The invention discloses a low-temperature curing powder coating. The coating is prepared from the following raw materials in parts by weight: 60-70 parts of epoxy resin, 2-3 parts of a low-temperaturecuring agent, 0-1.5 parts of a leveling agent, 0-1.5 parts of a wetting agent, 20-35 parts of precipitated barium sulfate, 0.5-1.5 parts of a curing accelerator and 0-2 parts of other auxiliary agents, wherein the low-temperature curing agent is a modified imidazole compound, and the curing accelerator is prepared from the following raw materials in parts by weight: 65-70 parts of glycidyl etherand 30-35 parts of fumed silica. The invention also discloses a preparation method and application of the low-temperature curing powder coating. Through the synergistic effect of the low-temperature curing agent and the curing accelerator and the optimization of a formula, the powder coating prepared by the formula can be fully cured by performing heat preservation at the temperature of 100-120 DEG C for 5-20 minutes, the powder coating prepared by the formula has a low curing temperature and better room temperature storage performance, and the coating has low-temperature curing performance and room temperature storage performance at the same time.

The invention provides a method of using potato raw material to prepare ethanol. The method comprises the steps of crushing peeled potato raw material, and mixing the crushed product with enzyme for enzyme digestion to obtain a zymohydrolysis product, wherein, the crushing method comprises the steps of crushing the peeled potato raw material for one time to obtain a primary crushed product, crushing part of the primary crushed product for the second time to obtain a secondary crushed product, mixing the remaining part of the primary crushed product with the potato raw material peeled but not crashed and crushing once. With the method, water and energy consumption are less and the equipment utilization rate and the crushing efficiency are high; meanwhile, the secondary crushing method can better control the grain diameter of particles of the potato raw materials in the crushed product obtained by crushing, thereby the grain diameter of the particles of the potato raw materials which are finally obtained is small and even..

The method for synthesizing high alpha-phase silicon nitride powder body by utilizing low-pressure combustion includes the following steps: firstly, pretreating raw material metal silicon powder, according to proportion adding activating agent, diluting agent and additive, ball grinding, fully mixing them, drying, placing them into low-pressure combustion synthesis reaction equipment, evacuating, blowing nitrogen gas into the reaction equipment from bottom, inducing to combustion to implement suspension nitrogenation at low pressure. The purity of said invented product is high, and its alpha-phase content is high.

The invention discloses an ethanol preparation method that utilizes raw potato materials and comprises following steps: the raw potato materials are crashed, the crashed product is mixed with an enzyme, zymolysis is carried out so as to obtain a zymolysis product, and the zymolysis product is fermented, wherein, the crashing method comprises carrying out primary crashing of the raw potato materials to obtain a primary crashed product, carrying out secondary crashing of part of the primary crashed product to obtain a secondary crashed product, mixing left part of the primary crashed product with un-crashed raw potato materials and then carrying out primary crashing of the mixture. The ethanol preparation method not only can consume less water and less energy, and achieve high device utilization rate and high crashing efficiency, but also can achieve better control on the grain diameter of raw potato material particles in the crashed products that are obtained by crashing as well as small and even grain diameter of the final raw potato material particles by adopting the secondary crashing method.

The invention relates to allochroic artificial leather which sequentially comprises a surface layer, an allochroic layer and a foaming layer from top to bottom. The surface layer is prepared from, by weight, 100 parts of polyurethane resin and 80-100 parts of organic solvent; the allochroic layer is prepared from, by weight, 100 parts of polyvinyl chloride resin, 80-100 parts of dioctyl phthalate, 40-60 parts of calcium bicarbonate, 1-3 parts of heat stabilizers and 3-5 parts of PVC color paste; the foaming layer is prepared from, by weight, 100 parts of polyvinyl chloride resin, 80-90 parts of dioctyl phthalate, 60-70 parts of filling agents, 2-3 parts of stabilizers and 3-4 parts of foaming agents. The invention further relates to a preparation method of the allochroic artificial leather. The allochroic artificial leather has the advantages of significantly improving the wear-resisting property of the overall structure of the allochroic artificial leather.

The invention provides a method for preparing alcohol by utilizing potato materials. The productivity of the starch-alcohol of the alcohol obtained by the method is obviously higher than that of the starch-alcohol of the alcohol obtained by the reference methods, and compared with the prior art, the residual sugar rate in the method of the invention is greatly reduced. Meanwhile, the method provided by the invention obviously shortens the solid-liquid separation time and increases the treatment capacity of the liquid waste in unit time under the condition of dispensing with new equipment, thus overcoming the bottleneck that the device used for preparing the alcohol by fermenting cassava has relatively low operation load and increasing the production capacity of the device.

The invention relates to a production method of low-salt salted eggs. The production method comprises the following steps of selecting fissureless fresh eggs being uniform in size, thoroughly cleaning the selected fresh eggs with clean water, adding pickling liquid to the cleaned fresh eggs until the level of the pickling liquid is just higher than the surfaces of the eggs, then performing sealed pickling under the environment of 15-30 DEG C for 40-50 days, fishing out the pickled eggs, thoroughly cleaning the pickling liquid on the surfaces of the eggs, and draining the water on the surfaces of the cleaned eggs, wherein the pickling liquid consists of the following components in parts by weight: 100 parts of water, 8-16 parts of table salt, 100-180 parts of white sugar and 0.5-1 part of edible Baijiu of 50 V / V. The production method disclosed by the invention is simple to operate, the made salted eggs are moderate in salinity, the salinity of egg white in the salted eggs is about 3%, the inherent characters of the salted eggs can be maintained, and the products are uniform in quality and good in consistency.
