PVDF FEVE

Mugushushanya inyubako ndende, inkuta zumwenda, hamwe n amabahasha yinganda, kwerekana neza neza inyuma ni ngombwa. Imyubakire ya aluminiyumu igezweho ihora ikorerwa n’ibidukikije bikabije: imirasire y’izuba ultraviolet (UV), gusiganwa ku magare y’umuriro, ubushuhe, n’imyuka ihumanya ikirere. Mu myaka ibarirwa muri za mirongo, fotone ya UV isenya imiyoboro ngengabuzima mu marangi asanzwe, igatera kurigata, isuri, no gushira.

Kugirango wirinde kwangirika kwububiko, ibisobanuro byubwubatsi akenshi bisaba fluoropolymer irangiza yujuje AAMA 2605 . Tekinoroji ebyiri zibanze zujuje aya mahame akomeye ni PVDF (Polyvinylidene Difluoride) na FEVE (Fluoroethylene Vinyl Ether) . Mugihe byombi bikoresha chimie ya karubone-fluor, imiterere ya molekuline, ubushobozi bwubwiza, nimyitwarire yimikorere iratandukanye cyane. Isesengura rya tekiniki rigereranya PVDF na FEVE impuzu kugirango igufashe guhitamo neza kurangiza UV irwanya umushinga wawe.

Ibikorwa-Byinshi Byubatswe Fluoropolymers

Gusobanukirwa uburyo ibifuniko bya fluoropolymer bihanganira igihe kirekire hanze bisaba gusuzuma chimie yabyo.

Uruhare rwa Carbone-Fluorine (CF) Imirasire y'izuba

Ihungabana rya fluoropolymer ituruka kumurongo wa Carbone-Fluorine (CF) . Ingufu za CF zingana na 485 kJ / mol , zirenga ingufu za fotone yumurasire wizuba ultraviolet (UV -A na UV-B, hafi 300 - 410 kJ / mol). Kubera ko imirasire ya UV idafite imbaraga zo guca imigozi ya CF, umugongo wa polymer urwanya gusenyuka, ukarinda gucika, guhiga, no gusaza imburagihe.

Gusobanura PVDF na FEVE Resin Architecture

• PVDF PVDF Ibipimo ngenderwaho bisanzwe bisaba kuvanga 70% PVDF resin na 30% acrylic resin kugirango bigerweho neza, byoroshye, hamwe no guhuza pigment.

• FEVE FEVE Ibice bya fluoroethylene bitanga imbaraga za UV kandi biramba, mugihe ibice bya vinyl ether bigira uruhare mu gukorera mu mucyo, kurabagirana, gukomera, gukomera kwa resin, hamwe nubushobozi bwo guhuza.

Imikorere & Ibisobanuro Matrix: PVDF v. FEVE

Ubucuruzi bwubucuruzi-off & Imikoreshereze Bikwiye

Guhitamo hagati ya PVDF na FEVE akenshi biza mubisabwa guhimbwa, ubwiza bwifuzwa, hamwe nibihe byurubuga.

Ibibazo

Q1: Ese FEVE iruta UV irwanya PVDF ?

Igisubizo: Ibikoresho byombi bitanga imbaraga zidasanzwe za UV zujuje cyangwa zirenga AAMA 2605 . PVDF FEVE

Q2: Ni ukubera iki FEVE ikundwa kubwuburebure-bwuzuye bwububiko bwububiko bwuzuye?

Igisubizo: FEVE ikoresha 100% ya thermosetting fluoropolymer imiterere ikomeza kuba murwego rwo hejuru. PVDF bisaba inyongeramusaruro ya acrylic igabanya igisenge cyayo hejuru ya 20 - 35; kugerageza guhatira PVDF murwego rwo hejuru rwurumuri rugabanya ikirere cyacyo.

Q3: Ni izihe ngaruka zo gukoresha abaguzi batabigenewe kubikoresho bya aluminiyumu yoroheje?

Igisubizo: Abatanga ibicuruzwa batabigenzuye barashobora gukoresha umubyimba udahuye, ubushyuhe budakira, cyangwa pigment yo hasi. Izi nenge zirashobora gutera kurigata, ibara ritaringaniye kugabanuka ( ΔE > 5.0), cyangwa gutwikisha ibishishwa mumyaka mike gusa yo hanze.

Q4: Ese FEVE na PVDF -ibishishwa bya aluminiyumu bishobora gushyirwaho nyuma bikagoramye?

Igisubizo: Yego, ariko 70% PVDF itanga ihinduka ryiza (0T - 1T yunamye) kubera imiterere ya termoplastique, bigatuma irushaho kunama. FEVE ​

Q5: Nigute Changzhou Dingang Metal Material Co., Ltd. (Ubushinwa) yemeza ko umubyimba uhoraho?

Igisubizo: Dingang Metal Material Co., Ltd. ikoresha ibyuma byerekana ibyuma byerekana ibyuma byerekana ubugari hamwe na roller ifunze. Ibi bikoresho bikomeza kwihanganira uburebure bwimbitse mubugari bwuzuye n'uburebure bwa coil ya aluminium.

Q6: Ni ukubera iki kugabanuka nyuma yo kuzunguruka ari ingenzi kuri 1050 H24?

Igisubizo: Ibisigazwa bisiga amavuta bisigaye ku cyuma birashobora gukora nka bariyeri, bikarinda gusiga irangi, ibifatika, cyangwa firime zirinda guhuza neza. Kwangirika neza bituma ubuso bufite isuku n'imbaraga zo hejuru ( ≥ 38 mN / m ), bikarinda gusiga irangi no kunanirwa.

Umwanzuro

Kugera kumwirondoro uhoraho muri Gukora neza neza bisaba gusobanukirwa neza ubushyuhe bwibintu hamwe nimbibi zo guhindura ibintu. Mugufatanya numushinga wagenzuwe utanga kwihanganira igipimo gihoraho, imiterere yubukanishi buringaniye, hamwe nubutaka busukuye, uremeza ko umusaruro wawe ukomeza kutarangwamo imiraba, gucamo ibice, hamwe nimashini ihenze kumasaha.
