The utility model relates to a production device of trifluoromethylpyrimidine. The production device comprises a heat exchange cylinder, wherein the heat exchange cylinder comprises a lower ring body which is fixedly connected with a reaction kettle through a plurality of first connecting ends and a plurality of second connecting ends which are distributed at intervals around the circumference. And a multi-step through hole is formed on the reaction kettle and at the position where the two connecting ends are arranged. And a threaded counter bore I which is correspondingly matched with the multi-step through hole and is internally provided with a convex column is formed in the lower ring body. The first connecting end comprises a first stud with a shaft hole. The second connecting end comprises a second stud. An external thread surface and an axial convex ring are respectively formed at one end of each stud; the external thread surfaces are matched with the threaded counter bores I; and the convex columns are inserted into the axial convex rings. And a through hole structure capable of communicating the ring cavity on the lower ring body with the shaft hole is formed on the convex column correspondingly matched with the first stud. And a sealing structure is arranged between the opposite circumferential surfaces of the stud and the multi-step through hole. The assembly and disassembly operation between the lower part of the heat exchange cylinder and the reaction kettle can be quickly realized, and the efficiency of the assembly and disassembly operation is favorably improved.

The utility model relates to the technical field of cables, and discloses a die for producing a low-temperature radio frequency cable, which comprises a lower die, bayonets are arranged on one side of the lower die, the bayonets are symmetrically arranged, rectangular sliding chutes are arranged on one side of the lower die, and the rectangular sliding chutes are circumferentially arranged at equal intervals. Under the guidance of the guide column, the upper mold and the lower mold can be quickly and accurately matched together without a tedious alignment process, the molds can be quickly fixed by rotating the arc-shaped clamping rod I and the arc-shaped clamping rod II, and similarly, the arc-shaped clamping rods can be reset only by simple operation during disassembly, so that the molds are released, and the production efficiency is improved. Under the action of the balancing weight, when the clamping part is not clamped with the connecting port any more, the first arc-shaped clamping rod and the second arc-shaped clamping rod can automatically rotate and reset, manual intervention is not needed, and the design of the limiting block ensures that the arc-shaped clamping rods can be kept at the stable position after resetting, and accidental loosening is avoided.

The application provides a multi-layer penetration controlled-release acid preparation and a preparation method thereof, and belongs to the field of cosmetics. The preparation is composed of Aspergillus oryzae fermentation substrate freeze-dried powder, composite alpha-hydroxy acid, salicylic acid, poloxamer 407, polyhydric alcohol and non-ionic surfactant. The freeze-dried powder is obtained by co-fermenting olea europaea leaves and curcuma and refining through ultrafiltration. A temperature-sensitive phase change system is constructed by using poloxamer, so that the product is changed from a liquid state to a gel state at body temperature, and the synergistic controlled release of acid components and bioactive substances is realized. The preparation process adopts low-temperature swelling and vacuum freeze-drying technology, so that the stability of the system and the efficiency of the active substances are ensured. The application significantly reduces the irritation of high-concentration acid, improves the black suppression and repair effect, and is suitable for precise improvement of hyperpigmentation problems such as chloasma.
