Tšebeliso ea Epoxy Topcoat ho Industrial Anticorrosion

Epoxy topcoat ke ea likarolo tse peli tsa epoxy resin topcoat tse fapaneng, tse nang le thepa e khethehileng ea ho hanyetsa, ho hanyetsa tšusumetso, ho hanyetsa metsi ka mokhoa o babatsehang, ho hanyetsa ha letsoai le ho hanyetsa mocheso (150 ° C e tsoelang pele). E loketse likamore tse ka tlase tsa ntlo ntle le khanya ea letsatsi Anticorrosive le topcoat e khabisitsoeng tikolohong.

E sebelisoa hammoho le epoxy primer, filimi e thata ebile ha e sebetse, e phela nako e telele, 'me e na le ts'ebetso e tsotehang ea ho hanyetsa metsi, ho hanyetsa oli le lik'hemik'hale. Leha ho le joalo, ka lebaka la lithibelo tsa mocheso nakong ea kaho, ho hahoa ha mocheso o tlaase ha ho khonehe. Joaloka pente e nang le likarolo tse peli, ho thata ho e sebelisa. Epoxy topcoat e na le khanyetso e mpe ea ka ntle ea leholimo, e tla ba phofo le ho lahleheloa ke khanya, e ama mokhabiso, empa e na le phello e fokolang ts'ebetsong ea ts'ireletso.

Liaparo tse ngata tse teteaneng tsa epoxy li 'nile tsa sebelisoa e le liaparo tsa ka holimo tse sa hlokeng mokhabiso o motle ka hare ho likarolo tsa mohaho kapa tikolohong ea ka tlung. Hobane libaka tsena li ke ke tsa pepeseha mahlaseli a letsatsi a ultraviolet, ha ho hlokahale hore u tšoenyehe hore filimi ea ho roala e tla ba phofo.

Epoxy topcoat e loketse ts'ireletso ea lijana, mechini le lisebelisoa tsa indasteri, lihlahisoa tsa mochini le tsa motlakase, meaho ea tšepe, lisebelisoa tsa lik'hemik'hale, marokho, sethala sa offshore, likepe tsa likepe, tšireletso ea holim'a konkreite, libaka tse lebopong la leoatle le lisebelisoa tse metsi le tsa tropike le tse ling tsa tšepe le tse seng. -mabaka a tshepe. Topcoat e khabisitsoeng.

Seaparo sa holimo ke seaparo sa ho qetela sa setšoantšo, 'me ke lera la ho qetela le sebelisoang mokhabisong oa lerako la mohaho. Phello e akaretsang ka mor'a mokhabiso e bonahala ka lera lena. Ka hona, ho na le litlhoko tse phahameng bakeng sa lisebelisoa tse sebelisoang, eseng feela ho ba le chroma e ntle le khanya, empa hape le ho ba le khanyetso e ntle ea tšilafalo, ho hanyetsa botsofali, ho hanyetsa mongobo, ho hanyetsa hlobo, le tikoloho e sa silafatsang, e sireletsehileng le e seng chefo , Che. kotsi ea mollo, kaho e bonolo, ho omisoa ka potlako ha filimi ea ho roala, khanya e ntle le ho boloka mebala, ho phunyeletsa hantle joalo-joalo. Ka mesebetsi ea mokhabiso le ts'ireletso, joalo ka 'mala, gloss, sebopeho, joalo-joalo, e boetse e hloka ho hanana le maemo a thata.

Resin e ka theha mefuta e meraro e hasantsoeng ea metsi ka mekhoa e fapaneng e thehiloeng metsing: ① e qhibilihang ka metsing; ② mofuta o hasantsoeng oa micelle; ③ emulsion. Epoxy resin ka boeona ke thermoplastic linear structure. Ka mor'a ho futhumatsa, boemo bo tiileng bo fetoha boemo ba metsi, 'me viscosity e phahameng e fetoha viscosity e tlaase. Ke feela ha e sebelisoa hammoho le moemeli ea phekolang moo e leng ea bohlokoa bo sebetsang. Hardener). Ka hona, tsamaiso ea epoxy e nang le metsi e lokela ho ba le metsi a epoxy resin le epoxy e phekolang ka metsi. Ka mokhoa o ts'oanang, li ka etsa mefuta e meraro ea ho hasana ha metsi ka litsela tse fapaneng tsa metsi. Ka hona, tsamaiso ea epoxy e nang le metsi e na le mefuta e mengata ea khetho (ka khopolo-taba e na le mefuta e 9 ea motsoako oa morphological), empa hape e eketsa bothata ba khetho. Ka nako e ts'oanang, ts'ebetsong ea sebele ea kopo, ka ho eketsa palo e kholo ea li-pigments, li-fillers, joalo-joalo, ho ntlafatsa ts'ebetso ea tsamaiso ea epoxy e thehiloeng metsing, e boetse e pata mefokolo esita le liphoso tse tebileng tsa metsi. tsamaiso ea epoxy, e tla eketsa ho hloka botsitso le ho rarahana ho feta Thobalano. Lahla mokhoa o rarahaneng le o bonolo, ela hloko mofuta oa metsi a thehiloeng ho epoxy resin le mokhoa oa ho phekola epoxy e thehiloeng metsing, ka nako e ts'oanang, ka ho laola mohloli oa epoxy resin e thehiloeng metsing le tlhahlobo ea metsi. epoxy resin ho fihlela khetho e potlakileng le e ntle ea sistimi ea epoxy e thehiloeng metsing Ho rala motheo oa moaho o moholo.
