Waa maxay hanaannada daweyn ee dusha sare ee lagalaabaayo?

Geedi socodka abuurista lakabka dusha sare ee dusha sare ee maaddada sunta ah ee ka duwan substrates marka loo eego substrate marka loo eego makaanikada, jirka, astaamaha kiimikada waxaa loo yaqaanaa daaweynta dusha sare. Daaweynta dusha sare waxaa loo isticmaalaa in lagu qanco si loo qanciyo faahfaahinta waxyaabaha la mid ah caabbinta saadaasha, xidho iska caabbinta, iyo suuxinta.

Marka lagu daro shuruudaha aasaasiga ah, iska caabbinta hubedda iyo muuqaalka muuqaalka waa in lagu tixgeliyaa inta uu dooran doono boolal. Loogu tala-galayboolal, Nidaamyada Daaweynta Dhulka Sida okce-ka, electrophoresis, korantada elektaroonigga ah, tacromet, iyo kuwa kaleba waxaa badanaa la istcimaalaa.

Marka loo eego midabka dusha sare ee daboolka, waxaa loo qaybin karaa qaybaha soo socda:

Boolal madow oo madow

Madow madowboolalBadanaa ku dar daaweynta madow ee madow, korantada elektaroonigga ah, iyo electrophoresis.

Daaweynta opidation madow

Daaweynta madow ee madow waa hab caan ah oo lagu daaweeyo dusha sare ee kiimikada, ujeedadu waa in la soo saaro filim okside dusha sare si looga fogaado hawada oo looga hortago miridhku.

Hawshu waa in loo isticmaalo si adag oo si adag u ah in lagu xuso dusha sare ee birta si ay u cufto oo sifiican u jilicsan tahay oxide. Lakabkan khafiifka ah ee finanka finanka ah wuxuu si wax ku ool ah u ilaalin karaa gudaha birta ka soo baxa. U qaybsan heerkulka hoose iyo heerkulka sare.

Feroforeric oxide-ka ayaa laga sameeyay heerkul hooseeya (qiyaastii 350 ° C) waa madow madow, oo sidoo kale loo yaqaan madow. Ferrofroferric oxide-ka oo lagu sameeyay oksidation heerkulka sare (qiyaastii 550 ° C) waa cirka buluug, oo sidoo kale loo yaqaan daaweynta qaboojinta. Daaweynta buluugga ah waxaa badanaa loo isticmaalaa wax soo saarka hubka, daaweynta madow waxaa badanaa loo isticmaalaa wax soo saarka warshadaha.

Oxidixixin dusha sare ee birta si ay u cuto cufan, frorobincric jilicsan oxide ayaa u baahan qof xoog badan. Oxidant xoog leh wuxuu ka kooban yahay sodium hydroxide, sodium nitrite, iyo fosfoofka Trisodium. Markay buluug isu rogto, birta ku daadi meel xoog badan oo dhalaalaya, Oo markay madow tahay, oo ay madow ku daad tihiin.

Electroplation

Electroplation-ka waa geedi socodka isticmaalka elektrolysis si loo jaro lakabka filimaan kale oo bir ah ama filimada caadiga ah ee dusha sare ee birta ah. Ujeeddada ayaa ah in la wanaajiyo gashashada caabbinta, iska caabbinta, iyo suuxinta.

Waxaa jira 2 nooc oo ah plaing madow: plags zcl plat iyo nickel madow oo madow.

Boorarka loo yaqaan 'zinc zinc'

Place Pinc Place Places waa nooc ka mid ah kahortaga ka hortagga xudunta ee birta, oo ku habboon badeecada qalabka. Zinc waa mid kiimiko ah oo si fiican u firfircoon oo si sahal ah oo loo yaqaan 'jawiga' jawiga '. Kadib Galvanizing, waxaa lagu daaweeyaa chromate si ay ugu daboosho filim beddelidda kiimikadka ee zinc, si biruhu firfircoon yahay dowlad-ku-meel-gaar ah, oo ah daaweynta wax-ku-xadgudubka ee lakabka zinc. Filimka xaafadaha ayaa loo qaybin karaa cadaan cad (zinc cad), buluug khafiif ah (zinc buluug ah), xaasidnimo madow (zinc madow), naafo cagaaran (zinc cagaaran), iwm.

Badanaa, geedi socodka korantada ee loo yaqaan 'Electroplating' waa nadaafad-nadiifin-nadiifinta-daciif-itching-electro-Galvanizing-nadiifinta-nadiifinta-nadiifinta-nadiifinta-nadiifinta

Black Neckel boorsooyinka loo yaqaan

Caadi ahaan, geedi socodka electropliclical Nikkes madow waa nadaafadda - nadiifinta - firfircoonaanta aashitada ee daciifka ah - nadiifinta - nadaafadda - nadiifinta - nadiifinta - nadiifinta - nadiifinta - rinjiga - rinjiga.

Qeybta Nickel ee madow ee laga helay qubeyska madow ee madow waxaa ku jira 40-60% nikkel, 20-30% zinc, 10-15% baaruud, iyo qiyaastii 10% arrinta dabiiciga ah. Midabka madow waxaa keena joogitaanka nikkel madoow oo ah sulfide madow oo ku taal daboolka oo ay ugu wacan tahay yareynta Thiocyate ee cathode-ka si loo sii daayo ionside. Hoolka kore ee naxaasta ah ayaa lagu soo daray hawsha, howsha ugu weynna waa in la saadaalinayo Nickel sahlan ee habka boostada iyo in la wanaajiyo iska caabbinta isku-darka ee daboolka.

