Imyenda irwanya static ya PTFE igerwaho hakoreshejwe uburyo bubiri bwingenzi: gutwikira doping (kuvanga ibyuzuza ibintu nka karuboni yumukara muri emulioni ya PTFE, gukora umuyoboro wa percolation kuri concentration ikomeye) hamwe no kuboha insimburangingo (gushyiramo fibre ikora mumyenda ya fiberglass). Kurwanya ubuso bigenzurwa kuri 10⁵ - 10⁹ Ω. Ihame: shiraho inzira iyobora itwara ibicuruzwa bihagaze ako kanya, birinda kwirundanya kwangiza. Impamvu ni itegeko kubikorwa byiza.

Inkoko muri emulioni ya PTFE ikora imirimo ine yingenzi: guhagarika ihagarikwa (birinda gutuza uduce duto twa PTFE), imyitwarire yo kunanura imisatsi (ubukonje bwinshi kuruhuka, hasi munsi yimyigaragambyo yo gutwikira byoroshye), kugenzura ubujyakuzimu bwimbitse (igenga imizigo yipakira kumyenda ya fiberglass), hamwe nuburinganire bwa firime (birinda gucika mugihe cyo kumisha). Icyangombwa gikenewe: umubyimba ugomba kubora burundu kuri ~ 380 ° C yubushyuhe, hasigara ivu rya zeru kugirango habeho isuku no gutwika amashanyarazi.

Imyenda yubushyuhe bwo hejuru ya PTFE (fibre yububiko bwa PTFE) itanga imiti idasanzwe yo kurwanya imiti, hamwe na acide yibanze (harimo na aqua regia), alkalis ikomeye (mubushyuhe bwicyumba), ibishishwa kama, hamwe na okiside. Ibidasanzwe: ibyuma bya alkali byashongeshejwe hamwe nubushyuhe bwo hejuru bwa halogene yibasira PTFE. Kwangirika kwifata byerekana fiberglass kuri acide hydrofluoric na alkalis zishyushye cyane. Ubushyuhe buri hejuru ya 260 ° C bugabanya kurwanya. Kubintu byinshi byimiti, imyenda ya PTFE ikomeza guhagarara neza kandi yizewe.

Ubushuhe bugari bwa PTFE kaseti isaba silicone PSA ikomeza gufatana kuva kuri 70 ° C kugeza 260 ° C. Ibintu by'ingenzi byashushanyijeho: primer-anchored layer layer (irinda gusiba), microstructure yo mu kirwa cyo mu nyanja (MQ resin birwa + polysiloxane ikomeza icyiciro), guhuza buhoro buhoro (urwego rwimbere rwimbere rwo guhangana n’ibikururuka, urwego ruciriritse rwo hasi rwihuta), hamwe nuzuza ubushyuhe (okiside ya cerium). Igice cya fenyl cyahinduwe na siloxane irwanya ubushyuhe buke bwo korohereza ibintu, bigatuma ihinduka ryoroshye -100 ° C.

Aokai PTFE yerekanye ibicuruzwa byuzuye muri APFE Shanghai 2026 (Booth 6T602, Hall 6). Ibicuruzwa byerekanwe birimo kaseti ya PTFE yongerewe imbaraga, firime nziza ya PTFE, amanota arwanya static, hamwe n’umukandara woherejwe n'ubushyuhe bwo hejuru - bikubiyemo gutunganya ibiryo, PV lamination, bateri ya lithium, ibikoresho bya elegitoroniki, hamwe no gupakira. Imurikagurisha rizatangira ku ya 26 Kamena.Ibicuruzwa byose bishyigikira ibisobanuro byihariye.

Imyenda ikomeye ya PTFE yubushyuhe bwo hejuru ni igizwe na fiberglass yo hejuru cyane-hamwe na PTFE. Ibyingenzi byingenzi bikwirakwizwa mu nganda (guteka ibiryo, kumisha imyenda, gutwara PCB), kurinda gusudira (gutwikira ubushyuhe, gufunga ingabo), kumanura no gushyiramo imashini zishyushye (gushushanya reberi, PV lamination), kubika amashanyarazi (moteri ya moteri, gupfunyika insinga), ibyubatswe byubatswe (ibisenge bya stade, ubuzima bwa tekinike) porogaramu (gukata laser, icapiro rya 3D).

Kuma nintambwe ikomeye mubikorwa bya PTFE yubushyuhe bwo hejuru. Inenge zisanzwe zirimo: guturika (gukama vuba cyane, uruhu rwo hejuru), kwimuka kwimuka (ibice byimuka hejuru, guhuza imbere imbere), pinholes / ibisebe (umwuka wafashwe cyangwa umwuka), ibibara byera hamwe na chalking (kwimuka kwa surfactant cyangwa fusion ituzuye), umuhondo / kokiya (gushyuha cyane) ariko imbere itose (uruhu rwo gufata imitego yubushyuhe), nimpande zimbitse (ingaruka ya kawa-impeta). Ibisubizo bikubiyemo imyirondoro yumye, guhumeka neza, hamwe no kwitegura.

Gukata kumpera yimiterere ya PTFE yubushyuhe bwo hejuru cyane bigira ingaruka zifatika zifatika hamwe no kuzamura impande mugihe cyo kubisaba. Kunyerera nabi (blade idahwitse, inguni idakwiye) itera kole ya kole, ikanagabanya impande zombi zifata neza, kandi ikagaragaza ibibyimba bya fiberglass - biganisha ku gucika intege, guhuza imbaraga, no guterura munsi yubushyuhe cyangwa impagarara. Isura yanyuma idasanzwe (wavy, isohoka) itera gukwirakwiza umuvuduko muke, gutwara ibinyabiziga bifata mugihe cyo kubika. Isura nziza yanyuma isa neza, ihindagurika, kandi nta byangiritse - ikora nk'ikidodo gifunga ibifatika kandi kigahuza impande zose.

PTFE emulsiyasi yimyenda ya fiberglass isaba abafasha batandukanye kugirango bagere kumyenda imwe, gufatana gukomeye, hamwe nubuso butagira inenge. Ibintu byingenzi byongeweho harimo: ibikoresho byo guhanagura (kugabanya ubukana bwubutaka, kunoza kwinjira), kubyimbye (kugenzura ububobere nuburemere bwa coating), kugenzura pH (guhagarika emulioni kuri pH 9-10), ibikoresho byo guhuza silane (kongera imbaraga kumirahuri), imfashanyo zikora firime (PFA / FEP yo gucumura), kuzuza imikorere (kwangirika kwangiza) Guhitamo biterwa na substrate nibisabwa.

Mugihe cya kaseti ya PTFE, igipimo cya volatilisation yumuti wa silicone yumuvuduko ukabije ni ikintu gikomeye. Byihuta cyane → uruhu rwo hejuru, kuringaniza nabi, pinholes (umutego wafashwe), hamwe na crater (kondegene cyangwa iterwa n'umwanda). Biratinda cyane → kugabanuka, impande zibyimbye, no gutonyanga hejuru-imbaraga-PTFE. Ingamba nziza: gahoro gahoro guhindagurika kugirango uringanize kandi uhunge, hanyuma byihuta byumye kugirango bibe. Koresha imvange ivanze (toluene / xylene + yumisha vuba) hamwe nubushyuhe bwa feri ya gradient (hasi → hagati → hejuru).
