Daawaynta ka hor iyo habka korantada

Sharaxaad Gaaban:

Dahaarka pretreatment waa diyaarinta dusha daahan ka hor daahan oo waa saldhigga habka daahan oo dhan.
Tayada pretreatment waxay si toos ah u saameeyaa tayada daahan oo dhan, sidaas darteed waa in aan fiiro gaar ah u.


Sharaxaada Alaabta

Qalab kala duwan iyo alaabooyinkooda habka farsamaynta, gaadiidka, kaydinta, dusha sare waa sahlan tahay in la soo saaro ama
ku dheji walxaha shisheeye, sida mashiinka mashiinka, maqaarka oksaydhka, saliidda, iwm., wasakhooyinka dusha sare waxay saameyn doonaan cufnaanta dahaarka iyo xoogga isku xirnaanta ee matrixka.Dahaarka pretreatment ee ugu muhiimsan Ujeeddada waa in laga saaro walxahan iyo in la sameeyo beddelka kiimikada dusha ku habboon si ay u bixiyaan shuruudahaCoating ku habboon ee substrate ah, si loo kordhiyo adhesion ee filimka, dheereeyo nolosha adeegga filimka, Siiso ciyaar buuxda si ay u difaaca. saamaynta iyo saamaynta qurxinta ee daahan.

Sidaa darteed, buufin waxa ku jira ka hor farsamaynta.Inta badan waxa ka mid ah dhinacyada soo socda:

Hoosudhaca ka hor daahan

Birta iyo qaybo ka mid ah habka kaydinta iyo gaadiidka si ay u isticmaalaan ilaalinta saliid antirust, sheet birta workpiece ee saliid sawiro waa in la isticmaalaa marka processing cadaadiska, qaybaha waa in ay la xiriiraan emulsion marka machining, daaweynta kulaylka laga yaabaa in ay la xiriirto saliid qaboojinta, marka qaybo ka mid ah inta badan saliid wasakhda iyo HanJi ee gacmaha hawlwadeenka, dufanka qaybaha laakiin sidoo kale wasakhda sida had iyo jeer iyo boodhka isku qasan Dhammaan waxyaalahan oo dhan, dhammaan noocyada saliidda ee qaybaha ma aha oo kaliya inay carqaladeeyaan samaynta filimka fosfatka, laakiin sidoo kale waxay saameeyaan adhesion ee daahan waxqabadka qalajinta qurxinta waxqabadka iyo iska caabinta daxalka Shaxda 3-1 ayaa taxaysa pretreatment kala duwan ee saxan bir duuban qabow.Saamaynta daahan kathodic electrophoretic on caabbinta daxalka.

Fosfatinta

Phosphating waa hab fudud, la isku halayn karo, qiimo jaban oo ku habboon si aad u wanaajiso caabbinta daxalka ee daahan birta ah.Waxaa si weyn looga isticmaali jiray gudaha iyo dibadda, gaar ahaan dahaadhka baabuurta, kaas oo aad loo isticmaali jiray sannadihii u dambeeyay.Ku dhawaad ​​100% qaybaha saxan khafiifka ah ee warshadaha baabuurta waa fosfat habka Phosphating waxaa loola jeedaa dusha birta ee xiriir la xal acid ka kooban dihydrogen fosfate cusbada, falcelinta kiimikaad iyo soo saaray ee xasiloonida dusha birta ee lakabka xuub unug aan la milmayn Habka daaweynta kiimikaad ee dusha sare iyo filimka la soo saaray ee loo yaqaan 'phosphating film'.

Mabda'a filimka 'phosphate'

filimka phosphating wuxuu awooday inuu bixiyo saldhig aad u habboon oo loogu talagalay daaha rinjiga, waxaa sabab u ah saameynta soo socota:
1) Waxay siisaa nadiif, lebis, oogada dufanka la'aan ah iyada oo ku saleysan xaalufinta dhammaystiran
2) waxay wanaajisaa adhesion of film organic in substrate ay sabab u tahay ficil jirka iyo kiimikaad Ma aha wax adag in la fahmo in qaab-dhismeedka dalool ee filimka fosfooraska kordhiyaa aagga dusha sare ee substrate ah, si meesha xidhiidhka ka dhexeeya labada kordho u dhigma, iyo faa'iidada wadaagga ah ee faa'iidada leh ee u dhexeeya labada lakab ee filimka ayaa la soo saaray.Isla mar ahaantaana, isdhexgalka kiimikaad ee u dhexeeya resin aan saturated iyo crystal phosphate waxay sidoo kale kor u qaadaysaa xooggeeda xidhitaanka
3) waxay bixiyaan lakab go'doon ah oo xasilloon oo aan fiicneyn, hal mar dhaawaca daahan, waxay leedahay doorka xakamaynta daxalka, gaar ahaan jeexitaanka anode Qodobka ugu horreeya ayaa badanaa la dayacay Kaliya si buuxda ugu fiican saliidda si loo sameeyo filim fosfit ah oo ku qanacsan sidaas darteed. Filimka fosfatka laftiisa ayaa ah saameynta ugu dareensan ee tignoolajiyada pretreatment ee ugu kalsoonida badan ee is-hubinta.
