Ⅰ- AcidPickling
1.-Ma'anarAcid-Pickling: Ana amfani da acid don cire ma'aunin ƙarfe oxide ta hanyar sinadarai a wani takamaiman taro, zazzabi, da sauri, wanda ake kira pickling.
2.- Acid-Rarraba Pickling: Dangane da nau'in acid, an raba shi zuwa pickling na sulfuric acid, pickling hydrochloric acid, pickling na nitric acid, da pickling hydrofluoric acid.Dole ne a zaɓi kafofin watsa labarai daban-daban don tsinke bisa kayan ƙarfe, kamar ɗaukar ƙarfe na carbon da sulfuric acid da hydrochloric acid, ko ɗaukar bakin karfe tare da cakuda nitric acid da hydrofluoric acid.
Dangane da siffar karfe, an raba shi zuwa tsinken waya, tsinken jabu, tsinken farantin karfe, tsinken tsiri, da sauransu.
Dangane da nau'in kayan girki, an raba shi zuwa ɗimbin tanki, daɗaɗɗen ci gaba mai ci gaba, ci gaba mai ci gaba, da tsinkar hasumiya.
3.- Ka'idar pickling acid: Tsabar acid shine tsarin cire ma'aunin ƙarfe oxide daga saman ƙarfe ta amfani da hanyoyin sinadarai, don haka ana kiransa pickling.Iron oxide Sikeli (Fe203, Fe304, Fe0) kafa a saman karfe bututu su ne asali oxide da ba su narkewa a cikin ruwa.Lokacin da aka nutsar da su a cikin maganin acid ko kuma a fesa su da maganin acid a saman, waɗannan asali na oxide na iya fuskantar jerin canje-canjen sinadarai tare da acid.
Saboda sako-sako, porous, da fashe yanayin sikelin oxide akan saman tsarin ƙarfe na carbon ko ƙaramin ƙarfe, haɗe tare da maimaita lanƙwasawa na sikelin oxide tare da tsiri karfe yayin daidaitawa, daidaitawar tashin hankali, da sufuri akan pickling line, wadannan pore fasa kara karuwa da fadada.Sabili da haka, maganin acid yana amsawa tare da sikelin oxide da sinadarai kuma yana amsawa tare da ƙarfe na ƙarfe na ƙarfe ta hanyar fasa da pores.Wato a farkon wankin acid din, ana aiwatar da halayen sinadarai guda uku tsakanin ma'aunin iron oxide da karfen karfe da kuma maganin acid a lokaci guda. yana haifar da iskar hydrogen, wanda da injina ya bare ma'aunin oxide (tasirin peeling na injina) Haɗin hydrogen da aka samar yana rage baƙin ƙarfe oxides zuwa ferrous oxides waɗanda ke da saurin haɓakar halayen acid, sannan ya amsa da acid don cirewa (raguwa).
Ⅱ-Abin sha'awa/Rashin kunnawa/Deactivation
1.- Ka'idar Passivation: Za'a iya bayanin tsarin wucewa ta hanyar ka'idar fim na bakin ciki, wanda ke nuna cewa passivation shine saboda hulɗar tsakanin karafa da abubuwan da ke haifar da oxidizing, samar da siriri, mai yawa, da kyau an rufe shi, kuma da tabbaci adsorbed passivation fim akan saman karfe.Wannan Layer na fim ɗin yana kasancewa a matsayin lokaci mai zaman kansa, yawanci wani fili na karafa mai oxidized.Yana taka rawa wajen raba karfen gaba daya daga tsaka-tsaki mai lalata, yana hana karfen shiga cikin mu'amalar gurbataccen yanayi, ta yadda zai dakatar da rushewar karfen da kuma samar da yanayin da ba zai yiwu ba don cimma sakamako na hana lalata.
2.- Amfanin wuce gona da iri:
1) Idan aka kwatanta da na gargajiya na jiki hatimi hanyoyin, passivation jiyya yana da halayyar cikakken ba kara kauri na workpiece da canza launi, inganta daidaici da kuma kara darajar da samfurin, yin aiki mafi dace;
2) Saboda rashin amsawa yanayin tsarin wucewa, ana iya ƙarawa da amfani da wakili akai-akai, yana haifar da tsawon rayuwa da ƙarin tsadar tattalin arziki.
