Complete Industrial Production Njira ya PTFE Emulsion Impregnated Fiberglass Nsalu

Jiangsu Aokai New Materials, wopanga nsalu zotentha kwambiri za PTFE, amakutengerani zonse.

Nsalu ya PTFE yotentha kwambiri, yomwe imadziwika kuti polytetrafluoroethylene (PTFE) yokhala ndi magalasi a fiberglass , ndi chinthu chapadera kwambiri chopangidwa ndi polima. Kupanga kwake si njira yosavuta yopaka, koma njira yopangira matenthedwe ndi mankhwala. Kuti apange nsalu yapamwamba kwambiri ya PTFE yotentha kwambiri, ndondomeko yokhwima ya magawo anayi imafunika: kukonzekera nsalu yoyambira, kukonzekera njira yothetsera mimba, kuyika mimba ndi sintering, ndi pambuyo pa chithandizo..

Gawo 1: Kukonzekera Kwambiri kwa Nsalu Yoyambira

Gawoli limatsimikizira mphamvu zamakina ndi kukhulupirika kwadongosolo la nsalu yomaliza ya PTFE.

Thermal Cleaning (Dewaxing) Ulusi wa fiberglass womwe umagwiritsidwa ntchito kuluka nsalu za PTFE uli ndi organic sizing agents popanga. Ngati sichichotsedwa, othandizirawa amalepheretsa kumamatira kwa zokutira zotsatila za PTFE. Choncho, sitepe yoyamba ndiyo kudyetsa nsalu yoyambira mu ng'anjo yotentha kwambiri (pafupifupi 350 ° C) kuti iwonongeke mofulumira kuti iwonetsetse ukhondo wa gawo lapansi la fiberglass.

Kusintha Pamwamba Kuti mukhale ndi mphamvu zomangirira pakati pa fiberglass ndi PTFE zokutira utomoni, nsalu yoyambira imayikidwa ndi silane coupling agent. Izi zimakulitsa kwambiri mphamvu ya peel ya interlaminar ndikuletsa delamination kapena kupaka utoto pazomalizidwa.

Gawo 2: Kukonzekera kwa PTFE Impregnation Emulsion

Zomwe thupi ndi mankhwala a nsalu yomaliza zimatsimikiziridwa makamaka panthawiyi.

· Emulsion Kusakaniza The pachimake zopangira ndi anaikira PTFE kubalalitsidwa . Malinga ndi zofunikira zosiyanasiyana zogwiritsira ntchito - monga kuchita kwapamwamba kosamangirira kwa nsalu zophika chakudya kapena kukana kwambiri kuvala kwa nsalu zotulutsidwa - zodzaza ndi zowonjezera zimawonjezeredwa mu emulsion. The anakonza impregnation yankho n'kofunika kufotokoza kalasi ya yomalizidwa PTFE nsalu.

Gawo 3: Core Impregnation ndi Sintering

Iyi ndiye njira yofunika kwambiri yomwe imapatsa PTFE nsalu ya PTFE ntchito yake yapadera, nthawi zambiri imakhala yozungulira mobwerezabwereza.

Ma Impregnations Angapo Pansi pa kupsinjika kosalekeza, nsalu yoyambira pansi imadutsa mobwerezabwereza mu thanki yoviika yodzazidwa ndi emulsion ya PTFE. Kuti mukwaniritse makulidwe omwe mukufuna komanso kachulukidwe, mzere wopanga umatengera njira yozungulira: kuyimba → kuyanika → sintering . Kuzungulira kulikonse kumawonjezera kulemera kwa ❖ kuyanika.

Kuyanika Nsalu yopangidwa ndi theka-yomaliza imadutsa mu uvuni wotentha kwambiri (pafupifupi 100 ° C) kuti ichotse chinyezi. Kuwongolera kosayenera pakadali pano kumayambitsa thovu kapena mapini pa nthawi ya sintering, zomwe zimawononga kwambiri ntchito yotchinjiriza.

High-Temperature Sintering Ichi ndi mtima wa njira zopangira. Chophimba chonyowa chimatenthedwa pafupifupi 380 ° C, kulola kuti tinthu tating'onoting'ono ta PTFE tisungunuke ndikuyenda, ndikupanga filimu yoteteza kwambiri. Kuthekera kwa nsalu ya PTFE kupirira ntchito yayitali pa 260 ° C kumachokera ku polymer chain recrystallization mu sitepe iyi. Nsalu yosakwanira sintered imakonda kusweka ndi kutayika kwa zinthu zopanda ndodo.

Khwerero 4: Kuyang'anira Zamankhwala Pambuyo ndi Kumaliza

Pambuyo pa sintering, nsaluyo imadutsa njira zina zomaliza.

Kukhazikitsa kwa Hot-Press ndi Surface Treatment Nsalu za PTFE zapamwamba kwambiri (monga za malamba otumizira) zimasinthidwa kudzera m'ma roller otentha kuti aphwanye pamwamba ndikuchepetsa kupsinjika kwamkati. Pansalu za PTFE zomwe zimagwiritsidwa ntchito pamalaminates okhala ndi mkuwa wokwera kwambiri, chithandizo chapadera cha corona chimagwiritsidwa ntchito kuti chiwonjezeke kuuma.

Njira Yoyatsira Pazosefera zapamwamba kwambiri, kagawo kakang'ono kakang'ono ka polytetrafluoroethylene (ePTFE) kakang'ono kakang'ono kakang'ono kamakhala ndi laminated pamwamba, kupanga gulu losefera lokhala ndi kusefera kwapamwamba.

Aokai New Materials imagwiritsa ntchito kuwunika kokhazikika. Zogulitsa zomaliza zimayesedwa pogwiritsa ntchito grammage tester, high-voltage tester, ndi tensile tester. Zogulitsa zokhazokha zokhala ndi makulidwe a yunifolomu, zopanda ma pinholes, komanso zogwirizana ndi zofunikira za kukana kwamagetsi zomwe zimatulutsidwa ngati katundu woyenerera.

Zambiri pamwambapa zimaperekedwa ndi Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti mumve tsatanetsatane, zochitika zamagwiritsidwe ntchito ndi mayankho makonda azinthu zathu zonse - kuphatikiza nsalu za PTFE zotentha kwambiri, matepi a PTFE apamwamba, malamba a mesh a PTFE, malamba osasunthika okanikiza makina osindikizira, nsalu za PTFE zambali imodzi, zotchinga kutentha kwambiri, magalasi osamva kutentha kwambiri, magalasi opitilira muyeso - chonde tumizani magalasi owoneka bwino - chonde tumizani magalasi otetezedwa
