Masana'antar masana'antar aluminum ta Chongqing ta bunƙasa cikin sauri a cikin 'yan shekarun nan, kuma a hankali ta fuskanci ƙasar baki ɗaya. Fasahar Anodizing tana ɗaya daga cikin hanyoyin da aka fi amfani da su a masana'antar aluminum ta masana'antu ta Chongqing. Sabbin masu amfani da yawa ba su san abubuwa da yawa game da tsarin anodizing ba, don haka bari mu ba ku cikakken bayani.
Tsarin kwararar maganin iskar shaka ga bayanan aluminum na masana'antu a Chongqing;
1. Maganin saman jiki.
Maganin saman, wanda kuma aka sani da pretreatment na saman, shine cire datti a saman bayanin aluminum ta hanyar amfani da abubuwan zahiri da sinadarai, don a iya fallasa shi ga jikin bayanin aluminum, wanda ya dace da maganin oxidation a saman bayanin aluminum a matakin ƙarshe.
2. Tsarin rage mai a saman ruwa.
Manufar tsarin rage mai shine a cire man shafawa na masana'antu, mai hana lalatawa da datti da ke haɗe da saman bayanin aluminum, don tabbatar da tsatsa mai daidai gwargwado na bayanin aluminum da kuma tsaftar tankin tsatsa mai alkali. Inganta ingancin maganin saman bayanin aluminum.
3. Tsarin cire sinadarin acid.
Tsarin etching acid na saman shine a gudanar da maganin etching acid na saman bayan an cire mai daga bayanin aluminum, kuma babban manufar cirewa shine a cire oxide da aka samar ta hanyar oxidation na wasu abubuwan ƙarfe a saman bayanin aluminum da kuma fim ɗin oxide da bayanin ya samar ta hanyar halitta; Bayan maganin lalata acid, ya zama dole a wanke shi nan da nan, kuma ya kamata a sarrafa zafin wankewa 50℃ da wuri don guje wa alamun kwarara a saman bayanin, sannan a tsaftace shi da ruwa mai gudu. Saboda bayanin aluminum yana ɗauke da jan ƙarfe, saman yana duhu bayan gwajin lalata acid, kuma yana buƙatar a jiƙa shi a cikin maganin nitric acid na tsawon mintuna 3-5 don sanya saman ya yi haske da azurfa.
4. Tsarin sassaka Alkaline.
Babban manufar tsarin etching na alkali shine cire sauran abubuwan da suka rage da kuma yadudduka masu canzawa a saman profile na aluminum yayin oxidation, da kuma kawar da lahani na karce da suka rage a saman profile na aluminum yayin murɗawa. Maganin etching na alkaline na saman profile na aluminum yana taka muhimmiyar rawa a cikin ingancin saman profile na aluminum gaba ɗaya.
5. Tsarin raba tsakani.
Manufar tsarin rage kiba shine a cire abubuwan da ba su da kyau kamar jan ƙarfe, manganese, baƙin ƙarfe, silicon, da sauransu waɗanda ba sa narkewa a cikin maganin alkaline da aka bari a saman bayanin aluminum bayan cire sinadarin acid da kuma cire sinadarin alkali. Gabaɗaya, hanyar kawar da sinadarin alkaline da aka bari a bayanin aluminum bayan cire sinadarin alkali shine a yi amfani da maganin nitric acid 30-50%. Don haɗa sinadarin aluminum mai yawan silicon, an zaɓi gaurayen acid na nitric acid da hydrogen fluoride tare da rabon girma na 1: 3. Silicon yana amsawa da hydrogen da hydrofluoric acid don samar da sinadarin fluosilicic, wanda ke barin saman aluminum.
6. Maganin Anodizing.
Hanyar maganin hadawan abu da iskar shaka ta anodic ita ce ana amfani da maganin a matsayin matsakaici, kuma ana zaɓar fitar da bakin don samar da fim ɗin oxide a saman bayanin aluminum, don haka bayanin aluminum yana da juriya sosai ga tsatsa. Saboda layin kariya da aka samu ta hanyar hadawan abu da iskar shaka ta anodic na bayanin aluminum yana da ƙarfi da juriya ga tsatsa, kauri na yau da kullun shine 10-12μ m, wanda zai iya inganta juriyar hadawan abu da iskar shaka ta bayanin aluminum da kyawun bayanin aluminum.
Tsarin hada sinadarin oxidation na anodic yana taka muhimmiyar rawa a cikin kyawun da dorewar bayanan aluminum na masana'antar Chongqing.
