I-PTFE Emulsion Coated Fiberglass Fabric – Sintering Holding Time Izidingo

I-Sintering yisinyathelo esibalulekile lapho izinhlayiya ze-PTFE zincibilika, zigeleze, futhi zihlangane zibe ifilimu eqhubekayo, eminyene ehlangana ne-fiberglass substrate. Uma isikhathi sokubamba sifushane kakhulu, ukumboza kuhlala ku-porous futhi kubuthakathaka. Uma isikhathi eside kakhulu, i-PTFE iyehlisa isithunzi, ikhiphe amagesi anobuthi futhi iphenduke ibe brittle.

Ipharamitha eyisihluthulelo ibambe isikhathi - ubude besikhathi ngemuva kokuba inqwaba yokumboza ifinyelele izinga lokushisa le-sintering (ngokuvamile i-370-400 ° C). Lesi akusona nje isikhathi lapho isithando somlilo sisezingeni lokushisa; yisikhathi sokuthi Indwangu ngokwayo ingaphezu kwendawo yokuncibilika.

I-Aokai PTFE ithuthukise amapharamitha we-sintering emigqeni eminingi yomkhiqizo. Lo mhlahlandlela uhlanganisa izimfuneko zesikhathi sokubamba zezinhlobo ezihlukene zesithando somlilo, izici ezithonya umnyombo, kanye nokukhubazeka okuvela kusikhathi esingafanele.

Izimiso Eziyisisekelo – Okushiwo 'Ukubamba Isikhathi' Ngempela

1. Inhloso eyinhloko

Ukuvumela izinhlayiya ze-PTFE ukuthi zincibilike ngokugcwele, zigeleze, futhi zihlangane ngaphezu kwendawo yazo encibilikayo (cishe 327°C ), kwakheka ifilimu eqhubekayo neminyene efinyelela ukuhlangana okuqinile kwemishini ne-fiberglass substrate.

2. Umehluko obalulekile

Isikhathi sokubamba sisho ubude besikhathi obuqhubekayo ngemva kokuba inqwaba yokumboza ifinyelele izinga lokushisa le-sintering (ngokuvamile engu-370-400°C), kunokuba nje ubude besikhathi izinga lokushisa lomlilo lihlala lingashintshile.

Kubalulekile ukuqinisekisa ukuthi ukujiya okugcwele kwendwangu ye-fiberglass (kuhlanganise ne-resin evaleleke phakathi kwenqwaba ye-fiber yangaphakathi) ifinyelela izinga lokushisa elincibilikayo futhi ibambe isikhathi esanele. Izinga lokushisa elingaphezulu lodwa alanele - izingqimba zangaphakathi kufanele futhi zincibilike.

Ububanzi bereferensi bezinqubo ezijwayelekile

1. Isithando somlilo esiqhubekayo

Ukusethwa kwezinga lokushisa kwesithando somlilo: Ukushisisa kwezindawo eziningi ezinezinga lokushisa eliphezulu kusethelwe ku- 380-400°C (kufika ku-410°C ukwakheka okuthile okwenziwe ngendlela oyifisayo).

Isikhathi sokuhlala esisebenzayo (isikhathi sokubamba) endaweni enezinga lokushisa eliphezulu:

Ukulungiswa okungokoqobo: Tune isivinini somugqa ngokusekelwe kubude besithando somlilo - nciphisa isivinini sokuhamba kwendwangu ukuze unwebe isikhathi sokuhlala esisezingeni eliphezulu.

2. Iqoqo (uhlobo lwebhokisi) isithando somlilo esishisayo

Bamba izinga lokushisa elingashintshi ku- 380-390 ° C ngemuva kokushisa:

Isikhumbuzi: Izithando zamabhokisi zinenkinga yokusatshalaliswa kwezinga lokushisa elingalingani. Umoya ozungezayo onesivinini esiphezulu uyadingeka, futhi isikhathi sokubamba sizonwetshwa ngendlela efanele ukuze kugwenywe ukushona phansi kwezingqimba zangaphakathi.

Izinto Eziyinhloko Ezinquma Isikhathi sokubamba

Izinto eziyisihluthulelo ezinhlanu ziyasebenzisana ukuze kunqunywe isikhathi sokubamba esilungile sanoma yimuphi umkhiqizo othile.

1. Ukujiya kwendwangu ye-Fiberglass nesisindo

Izindwangu eziwugqinsi, ezisindayo zifaka ukungahambi kahle kwe-thermal futhi zidinga izikhathi zokubamba ezinde ukuze ukushisa kungene phakathi nendawo.

2. Amaphasi e-coating kanye nokulayisha kwe-PTFE

Izendlalelo eziningi zokumboza zidala amafilimu e-resin aminyene adinga ukufudumeza okunwetshiwe ukuze kuncibilike ngokugcwele ukunamathela okungaphansi. I-coating eyodwa emincane ivumela isikhathi sokubamba esifushane.

