Hal baakidh oo ka kooban 96% zinc oo ku jira filimka qalalan, beddelka waxqabadka ka-hortagga daxalka ilaa qulqulka kulul
Sharaxaada
ZINDN waa hal baakidh oo daahan galvanizing ah oo ka kooban 96% boodhka zinc ee filimka qalalan oo bixiya ilaalinta cathodic iyo birta birta ah labadaba.
Waxaa loo isticmaali karaa ma aha oo kaliya nidaam gaar ah si ay u noqoto waxqabadka lidka-hortagga beddelka ah ee galvanizing kulul, laakiin sida asaasiga ah ee nidaamka duplex ama nidaamka daahan saddex-lakabka ah ee ZINDN.
Waxaa lagu dabaqi karaa buufinta, cadayashada ama ku rogrogmada substrate bir nadiif ah oo qallafsan oo kala duwan oo jawiga jawiga ah.
Ilaalinta Cathodic
Daxalka elektiroonigga ah, birta zinc iyo birta ayaa xiriir la leh midba midka kale, iyo zinc-ka leh awoodda korantada hoose ee loo isticmaalo sida anode-ka, kaas oo si joogto ah u luminaya electrons oo uu daxaloobay, taas oo ah, anode allabari;halka birta lafteeda loo isticmaalo sida cathode, taas oo kaliya gudbisa electrons oo aan is beddelin, sidaas darteed waa la ilaaliyaa.
Maadada Zinc ee ku jirta lakabka galvanizing ee ZINDN ayaa ka badan 95%, nadiifinta boodhka zinc ee la isticmaalayna waa ilaa 99.995%.In kasta oo lakabka galvanizing-ku uu yara dhaawacmay, birta ka hoosaysa lakabka zinc-ka ma daxaloobayn doono ilaa ay si buuxda u wada baabbi'iso zinc-ka, iyo dhanka kale, waxay si wax ku ool ah uga hortagi kartaa faafitaanka miridhka.
Ilaalinta caqabada
Habka falcelinta khaaska ah ayaa ka dhigaysa lakabka galvanizing ee ZINDN in lagu sii daawayn karo iyada oo la raacayo wakhtiga codsiga ka dib, samaynta caqabad cufan, si wax ku ool ah u go'doominta arrimaha daxalka, oo si weyn u wanaajinaya awoodda ka hortagga daxalka.
ZINDN waxay isku daraa sifooyinka labada sifo ee ka-hortagga daxalka mid ka mid ah, jebinta xaddidaadda saamiga-saldhigga ee dahaarka caadiga ah, iyo helitaanka awoodda ka-hortagga daxalka ee muddada-dheer.
95% boodhka zinc ee lakabka galvanizing ee ZINDN filimka qalalan, cufnaanta daxalka hadda aad ayuu uga sarreeyaa kan dahaarka hodanka ku ah zinc
Kordhinta boodhka zinc ee lakabka filimka qalalan, cufnaanta hadda jirta ayaa si weyn u kordhin doonta, awoodda korantada ee ka hortagga daxalka ayaa sidoo kale si weyn u kordhin doonta.
Faa'iidooyinka ZINDN
Ka-hortagga daxalka ee muddada-dheer
Firfircoon + guryaha ilaalinta dadban, tijaabada buufinta milixda ilaa 4500 saacadood, si fudud loo gaadho ilaa 25+ sano oo cimriga ka-hortagga daxalka.
adhesion xoog leh
Tiknoolajiyada wakiilka fiyuuska ee la sameeyay ayaa si buuxda u xallisay dhibaatada adhesion ee boodhka zinc sare (> 95%) ee filimka qalalan.4% jajabka tirada badan ee wakiilka fiyuuska waxay si adag u xidhi kartaa 24 jeer miisaankeeda boodhka zinc waxayna ka dhigi kartaa isku xidhka substrate iyo adhesion ilaa 5Mpa-10Mpa.
Waafaqid wanaagsan
ZINDN waxaa loo isticmaali karaa hal lakab ama nidaam laba ama saddex lakab ah oo leh ZD sealer, topcoat, zinc silver, iwm, si loo daboolo baahiyaha macaamiisha ee anticorrosion-ka dheer iyo qurxinta quruxda badan ee xaaladaha deegaanka ee kala duwan.
Ma jiro dildilaac ama dildilaac loo isticmaalo alxanka
ZINDN waxay xallisay cidhiidhiga warshadaha ee lakabka galvanizing si fudud u dildilaaca oo hoos u dhaca bixinta alxanka, hubisa tayada codsiga.
Si fudud loo codsado
Hal baakidh, waxa lagu dabaqi karaa buufin, buraash ama rujin.Ma dego xagga hoose, ma xannibo qoriga, ma xannibo bamka, si habboon loo mariyey.
Qiimaha waxtarka leh
Eco-saaxiibtinimo, qiimo jaban, iyo taabasho sahlan marka la barbar dhigo galvanization-ku-kulul iyo kulaylka.
Mudo dheer oo u dhexeeya taabashada kor iyo dib u soo celinta, qiimo jaban ee ka-hortagga wareegga nolosha marka la barbar dhigo daahanka hodanka ah ee epoxy zinc.
