Guryaha Makaanikada:
• Duplex Stainless Steels waxay leeyihiin qiyaas ahaan laba jibaar xoogga wax soo saarka ee buundooyinka austenitic dhiggooda ah.
Tani waxay u oggolaanaysaa naqshadeeyayaasha qalabka inay u isticmaalaan qalab khafiif ah oo lagu dhisayo markabka!
Faa'iidada birta aan lahayn Duplex:
1. Marka la barbar dhigo austenitic ahama
1) Xoogga wax-soo-saarku wuxuu ka badan yahay laba jeer ka sarreeya kan caadiga ah ee austenitic ahama, wuxuuna leeyahay caag adag oo ku filan oo loo baahan yahay qaabeynta. Dhumucda taangiga ama weelka cadaadiska ee ka samaysan birta laba-laabka ah ayaa 30-50% ka hooseeya tan caadi ahaan loo isticmaalo birta austenitic, taas oo faa'iido u leh in la yareeyo kharashka.
2) Waxay leedahay iska caabin heer sare ah si ay u dillaacdo daxalka stress, gaar ahaan deegaanka ka kooban chloride ions, xitaa daawaha duplex leh content alloy ugu hooseeya ayaa iska caabin sare u adkaysta daxalka dillaacsan badan austenitic ahama. Daxalka Cadaadisku waa dhibaato caan ah oo birta austenitic-ka caadiga ah ay adagtahay in la xalliyo.
3) Inta ugu badan ee 2205 birta duplex birta ah ee loo isticmaalo warbaahinta badan ayaa iska caabin wanaagsan ka leh birta 316L austenitic birta caadiga ah, halka super duplex birta aan daxalka lahayn ay leedahay iska caabin daxalka sare leh. Warbaahinta qaarkood, sida acetic acid iyo formic acid. Waxay xitaa bedeli kartaa birta aan lahayn austenitic alloy-sare iyo xitaa daxalka u adkaysta.
4) Waxay leedahay iska caabin wanaagsan oo ku saabsan daxalka maxalliga ah. Marka la barbar dhigo birta austenitic ahama oo leh isla maadada aluminiumka, waxay leedahay iska caabin wanaagsan oo iska caabin ah iyo iska caabin daxalka daxalka ah marka loo eego birta birta ah ee austenitic.
5) Birta aan lahayn austenitic waxay leedahay isugeyn hoose oo balaadhinta toosan waxayna ku dhowdahay birta kaarboonka. Waxay ku habboon tahay isku xirka birta kaarboon waxayna leedahay muhiimada injineernimada, sida soo saarista taarikada ama dahaarka.
2. Marka la barbar dhigo birta aan birta lahayn ee ferritic, faa'iidooyinka birta aan duplex-ka lahayn waa sida soo socota:
1) Qalabka farsamada ee dhameystiran ayaa ka sarreeya kan birta birta ah ee ferritic, gaar ahaan adagaanta caaga ah. Uma dareensiino jajabnaanta sida birta aan lahayn ee ferritic.
2) Marka lagu daro iska caabbinta daxalka cadaadiska, iska caabbinta daxalka kale ee maxalliga ah ayaa ka sarreeya birta daxalka ee ferritic.
3) Waxqabadka habka shaqada qabow iyo samaynta qabowga ayaa aad uga fiican birta birta ah ee ferritic.
4) Waxqabadka alxanka ayaa aad uga wanaagsan kan birta aan lahayn ferritic. Guud ahaan, daawaynta kulaylka looma baahna ka dib kulaylka ka dib alxan la'aan.
5) Kala duwanaanshaha codsigu wuu ka ballaaran yahay kan birta aan lahayn ferritic.
CodsigaSababtoo ah xoogga sare ee birta labajibbaaran, waxay u egtahay inay kaydiso walxaha, sida yaraynta dhumucda gidaarka ee tuubada. Isticmaalka SAF2205 iyo SAF2507W tusaale ahaan. SAF2205 waxay ku haboon tahay in lagu isticmaalo deegaan ay ku jirto koloriin waxayna ku haboon tahay in lagu isticmaalo warshadaynta ama habka kale ee warbaahinta lagu qasay koloriin. SAF 2205 waxay si gaar ah ugu habboon tahay isticmaalka kulaylka beddelayaasha ay ku jiraan koloriin aqueous ama biyo jilicsan sida dhexdhexaadinta qaboojinta. Maaddadu waxay sidoo kale ku habboon tahay in lagu milo xalalka sulfuric acid iyo acids organic saafi ah iyo isku-darkooda. Sida: dhuumaha saliida ee warshadaha saliida iyo gaaska: nadiifinta saliida cayriin ee sifaynta, nadiifinta gaasaska ku jira baaruudka, qalabka daaweynta biyaha wasakhda; hababka qaboojinta iyadoo la isticmaalayo biyo jilicsan ama xalalka koloriin ku jira.
