Ho sebelisoa ha polyurethane conformal coating
Polyurethane conformal coating ke mofuta oa thepa eo hangata e sebelisoang indastering ea elektroniki. Ke filimi e tšesaane, e tenyetsehang e ka sebelisoang ho liboto tsa potoloho tse hatisitsoeng le likarolo tse ling tsa elektronike ho li sireletsa tikolohong. Liaparo tse tloaelehileng li ka sebelisoa ka spray, dip, kapa brush. Polyurethane conformal coating ke khetho e ntle bakeng sa lits'ebetso moo ho hanyetsanang le mocheso oa mocheso ho hlokahalang.
Liboto tsa potoloho tse hatisitsoeng ke mofuta o atileng haholo oa karolo ea elektroniki e koahetsoeng ka mokhoa o hlophisitsoeng. The conformal barbotage e sireletsa boto ho tloha mongobo, lerōle, le litšila tse ling. E boetse e fana ka thibelo khahlanong le li-shorts tsa motlakase.
Liaparo tse tloaelehileng li boetse li sebelisoa likarolong tse ling tsa elektronike, tse kang lihokelo le li-switches. Li ka boela tsa sebelisoa ka libeteri le lisele tsa mafura.
Liaparo tse entsoeng ka polyurethane li ka sebelisoa ka ho fafatsa, ho qoelisoa kapa borashe. Ho roala ka spray ke mokhoa o tloaelehileng haholo. Thepa ea ho roala e kopantsoe le solvent ebe e fafatsoa holim'a motsoako. The solvent e fetoha mouoane, e siea filimi e tšesaane ea conformal holim'a metsi.
Dip coating ke mokhoa o mong o tsebahalang oa ho sebelisa li-polyurethane conformal coatings. Karolo e qoelisoa ka har'a sekoti sa thepa ea ho roala ebe e ntšoa. Thepa e feteletseng e tlosoa, 'me karolo e lumelloa ho omella.
Ho roala brush ke khetho ea ho sebelisa polyurethane litlolo tse hlophisitsoeng. Thepa ea ho roala e phunyeletsoa holim'a karolo e ka holimo. Hangata mokhoa ona o sebelisoa bakeng sa ho lokisa liphahlo tse senyehileng tsa conformal.
Polyurethane conformal coatings indastering ea likoloi
Liaparo tsa polyurethane conformal li sebelisoa indastering ea likoloi ho sireletsa likarolo tsa elektroniki ho tloha mongobo, lerōleng le litšila tse ling tsa tikoloho. Hangata li sebelisoa ho liboto tsa potoloho le likarolo tse ling tsa elektronike tse hlokolosi pele li kopana ka koloing. Liaparo tsa polyurethane conformal li fana ka tšireletso e eketsehileng khahlanong le kutu le lifupi tsa motlakase 'me li ka lelefatsa bophelo ba likarolo tsa elektronike ka ho li sireletsa linthong.
Liaparo tsa polyurethane conformal li fumaneha ka mebala e fapaneng, botenya, le nako e telele ho fihlela litlhoko tse ikhethileng tsa indasteri ea likoloi.
