Semugadziri anotungamira we Jiangsu Aokai New Materials Technology Co., Ltd. inounza kwauri ruzivo rwehunyanzvi. Nepo jira refiberglass richiramba riri iro rinonyanya kushandiswa pakuisa pamuviri wePTFE , mamwe akawanda ma substrates aripo - rimwe nerimwe richipa zvivakwa zvakasiyana kune chaiyo-yepamusoro-kuita maapplication.
Pazasi isu tinoongorora 7 mamwe ma substrates, maitiro avo maitiro, zvakanakira, uye zvinogumira.
Aramid Fiber (semuenzaniso, Kevlar®)
Maitiro: Yakarukwa kuita machira kana tubular zvimiro, zvobva zvapinzwa nePTFE.
Zvakanakira: Ultra-yakakwirira tensile simba, yakanakisa kupfeka kuramba, murazvo retardancy, uye makemikari inertness. Inosanganisa simba repamusoro nekuchinjika kwemafuta-isina lubrication.
Zvishandiso: High-pressure valve packings, aerospace components, bulletproof inodzivirira zvinhu.
Zvisingakwanisi: Kudhura kwakanyanya kudarika fiberglass; murombo UV kuramba.
Carbon Fiber
Maitiro: Kazhinji inogadzirwa muakarukwa kurongedza, wozoiswa pamuviri nePTFE.
Zvakanakira: Simba rakakwirira, yakakwira modulus, yepamusoro yekupisa conductivity (inodzivirira kupisa kuunganidza), yakaderera thermal yekuwedzera coefficient.
Zvishandiso: Mamiriro ezvinhu akanyanya - kupisa kwakanyanya, kudzvanywa kwakanyanya, kukurumidza kukurumidza; semiconductor kugadzira michina.
Zvisingakwanisi: Mari yekugadzira yakakwirira; yakawedzera friction coefficient (yakagadziridzwa mushure mePTFE coating); inherently conductive - inoda kurapwa kwekudzivirira mune mamwe mamiriro.
PBI (Polybenzimidazole) Fiber
Maitiro: Yakarukwa kuita tubular zvimiro, zvozoiswa nePTFE emulsion uye sintered.
Zvakanakira: Yakatanhamara yakakwirira-tembiricha kuramba - inochengetedza michina zvivakwa uye kupfeka kuramba pamusoro pe400 ° C.
Zvishandiso: Yakasimba-yepamusoro-tembiricha chengetedzo uye chisimbiso mune aerospace uye echiuto maindasitiri.
Zvisingakwanisi: Kunyanya kudhura; kugadzikana kushoma munzvimbo dzakakwirira-kupisa aerobic; chete yakakodzera kune niche minda.
PBI fiber inoratidza kugadzikana kwekupisa kwekupisa - mukati mekuyera kwayo tembiricha renji, iyo fiber yekutanga modulus inoramba iripo. Munzvimbo inert gasi kana vacuum, kunyangwe mushure memaawa 300 pa350 ° C, hapana kuchembera kwakakosha kunoitika. Apo PBI fiber tubes inopinzwa nePTFE emulsion kuburikidza ne-multi-stage process (kunyura, kuomeswa, kubika, uye kunyunguduka), iyo inoguma anti-wear liner inogona kumira kuenderera kwekushanda kwekushisa kwe290 ° C, kubuda pakarepo kusvika ku500 ° C, nekurasikirwa kwehuremu pasi pe5% pa 315 ° C uchiramba uchiramba uchipfeka. Zvekushandisa zvakaita semasimbi einjini dzendege, zvinhu zvechinyakare zvakaita seEPDM, nitrile rabha, jira-rakasimbiswa silicone rabha, uye yakajairwa PTFE haigone kuita izvi zvinodiwa - PBI/PTFE macomposites anogadzirisa zvese zvekupikiswa nekupisa uye nyaya dzekupfeka, zvichiwedzera zvakanyanya mikana yekushandisa.
Maitiro: PTFE dispersion fluid inopinda nesimbi pores kuburikidza nevacuum impregnation, inoteverwa nepamusoro-tembiricha sintering.
