Yakazara Indasitiri Kugadzira Maitiro ePTFE Emulsion Impregnated Fiberglass Mucheka

Jiangsu Aokai Zvitsva Zvishandiso, PTFE inogadzira machira epamusoro-tembiricha, inokutora iwe mukuita kwakazara.

PTFE high-temperature jira, kemikari inozivikanwa sepolytetrafluoroethylene (PTFE) yakavharidzirwa fiberglass jira , chinhu chakatanhamara chepolymer chinoumbwa. Kugadzirwa kwayo hakusi nyore kupfekedza nzira, asi yakanyanyisa kupisa uye makemikari ekurapa system. Kugadzira jira repamusoro-soro rePTFE, danho rechina rakasimba rinodiwa: kugadzirira kwejira rekutanga, kugadzirira kwekugadzirisa gadziriso, core impregnation uye sintering, uye mushure mekurapa..

Danho 1: Pretreatment yeBase Fabric

Iyi nhanho inosarudza simba remagetsi uye kuvimbika kwechimiro chekupedzisira PTFE jira.

Thermal Cleaning (Dewaxing) Iyo fiberglass yarn inoshandiswa kuruka PTFE jira rine organic saiziing agents panguva yekugadzira. Kana isina kubviswa, maajenti aya anokanganisa zvakanyanya kunamatira kweanotevera PTFE machira. Nokudaro, danho rokutanga nderokudyisa jira rekutanga muchoto chepamusoro-soro (inenge 350 ° C) kuitira kukurumidza kudonha kuti uve nechokwadi chekuchena kwefiberglass substrate.

Kugadziriswa Kwepamusoro Kuti uvandudze simba rekubatanidza pakati pefiberglass nePTFE coating resin, jira repagadziko rinobatwa nesilane coupling agent. Iyi nhanho inosimudzira zvakanyanya interlaminar peel simba uye inodzivirira delamination kana coating peeling muchigadzirwa chakapedzwa.

Nhanho 2: Kugadzirira kwePTFE Impregnation Emulsion

Izvo zvemuviri uye zvemakemikari zvimiro zvejira rekupedzisira zvinonyanya kutsanangurwa panguva ino.

· Emulsion Kusanganisa Iyo yakakosha mbishi zvinhu yakanyura PTFE kupararira . Zvinoenderana nezvinodiwa zvakasiyana-siyana zvekushandisa - senge yakakwira isiri-tsvimbo kuita kwemachira ekubikisa chikafu kana yakakwira kupfeka kuramba kwemachira ekuburitsa - mafirita uye ekuwedzera anowedzerwa mu emulsion. Iyo yakagadziriswa impregnation solution yakakosha pakutsanangura giredhi rejira rakapedzwa rePTFE.

Danho rechitatu: Core Impregnation uye Sintering

Iyi ndiyo nzira yakakosha inopa PTFE jira rayo rakasiyana kuita, rinowanzobatanidza kudzokororwa kutenderera.

Multiple Impregnations Pasi pesimba rinoramba richidzorwa, iyo pretreated base jira rinopfuura kakawanda kuburikidza nedhipi tank yakazadzwa nePTFE emulsion. Kuti uwane ukobvu hunodiwa uye kuwanda, mutsetse wekugadzira unotora cyclic maitiro: impregnation → kuomesa → sintering . Kutenderera kwega kwega kunowedzera huremu hwekuputira.

Kuomesa Mucheka wakaiswa semi-wakapedza unopfuura nepakati pevheni yekupisa (inenge 100 ° C) kuti ibvise unyoro zvinyoro. Kudzora kwakashata panguva ino kunokonzeresa mabubbles kana pinholes panguva yekupisa, zvinoshatisa zvakanyanya kuita kwekuisa insulation.

High-Temperature Sintering Uyu ndiwo moyo wekugadzira maitiro. Iyo yakanyorova yekuputira inotungidzirwa paanenge 380 ° C, ichibvumira PTFE zvimedu kuti zvinyunguduke zvizere uye kuyerera, zvichigadzira dense inodzivirira firimu. Kugona kwejira rePTFE kutsungirira sevhisi yenguva refu pa260 ° C kunobva ku polymer cheni recrystallization mudanho iri. Mucheka usina kukwana sintered unowanzoita kuputika uye kurasikirwa kwezvinhu zvisiri-tsvimbo.

Nhanho 4: Kurapa-Kurapwa uye Kupedzwa Kuongororwa Kwechigadzirwa

Mushure mekupisa, jira rinopinda mamwe maitiro ekupedzisa.

Hot-Press Setting uye Surface Treatment High-end PTFE machira (akadai seaya emabhandi ekutakurisa) anoiswa calender kuburikidza neanopisa rollers kuti apfavise pamusoro uye kubvisa kushushikana kwemukati. Kune machira ePTFE anoshandiswa mu-high-frequency copper-clad laminates, yakakosha corona kurapwa inoiswa kuwedzera kushata kwepamusoro.

Lamination Process Pakusefa kwepamusoro-soro, chidimbu chakatetepa chepolytetrafluoroethylene (ePTFE) microporous membrane inonamirwa pamusoro, ichigadzira sefa yepakati nepamusoro-soro yekusefa.

Aokai Nyowani Zvishandiso inoshandisa yakasimba yemhando yekuongorora. Zvigadzirwa zvekupedzisira zvinoedzwa uchishandisa grammage tester, high-voltage tester, uye tensile tester. Zvigadzirwa chete zvine ukomba hwakafanana, zvisina mapini, uye zvinoenderana nezvinodiwa nevoltage resistance zvinoburitswa sezvinhu zvinokwanisa.

Ruzivo rwuri pamusoro rwunopihwa neJiangsu Aokai New Materials Technology Co., Ltd.

Kuti uwane ruzivo rwakadzama, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvemhando yedu yezvigadzirwa - kusanganisira PTFE yakakwirira-tembiricha machira, PTFE yakakwirira-temperature matepi, PTFE yakakwirira-temperature mesh mabhandi, seamless mabhandi efusing presses, single-sided PTFE machira, high-temperature inopikisa, girazi rinopikisa simbi - tapota taura nesu
