Momwe Mungachotsere Zotsalira Zotsalira ndi Zinthu Zochepa Zomwe Zili ndi Mamolekyu Pakuphimba Panthawi Yopanga PTFE Kutentha Kwambiri Nsalu

Jiangsu Aokai Zida Zatsopano - PTFE Wopanga Nsalu Zotentha Kwambiri, amakuwonetsani momwe. Pakupanga nsalu zapamwamba za PTFE zotentha kwambiri, zowonjezera zotsalira ndi zinthu zochepa zamamolekyu mu zokutira ndizofunika kwambiri zomwe zimakhudza kutentha komaliza, kumasula katundu ndi chitetezo cha chakudya cha mankhwala. Kuonetsetsa kuti ntchito ya PTFE yotentha kwambiri ya nsalu ikugwirizana ndi miyezo, ndondomeko yolimba yamagulu ambiri ndiyofunikira kuchotsa zonyansazi.

Gawo Lalikulu: Kuyeretsa Kwachidziwitso Chachikulu cha PTFE Chophimba Chophimba Chotentha Kwambiri cha PTFE

Iyi ndiye njira yovuta kwambiri mu PTFE yotentha kwambiri yopanga nsalu, yomwe imakwaniritsa kulekanitsa kwakuthupi kwa zonyansa zokutira kudzera pakuwongolera kutentha.

Pambuyo PTFE emulsion impregnation wa PTFE mkulu kutentha nsalu gawo lapansi, mankhwala poyamba amalowa otsika kutentha kuyanika uvuni. Kwa filimu yonyowa pamtunda, kutentha kumayendetsedwa pa 240-285 ° C. Sitepe sikufuna kupanga ❖ kuyanika filimu, koma volatilize chinyezi, solvents ndi surfactants mu ❖ kuyanika mipata kudzera otentha mpweya. Kudumpha siteji iyi ndi mwachindunji kuchita mkulu-kutentha sintering kuchititsa pinholes kapena thovu padziko, kwambiri kuwononga compactness wa PTFE mkulu-kutentha nsalu.

Pambuyo pake, nsalu ya PTFE yotentha kwambiri imalowa m'dera la kutentha kwa 360-380 ° C. Pa kutentha uku, PTFE particles pamwamba kuyamba kusungunuka ndi kuyenda, kupanga mosalekeza zoteteza filimu. Panthawiyi, kutentha kumeneku pamwamba pa PTFE kusungunuka kumapereka mphamvu zokwanira za kinetic kwa oligomers otsalira ndi ma monomers osakhudzidwa mkati mwa zokutira kuti asungunuke ndikuthawa ku gawo lapansi. Kuwongolera molondola kwa kutentha kwa sintering ndikofunikira paukhondo wa nsalu ya PTFE yotentha kwambiri:

Kutentha kwapansi pa 360 ° C kumabweretsa kusokonezeka kosakwanira kwa zonyansa zamkati;

· Kutentha pamwamba pa 390 ° C kumayambitsa kuwonongeka ndi kuwonongeka kwa unyolo wa maselo a PTFE, kuwononga zokutira m'malo mwake.

Gawo Lachiwiri: Fine Process Control mu PTFE High-Temperature Cloth Production

Kuwonjezera pachimake matenthedwe mankhwala, kulamulira mwatsatanetsatane pa kupanga kumathandizanso kusintha ukhondo kalasi ya PTFE mkulu-kutentha nsalu.

· Substrate Pretreatment : Musanaphike, nsalu ya fiberglass yomwe imagwiritsidwa ntchito pansalu yotentha kwambiri ya PTFE imachotsedwa bwino ndi mankhwala a degumming. Zotsalira za organic pansalu yoyambira zidzatentha pakatentha kotsatira ndikukhalabe mu interlayer, kupanga zolakwika zomwe sizingathetsedwe.

· Auxiliary Cleaning : Pakuti PTFE mkulu-kutentha nsalu amafuna ukhondo mkulu, Intaneti kuyeretsa ndi enieni solvents kapena akupanga mankhwala angagwiritsidwe ntchito theka anamaliza mankhwala, utithandize kuchotsa pamwamba fumbi ndi processing mafuta madontho.

Gawo Lapamwamba: Njira Yowongolera Magwero a PTFE Kupanga Nsalu Zotentha Kwambiri za PTFE

Njira yabwino yoyeretsera ndikuchotsa zonyansa asanalowe mu dongosolo la mankhwala, zomwe zimafuna kuti ogulitsa nsalu a PTFE akhazikitse mfundo zoyendetsera magwero okhwima.

Kusankhidwa Kwazinthu Zamtundu Wapamwamba : Ma resin omwazika a PTFE okhala ndi chiyero chosachepera 99.9% okha ndi omwe ayenera kugwiritsidwa ntchito ngati zokutira zopangira. Ma resins otsika amakhala ndi zinthu zotsika kwambiri, zomwe zimapangitsa kuti zikhale zosatheka kupanga nsalu zoyenerera za PTFE zotentha kwambiri mosasamala kanthu kuti sintering imakonzedwa bwanji pambuyo pake.

Kuwongolera kwa Wothandizira Wothandizira : Pamene mafuta odzola kapena zoyezera zili zofunika popanga zokutira, mitundu yowira pang'ono, yosasunthika kwambiri idzasankhidwa, ndipo mlingo wawo ulamuliridwa mosamalitsa kuti zithetsedwe kwathunthu.

• Malo Opangira Ukhondo : Malo opangira zinthuwa azikhala ndi nkhawa komanso ukhondo. Zida zamkati zimakhala ndi PTFE kapena zopangidwa ndi zitsulo zosapanga dzimbiri kuti zisawononge fumbi ndi zinyalala zochokera ku chilengedwe kapena zida zowonongeka kuti zisagwere mufilimu yonyowa ndikupanga madontho onyansa amitundu mu zokutira.

Pakatikati pakuchotsa zinthu zotsalira mu zokutira za nsalu za PTFE zagona pakuwongolera bwino kutentha kwa sintering ndi kupindika kotentha. Pokhapokha pophatikiza mankhwala otenthetsera ndi kuwongolera kwathunthu kwaukhondo kumatha kuti nsalu yomalizidwa ya PTFE yotentha kwambiri imatha kubweretsa zinthu zabwino kwambiri zopanda ndodo, zosagwira kutentha komanso zotenthetsera kwambiri.

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

Kuti mudziwe zambiri, zochitika zamagwiritsidwe ntchito ndi mayankho makonda amtundu wathu wonse wamankhwala kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi ya PTFE yotentha kwambiri, lamba wa PTFE wotentha kwambiri, lamba wopanda waya wamakina omangira, nsalu imodzi ya PTFE, lamba wotenthetsera wotentha kwambiri, kulumikizana ndi magalasi omasuka, kulumikizana ndi magalasi omasuka, kulumikizana ndi magalasi aulere
