Jiangsu Aokai New Materials, inyanzvi inogadzira machira ePTFE akakwira-tembiricha, anopa sumo izere. Maitiro ekupfekedza jira refiberglass rine PTFE dispersion ndiyo yakakosha tekinoroji yekupfeka uye sinter polytetrafluoroethylene pane fiberglass substrate, kugadzira zvinhu zvakaumbwa zvine tembiricha inopikisa, kuvharwa kwemagetsi uye kusaita tsvimbo. Zvigadzirwa zvakadaro zvinoshandiswa zvakanyanya mu-high-frequency copper-clad laminates, yakakwirira-tembiricha isina-tsvimbo conveyor mabhandi, architectural membrane zvinhu uye mamwe minda.
Iyo yakakwana yekutanga maitiro ine matanho manomwe akakosha seanotevera:
1. Fiberglass Fabric Pretreatment (Dewaxing / Desizing)
Iri ndiro danho rinonyanya kukosha rekutanga kurapwa. Mushonga wekugadzira machira (kunyanya parafini wax, starch derivatives) wakaputirwa pamafilamende efiberglass panguva yekuruka; kubviswa kusina kukwana kuchakanganisa zvakanyanya kubatana kwepakati pakati pePTFE negirazi fibers.
· Nzira huru yekurapa: Iro jira rinoramba richipfuura nemuchoto chekupisa kwekushisa kwe 350 ~ 400 ° C, yakazara oxidizing uye kuora zvose organic saizing agents.
· Mabatirwo anotevera: Mucheka wakaiswa wakisi unotonhodzerwa pasi, dzimwe nguva wosukurudzwa nemvura yakachena kana zvinonyungudutsa kemikari kuti ubvise madota asara, wozoomeswa kuwana jira jena risina chinhu rakachena ragadzirira kuiswa.
· Raw material: Yakaiswa PTFE kuparadzirwa ine mwero yakasimba yemukati inosvika 60%.
· Kusanganisa maitiro: Diluesa kuparadzirwa kwemasheya nemvura yakashongedzwa kusvika kune yakatarwa (40% -55%) zvichibva pane inodiwa resin kurodha uye impregnation viscosity. Yakakodzera surfactant inowedzerwa kuwedzera wetting performance pane fiberglass; thickener inogona kubatanidzwa kugadzirisa viscosity kana zvichidikanwa.
3. Kuiswa pamuviri
Chinangwa chepakati ndechekupinda kwakazara kwePTFE emulsion mufiber bundles uye interstices yejira rakarukwa.
1. Dip-Squeeze Method (Yakanyanya kugamuchirwa): Iyo jira inotungamirwa kuburikidza nekunyudza rollers kuti inyure zvizere mu emulsion tank, yobva yapfuura nepaviri yekusvina rollers. Coating uremu inodzorwa nekugadzirisa roller nip pressure kuti ibudise yakawandisa emulsion uye kugovera resin zvakafanana.
2. Chiremba Blade Coating: Emulsion inopararira pamusoro pejira rejira kuburikidza nesimbi blade, yakakodzera kune yakakwira-viscosity dispersions.
4. Kuomesa
Jira rakaiswa pamuviri rinopinda muhovhoni yekuomesa yakadzikama inoshanda pa100 ~ 150°C.
· Chinangwa: Nyura zvinyoronyoro mvura uye mafirita chidimbu, uchigadzira firimu risingatapi rakaoma rezvikamu zvePTFE pane faibha.
· Tembiricha yekudzora chiziviso: Kunyanya kupisa tembiricha kuchakurumidza kuumba firimu repamusoro, richiteya hunyoro hwemukati hunofefetedza kugadzira mapini uye mablister.
5. Sintering (Thermal Curing)
Mucheka wakaomeswa unobva wapinzwa muchoto chekupisa chepamusoro chekupisa kupisa pa 360 ~ 390 ° C (kusvika ku400 ° C kune mamwe mamakisi).
· Mechanism: PTFE ndeye thermoplastic polymer. Pane tembiricha iri kure pamusoro pekunyungudika kwayo (327 ° C), PTFE zvimedu zvinonyunguduka, kuyerera uye kuenzana kuti zvigadzire firimu rinoenderera, richiwana mechanical interlocking uye kunamatira nefiberglass nzvimbo.
· Danho rechikamu: Iyo sintering zone yakakamurwa kuita yekudziya rampu, inogara-tembiricha sintering uye kutonhora zvikamu kuvimbisa yakazara particle fusion pasina kushatisa kupisa.
6. Multi-Cycle Impregnation & Sintering
Iyo imwe chete impregnation-sintering cycle inongogadzira iyo yakanyanyisa-yakatetepa coating inokonzeresa maburi epini. Kuti usvike kune chinangwa chekuputira ukobvu uye resin yemukati (semuenzaniso, 45% -65% resin kurodha kune yakakwira-frequency copper-clad laminate substrates), iyo yakazara kutevedzana kwe impregnation → kuomesa → sintering inodzokororwa 2 kusvika 4 nguva kana kupfuura. Kutenderera kwega kwega kunowedzera kuzadza mafiber gap uye kunowedzera ukobvu hwekufukidzira, pakupedzisira kugadzira pinhole-isina dense composite sheet.
7. Mushure-Kurapwa & Winding
1. Kugadziriswa kwepamusoro: Mushure mekupedzisira sintering pass, corona kurapwa kana kemikari sodium-naphthalene etching inogona kuiswa kunatsiridza kunamatira kwepamusoro pasina kukuvadza substrate, kufambisa inotevera mhangura yekupfeka kana yechipiri coating.
2. Kucheka kweEdge & kumonereka: Mipendero yemucheka inochekwa yakatwasuka, ipapo jira rakapedzwa rinokuvadzwa zvakanaka nemuchina wekutora.
3. Kuongorora kwemhando: Kuyedzwa kwakazara kwezvinhu zvakapedzwa zvinosanganisira hwaro huremu, ukobvu, kusimba kwesimba, kusimba kwepeel, dielectric inogara uye hurema hwekuona.
Core Process Control Points
Iwo akakosha maparamendi anotonga akapedzwa kunaka kwechigadzirwa ndeaya: yakazara deizing / dewaxing, yakazara emulsion wetting, zvishoma nezvishoma-yakadzika-tembiricha kuomeswa, chaiyo sintering tembiricha yekumisikidza, uye inowirirana coating density mushure mekutenderera kwakawanda.
Izvo zviri pamusoro pehunyanzvi zvemukati zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.
Kana iwe uchida kuwana tsanangudzo dzakadzama, mamiriro ekushandiswa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere chepodfolio chinosanganisira PTFE yakakwirira-tembiricha jira, PTFE yakakwirira-temperature adhesive tepi, PTFE yakakwirira-temperature mesh bhandi, seamless kupisa kudzvanya bhandi, single-sided PTFE jira, yakakwirira-tembiricha inodzivirira girasi uye inodzivirira kupisa girazi, tapota taura nesu pazasi-inodzivirira girazi.
