PTFE High-Temperature Nsalu – Dip Single-Dip vs. Multi-Dip Impregnation Process

Nsalu ya PTFE yotentha kwambiri (PTFE-yokutidwa ndi fiberglass) ikhoza kupangidwa pogwiritsa ntchito njira ziwiri zosiyana: kulowetsera kumodzi ndi kulowetsedwa kochuluka . Kusankha pakati pawo kumatsimikizira makulidwe a zokutira, mtundu wa pamwamba, mulingo wa magwiridwe antchito, ndi mtengo.

Pakuviika kamodzi, nsalu ya fiberglass imadutsa mkombero umodzi wokha wa impregnation-drying-sintering. Munjira yothira mowirikiza, imadutsa mobwerezabwereza - nthawi zambiri 2-3 imayenda mpaka kupitilira khumi ndi awiri - kumanga PTFE wosanjikiza ndi wosanjikiza.

Aokai PTFE imagwiritsa ntchito njira zonse ziwiri kutengera kugwiritsa ntchito. Bukhuli likufotokoza tanthauzo, kayendedwe ka ndondomeko, makhalidwe, ndi machitidwe amtundu uliwonse, pamodzi ndi kufananitsa kwa machitidwe.

Njira Yolowetsera Pamodzi-Dip - Yachangu komanso Yotsika mtengo

1. Tanthauzo ndi kayendedwe ka ndondomeko

Tanthauzo: Nsalu ya Fiberglass imadutsa mkombero umodzi wokha wa impregnation-drying-sintering kuti ipange nsalu yomalizidwa ya PTFE.

Mayendedwe a ndondomeko:
Nsalu ya fiberglass → kulowetsedwa ndi PTFE kubalalitsidwa → kufinya-kuchoka/dotolo-tsamba lakuthwa kuti azitha kunyamula utomoni → kuyanika kocheperako pochotsa madzi → sintering yotentha kwambiri (360-400°C) kusungunula PTFE kukhala filimu yosalekeza → kuziziritsa ndi kumalizitsa.

2. Makhalidwe a ndondomeko

• Kujambula utomoni ndikochepa, kumapereka yopyapyala, yotsika galamala nsalu

• Maonekedwe opangidwa ndi fiberglass sangathe kudzazidwa mokwanira, zomwe zimapangitsa kuti pakhale malo okhwima okhala ndi mapini ang'onoang'ono

• Kusakwanira kwa PTFE kumabweretsa kutsika kwamphamvu kwamphamvu, mphamvu ya dielectric, kukana kulowa kwamankhwala, komanso kusagwira ndodo.

• Kuzungulira kopanga kumakhala kwakanthawi kochepa komanso kothandiza kwambiri komanso kutsika mtengo kwamtengo wapatali

3. Ntchito zofananira

Nsalu yoviika kamodzi imatengedwa kuti ikhale ndi zofunikira zochepa pa makulidwe, kusasunthika, komanso kusalala kwa pamwamba:

• Ma gaskets otsika-grade insulating

• Makasi osamata osakhalitsa

• Zipangizo zotha kulowa pang'ono zomwe zimasunga mpweya pang'ono

• Zosagwiritsa ntchito m'mafakitale pomwe mtengo ndiye woyendetsa wamkulu

Njira ya Multi-Dip Impregnation - Magwiridwe Osanjikiza-ndi-Layer Kumanga-Up

1. Tanthauzo ndi kayendedwe ka ndondomeko

Tanthauzo: Gawo laling'ono la fiberglass limadutsa mobwereza bwereza-kuyanika-sintering, nthawi zambiri kuyambira 2-3 kuthamanga mpaka kupitirira khumi ndi awiri. Chigawo chilichonse chotsatira chimayikidwa pa zokutira zomwe zilipo PTFE kuti zipange makulidwe, kudzaza zotsalira, ndi kukonza zolakwika zapamtunda.

