Daaweynta dusha sare

Ugu horreyntii, waxaan u baahannahay inaan ogaano sababta ay badeecaddu ugu baahan tahay daaweynta dusha sare, maxay tahay shaqada, iyo dhibaatada ay xalliso.

Ugu horreyntii, habka daaweynta dusha sare ee si dabiici ah loo sameeyo lakab dusha sare ah oo ka mid ah maaddada substrate-ka oo ka duwan farsamooyinka, muuqaalka jirka iyo kiimikada alaab-dhismeedka. Ujeedada daaweynta dusha sare waa in lala kulmo caabbinta daxalka ee badeecada, xirashada caabbinta, qurxinta ama shuruudaha kale ee shaqeynta gaarka ah.

Macaamiil badan ayaa na weydiin doona sababta aan ugu baahan nahay daaweynta dusha sare, maxay tahay shaqada, maxaase ugu wacan in lagu daro howshan?

Shaqaalaha farsamada Ouzhan:Daaweynta dusha sare waa in laga saaro dhammaan noocyada ajaanibta ah (sida saliidda, miridhku, boodhka, filimka ranjiga duugga ah, iwm) ee ku dheggan dusha sare ee shayga, oo la siiyo substrate wanaagsan oo ku habboon shuruudaha dahaadhka si loo hubiyo in filimka dahaadhka wuxuu leeyahay difaac wanaagsan. Waxqabadka daxalka, waxqabadka qurxinta iyo qaar ka mid ah shaqooyinka gaarka ah, dusha sare ee shayga waa in la sii daayo kahor rinjiyeynta. Shaqada ay qabato daaweynta noocan ah waxaa si wada jir ah loogu magacaabaa daaweyn hore (dusha) daaweynta ama (dusha) daaweynta.

Daaweynta dusha sare waxay sare u qaadaa adkeysiga iyo adkeysiga abrasion ee sheyga. Asalka asalka ah, waxay kordhisaa waqtiga isticmaalka waxayna keydineysaa waqti badan, kharash iyo lacag.

Habka koronto

Habkani wuxuu adeegsadaa falcelinta koronto si uu u sameeyo daahan dusha sare ee qalabka shaqada. Hababka ugu muhiimsan waa:

(2) Dahaadhka koronto la'aanta

Xalka elektaroolka, dusha sare ee qalabka shaqada si dabiici ah ayaa loo daaweeyaa iyada oo aan wax saameyn ah ku yeelanayn duruufaha dibadda. Xalka, sababtoo ah yaraynta walxaha kiimikada, habka dhigaalka walxaha qaarkood dusha sare ee qeybta shaqada si loo sameeyo daahan waxaa loo yaqaanaa dahaadhka koronto la'aanta, sida nikkel bilaa elektarooniga ah, Korantada naxaasta ee koronto la'aanta, iwm.

QALABKA QALABKA kululaynta

Habkani waa in lagu dhalaaliyo ama heerkul ahaan lagu kala faafiyo waxyaabaha ku jira xaaladaha heerkulka sare si loo sameeyo daahan dusha sare ee goobta shaqada. Hababka ugu muhiimsan waa:

(1) Dareemo kulul

Habka loo gelinayo biraha la shubay si loo sameeyo daahan dusha sare waxaa loo yaqaan 'hot-dip plating,' sida galvanized kulul iyo aluminium kulul.

(2) Ku buufin kuleylka
Nidaamka atomiska birta la shubay oo lagu buufinayo dusha sare ee goobta shaqada si loo sameeyo daahan waxaa loo yaqaan ku xereen kuleylka, sida zinc ku buufinta kuleylka iyo aluminium ku buufinta kuleylka.

SHAQAALAHA FARSAMADA

1. Electrophoresis

Sida koronto ahaan, qeybta shaqada waxaa lagu shubayaa rinjiga biyaha lagu shubo ama biyaha lagu shubo, wuxuuna ku sameeyaa wareeg koronto kale rinjiga. Marka la eego ficilka aagga korantada, xalka daahan ayaa loo kala saaray ion cusbi oo la soo oogay, cations-gu wuxuu u wareegayaa cathode, anions-na waxay u guureen anode. Kuwani ion cusbi la soo eedeeyay, oo ay la socdaan qayb ka midabka midab adsorbed, waxaa electrophoresed dusha sare ee workpiece ah si ay u sameeyaan daahan a. Nidaamkan waxaa lagu magacaabaa electrophoresis.

2. Xereen Electrostatic

Marka la eego ficilka korantada korantada sare ee DC, walxaha rinjiga ee si otomaatig ah loogu soo oogay rinjiga waxaa lagu jiheeyaa inay u duulaan goobta shaqada oo si wanaagsan loogu soo oogay si ay u helaan filim rinji ah, oo loo yaqaan buufin joogto ah.
