Sekhahla sa Bongaka sa PTFE High-Temperature Adhesive Tape - Biocompatibility and Application Precautions

Ha ho etsoa lisebelisoa tsa bongaka, lisebelisoa tsa sterilization, le lisebelisoa tsa ho buoa, Theipi ea sekhomaretsi ea PTFE e bapala karolo ea bohlokoa. Empa ha theipi e kopana le bakuli kapa libaka tse sa hloekang, potso e le 'ngoe e ba ea bohlokoa: na e bolokehile?

Theipi ea PTFE ea boemo ba bongaka e tlameha ho fihlela litekanyetso tse thata tsa biocompatibility. The PTFE substrate ka boeona e na le inert haholo, empa sekhomaretsi, li-primer coatings, le maemo a ts'ebetso li ama ts'ireletso ka kakaretso.

Aokai PTFE e fana ka teipi ea boemo ba bongaka ba PTFE e nang le litokomane tse felletseng tsa ISO 10993. Tataiso ena e akaretsa ts'ebetso ea biocompatibility, litemoso tsa ts'ebeliso, le lintlha tsa bohlokoa tsa polokeho.

Ts'ebetso ea Biocompatibility - Motheo oa Tšireletseho ea Bongaka ba Bongaka

1. PTFE substrate – biocompatible ka tlhaho

PTFE e na le boits'oaro bo ikhethang ba lik'hemik'hale, ha e sebetsane le ntho leha e le efe le ho hana ho senyeha. Ka tlhaho e fana ka thepa e khahlanong le sekhomaretsi le coefficient e tlase ea khohlano, e sala e sa sebetse ka biologically khahlano le lisele tsa 'mele le maro ntle le ho tsosa maikutlo a ho hana. E maemong a har'a li-polymer tse nang le biocompatibility e tsebahalang haholo ho fihlela joale.

2. Sekhomaretsi sa silicone sa boemo ba bongaka - se phekoloa ka platinum

Silicone ea bongaka e phekotsoeng ka platinamu ha e na lihlahisoa tse bolang tsa peroxide ebile e ithorisa ka ho lumellana ha lintho tse phelang. E sebelisoa haholo ho roala maqeba, maqeba a maqeba, le ho lokisa lisebelisoa tsa bongaka. Ho ba sieo ha li-catalyst tse kotsi ho etsa hore e tšoanelehe bakeng sa ho kopana ha letlalo nako e telele.

3. Kakaretso e akaretsang tshebetso

Theipi e tšoanelehang ea boemo ba bongaka ba PTFE ha e khothaletse, ho teneha ha letlalo, kapa cytotoxicity tlas'a mocheso o tloaelehileng oa ts'ebetso, 'me ha e lokolle lintho tse kotsi. E khona ho mamella ho thibela likokoana-hloko khafetsa ntle le ho senyeha ha biocompatibility ea eona.

Tlhokomeliso e Bohlokoa: Khetho e fosahetseng ea li-adhesives / primer coatings, kapa ho eketsoa ha li-additives tse kotsi nakong ea ts'ebetso ea PTFE, e tla senya biocompatibility haholo. Ha se litheipi tsohle tsa PTFE tse ngotsoeng 'mocheso o phahameng' tse bolokehileng ho tsa bongaka - ka linako tsohle netefatsa ka litokomane.

Litlhokomelo tse Bohlokoa bakeng sa Kopo

1. Ikamahanye ka thata le boholo ba tšebeliso e reriloeng

Netefatsa sebaka seo u batlang ho ikopanya le sona (letlalo le sa tsitsang feela, ho kopana ha mali ka tsela e sa tobang, kapa ho kengoa) le nako ea ho ikopanya (ho pepesehela nako e khuts'oane, nako e telele kapa ho sa feleng). Botšepehi ba polokeho ha bo na thuso haeba bo sebelisoa ho feta tekanyo e netefalitsoeng ea teko.

Theipi ea bongaka ea Aokai PTFE e netefalitsoe bakeng sa letlalo le tsitsitseng le ho kopana ha nako e khutšoanyane (≤24 lihora). Bakeng sa lits'ebetso tse ling, ikopanye le moetsi.

2. Le ka mohla u se ke ua feta meeli ea ho hanyetsa mocheso

Theipi ea PTFE ea mocheso o phahameng e tšehetsa mocheso o tsoelang pele oa tšebeletso ho fihlela ho 260°C . Dithempereichara tse fetang 300°C di ka tsosa PTFE ho bola, ho ntsha digase tse chefo haholo ho kenyeletswa hydrogen fluoride le perfluoroisobutylene.

Tlhokomeliso e khethehileng: Lisebelisoa tsa bongaka tse kang laser scalpels le electrosurgical units, hang-hang ho chesa ho feteletseng ho ka etsahala. Le haeba mocheso o tloaelehileng o le ka har'a meeli, libaka tse chesang li ka feta 300°C. Sebetsa ka thata ho latela meeli ea mocheso e fanoeng ke mofani oa thepa le ho hlahloba mocheso oa sebele oa holim'a metsi.

Mekhoa ea ho Sterilization - Latela Mekhoa e Tiisitsoeng Feela

Litheipi tse ngata tsa boemo ba bongaka li lumellana le mekhoa e mengata ea ho thibela likokoana-hloko, empa e 'ngoe le e' ngoe e na le litlhoko tse khethehileng.

1. Ho thibela metsi ka khatello e phahameng (121–134°C)

• E lumellana: E (limaraka tse ngata)

• Potoloho: 15-30 metsotso

• Tlhokomeliso: Lipotoloho tse phetoang hangata li ka fokotsa matla a sekhomaretsi butle-butle. Netefatsa palo ea potoloho le moetsi.

