamuzana okuyingqayizivele kuyinikeza ukuzinza okukhethekile ngokomzimba namakhemikhali, okuyenza ibe into yokwenziwa enezici eziphawulekayo. Ngaphezu kwalokho, ngemva kokufakwa ezingxenyeni ezihlukahlukene ezifana nemithambo yegazi yokwenziwa, ulwelwesi lwama-dural okwenziwa, namabala enhliziyo iminyaka engaphezu kwengu-40 nasezimweni zomtholampilo eziyizigidi ezingu-6, azikho izigameko zokwenqatshwa emtholampilo eziye zabikwa. Lobu bufakazi obuningi bubonisa ngokugcwele i-biocompatibility enhle kakhulu yale nto.

Isimiso Sokusebenza

Okunwetshiwe PTFE (ePTFE) ikhiqizwa kusuka ku-dispersion resin ye-polytetrafluoroethylene ngokusebenzisa amasu okucubungula akhethekile, okuholela ekwakhekeni kwe-ultrastructure ebonakala "ngokuhlangana nemicu." Ngokulawula ukuhlukana phakathi kwalezi zinhlaka, ukukhula kwangaphakathi kwamangqamuzana ezicubu kungase kushukunyiswe. Ngakho-ke, umehluko oyinhloko phakathi kokusebenzisa i-ePTFE njengento yokugcwalisa kanye nezinye izindlela zangaphambilini zilele endleleni yokuphulukisa izicubu. Ngokuqondile, ePTFE ikhuthaza ukuvuselelwa kwezicubu ngokukhula kwamaselula, kuyilapho irabha ye-silicone yendabuko isiza ukuphulukiswa nge-fiber encapsulation. Ngenxa yalokhu, izinqubo zokwandisa izicubu ezithambile ezisebenzisa le nto zinikeza izinzuzo ezifana nokuba ngokoqobo okuthuthukisiwe nokubukeka kwemvelo, ukugudluzwa okuncane kwezicubu zokwenziwa noma ukuwohloka, kanye nengozi encishisiwe yezinkinga. Ukwengeza, ngenxa yokungena okulinganiselwe kwezicubu zamangqamuzana kuma-micropores ayo, ukususwa kwezinto lapho kudingekile kuqondile.

Ukusetshenziswa kwezinkundla eziningi ze-e-PTFE

Indwangu yokusebenza okuphezulu

Umusho obuyekeziwe: Amafilimu e-GORE™ alula, aqinile, angangeni manzi, angangeni emoyeni futhi angacutshungulwa abe yizinhlobonhlobo zezindwangu ezikwazi ukungena ngaphakathi noma “eziphefumulayo”. Lokhu kubangela indwangu eyingqayizivele yokusebenza okuphezulu enikeza kokubili ukunethezeka nokuvikelwa. Ngokuhlangenwe nakho okubanzi emkhakheni wamafilimu amancane, i-GORE ikhiqiza inqwaba yama-laminates endwangu kuhlanganise nemikhiqizo eyaziwayo efana nezindwangu ze-GORE-TEX® kanye ne-WINDSTOPPER®. Lezi zindwangu zisetshenziswe kakhulu izisebenzi zezokwelapha, izicishamlilo, izisebenzi zezempi nezimo eziphuthumayo kanye nabantu abenza ukuhamba, ukushushuluza, ukuhamba ngebhayisikili, igalofu kanye neminye imisebenzi yangaphakathi / yangaphandle.

Ukufakelwa Kwezokwelapha

Ngenxa yokungangeni kwayo okumsulwa, kunwetshiwe PTFE (ePTFE) esetshenziswa emikhiqizweni yezokwelapha ye-GORE ibonisa ukuhambelana kwezinto eziphilayo okukhethekile futhi ayivezi noma iyiphi impendulo yokwenqatshwa emzimbeni. Isakhiwo esinama-microporous amaningi se-GORE ePTFE ivumela ukusetshenziswa kwayo ezixazululweni ezihlukahlukene zokuvuselela, njengemithambo yegazi yokwenziwa, izicubu ezithambile ezivuselela ukuvuselelwa kwezicubu, nezinsimbi zokuhlinza zokuhlinzwa kwemithambo, inhliziyo, okuvamile, nokuhlinzwa kwamathambo. Ngakho-ke, lokhu kuthuthukiswa kuzuzisa kokubili ochwepheshe bezokunakekelwa kwempilo kanye neziguli ngokuhlanganisa ngaphandle komthungo nenhlangano yemvelo yomzimba nokubuyisela ukusebenza okujwayelekile komzimba.

