Qaarkiin ayaa laga yaabaa in ay weli qaataan habka daawaynta dusha sare ee galvanizing-kulul, taas oo u muuqata in yar oo duug ah.Dacromet dacromet waa doorasho aad u fiican adiga.Qaybaha birta iyo birta ah ee u baahan difaac dheeraad ah oo ka ilaaliya daxalka milixdu waa galvanized kulul ama Dacromet la dahaadhay, labaduba waa dahaarka Zinc.Dacromet waa magac sumad leh oo leh codsi "zinc flake" oo rukhsad leh.Mararka qaarkood magaca astaantan si dabacsan ayaa loo isticmaalaa in lagu qeexodaahan zinc galvanized.Maqaalkan, faa'iidooyinka nidaamka daahan Dacromet ayaa si faahfaahsan loogu sharxi doonaa si ay kaaga caawiso inaad si fiican u fahanto.
Farqiga u dhexeeya Dacromet iyo habka galvanization-ku-kulul
Habka Dacromet waxa lagu dubaa ilaa 500F ka dib codsiga, halka habka galvanization-ku-kulul lagu sameeyo heerkulka zinc la dhalaalay (780F) ama ka sii kulul.Midda dambe, waxaa laga yaabaa inaad heshid xoogaa dhimista walaaca ee qaybaha dhib kugu ah.
Galvanizing kulul oo la rusheeyey ayaa jirtay muddo dheer waana la yaqaan.Qaybta waxaa lagu dhex shubaa isku dhafka zinc la dhalaaliyay oo heerkulkiisu yahay 460 ℃ kaas oo la falgala kaarboon dioxide si uu u sameeyo zinc carbonate.
Dacromet waxay leedahay iska caabin kulayl oo heer sare ah;daahan galvanized caadiga ah ayaa tusi doona dildilaaca yar oo ka sarreeya 70 ℃, iyo discolor iyo caabbinta daxalka ay si weyn loo dhimi doonaa at 200-300 ℃.
Heerkulka daawaynta ee filimka Dacromet anti-corrosion waa 300 ℃, sidaa darteed birta dusha sare ma beddeli doonto muuqaalkeeda oo wali waxay sii wadi kartaa daxalka kulaylka adag ee u adkaysta xitaa haddii la dhigo heerkul sare muddo dheer.
Si ka duwan daahan galvanized kulul-muquufin,daahan Dacrometma laha wax-marin hydrogen ah.Qaybaha birta ah ee lagu daweeyay Dacromet waxay samayn karaan filimka xitaa meelaha bannaan ee ugu fiican iyo daaha ka-hortagga daxalka oo leh awood qoto dheer.Dahaarka lebbiska ah ayaa sidoo kale lagu dabaqaa gudaha qaybaha tuubada oo leh awood wanaagsan sababtoo ah xalka Dacromet waa biyo-milmi.
Faa'iidooyinka daahan Dacromet
1. Iska caabbinta daxalka sare
Dhumucda lakabka filimka Dacromet waa 4-8μm kaliya, laakiin saameynteeda ka hortagga miridhku waa in ka badan 7-10 jeer oo ah electro-galvanizing dhaqameed, galvanizing kulul ama habka daahan.Ma jiro daxal cas oo ku dhici doona qaybaha caadiga ah iyo kala-goysyada tuubooyinka ee lagu daaweeyay habka Dacromet ee tijaabada buufinta milixda in ka badan 1,200h.
2. Haydaroojiin qallafsan ma jiro
Habka daawaynta ee Dacromet ayaa go'aamisa in aysan jirin wax soo saarka hydrogen ee Dacromet, sidaas darteed Dacromet waxay ku habboon tahay daahan qaybaha walaaca.
3. Iska caabbinta kulaylka badan
Dacromet waxay iska caabin kartaa daxalka heerkulka sare, iyo kulaylka u adkaysta wuxuu gaari karaa in ka badan 300 ℃.Si kastaba ha ahaatee, qolof ama xoqid ayaa dhici doonta si fiican habka galvanizing-dhaqameedka marka heerkulku gaaro 100 ℃.
4. Ku dheggan wanaagsan iyo dib u soo celinta
daahan Dacrometwuxuu leeyahay adhesion qumman oo leh substrate birta iyo dahaarka kale ee dheeraadka ah.Way u fududahay qaybaha la daweeyay inay ku buufiyaan midabaynta, iyo ku-xidhka leh daahan organic ayaa xitaa ka xoog badan filimka fosfooraska.
5. Daahfurnaan heer sare ah
Sababtoo ah saamaynta gaashaanka elektrostatic, way adagtahay in lagu dhejiyo godadka qoto dheer iyo jeexjeexyada shaqada iyo gidaarka gudaha ee tuubada, sidaas darteed qaybaha kor ku xusan ee shaqada laguma ilaalin karo koronto.Dacromet waxay geli kartaa qaybahan shaqada si ay u sameeyaan daahan Dacromet ah.
6. Wax wasaq ah iyo khataro dadwayne
Dacromet ma soo saarto biyo wasakh ah ama gaas wasakh ah oo wasakheeya deegaanka inta lagu jiro habka wax soo saarka, farsamaynta iyo dahaadhka qalabka shaqada, markaa looma baahna saddex daaweyn oo qashinka ah, sidaas darteed hoos u dhigista kharashka daaweynta.
7. Saacadaha buufinta milixda oo dheer
In ka badan 500 oo saacadood oo buufin milix ah marka la barbar dhigo ugu badnaan 240 saacadooddaahan zinc galvanized.Buufinta milixdu waa imtixaam halbeegga warshadaha halkaas oo qaybaha la dhigo heerkul la kantaroolo oo ah 35 ℃ laguna sakhiray buufin joogto ah oo ah sodium-chloride solution.Tijaabada buufinta milixdu waxay ku duuban tahay saacado waxayna dhammaataa marka miridhku casaanka ahi ka soo muuqdo qaybaha.
