Iyi ngingo irambuye ikoreshwa rya Teflon yubushyuhe bwo hejuru murwego rwingufu zizuba. Porogaramu yibanze muri module lamination: kurekura umwenda ushyizwe hejuru / munsi ya modul ya PV birinda EVA yashonze (140-150 ° C) gukomera kubushyuhe bwa plaque cyangwa plaque, kurinda ibikoresho no kugenzura neza module; imikandara ya laminator yo gukanda / gupakurura byikora; rubber platen ikingira imyenda yongerera ubuzima ubuzima. Kugurisha ingirabuzimafatizo ya selile: umukandara wa convoyeur utwara selile na lente unyuze ahantu hashyushye, hamwe nubuso butari inkoni burwanya flux hamwe nuwagurishije; gushyushya ibishushanyo byo kugurisha aho bakorera. Ubushyuhe bwo hejuru cyane: gupfunyika ibyuma bishyushya, thermocouples, insinga muri laminator no gukiza amashyiga; ibikoresho bitwikiriye amashyanyarazi hamwe ningabo.

Iyi ngingo ikubiyemo intambwe zo kwitegura zisabwa kumyenda ya fiberglass mbere yo gutera intanga ya PTFE. Intambwe ya 1: Gushyushya / gutemba kuri 300-450 ° C kugirango ukureho burundu ibishashara bya paraffine hamwe namavuta biva hejuru ya fibre (ibishashara bya paraffin, ibikomoka kuri krahisi), ubunini busigaye busabwa munsi ya 0.2%, butanga 'umwenda wangiza ubushyuhe. fibre idafite ibirahuri hamwe na PTFE kama; ubucuruzi buraboneka mbere yimiti yatunganijwe irashobora gusimbuka iyi ntambwe ariko igomba kugenzurwa. Intambwe ya 3: Kuma no gushyushya - gukama kuri 80-120 ° C mumasaha 1-2 kugirango ugabanye ubuhehere buri munsi ya 0.1%, birinda ibibyimba / ubusa mugihe cyo gukira.

Iyi ngingo irasuzuma impinduka zuburyo bwimyenda ya PTFE yometseho fiberglass mubidukikije byangiza imiti. Ipitingi ya PTFE irahagaze neza mubitangazamakuru byinshi (harimo na aqua regia, acide yibitseho, ibishishwa kama) - iminyururu ya molekile ntigihinduka. Ibidasanzwe: ibyuma bya alkali bishongeshejwe bivamo fluor itera karubone (umukara / umukara, kuvunika); ibikoresho bikomeye bya fluor (F₂, ClF₃) bimena umugongo wa karubone-karubone; ibishishwa bimwe na bimwe bya Freon bitera kubyimba; ashyushye cyane ya okiside acide itangiza buhoro buhoro amatsinda ya polar hejuru.

Iyi ngingo irambuye ibyerekeranye nimyenda ya PTFE yometseho fiberglass yimyenda ya elegitoroniki ninganda zamashanyarazi. Ibice bitandatu byingenzi: Gukwirakwiza ubushyuhe bwo hejuru no kurinda - moteri ihuza / umwanya / icyiciro cya fonctionnement, insimburangingo ya transformateur, gupfunyika ingofero, ibikoresho byo gushyushya amashanyarazi kwigunga; Gukora umuringa wa laminate no gukora PCB - gusohora imyenda muri lamination ya PCB, prereg na CCL itwara neza; Kugurisha ibikoresho bya elegitoronike - kugurisha masike yo kugurisha / kugurisha urutoki (kurinda urutoki rwa zahabu), imikandara ya convoyeur ya feri, materi yo gukoreramo, ibikoresho byo kurinda imbunda zishyushye; Umuyoboro wa kabili hamwe nu nsinga - icyuma gipima ubushyuhe bwo hejuru gipfunyika kaseti, amaboko yubushyuhe hamwe nigifuniko cyaka umuriro, ubushyuhe bwo kugabanya ubushyuhe bwagutse bwo gutunganya imikandara ya convoyeur; Anti-static hamwe nubwiherero - umukandara wogusukura nu musego wakazi, semiconductor hamwe na Photovoltaque yubushyuhe bwo hejuru.

