Teko ea Moholi oa Letsoai bakeng sa Likopo tsa Marine: Ho Sireletsa Khahlanong le Libaka tse Hloahloa

Libaka tsa leoatle ha li tšoarele, ho na le moea o tletseng letsoai, mongobo o phahameng, 'me ho lula ho pepeseha lintho tse senyang ho bakang mathata a maholo bakeng sa thepa le liphahlo. Teko ea moholi oa letsoai e fetohile sesebelisoa sa bohlokoa bakeng sa bahlahisi ho netefatsa hore lihlahisoa tsa bona li ka mamella maemo a thata a maemo ana. Sengoliloeng sena, re tla hlahloba bohlokoa ba tlhahlobo ea moholi oa letsoai, re hlahlobe lintlha tsa bohlokoa bakeng sa lits'ebetso tsa leoatle, 'me re totobatse hore na LIB Industry's mochini oa tlhahlobo ea moholi oa letsoai e ka u thusa ho fumana liphetho tse nepahetseng.

Ho Utloisisa Mekhoa ea ho Corrosion Marine

Ho bola ha metsing ke ntho e rarahaneng e tsamaisoang ke lintho tse kang metsi a letsoai, mongobo le mocheso. Li-ion tsa chloride metsing a letsoai li hlasela lisebelisoa ka mokhoa o matla, li potlakisa ho thehoa ha mafome le likoti. Ho feta moo, kutu ea galvanic e etsahala ha litšepe tse sa tšoaneng li kopana ka pel'a electrolyte, e leng se lebisang ho senyeha ha thepa. Mekhoa ena e senya haholo libakeng tsa maoatle, e leng se etsang hore ho be bohlokoa ho etsisa maemo ana nakong ea tlhahlobo ea lihlahisoa ho netefatsa ho tšoarella le ho sebetsa.

Khetho ea Lintho bakeng sa Tikoloho ea Maoatleng

Motheo oa lisebelisoa tsa metsing tse tšoarellang nako e telele o itšetlehile ka ho khetha thepa e nepahetseng. Li-alloys tse hanang ho bola joalo ka tšepe e sa hloekang (316L) le lialloi tsa aluminium-magnesium ke likhetho tse tsebahalang ka lebaka la bokhoni ba tsona ba ho mamella ho bola ho bakoang ke chloride. Liaparo tse sireletsang, tse kenyelletsang epoxy le polyurethane, li matlafatsa nako e telele ka ho etsa thibelo khahlanong le moholi oa letsoai le mongobo. Ho lekola lisebelisoa tsena tlas'a maemo a laoloang a moholi oa letsoai ho netefatsa hore li fihlella maemo a indasteri mme li sebetsa joalo ka ha ho lebelletsoe lits'ebetsong tsa lefats'e la nnete.

Tokiso ea Teko ea Moholi oa Letsoai

Teko ea moholi oa letsoai ha se ts'ebetso e lekanang - e hloka ts'ebetso e hlokolosi ea paramente ho pheta liqholotso tse ikhethang tsa tikoloho e ikhethang ea maoatle. Litlhophiso tsa mochini oa letsoai la letsoai li tlameha ho fetoloa ho laola likarolo tsa bohlokoa:

- Letsoai la letsoai: Tharollo ea teko hangata e na le 5% sodium chloride, empa liphetoho li ka etsisa maemo a mabifi.

- Mocheso: Libaka tsa leoatle lia fapana, kahoo ho laola mocheso oa kamore ea liteko (mohlala, maemo a 35 ° C) ho netefatsa papiso e nepahetseng.

- Nako ea ho pepeseha: Teko ea nako e telele (ho tloha ho lihora tse 24 ho isa ho libeke tse 'maloa) e lekola ho tšoarella ha nako e telele.

