OEM qaybo bir ah oo saxan saxan sare

Habka daahan ee electrophoretic waa hab daahan isticmaalaya beer koronto dibadda si ay u sameeyaan pigment iyo resin qayb ka xayiran dareere electrophoretic si hab jihada iyo dhigaalka on dusha sare ee substrate ee mid ka mid ah electrodes. Aan eegno habsocodka asaasiga ah ee socodka:

Habka mabda'a

Dahaarka Electrophoretic wuxuu inta badan ku salaysan yahay electrophoresis iyo electrodeposition. Inta lagu guda jiro habka daahan electrophoretic, qayb ka mid ah rinjiga (resin iyo pigments) waxay u dhaqaaqayaan dhanka cathode ka hooseeya falgalka beerta koronto, halka qaybaha xun ee lagu soo oogay u dhaqaaqo dhanka anode ah. Marka qaybaha si togan loo soo dallaco (resin iyo pigments) ay gaadhaan dusha sare ee cathode ( shayga la dahaadhayn doono), waxay helayaan electrons oo ay kaga falceliyaan ions hydroxide si ay u noqdaan walxo aan biyo-milmi karin, kuwaas oo lagu shubo cathode ( shayga la dahaadhaynayo) dahaarka leh) si loo sameeyo filim daahan lebbisan.

Halabuurka habka

Habka daahan electrophoretic guud ahaan ka kooban yahay afar hababka ugu muhiimsan ee soo socda:

1. Pretreatment ka hor daahan: oo ay ku jiraan pre-nadiifinta, xaalufinta, saarista miridhku, dhexdhexaadinta, biyaha dhaqidda, fosfitinta, passivation iyo hababka kale. Nidaamyadan ka-hortagga daaweynta ayaa muhiim u ah tayada iyo waxqabadka dahaarka. Waxay hubiyaan in dusha shayga dahaarka ah uu yahay mid ka madax bannaan saliid iyo miridhku, iyo in filimka fosfasoorku uu yahay mid cufan oo siman ah.
2. daahan Electrophoretic: Ka dib markii pretreatment la dhammeeyo, workpiece la geliyey taangiga electrophoretic iyo daahan electrophoretic waxaa lagu sameeyaa by hadda si toos ah. Nidaamkan, qaybaha rinjiga waxay u guuraan jihada jihada hoos yimaada ficilka beerta korantada waxayna dhigataa dusha sare ee shaqada.
3. Nadiifinta ka dib-electrophoretic: Ka dib markii daahan electrophoretic la dhammeeyo, workpiece u baahan yahay in la nadiifiyo si meesha looga saaro dareeraha taangiga iyo wasakh kale ku lifaaqan dusha. Habka nadiifinta guud ahaan waxaa ka mid ah tillaabooyinka sida nadiifinta taangiga iyo dhaqidda biyaha ultrafiltration.
4. Qalajinta daahan electrophoretic: Ugu dambeyntii, workpiece dahaarka leh daahan electrophoretic waa la qalajiyey si ay u adkeeyaan galay daahan adag. Heerkulka qalajinta iyo wakhtiga waxay ku xiran tahay nooca daahan ee loo isticmaalo iyo shuruudaha shaqada.

Tilmaamaha habraaca

Dahaarku waa mid buuran, labis ah, siman, oo siman, leh sifooyin qurxinta iyo ilaalinta wanaagsan.

Adkeydka dahaarka, adhesion, caabbinta daxalka, waxqabadka saamaynta, iyo waxqabadka dhexgalka ayaa aad uga wanaagsan hababka kale ee daahan.
Isticmaalka rinjiga biyaha ku milma, oo leh biyo sida dhexdhexaadinta dhexdhexaadka ah, waxay badbaadisaa wax badan oo dareeraha organic, waxay yaraynaysaa wasakhowga hawada iyo khataraha deegaanka.
Waxtarka dahaarka ayaa sarreeya, khasaaraha daahan waa yar yahay, iyo heerka isticmaalka daahan wuxuu gaari karaa 90% ~ 95%.

Habka maaraynta cabbirka

Xaaladaha habka daahan electrophoretic waxaa ka mid ah xuduudaha sida halabuurka dareeraha qubeyska, content adag, content ash, MEQ (tirada millimoles ee acid loo baahan yahay halkii 100 garaam ee content adag ee rinjiga) iyo content dareere organic. Maareynta xuduudahan ayaa muhiim ah si loo hubiyo tayada iyo waxqabadka daboolka. Isla mar ahaantaana, sidoo kale waa lagama maarmaan in fiiro gaar ah loo yeesho saameynta arrimaha sida xulashada nidaamka shaandhaynta iyo xajmiga wareegga wareegga ee xasiloonida dareeraha qubayska iyo tayada filimka rinjiga.

Ka taxadaritaan

Inta lagu guda jiro habka daahan electrophoretic, sahayda korontada waa in ay ahaato mid deggan si looga fogaado saamaynta isbedbeddelka danab on tayada daahan.
Si joogto ah u hubi heerka taangiga electrophoretic iyo qalabka si aad u hubiso hawlgalkooda caadiga ah.
Si adag u xakamee xuduudaha habka daahan electrophoretic si loo hubiyo in tayada iyo waxqabadka daahan ay buuxiyaan shuruudaha.
U fiirso hawlgalka badbaadada leh si aad isaga ilaaliso shilalka sida shoogga korantada iyo dabka inta lagu jiro habka dahaarka elektrophoretic.
