Kala soocida hababka dahaadhsan ee chrome-ka ee tuubooyinka birta ah ee chrome plated

Tuubooyinka birta ah ee dahaadhka ah ee Chromewaxaa lagu dahaadhay lakabka birta ah ee dusha sare ee birta birta ee birta iyada oo loo marayo koronto-siin.Ujeedada ugu muhiimsan ee tuubooyinka birta ee chromium-ka ah waa ilaalinta.Tuubooyinka birta dahaadhka leh ee Chromium waxay leeyihiin degganaansho kiimiko oo wanaagsan oo kama falceliyaan alkali, sulfides, nitric acid, iyo inta badan asiidhyada organic.Tuubooyinka birta dahaadhka leh ee Chromium waxay ku milmi karaan acid hydrochloride (sida hydrochloride acid) iyo sulfuric acid kulul.Marka labaad, dahaadhaynta chromium waxay leedahay iska caabin kulayl oo wanaagsan, iyo tuubooyinka birta ee chromium-ka dahaadhay oo kaliya oxide iyo midab marka heerkulku ka weyn yahay 500 darajo Celsius.Waxaa intaa dheer, isugeyntiisa isku dhafka ah, gaar ahaan isku-dhafka qallalan ee qallalan, ayaa ah kan ugu hooseeya dhammaan biraha, iyo tuubooyinka birta ah ee chrome waxay leeyihiin iska caabin heer sare ah.Qiyaasta iftiinka muuqda, awoodda milicsiga ee chromium waxay ku dhowdahay 65%, inta u dhaxaysa qalin (88%) iyo nikkel (55%).Chromium ma beddelo midabka, iyo tuubooyinka birta ah ee chrome waxay sii wadi karaan awooddooda milicsiga muddo dheer marka la isticmaalo, taas oo ka fiican qalin iyo nikkel.Waxaa jira saddex nooc oo ah hababka dahaadhka chrome.

1. Ilaalinta - Ilaalinta Daabacaadda Chromium ee Qurxinta - Qurxinta Chromium Plating, oo loo yaqaan 'Decorative Chromium', waxay leedahay daahan dhuuban oo dhalaalaya oo inta badan loo isticmaalo lakabka sare ee koronto-lakabyada badan.Si loo gaaro ujeedooyinka ilaalinta, lakab dhexdhexaad ah oo ku filan waa in marka hore lagu dhejiyaa zinc ku salaysan ama substrate bir ah, ka dibna lakab dhexdhexaad ah oo dhalaalaya 0.25-0.5 waa in lagu dhejiyaa korkiisa μ Lakabka khafiifka ah ee chromium ee m.Habka caadiga ah ee la isticmaalo waxaa ka mid ah Cu/Ni/Cr, Ni/Cu/Ni/Cr, Cu Sn/Cr, iwmMa beddelo midabka ka dib soo-gaadhista muddada dheer ee jawiga.Noocan dahaarka ah ayaa si weyn loogu isticmaalaa ilaalinta iyo qurxinta qaybaha sida baabuurta, baaskiiladaha, mashiinnada dharka, saacadaha, qalabka, iyo qalabka maalinlaha ah.Lakabka chromium ee wax lagu qurxiyo ee la qurxiyey ayaa leh awood sare oo iftiin leh waxaana loo isticmaali karaa muraayad ahaan.Daloolada yaryar ama microcracks of chromium on nikkel lakabka badan waa hab muhiim ah si loo yareeyo wadarta dhumucda dahaarka iyo helitaanka nidaamka qurxinta leh ilaalinta daxalka sare.Sidoo kale waa jihada horumarinta hababka elektiroonigga ah ee casriga ah.