Mohlala, likarolo tsa sekepe tse pepeselitsoeng ho phatloha ha metsi a leoatle li ka hloka litekanyetso tse fapaneng tsa tlhahlobo ho feta likarolo tsa turbine ea moea tse kenngoeng ke letsoai le moeeng. Ka ho lokisa mefuta ena hantle, bahlahisi ba ka bolela esale pele hantle hore na lihlahisoa tsa bona li tla sebetsa joang ha nako e ntse e ea libakeng tsa leoatle.

Ho lekanya Ts'ebetso ea Coating

Liaparo ke mokhoa oa bohlokoa oa tšireletso khahlanong le ho bola ha leoatle, empa ha se liphahlo tsohle tse sebetsang ka ho lekana. Mochini oa tlhahlobo ea moholi oa letsoai o bapala karolo ea bohlokoa ho lekola matšoao a bohlokoa a ts'ebetso joalo ka ho hanyetsa letsoai, ho khomarela le ho tšoarella ka kakaretso.

- Blisting: Lipululana tse nyane tse hlahang ka tlas'a seaparo li bontša ho kenella ha mongobo le ho hloleha ho ka bang teng.

- Ho rusa: Tekanyo ea ho bopeha ha mafome holim'a mafome a koahetsoeng e lekantsoe ho lekola khanyetso.

- Tahlehelo ea ho khomarela: Liteko li senola hore na koae e khomarela joang substrate ha nako e ntse e feta.

Mohlala, seaparo sa epoxy sa boemo ba metsing se ka bonts'a ho phatloha ho fokolang le ho khomarela ka matla tlas'a tlhahlobo ea moholi oa letsoai, e leng se etsang hore e be se loketseng meaho e ka tlas'a metsi. Ka lehlakoreng le leng, liphahlo tse sa atleheng litekong tsena li nkoa li sa tšoanelehe bakeng sa maemo a thata a leoatle. Litlhaloso tsena li matlafatsa bahlahisi ho khetha le ho hloekisa liphahlo bakeng sa tšireletso e phahameng.

LIB Salt Fog Test Machine

Mochini oa tlhahlobo ea moholi oa letsoai oa LIB Industry ke tharollo e tsoetseng pele e etselitsoeng ho fihlela litlhoko tse matla tsa lits'ebetso tsa metsing. Melemo ea mantlha e kenyelletsa:

- Taolo e Nepahetseng: Mocheso o tsoetseng pele, mongobo, le litsamaiso tsa taolo ea sefaha sa letsoai li netefatsa papiso e nepahetseng ea maemo a nnete a lefats'e.

- Ho tšoarella le ho ts'epahala: E hahiloe ka thepa e sa jeng, likamore tsa LIB li entsoe ho fana ka ts'ebetso e ts'oanang ka lilemo tsa ts'ebeliso.

- Moralo o ka tloahelehang: Litharollo tse hlophisitsoeng li lumella basebelisi ho fetola maemo ho ikatisa maemo a itseng a leoatle.

- Ho Ikamahanya le Maemo: Likamore tsa LIB li kopana le litekanyetso tsa machaba tsa tlhahlobo, ho kenyeletsoa ASTM B117 le ISO 9227, ho netefatsa liphetho tse tšepahalang le tse tšepahalang.

Teko ea moholi oa letsoai ke ea bohlokoa bakeng sa bahlahisi ba sebetsang liindastering tsa metsing. Ka ho utloisisa mekhoa ea kutu, ho khetha lisebelisoa tse nepahetseng, ho ntlafatsa litekanyetso tsa tlhahlobo, le ho lekola ts'ebetso ea ho roala, likhoebo li ka hlahisa lihlahisoa tse tšepahalang, tsa boleng bo holimo. Lik'hamphani tsa LIB mochini oa tlhahlobo ea moholi oa letsoai e fana ka tharollo e phethahetseng bakeng sa ho fihlela lipheo tsena. Ho fumana lintlha tse ling kapa ho bua ka litlhoko tsa hau tsa tlhahlobo, ikopanye le rona ho ellen@lib-industry.com.
