Provided is a fluid mixture spray device which sprays a fluid mixture comprising air that contains minute wash water particles, thereby being capable of removing dust stuck to a coated surface, said dust containing carbon etc. For this purpose, the fluid mixture spray device (10) is equipped with a two-fluid mixing tank (11) that equalizes the pressure of air (1) which flows in with that of wash water (3A) containing detergent; an air passage (12) which is connected to the two-fluid mixing tank (11); a wash water passage (13A) which is connected to the two-fluid mixing tank (11); an ejector section (15) which connects the air passage (12) and the wash water passage (13A) to each other, and forms the wash water (3A) into minute wash water particles; and a spray nozzle (16) which sprays at high speed a fluid mixture (5) consisting of compressed air (1) and pure water (3) which turned into minute water particles. As a consequence of spraying at high speed the fluid mixture (5) containing the pure water (3) which turned into minute water particles, this pure water (3) which turned into minute water particles is destroyed, resulting in a small quantity of residual pollutants being removed from the coated surface.

The invention relates to cleaning equipment, in particular to cleaning equipment for plastic toys for children. The cleaning equipment for the plastic toys for the children is high in cleaning efficiency, and cleaning is thorough and can achieve a clean effect. The cleaning equipment for the plastic toys for the children comprises a bottom plate and the like. A support plate is connected to the right side of the top of the bottom plate.

The rotation device drives the plastic toys to rotate, thus the plastic toys are overturned, the plastic toys are cleaned efficiently by the cleaning device, clear water is driven by a washing device to spray on the surfaces of the plastic toys, so that cleaning efficiency is improved, the cleaning effect is enhanced, and the effects of high cleaning efficiency and thorough and clean cleaning are achieved.

The invention provides a plant tissue genome DNA extraction kit and a high-throughput extraction method. Using this kit, high-quality maize genomic DNA can be quickly extracted, and the extracted DNA can meet the requirements of general molecular marker detection and sequencing library construction. With the DNA extraction method of the present invention, high-quality and high-throughput DNA extraction is realized, and the efficiency of the entire DNA extraction process is greatly improved, and the DNA extraction cost is greatly reduced compared with the conventional extraction scheme. The entire process of DNA extraction from cleavage, purification to product collection can be completed by the instrument, with a high degree of automation, and the reagents used in the extraction are highly safe, which can avoid harm to the human body to the greatest extent.

The invention provides a novel artificial marble and manufacturing method thereof. The novel artificial marble comprises a body layer composed of a filling material and a resin adhesive material, a coating layer containing titanium dioxide or a mixed coating comprising titanium dioxide. The surface of the novel artificial marble has a titanium dioxide coating film or a coating containing titanium dioxide or the mixed coating comprising titanium dioxide, so that the artificial marble has a self-cleaning function, and can greatly reduce cost for maintaining clean when the artificial marble is used as a building material. Due to the excellent ultraviolet absorption function of titanium dioxide, decomposition of the component materials of the artificial marble can be effectively prevented; mechanical performance of the artificial marble can be maintained; and fractures / cracks can be prevented from appearance. The particles or powder of the main raw materials of the artificial marble are inorganic waste materials of buildings and livings and even waste materials of the artificial marble, thereby reducing cost, decreasing resource waste and protecting the environment.
