Embodiment 1

[0041]1. Weigh 100kg desulfurized gypsum, 60kg water, 3kg anion powder, 0.6kg starch and 0.06kg foaming agent;

[0042]2. Divide the negative ion powder into four parts according to the weight ratio of 2:1:1:4, the first negative ion powder is 0.75kg, the second negative ion powder is 0.375kg, the third negative ion powder is 0.375kg, the fourth part The negative ion powder is 1.5 kg; the second negative ion powder and the third negative ion powder are added with water to prepare an aqueous solution of negative ion powder with a concentration of 7.5% by weight;

[0043]3. Add desulfurized gypsum, starch, foaming agent and water to the mixer and mix well;

[0044]4. Add the first negative ion powder at the slurry outlet of the mixer;

[0045]5. Spray the second negative ion powder aqueous solution on the inner surface of the lower face protection paper;

[0046]6. Before the final setting of the gypsum slurry, cut off the part of the upper face paper that needs to be shaped, and spray the third par...

Embodiment 2

[0055]The difference between this embodiment and embodiment 1 is only that: the water consumption is 70kg, all 3kg of negative ion powder is added at the slurry outlet of the mixer, and the inner surface of the upper and lower face protection paper is not sprayed with the negative ion powder aqueous solution.

Embodiment 3

[0057]The difference between this embodiment and embodiment 1 is only: 3kg of negative ion powder is divided into three parts according to the weight ratio of 3:1:1, the first part of negative ion powder is 1.8kg, which is added at the outlet of the slurry; , Three parts of negative ion powder are 0.6kg, add water to prepare an aqueous solution of negative ion powder with a concentration of 12% by weight, and spray them on the inner surface of the upper and lower masks respectively. The upper mask is not cut, and the upper mask is not shaped.

Abstract

The present invention discloses a method for preparing a plasterboard capable of purifying air. The method comprises: adding negative ion powder to a plasterboard, wherein the adding amount of the negative ion powder is 1-5 parts by weight based on 100 parts by weight of desulfuration gypsum for preparing the plasterboard, the negative ion powder is added to a material slurry for preparing the plasterboard from a material slurry outlet, and negative ion powder aqueous solutions prepared from the negative ion powder are sprayed onto the inner surfaces of upper surface protection paper and lowersurface protection paper of the plasterboard. According to the present invention, the obtained plasterboard can release negative ions into the air, and has good and long-lasting air purifying ability, and the surface of the plasterboard has the three-dimensional shape and the embossed hole with a certain shape so as to achieve the beautiful and elegant characteristics.

Description

Technical field[0001]This application relates to but not limited to the technical field of production of gypsum board, and specifically relates to but not limited to a method for preparing gypsum board that can purify air.Background technique[0002]Paper-faced gypsum board is a new type of building material with many properties such as light weight, convenient processing, heat and sound insulation, excellent fire resistance and breathing performance, and has been widely used in various occasions. Paper-faced gypsum board is a porous product, which can purify the air to a certain extent, but the effect is not ideal. In particular, the current overall air environment is worrying, so preparing a plasterboard that can purify indoor air can greatly improve the living environment, which is very meaningful.Summary of the invention[0003]The following is an overview of the topics detailed in this article. This summary is not intended to limit the scope of protection of the claims.[0004]This a...
