La dhajiyay 2018-10-29Iyada oo horumarka degdega ah ee tignoolajiyada wax soo saarka casriga ah, wax soo saar badan oo tignoolajiyada sare ah ayaa loo isticmaalaa wax soo saarka, gaar ahaan warshadaha wax soo saarka.Farsamaynta farsamaynta ayaa nolosheena u keentay raaxo badan, oo ay ku jiraan daaha Dacromet.
Dacromet dacromet, oo sidoo kale loo yaqaan daahan zinc flake, ayaa si weyn looga isticmaalaa warshado badan.Waxaa ka mid ah, isku-dhafka tignoolajiyada Dacromet iyo dahaarka ayaa si weyn u wanaajiya waxqabadka ka-hortagga daxalka ee alaabta.Markaa ma ogtahay sababta ay u ilaalin karto walxaha?
Daahan Dacromet waa matt silver-cawlan wuxuuna ka kooban yahay jajabyo aad u fiican oo zinc, aluminium iyo chromate ah.Ka dib markii shaqada la gooyay oo la toogtay, dahaarka waxaa lagu dahaadhay Dacromet.Dacromet daahan waa nooc ka mid ah dareeraha wax lagu dhaqo ee biyaha ku salaysan, oo loogu talagalay ka baaraandegidda qaybaha birta ka dib daahan ama buraashka buufin ee dareeraha, galka foornada, qiyaastii 300 ℃ filimka dubista, si ay u sameeyaan zinc, aluminium, chromium, daahan inorganic.
Inta lagu jiro habka daaweynta, walxaha biyaha iyo organic (cellulose) ee daahan ayaa isbedelay iyagoo ku tiirsan oksidization ee cusbada chromium ee qiimaha sare leh ee khamriga hooyada ee dacromet, iyo xeryahooda cusbada chromium ee Fe, Zn iyo Al ayaa la sameeyay ka dib falcelinta xaashida zinc-ka ah iyo slurry xaashida aluminium oo leh awood koronto weyn oo taban oo leh matrix bir ah.Sababtoo ah lakabka xuubka ayaa la soo saaraa ka dib falcelinta tooska ah ee matrixka, dahaarka ayaa ah mid aad u adag. In jawiga daxalka ah, daahanku wuxuu sameeyaa unugyo galvanic ah oo badan, taas oo ah, marka hore waxay daxalisaa cusbada Al iyo Zn taban ilaa ay wada baabbi'iyaan ka hor intaanay dhicin. waxay u badan tahay in ay ku daxaloobaan matrixka laftiisa.
