This utility model discloses a vacuum coating apparatus, comprising: a vacuum system including a vacuum chamber; a winding system disposed in the vacuum chamber for conveying a base film, comprising at least two cooling rollers arranged along a first horizontal direction, with an installation gap formed between adjacent cooling rollers; an evaporation source system disposed in the vacuum chamber, comprising evaporation sources located below the cooling rollers and corresponding to each cooling roller; and at least one baffle mechanism disposed in the installation gaps, corresponding to each installation gap, to prevent vapor crosstalk between adjacent evaporation sources; wherein the bottom height of the baffle mechanism is not higher than the top height of the evaporation source, and the top height of the baffle mechanism is not lower than the bottom height of the cooling rollers. This utility model, employing the above structure, can avoid mutual interference of vapors at adjacent cooling rollers, improving coating quality and subsequent cleaning of the vacuum chamber.

This invention discloses a multi-head combination scale for nut processing, comprising a combination scale, a transmission device, a separating device, a converging device, and a motor. The motor is detachably mounted on the top surface of the transmission device, driving a rotating component on the transmission device to perform rotational motion. The transmission device and the separating device are detachably mounted on the outside of the combination scale. This multi-head combination scale for nut processing, by setting a rotary sieving device on the multi-head combination scale, achieves vibration filtering of impurities and accurate weighing of nut products, effectively separating impurities from the target product. This ensures the uniformity and consistency of material composition in subsequent weighing processes, thereby improving the accuracy of weight detection. This not only helps to ensure the stability of packaged weight and reduce the error rate, but also improves the purity of the final product, providing consumers with products with more accurate net weight, and thus enhancing product quality reliability and brand reputation.

The invention discloses a compound water-based working solution for cleaning and passivating the inner wall of a stainless steel pipeline and a use method thereof. The working solution is prepared by compounding an organic acid complexing agent, a fluorine-containing inorganic acid dissolving agent, an oxidizing inorganic acid passivating agent, a nitrogen-containing heterocyclic metal corrosion inhibitor, an anionic surfactant and water. The use method comprises the following steps: carrying out alkaline pretreatment and flushing on the stainless steel pipeline system; the preheated working solution is pumped into a system to be circularly cleaned and passivated; and finally, neutralizing and finally washing. Through the synergistic effect of all the components, powerful rust removal and high-quality passivation are integrated into one step, three kinds of stubborn red rust can be thoroughly removed, meanwhile, a stainless steel substrate is effectively protected against over corrosion, the treated surface keeps the original silvery white luster and smoothness of metal, a compact passivation film is formed, the water quality of a system is recovered quickly, and the service life of the system is prolonged. The method is suitable for regeneration maintenance of old purified water systems.
