La dhajiyay 2018-11-12Dacromet dacromet, oo sidoo kale loo yaqaan daahan zinc flake, ayaa faa'iido u leh in kan dambe aan la gaari karin marka la barbar dhigo farsamooyinka galvanized electro galvanized caadiga ah iyo kuleyl kulul.Daahan Zinc flake wuxuu leeyahay faa'iidooyinka soo socda:
#1.Iska caabbinta daxalka oo aan caadi ahayn
Ilaalinta korantada ee korantada ee zinc, saamaynta gaashaanka ee xaashida zinc / aluminiumka iyo saamaynta is-dayactirka ee chromate waxay ka dhigaysaa dahaarka Dacromet si aad u adkeysi badan u leh daxalka marka dahaarka Dacromet lagu tijaabiyo buufinta cusbada dhexdhexaadka ah.Waxay qaadataa ilaa 100 saacadood si loo dhajiyo daahan 1um, taas oo 7-10 jeer ka wanaagsan daawaynta galvanizing dhaqameed.Tijaabada buufinta milixda ee dhexdhexaadka ah waxay socon kartaa in ka badan 1000 saacadood (dahaarka leh dhumucdiisuna tahay 8um ama ka badan), iyo qaar xitaa ka sarreeya, tani suurtagal maaha lakabyo galvanized ah oo kulul.
#2.Iska caabbinta kulaylka wanaagsan
Tan iyo markii Dakoro-dahaarka chromic acid polymer uusan lahayn biyo crystal iyo barta dhalaalaysa ee xaashida aluminium/zinc waa sare, daahan ayaa iska caabbinta daxalka heer-sare ah aad u fiican.Dahaarka Dacromet wuxuu leeyahay heerkulka iska caabinta kulaylka ee 300 ° C. Waxaa loo isticmaali karaa si joogto ah muddo dheer 250 ° C. Iska caabbinta daxalka ayaa ku dhawaad wax saameyn ah kuma yeelan, iyo filimka passivation ee dusha sare ee lakabka zinc electroplated waa la burburiyaa agagaarka 70 ° C, iyo iska caabbinta daxalka waa hoos u dhac fiiqan.
#3.Jilicsanaansho hydrogen ma jiro
Inta lagu jiro daaweynta farsamada ee Dacromet, ma jiraan wax dhaqid acid, electrodeposition, koronto de-saliid, iwm, iyo ma jiraan falcelin electrochemical ee evolution hydrogen ay keento habka electro-galvanizing, sidaas darteed maaddadu ma keeni doonto hydrogen ebrittlement.Sidaa darteed waxay si gaar ah ugu habboon tahay wax ka qabashada qaybaha laastikada iyo qalabka shaqada ee xoogga badan.
#4.The goodrecoatability
Muuqaalka daaha Dacromet waa qalin-cawlan oo leh dhejis wanaagsan oo substrate ah iyo dahaar kala duwan.Waxaa loo isticmaali karaa sida lakabka sare ama sida asaasiga ah ee dahaarka kala duwan.Dareen-celinta elektaroonigga ah waxay ka dhex dhacdaa biraha dhexdooda sababtoo ah kala duwanaanshiyaha suurtagalka ah.Lakabyada galvanized, labada lakab ee ku salaysan birta iyo aluminiumku waa kuwo u adkaysta korantada oo aad u yareeya caabbinta daxalka.Lakabka ka hortagga daxalka ee Dacromet, maadaama ka-hortagga ka-hortagga-ku-saleysan yahay uu ku saleysan yahay xiniinyaha acid chromic iyo ilaalinta allabaryada la xakameeyey ee lakabka zinc-ka ee qolofleyda ah, wax daxalka elektiroonigga ah lama soo saaro, sidaa darteed isticmaalka Zn waa mid la xakameynayo daxalka Al waa la xakameeyey.
#5.Permeability heer sare ah
Dheecaanka daawaynta Dacromet waxa uu dhex geli karaa isku-xidhka cidhiidhiga ah ee qaybta shaqada si uu u sameeyo dahaarka aan daxaluhu lahayn.Haddii habka korantada loo isticmaalo, dusha gudaha ee xubinta tuubada ayaa si adag loo dhejiyay sababtoo ah saameynta gaashaanka.Si kastaba ha ahaatee, sababtoo ah daawaynta Dacromet waxaa lagu dabaqaa daahan oo leh awood wanaagsan, waxaa lagu dabaqi karaa si loo hagaajiyo awoodda ka hortagga miridhku gudaha iyo dibaddaba.
#6.Wasaaq malaha
Marka zinc electroplating, waxaa jira dhibaato dheecaan bulaacada ka kooban zinc, alkali, chromic acid, iwm, taas oo keeni doonta wasakh weyn.Heerkulka zinc dip kulul waa sarreeyaa, iyo uumiga zinc ee la sii daayay iyo HCL waxay khatar ku yihiin caafimaadka aadanaha.Inta badan soosaarka zinc kulaylka ee hadda jira waa in laga fuliyaa meel ka fog magaalooyinka iyo miyiga.Habka Dacromet wuxuu abuuray beer cusub oo ilaalinta daxalka birta ah.Sababtoo ah daawaynta Dacromet waa nidaam xiran, walxaha firfircoon inta lagu jiro habka dubista waxay u badan yihiin biyaha, kuma jiraan walxo kale oo waxyeello leh oo la xakameeyey, mana laha wax wasakh ah deegaanka.