2. Ethylene oxide (EO) sterilization

• E lumellana: E

• Tlhokahalo ea bohlokoa: Etsa moea o lekaneng ho felisa mesaletsa ea carcinogenic ethylene oxide le lihlahisoa tsa eona tse chefo (ethylene chlorohydrin, ethylene glycol)

• Nako ea moea: Ka tloaelo matsatsi a 7-14 ho latela mocheso le thepa

3. Ho khantša mahlaseli a gamma

• E lumellana: E lekanyelitsoe - ho hlokahala tlhokomeliso e khethehileng

• Litlhokomeliso tsa bohlokoa:

  • Mahlaseli a Gamma a ka roba liketane tsa limolek'hule tsa PTFE, tsa baka ho putlama

  • E ka fetola boima ba silicone crosslinking, e bakang karolo e itseng ea sekhomaretsi delamination

  • Tekanyo e phahameng ka ho fetesisa ke ≤25 kGy (bonahala le moetsi)

  • Litekanyo tse phahameng li ka fetola tepi hore e be brittle 'me e se ke ea sebelisoa

Keletso ea Aokai PTFE: Bakeng sa lits'ebetso tse hlokang ho etsoa ho thibela likokoana-hloko ka gamma, kopa lintlha tse khethehileng tsa netefatso. Re fana ka limaraka tse tsitsitseng tsa gamma tse nang le mamello ea litekanyetso tse tlalehiloeng.

Netefatsa Tšireletseho ea Sekhomaretsi le Liaparo tsa Primer

Litheipi tse ling li sebelisa sekhomaretsi sa acrylic kapa li-primer tse nang le li-solvents. Netefatsa hore lera la sekhomaretsi le kopana le litekanyetso tsa bongaka, ntle le:

• Li-monomers tse setseng tse halefisang

• Lisebelisoa tsa polasetiki (mohlala, phthalates)

• Litšepe tse boima

Litokomane tse hlokahalang:

• Polelo ea semmuso e tsoang ho morekisi e netefatsang bosieo ba BPA, latex le phthalates

• Phatlalatso ea sebopeho sa thepa

• Lintlha tsa tlhahlobo ea lintho tse ka ntšitsoeng le tse fumanehang

Qoba ho Kopana le Meriana, Li-Acids tse Matla, le Alkalis

Leha PTFE e ithorisa ka khanyetso ea lik'hemik'hale e ikhethang, ho qoelisoa ka nako e telele ho lihlapolli tse itseng tsa tlhaho kapa lijari tsa lithethefatsi ho ka baka:

• Ho ruruha lintho tse bonahalang

• Ho hloleha ho khomarela (delamination)

• Masalla a mmele a kantle

Ketso: Etsa tlhahlobo ea tšebelisano ea lik'hemik'hale ha u rala li-tubing, lijana tsa polokelo, kapa lisebelisoa tsa tsela ea mokelikeli.

Laola Kalafo ea Bokaholimo le Ho Tsoa ha Particle

Libakeng tsa bongaka tse hloekileng ka ho fetesisa, tšollo ea likaroloana ke taba ea bohlokoa haholo.

• Thibela mengoapo: U se ke ua sebelisa lisebelisoa tse bohale ho tšoara theipi pele u sebelisoa - mengoapo e ka hlahisa likaroloana 'me ea etsa libaka tsa tšilafalo.

• Fokotsa lithōle: Ha u seha teipi, sebelisa sekere se hloekileng kapa li-cutters tse iketsetsang. Qoba ho tabola ka letsoho.

• Bakeng sa mekhoa ea ho kenella: Khetha lihlahisoa tse nang le likarolo tse tiisitsoeng tse se nang lerōle le tlhahiso e tlase ea likaroloana.

• Ho hloekisa pele ho kopo: Hlakola bokaholimo ka lesela le se nang lint le kolobisitsoeng ka joala ba isopropyl ho tlosa litšila pele o sebelisoa.

Kopa Tokomane e Felletseng ea Tumellano - Ka Ntle ho Tlaleho ea Teko

Tlaleho e ikemetseng ea tlhahlobo ea biocompatibility ha ea lekana. Aokai PTFE e khothaletsa ho laela mofani oa thepa ho fana ka:

Aokai PTFE e fana ka liphutheloana tse felletseng tsa litokomane ka thomello eohle ea theipi ea boemo ba bongaka. Hape re ka ts'ehetsa litlatsetso tsa taolo ka lifaele tse felletseng tsa tekheniki.

Kakaretso - Lethathamo la Khetho ea Litheipi tsa Bongaka tsa PTFE

Aokai PTFE e fana ka theipi ea boemo ba bongaka ba PTFE e nang le litokomane tse felletseng tsa ISO 10993 le tšehetso ea netefatso ea ho hloka matla. Ikopanye le rona bakeng sa lifaele tsa tekheniki le likopo tsa sampole.

Tokomane ena ea tekheniki e fanoa ke Jiangsu Aokai New Materials Technology Co., Ltd.

Haeba o hloka lintlha tse qaqileng, linyeoe tsa kopo le litharollo tse hlophisitsoeng bakeng sa lihlahisoa tsa rona tse feletseng tse kenyelletsang masela a PTFE a mocheso o phahameng oa mocheso, litheipi tsa bongaka tsa PTFE tse phahameng tsa mocheso, PTFE mabanta a mocheso o phahameng oa mocheso, mabanta a seamless laminator, lesela le le leng le le leng la PTFE, mabanta a conveyor a phahameng a mocheso le mocheso o ka tlaase ho rona:
