Två huvudsakliga metoder för att göra PVC

Visningar: 0 Författare: Webbplatsredaktör Publiceringstid: 2021-04-21 Ursprung: Plats

Det finns två huvudsakliga metoder för att tillverka PVC: kalciumkarbidmetoden och etenmetoden.

Kalciumkarbidmetoden är en kemisk reaktionsmetod som använder kalciumkarbid (kalciumkarbid) för att generera acetylen när den möter vatten, syntetisera acetylen och väteklorid för att producera vinylkloridmonomer och sedan polymerisera vinylklorid för att producera polyvinylklorid. Etenmetoden är att extrahera eten från petroleum, låta klor reagera med eten för att producera vinylkloridmonomer, som polymeriseras för att producera polyvinylkloridharts.
