Embodiment 1
[0048] A preparation method of a monatomic gypsum material for preventing and controlling African swine fever virus ASFV, comprising the following steps:
[0049] S1, the preparation of single-atom materials, which specifically includes the following steps:
[0050] S11, the preparation of porous raw gypsum carrier, the specific steps are:
[0051] S111, adding 100 g of a sodium carbonate solution of PH=8 to 100 g of raw gypsum with a particle size of 100 mesh, and mixing and stirring the two at room temperature and a rotating speed of 500 rpm for 1 hour, so that the solution fully undergoes a metathesis reaction;
[0052] S112, repeatedly washing and filtering the mixture prepared in S111 to neutrality, and placing the solid in a blast drying oven at 80° C. for 2 hours;
[0053] S113, roasting and puffing, the dried product in S112 is roasted for 10 minutes under the conditions of 550°C and 0.8MPa internal pressure in the reactor, and after the roasting is completed, cool to...
Embodiment 2
[0060] The difference between embodiment 2 and embodiment 1 is: the selection of transition metal nitrate aqueous solution in S12 is different, and the transition metal nitrate aqueous solution used in embodiment 2 in S12 includes 5g / L silver nitrate and 100g / L zinc nitrate aqueous solution.
Embodiment 3
[0062] The difference between embodiment 3 and embodiment 1 is: the selection of transition metal nitrate aqueous solution is different in S12, and the transition metal nitrate aqueous solution used in embodiment 3 in S12 comprises 5g / L silver nitrate, 200g / L copper nitrate and 200g / L L zinc nitrate aqueous solution, wherein the volume ratio of 5g / L silver nitrate, 200g / L copper nitrate and 200g / L zinc nitrate aqueous solution is 1:1:1.

Abstract
The invention relates to the technical field of functional gypsum materials, and particularly discloses a monatomic gypsum material for preventing and controlling African swine fever virus (ASFV). The monatomic gypsum material for preventing and controlling African swine fever virus (ASFV) is prepared from the following raw materials: a monatomic material and building gypsum, wherein the mass ratio of the monatomic material to the building gypsum is 1: (7-10). The preparation method comprises the following steps: S1, preparing a monatomic material; and S2, building gypsum and the monatomic material in step S1 are uniformly mixed in proportion to prepare the monatomic gypsum material, wherein the particle size of the building gypsum is 80-150 meshes. The monatomic gypsum material for preventing and controlling the ASFV can be used for being brushed in the environment of a farm, including the ground, the wall surface, the trough, the pedestrian path and other corners of a hog house, and has the advantage of efficiently and permanently inactivating the ASFV, and in addition, the preparation method has the advantages of being simple and easy to operate.
Description
technical field [0001] The application relates to the technical field of functional gypsum materials, more specifically, it relates to a single-atom gypsum material for preventing and controlling African swine fever virus ASFV and a preparation method thereof. Background technique [0002] African swine fever is a severe infectious disease caused by African swine fever virus ASFV infecting domestic pigs. The World Organization for Animal Health (OIE) has listed it as a legal animal disease, and this disease is also a class of animal epidemics that my country focuses on preventing. The onset of African swine fever is short, and its pathogenicity rate to pigs is extremely high, with a lethality rate of 100%. Its symptoms are similar to those of swine fever, and it can only be confirmed by laboratory testing, so it is difficult to prevent the epidemic. [0003] African swine fever has six main transmission routes, namely airborne infection, mosquito bites or fly transmission, ...