Electrophoresis

Electrophoresis waxaa loola jeedaa ifafaale ee ku xusan walxaha lagu soo eedeeyay inay u dhaqaaqdo elektaroonigga ah ee elektaroonigga ah ee guryaha korantada ka soo horjeedda ee ku xusan ficilka duurka.

Electrophoresis madow waa adeegsiga beer-korantada dibedda si loo sameeyo walxaha sida midabka midabka iyo ress lagu hakiyey xalka korantada ee elektrophoressis jie-u-higsan oo ku yaal dusha sare ee elektaroonigga ah. Madowga elektrophorotic-ga ayaa si weyn loogu isticmaalaa warshadaha, qaadashada habka madow ee tusaale ahaan: nabaad-guurinta - nadiifinta - posphophating - rinjiga elektaroonigga ah - qalajinta. Waxaa loo qeybin karaa electrophoresis-ka cudurka atodic (resin wuxuu noqon karaa ionsic ka dib markii la kariyo ee ionization) iyo cathodic electrophoresis (resin wuxuu noqdaa ion toon ka dib markii electrophoresis). Marka la barbar dhigo nidaamka rinjiga, waxay leedahay wax qabad dhismeed oo ka yar, wasakhda iyo waxyeelo jawiga iyo iska caabinta buufinta milixda ee dhexdhexaadnimada ah waa 300 saacadood, iyo caabbinta iyo iska caabbinta-goynta ayaa la mid ah kuwa habka loo yaqaan 'Discotion'.

Boolal cad oo cad

Boorarka cad ee caanka ah badiyaa waxaa ka mid ah elektaroonigga cad, zinc cad, iyo wixii la mid ah.

Electroplating zinc cad

Casharka zinc cad

Geedi socodka korantada zinc cad waa nasiino-nadaafad-nadiifin-daciif ah-Galvanizizing-nadiifiye-nadiifin-nadiifin-nadiifinta. Farqiga uga yimaada zinc madow ayaa ah in aysan jirin rinji aan xad dhaaf ahayn, xalka xaasigana wuu ka duwan yahay. Gurida cad-cad waa filim midab la'aan oo midab leh oo ay ka kooban tahay komic-ga, sidaa darteed iska caabbinta hudheelka ayaa ka liidata kan zinc madow, zinc buluug ah, iyo zinc zinc-ka buluug ah.

Iidhiidha iska caabbinta zinc cad ayaa ka fiican kan cadaanka cad, muuqaalkiisana wuu ka madoobaaday kan nikkel cad.

Electroplication elect nikkel cad

Nabarrada loo yaqaan 'cad'.

Geedi socodka ku saabsan elektaroonigga elektaroonigga ah ee nikkel cad waa nadaafadda - nadiifinta - firfircoonaanta aashitada daciifka ah - nadiifinta - nadaafadda hoose - nadiifinta - nadiifinta - nadiifinta - qalajinta - ama xiridda - ama xirashada. Geedi socodka korantada elektaroonigga ah ee nikkel cad iyo elektaroonigga ah ee elektaroonigga ah oo asal ahaan waa isku mid, farqiga u dhexeeya qaaciddada xalka korantada ee xalka korantada, iyada oo aan lagu darin zinc suldide.

Midab kale oo loo yaqaan ''

Midabka boorarka la qoray

Goynta midabada kale badiyaa waxaa ku jira buluug zinc buluug ah, cagaaran zinc, zinc midab leh, iyo dacromet.

Habka korantada ee elektaroonigga ah ee zinc buluug iyo zinc cagaaran waxay la mid tahay kuwa zinc cad. Zinc zinc zinc waa filim zinc ah oo la soo rogay oo ay kujiraan 0.5-0.6 mg / dm2 ee chromium-ka xaraashka ah. Fasalka cagaaran waxaa sabab u ah xaqiiqda ah in xalka xaafadaha uu ka kooban yahay fosphate ion, iyo filimka cagaaran ee ka dhalanaya ay ka kooban yihiin chromate iyo fosfooras.

Iidhiidhada hufnaanta ee zinc buluug ah ayaa ka fiican kan zinc cad, iyo iska caabbinta jiifka ee zinc cagaaran ayaa ka fiican kan zech buluug ah.

Zinc midabku wuxuu leeyahay iska caabbinta hufnaanta. Geedi socodka xaadirka ah waa: Nadiifinta - Nadiifinta - 2% -3% nitric acid si aad u iftiimiso - nadaafadda 'ka dhigista midabaynta' chromium '- nadiifinta Heerkul aad u hooseeya inta lagu gudajiro inta lagu gudajiro waxay ku dambayn doontaa in filim filim tartiib tartiib ah iyo filim khafiif ah. Heerkulka sare wuxuu sababi doonaa filimka inuu noqdo mid qaro weyn oo dabacsan, cunistaduna xoog ma yeelan doonto. Waxaa ugufiican in la xakameeyo qiyaastii 25 digrii si loo hubiyo inaad isku midab tahay waqti cayiman. Kadib, waxay u baahan tahay in la dubo si loo wanaajiyo adhesion iyo iska caabbinta isku-darka filimka.

Dacromet

Dacromet waa nooc cusub oo kahortaga ka hortagga dabada leh ee leh budada zinc, budada aluminimka, chromic acid, iyo biyo-u-dhimin biyo ahaan qaybaha ugu muhiimsan. Qulqulka geeddi-socodka ayaa ah mid tacliinta dabiiciga ah - farsamada farsamada - profilation - buufin - dubista labaad - qalajinta - qalajinta.

Faa'iidada geedi socodka Dacromet ayaa ah in iska caabbinta la isku dayo uu aad u wanaagsan yahay, laakiin baahida darrooyinka ayaa ah in daaha uusan labis ahayn.
