Yini okufanele inakeke lapho ikhetha ukumbona kwepulasitiki?

Kunezinhlobo eziningi zeIzambatho zepulasitikiemakethe. Lapho ukhetha ukuthenga, ikakhulukazi kuncike kwizidingo zesimo sohlelo lokusebenza lokuhlanganisa kanye nokusebenza kwe-coating uqobo. Okulandelayo, sizoqala ngamaphuzu alandelayo:

1. Adhesion

Izambatho zepulasitikiube nokunamathelisa okuhle, okulungele ukugwema inkinga yokuchitheka okulandelayo kwe-coating. Ngasikhathi sinye, ngaphambi kokwakhiwa, indawo epulasitiki kufanele ihlanzwe kahle ukuze ikhiphe ukungcola okufana nama-ejenti wokukhulula namabala kawoyela. Uma kunesidingo, ukwelashwa kokugaya noma kwamakhemikhali kufanele kusetshenziselwe ukuthuthukisa ukunamathela.

2. Ukumelana kwamakhemikhali kanye nokumelana kawoyela

Ukukhethwa kweIzambatho zepulasitikiidinga ukucubungula izidingo zesimo sohlelo lokusebenza. Uma amabala kawoyela noma izixazululo zamakhemikhali zibandakanyeka, ukumbona okuvimbela uwoyela okufana nama-epoxy resins nama-polyurethanes kudingeka kukhethwe.

3. Ukuqina okushisayo kanye nokumelana nesimo sezulu

Inhloso yokukhethaIzambatho zepulasitikiNgokuqina okuphezulu okushisayo ukuvimbela ukubola noma ukuncipha emazingeni okushisa aphezulu. Uma isimo sohlelo lokusebenza singaphandle, kuyadingeka ukuqinisa ukumelana kwe-UV nokumelana nesimo sezulu kwenhlanganisela yepulasitiki ukugwema ukuguga kanye nokwakheka kwe-coating ngenxa yokukhanya isikhathi eside.
