The invention discloses a preparation method of albumen antioxidant peptide. Egg albumen powder is used as main raw material, and the raw material is separated and purified through processes of thermal denaturation, enzymolysis,ultrafiltration, ion exchange, gel filtration, vacuum concentration and drying and the like to obtain the albumen antioxidant peptide with high activity. According to the invention, the albumen is subjected to enzymolysis with alkali protease, and albumen enzymolysis peptide with low molecular weight and high antioxidant activity is obtained through separation. In addition to reduction of antigenicity of albumen, improvement of functional characteristics and easiness for absorption, the product can also inhibit and eliminate free radicals as well as adjust and improve physiological functions, and can be applied to the research and development of medicines for preventing and treating chronic diseases. A new way for improving the additional value of the albumen, further processing eggs and application of eggs is developed, and the preparation method has wide market prospect.

The invention discloses a Trichoderma longibrachiatum strain (Trichodermallongibrachiatum GF-10) and its application. Its morphological characteristics: it grows rapidly on PDA, its back is colorless to yellow-green, and it can produce conidia when cultured at 28°C for 72 hours. Secondary branches of sporozoites are few, often protruding at right angles; phialides protrude directly from secondary branches, solitary, opposite, rarely whorled, gourd-shaped or flask-shaped, 5.3-11.6 μm long, wide 2.0-3.2 μm, conical shape of ultimate bottle stem; spores are gray-green or green, oval or oval, 3.4-6.6 μm long and 2.3-3.5 μm wide. The invention has strong tolerance to adverse environment, resistance to mutation, easy cultivation and preservation, and good effect of inhibiting tobacco black shank bacteria and tobacco red spot bacteria.

A technology for finishing the water-, oil-and dirt repellent polyester fabric includes such steps as preparing the finishing liquid from organofluorine composite nano material dispersed liquid and flexible-type self-crosslinking adhesive, dipping it in the finishing liquid for 0.5-1 min, squeezing, prebaking at 100-110 deg.C for 1-2 min, and baking at 130-180 deg.C for 3-5 min. Its advantages are excellent "three repelling" function, better durability and high washing resistance.

The invention discloses a boracic base core adsorbent and preparing method, which is characterized by the following: adopting glass, quartz or polystyrene inert ball to prepare the absorbent without adsorbing ability, possessing certain thickness for case and high-degree coordination selection adsorbing ability and active porous dielectric structure for carbohydrate with cis-form dihydroxy, nitrating crosslinking polystyrene ball of glass or quartz core through reducing and after-disposing, or nitrating crosslinking polystyrene ball of glass or quartz core incompletely through reducing and after-disposing.

The invention relates to a preparation method of separating and purifying silicon dioxide and cerous chloride from crystal stone wastes, belonging to the field of resource reuse, and is characterized by the following steps: 1) removing impurity: the crystal stone wastes is added with phosphoric acid as an impurity-removing agent and stirred to obtain a mixture of silicon dioxide and cerium oxide;and 2) separation: the mixture is added with concentrated hydrochloric acid as a separation agent, treated by water bath and filtration, the filtrate is evaporated and crystallized to fully precipitate cerous chloride heptahydrate crystals, which is oxidized to obtain cerium oxide crystals; the filter residues are dried at a temperature of <150 DEG C for 1 to 3 hours to obtain silicon dioxide. The preparation method achieves maximum utilization of resources of solid wastes, can transform trash into treasure and obtain phosphate by-products of high economic value and cerous chloride of high purity and high price, and also has advantages of low processing costs, highly pure target composition and significant economic benefits. The purification process follows the idea of clean production, energy saving and reducing emission so as to avoid the problem of environmental pollution.
