The invention discloses a protein product capable of fixing a target object and being cleared as required. The protein product comprises proteins (lysozyme, bovine serum albumin, whey albumin, insulin, alpha-lactalbumin, fibrinogen, ribonuclease A, cytochrome c, alpha-amylase, horse radish peroxidase, pepsase, myoglobin, collagen, keratin and the like), a protein modifier (a strong oxidant or a strong reducing agent), target fixtures (a coating, a pesticide, a chemical fertilizer, a cosmetic, a medicine and the like) According to the protein product, the target fixture is fixed on the surface of the target by using a protein membrane generated by phase transformation of the protein, so that the utilization rate of the target fixture is improved, and the problems of resource waste, environmental pollution and the like caused by loss of the target fixture are reduced. In addition, as the protein film is decomposed, the target fixture is also effectively removed. The protein serving as the main component is safe and environment-friendly, the biocompatibility is high, the preparation method is simple, and the method has a wide prospect in practical application.

The invention provides an inductance coupling apparatus used for exciting and maintaining plasma in a technical cavity. The inductance coupling apparatus comprises an inductance coupling coil arranged in the technical cavity, a radio frequency power supply connecting with the inductance coupling coil and a voltage regulating power supply. In a technical process, the voltage regulating power supply loads positive bias to the inductance coupling coil to reduce even eliminate negative self-bias near the inductance coupling coil, problems that the inductance coupling coil is consumed in the technical process, wafer pollution is generated and the like are avoided. The invention also provides plasma processing equipment applying the above inductance coupling apparatus.

The invention belongs to the field of utilization of non-traditional resources in the field of environmental protection and discloses a hot-recycling asphalt mixture containing non-traditional oil. The hot-recycling asphalt mixture is characterized by being prepared from a waste asphalt mixture, new aggregate, new asphalt and a non-traditional oil regeneration agent, wherein the waste asphalt mixture accounts for 30%-60% of the total mass of the waste asphalt mixture, the new aggregate, the new asphalt and the non-traditional oil regeneration agent, the new aggregate accounts for 38%-68% of the total mass of the waste asphalt mixture, the new aggregate, the new asphalt and the non-traditional oil regeneration agent, and the new asphalt accounts for 1%-2% of the total mass of the waste asphalt mixture, the new aggregate, the new asphalt and the non-traditional oil regeneration agent; the non-traditional oil regeneration agent accounts for 1%-3.5% of the mass of waste asphalt in the waste asphalt mixture. The implementing process of the mixture is simple, the regeneration effect is good, and the hot-recycling asphalt mixture is economical and environment-friendly.

A kind of natural concentrated dietary fiber and preparation method thereof, described natural concentrated dietary fiber is that the pine bark that is rich in dietary fiber is crushed and sieved, soaked in water, drains waste water after soaking, and then transfers the soaked pine bark To the reactor, add water to obtain the pine bark mixed liquid, carry out ultrasonic-assisted enzymolysis treatment, drain the liquid after enzymolysis, then insert the enzymolysis material into Lactobacillus plantarum HKB‑38 for fermentation, and ferment the fermented The material is subjected to high temperature and high pressure heat treatment, cooled and dried to obtain natural concentrated dietary fiber. The invention also includes a preparation method of natural concentrated dietary fiber. The invention selects pine bark with low price and abundant resources as the production raw material, greatly reduces the production cost, makes full use of resources and creates high added value. The invention significantly improves the purity of the dietary fiber and the swelling and water holding capacity of the fiber product. Experiments have proved that in the concentrated dietary fiber of the present invention, the crude fiber content is ≥ 60%, the neutral detergent fiber (NDF) content is ≥ 86%, the acid detergent fiber (ADF) content is ≥ 70%, the product swelling property is ≥ 5.0mL / g, and the water holding capacity ≥5.0g / g.

The invention discloses a method for extracting lignin by using a ternary deep eutectic solvent. The method comprises the steps of: mixing and reacting the raw material with a ternary deep eutectic solvent, cooling to room temperature after the reaction is completed, and obtaining a reaction product, adding the reaction product to absolute ethanol and stirring, washing with ethanol, filtering, concentrating, adding water, and standing , to obtain a precipitate containing lignin, filter, and dry to obtain lignin. The present invention provides a method for extracting lignin from straw by using a ternary deep eutectic solvent, which improves the extraction efficiency of lignin more effectively compared with a binary deep eutectic solvent, and achieves the maximum extraction efficiency within 4 hours The lignin purity is 84±1%, and the purity of the obtained lignin is relatively high, with the highest purity reaching 83%. The deep eutectic solvent and absolute ethanol can be recycled and reused during the extraction process. Problems such as pretreatment cost and environmental pollution are in line with the concept of green and environmental protection development.
