Embodiment Construction
[0016] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0017] please see figure 1 , this creation is about a method of making a fireproof coating and a fireproof body. Firstly, take industrial wastewater, and the industrial wastewater must contain calcium sulfate, and then use the ultraviolet-visible light spectroscopic brightness measurement with a wavelength of 275nm to measure the The concentration range, and then according to the Ca 2+ and The molar ratio of 1:1 determines the amount of calcium chloride solution added. Then pour the industrial waste water and the calcium chloride solution into a container for mixing, and a magnet can be added during the mixing process to help the mixing effect. In addition, take a sodium hydroxide container and pour it into the container, and adjust t...

Abstract
The invention provides a preparation method of a fireproof coating and a fireproof wall. The preparation method comprises the following steps of: preparing calcium sulfate whiskers by utilizing industrial wastewater and a microwave heating method, mixing the industrial wastewater with a calcium chloride solution in a container, heating by using the microwave heating method to generate white calcium sulfate seed crystals at the bottom of the container, washing the calcium sulfate seed crystals by using distilled water to obtain calcium sulfate slurry, pouring sodium hypophosphite and distilled water into the container, heating by using the microwave heating method, finally pouring the liquid in the container on the surface of nylon, collecting the liquid passing through the nylon, and drying to obtain the calcium sulfate whiskers; and adding the calcium sulfate whiskers into the coating to obtain the fireproof coating, coating the fireproof coating on the surface of the wall, and forming a fireproof coating on the surface of the wall after the fireproof coating is solidified, thereby obtaining the fireproof wall. The microwave heating method is mainly utilized in the invention, so that the preparation method has the advantages of high heating speed, easily controlled heating process, high efficiency, simplicity in operation and the like, and the calcium sulfate whiskers can be prepared more efficiently.
Description
technical field [0001] The invention relates to the field of fire prevention, in particular to a method for making a fire prevention coating and a fire protection body. Background technique [0002] Calcium sulfate whiskers are widely used in fireproof building materials due to their large surface area, high strength, high temperature resistance, corrosion resistance, and low price. By making the calcium sulfate whiskers into fireproof coatings, And the fireproof coating is applied on the surface of the wall, so that the surface of the wall forms a fireproof coating, so that the whole has effects such as high temperature resistance and fire prevention. [0003] At present, the main ways to produce calcium sulfate whiskers are: preparing calcium sulfate whiskers from calcium carbide slag, preparing calcium sulfate whiskers from brine slag from seawater, directly preparing calcium sulfate whiskers from gas desulfurization, and preparing calcium sulfate crystals from citric aci...
