I-Medical-Grade PTFE High-Temperature Adhesive Tape - i-Biocompatibility kunye neSicelo sokuQapha

Kwimveliso yezixhobo zonyango, izixhobo zokuvala inzala, kunye nokugqunywa kwesixhobo sotyando, Iteyiphu encamathelayo ye-PTFE idlala indima ebalulekileyo. Kodwa xa iteyiphu inxibelelana nezigulana okanye indawo ezisingqongileyo, umbuzo omnye uba ngowona ubalulekileyo: ngaba ikhuselekile?

Iteyiphu yePTFE yodidi lwezonyango kufuneka ihlangabezane nemigangatho engqongqo ye-biocompatibility. I-PTFE substrate ngokwayo ine-inert ephezulu, kodwa i-adhesive, primer coatings, kunye neemeko zokucubungula zonke zichaphazela ukhuseleko jikelele.

I-Aokai PTFE ibonelela ngeteyiphu ye-PTFE yodidi lwezonyango ngamaxwebhu apheleleyo e-ISO 10993. Esi sikhokelo sibandakanya ukusebenza kwe-biocompatibility, izilumkiso zesicelo, kunye neengqwalasela ezibalulekileyo zokhuseleko.

Ukusebenza kwe-Biocompatibility - iSiseko soKhuseleko lweBanga lezoNyango

1. I-PTFE substrate – iyahambelana ngokwendalo

I-PTFE ibonakalisa ukunganyaniseki kweekhemikhali okungaqhelekanga, ukusabela ngokulambisa kuyo nayiphi na into kunye nokuxhathisa ukuthotywa. Ihambisa ngokwendalo iipropathi ezichasene ne-adhesive kunye ne-coefficient ephantsi ye-friction, ehlala i-biologically inert ngokuchasene nezicubu zomzimba kunye nolwelo ngaphandle kokubangela ukusabela kokwaliwa. Ibekwa phakathi kweepolymers kunye ne-biocompatibility eyaziwa kakhulu ukuza kuthi ga ngoku.

2. I-adhesive ye-silicone ye-Medical-grade - i-platinum-iphethwe

I-silicone yonyango enyangwa ngeplatinam ayinayo i-peroxide yokubola kweeproducts kwaye iyaziqhayisa nge-biocompatibility ephezulu. Isetyenziswa ngokubanzi kwiingubo zamanxeba, amabala eziva, kunye nokulungiswa kwezixhobo zonyango. Ukungabikho kwee-catalysts ezinobungozi kwenza ukuba kukulungele ukuqhagamshelana nolusu olude.

3. Umsebenzi obanzi ngokubanzi

Iteyiphu ye-PTFE yonyango esemgangathweni yenza ukuba akukho mvakalelo, ukucaphuka kwesikhumba, okanye i-cytotoxicity phantsi kobushushu obuqhelekileyo bokusebenza, kwaye ayikhuphi izinto ezinobungozi. Inokumelana nokuphindaphinda ubushushu obuphezulu bokuvala inzala ngaphandle kokuwohloka kwe-biocompatibility yayo.

Isilumkiso esibalulekileyo: Ukukhetha okungafanelekanga kwe-adhesives / primer coatings, okanye ukongezwa kwezongezo ezinobungozi ngexesha lokucubungula i-PTFE, kuya kuphazamisa kakhulu ukuhambelana kwe-biocompatibility. Ayizizo zonke iiteyiphu zePTFE ezibhalwe 'ubushushu obuphezulu' ezikhuselekileyo ngokwezonyango – soloko uqinisekisa ngamaxwebhu.

Izilumkiso eziBalulekileyo kwiSicelo

1. Ukuthobela ngokungqongqo umda wosetyenziso olucetywayo

Qinisekisa indawo yoqhagamshelwano ekujoliswe kuyo (ulusu olungaguqukiyo kuphela, ukungathanga ngqo kwe-mucosal / ukudibana kwegazi, okanye ukufakelwa) kunye nobude boqhagamshelwano (ixesha elifutshane, ixesha elide, okanye ukubonakaliswa okusisigxina). Ukunyaniseka kokhuseleko akunamsebenzi ukuba kusetyenziswe ngaphaya kwemida yovavanyo eqinisekisiweyo.

I-tape yonyango ye -Aokai PTFE iqinisekisiwe kwisikhumba esiqinileyo kunye noqhagamshelwano lwexesha elifutshane (≤24 iiyure). Ngolunye usetyenziso, dibana nomenzi.

2. Ungaze udlule kwimilinganiselo yokumelana nobushushu

Iteyiphu yobushushu obuphezulu be-PTFE ixhasa ubushushu benkonzo eqhubekayo ukuya kuthi ga kwi- 260°C . Amaqondo obushushu angaphaya kwe-300°C asenokuqalisa ukubola kwe-PTFE, ikhuphe iigesi ezinetyhefu ephezulu kuquka i-hydrogen fluoride kunye ne-perfluoroisobutylene.

