Farqiga u dhexeeya Galvanizing-Dip-kulul iyo galvanization makaanik

Galvanizing Hot Dip Galvanizing waa hab daawaynta oogada oo ku lug leh galinta qaybo hore loo daweeyay oo lagu shubay qubeyska zinc si loogu sameeyo falcelinta birta heerkulka sare si loo sameeyo daahan zinc ah Saddexda tillaabo ee galvanizing dip kulul waa sida soo socota:

① Dusha sare ee alaabta waxaa lagu kala diraa dareeraha zinc, iyo dusha birta ku salaysan waxaa lagu kala diraa dareeraha zinc si loo sameeyo weji daawaha birta zinc.

② Iions Zinc ee ku jira daaha daawaha waxay u sii fidayaan xagga matrixka si ay u sameeyaan lakabka xalka birta wadaagga ah; Birtu waxay samaysaa daawaynta birta zinc inta lagu jiro kala dirida xalka zinc waxayna sii wadaa inay u sii faafto agagaarka agagaarka Dusha sare ee lakabka daawaynta birta zinc waxaa lagu duuduubay lakab zinc ah, kaas oo qaboojiya oo kiraysanaya heerkulka qolka si uu u sameeyo dahaar. Waqtigan xaadirka ah, geeddi-socodka qulqulka kulul ee galvanizing ee boolalku wuxuu noqday mid aad u qumman oo xasilloon, dhumucda dahaarka iyo iska caabbinta daxalka waxay si buuxda u buuxin kartaa shuruudaha ka hortagga daxalka ee qalabka farsamada ee kala duwan. Si kastaba ha ahaatee, waxaa weli jira dhibaatooyinka soo socda ee wax soo saarka dhabta ah iyo rakibidda qalabka mashiinka:

1. Waxaa jira xaddi yar oo haraaga zinc ah oo ku yaal dunta bolt, kaas oo saameeya rakibaadda

2. Saamaynta xoogga isku xirka guud ahaan waxaa lagu gaaraa iyada oo la balaadhiyo gunnada mishiinada ee lowska iyo dib u garaacista ka dib marka la dhejiyo si loo hubiyo in ay ku habboon yihiin lowska galvanized kulul iyo boodhka. Inkasta oo tani ay hubiso ku habboonaanta xiraha, tijaabinta waxqabadka farsamada waxay inta badan dhacdaa inta lagu jiro habka xajinta, taas oo saameynaysa xoogga isku xirka ka dib rakibidda.

3. Saamaynta sifooyinka farsamada ee boolal-xoog-sare leh: Nidaamka galvanizing-ku-kulul-ku-kulul ee aan habboonayn wuxuu saameyn karaa saameynta adag ee boolal, iyo dhaqidda aashitada inta lagu jiro habka galvanizing waxay kordhin kartaa maadada hydrogen ee jaantuska 10.9 darajada sare ee boolal-xoog badan. , kordhinta awoodda ebrittlement hydrogen. Cilmi-baaristu waxay muujisay in sifooyinka farsamada ee qaybaha dunta ah ee boolal-xoog-sare ah (fasalka 8.8 iyo wixii ka sareeya) ka dib galvanizing-kuleylku waxay leeyihiin heer gaar ah oo dhaawac ah.

Galvanizing makaanikku waa habraaca ka faa'iidaysta dhigaalka kiimikaad ee adsorption, iyo shil farsamo si loo sameeyo dahaarka budada birta ah ee dusha sare ee shaqada heerkulka qolka iyo cadaadiska. Isticmaalka habkan, dahaarka birta ah sida Zn, Al, Cu, Zn-Al, Zn-Ti, iyo Zn-Sn ayaa lagu samayn karaa qaybaha birta, iyagoo siinaya ilaalin wanaagsan substrate-ka birta. Habka galvanizing farsamada laftiisa ayaa go'aaminaya in dhumucda daahan ee dunta iyo jeexjeexyadu ay ka khafiifsan yihiin kuwa sagxadaha siman. Ka dib marka la dhajiyo, lawska uma baahna in dib loo taabto, boolaladaha ka sarreeya M12 uma baahna xitaa inay xafidaan dulqaadka. Ka dib marka la dhajiyo, ma saameynayso ku habboonaanta iyo sifooyinka farsamada. Si kastaba ha ahaatee, xajmiga walxaha budada zinc ee loo isticmaalo habka, xoojinta quudinta inta lagu jiro habka dajinta, iyo muddada quudinta waxay si toos ah u saameeyaan cufnaanta, fidsanaanta, iyo muuqaalka dahaarka, taas oo saameynaysa tayada daboolka.