Iyi ngingo irerekana uburyo bwo gusuzuma uburyo bwo kurwanya no gufata neza ibintu byoroshye bya PTFE yometse kuri fiberglass yimyenda irwanya amavuta n ivumbi. Uburyo bukubiyemo: Guhuza inguni no gupima ingufu zubutaka - inguni yo guhuza amazi mubisanzwe> 110 °, inguni izunguruka 越小越好, ingufu zubutaka nibyiza 18-20 mN / m; Igeragezwa ryibishishwa - 180 ° imbaraga zishishwa hamwe na kaseti isanzwe, byiza <0.1 N / 25 mm; Ikigereranyo cyo kurwanya amavuta yigereranya - uburyo bwo gusiga amavuta gusiga / uburyo busigaye, guhanagura neza guhanagura ukoresheje itandukaniro ryamabara ΔE gupima (ntoya ΔE = gusukura neza), hamwe no gupima amavuta yihuse (kugabanuka kwa wino byerekana kurwanya anti-fouling); Kwipimisha umukungugu - uburyo bwo gutunganya ivumbi hamwe nisesengura ryamashusho, kuvanaho umukungugu wo mu kirere bipima umuvuduko muke uhuha, hamwe nisuzuma rya electrostatike ya adsorption ikoresheje guhangana nubutaka; Isuzuma rirambye - subiramo ibizamini byose nyuma yubushyuhe bwo hejuru (260 ° C / 300 ° C) cyangwa Taber abrasion kugirango urebe neza imikorere yigihe kirekire.

Iyi ngingo ikubiyemo imyenda ya Teflon yubushyuhe bwo hejuru (umwenda wa PTFE ushyizweho na fiberglass) mu kirere. Ahantu h'ingenzi hasabwa: Gukora ibikoresho - gusohora imyenda / firime muburyo bwa autoclave, ibice byo kwigunga, imikandara yubushyuhe bwo hejuru kugirango ikorwe mbere; Moteri hamwe nubushyuhe bwo hejuru bwo kurinda ubushyuhe - ibiringiti byo kubika ubushyuhe, gutwika firewall, guhuza ubushyuhe bworoshye; Gukingira amashanyarazi no kurinda insinga - gupfunyika insinga mu bice bya moteri hamwe n’ibikoresho byo kugwa; Imbere mu ndege no kurinda umuriro - umwenda utwika / inzitizi z'umwotsi zujuje ubuziranenge bwa FST, igitambaro cyo gutwika ubushyuhe / acoustic; Ikoreshwa mu kirere no mu kirere - guteranya ibyiciro byinshi (MLI), guteranya amavuta yo kurwanya imbeho yo gukwirakwiza imirasire y'izuba hamwe na antenna, impuzu zo kugenzura ubushyuhe.

Iyi ngingo isobanura uburyo PTFE itwikiriye imigozi ya fiberglass substrate mu mwenda wo hejuru wa Teflon. Guhuza imiti itaziguye ntibishoboka kubera ingufu za PTFE zidasanzwe. Guhuza bigerwaho binyuze muri: Guhuza imashini (guhuza umubiri) - Emulion ya PTFE yinjira mu cyuho cya fibre hanyuma igafata fibre nyuma yo gucumura; Kwiyubaka kwa Silane - gukora ikiraro cya molekile hagati ya fibre idafite ibirahuri na primer organic; Imiti ya primer yinzibacyuho - ukoresheje PAI, PPS, PES cyangwa PEEK isigarana na micropowder ya PTFE, ikoreshwa nyuma yo guhuza imiti kugirango habeho urwego rukomeye rwinzibacyuho; Amashanyarazi ashyushye ashyushye - FEP cyangwa PFA (gushonga ingingo 260-310 ° C) inkwano yabanje gukora firime ya PTFE kumyenda; Imiterere ya Gradient ikoresheje uburyo bwinshi bwo gutera akabariro hamwe no kuzunguruka - gusibanganya inzira ya mbere hamwe na binder / guhuza ibikoresho byinjira cyane muri fibre, hanyuma bigakurikirwa no guterwa kwa PTFE, bigakora gradient igizwe kuva fiberglass ikagera kuri PTFE.