3) Passivation inganta samuwar oxygen kwayoyin tsarin passivation fim a kan karfe surface, wanda shi ne m da kuma barga a yi, kuma yana da kai gyara sakamako a cikin iska a lokaci guda.Saboda haka, idan aka kwatanta da gargajiya Hanyar shafi antirust man fetur, passivation fim kafa ta passivation ne mafi barga da kuma lalata resistant.Yawancin tasirin caji a cikin Layer oxide suna da alaƙa kai tsaye ko a kaikaice ga aiwatar da iskar oxygenation na thermal.A cikin kewayon zafin jiki na 800-1250℃, Tsarin oxidation na thermal ta amfani da busassun iskar oxygen, rigar oxygen, ko tururin ruwa yana da matakai guda uku masu ci gaba.Na farko, iskar oxygen da ke cikin yanayin muhalli ta shiga cikin Layer oxide da aka samar, sannan iskar oxygen ta yadu a ciki ta hanyar silicon dioxide.Lokacin da ya isa wurin dubawar Si02-Si, yana amsawa da silicon don ƙirƙirar sabon silicon dioxide.Ta wannan hanyar, ci gaba da aiwatar da tsarin shigar da iskar oxygen yana faruwa, yana haifar da siliki kusa da mu'amala don ci gaba da canzawa zuwa siliki, kuma Layer oxide yana girma zuwa ciki na wafer silicon a wani ƙimar.
Ⅲ- Phosphating
Maganin phosphating wani nau'in sinadari ne wanda ke samar da Layer na fim (fim ɗin phosphating) a saman. Ana amfani da tsarin jiyya na phosphating a kan saman karfe, tare da manufar samar da fim mai kariya don ware karfe daga iska da kuma hana lalata;Hakanan za'a iya amfani da shi azaman firamare don wasu samfuran kafin zanen.Tare da wannan Layer na fim din phosphating, zai iya inganta mannewa da juriya na lalata launi na fenti, inganta kayan ado, kuma ya sa saman karfe ya fi kyau.Hakanan yana iya taka rawar mai a wasu matakan aikin sanyi na ƙarfe.
Bayan phosphating jiyya, da workpiece ba zai oxidize ko tsatsa na dogon lokaci, don haka aikace-aikace na phosphating jiyya ne sosai m, kuma shi ne da aka saba amfani da karfe surface jiyya tsari.Ana ƙara amfani da shi a masana'antu kamar motoci, jiragen ruwa, da masana'anta.
1.- Rarrabewa da aikace-aikacen phosphating
Yawancin lokaci, jiyya na saman zai gabatar da launi daban-daban, amma maganin phosphating zai iya dogara ne akan ainihin bukatun ta amfani da nau'o'in phosphating daban-daban don gabatar da launi daban-daban.Wannan shine dalilin da ya sa muke yawan ganin maganin phosphating a cikin launin toka, launi, ko baki.
Iron phosphating: bayan phosphating, saman zai nuna launin bakan gizo da kuma shuɗi, don haka ana kiran shi launi phosphorus.Maganin phosphating yafi amfani da molybdate azaman albarkatun ƙasa, wanda zai samar da fim ɗin phosphating launi na bakan gizo akan saman kayan ƙarfe, kuma ana amfani dashi galibi don fentin ƙasan Layer, don cimma juriya na lalata kayan aikin da haɓaka mannewa. na shafi shafi.
JINBAICHENG ne manyan karfe bututu factory a kasar Sin, Za mu iya samar da kuma samar da sumul karfe bututu, welded bututu, ssaw bututu, gi bututu da surface na Acid-Pickling, Abin sha'awa, da kuma Phosphating.Muna ba da sabis na tela na al'ada kuma za mu ba ku mafita mafi kyau don ayyukanku.Tuntube mu don farashi mafi kyau:https://www.sdjbcmetal.com/steel-pipe-series/ imel:jinbaichengmetal@gmail.com ko kuma a WhatsApphttps://wa.me/18854809715
