Waa maxay faraqa u dhexeeya xaashida galvanized iyo xaashida birta ah

Xaashiyaha galvanized waxaa loola jeedaa saxan bir qaro weyn leh oo lakabka zinc ku dahaadhay dusha sare.Galvanization-ku-kulul waa hab daaweyn dhaqaale oo macquul ah oo ka-hortagga miridhku kaas oo inta badan la doorto.Qiyaastii kala badh wax soo saarka zinc ee adduunka ayaa loo isticmaalaa habkan.
Xaashiyaha galvanized waa in laga fogaado daxalka dusha sare ee saxanka qaro weyn oo ay kordhiso nolosheeda adeeg.Dusha sare ee saxan birta qaro weyn ayaa lagu dahaadhay lakabka zinc birta ah.Noocaan saxan bir qaro leh oo zinc-dahaarka leh waxaa loo yaqaan xaashi galvanized.
Marka loo eego hababka wax soo saarka iyo habaynta, waxa loo qaybin karaa qaybaha soo socda:
① Saxan bir qaro weyn leh galvanized kulul.Waraaqda birta ah ee qabow-duuban waxaa lagu dhex daraa qubeyska zinc ee dhalaalaysa, si dusha sare ee xaashida birta qabow lagu dhejiyo lakabka zinc.Marxaladdan, furaha ayaa ah in la isticmaalo habka kululaynta kulul ee joogtada ah ee wax soo saarka, taas oo ah, saxan qaro weyn oo saxan ah ayaa si joogto ah loogu dhex daraa haanta dahaadhka leh ee zinc la dhalaaliyay si loo sameeyo xaashi galvanized;
②Saraashka galvanized ee lagu xoojiyay hadhuudh-fiican.Noocaan saxan bir ah oo qaro weyn ayaa sidoo kale lagu soo saaraa habka kuleylka kulul, laakiin isla markiiba ka dib marka ay ka baxdo taangiga, waxaa lagu kululeeyaa ilaa 500 ° C si loogu beddelo aluminium caag ah oo caag ah oo zinc iyo birta ah.Noocaan xaashida galvanized wuxuu leeyahay dhejis heer sare ah oo ah dahaarka dhismaha iyo alxanka korantada;
③ xaashi koronto galvanized ah.Soo saarista xaashida galvanized ee noocan oo kale ah ee loo yaqaan 'electroplating' waxay leedahay waxqabadka habraaca wanaagsan.Si kastaba ha ahaatee, dahaarka waa dhuuban, iyo iska caabin daxalka uma fiicna sida xaashi galvanized kulul-muquufin;
④ Xaashiyaha galvanized-ka ah iyo laba-geesoodka ah.xaashi keli ah iyo laba-geesood ah oo galvanized ah, taas oo ah, alaabada galvanized-kulul laga sameeyay hal dhinac oo kaliya.Marka la eego alxanka korantada, buufinta, daaweynta ka hortagga miridhku, wax soo saarka iyo habaynta, iwm, waxay leedahay la qabsi ka xoog badan xaashida galvanized laba-geesoodka ah.Si looga takhaluso cilladda zinc aan la daboolin ee labada dhinacba, waxaa jira nooc kale oo xaashida galvanized ah oo lagu daboolay zinc chromatographic dhinaca kale, taas oo ah, xaashi galvanized oo leh farqi labada dhinac ah;
⑤ aluminium alloy, xaashi galvanized ah oo isku dhafan.Waxay ka samaysan tahay zinc iyo walxo kale oo bir ah sida aluminium, lead, zinc, iwm.Nooca noocan ah ee saxan bir qaro weyn ayaa leh labadaba sifooyin daaweyneed oo aan caadi ahayn oo ka hortagga miridhku iyo sifooyin buufin oo aad u fiican;
Marka laga soo tago shanta sare, waxa kale oo jira xaashi galvanized midab leh, daabacaadda dharka lagu buufiyo xaashida galvanized, xaashida galvanized polyetylen laminated iyo wixii la mid ah.Laakiin marxaladan, tan ugu caansan ayaa weli ah xaashi galvanized kulul.
Saxanka birta ah waa magaca guud ee birta u adkaysata aashitada, u adkaysata walxaha daciifka ah sida gaaska, uumiga, biyaha, ama darajooyinka birta leh sifooyinka birta aan fiicnayn waxaa lagu magacaabaa saxan bir ah;halka walxaha u adkaysta dareeraha (asiidhka, alkali, milixda iyo daxalka kiimikooyinka kale ee dabiiciga ah) ) Heerarka birta la jeexjeexay waxaa loo yaqaannaa birta u adkaysata aashitada.
Sababtoo ah kala duwanaanshaha halabuurka labada, iska caabbinta daxalka ayaa ka duwan.Guud ahaan, taarikada birta-la'aanta ah guud ahaan uma adkeysaneyso daxalka dareeraha ah, halka birta u adkeysata aashitada ay guud ahaan leeyihiin sifooyin bir ah.Erayga "saxadiga birta ah ee birta ah" kaliya maahan mid si fudud loola jeedo nooc ka mid ah saxan birta ah, laakiin sidoo kale wuxuu muujinayaa in ka badan 100 nooc oo ah taargooyinka birta ah ee warshadaysan.Mid kasta oo saxan bir ah oo la sameeyay oo nashqadeeyay waxay yeelan doontaa sifooyin aad u wanaagsan ujeeddadeeda ugu weyn.Furaha guusha waa in la ogaado isticmaalka aasaasiga ah marka hore, ka dibna darajada birta ee habboon.Guud ahaan waxa jira lix darajooyin bir ah oo la xidhiidha ujeedada ugu weyn ee dhismaha.Dhammaantood waxay leeyihiin 17-22% chromium, iyo darajooyinka birta wanaagsan waxay kaloo leeyihiin nikkel.Ku darida molybdenum waxay sii wanaajisaa daxalka hawada waxayna aad u adkaysataa hawada ay ku jirto fluoride.
Saxanka birta ah waxaa loola jeedaa birta u adkeysata walxaha daciifka ah sida gaaska, uumiga, biyaha, iyo walxo kiimiko ah oo dabiici ah sida aashitada, alkali, iyo cusbada, oo sidoo kale loo yaqaano birta u adkaysata aashitada.Codsiyada gaarka ah, birta u adkaysata walxaha daciifka ah ee daciifka ah waxaa badanaa loo yaqaannaa birta, iyo birta u adkaysata daxalka dareeraha waxaa loo yaqaannaa birta u adkaysata aashitada.Sababtoo ah farqiga u dhexeeya halabuurka u dhexeeya labada, hore maahan mid u adkaysata daxalka dareeraha, halka kan dambe uu guud ahaan yahay mid aan nadiif ahayn.Iska caabbinta daxalka ee taarikada birta ah ee birta ah waxay ku jirtaa walxaha aluminium aluminium ee ku jira birta.
