The invention discloses a polyester alloy composition for improving high-temperature welding performance and application thereof, and relates to the technical field of high polymer materials, the polyester alloy composition is prepared from the following components by weight: 5-30 parts of polyarylester, 30-70 parts of polycarbonate, 10-30 parts of a styrene-butadiene-acrylonitrile copolymer, 2-6 parts of a flexibilizer, and 0.5-2 parts of a heat stabilizer. 1-2 parts of a coloring agent, 0.4-1 part of an antioxidant, 0.2-0.5 part of a lubricant and 0.1-0.5 part of an ester exchange inhibitor. The polyester alloy composition for improving the high-temperature welding performance provided by the invention has the characteristics of high temperature resistance, high welding strength and stable size; therefore, the alloy material is particularly suitable for being applied to the field with the requirements for high strength and high size precision of hot plate welding, for example, the hot plate welding of main and auxiliary instrument panel bodies and side plates of automobiles has a good application effect.

The invention relates to a detachable sealed vacuum room solar-energy heat collecting exchanging device. The invention mainly comprises a detachable sealed vacuum heat collecting room formed by a glass cover plate with reflective-reducing film, a cover plate and high-efficiency solar-energy collecting plate as dual-layer walls, a thermal-insulated heat exchanging room welded at the back of heat collecting plate, the tubes of medium and relative elements. The invention is characterized in the combination between detachable sealed solar-energy heat collecting room and the thermal-insulted heat exchanging room. The invention can improve the heat collecting efficiency of solar energy.

The invention discloses a multifunctional stir-frying herbal medicine roaster for traditional Chinese medicine processing, and belongs to the technical field of traditional Chinese medicine processing. The multifunctional stir-frying herbal medicine roaster comprises a shell and a removing box, the shell is obliquely mounted on the upper surface of the removing box through an adjusting assembly, a heat conduction oil heating furnace is arranged on one side of the removing box, and a first mounting plate is fixed to one end of the shell; and a gear motor is mounted at the bottom of the first mounting plate, a material opening is formed in the other end of the shell, a baffle is mounted in the material opening, an exhaust pipe is mounted on the baffle, an outer cylinder is mounted in the shell, and an inner cylinder is mounted in the outer cylinder. By arranging the heat-conducting oil heating furnace and an oil cavity, in cooperation with conveying of heat-conducting oil through an oil inlet pipe and an oil outlet pipe, a traditional electric heating plate heating mode is changed into a heat-conducting oil mode to heat traditional Chinese medicine, on one hand, the failure rate of the device is reduced, the later maintenance cost is reduced, on the other hand, the heating uniformity of the heat-conducting oil is high, and the medicine property of the stir-fried medicinal materials can be improved.
