The invention discloses a production device of potassium dimethyldithiocarbamate and a preparation method thereof. The production device comprises a reaction kettle, wherein a dimethylamine overhead tank, a sulfur dioxide overhead tank, a potassium hydroxide overhead tank and a soft water overhead tank are respectively communicated to the upper part of the reaction kettle through pipelines; and a filter and an end product storage tank are sequentially and respectively communicated with a reaction kettle discharging valve through pipelines. The production method comprises the steps of: respectively metering carbon disulfide, concentration potassium hydroxide solution with the concentration of 40%, concentration dimethylamine solution with the concentration of 50% and softened water in proportion by mass, firstly putting the concentration dimethylamine solution with the concentration of 50% into the reaction kettle, starting stirring, and introducing cooling media into a reaction kettle jacket and an inner cooling coil by utilizing a cooler; when the kettle temperature decreases to 5-20 DEG C, respectively adding the carbon disulfide and concentration potassium hydroxide solution with the concentration of 40% into the reaction kettle, then adding the softened water, after reacting for 100-150min, slowly opening the reaction kettle discharging valve, and sequentially pressing materials in the reaction kettle into a filter and the end product storage tank.

The invention discloses a rapid-vulcanized low-smoke halogen-free flame retardant rubber cable material. The rapid-vulcanized low-smoke halogen-free flame retardant rubber cable material mainly comprises the following raw materials in parts by weight: 20-80 parts of natural rubber, 20-80 parts of butadiene-styrene rubber, 130-150 parts of flame retardant smoke suppression agent, 4-10 parts of flame retardant smoke suppression synergist, 1-3 parts of coupling agent, 1-3 parts of zinc dimethyldithiocarbamate, 1-5 of vulcanizing agent, 6-8 parts of zinc oxide, 1-3 parts of stearic acid and 1-2 parts of antioxidant. The rapid-vulcanized low-smoke halogen-free flame retardant rubber cable material has the beneficial effects that the cable material is easy to machine, an extruded wrapping technology is good, and products have good mechanical property and good low-temperature flexibility.

The invention discloses a trunk disease therapeutical agent. The therapeutical agent is prepared by mixing and processing ziram, bavistin, tebuconazole, hexaconazole, flusilazole, propiconazol and the like which serve as active ingredients for single use or composite use, a compound amino acid, a humic acid and sodium nitrophenolate which serve as auxiliary agents, and organosilicon, white carbonblack and the like. The therapeutical agent can effectively prevent and control main pathogenic bacteria of trunks and has the characteristics of high prevention-control rate, remarkable prevention-control effect, high efficiency, low toxicity, low residual, low cost and convenient use.

The invention provides a preparation method of nano gold immobilized pellets and application of the nano gold immobilized pellets to ziram detection. The preparation method comprises the following steps: weighing ditert-butyl bicarbonate, NHS and EDC, adding the ditert-butyl bicarbonate, the NHS and the EDC into an MES buffer solution for stirring reaction, adding a chitosan solution for reactionover night, and placing the solution in an ultrafiltration pipe for centrifugal ultrafiltration, thereby obtaining a chitosan grafted tyrosine solution; then adding a chloroaurate aqueous solution into the chitosan grafted tyrosine solution, adjusting the pH value, uniformly shaking the mixed solution, and stewing to obtain a chitosan-nano gold solution; mixing the obtained chitosan-nano gold solution with epoxy chloropropane, dropwise adding the mixture into a sodium hydroxide solution, filtering out suspended pellets in the solution, and drying the pellets, thereby obtaining the nano gold immobilized pellets. The nano gold immobilized pellets prepared by the preparation method provided by the invention are easy to store and high in stability, do not need to be prepared for instant use, and is convenient to use; when the nano gold immobilized pellets are applied to the ziram detection, a detection system is high in stability, and a detection result is high in repetitiveness and reliability.
