Coating process kuyerera kwekaviri-layer epoxy poda anticorrosive yekugadzira mutsara

Iyo yekupfekedza maitiro eiyo kaviri-layer fusion yakasungirirwa epoxy poda yekunze anti-corrosion yekugadzira mutsara ndeiyi inotevera:

Tsanangudzo pfupi yematanho makuru:

(1) Pre-processing

Magokora anofanirwa kutariswa nekuona rimwe nerimwe, uye chitarisiko uye saizi kutsauka kunofanirwa kubviswa kana zviyero zvepombi zvesimbi zvisina kusangana; acetone uye mamwe organic solvents anofanira kushandiswa kuchenesa pamusoro pemagokora ane mafuta; magokora anotumirwa negungwa anoongororwa ma chlorides Kana zvirimo zvinopfuura 20mg/m2, geza nemvura yakachena inodzvanywa.

(2) Kuputika kwepfuti uye kukanganisa

Gokora rinofamba pamutsara wakaita serin’i rekutapurirana ropinda mukamuri rekuchenesa kuti riputirwe nepfuti uye kubvisa ngura.

(3) Kuongorora uye kurapwa mushure mekubvisa ngura

Danho rekutanga nderekuita ongororo yekuona kugadzirisa kana kubvisa mapombi esimbi asina kukwana. Mukuwedzera, iyo anchor line yekuyeresa chiridzwa ichashandiswa kuona kudzika kwemutsara weanchor zvinoenderana neyakatemwa yekuongorora frequency. Chekupedzisira, iyo ngura yekubvisa nhanho ichaongororwa zvinoenderana nemufananidzo kana giredhi rekuenzanisa sampuli.

(4) Kudziya

Shandisa coil yepakati pema frequency kupisa pamusoro pegokora kusvika yasvika patembiricha inodiwa nependi. Kuti unyatso kudzora kupisa kwepamusoro kwegokora, thermometer inofanirwa kushandiswa kuramba ichiyera.

(5) Kupfapfaidza

Panguva yekupfapfaidza, gokora rinofamba pamutsara wakaita serin’i rekutapurirana ropinda muimba yekupfapfaidza. Zvikamu zvemukati nekunze zvakapfapfaidzwa zvakatevedzana, uye kupfapfaidza kwekunze kunofanira kuitwa musati mutsara wemukati waiswa gelatinized.

(6) Kutonhora kwemvura

Inofanirwa kuve nechokwadi chekuti kupfekedza kwacho kwanyatsopora mvura isati yatonhora.

(7) Kuongororwa kwepamhepo

Kana tembiricha yepasi pegokora yadzikira kupfuura 100°C, spark leak detector inoshandiswa kuona inobuda pamajasi ese, uye inobuda inofanira kuiswa chiratidzo nekugadziridzwa zvinoenderana nezvinodiwa mushure mekunge vange vasina Indaneti.
