Dahaarka Phosphate Pretreatment for Substrates Birta

Dahaarka Phosphate Pretreatment for Substrates Birta

Daawaynta hore ee la aqoonsan yahay ee substrates-ka birta ka hor inta aan la isticmaalin budada waa fosfatinta taasoo ku kala duwanaan karta miisaanka daahan.

Miisaanka dahaarka beddelka ee weyn ayaa ka weyn heerka caabbinta daxalka ee la gaaro; Miisaanka hoose ee dahaarka ayaa ka sii fiicnaanaya sifooyinka farsamada.

Sidaa darteed waa lagama maarmaan in la doorto tanaasul ka dhexeeya sifooyinka farsamada iyo iska caabinta daxalka. Miisaanka fosfooraska ee sarreeya ayaa dhib ku keeni kara dahaarka budada Jabkaas crystal wuxuu dhici karaa marka dahaarka la hoos geeyo xoogag farsamaysan oo maxalli ah, tusaale ahaan. foorarsanaan ama saameyn.

Sababo la xiriira ku-dhejinta wanaagsan ee daahan budada ah ee daahan fosfooraska, kala diriddu waxay inta badan ka dhici doontaa is-dhexgalka fosfat / birta halkii ay ka ahaan lahayd is-dhexgalka phosphate/budada.

Dahaarka Phosphate waxaa lagu daboolay BS3189/1959, Class C ee zinc phosphate iyo Class D ee fosfatetada birta.
Fosfooraska 'zinc fosfooraska' crystalline hadhuudh wanaagsan ayaa lagula talinayaa dahaarka miisaanka 1-2g/m2 iyo fosfateta birta 0.3-1g/m2. Codsiga waxaa lagu samayn karaa buufin ama maro. Dareenka Chromate inta badan lagama maarmaan ma aha.

Dahaarka fosfooraska birta waxaa sida caadiga ah lagu buufiyaa saddex ama afar marxaladood. Shaqadu waxay inta badan soo martaa laba qaybood oo biyo raaci ah ka hor intaanad engegin.

Fosfooraska Zinc waxa lagu buufin karaa ama lagu shubi karaa hawl shan marxaladood ah, ie. degrease alkali, raaci, zinc phosphate, laba biyo raaci biyo raaci.

Waa lagama maarmaan in qalabka shaqada ka dib fosfatinta uu noqdo budada sida ugu dhakhsaha badan ee suurtogalka ah ka dib marka la qalajiyo.
