Iyi ngingo ikubiyemo uburyo bwo guhuza umuvuduko wumurongo wumurongo hamwe nuburebure bwa furu kugirango hamenyekane ko imiti ya organosilicone igera kurwego rwo gukiza kurwego rwo hejuru rwa PTFE. Ihame ryibanze rihuye: igihe cyose cyo gutura t_total = uburebure bwa furu burebure L ÷ umurongo umuvuduko v ugomba kuba munsi yigihe gito gisabwa cyo gukira. Shakisha imiti ikiza ukoresheje DSC cyangwa ibizamini byo gukiza byerekana 'ubushyuhe - igihe gito cyo gukiza ' umubano. Icyitegererezo cyo gukiza kimwe: kugabanya ifuru muri zone, kubara ti = Li / v na tcure (Ti), menya ∑ (ti / tcure (Ti)) ≥1. Uburyo bwo kubara: shiraho ubushyuhe bwuburebure bwa Li n'ubushyuhe Ti; shiraho umurongo wihuta v, ubare buri zone igihe cyo gutura nigipimo cyintererano; gusubiramo kugeza byose hamwe ≥1 (margin umutekano 1.1-1.2 bisabwa).

Iyi ngingo ikubiyemo ingaruka ziterwa na gamma-ray kumirasire ya PTFE nimiterere. Imiterere yimiti ihinduka: imirasire ya gamma isenya iminyururu nyamukuru ya CC nu munyururu wa CF (G-agaciro 3.0-3.5), itera urunigi runini no kugabanuka kwa molekile bikabije; muri ogisijeni, radicals yubusa ikora peroxy radicals itangiza acyl fluoride na acide karubasi ya acide (hydrolyzing to HF). Imiterere ihindagurika: ihinduka rya kristu irazamuka muburyo bwambere (ikinini gito, iminyururu migufi yongeye gutondekanya) hanyuma igwa (ikinini kinini, inenge ihungabanya kristu); kristu ya lamellar igabanyijemo uduce duto twa kristalite hamwe no kubura intera ndende. Kwangirika k'umutungo: kurambura kuruhuka bigabanuka kuva 0.1 kGy mu kirere, gutakaza> 90% kuri ~ 1kGy - ibikoresho biba bikomeye kandi byoroshye; gushonga bigabanuka kuva kuri 327 ° C kugeza munsi ya 310 ° C; amatsinda ya polar azamura gato dielectric ihoraho / gutakaza; isura ihinduka kuva cyera kugeza imvi / umukara hamwe no gutakaza gloss.

Iyi ngingo ikubiyemo ibyiza byo gukoresha imyenda ya Teflon yubushyuhe bwo hejuru muri batiri ya lithium yumye. Ikoreshwa nkimikandara ya convoyeur cyangwa ifuru, gukemura ibibazo bitatu byingenzi: gufatira hamwe, kwangirika, no gushushanya electrode. Ibice bine byibyiza: Ubwiza bwa electrode numusaruro - imitungo irwanya inkoni irinda PVDF guhuza bifasha gukuramo byoroshye; imiyoboro imwe yubushyuhe kuri 100-140 ° C irinda gucika / gutwika; ubuso bunoze bukuraho ibishushanyo no kumena ifu; Kuramba no gukora neza - kurwanya imiti irwanya NMP hamwe na myuka ya electrolyte idafite kubyimba / gusaza; imbaraga zingana kandi zihamye ziva muri fiberglass substrate kugirango ihagarare neza; gusukura byoroshye hamwe nibisigara bike ugereranije nimikandara ya mesh.