Zvakanakira: Inosanganisa kusimba kwesimbi uye kugadzikana kwedimensional nePTFE's self-lubricity uye corrosion resistance.
Zvishandiso: Mabhengi ekuzvinyudza, mhete dzepiston, njanji dzekutungamira, uye zvimwe zvikamu zvemakanika.
Zvinogumira: Zvakaomarara zvinodiwa pasimbi porosity uye pore saizi kugovera kuve nechokwadi chakakodzera PTFE impregnation.
Porous Graphite
Maitiro: PTFE inozadza mukati graphite pores kuburikidza akazvitsaurira impregnation uye plasticizing kurapwa.
Zvakanakira: Mafomu isingapindiki graphite ine yakanakisa corrosion resistance - inoshandiswa mumakemikari ekutsinhanisa kupisa uye reactor liner. Zvakare anoshandiswa zvakanyanya mune yakakwira-tembiricha yekuisa chisimbiso gaskets.
Zvishandiso: Chemical processing equipment, high-temperature seals.
Zvisingakwanisi: Graphite ine brittle; Kudzora kwakasimba kunodiwa kuti uve nechokwadi chekumirirwa yunifomu uye kusungirirwa kwakasimba kwemukati.
Asbestos (Legacy Substrate)
Maitiro: Traditional impregnation substrate; asbestos faibha dzakapinzwa nePTFE kuti dziruke zvikamu zvine simba zvekuisa chisimbiso.
Zvakanakira: Yakambogamuchirwa zvakanyanya munzvimbo dzakasiyana dzekuisa chisimbiso.
Zvinogumira: Yakarongedzerwa secarcinogen - yakabviswa kana kurambidzwa zvakanyanya munzvimbo zhinji, zvishoma nezvishoma inotsiviwa nearamid fibers.
Ceramic Fillers
Maitiro: Yakasanganiswa zvizere ne PTFE emulsion kuti iite composite slurry, yozoshandiswa kupfekedza reinforcing substrates semucheka wefiberglass.
Zvakanakira: Kunyatso gadzirisa dielectric nguva dzose uye dielectric kurasikirwa - kwakakosha kune yakakwira-frequency, yakakwirira-kumhanya yemhangura clad laminates.
Zvishandiso: Zvemagetsi - PCB substrates ye5G uye yakakwirira-frequency kutaurirana.
Zvisingakwanisi: Kudzora kwemaitiro akaoma; inoda yunifomu filler dispersion muPTFE.
Mhedziso - Sarudza iyo Yakakodzera Substrate kune Zvaunoda
Nepo jira refiberglass richiramba riri bhiza rekugadzira machira akavharwa nePTFE , dzimwe nzira dzakaita searamid, kabhoni faibha, porous metal, uye graphite zvinopa mabhenefiti akasarudzika emamiriro akanyanya - kubva kumhepo kusvika kune semiconductor kugadzira.
Pakusarudza substrate yePTFE impregnation , funga:
Kushanda tembiricha uye zvakatipoteredza
Mechanical simba uye kupfeka zvinodiwa
Magetsi conductivity kana insulation zvinodiwa
Mutengo uye kuwanikwa
Semugadziri akavimbika wePTFE akavharidzirwa machira , Aokai inopa mhinduro dzakagadziridzwa mukati mePTFE mabhandi ekutakurisa, PTFE mesh mabhandi, PTFE adhesive tepi, PTFE film tepi, uye PTFE fiberglass tepi..
Izvo zviri pamusoro apa zvinopihwa neJiangsu Aokai New Materials Technology Co., Ltd.
Kuti uwane tsanangudzo yakadzama, mhinduro dzemashandisirwo, uye masevhisi akajairwa ezvigadzirwa zvedu zvakazara zvinosanganisira PTFE tembiricha yakakwira tepi, PTFE mesh bhandi, bhandi remushini wakashongedzwa, rimwe divi rePTFE jira, tembiricha inodzivirira bhandi rekutakura uye jira refiberglass , ndapota inzwa wakasununguka kutibata nesu:
Isu tinoomerera kune hunyanzvi uye kuvimbika, takazvipira kupa imwe-stop yakavimbika mhinduro uye masevhisi ane hanya kune vese vatengi pasi rese.
