Provided are a synthetic industrial gear oil with a water-holding property and a preparation method therefor. The method comprises, with the total amount of the water soluble polyether being 100 parts, taking, in parts by weight, 20-30% of the total amount of a water soluble polyether and adding same to a product kettle and preheating same to 75-90ºC; metering an anti-friction and anti-rust additive and a copper corrosion inhibitor into the product kettle, and stirring same at a constant temperature for 25-35 min, until the anti-friction and anti-rust additive and the copper corrosion inhibitor are dissolved completely; and metering and pumping the remaining water soluble polyether into the product kettle, successively metering a high temperature antioxidant, an extreme pressure anti-wear additive, a chlorinated paraffin hydrolysis inhibitor, a hydrogen ion capturing agent and a defoaming agent into the product kettle, and stirring same uniformly to obtain the industrial gear oil with a water-holding property. The present invention has a good safety in use, good anti-friction and anti-wear properties, an excellent water water-holding capacity, a strong corrosion resistance, excellent oxidation stability and thermal stability, and energy-saving and emission reduction, and is especially suitable for lubrication of the reduction gear box when working in a water vapor environment.

The invention relates to medical health-care equipment, and discloses a moxa-moxibustion de-ashing fire extinguisher. The moxa-moxibustion de-ashing fire extinguisher is provided with a box body and a box cover, and is characterized in that the box body is internally provided with a horizontally-arranged de-ashing net in a suspending manner, wherein the de-ashing net is provided with an outer frame, the outer frame is provided with a plurality of longitudinal reinforcing ribs which form the de-ashing net together with a plurality of de-ashing steel wire strips which are transversely and uniformly arranged, the distance between every two de-ashing steel wire strips is 10mm, and a plurality of semicircular concaves are formed by bending on each steel wire strip, so that a plurality of longitudinal de-ashing groove structures are formed on the de-ashing net; two or more of the semicircular concaves on the same steel wire strip are different in radius, and the radius of each semicircular concave is set corresponding to a kind of moxa-moxibustion; the box body is also internally provided with an end plug for clamping the moxa-moxibustion; according to the moxa-moxibustion de-ashing fire extinguisher, the problems that an existing moxa-moxibustion extinguishing method and device cannot thoroughly extinguish fire and are not safe are solved, and the moxa-moxibustion de-ashing fire extinguisher can be widely used in places such as a family, a moxa-moxibustion shop, a beauty parlor, an institute of traditional Chinese medicine and a health club.

The invention relates to a cursor displayed float-type liquidometer. A float chamber of the cursor displayed float-type liquidometer is made of non-ferromagnetic materials, a float is a hollow ball-shaped float made of ferromagnetic materials, and a graduation ruler is installed outside the float chamber; a cursor comprises a cylindrical magnetic steel with a central hole, a short shaft, a connection rod and a balancing weight, wherein the central hole of the magnetic steel is horizontally located on the axis of the magnetic steel, and magnetic poles of the magnetic steel are distributed along the axial direction or located on the radial inner and outer surfaces of the magnetic steel; the short shaft penetrates through the central hole of the magnetic steel to be fixedly installed, and the connection rod is hinged to the short shaft and capable of rotating around the short shaft; the balancing weight is fixedly connected with the lower end of the connection rod, and the center of gravity of the cursor is guaranteed to be located on the medial axis of the cursor and below the horizontal central line of the magnetic steel; and the outer wall of the float chamber is provided with a plane which is parallel to the axis of the float chamber, and the magnetic steel is in line contact with the plane and rolls on the plane along the axial direction of the float chamber. The cursor displayed float-type liquidometer uses the cursor to replace a buoy and is simple in structure, easy to manufacture, reliable in using, cost-saving and wide in application range.

The invention discloses a flame-resistant carbon-fiber electrothermal paper and a preparation method thereof. The flame-resistant carbon-fiber electrothermal paper is prepared from the following raw materials by weight: 70 to 80 parts of a carbon fiber, 50 to 60 parts of wood pulp, 3 to 4 parts of gelatin, 1 to 2 parts of polyvinyl alcohol, 2 to 3 parts of lignin, 1 to 2 parts of a cross-linking agent TAC, 2 to 3 parts of polyvinylpyrrolidone, 1 to 2 parts of borax, 12 to 13 parts of aluminum hydroxide, 1 to 2 parts of ammonium persulfate, 1 to 2 parts of grape seed oil and 3 to 4 parts of modified mica powder. According to the invention, aluminum hydroxide is added into a formula for the raw materials and has good flame retardation performance, so the electrothermal paper prepared in the invention is safe to use and does not cause a fire hazard; the integral carbon fiber in the carbon-fiber paper is uniformly dispersed, and carbon-fiber paper has good breaking resistance, is hard to tear and damage and can be conveniently processed into planar heat-generating bodies according to different temperature requirements.