Isilumkiso esikhethekileyo: Kwizixhobo zonyango ezifana ne-laser scalpels kunye neeyunithi ze-electrosurgical, ukufudumala kwendawo ngokukhawuleza kunokwenzeka. Nokuba ubushushu obuphakathi buphakathi kwemida, iindawo ezishushu zinokugqitha kuma-300°C. Sebenza ngokungqongqo ngokuhambelana nemida yokushisa enikezelwa ngumthengisi kwaye ubeke iliso langempela lobushushu bomphezulu.

Iindlela zoNzala – Landela IiNkqubo eziQinisekisiweyo kuphela

Uninzi lweeteyiphu zomgangatho wezonyango ziyahambelana neendlela ezininzi zokuvala inzala, kodwa nganye ineemfuno ezithile.

1. Uxinzelelo oluphezulu lokuvala inzalo yomphunga (121–134°C)

• Iyahambelana: Ewe (amanqaku amaninzi)

• Umjikelo: 15-30 imizuzu

• Qaphela: Imijikelo ephindaphindwayo inokunciphisa ngokuthe ngcembe amandla okuncamathela. Qinisekisa ukubalwa komjikelo nomenzi.

2. Ukwenziwa inzala kwe-ethylene oxide (EO).

• Iyahambelana: Ewe

• Imfuneko ebalulekileyo: Yenza i-aeration eyaneleyo yokuphelisa intsalela ye-carcinogenic ethylene oxide kunye ne-byproducts eyityhefu (ethylene chlorohydrin, ethylene glycol)

• Ixesha lokungenisa umoya: Ngokuqhelekileyo iintsuku ezi-7-14 ngokuxhomekeke kubushushu kunye nezinto eziphathekayo

3. Imitha yeGamma imitha

• Iyahambelana: Ilinganiselwe - isilumkiso esikhethekileyo siyafuneka

• Izilumkiso eziphambili:

  • I-Gamma irradiation inokwaphula amatyathanga emolekyuli e-PTFE, ibangele ukuqina

  • Ngamana ukuguqula i-silicone crosslinking density, ebangela i-adhesive partial adhesive delamination

  • Ubuninzi bedosi yesiqhelo ≤25 kGy (qinisekisa nomenzi)

  • Iidosi eziphezulu zinokujika itheyiphu ibe brittle kwaye ingasebenziseki

Ingcebiso ye-Aokai PTFE: Kwizicelo ezifuna inzala ye-gamma, cela idatha ethile yokuqinisekisa. Sinikezela ngamabakala azinzile kwi-gamma enonyamezelo lwedosi ebhaliweyo.

Qinisekisa uKhuseleko lwe-Adhesive kunye ne-Primer Coatings

Ezinye iiteyiphu zisebenzisa i-adhesive ye-acrylic okanye i-primer coatings equkethe izinyibilikisi eziphilayo. Qinisekisa ukuba umaleko wokuncamathelisa uyahlangabezana nemigangatho yezonyango, simahla:

• Iimonomers ezicaphukisayo ezishiyekileyo

• IiPlastiki (umz., iiphthalates)

• Iintsimbi ezinzima

Amaxwebhu afunekayo:

• Ingxelo esesikweni evela kumthengisi eqinisekisa ukungabikho kwe-BPA, latex, kunye ne-phthalates

• Isibhengezo sokwakheka kwezinto

• Idatha yovavanyo enokutsalwa kunye nevuzayo

Kulumkele uQhagamshelwano oluZinzileyo kunye naMayeza, ii-Acids ezinamandla, kunye neealkali

Nangona i-PTFE iziqhayisa ngokugqwesayo ukumelana neekhemikhali, ukuntywiliselwa ixesha elide kwizinyibilikisi ezithile eziphilayo okanye abathwali bamachiza kunokubangela:

• Ukudumba kwezinto

• Ukusilela kokuncamathelisa (i-delamination)

• Iintsalela zemizimba yangaphandle

Intshukumo: Yenza uvavanyo lokuhambelana kweekhemikhali xa uyila iityhubhu, izikhongozeli zokugcina, okanye izixhobo zendlela yolwelo.

Lawula uNyango loMphezulu kunye nokuSetywa kwamasuntswana

Kwiindawo zonyango ezicocekileyo kakhulu, ukuchithwa kwamasuntswana kuyinkxalabo ebalulekileyo.

• Ukuthintela imikrwelo: Musa ukusebenzisa izixhobo ezibukhali zokuphatha iteyiphu ngaphambi kokusetyenziswa - imikrwelo inokuvelisa amasuntswana kwaye idale iindawo zongcoliseko.

• Nciphisa i-debris: Xa usika iteyiphu, sebenzisa izikere ezicocekileyo okanye ii-automated cutters. Kuphephe ukukrazula ngesandla.

• Ngeenkqubo zongenelelo: Khetha iimveliso ezinemiphetho etywiniweyo engenathuli kunye nokukhutshwa kwamasuntswana aphantsi.

• Ukucoca kwangaphambi kwesicelo: Sula umphezulu ngelaphu elingena-lint elithotywe ngotywala be-isopropyl ukususa ukungcola ngaphambi kokufakwa.

Cela amaxwebhu okuThobela ngokuGqibeleleyo-Ngaphaya kweNgxelo yoVavanyo
