Document Type and Number:
WIPO Patent Application WO/2020/224120
Kind Code:
A1
Abstract:
A high impurity ion content desulfurized gypsum paper-faced gypsum board and a manufacturing method therefor. The paper-faced gypsum board comprises a board core and protective paper outside the board core; raw materials of the board core comprise 100 parts by weight of a desulfurized gypsum raw material and 0.5-10 parts by weight of zeolite; the desulfurized gypsum raw material is selected from any one or more of a high-sodium desulfurized gypsum raw material, a high-magnesium desulfurized gypsum raw material, a high-potassium desulfurized gypsum raw material, and a high-chlorine desulfurized gypsum raw material. The zeolite is a modified zeolite; or, an adsorption material is provided on one side of the protective paper in contact with the board core, and the adsorption material is selected from any one or more of zeolite, diatomaceous earth, fly ash, attapulgite clay, and bentonite.
