Daawaynta dusha sare ee Birta MIM

Soo koobidQaybaha Birta MIMHabka Wax-soo-saarka iyo Codsiga

Thewax soo saarka MIMhabka guud ahaan waxaa ka mid ah: isku dhafka iyo granulation, qaabeynta duritaanka, hoos u dhigista, sintering, iyo habaynta sare.
(1) Tilmaamaha Farsamada ugu muhiimsan ee qaybaha Birta MIM:

• 1. Waxay ku habboon tahay samaynta qalabyo kala duwan oo budo ah, badeecaduna si ballaaran ayaa loo isticmaalaa;
• 2. Heerka isticmaalka sare ee alaabta ceeriin iyo heerka sare ee wax soo saarka otomatiga, oo ku habboon wax soo saarka ballaaran ee joogtada ah.
• 3. Waxay si toos ah u samayn kartaa qaybo yaryar oo leh qaabab joomatari oo adag (0.03g ~ 200g);
• 4. Saxnaanta cabbirka qaybuhu waa sarreeyaa (± 0.1%～± 0.5%), iyo dhamaystirka dusha sare waa mid wanaagsan (qallafsanaanta 1～5μm);
• 5. Alaabtu waxay leedahay cufnaanta qaraabada sare (95-100%), urur labis ah iyo waxqabad aad u fiican;

Dhowr hab oo daawaynta dusha sare ah oo caadi ahaan loo isticmaalo qaybaha Birta MIM

La tolay
Isticmaalka farsamada, kiimikaad ama fal elektaroonig ah, qallafsanaanta dusha sare ee shaqada waa la dhimay si loo helo dusha dhalaalaya oo siman.

Korantada
Habka lagu dhejiyo filimka birta ah ee dusha sare ee birta ama walxo kale by electrolysis. Electroplating waxay ka hortagi kartaa oksaydhka birta (sida miridhku), waxay wanaajisaa iska caabbinta xidhashada, korantada korantada, milicsiga, iska caabinta daxalka (sulfate copper, iwm.) waxayna wanaajisaa bilicda.

Daaweynta PVD
Isticmaalka hababka jireed si loo gaaro wareejinta ballaaran, habka wareejinta atamka ama molecules-ka isha ilaa dusha sare ee substrate-ka. Shaqadeedu waa in lagu buufiyo qaybo gaar ah oo leh awood sare oo gaar ah, xirto caabbinta, kuleylka kuleylka, iska caabinta daxalka, iwm.) Matrixka oo leh waxqabad hoose, si uu matrixku u yeesho waxqabad wanaagsan.

Madaw
Waa habka daaweynta kiimikada caadiga ah si loo soo saaro filim oksaydh ah oogada birta ah si loo go'doomiyo hawada loona gaaro ujeedada ka hortagga miridhku. Marka shuruudaha muuqaalka aan sare loo qaadin, daaweynta madow ayaa la isticmaali karaa. Qaybaha ugu muhiimsan ee dareeraha madowga ah waa sodium hydroxide iyo sodium nitrite.

Fosfatinta

Waa habka falcelinta kiimikaad iyo kiimiko kiimiko si loo sameeyo filim fosfooreed. Ujeedada ugu weyn ee fosfitinta waa:

1) In la ilaaliyo birta salka ah kana ilaali birta inay daxaloobaan ilaa xad;
2) Waxaa loo istcimaalaa sidii hore ka hor rinjiyeynta si loo hagaajiyo adhesion iyo awoodda ka-hortagga daxalka ee filimka rinjiga.
daawaynta buufin

Waa hab dahaar ah oo loo kala firdhiyo dirays iyo dhibco yaryar iyadoo la adeegsanayo cadaadis ama xoog centrifugal iyada oo la adeegsanayo qori buufin ama atomizer disc, waxaana lagu dhejiyaa dusha shayga si loo jaakadeeyo.
