Whakamahi
Ko tenei hua ko te rauemi matua matua mo te cyide-koreutu-kore-kore. I te wa i hangaia ai ki roto i te otinga raima parakore-koreutu, he pai te kaha hereni i te wa e tika ana te papapa ki te konutai rino. He maeneene te paninga, he pai hoki te pua. Ko te tikanga, ko te inenga o te hua me te ihirangi o te 60% ko te 100 - 120 ml / l. Ko te inenga o te parahi konutai he 15 - 20 g / l. I tua atu, i mua i te electropllating, te rumaki i nga waahanga whakatikatika i te 1% - 2% o tenei hua kia huri ai nga waahanga ki te whenua whakahohe. Electroplating i muri i tenei mahi ka pai ake te whakapai ake i te paanga. Hydroxyethylylidene dishosphonic waikawa dishosphonic (hedp) he momo hou o te kaihoko miihini-kore-iti-iti. Ka whakamahia hei kaihoko matua mo te whakakao o te kounga kai i roto i te punaha wai ma te hauhautanga, e takaro ana ki te aukati i te aukati me te aukati i te aukati. Ko tenei hua tetahi o nga kaihoko waikawa wai waikawa wai waikawa. Kei reira ano etahi atu momo o tenei momo hua i hangaia i Haina, penei i te Amino Trrimethylene Phosphinic Phosphinic Phosphinic i te mutunga o nga tau 1970. Ko te putanga o tenei momo o nga kaihoko maimoatanga wai kua whai i te hangarau maimoatanga wai matatau na te taahiraa nui. I whakaritea ki te Polyphosphates Inorganic, he waikawa polyphosphosphonic pai, kaore e taea te tu ki te pāmahana tino, me whai i nga waahanga iti o te kohukohu me te aukati. He momo ahua o nga kaikiri i te cathodic me te ahua ano hoki o nga kaikohuru-kore-stobitetors. I te wa e whakamahia ana me etahi atu o nga kaihoko maimoatanga wai, ka whakaatuhia e ratou he tino painga. He pai te kaha o a raatau mo nga rai whakarewa penei i te konupūmā, konupora, te parahi, me te konutai. He pai tonu te painga o te rongoa o enei konganuku, penei i te caso4, Caco3, MgIO3, me etahi atu e whakamahia nuitia ana i te hangarau maimoatanga wai. Ka whakamahia nga reagent phosphoryliting mo te karaati me te pyranose.
Pahi me te tuku
Te Whakawhiwhinga: 25kg hei whakaritenga kiritaki.
Tukunga: No te matū noa ka taea te tuku ma te tereina, te moana me te hau.
Kia mau ki te rokiroki
Ora Stulf: 24 marama mai i te rā o te hanga i te kohinga tuuturu i penapena i roto i te waahi maroke hauhautanga mai i te ra tika, te wai.
Te whare putunga, te whakamaroke pāmahana pāmahana, ka wehea mai i te oxidants, te waikawa.
