A fannin samar da kayayyaki a masana'antu. Masu gyaran gashi, a matsayin muhimmin sashi na fasahar gyaran fuska, yana da mahimmanci don haɓaka kyawun samfurin, juriya da juriyar tsatsa. Yin amfani da galvanizing azaman maganin saman da aka saba amfani da shi. Ana amfani da shi sosai wajen magance saman ƙarfe. Wannan labarin zai yi cikakken bayani game da hanyoyi da dama na yin amfani da galvanizing, gami da cyanide galvanizing, zincate galvanizing, chloride galvanizing, da sulfate galvanizing. An tsara shi don samar wa masu karatu cikakken bayani game da fasaha.
1. Cyanide galvanization
Cyanide galvanizing, saboda ƙarfin watsawa da ingancin plating mai kyau. A wani lokaci yana da muhimmiyar rawa a masana'antar electroplating. Duk da haka, saboda yanayin gubar cyanide da kuma barazanar da ke tattare da muhalli. Amfani da shi yana da matuƙar ƙuntatawa. Duk da haka, haɓaka tsarin galvanizing mai ƙarancin cyanide (microcyanide). Yana ba da damar tabbatar da ingancin samfurin yayin da yake rage haɗarin muhalli. A ƙarƙashin tsarin galvanizing na cyanide, ingancin samfurin yana da kyau bayan an shafa ɓangaren kayan aikin caster. Musamman bayan an gama amfani da fenti mai launi, Launuka suna ci gaba da kasancewa masu haske na dogon lokaci.
2, sharuɗɗa da ra'ayoyi masu alaƙa da walda ta zincate galvanized caster
Tsarin yin amfani da zincate galvanizing wani zaɓi ne mai kyau ga muhalli maimakon cyanide galvanizing. A halin yanzu, galibi an raba su zuwa jerin "DPE" na Cibiyar Kare Kayayyaki ta Wuhan da jerin "DE" na Cibiyar Guangdian. Dukansu an yi su da zincate galvanized tare da ƙarin alkaline. Yana da halaye na tsarin layi na columnar plating, kyakkyawan juriya ga tsatsa, kuma ya dace da yin amfani da launi galvanizing. Tsarinsa na yau da kullun ya haɗa da NaOH, ZnO, da takamaiman ƙari. Misali, haɗin "DPE-II" da ethanolamine. Wannan tsari yana buƙatar kulawa mai tsauri game da abun da ke cikin maganin plating da yanayin aiki. kamar pH, zafin jiki, da yawan yanzu. don tabbatar da ingancin plating. Bayan samfurin ya bar tankin, dole ne ya bi jerin matakan bayan sarrafawa. kamar wankewa, gogewa, passivating da busarwa. don samun sakamako mafi kyau.
3. Gilashin Chloride
Ana amfani da tsarin galvanizing chloride sosai a masana'antar plating hardware na caster. Kashi ya kai sama da kashi 40%. Bayyanar passivated (shuɗi-fari ko azurfa-fari) na tsarin yayi daidai da na chrome plating. Kuma yana da ƙarancin farashi. Tsarin da aka saba amfani da shi don galvanizing chloride sun haɗa da KCl, ZnCl_2, H_3BO_3 (buffer), da takamaiman masu haske. Tsarin ya dace musamman don passivation fari (shuɗi-fari, azurfa-fari). Daga cikinsu, passivation na azurfa-fari saboda launinsa mai karko. Sau da yawa ana fifita shi azaman zaɓi na farko. Duk da haka. Ya kamata a lura cewa chloride galvanized coatings, lokacin da aka fallasa su ga iska na dogon lokaci, membrane yana da saurin canzawa. Yana shafar bayyanar da juriyar tsatsa na samfurin. Saboda haka. A aikace, ya zama dole a ɗauki matakan da suka dace don hana resursing.
4. Sinadarin sulfate
Tsarin galvanizing na sulfate, tare da ƙarancin farashi da dacewa da ci gaba da plating (misali, waya, tsiri, da sauransu). Wuri ne a masana'antar electroplating. Tsarin da aka saba amfani da shi don wannan tsari ya haɗa da ZnSO_4, H_3BO_3, da takamaiman masu haske. Ana sarrafa ƙimar pH na galvanizing na sulfate gabaɗaya tsakanin 4.5 da 5.5. Ta hanyar daidaita abun da ke cikin maganin plating da yanayin aiki, ana iya samun rufin A mai kyakkyawan juriya ga tsatsa da haske. Duk da haka. Idan aka kwatanta da sauran hanyoyin galvanizing, galvanizing na Sulfate na iya zama ɗan ƙasa da ƙasa dangane da sheƙi da daidaiton murfin.

Ya kamata ya dogara ne akan takamaiman yanayin amfani da buƙatun aiki na na'urar ƙara kuzari. Zaɓi tsarin ƙara ƙarfin kuzari da ya dace. A halin yanzu. Tare da ƙa'idodi masu tsauri na muhalli da ci gaba a fasahar ƙara ƙarfin ƙarfe, tsarin ƙara ƙarfin muhalli, inganci da araha mai kyau zai zama yanayin ci gaba a nan gaba.