3. PTFE emulsion grade

• Ama-emulsions we-PTFE ahlanzekile - adinga amazinga okushisa aphezulu kanye nesikhathi esanele sokuhlala

• Izingxube eziguquliwe (ezixutshwe ne-PFA noma i-FEP) - zibonisa ukuncibilika okuphezulu futhi zivumele ukuncishiswa kwesikhathi sokubamba

4. Izinga lokushisa le-Sintering

• Amazinga okushisa asethiwe aphezulu (isb., 400°C) - finyeza isikhathi sokubamba esidingekayo

• Amazinga okushisa aseduze nomkhawulo ophansi (370°C) – adinga ukushisisa isikhathi eside

• Iwindi le -380-390°C lilinganisa ukusebenza kahle kokukhiqiza kanye nengozi yokuwohloka kwe-PTFE

5. Idizayini yesithando somlilo kanye nesivinini somoya oshisayo

• Amaziko anomoya oshisayo wesivinini esikhulu noma ukungena kwe-infrared - ukudlulisa ukushisa okusebenzayo, isikhathi sokubamba esifushane

• Iziko elithembele kuphela ekushisiseni okukhazimulayo - isikhathi sokuhlala esandisiwe siyadingeka

Ukukhubazeka Okubangelwa Isikhathi Esingafanele Ukubamba

1. Isikhathi esinganele sokubamba (under-sintering)

Ukutholwa: Ukuhlola okubonakalayo (okumhlophe okukhanyayo, okusanhlamvu), ukuhlolwa kokudonsa kwetheyiphu (ukucwecwa), ukuhlolwa kwesigaba esiphambanayo (izinhlayiya ezimhlophe ezingancibilikisiwe ngaphakathi).

2. Isikhathi eside kakhulu sokubamba (over-sintering)

Ukubona: Ukuhlola okubonakalayo (okuphuzi, izindawo ezishisayo), ukuhlolwa kokuqina (imifantu lapho igobile), ukuthola iphunga (iphunga elimuncu libonisa ukubola).

Amazinga Okuhlola Asebenzayo kanye Namathiphu Okuthuthukisa Inqubo

1. Sungula amajika esikhathi sokushisa

Sebenzisa i -tracker yezinga lokushisa lomlilo ukuze urekhode izinga lokushisa lendwangu yesikhathi sangempela futhi uqinisekise ubude besikhathi bokuncibilika obungaphezu kuka-370°C. Lena indlela ethembeke kakhulu yokuqinisekisa isikhathi sangempela sokubamba.

2. Ukuhlolwa kokuvuthwa okubonakalayo

I-PTFE ene-sintered ngokugcwele ikhona:

• Iyunifomu i-semi-transparent ukuya ekubonakaleni ngokuphelele (kuyahlukahluka ngokuqina)

• Azikho izinhlayiya ze-chalky ezingancibilikisiwe

• Iguquguqukayo ukuthinta (hhayi iqinile noma i-brittle)

3. Ukuhlolwa kokunamathela

Akukho ukuxebuka noma izinsalela zempushana ngemva kokuhlolwa kokudonsa kwetheyiphu noma ukugoba okuphindaphindiwe (goqa/uvule izikhathi ezingu-5-10).

4. Ukuhlola okulimazayo kwezigaba ezahlukene

I-Cut fabric cross-section ibonisa:

• Azikho izinhlayiya ezimhlophe ezingancibilikisiwe ngaphakathi

• Izintambo ze-Fiberglass zimanziswe ngokugcwele yinhlaka ye-PTFE encibilikisiwe

5. Izinyathelo zokuphepha nokupholisa ngempoqo

• Gcina umoya wokukhipha umoya onamandla ukuze uvimbele ukunqwabelana kwezinto ezinobuthi (perfluoroisobutylene, HF) ekuboleni kwe-PTFE

• Gcoba ngokuqinile izinga lokushisa eliphezulu kanye nesikhathi sokubamba

• Ngokushesha faka indwangu endaweni yokupholisa ephoqelekile ngemva kwesigaba sezinga lokushisa eliphezulu ukuze iphole ngaphansi kuka-300°C ngokushesha - ukupholisa okusheshayo kusiza ukukhiya ku-microstructure ehlanganisiwe.

Isifinyezo – Inkomba Esheshayo Yokubamba Isikhathi Umhlahlandlela

Umthetho ojwayelekile: Sebenzisa isikhathi esincane esamukelekile sokubamba esiqinisekisa ukuncibilika okuphelele kokunamathela, ukuleveli, kanye neziro zangaphakathi ezingancibilikisiwe - ukunciphisa ubungozi bokuwohloka kokushisa.