Iyi ngingo irerekana ibyiza byimyenda yubushyuhe bwa PTFE nkubushyuhe bwo hejuru bwo kuyungurura itangazamakuru. Imbaraga esheshatu zingenzi: Kurwanya ubushyuhe budasanzwe (gukomeza 260 ° C, impinga ~ 300 ° C), kurenga PPS (190 ° C) na aramide (200 ° C); Imiti ikabije ya chimique irwanya aside, alkalis, umusemburo na okiside, irwanya hydrolysis, irusha aramide na P84 muri gaze ya flue yangirika; Imikorere isukuye ivumbi hamwe nimbaraga zidasanzwe zubutaka butuma gukuramo ivumbi byoroshye no kugabanuka k'umuvuduko muke; Uburyo bwiza bwo kuyungurura hamwe nubunini bwa pore 0.1-3μm ifata hejuru ya 99,99% ya PM2.5; Kudashya hamwe na LOI hejuru ya 95%, hamwe na anti-static ihari; Imbaraga zumukanishi zivuye muri fiberglass zishimangira, hamwe nibitangazamakuru byiza bya PTFE bitanga ibintu byoroshye kandi> ubuzima bwimyaka 4. Gereranya neza na PPS, aramid, Nomex, P84 hamwe na fiberglass filter itangazamakuru hejuru yubushyuhe, kurwanya imiti, kurwanya hydrolysis no gukora isuku.

Iyi ngingo itanga ubuyobozi bufatika bwo kwirinda inkari ku mwenda wo hejuru wa PTFE mugihe cyo gucumura. Iminkanyari iterwa ahanini no kugabanuka k'ubushyuhe hamwe no guhangayika bidahuye. Ibisubizo bikubiyemo ibikorwa byuzuye: kugenzura ibikoresho fatizo kugenzura (dewaxing yuzuye / ubushyuhe bwo gukuraho ubushyuhe bwimbere); gutera akabariro no gukama (impuzu nyinshi zoroshye, ubushyuhe bworoheje buringaniye, imashini ikora); kugenzura itanura (1-3% birenze urugero kumafaranga yo kugabanya ubushyuhe bwumuriro, gufunga-gufunga micro-tension kugenzura, guhuza ubushyuhe buringaniye muri ± 5 ° C, buhoro buhoro preheating-sintering-gukonjesha umurongo, itanura ryumuyaga nkibisubizo byiza, ibizunguruka bikwirakwiza); gukonjesha no gushiraho (buhoro buhoro gukonjesha, komeza gukwirakwira kugeza munsi ya 100 ° C, gukonjesha kwuzuye mbere yo kuzunguruka); gukurikirana kumurongo hamwe nubugenzuzi bukomeye bwumucyo hamwe na scan ya infragre.

Iyi ngingo isesengura uburyo kuvura umucanga cyangwa kurangiza kurangiza bigira ingaruka kumiterere yimyenda ya PTFE yubushyuhe bwo hejuru. Impinduka zibaho mubice bitatu: Microscopique morphologie ihinduka kuva mumirorerwamo yoroshye isa nkimiterere ya gully yuzuye hamwe nagaciro ka Ra / Rz byiyongereye cyane, bigashiraho uburyo bwa 3D bwububiko bwa tekinike kugirango buhuze nyuma. Ubusugire bwa coating burahura ningaruka: PTFE igabanuka, ishobora guhura na fiberglass substrate (itera igihombo cyumutungo udafite inkoni, kwinjira mubushuhe, no kugabanya imbaraga za mashini), wongeyeho microcrack hamwe no kubyara imyanda.
