Pamberi pePTFE yekuputira, resin impregnation, kana lamination, Fiberglass jira rinofanirwa kunge rakaomeswa. Icho chinangwa chinogona kunge chiri chekungobvisa hunyoro, kana kuti chinogona kusanganisira kupisa machira ekuisa machira (dewaxing), kana kudziya jira kune tembiricha yakagadzikana usati wapfeka. Chinangwa chega chega chinoda tembiricha dzakasiyana uye nguva marongero.
Zvisizvo zvigadziriso zvinogona kutungamirira kuhurombo husina kunaka, kusungirirwa kusina simba, machira ero, kurasikirwa kwesimba - kana kunyange zvimedu zvakakwana.
Aokai PTFE ine ruzivo rwakakura mugirazi fiber kugadzirisa. Gwaro iri rinotsanangura mapoka matatu makuru ekurapa, iwo akanyanya tembiricha mazinga, kutonga nguva, uye matipi anoshanda emhedzisiro inowirirana.

Routine Moisture Removal - The Most Common Process
Iyi ndiyo yakajairwa pre-kuomesa nhanho yejira rakawanda risati raputira kana lamination. Chinangwa ndechekunyatso dehumidification uku uchidzivirira saiziing agents inobata mafiber pamwechete.
1. Kudzora tembiricha
Pamachira emagetsi uye anosimbisa: chengetedza 105°C -120°C.
Pamachira akabatwa ne silane coupling agents : chengetedza tembiricha iri pasi pe110°C kudzivirira kutyora mabhandi ekubatanidza.
Kutsauka kwetembiricha mukati meovheni kunofanirwa kudzorwa mukati me ± 5 ° C kudzivirira kupisa kwenzvimbo.
2. Kudzora nguva (zvichienderana nehuremu hwejira)
Fabric Weight |
Yakakurudzirwa Nguva |
Jira rakatetepa (<100 g/m²) |
10 - 15 maminitsi |
Mucheka wepakati uye unorema (200 – 400 g/m²) |
20 - 30 maminitsi |
Jira rakakora/meti (>600 g/m²) |
1 - 2 maawa kana kupfuura |
Chiyero chekumisa: Huremu hwenguva dzose hunowanikwa kana mutsauko uripo pakati pezviyero zviviri zvakatevedzana uri pasi pe0.1%. Pamachira akakungurutswa, aturike zvisina tsarukano kana shandisa spacer strips panguva yekuomeswa kudzivirira dambudziko rekuoma kwekunze asi mukati mune nyoro.
3. Mapoinzi ekudzora akakosha
Ovheni inofanira kunge yakamanikidza dehumidification . Vhura mavharuvhu emhepo matsva kuti uburitse mweya wakanyorova nenguva.
Usaremedza ovheni; chengetedza kubuda kwemhepo kutenderedza roll yega yega kana sheet.
Dewaxing uye Thermal Kucheneswa - YeUltra-Yakachena Surfaces
Kana jira racho richifanirwa kunge risina zvachose organic saizing agents (semuenzaniso, isati yanyanya kuita resin impregnation yeaerospace kana yepamusoro-tembiricha macomposites), kuchenesa kwemafuta kunodiwa.
1. Kudzora tembiricha
Volatilization & nhanho yekuputa: kutenderedza 300°C. Inoda okisijeni yakakwana uye chiutsi chinopedza simba.
Chinhanho chekupera kwekuneta: zvishoma nezvishoma simudza tembiricha kusvika pa380°C -450°C wobata, kuti unyatso oxidize yasara kabhoni.
Usambofa wakapfuudza 500 ° C - zvikasadaro iyo fiberglass pachayo ichava brittle uye kukuvara.
2. Kudzora nguva
Kune anoramba achipisa anopisa dhizaini, gadzirisa jira rinomhanya kumhanya kuti uve nechokwadi chekuti jira rinogara munzvimbo ine tembiricha yepamusoro kwemaminetsi akati wandei kusvika anopfuura gumi, zvichienderana nehuremu hwejira. Micheka inorema inoda kuratidzwa kwenguva refu.
3. Maitiro ekugamuchira
Kurasika pakudzima (LOI) kuchave kushoma pane 0.1%. Uyu ndiwo mwero wegoridhe.
