The invention discloses an antibacterial and antiviral inorganic ceramic interior wall coating and a preparation method thereof. The interior wall coating includes a primer and a finishing paint, wherein the primer comprises the following components in percentage by weight, on the basis of 100%: 10-15% of potassium silicate, 10-20% of silica sol, 5-10% of acrylic emulsion, 35-45% of filler, 1-2% of defoaming agent and the balance of deionized water; and the finishing paint comprises the following components in percentage by weight, on the basis of 100%: 15 to 20 percent of sol, 10 to 15 percent of methyltrimethoxysilane, 15 to 20 percent of silicone acrylic emulsion, 0.5 to 0.8 percent of 20 percent formic acid solution, 0.5 to 1 percent of graphene oxide, 8 to 10 percent of nano aluminum oxide, 12 to 15 percent of inorganic pigment, 0.5 to 1 percent of p-tert-butylcatechol, 2 to 3 percent of methanol and the balance of deionized water. The coating is safe and environment-friendly, has excellent water resistance, air permeability, water impermeability and excellent mildew-proof effect, dust is not easy to fall on a wall veneer, stains are not easy to adhere to the wall veneer, the coating is easy to clean, the scrubbing resistance can reach more than 100,000 times, and the coating has lasting antibacterial and antiviral capabilities.

Provided are a photocatalytic titanium oxide capable of demonstrating antibacterial and antiviral effect when used in various applications, as well as an antibacterial, antiviral photocatalytic titanium oxide slurry in which the photocatalytic titanium oxide has been stably dispersed in a neutral area, and a method for manufacturing same. An antibacterial, antiviral photocatalytic titanium oxide, wherein 0.1 to 50 mass by weight in terms of the copper standard of at least one species selected from copper (II) phosphate and copper (II) pyrophosphate with respect to 100 mass by weight of titanium oxide particles is carried on at least the surface of the titanium oxide particles, and the 50% cumulative particle diameter (D50) (light scattering intensity standard) is 5 to 200 nm.

The invention relates to a method for mixed culturing of swimming crabs and palaemon carinicauda. The method belongs to the technical field of fishery industry and is characterized by comprising the following steps of (1) clearing up a pond; (3) putting swimming crab seedlings in mid-to-end of May, selecting III-period baby crabs cultivated in a soil pool, putting 1-1.5kg per mu, in the end of June, putting 1-2kg of lively-swimming egg-carried shrimps per mu, and planting submerged plant water caltrop in the bottom part of the pond for improving water quality; (4) replacing 70-80 percent of water at every 5-7 days, sterilizing in time after water replacement, and putting water quality modifying agent for one time at the second day; (5) feeding crab and shrimp mixed feed, and then feeding according to the conventional mixed culturing method of the swimming crabs and palaemon carinicauda. According to the method for the mixed culturing of the swimming crabs and the palaemon carinicauda, the nutrition is balanced, the daily demands of the swimming crabs and palaemon carinicauda can be met, the feed efficiency is high, the survival rate of the swimming crabs and palaemon carinicauda is high, the ponderal growth is quick, the immunity of crab bodies can be remarkably enhanced, and the capabilities of antibiosis and antiviral of the crab bodies are improved.

The invention relates to the field of veterinary disinfection powder, and in particular relates to a body surface drying disinfection powder for newborn piglet and a preparation method thereof. The body surface drying disinfection powder for newborn piglet provided by the invention comprises, by weight, 64%-96% of montmorillonite, 1.6% of a Picrasma quassioides extract, 1.0% of a licorice extract, 0.4% of a honeysuckle extract, 0.4% of a macleaya cordata extract and 0.6% of a mint extract, and further comprises talc no higher than 32%. The invention has the advantage that the drying disinfection powder employs high purity montmorillonite with effects of drying, adsorbing harmful microorganisms and toxins, and protecting the digestive tract mucosa, and the montmorillonite is combined with Chinese herbal medicine additives with antibacterial and antivirus action (including Picrasma quassioides extract and licorice extract), so as to enhance antibacterial and antiviral effect on the premise of ensuring product drying effect. The body surface drying disinfection powder for newborn piglet can effectively reduce the impact of harmful microorganisms in environment, and at the same time has a good cholagogic, hemostatic and white blood cell increasing efficacies.

The invention relates to a transparent antibacterial antiviral self-cleaning coating solution and a use method thereof. The coating solution comprises the following components in parts by weight: 1-4parts of polymethyl methacrylate, 0.01-2 part of nano zinc oxide, 0.5-3 part of a silver-containing solution, 1-3 parts of a silane coupling agent, 0.5-2 part of an adhesion promoter and 90-110 partsof a solvent. The prepared coating solution is uniformly coated on the surface of a base material subjected to heat treatment at 70-150 DEG C, and annealing treatment is carried out to obtain the basematerial with a transparent antibacterial antiviral self-cleaning coating. The coating solution is obtained by compounding polymethyl methacrylate and nano zinc oxide, so that the comprehensive performance of polymethyl methacrylate is improved, the adhesive force of the coating to the surface of the base material can be effectively improved, and the obtained base material with the coating has antibacterial and antiviral performance and certain self-cleaning capacity, and also has good transparency and anti-ultraviolet capability.
