The invention discloses a compound herbicide which is suitable for planting tianjing and alfalfa in the Huanghuaihai region. It produces biochemical fulvic acid from fungus residue, wood residue, furfural residue, xylose residue, etc.; then uses biochemical fulvic acid, cyclohexenone herbicides, and imidazolinone herbicides as basic raw materials to produce herbicides agent. The synergistic effect of each component of the invention is obvious, the processing technology is simple, the cost is low, the economic and ecological benefits are remarkable, and the herbicide is an environment-friendly herbicide.

od; the obtained product can satisfy the requirement of the belt tyre; the continual production is adopted to improve the labor productivity greatly which is higher than the intermittent method production level; the quality of the products is ensured to be consistency; the grinding in fluid is adopted to avoid the flammability and explosiveness problems caused by the grinding of the infusible sulfur powder; no <three wastes> is generated so that the producing method belongs to an environmental protection method.The invention provides a method of producing high thermostability insoluble sulfur continuously, which includes the steps that: a melting and heating-up; b the solvent preparation; c reaction; d separation, solidification, grinding and purification; e drying; f screening and oil filling; in the step b, the solvent is composite solvent and composed of carbon bisulfide, dichloromethane and SS auxiliary agent; the weight proportion of the three compositions is 78-95: 5-20: 0.01-2; wherein, the SS auxiliary agent is olefin with unsaturated bonds; the SS auxiliary agent can adopt the Alfa-methylstyrene, isoprene or 1-ethylene-3-cyclohexene. The method of producing high thermostability insoluble sulfur continuously has the advantages that the sulfur is produced through the composite solvent meth

The invention discloses a compounded insecticidal water emulsion containing triazophos and spirodiclofen and a preparation method thereof. The water emulsion comprises the following components in percentage by weight: 10-40% of triazophos and 0.5-10% of spirodiclofen. The insecticidal water emulsion is prepared by carrying out uniform dispersion on the components through a mechanical stirring or high-speed shearing mixing emulsifier. The product has no drug resistance, is high in pesticide effect, has special effect on citrus mite, and simultaneously can be used for treating lepidoptera insects such as phyllocnistis citrella stainton and papilio xuthus Linnaeus. The insecticidal water emulsion has the advantages that water is used as a dispersing medium, environmental pollution is less, no crystallization occurs after the insecticidal water emulsion is stored for two years, the shelf life is long, the nonflammable property is achieved, the storage and transportation are safe, the production technique is simple, the cost is reduced greatly compared with that of single use of the spirodiclofen, and the like.

A water-type pseudo-emulsion of corn protein is proportionally prepared from corn protein, alcohol, plasticizer and distilled water through preparing the alcohol solution of corn protein and plasticizer, and mixing it with water. It can be used to prepare the high-toughness film used as the packing material of medicine, food, paper, etc.

The embodiment of the present invention discloses a mask drying device and a method thereof. The device includes a first drying component, the first drying component includes a first drying porous layer, and the first drying porous layer is disposed opposite to the first surface of the mask. , the first drying porous layer is used to output and heat the wind in the first direction; the first direction is the direction in which the first drying porous layer points to the first surface; the second drying component, the second drying component includes the second drying porous layer, the first drying The second drying porous layer is arranged opposite to the second surface of the mask, and the second drying porous layer is used to output and heat the wind in the second direction; the second direction is the direction in which the second drying porous layer points to the second surface; One surface is the vapor deposition surface of the mask, and the second surface is the opposite surface of the first surface. The technical solutions provided by the embodiments of the present invention improve the stability of the drying effect and reduce the operating cost.
