The invention relates to a production technology of russula vinosa lindblad powder, and belongs to the field of production and processing of mushrooms. The production technology comprises five steps of performing cleaning, performing heating drying, lowering the temperature, performing ultrafine crushing, and performing sterilization and bagging, wherein the heating drying process is performed through control of procedures; and the ultrafine crushing is performed in the manner that the dried russula vinosa lindblad is transferred to an airflow type ultrafine crusher, airflows are used for crushing the russula vinosa lindblad, the air pressure is 0.2-0.4Mpa, and the ratio of air to solid is (2 to 1) to (3 to 1), so that the particle size of the obtained russula vinosa lindblad powder achieves 80[mu]m or below. Nutrient elements of the russula vinosa lindblad are reserved to the maximum extent, and the prepared russula vinosa lindblad powder can be rapidly prepared into various beverages and can also be added to various food materials, so that the nutrients of foods are increased. The russula vinosa lindblad powder has the efficacy of nourishing yin, invigorating the kidney, invigorating the brain and keeping young. The russula vinosa lindblad powder made by the method is long in storage time, convenient to transport and convenient to sell, and the business value of the russula vinosa lindblad is increased.

A bypass baffle for limestone wet flue gas desulfurization, comprising an air outlet, the inside of the air outlet is fixedly installed with a partition, the right side of the air outlet is movably installed with a rotating shaft, and the right end of the rotating shaft is hinged with a rotating blade. The right side of the leaf is movably installed with a fixed plate, and the outer surface of the fixed plate is provided with an arc groove. The inside of the arc groove is slidably installed with a fixed rod. There are curved plates. Through the combined use of the arc plate and the scraper hook, the dirt formed between the air outlet and the rotor blade can be effectively scraped off, ensuring that during the desulfurization process, there will be no easy fouling between the air outlet and the rotor blade. In this way, it is ensured that the rotor blade and the air outlet can always be tightly closed when they are opened and closed without gaps, which further ensures that the sealing in the boiler is good and will not cause negative pressure in the furnace of the boiler. Ease of use.

The invention relates to the technical field of PCB manufacturing, in particular to a manufacturing method of a PCB with a base copper-free metallized blind hole. The manufacturing method comprises the following steps: firstly manufacturing a metallized blind hole, then performing pattern plating, adopting a depth controlled milling manner to remove a copper layer at the bottom of the hole before outer layer etching, and then etching the copper edge remaining at the bottom of the metallized blind hole through the outer layer etching, so that the milled edge is smooth, the problems that the copper edge remaining at the bottom of the base copper-free metallized blind hole is large in area and coarse can be avoided, and the quality of the base copper-free metallized blind hole is greatly improved; setting the perpendicular distance between the milled edge and the wall of the metallized blind hole to be 0.01-0.02 mm, and enabling the milled edge after outer layer etching to be basically flush with the hole wall; setting the depth controlled milling to be 0.1-0.11 mm deeper than the metallized blind hole, so as to ensure that the copper layer at the bottom of the hole is completely removed, and no influence is generated due to nonuniformity of the copper layer.

The invention provides a self-adaptive circulating lubricating system for a sliding bearing and belongs to the technical field of bearing lubricating systems. The self-adaptive circulating lubricating system is characterized by comprising a filter (2), a pressure-cutting oil supply device (4) and a heat exchanger (6); the liquid outlet end of the filter (2) communicates with the liquid inlet end of the pressure-cutting oil supply device (4), and the liquid outlet end of the pressure-cutting oil supply device (4) communicates with the liquid inlet end of the heat exchanger (6); the sliding bearing (1) is provided with an oil inlet hole and an oil outlet hole, the liquid inlet end of the filter (2) communicates with the oil outlet hole of the sliding bearing (1), and the liquid outlet end of the heat exchanger (6) communicates with the oil inlet hole of the sliding bearing (1); and a rotary shaft for mounting the sliding bearing (1) is connected with the power input end of the pressure-cutting oil supply device (4).
