The invention belongs to the technical field of copper clad laminates and particularly relates to a resin composition, prepreg using the resin composition and a laminate. The resin composition contains the ingredients in percentage by weight: 15-55% of amine modified bismaleimide (BMI), 10-45% of benzoxazine resin and 0-75% of epoxy resin. According to the resin composition, through further reaction of benzoxazine (BOZ) and amine modified bismaleimide (BMI), performance advantages of two kinds of high-performance resin, namely BMI and BOZ, are excellently exerted, so that the prepreg and the copper clad laminates, manufactured from the resin composition, have the properties of high Tg, relatively high peeling strength, relatively low CTE, relatively low water absorbing capacity, relatively low dielectric loss, relatively high elastic modulus high-temperature retention rate, relatively good resistance to hot and damp and the like, and reach a flame-retardant level UL94-V0.

The invention discloses a high-temperature resistant quartz flexure accelerometer, and the flexure accelerometer comprises a meter head and a servo circuit, wherein the meter head and the servo circuit are welded through a wire to form electrical connection. The housing of the servo circuit and the meter head are welded through a laser welding machine to form an integrated machine. The meter head comprises a meter core, a housing, and an isolating ring. The meter core comprises a quartz swinging piece assembly, an upper torquer, and a lower torquer. The upper and lower torquers respectively comprise a magnetic steel, which is a samarium cobalt magnetic steel, wherein the mass ratio of all elements in the samarium cobalt magnetic steels (samarium: cobalt: ferrum: copper: zirconium: praseodymium) is 2: 25: 1.5: 0.1: 0.05: 0.08. According to the invention, the flexure accelerometer can enable the resisted temperature of the flexure accelerometer to be increased to 180 DEG C, and the temperature coefficient of a scale factor (K1) of the flexure accelerometer is controlled to be less than 200ppm/DEG C. Moreover, the flexure accelerometer can work under 200 DEG C for at least four hours.

The invention discloses a formula of an artificial mixed feed for adult reeves shad. The artificial mixed feed comprises the following components by percentage: 18 percent of white fish meal, 30 percent of red fish meal, 20 percent of first patent flour, 17 percent of bean pulp, 3 percent of beer yeast, 1 percent of gluten flour, 1 percent of squid powder, 0.1 percent of methionine, 0.3 percent of lysine, 0.3 percent of betaine, 2 percent of composite multi-dimensional, 1.5 percent of composite multi-minerals, 0.3 percent of Vc wax, 0.2 percent of gallbladder smoother, 0.6 percent of monocalcium phosphate, 0.5 percent of soya bean lecithin, 4 percent of mixed oil and 0.2 percent of Immune polysaccharide; meanwhile, the processing requirements are provided, unqualified raw materials and raw materials harmful to a human body are prohibited, and the compatibility of the components is kept in mixing and processing. By the artificial mixed feed, the growth speed of the adult reeves shad isimproved, the feed coefficient is reduced, and the taste of the reeves shad is improved. Through experiments and years of culture condition statistics, the average rate of body weight gain in half a year is 1,758.6 percent, and the feed coefficient reaches 1.8. The formula of the feed and the processing technology meet nutritional requirement and intake requirement of the adult reeves shad in various culture stages.

The invention discloses temperature-resistant frosted soft sweets. The temperature-resistant frosted soft sweets are prepared from the following raw materials in parts by weight: 6 to 12 parts of gelatin, 0.4 to 1.2 parts of pectin, 3 to 8 parts of modified starch, 0.05 to 0.5 part of gellan gum, 15 to 25 parts of malt syrup and/or maltitol, 40 to 50 parts of white granulated sugar, 3 to 10 partsof glucose and 0.5 to 2 parts of total acid, wherein the total acid is a mixture of citric acid, DL-malic acid and buffered lactic acid. After the soft sweets provided by the invention are dried, frosted layers with uniform thickness are formed on the surfaces of the soft sweets in a moisture balance period, so that improvement on the taste of the soft sweets is facilitated; after the frosted layers are formed on the surface, cut-off performance of the soft sweets is enhanced, and the soft sweets are chewed more easily, temperature resistance performance of the soft sweets is further improved,long-distance transportation in high-temperature summer season can be endured, and the stability of the soft sweets is ensured. Due to the frosted layers, barrier between nutrients and external air is formed, so that the stability of the nutrients added in the soft sweets is facilitated.

A color wax fragrant clay and its production are disclosed. The process is carried out by taking refinery paraffin, palmic acid, mineral butter, ceresine wax and candle essence as raw materials, heating, dissolving, and mixed freezing to obtain final product. It costs low and has better quality.

The invention provides a defoaming agent for landfill leachate and a preparation method thereof. An organic matter which is synthesized by monounsaturated fatty acid, fatty diacid and alkylol amine is introduced and used as a foam elimination and inhibition synergist E and is compounded with glycerin polyether M and linear or branched fatty alcohol polyether N with the carbon atom number of 10 to 20, wherein the organic matter foam elimination and inhibition synergist E can be used for improving the dispersion effect of polyether, so that the polyether can be dispersed into a system better; meanwhile, the dosage of the monounsaturated fatty acid is improved in a synthesis process of the organic matter so that the foam inhibition effect of the organic matter is improved. The defoaming agent has a good foam elimination and inhibition effect in a landfill leachate treatment process; meanwhile, the dispersity of the defoaming agent in the landfill leachate is finally improved; in an application process, the blocking of a terminal filtering membrane is not caused and the treatment efficiency of the landfill leachate is greatly improved.

The invention provides an electrolytic manganese residue and shale sintered product and a production method thereof.
