Kuenzanisa kwekurapa mhedzisiro yebrous sulfate uye sodium bisulfa
Maitiro ekugadzira emagetsi anofanirwa kuve akabatanidzwa, uye mukushandiswa kwemagetsi ekunatswa, saka chirimwa chakashandiswa nechekuti chromate chichava chichava chicheka chicheka chicheka. Iyo chromium mumarara ine chromium ine hexavalent chromium, iyo ine chepfu uye yakaoma kubvisa. Hexavalent chromium inowanzoshandurwa kuenda kuThe Travenent chromium uye kubviswa. Kune kubviswa kwe chrome-ine electroplating trustrates Inowanzoshandiswa ndeye ferus sulfate uye lime kudzikisira nzira yekutanga uye sodium bisulfite uye alkali kuderedza nzira yekutanga.
1. Frous Sulfate uye lime kuderedza kudzikisira nzira
Ferrous Sulfate ndiyo yakasimba acid yekubatanidza neakasimba oxidation-kudzikisa zvivakwa. Ferrous Sulfate inogona kuderedzwa zvakananga neHexavalent chromium mushure mehydrolysis mumatare eChinese
Ferrous Sulfate Plus Lime Coagulant Rrom Not Romoned Yakasarudzika ine Chromium kubvisa uye mutengo wakaderera. Kechipiri, hapana chikonzero chekugadzirisa iyo pH kari kusati kwatanga kuwedzerwa sulfate, uye kungoda kuwedzera lime kugadzirisa iyo ph kukosha. Nekudaro, nekuda kwehuwandu hukuru hwekusuwa sulfate dosing yakakonzerawo kuwedzera kwakanyanya mutode yesimbi, kuwedzera mutengo wekurapwa kwerevi.
2, .SIDium bisulfite uye alkali kuderedza nzira yekutanga
Sodium bisulfite uye Alkali kuderedza precipitation chromate, iyo pH yemarara inogadziridzwa ku ≤2.0. Ipapo Bisulfite anowedzerwa kuderedza chromate kune tromium tromium, uye mvura yerwakasimudzwa ichisvika kuAlkali nodes 95%.
Iyo nzira yeSodium Bisulfite uye Alkali kuderedza zvakanyanyisa kubviswa Chrom Normodi Kupfuura Sulfal Sulfate, uye nguva yekurapa yakareba kwenguva refu, uye iyo phengo yePH inoda kugadziridzwa acid isati yarapwa. Nekudaro, kana tichienzanisa nekurapa kwematehwe ane sulfate, hazvigoni kubereka kukwenya kwakanyanya, kuderedza zvakanyanya mutengo wekurapa kwekurapa, uye sludge yakabatwa kazhinji kazhinji inogona kushandiswazve.
