I-Powder coatings inqubo yokwelapha kuhhavini

I-powder coatings Ukuphulukiswa inqubo kuhhavini siqukethe izigaba ezintathu.

Okokuqala, izinhlayiya eziqinile ziyancibilika, bese zihlangana ndawonye, ​​​​bese ekugcineni zakha ifilimu efanayo noma ukumboza phezulu.
Ukugcina i-viscosity ephansi ye-coating isikhathi esanele kubaluleke kakhulu ukuba ne-surface ebushelelezi futhi elinganayo. Ukuncipha ngesikhathi inqubo yokwelapha, i-viscosity ivame ukwanda ngokushesha nje lapho ukusabela (gelling) kuqala. Ngakho-ke, ukusebenza kabusha nezinga lokushisa lokushisa kunendima ebalulekile ekudaleni indawo esezingeni.
Ngakho-ke, ukuphinda kusebenze kabusha kwe-coating, ukuvela ngokushesha kwe-gelling kanye nokwanda kwe-viscosity, ngenxa yalokho, ingaphezulu le-coating lizoba lukhuni kakhulu (lihlutshiwe i-orange). Ngaphezu kwalokho, ukwelapha ngokushesha kuholela ekwehleni ngokushesha kwe-viscosity encibilikile.

Ukusatshalaliswa kosayizi wezinhlayiya ze-coating nakho kuyasebenza esimweni nasezingeni eliphezulu. Ukuze, uma kuqhathaniswa nezinhlayiya ezinkulu, izinhlayiya ezincane zihlangane nezinye ngesikhathi esifushane. Ukuqedwa kwezinhlayiya ezinkulu kungase kuholele ekubeni nendawo ecwebezelayo necwebezelayo enefilimu ezacile.
