The invention discloses an energy-saving efficient plastic granulator, a feeding screw rod is rotationally arranged in a feed barrel, a scraper plate is rotationally arranged in a granulation extrusion cavity, a scraping block is arranged on the excircle of the scraper plate, the scraping block is closely attached to the inner cylinder wall of an extrusion die cylinder, the cylinder wall of the extrusion die cylinder is provided with extrusion holes, and a rotational cut-off tool is arranged on the outer cylinder wall of the extrusion die cylinder; the energy-saving efficient plastic granulator is characterized in that: the inner cylinder wall of the feed barrel is provided with a plurality of vertical ribs, the vertical ribs pass through, from up to down, the whole feed cylinder height, the top circle of the vertical ribs is matched with the excircle of the feeding screw rod, adjacent vertical ribs, and the inner cylinder wall of the feed barrel and the excircle of the feeding screw rod enclose a space to form an inner air circulation channel of the feed barrel. The energy-saving efficient plastic granulator uses the scraping block to grind a material to produce heat to melt the material for plastic granulation, the energy-saving efficient plastic granulator can always smoothly exhaust in the working process, and the unique scraper plate is designed to avoid local overheating of the material so as to avoid obstruction of heat transfer, so that automatic control of blanking and feeding can be achieved, and the entire normal high-speed granulation process and high granulation quality can be ensured.

The invention discloses a leadless gamma ray shield flexible composite material and a preparation method thereof. The method comprises the following steps: aqueous polyurethane and a proper amount ofa thickening agent I are mixed, a mixture is dispersed at a low speed by a dispersing sand mill, a gamma ray screener is slowly added during a dispersing process, after dispersion, a few of a thickening agent II, an antifoaming agent, a dispersant, and a coupling agent are added in order; the dispersing speed is adjusted to a rapid state, the materials are dispersed for 20 min, a few of the antifoaming agent is added, and then rapid dispersion is kept for 10 min; and ultrasonic dispersion is performed on the above mixture for 20 min; vacuum-pumping treatment is performed on the above mixture to remove bubbles, and a paint is obtained; fabric base cloth is fixed on a pin frame of a coating machine, the above prepared paint is employed for coating treatment on the base cloth, the coating fabric is aired for 2 hours at room temperature, then the fabric is placed in a baking oven and the fabric is dried for 1 hour at the temperature of 60 DEG C, and the coating fabric is aired for 24 hoursat room temperature to obtain the leadless gamma ray shield flexible composite material.

The invention discloses a prevention and treatment method for Oides duporti. According to the invention, through circulating application of a pesticidal fertilizer in November to December, the incubation rate of Oides duporti ova and the pupation rate of Oides duporti pupae are reduced, and the initial population number of the Oides duporti in a field is decreased; and by adoption of a hot smog method in a full outbreak period in March to April and July to August, pesticide smog with high concentration and high density is utilized for long-term enshrouding treatment, so Oides duporti larvae and adult Oides duporti are difficult to hide, wherein the prevention and treatment effects with 95% or above can be reached through treatment for two times.

The invention relates to a sub-normal-temperature potato preservation method. The method includes steps: (1) post-harvest processing, namely performing sulfur fumigation for disinfection and clearing of a crypt to keep a low temperature before storage; (2) potato surface treatment; (3) storage environment control; (4) pre-marketing treatment. By means of two-stage mildew-proof treatment, a potato bud control mildew-proof complex agent I is adopted and effective in control of potato germination and mildewing, and the bud control rate and the mildew-proof rate are 31% and 15% of those of a contrast respectively; at a second stage, a preservative agent II is adopted and also has antiseptic and sterilization efficacies.

The invention relates to a treatment method for excess sodium sand in chemical reactions. The invention discloses a method for deactivating active sodium sand. Under the protection of inert gas, liquid paraffin is added to the active sodium system to be treated, and water is added to directly deactivate the active sodium. After deactivation, layers are separated, and the water layer is neutralized and then discharged. The liquid paraffin used in the present invention is common industrial liquid paraffin, which has a high boiling point and is not prone to bumping; it has a large specific heat and is a good dispersion medium, which can effectively disperse active sodium and isolate it from the air; the amount of liquid paraffin is reasonable, Moreover, it can be recycled, and the cost is low; the operation is simple and safe; after the treatment, the water layer can be directly discharged, which is environmentally friendly, and the liquid paraffin is recycled for reuse. Effect.

The invention discloses a convex-concave mirror light concentrating type water tank power generation device and relates to the technical field of water tank power generation. The convex-concave mirrorlight concentrating type water tank power generation device comprises a base, a first fixing plate and a water pump; a first fixing ring, a second fixing ring and a sliding plate are fixed to one surface of the base from outside to inside in sequence; the sliding plate is located in the cavity formed by the first fixing ring and the second fixing ring; a slotted hole is formed in the surface of the base, and a sliding block is fixed to the surface of the first fixing plate. According to the convex-concave mirror light concentrating type water tank power generation device, through the cooperation of a concave mirror and a convex lens, light can be effectively concentrated, and therefore the utilization rate of the light can be improved, and the device is enabled to generate electricity faster and more effectively; a second gear is driven to rotate by a motor and matched with a sliding block on a first fixing block to slide along the sliding plate arranged between the first fixing ringand the second fixing ring, so that the concave mirror of the device can be timely changed with the change of illumination, the device can generate electricity better and make full use of the illumination.

A modified high density brine for use in subterranean drilling and completion operations. The modified high density brine includes the addition of high density particle addition that can optionally be surface-modified. The resultant modified high density brine eliminates the need for toxic, corrosive, and costly ZrBr2 additions or other ionic additives to boost the density of the modified high density brine to 15-17 lbs. / gallon or greater.
