Acrylic vs urethane conformal Coating - Polyurethane Conformal Coating ke Eng?

Liaparo tse tloaelehileng li sebelisoa ho liboto tsa potoloho tse hatisitsoeng ho ntlafatsa ts'epahalo ea sesebelisoa le ho tšoarella. Lisebelisoa tsena tsa polymeric li theha filimi e sireletsang lisebelisoa tsa elektroniki ho tsoa lits'oso tse kang ho bola, metsi le mongobo. Ho na le liphahlo tse fapaneng tsa conformal, har'a tsona epoxy, silicone, acrylic, parylene le polyurethane.

Polyurethane conformal coating ke lera le thata le sireletsang le hananang le ho khoholeha le lihlapolli. Litšobotsi tsa polyurethane li boetse li kenyelletsa

• Ho hanyetsa oli le mongobo
• Flexibility ka hona e lumellana habonolo le libopeho tse fapaneng
• Tekanyo e tsotehang ea mocheso; sehlopha sa F se ikhethileng
• Viscosity e lumella hore bosesaane bo lakatsehang bo fihlellehe
• Tšireletso ea motlakase e tšepahalang; e boloka sekoahelo tekong ea ho palama baesekele

Melemo

Liaparo tsa polyurethane li eketsa bophelo ba sesebelisoa ka ho li eketsa. E netefatsa hore ba ka sebetsa ka mokhoa o ts'eptjoang ho sa tsotelehe maemo.

Ho roala hona ho boetse ho na le matla le ho tiea, ho etsa hore e se ke ea hlola e e-ba le metsoako ea lintho tse phelang le mongobo.

Sekoaelo se thata se hanana le ts'ebetso ea mochini mme se boetse se fokotsa kholo ea litelu tsa thini.

Likopo 

Liaparo tsa polyurethane li loketse ka ho fetisisa bakeng sa lisebelisoa tsa elektroniki tse shebaneng le ho pepeseha ho feteletseng ha lik'hemik'hale. Li ntle haholo ho boloka lijenereithara, li-transformer, li-motor le li-relay, har'a likarolo tse ling, li sirelelitsoe ebile li sirelelitsoe.

Ho roala ho boetse ho tumme libakeng tsa sefofane le likoloi. Ho hanyetsa mocheso oa eona ho etsa hore e sireletse khahlanong le lisebelisoa tsa elektronike sebakeng sa letsoai le lik'hemik'hale.

Ka ho khetha sena ho roala ka mokhoa o hlophisitsoeng mofuta, o na le bonnete ba hore lihlahisoa tsa hau tsa elektroniki li tla sebetsa ka ts'epo le maemong a thata. Polyurethane e na le khanyetso e tlase ea likhohlano le abrasion ha e bapisoa le lisebelisoa tse ling tse lumellanang.

Mokhoa oa ho roala 

Polyurethane conformal coating e fumaneha ka sebopeho sa likarolo tse peli kapa motsoako o le mong. Ho hlatsoa, ​​​​ho fafatsa, 'me u ka sebelisa mekhoa ea ho qoelisa ho kenya lera moo ho hlokahalang. Ka mor'a kopo, filimi e sala ho phekola ka ho feletseng hore mokhoa oa ho roala o felile; sena se nka hoo e ka bang hora ho matsatsi a 'maloa ho phethoa. Le hoja metsoako ea karolo e le 'ngoe e le bonolo ho e sebelisa, e hloka matsatsi pele e phethoa 'me e loketse ho sebelisoa.

Mokhoa oa kopo o ka boela oa khethoa ke mocheso oo mosebetsi o etsoang tlas'a oona. Likokoana-hloko tsa urethane li phekola ka potlako libakeng tseo ho tsona mocheso o leng holimo ka mokhoa o itekanetseng. Ts'ebetso e ka boela ea etsoa ka ho sebelisa mocheso le mahlaseli a UV; ka linako tse ling, ho phekola mongobo ke mokhoa o mong oa ho tšela li-polymers.

Litšitiso 

Polyurethane conformal coating e makatsa mabapi le ho hanyetsa mongobo, abrasion, le mocheso oa mocheso. Leha ho le joalo, e na le bothata ba ho phekola nako e telele. Nako ea ka mor'a phekolo e ka ba nako e telele, 'me e ka qetella e khetholla thepa eo u e thabelang qetellong. Liaparo li boetse li atisa ho fetoha mosehla ha li ntse li tsofala; ha se ntho e amang ho tšepahala ha tsona, empa ha e khahlise ka bokhabane.
