Ese FEVE Yashizwemo 5083 Igiceri cya Aluminiyumu Ihangane namasaha 5.000+ yumunyu wumunyu winyanja utarinze gushiramo?

Imbaraga zituruka hanze, inyubako zubatswe ku nkombe, ibikorwa remezo byicyambu, hamwe n’ibikoresho bifasha mu mazi bikorera muri bimwe mu bidukikije byangiza isi. Ubushuhe bwinshi bwa chloride ion yo mu kirere ( $ inyandiko {Cl} ^ - $ ), guhora uhura na ultraviolet, hamwe nubushuhe bugereranije bwihuta kwangirika hagati yimibumbe no guhuza ibice byuma bitarinzwe.

FEVE (Fluoroethylene Vinyl Ether) yashizwemo ibishishwa bya aluminiyumu 5083 ihuza aluminiyumu yo mu rwego rwo hejuru yo mu nyanja ya aluminiyumu hamwe na chimie yo hejuru ya fluoropolymer. Iyo bitunganijwe hifashishijwe uburyo bwo kubanza kubanza kubuvura no kubitondekanya neza, iyi sisitemu yibikoresho ishobora kwihanganira amasaha 5.000+ yo kwipimisha umunyu uhoraho (ASTM B117 / ISO 9227) hamwe na zeru zometseho, guhuha, cyangwa gusiba.

Imiterere yuburyo bwa 5083 Marine-Grade Substrate

Bitandukanye na aluminiyumu isanzwe 3003 cyangwa 1100 urukurikirane rwubatswe, 5083 aluminiyumu itanga ubushobozi bwo kwikorera imitwaro myinshi hamwe ninyanja yo hasi yinyanja:

Imbaraga Zitanga Imbaraga & Umuyaga-Umuvuduko Kurwanya: Kugera ku mbaraga zitanga ingufu ziri hejuru ya MPa 215, birinda ihinduka ryimiterere ya elastike munsi yumuyaga wumuyaga winyanja hamwe n’umuvuduko ukabije w’ikirere.

Exfoliation Resistance (H116 / H321 Tempers): Igenzurwa rya Thermomechanicicale rihagarika imvura ikomeza kugabanuka kumupaka wa β -pase (Mg₂Al₃), ikarinda gucika hagati yimiterere yabantu igihe kirekire.

Inzira ya Polymer

FEVE fluoropolymer iragaragaza imiterere ihindagurika ya molekile ya fluoro-monomers na vinyl ethers ikora:

Ingufu nyinshi za Fluorine Bond: Imiti ihamye ya CF (485 kJ / mol) irinda gufotora imishwarara ya ultraviolet, ikomeza kurabagirana no gutuza amabara.

Isocyanate Hydroxyl Kwambukiranya: Bitandukanye nubushuhe bwa termoplastique PVDF bushingiye kumubiri, FEVE ikora umuyoboro wuzuye, wibice bitatu bya polyurethane uhagarika ikwirakwizwa ryamazi yumunyu hamwe niyimuka rya chloride ion.

Kwemeza Tekinike & Ibipimo ngenderwaho

Imikorere ya matrix ikurikira irerekana ibipimo ngenderwaho byingenzi byo gupima laboratoire ya FEVE ikozweho 5083:

Ibyingenzi byingenzi byumwuga muri Marine & Architectural Engineering

Ibibazo

Ikibazo1: Kuki 5083 ivanze ihitamo 3003 cyangwa 5052 kugirango ikoreshwe mu nyanja?

Igisubizo: 5083 ibinyobwa birimo magnesium nyinshi ( 4.0% - 4.9% ), bitanga umusaruro mwinshi mwinshi hamwe no kurwanya imbere kwangirika kwinyanja ugereranije nintego rusange 3003 cyangwa 5052 ibivanze.

Q2: Nigute sisitemu ya FEVE resin igera kumasaha 5.000+ yo kurwanya umunyu utarinze gutera?

Igisubizo: FEVE ikora ubucucike, thermosetting imiyoboro itatu-ya polymer binyuze muri covalent polyurethane ihuza. Iyi barrière yimiti idahumanya irinda ubushuhe hamwe na ioni ya chloride itera ( Cl ⁻) guhura na aluminium substrate.

Igisubizo: Yego. Imyenda ya FEVE ikize itanga impagarike nziza yuburemere bwubuso ( 2H - 3H ) hamwe no guhindagurika kuramba, bigatuma panne ishobora kunyura 1T - 2T  no gukora imashini ikora idafite mikorobe.

Q4: Ni irihe tandukaniro nyamukuru ryibikorwa hagati ya FEVE na PVDF mubidukikije byo mu nyanja?

.Igisubizo ​​

Q5: Nigute impande zaciwe zigomba gukoreshwa mugihe cyo gushiraho umurima?

Igisubizo: Mugihe 5083 alloy isanzwe ihindagurika, uburyo bwiza bwo gushiraho igihe kirekire cyo mu nyanja burimo gukoresha umuyaga ukiza FEVE cyangwa epoxy edge kashe ya kashe kumpande zogosha kugirango ukureho ingaruka ziterwa na firime.

Umwanzuro

FEVE isize 5083 ibishishwa bya aluminiyumu bitanga igisubizo kirambye kidasanzwe, cyoroshye, kandi kirwanya ruswa gishobora gutsinda amasaha 5.000+ yo kwipimisha umunyu uhoraho utarinze gutobora cyangwa kunanirwa na firime.

Gutezimbere ibikoresho byatoranijwe kumushinga winyanja ninyanja:

Kugaragaza Marine-Grade Alloy & Temper (5083-H116 / H321): Menya neza ko insimburangingo yibanze ikoresha ubushyuhe bwa H116 cyangwa H321 kugirango wirinde kwangirika kw’imiterere n’imyunyu ngugu.

Gutegeka Ubunini Buke Buke (40μm DFT): Shimangira sisitemu yimyenda ibiri igizwe na primer yubatswe cyane (≥ 12μm) hamwe na kote ya FEVE (≥ 28μm) kugirango uburinganire bwuzuye bwuzuye.

Kugenzura ibipimo ngenderwaho byo gupima: Saba raporo ya laboratoire yemewe yemeza amasaha 5000 ASTM B117 kwihanganira gutera umunyu hamwe na ASTM G154 QUV ikirere.
