PTFE ntabwo isanzwe ifatanye na fibre y'ibirahure. Hatabayeho kuvura neza, PTFE itwikiriye Imyenda ya PTFE yubushyuhe bwo hejuru byo kurangiza - kuvura imiti ikoreshwa kumyenda ya fiberglass mbere yo gutwikira.
Izi mikorere - cyane cyane imiti ihuza organosilane - ikora nkibiraro bya molekile, ihuza imiti ya fibre yikirahure kidasanzwe na PTFE kama. Guhitamo abakozi, kwibanda kwayo, hamwe nuburyo bwo gukiza bigena muburyo bukomeye imbaraga zishishwa, kurwanya ubushyuhe, ubuzima bworoshye, nibikorwa bya dielectric.
Aokai PTFE yateje imbere isura ya chimie mumyaka mirongo yakozwe. Aka gatabo gasobanura ibyiciro byingenzi byabakozi, ingaruka zabyo kumitungo yingenzi, nimpamvu kuvura neza bidashobora kuganirwaho kumyenda myiza ya PTFE.
Ibyiciro byingenzi byubuso burangiza abakozi
Mbere yo gutwikira PTFE, umwenda wa fiberglass muri rusange ukurwaho ibishashara no gukora hejuru. Imiti yo kuvura ishyirwa mubice byimiti nkibi bikurikira:
Icyiciro
Ibicuruzwa bisanzwe
Ibiranga & Porogaramu
Umukozi wo guhuza Organosilane (Byakoreshejwe Byinshi)
Amino silane (KH-550 / A-1100); Epoxy silane (KH-560 / A-187)
Ikoreshwa binyuze muri Si-OH hamwe nitsinda rya hydroxyl hejuru yikirahure cya fibre; Amatsinda akora yibikorwa bigize imiti ihuza umubiri cyangwa ibiraro bifatika → ibiraro bya molekile, byongera cyane gufatira hamwe
Umukozi wo guhuza Titanate
Monoalkoxy & chelate titanates
Kurwanya ubushyuhe buhebuje bujyanye na sisitemu ya fluoropolymer; itezimbere PTFE itose kuri fiberglass, irwanya iyangirika ryimiterere yubushyuhe bwinshi
Fluorined Coupling Agent
Perfluoroalkyl triethoxysilane
Ultra-hasi yingufu zubutaka, hejuru ya PTFE ihuza; urunigi rwa parfluorocarubone kuzamura kuzamura adhesion, hydrophobicity, imikorere ya antifouling
Chromium Complex Kurangiza Umukozi
Volan (methacryloyl chromium chloride)
Uburyo bwa kera bwo kuvura; icyiciro bitewe nibidukikije & recycling impungenge nubwo ingaruka zifatika zidasanzwe
Inorganic Nano Sol
Silica sol, alumina sol
Kurema nano-nini ya topografiya ya topografiya hejuru ya fibre yububiko bwa mashini; mubisanzwe byongewe hamwe nibikoresho byo guhuza
Polymeric Primer
Uburemere-buke bwa PTFE / FEP / PFA ikwirakwizwa, resin primer ivanze na agent ihuza
Ifite ultra-thin inzibacyuho ya fluoropolymer kuri fiberglass kugirango byoroherezwe guhuza amakoti; bigabanya cyane ibyago byo gusiba
Aokai PTFE ikoresha uruvange rwihariye rwa epoxy silane hamwe na fluorine ihuza ibikoresho kugirango tubone ubushyuhe bwo hejuru bwa PTFE. Iyi formulaire irwanya serivisi 260 ° C ikomeza nta kwangirika kwimiterere - byemejwe namasaha 3.000 yo gupima ubushyuhe.
Ingaruka Kubintu Byiza bya PTFE Imyenda Yubushyuhe Bwinshi
Gukora nkibikoresho bitandukanya hagati yikirahure cyibirahure na fluoroplastique, urwego rwo kuvura no gutunganya byiganje mubikorwa byuzuye birangiye.
1. Gukomera kwa Adhesion & Peel Kuramba
Ubwiza bwo kuvura
Imbaraga
Uburyo bwo kunanirwa
Kutavurwa / gufatwa nabi
<2 N / cm
Gupfundikanya ibibyimba, gusibanganya nyuma yo kuzunguruka / kuzinga cyangwa ubushyuhe bwo hejuru; ubuzima bucye
Umukozi uhuza neza
4-8 + N / cm
Guhuza imiti + kwangirika kumubiri; gutwikira birwanya gukuramo munsi guhindagurika no guhindagurika
Ingaruka zikomeye: Imbaraga zishishwa nikintu gikomeye cyubuzima bwa flex umunaniro no kurwanya delamination.
2. Kurwanya Ubushyuhe & Ubushyuhe Bwinshi
Ibikoresho bifata ubushyuhe bwinshi (birimo benzene cyangwa imiterere ya heterocyclic, urugero, epoxy & acyloxy silanes) bihanganira 260 ° C hamwe nimpinga zihita> 300 ° C - bihuye na serivisi ya PTFE.
Imyunyu ngugu isanzwe yangirika cyane kubushyuhe bwo hejuru ids ubusa busa, ibara ry'umuhondo, ibara ryuzuye.
