The application provides a production method of high-corrosion-resistance and high-strength galvanized steel strand, relates to the technical field of hot-dip plating, and comprises the following steps: collecting hot-dip plating related characteristic parameters and setting basic hot-dip plating time; pre-processing the hot-dip plating related characteristic parameters and outputting a hot-dip plating calibration coefficient; establishing a coupling formula and obtaining a hot-dip plating calibration time; collecting strength interference characteristic parameters; based on the collected strength interference characteristic parameters and the obtained actual hot-dip plating required time, calculating a tensile strength prediction score of the produced galvanized steel strand, and determining the eligibility of the galvanized steel strand prepared under the current working condition parameters. The application calculates a most suitable galvanizing time, ensures that the zinc layer is fully penetrated, and avoids excessive reaction to cause the steel strand to be brittle. Meanwhile, the application can predict whether the tensile strength of the finished product is qualified before production, realizes dynamic optimization, early warning and self-learning in the whole process, and effectively reduces the waste product rate.

The application discloses a drainage bag with an antibacterial functional layer and a preparation process thereof, and relates to the technical field of medical materials, and comprises the following steps: adding modified montmorillonite into N, N'-dimethylacetamide, uniformly mixing through ultrasonic, adding a polyurethane film, ultrasonic immersion for 60-120 min, drying, and obtaining a drainage bag substrate; adding polylactic acid into N, N-dimethylformamide, uniformly stirring and mixing, adding modified nano zinc oxide, uniformly mixing through ultrasonic, and then performing electrospinning to obtain an antibacterial coating fiber film; placing the antibacterial coating fiber film on the inner side surface of the drainage bag substrate, high-frequency heat sealing, assembling, and obtaining the drainage bag.

This application relates to the field of plastic film molding and processing, and discloses a multilayer co-extruded film for winter sheds in aquaculture and its preparation method. It is produced by co-extrusion and blown film blowing of an outer layer, a first adhesive layer, a middle layer, a second adhesive layer, and an inner layer. The inner layer contains the following weight percentages: 63-71% composite metallocene low-density polyethylene, 10-20% low-density polyethylene, 5-10% modified toughening masterbatch, 5-8% anti-fogging and anti-dripping agent, 0.5-1% UV stabilizer, 0.5-1% UV absorber, 0.2-0.5% antioxidant, and 2.5-5% processing aid. The modified toughening masterbatch contains EPDM rubber, and the anti-fogging and anti-dripping agent is obtained by melt extrusion and granulation of styrene-octene-glycidyl methacrylate copolymer, vinyl elastomer, acrylic modified silicone, long-chain carboxylic acid ester polyoxyethylene, and pentaerythritol stearate. Advantages: good anti-dripping, puncture and tear strength, good low-temperature toughness, and not easily cracked or damaged.
