Qalabaynta balaastikada deegaanka u fiican

Iyada oo la adeegsanayo qaab-dhismeedkeeda polyol (C ? H ?? O ?) si loogu beddelo phthalates, balaastikada aan sunta ahayn iyo kuwa noolaha ah ayaa loo soo saaray baakadaha qalabka caafimaadka iyo alaabta carruurtu ku ciyaarto.

Faa'iidooyinka: noole ku habboonaanta sare, ma jirto khatar hormoon deegaan ah.

Wax ka beddelka dahaarka iyo resinka

Synthesis of alkyd resin: Shan kooxood oo hydroxyl ah waxay la falgalaan asiidh dufan leh si ay u soo saaraan adayg sare, dahaarka u adkaysta cimilada halkii glycerol, hoos u dhigista isticmaalka saliidda 30%.

Hagaajinta resin-ka phenolic: kopolymerized leh rosin glyceride si kor loogu qaado dabacsanaanta iyo dhejinta filimka rinjiga.

Dusha wax soo saarka wakiilka firfircoon

Waxay la falgashaa saliidda Tar si ay u soo saarto emulsifiers bio ku salaysan, oo ku habboon firdhiya sunta cayayaanka iyo kuwa nadiifiya goobaha saliidda, oo leh heer nabaad-guur 50% ka sarreeya badeecadaha ku salaysan batroolka