2. Chromium adag (chromium-u adkaysta xidhashada) dahaadhay waxay leedahay adkeysi aad u sarreeya oo xidho iska caabin ah, kaas oo kordhin kara nolosha adeegga ee workpieces, sida jarida iyo qalabaynta, riixaya iyo tuurista caaryada ee alaabta kala duwan, biraha, ulaha, cabbirada, marsho. iwm, iyo sidoo kale waxaa loo isticmaali karaa in lagu hagaajiyo dulqaadka cabbirka qaybaha xiran.Dhumucda lakabka chromium adag guud ahaan waa 5-50 μm.Waxa kale oo lagu go'aamin karaa iyada oo loo eegayo baahiyaha, qaar ka mid ah ilaa 200-800 μ M. Chromium adag oo ku dahaadhay qaybaha birta uma baahna daahan dhexdhexaad ah.Haddii ay jiraan shuruudo gaar ah oo loogu talagalay iska caabinta daxalka, dahaarka dhexdhexaadka ah ee kala duwan ayaa sidoo kale la isticmaali karaa.
3. Lakabka cad ee chromium plating waa caano cad, oo leh dhalaal hooseeya, adayg wanaagsan, borosity hooseeya, iyo midab jilicsan.Adaggeedu wuu ka hooseeyaa kan chromium-ada adag iyo chromium-ka la isku qurxiyo, laakiin waxa uu leeyahay iska caabin daxaleed oo sarreeya, sidaas awgeed waxa caadi ahaan loo adeegsadaa qalabka cabbiraadda iyo muraayadaha qalabka.Si loo hagaajiyo adkaantiisa, lakabka chromium adag, oo sidoo kale loo yaqaan daahan labajibbaaran ee chromium, ayaa lagu dahaadhi karaa dusha sare ee daahan cad caanaha, kaas oo isku daraya sifooyinka labada lakab ee chromium cad caanaha iyo daahan adag ee chromium.Waxaa badanaa loo isticmaalaa qaybaha daahan ee u baahan labadaba caabbinta xirashada iyo iska caabinta daxalka.
4. Daabacaadda chromium dalool (chromium dalool) waxay isticmaashaa sifooyinka dildilaaca chromium laftiisa.Ka dib marka la dhejiyo chromium adag, makaanik, kiimiko, ama daawaynta porosity elektrokimika ayaa la sameeyaa si loo sii qoto dheereeyo oo loo ballaariyo shabakadda dillaaca.Dusha sare ee lakabka chromium waxaa lagu daboolay jeexdin ballaaran, taas oo aan kaliya waxa uu leeyahay sifooyinka chromium xidho u adkaysta, laakiin sidoo kale si wax ku ool ah u kaydiyaa warbaahinta saliidayn, ka hortagtaa hawlgalka non saliidayn, iyo hagaajinaysaa khilaaf iyo xidho iska caabin ah oogada workpiece ah.Inta badan waxaa loo isticmaalaa in lagu dahaadhiyo dusha sare ee qaybaha is jiid jiidka simbiriirixidda ee cadaadis culus, sida qolka gudaha ee foosto dhululubo dabka gudaha ah, giraanta piston, iwm.
⑤ Dahaarka madow ee chromium-ka madow ee koromiumku waxa uu leeyahay dhalaal isku mid ah, qurxin wanaagsan, iyo dabar-goyn wanaagsan;Adaggu waa mid aad u sarreeya (130-350HV), caabbinta xirashaduna waa 2-3 jeer ka sarreeya tan nikkel dhalaalaya oo isku mid ah oo dhumucdiisuna tahay;Iska caabbinta daxalka waxay la mid tahay dahaadhka chromium ee caadiga ah, badiyaa waxay ku xidhan tahay dhumucda lakabka dhexe.U adkaysiga kulaylka wanaagsan, ma jiro midab ka hooseeya 300 ℃.Lakabka chromium-ka madow waxaa si toos ah loogu dahaaran karaa dusha sare ee birta, naxaasta, nikkelka, iyo birta aan lahayn.Si loo hagaajiyo caabbinta daxalka iyo saamaynta qurxinta, naxaasta, nikkel, ama daasadda naxaasta ah ayaa sidoo kale loo isticmaali karaa lakabka hoose, iyo daahan madow ee chromium ayaa lagu dhejin karaa dusha sare.Daahan madow ee chromium waxaa caadi ahaan loo isticmaalaa in lagu dahaadho ilaalinta iyo qurxinta qaybo ka mid ah qalabka duulista iyo aaladaha indhaha, muraayadaha nuugista tamarta qorraxda iyo baahiyaha maalinlaha ah.