Mayendedwe a ndondomeko:
Nsalu ya fiberglass → kuyanika koyamba → kuyanika → kuziziritsa → kuziziritsa → kuyamwitsa kachiwiri → kuyanika → kuziziritsa → kuziziritsa → kulowetsedwa kwachitatu … Kumangirira komaliza pamene makulidwe, galamala, ndi magwiridwe antchito akwaniritsidwa.

Kusintha kwa njira:

• Kuzungulira koyambirira: Kutsika kwakanthawi kochepa, kulowa kwambiri kwa PTFE kubalalitsidwa - kumalowerera mkati mwa mitolo ya fiber

• Pambuyo pake: Kukhuthala kwamphamvu kwambiri kapena kufalikira kolimba kwambiri - kumapanga makanema apamtunda ndikusindikiza ma pinholes.

2. Makhalidwe a ndondomeko

• Makulidwe ndi kutsitsa kwa PTFE kumatha kuyendetsedwa ndendende

• Gawo la PTFE limatha kufika 50-70% kapena kupitilira apo

• Kulowetsedwa kobwerezabwereza ndikudzaza mipata pakati pa ulusi wa ulusi ndikuchotsa mapini, kupereka zokutira zosalala, zophatikizika.

3. Kuchita bwino kwambiri

• Zabwino kwambiri zopanda ndodo ndi kumasula katundu

• Chapamwamba kukana mankhwala- dzimbiri ndi impermeability

• Kupititsa patsogolo mphamvu za dielectric komanso kusinthasintha kwa voliyumu

• Kukhazikika kokhazikika ndi kutentha kwanthawi yayitali mpaka 260 ° C

Kugulitsa: Kupanga nthawi yayitali yotsogolera, kugwiritsa ntchito mphamvu zambiri, kuwongolera mosamalitsa, komanso ndalama zopangira zambiri.

4. Ntchito zofananira

Nsalu zokhala ndi ma dip ambiri zimathandizira magawo apamwamba kwambiri, mafakitale apamwamba pomwe magwiridwe antchito amavomereza mtengo wake:

Kufananitsa Kofunikira Kwambiri - Mbali ndi Mbali

Chidule - Kusankha Njira Yoyenera Kufunsira Kwanu

Dip dip imodzi ndi njira yothamangira yopaka filimu yopyapyala yomwe imakhala ndi nthawi yayitali yopangira komanso yotsika mtengo, komabe imakhala yocheperako chifukwa chosakwanira bwino komanso chitetezo chochepa.

Multi-dip impregnation ndi njira yolowera-ndi-wosanjikiza komanso njira yomanga yomwe imatsekereza gawo lapansi la fiberglass. Imapanga nsalu yosalala, yowundana ya PTFE yokhala ndi magwiridwe antchito apamwamba kwambiri potengera zovuta zantchito komanso ndalama zambiri.

Aokai PTFE imapanga nsalu za PTFE za single-dip komanso zamitundu yambiri. Pazofunikira zamafakitale, pafupifupi nsalu zonse zapamwamba za PTFE-zopangidwa ndi fiberglass zimapangidwa kudzera munjira zambiri. Lumikizanani nafe kuti mukambirane kalasi yomwe ikugwirizana ndi zomwe mukufuna.

Zomwe zanenedwa pamwambapa zaukadaulo zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mungafune kudziwa zambiri zaukadaulo, milandu yogwiritsira ntchito ndi mayankho makonda pazotsatira zathu zonse, kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi yomatira ya PTFE, lamba wotentha kwambiri wa PTFE, lamba wosakanizira kutentha, lamba wambali imodzi PTFE, lamba wosatentha kwambiri, wosagwira magalasi osagwira chonde, osagwira magalasi osagwira chifukwa cha fiber. kudzera pamawu omwe ali pansipa:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Timamamatira ku malingaliro ofunikira a ukatswiri ndi kukhulupirika, odzipereka kuti apereke mayankho amtundu umodzi wamakampani komanso chisamaliro chamakasitomala!