Muedzo wakareruka wemunda: Batidza kona yejira neretsi. Zvinhu zvakakodzerwa zvinoburitsa utsi hutema kana kunhuhwirira kwakasiyana, nekusara kwemadota kushoma.
Mucheka unokodzera unooneka wakachena kana kuti unochengeta ruvara rwawo rwepakutanga, usina mavara matema kana mitsetse yeyero.
4. Zvinyorwa zvekutevera
Dewaxed fiberglass jira rine yakakwirira pamusoro pekuita . Iendese kune inotevera inregnation process nekukasika, kana sunga uye pasuru nemazvo kudzivirira kutorwazve kwehunyoro uye kusvibiswa.
Preheating Isati Yapfeka - Yekugadzikana Kwemaitiro
Usati waisa PTFE emulsion kana silicone rubber coating, jira racho rinogona kuda preheating zvinyoro kune tembiricha yakagadzikana.
1. Preheating parameters
Set tembiricha: 60°C – 80°C , pamusoro zvishoma pane ambient dova kudzivirira kuomesa pamusoro kuomesa majasi.
Nguva yekugara: kazhinji masekonzi akawanda kusvika kune imwe kana maviri maminetsi kuburikidza nepfupi-renji infrared kana inopisa mhepo oveni - inongokwana kuunza jira kune yakanangana tembiricha.
2. Mirayiridzo yekushanda inoshanda
Tora tembiricha chaiyo yejira seyakajairwa, kwete tembiricha yemhepo yehovhoni. Shandisa infrared thermometers kana inoperekedza tembiricha yekuyeresa michina yekutarisa-nguva chaiyo.
Uniform kuyerera kwemhepo & kutenderera - inopisa mweya convection inosarudza kuomesa kushanda. Uniform mhepo kumhanya inovimbisa kunyangwe tembiricha kugovera pahupamhi hwejira.
Yekutanga sampuli bvunzo: Mabhechi akasiyana anogona kushandisa akasiyana saizi maejenti. Tora masampuli madiki woaomesa pane tembiricha dzakasiyana (105°C, 120°C, 130°C, nezvimwewo). Tarisa kushanduka kwepasi uye kuchinja kwesimba kuti usimbise tembiricha yakachengeteka yebatch yega yega.
Kuchengeta Mushure mekuomesa - Dzivirira Kusvibiswa zvakare
Mucheka wakaomeswa, kunyanya mucheka wakaiswa wakisi, une hygroscopic uye unosvibiswa nyore nyore.
Kana zvisiri zvekushandisa nekukurumidza, chisimbiso mumasaga ealuminium foil ane desiccants.
Zvimwewo: chengetedza muimba yekuomesera ine tembiricha iri pasi pe30°C uye hunyoro huri pasi pe40%.
Yakakurudzirwa hwindo rekushandisa: mukati me4 kusvika 8 maawa mushure mekuomeswa nemhedzisiro yakanaka. Kupfuura izvozvo, omesa zvakare usati washandisa.
Aokai PTFE tip: Kune yakakwirira-yakavimbika application (aerospace composites, yakakwirira-voltage insulation), tinokurudzira kushandisa jira nekukurumidza mushure mekuoma kana mukati maawa maviri.

Aokai PTFE inopa pre-kuomeswa zvirevo kune ese edu fiberglass machira. Nezve maapplication akakosha, tinogona kupa jira rakafanoomeswa uye vacuum-yakavharwa yakagadzirira kushandiswa nekukurumidza. Bata isu kune tsika yekuomesa ma parameter zvichienderana nerudzi rwejira rako uye inotevera maitiro.
Zviri pamusoro apa zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.
Kana iwe uchida kuziva zvakawanda pamusoro pezvakatsanangurwa zvakatsanangurwa, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvechigadzirwa chedu chizere, kusanganisira PTFE machira ekupisa, PTFE high-temperature matepi, PTFE mesh mabhandi, seamless bonding muchina mabhandi, single-sided PTFE jira, yakakwirira-tembiricha isingachinjiki machira egirazi, uye mabhandi anodzivirira girazi.
Isu tinogara tichitsigira huzivi hwehunyanzvi uye kutendeseka, uye takazvipira kukupa iwe-imwe-yekumira mhinduro uye anofunga masevhisi.
