Embodiment 1
[0010] Embodiment 1: the gypsum powder of gypsum board batching is 30 tons, and the fly ash that weight ratio is 1-5‰ is 0.03-0.15 tons, and the lime that weight ratio is 1-5% is 0.03-0.15 tons, and weight is 1-5% The 5% calcium carbonate is 0.03-0.15 tons. After adding water and mixing according to the conventional process, it is made into a 9.5mm gypsum board. The measured strength has been enhanced, which can effectively remove the content of smog in the air.
[0011] Place the prepared anti-fog plasterboard for a period of time for real-time testing, obtain the test data in the table, and draw the curve of the anti-fog plasterboard absorbing the haze as shown in figure 1 shown.
[0012] The anti-smog function of the present invention is embodied below by tabular form:

The invention discloses a formula of a paper covered gypsum board capable of eliminating haze, and relates to the field of paper covered gypsum board function extension. The paper covered gypsum board comprises 0.1 to 0.5 wt% of diatom ooze, 0.1 to 0.5 wt% of lime, and 0.1 to 0.5 wt% of calcium carbonate. Due to the large specific area and special structure of diatom ooze, the haze molecules can be absorbed physically; water molecules in haze can be absorbed by anhydrous gypsum (III) and semi-hydrated gypsum in gypsum board; alkaline substances such as lime, calcium carbonate, and the like, react with acidic components, thus haze molecules are absorbed and removed, the quality of indoor air is effectively improved, the added lime enhances the strength of gypsum board, and the performance of gypsum board is further strengthened.
Description
technical field [0001] The invention relates to the field of functional expansion of gypsum boards, in particular to a formula for gypsum boards capable of removing haze. Background technique [0002] Smog, as the name suggests, is fog and haze. Fog is an aerosol system composed of a large number of tiny water droplets and ice crystals suspended in the air near the ground, while haze is an aerosol system composed of dust, sulfuric acid, nitric acid and other particles in the air. At present, because most of the industrial gypsum is used as the raw material for the production of gypsum boards, a large number of gypsum boards produced are used for interior decoration. And the appearance of smog seriously threatens people's health, so far there is no effective indoor decoration material for removing smog. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a formula for gypsum board that can remove smog...
