Momo rehu raina whakaputa i mua i te maimoatanga
Ko te whakamaarama i mua i te paninga ko te whakakore (degreasing), te tango waikura, te phosphating e toru nga wahanga.Phosphating Ko te hononga pokapū, degreasing me te waikura tango ko te tukanga faaineineraa i mua i te phosphating, na i roto i te mahi production, e kore e tika tango tatou mahi phosphating rite te arotahi, engari ano timata i te whakaritenga o te kounga phosphating, mahi i te mahi pai i tua atu ki te tango i te hinu me te waikura, ina koa ka aro ki te awe tahi i waenga i a raatau.
Te whakaheke hinu
Na te whakawhanaketanga o te umanga, ko te whakamarumaru o te taiao me te whakapai ake o nga tikanga mahi kua waiho hei maaharahara o te tangata.Na reira, me whai whakaaro te hiahia o te tiaki taiao i te wa e whiriwhiri ana i nga kaihoko.Na reira, ko te kowhiringa o te kaihoko tango hinu e hiahia ana ki te whakarite ngawari, he kaha te kaha deconfouling, kaore he konutai hydroxide, silicate, OP emulsifier me etahi atu waahanga he uaua ki te horoi i te pāmahana rūma, ngawari ki te horoi i te pāmahana rūma, kaore he paitini. matū, e kore e whakaputa hau kino, tikanga mahi pai.Ko te kowhiringa o te tango waikura me whakauru nga kaiwhakatairanga, te aukati waikura me te aukati, ka taea te whakapai ake i te tere o te tango waikura, te aukati i te mea mahi mai i te waikura me te hauwai embrittlement, ka pai ake te aukati i te kohu waikawa.He tino tika ki te aukati i te kohu waikawa, ka puta i roto i te tukanga o te kohu kohu waikawa, te pirau o nga taputapu me te tipu, ehara i te mea noa te whakapoke i te taiao, ka taea te pirau niho, te whero o te niho conjunctival, te roimata, te mamae, te korokoro maroke, te mare me etahi atu tohu. , na whai hua ki te aukati i te kohu waikawa, ehara i te mea ko te tiaki i te taiao anake, hei oranga mo nga hiahia o te kaimahi.
Te horoi wai
Ko te horoi i muri i te tango hinu me te tango waikura, ahakoa no te mahi awhina i mua i te peita, me nui te aro.I muri i te tango hinu me te tango waikura, he maamaa te mata o te mea mahi ki te piri ki etahi surfactants kore-katote me te CL-.Ki te kore e tino horoia nga toenga o enei matū, tera pea ka angiangi te kiriata phosphating, te koha raina, tae atu ki te phosphating.Na reira, ki te whakapai ake i te kounga o te horoi wai i muri i te tango hinu me te tango waikura, he mea tika ki te haere i roto i te maha o nga horoi, e rua nga horoi, te wa 1-2min, me te whakakapi i nga wa katoa i te wai ki te whakarite ko te uara PH o te wai kei waenganui i te 5-7 .
Phosphating
Ko te phosphating pera-ka karanga, e pā ana ki te workpiece whakarewa i muri i roto i dihydrogen phosphate maimoatanga otinga waikawa, tauhohenga matū me i roto i tona mata ki te whakaputa i te apa o te pūmau kiriata phosphate rewa, ka huaina te kiriata phosphating kiriata.Ko te kaupapa matua o te kiriata phosphating ko te whakanui ake i te piri o te paninga me te whakapai ake i te aukati waikura o te paninga.He maha nga tikanga o te phosphating, kia rite ki te pāmahana o te phosphating, ka taea te wehea ki te teitei te pāmahana phosphating (90-98 ℃), te pāmahana reo phosphating (60-75 ℃), iti pāmahana phosphating (35-55 ℃) me te pāmahana noa phosphating.
Te weriweri
Ko te hangarau passivation o te kiriata phosphating e whakamahia nuitia ana i Amerika Te Tai Tokerau me nga whenua Pakeha.Ko te hangarau passivation kei runga i nga ahuatanga o te kiriata phosphating ano.He kikokore te kiriata phosphating, te tikanga i roto i te 1-4G /m2, ko te morahi e kore e neke atu i te 10g/m2, he nui te waahi pore kore utu, a he iti te aukati o te waikura o te kiriata ano.Ētahi ara i roto i te tukanga whakamaroke i runga i te waikura kōwhai tere, i muri i te phosphating he maimoatanga kati passivation, ka taea e phosphating kiriata pore kitea hāora whakarewa, ranei te hanganga o te apa passivation, phosphating kiriata e taea te purei i te whakakī, hāora, hanga phosphating kiriata pūmau i roto i te huru.
Te whakamaroke o te kiriata phosphating
Ko te whakamaroke i te kiriata phosphating ka taea te takaro i nga mahi e rua, i tetahi taha, ko te whakarite mo te tukanga e whai ake nei ki te tango i te wai i runga i te mata o te kiriata phosphating, i tetahi atu ringa, ko te whakapai ake i te aukati o te waikura o te kiriata. i muri i te paninga.
Hei whakarite i tetahi raina whakamaoritanga paninga, me whakaoti te hoahoa tukanga i mua i te hoahoa, te hanga me te whakaurunga o nga taputapu kore-paerewa.Na reira, ko te hoahoa tukanga te turanga o te raina whakaputa, a ko te huarahi tika me te whaitake ka whai hua pai ki te mahi whakaputa me te kounga o te hua.
Ka whakamahia mo nga momo peita mahi katoa, ka taea te whakarite etahi atu tauira.

Raina whakangao hiko kaa waka
Ko te peita hiko e wha nga tukanga tukutahi e wha 1. Electrophoresis: i raro i te mahi a te papa hiko o naianei, ko nga matūriki colloidal pai me te toraro ki te toraro, te nekehanga pai o te ahunga, e kiia ana ko te kauhoe.2. Electrolysis: ka mahia te tauhohenga whakaheke o te waikura ki runga i te hiko, engari ka puta te ahuatanga o te waikura me te whakaheke i runga i te ...