Porogaramu isaba: Kubushyuhe bwo hejuru bwo hejuru, menya neza ko umukozi urangiza ubwayo ahamye neza, ntabwo ari PTFE gusa.
Guhindura silane imwe byongera PTFE emulsion ikwirakwira no guhanagura hejuru ya fibre → ikomeza guhuza hamwe na pinhole nkeya na microcracks → ingenzi kumeneka ya voltage nubushobozi bwo kubika.
Imiti ivura Hygroscopique cyangwa ion yanduye itera igihombo cya dielectric. Silane-isukuye cyane yemewe kumyenda yo mu rwego rwo hejuru ya PTFE kugirango igabanye kwivanga kwanduye.
4. Kurwanya imiti & Barrière
Ubwoko bw'abakozi
Ingaruka
Umukozi wo guhuza fluor
Indangabintu ya hydrophobique & oleophobic → ibuza capillary kwinjira mubushuhe hamwe nimiti yangirika → itezimbere cyane gusaza-ubushyuhe, acide & alkali
Inorganic nano sol
Inzitizi yuzuye irinda fibre yibirahuri kuribwa na aside hydrofluoric hamwe nibitangazamakuru byangirika
5. Guhinduka no guhindagurika
Ikintu
Ingaruka
Kurenza urugero cyangwa gukomera-matsinda-akungahaye kubakozi
Komera imyenda, ubuze ibikorwa byo kudoda no gupfunyika
Gukora hamwe na birebire byoroshye-urunigi
Igumana pliability idatanze imikorere yo guhuza
Icyitonderwa gifatika: Ingano yumukozi urangije gukoreshwa igomba kuba iringanijwe neza - bike cyane bitera kwifata nabi, cyane bigabanya guhinduka.
Incamake - Impamvu abakozi barangiza Surface ari ngombwa
Umutungo
Ingaruka zo Kuvura neza
Ingaruka z'abakene / Nta muti
Kuramo imbaraga
4-8 + N / cm
<2 N / cm → gusiba, kubyimba
Kurwanya ubushyuhe
Ihagaze kuri 260 ° C +
Ubusa hagati, umuhondo, kuzunguruka hejuru ya 200 ° C.
Imikorere ya dielectric
Gukomeza gutwikira, pinhole nkeya
Igihombo kinini cya dielectric, ibyago byo gusenyuka
Kurwanya imiti
Ihagarika ubuhehere / imiti ya capillary
Ikirahure cya fibre yibirahure, kunanirwa imburagihe
Guhinduka
Igumana pliability iyo itezimbere
Umwenda ukomeye, biragoye gupfunyika
Ibyingenzi byingenzi: Ibikoresho byo kurangiza ni tekinoroji yibanze yo gukora imyenda yubushyuhe bwo hejuru ya PTFE. Yiganjemo imiti ihuza ibinyabuzima, iyi miti yubaka molekile ihuza imiterere-ngenga-ngenga kugirango ikemure PTFE idahwitse ya fiberglass. Bagena muburyo bukomeye imbaraga zishishwa, igihe cyigihe cyo kubaho, kurwanya ubushyuhe, kubika amashanyarazi, hamwe nubusembure bwimiti.
Muncamake , igikoresho cyo kurangiza cyashyizwe kumyenda ya fiberglass mbere yo gutwikira PTFE ntabwo ari ikintu gito - ni umusingi wubuziranenge bwubushyuhe bwo hejuru bwa PTFE. Ibikoresho byo guhuza organosilane (amino, epoxy, fluorine) birema ibiraro byingenzi bya molekile hagati ya fibre yikirahure na PTFE, bikongerera imbaraga ibishishwa kuva kuri <2 N / cm kugeza kuri 4-8 + N / cm. Kuvura neza kandi byongera imbaraga zo guhangana nubushyuhe (260 ° C +), guhuza ibicuruzwa, gukora dielectric, no kurwanya imiti.
Mugihe uhisemo umwenda wa PTFE kugirango usabe porogaramu, baza kubijyanye na chimie yo hejuru - bigira ingaruka mubuzima bwa serivisi no kwizerwa. Irinde insimburangingo zitavuwe cyangwa zidakorewe nabi, zizasenyuka munsi yubushyuhe nubukanishi.
Ukeneye imyenda yohejuru ya PTFE yubushyuhe bwo hejuru hamwe neza neza? Aokai PTFE ikoresha uburyo bwo guhuza ibikorwa byiterambere kugirango bishoboke kandi biramba. Twandikire hamwe nibisabwa.
Ibirimo Bitangwa na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.
Kubisobanuro birambuye, ubuyobozi bukoreshwa, hamwe nibisubizo byabigenewe byuzuye mubicuruzwa byuzuye: PTFE mwenda muremure wa temp, icyuma gifata PTFE, umukandara wa meshi wa PTFE, umukandara wa fuser udafite ikidodo, umwenda umwe wa PTFE wuzuye umwenda, umukandara wa convoyeur utarwanya ubushyuhe hamwe nigitambara cyo hejuru cya fiberglass , nyamuneka twandikire:
Dushimangiye ubunyangamugayo nubunyangamugayo, dutanga impande zose igisubizo kimwe cya tekiniki hamwe na serivisi nziza kubakiriya.
