Embodiment 1

[0042] 1. Weigh 100kg desulfurized gypsum, 60kg water, 3kg negative ion powder, 0.6kg starch and 0.06kg foaming agent;

[0043] 2. Divide the negative ion powder into four parts according to the weight ratio of 2:1:1:4, the first part of negative ion powder is 0.75kg, the second part of negative ion powder is 0.375kg, the third part of negative ion powder is 0.375kg, and the fourth part Negative ion powder is 1.5kg; The second part of negative ion powder and the third part of negative ion powder are added with water respectively to be mixed with the negative ion powder aqueous solution that concentration is 7.5% by weight;

[0044] 3. Add desulfurized gypsum, starch, foaming agent and water into the mixer and mix well;

[0045] 4. Add the first negative ion powder at the slurry outlet of the mixer;

[0046] 5. Spray the anion powder aqueous solution prepared by the second part of anion powder onto the inner surface of the lower face paper;

[0047] 6. Before the final settin...

Embodiment 2

[0056] The difference between this embodiment and Example 1 is only: 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 papers is not sprayed with negative ion powder aqueous solution.

Embodiment 3

[0058] The difference between this embodiment and Example 1 is only that: 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, and it is added at the outlet of the slurry; the second , three parts of negative ion powder are 0.6kg, after adding water and being mixed with the negative ion powder aqueous solution that concentration is 12% by weight, be sprayed on the inner surface of upper protective paper and lower protective paper respectively. No cutting is done on the upper protective paper, and no shaping is done on the upper protective paper.

Abstract

The present invention discloses a plasterboard capable of purifying air, wherein the plasterboard comprises negative ion powder, 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 the negative ion powder aqueous solutions are prepared, and are sprayed onto the inner surfaces of upper surface protection paper and lower surface protection paper of the plasterboard. According tothe 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 gypsum board production, in particular to but not limited to an air-purifying gypsum board produced by using negative ion powder and desulfurized gypsum. Background technique [0002] Paper-faced gypsum board is a new type of building material, which has many properties such as light weight, convenient processing, heat and sound insulation, fire resistance and breathability, and has been widely used in various occasions. Paper-faced gypsum board is a kind of porous product, which has a certain effect of purifying the air, but the effect is not ideal. Especially the current overall air environment is worrying, so preparing a kind of paper-faced gypsum board that can purify indoor air can greatly improve the living environment, which is very meaningful. Contents of the invention [0003] The following is an overview of the topics described in detail in this article. This summary is...
