Ni ukubera iki Hydrophobi Yabanje Gushushanya Urupapuro rwa aluminiyumu Guhinduka itegeko kuri Offshore Wind Turbine Nacelle Cladding?

Umuyaga wo mu nyanja ukorera mu bihe bikabije by’ikirere: guhora uhura n’amazi meza yo mu nyanja ya NaCl aerosol), imivurungano ikaze y’umuyaga, imishwarara myinshi ya UV, hamwe n’ibara ry’ibihe. Mugihe ibyubatswe byo mumazi bigenda mumazi maremare hamwe na turbine zifite ingufu nyinshi (12 MW - 20 MW +), nacelle - amazu yububiko bwa garebox, generator, na transformateur - bisaba ubwubatsi bwuzuye bwubatswe.

Imyambarire isanzwe yo mu nyanja irwana no guhumeka ikirere cyo mu nyanja hamwe no kwiyubakira urubura, biganisha ku busumbane bw’uburemere bw’imashini, kwihutisha imyobo yaho, ndetse no kumanura igihe. Hydrophobic yabanje gushushanya irangi rya aluminiyumu ikomatanya aluminiyumu yo mu rwego rwa marine (5000/6000 ikurikirana) hamwe na sisitemu ya nano yakozwe na superhydrophobic fluoropolymer (inguni θ> 150 °) . Sisitemu yibikoresho irinda ibitonyanga byamazi gukomera, kumena umunyu mugihe cyimvura, kandi bikagabanya urubura rwinshi, bikigaragaza nkigipimo cyingenzi cyo kwambika nacelle yo hanze.

Ubukanishi bwububiko bwa Alloy Substrate

Ikibaho cya Nacelle gisaba imbaraga zingana-nuburemere kugirango uhangane ningufu zipakurura mugihe hagabanijwe misa yo hejuru:

5052 50. /

Kuzigama kwa misa yubatswe: Gusimbuza GRP iremereye (Glass Reinforced Plastique) ibishishwa byinshi cyangwa ibyuma byo mu nyanja byo mu nyanja bidafite ibyuma, bigabanya uburemere bwamazu ya nacelle kugera kuri 30% - 40%.

Ingufu zo hejuru & Fluoropolymer Hydrophobic Technology

Ikoti ya superhydrophobique yishingikiriza kuri micro-nano ebyiri zubuso bwahinduwe hamwe nubutaka-buke-ingufu za fluoro-monomers:

Ultra-High Water Contact Angle (θ> 150 °): Ibitonyanga bya spray yo mu nyanja bigumana geometrike ya serefegitura hanyuma bikamanuka ku mpande ntoya (<5 °).

Kwemeza Tekinike & Ibipimo ngenderwaho

Imikorere ya matrix iri hepfo yerekana ibipimo byo gupima laboratoire ya hydrophobique yabanje gushushanya irangi rya aluminium nacelle:

Ibyingenzi Byumwuga Mubyubuhanga bwo mu nyanja

Ibibazo

Q1: Kuki aluminium hydrophobique ikunzwe kuruta GRP (fiberglass) kuri nacelles yo hanze?

Igisubizo: Hydrophobique yabanje gusiga irangi aluminiyumu itanga imbaraga zingaruka nyinshi, kudakongoka, kugabanuka kurwego rwo hejuru, kongera gukoreshwa neza, kandi ikuraho ibyago byo kwangirika kwa resin cyangwa osmose yibibyimba mugihe cyamazi yumunyu uhoraho.

Q2: Nigute hejuru ya hydrophobi irinda kwirundanya umunyu kuri nacelles?

Igisubizo: Kubera ko ibitonyanga byamazi bidashobora gukwirakwira hejuru yubuso buhanitse (θ> 150 °), spray yo mu nyanja yo mu kirere ikora imirongo ifatanye ako kanya, igatoragura uduce duto twumunyu mbere yuko yuma mumatongo akomeye.

Q3: Ese igipfunyika cya hydrophobique gitakaza ibintu byangiza amazi mugihe gikabije cya UV?

Igisubizo: Hydrophobic yo murwego rwohejuru ikoresha FEVE fluoropolymer cyangwa silicone yahinduwe na polyurethane matrix irwanya isenyuka rya UV, ikomeza impande zose zoguhuza amazi mugihe cyigihe kinini cyubuzima bukora.

Q4: Ese hydrophobique yabanje gushushanya irangi rya aluminiyumu irashobora kugororwa igakorwa muburyo bwa nacelle?

Igisubizo: Yego. Sisitemu yo gutwikisha yakozwe muburyo bworoshye (1T - 2T igipimo cyo kugonda), ituma feri ikanda-feri, gukora ibizunguruka, hamwe no gutondekanya ikibaho nta gucamo mikorobe cyangwa gutakaza hydrophobicite.

Q5: Nigute ibi bikoresho bigabanya ibikorwa byo hanze no kubungabunga (O&M)?

Igisubizo: Mu gukumira umunyu hamwe no kwegeranya urubura rwinshi, ibikoresho bikuraho ibikenerwa byo gusukura intoki zo ku nkombe kandi bikagabanya kubungabunga nacelle bijyanye no kwangirika, bizigama kajugujugu nini n’ibikoresho byo gushyigikira ubwato.

Umwanzuro

Hydrophobic yabanje gusiga irangi aluminium shee t ihitamo uburyo bwiza bwo guhitamo ibikoresho byo mu nyanja ya turbine nacelles yo mu nyanja, bitanga uburyo bwizewe bwo kurwanya ibishushanyo, kwisukura, ndetse no kurwanya ruswa mu bihe bikabije byo mu nyanja.

Kugirango hamenyekane neza ibikoresho byatoranijwe kumushinga wumuyaga wo hanze:        

Kugaragaza Core ya Marine Aluminium ( 5052-H32 cyangwa 5083-H116): Menya neza ko guhitamo substrate bitanga imbaraga zihagije zihagije hamwe no kurwanya ruswa yo mu nyanja.

Mandate Yemejwe na Hydrophobi Parameter (Twandikire Angle}> 150 °): Saba kugenzura ko ubuso bugumana inguni nkeya zidafite ingufu na nyuma ya UV hamwe no gupima abrasion.

Kugenzura Ibipimo byumunyu & Ice Shear Ibipimo: Shimangira byibuze amasaha 4.000 ASTM
