The invention discloses a liquid storage tank capable of preventing liquid from sloshing and aims at solving the problem that a liquid storage tank in the prior art is poor in anti-sloshing effect. The liquid storage tank capable of preventing the liquid from sloshing comprises a main liquid storage tank body, two sealing heads, a longitudinal shaft, n anti-sloshing plates and n+1 blade anti-sloshing devices, and n is a natural number greater than or equal to one. The main liquid storage tank body is sequentially welded to the two sealing heads located at the front end and the back end of the main liquid storage tank body to form a liquid storage tank body. The longitudinal shaft is installed in the liquid storage tank body. The two ends of the longitudinal shaft are welded to the centers of the two sealing heads. The n anti-sloshing plates are installed on the longitudinal shaft in a sleeving mode. The peripheries of the anti-sloshing plates are in welded connection with the inner wall of the main liquid storage tank body. The n-1 blade anti-sloshing devices are installed on the longitudinal shaft between the two anti-sloshing plates in a sleeving mode through blade anti-sloshing device shaft sleeves. Two blade anti-sloshing devices are installed in the positions, between the sealing heads and the anti-sloshing plates and between the anti-sloshing plates and the sealing heads, of the longitudinal shaft in a sleeving mode through the blade anti-sloshing device shaft sleeves. The blade anti-sloshing device shaft sleeves are rotationally connected with the longitudinal shaft. The other ends of the n+1 blade anti-sloshing devices are welded to the inner wall of the main liquid storage tank body through four tank body spring seats.

The invention relates to a thermoelectric power generation sheet.

The invention provides the thermoelectric power generation sheet which can be automatically disconnected during overload and can be automatically connected after normality and is provided with the overload protection power supply terminal, and the problem that a traditional thermoelectric power generation sheet cannot be automatically powered off after overload and cannot be automatically recovered after normality is solved.

The invention relates to a highly-tenacious cut-resistant core spun yarn. The highly-tenacious cut-resistant core spun yarn is mostly composed of a shaft core part and a wrapping part. A second core yarn of the shat core part has better friction coefficient due to a jumping fiber surface in the surface layer. During the process of making into yarns, first and second core yarns are mutually and closely attached to each other so that tensile strength is increased. The yarn is not easy to break. Effects of effectively increasing production efficiency and improving quality are obtained. The better friction coefficient of the second core yarn enables the wrapping part to be closely wound around the first and second core yarns. No separation occurs. Second core yarns of the shaft core part and short fibers of the wrapping part have highly-tenacious and good mechanical strength. The structure of the core spun yarn has excellent cut-resistant and anti-tensile strength so that a finished product made by the structure of the core spun yarn is puncture-proof, abrasion-resistant and cutting-resistant. Therefore, the highly-tenacious cut-resistant core spun yarn can be made into a highly-progressive product.

The invention discloses an adhesive for corrugated paper and a processing method thereof. The adhesive comprises the following raw materials in parts by mass: 10-15 parts of oxidized starch, 15-20 parts of polyvinyl alcohol, 1-3 parts of cooked tung oil, 5-10 parts of silicon resin, 3-5 parts of silicon dioxide, 1-2 parts of isocyanate, 3-6 parts of lactobionic acid, 2-4 parts of magnesium carbonate and 1-2 parts of sodium hydroxide. The processing method comprises the following steps: 1, according to the mass parts, adding the oxidized starch, the polyvinyl alcohol, the magnesium carbonate and the sodium hydroxide into a reaction kettle; 2, and adding the silicon dioxide, the isocyanate and the lactobionic acid into the reaction kettle according to the mass parts; 3) adding the cooked tung oil and the silicon resin into the reaction kettle in parts by mass; 4, cooling the mixture obtained in the step 3 to 10-30 DEG C at normal temperature to obtain the corrugated paper adhesive.