I-Fluorine equkethe i-Polymerisate Fiber

I-polytetrafluoroethylene enwetshiwe ka-Gore (isibPTFE) i-fiber inamandla amakhulu, ukushwabana okuncane, ukuguga okukhethekile nokumelana ne-UV, iqinisekisa ukuzinza nobuqotho bayo ngisho nasezimweni ezimbi kakhulu. Ukuguquguquka kwayo kwenza ukuthi ilukwe, iphothwe, ilukwe noma ithungelwe ezinhlobonhlobo zezindwangu ezihlanganisa izinto zokupakisha ezicindezelayo, izintambo zokuthunga, izindwangu zokwakha kanye nefloss yamazinyo.

Ama-Gaskets nama-Sealants

Okunwetshiwe PTFE (ePTFE) ikhombisa ukumelana namakhemikhali okuhle kakhulu, ukumelana nokugqokwa, kanye nokubekezelela izinga lokushisa eliphakeme neliphansi, okuyenza ifaneleke kakhulu ukuthuthwa kanye nokuvala uketshezi lwasezimbonini. I-GORE inikeza uhla lwamagasket kanye nezimpawu, okuhlanganisa amapuleti ayisicaba, imicu emincane, nama-sealant akheke ensimini atholakala ngamasayizi ahlukahlukene noma imininingwane yama-flange.

I-Industrial Film Technology

I-GORE enwetshiwe i-polytetrafluoroethylene (isibPTFE) amafilimu angacutshungulwa abe ama-microstructures ahlukahlukene ayingqayizivele ukuze akhiqize uchungechunge lwemidiya yokuhlunga esebenza kahle kakhulu enama-micropores avimba ngempumelelo izinhlayiya ezihlukahlukene kuyilapho evumela umoya ukuba udlule. I-inertness yamakhemikhali eyingqayizivele kanye nokuzinza kokushisa kwe-polytetrafluoroethylene enwetshiwe (ePTFE) ikwenze kube ukukhetha okuhle kwezinhlelo zokusebenza zokuhlunga ezibandakanya amakhemikhali anokhahlo namazinga okushisa aphezulu. I-GORE inikeza uhla olubanzi lokulawula ukungcola nezixazululo zokwelapha, okuhlanganisa izikhwama zokuhlunga, amabhokisi okuhlunga, amafilimu e-microfiltration, izimbobo zokuhlunga, nemikhiqizo ye-adsorption. Lezi zixazululo ezisezingeni lezimboni zithola ukusetshenziswa okubanzi emikhakheni eyahlukene efana nezitshalo zamakhemikhali, izishisi, izindawo zokukhiqiza ukudla nezidakamizwa, imisebenzi yokuphonsa, phakathi kokunye.

Izinto Ezithuthukisiwe ZeDielectric Zamadivayisi Kagesi

Ukulahlekelwa okungokwemvelo okuphansi kanye ne-dielectric constant yokunwetshwa PTFE (ePTFE) iyenze ibe yinto ekahle yokuvikela izintambo nezintambo. Isakhiwo sayo se-porous esiyingqayizivele sinciphisa ukulahlekelwa kwesignali nokuhlanekezela, kusiza ukudluliswa kwesivinini esiseduze kokukhanya kuyilapho kugcinwa ukuzinza okushisayo kanye nokuguquguquka kwemishini. Ngaphezu kwalokho, ePTFE inganciphisa ngempumelelo usayizi wokuxhumana okuphelele nesisindo, ikwenze kube into ephakathi yokugcwalisa evumayo. Uhlu olubanzi lwemikhiqizo ye-elekthronikhi ka-Gore, ehlanganisa izintambo zethusi kanye ne-fiber optic, izinhlelo zekhebula, izinto zebhodi lesifunda eziphrintiwe, imikhiqizo ye-conductive interface, kanye nama-gaskets okuvikela asetshenziswa kabanzi emikhakheni ehlukahlukene efunwa kakhulu efana nezokuxhumana, amakhompyutha, imishini yokuhlola neyokulinganisa, imboni yezokuvikela njenge kanye nezimakethe ze-aerospace.
