The invention discloses a phosphogypsum-based thermal insulating mortar containing expanded perlite, and belongs to the solid waste comprehensive utilization and building material technical fields. The thermal insulating mortar includes expanded perlite and a material A which is prepared from phosphogypsum, wherein the mass ratio is 1:8-17. The expanded perlite are used in large amounts, and the weight specific gravity of the expanded perlite is far greater than that of the material A prepared from the phosphogypsum, so that the phosphogypsum-based thermal insulating mortar has the characteristics of low thermal conductivity, good thermal insulating and sound insulating effects, energy saving, low production cost, and no toxicity and no pollution, and is convenient to achieve thermal isolation and sound insulation of the construction; and at the same time, the phosphogypsum-based thermal insulating mortar is subjected to product testing according to ''thermal insulating mortar for buildings'' (GB / T20473-2006) standards; and results comprise the packing density is less than 350 kg / m<3>, the compressive strength is greater than 0.4 MPa, and the radioactivity specific activity degree simultaneously meets related indicator requirements that an inner illumination index and an outer illumination index are both less than 1.0.

The invention provides oleanolic acid and a method for preparing the oleanolic acid by utilizing Chinese red dates. The method comprises the following steps: denucleating the Chinese red dates, and smashing, thus raw material particles are obtained, wherein the Chinese red dates are imperfect and dry; adding a solvent into the raw material particles to obtain a solution A, wherein the solvent is 80-95% ethyl alcohol, and the mass ratio of the solvent to the raw material particles is (10-18):1; carrying out microwave heating and leaching on the solution A, wherein the microwave power is 70-350W, and the microwave heating time is 90-150 seconds; filtering products after the microwave heating and leaching are carried out, thus a solution B is obtained; concentrating the solution B, removing the solvent, and adding distilled water, thus a solution C is obtained; adding a flocculating agent into the solution C, thus a sediment D is produced; and dissolving the sediment D with absolute ethyl alcohol, filtering, removing undissolved substances, concentrating, and removing the absolute ethyl alcohol, thus the oleanolic acid is obtained. In the invention, a microwave-assisted extraction method is adopted, and the process can be simplified; and, imperfect dry Chinese red dates are taken as raw materials, the raw materials are available, and the cost is low.

The invention relates to a swine hemoglobin enzymolysis and decoloration technology. The technology comprises the following steps of: performing centrifugal separation on swine blood to form blood corpuscles, adding water and quickly stirring; regulating pH value, and heating for boiling; adding a composite protease preparation, and performing enzymolysis at certain temperatures; performing enzyme inactivation after the enzymolysis, filtering, and performing spray drying on supernate to obtain gray white hemoglobin polypeptide; and drying precipitates to obtain a heme coarse product. By the technical scheme provided by the invention, hemoglobin polypeptide powder and the heme coarse product are obtained, wherein the hemoglobin polypeptide is a good animal protein source and is used as a feed additive to improve the digestion and absorption rates of protein; heme can be used as a chromogenic reagent in food industry and can be used as a pharmaceutical raw material in medical industry; and the hemoglobin polypeptide and the heme are products with high added values. The technical scheme has important significance of improving processing value-added capability of animal blood products, broadening comprehensive utilization ways, and promoting the technology upgrading of the whole industry.