Iyi ngingo ikubiyemo ibintu byo gusibanganya imyenda ya Teflon yo hejuru. Gusiba bivuga gutandukana no gutobora hagati yubuso bwa PTFE nigitambara cyimbere cya fiberglass cyangwa hagati yububiko bwinshi. Kugaragara kugaragara: guhuha / kubyimba (kuzamura ibibyimba byuzuye) nk'ibimenyetso byambere; interlayer peeling hamwe nigitambaro cyakuweho byoroshye mumpapuro zerekana fiberglass yera; cyera cyera gikurikirwa no guhindagurika nyuma yubushyuhe / guterana. Impamvu nyamukuru: Kwangirika kwubushyuhe bwumuriro - gutandukanya coefficient zo kwagura ubushyuhe hagati ya PTFE na fiberglass bitera guhangayika imbere, ubushyuhe bwihuse / gukonjesha bitera gutandukana; Umusemburo mwiza wumusaruro - kuvura fibre idahagije, kuvura nabi kwa PTFE, gucumura bidahagije bitera guhuza imikoranire idahwitse.

Iyi ngingo irasuzuma impinduka zimiterere muri PTFE yubushyuhe bwo hejuru mugihe cyo gusaza. Ibice bine: microstructure ya PTFE - gukwirakwiza urunigi rwa molekile hamwe na okiside (gushinga amatsinda ya karubone / carboxyl), ihinduka rya kristu (kuzamuka hakiri kare noneho gusenyuka), micro-crack na pinhole, ifu yubutaka; Ikirahuri cya fibre substrate hamwe ninteruro - ubunini / guhuza ibice byangirika bitera igihombo cyo guhuza, gutandukana hagati no gutandukana (guhuha, ahantu hera), isuri ya fibre fibre isuri no kuyitobora, imvura ya alkali ya oxyde itera kwangirika kwangirika; Imiterere ya Macroscopique nuburyo bugaragara - guhindura ibara (umweru → beige → umukara → umukara), kugabanuka kwimiterere no kugabanuka, hejuru yubutaka no gutakaza gloss, ifu iyo ikoraho, gutakaza burundu guhinduka. Ibyingenzi byo gusaza: inzira igenda itera 'gutwika igabanuka failure gutsindwa kwimbere → substrate degradation. '

Iyi ngingo isobanura uburyo bwo guhinduka mumbaraga zifatika za PTFE ubushyuhe bwo hejuru bwa kaseti ifata nyuma yubusaza bukabije. Inzira y'ibyiciro bitatu: Nyuma yo gukira izamuka ryicyiciro (ubushyuhe bwo hejuru bwo hejuru yubushyuhe bwo hejuru kuri 200-260 ° C, amatsinda asigaye akomeza guhuzagurika, ubumwe bwiyongera cyane); Icyiciro gihwanye neza (guhuza inzira yegereje kurangira, guhuriza hamwe biguma bihamye mugihe kirekire); Gutesha agaciro no kugabanuka (igihe kirenze / ubushyuhe butera urunigi nyamukuru kwangirika, guhuzagurika kugabanuka, gufatira byoroshye no guhinduka). Hasesenguwe imizi itera kunanirwa gufatana hamwe (gutanyagura imbere gusiga ibisigara) no gusohoka (gutembera gukonje kuva kumpande kubera kugabanuka kwa modulus).

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 irerekana uburyo bwo kunoza imirwanyasuri hamwe nigihe kirekire cyo gufata neza Teflon ifite ubushyuhe bwinshi. Ingamba zirimo: Molecular net topologiya optimizasiyo - igipimo kinini cya MQ silicone resin / gum igereranyo (1.2: 1-22: 1) ikora ibyiciro bikomeye bigoye; kwinjiza amatsinda ya fenyl (20-30 mol%) abuza urunigi; uburemere bwa molekuline bugenzurwa kuri 5.000-15,000 g / mol; Gradient modulus multilayer adhesive structure - primer-anchoring layer (1-3μm) hamwe na silane ihuza silane, urwego rwo hejuru-modulus cohesive layer (30-50μm) nka skeleton idashobora kwangirika, skelet ikora ya viscoelastic (3-8μm) kugirango itose hejuru; Nanofillers - silika yumye (10-25 wt%) hamwe no guhindura isura itera guhuza umubiri guhinduka.

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.
