A method for preparing a high oil content O / W film-forming base preparation

PendingCN122502947AUniform thicknessAdequate adsorption
This invention discloses a method for preparing a high-oil-content O / W film-forming formulation, comprising the following steps: Step 1, raw material pretreatment and screening; Step 2, preparation of the oil phase component; Step 3, preparation of the aqueous phase component; Step 4, primary pre-emulsification treatment; Step 5, high-pressure homogenization and fine emulsification; Step 6, compounding of film-forming aids and system conditioning; Step 7, vacuum degassing treatment; Step 8, low-temperature curing and stabilization treatment; Step 9, molding, coating and curing film formation; Step 10, post-treatment and quality inspection. This invention employs nonionic and anionic compound emulsification, combined with multi-stage high-pressure homogenization and interface modifier optimization, to achieve uniform oil droplet size distribution and effectively suppress stratification, demulsification, and flocculation phenomena under high oil-phase ratios. Through a low-temperature segmented curing process, the emulsifier is fully adsorbed and arranged at the oil-water interface, enhancing the strength and toughness of the interfacial film, while simultaneously improving the compatibility between the film-forming agent and the emulsification system.

Preparation device and method of micro-modified atmosphere fruit and vegetable preservation film

PendingCN122323434AImprove breathabilityreduce permeabilityPtru catalystCatalytic function
This invention discloses a device and method for preparing a micro-atmosphere modified atmosphere (MAA) fruit and vegetable preservation film. The device includes a forming cylinder assembly, a feeding and coating assembly, a dust generation and settling assembly, an air-cooling device, and a film hoisting and collecting assembly. The forming cylinder assembly includes a rotatable self-heating forming cylinder. The feeding and coating assembly coats the film-forming liquid onto the upper left surface of the self-heating forming cylinder. The dust generation and settling assembly settles nano-antibacterial catalyst dust onto the film surface on the self-heating forming cylinder. The air-cooling device cools and shapes the film surface on the lower right side of the self-heating forming cylinder. The film hoisting and collecting assembly collects the formed film. This invention utilizes the time window before the film completely solidifies to load nano-catalytic functional powders, allowing the powders to adhere firmly to the film surface, increasing the contact area between the catalytic powders and oxygen, improving catalytic efficiency, and reducing the risk of catalytic powder migration.

A cross-scene spatial intelligent semantic topology generation method and system

ActiveCN121598648BStructural continuitysmooth structureGeometric CADDesign optimisation/simulationAlgorithmSpatial intelligence
The application relates to the field of space intelligence, and provides a cross-scene space intelligent semantic topology generation method and system. In the process of constructing a cross-scene space semantic topology, a transition region modeling mechanism with a transition node as a core is introduced, regions where mutations in geometric structures, semantic attributes and topological scales simultaneously occur between different space scenes are identified, expanded and processed as independent objects, and the problem of semantic rupture, topological distortion and space incoherence caused by simple splicing at the scene boundary level in the prior art is avoided. The transition node is structurally expanded based on a topological connection relationship, a transition region reflecting the connectivity of different space scenes is constructed, and semantic transition consistency constraints and topological structure deformation compensation are implemented in the transition region. In addition, the application combines a multi-scale topological self-adaptive adjustment mechanism, so that the cross-scene semantic topology can dynamically adjust node granularity and topological levels under different space scales.
