The invention discloses a production process of a protective film for electronic equipment. The production process of the protective film for the electronic equipment comprises the following steps: S1, pretreatment and functional coating of a base film; s2, performing multifunctional precision coating; s3, cutting and packaging in an ultra-clean environment; the electronic equipment protective film comprises a release film, an electrostatic adsorption layer, a base film, an automatic repair layer and a surface coating functional layer which are sequentially stacked, the step S2 further comprises the following steps that S21, the coating structure is subjected to one-time extrusion molding from top to bottom; s22, a curing process is conducted, specifically, a UV-LED excimer lamp two-stage curing system is adopted, and after coating is completed, a product passes through a UV-LED curing section firstly; and then deep curing is carried out through a 172nm excimer lamp. According to the production process of the protective film for the electronic equipment, high-purity aromatic TPU with the thickness of 0.2 mm is adopted, and excellent anti-falling and anti-impact basic protection is provided for a screen due to the inherent high toughness, elasticity and impact resistance of the high-purity aromatic TPU.

This utility model relates to the technical field of building material test specimen manufacturing equipment, and in particular to a mixer for making test specimens of construction waste roadbed filling soil. It includes a receiving device, a discharge pipe, material baffles, baffles, a centrifuge, centrifugal baffles, and a distribution chamber. The discharge pipe is a square tube with an expanded distribution chamber at its bottom. The receiving device is installed at the top of the discharge pipe. Multiple material baffles are installed inside the discharge pipe; each baffle is a concave chute or a flat chute with side baffles. The lower end of the chute's working surface converges inward. A baffle is located at the bottom of the material baffles, at the center of the connection between the discharge pipe and the distribution chamber. The centrifuge is installed inside the distribution chamber, below the baffles. The centrifugal baffles have at least two layers, surrounding the centrifuge and installed within the distribution chamber. This mixer has the function of real-time uniform mixing and distribution without material retention during the process, and is suitable for making test specimens with continuously changing material ratios.

The application belongs to the technical field of textile fabric function modification, and discloses a wear-resistant and ultraviolet-resistant fabric and a preparation method thereof.The fabric is formed by interweaving warp yarns and weft yarns to form a fabric base material, the fiber surface of the fabric base material is covalently grafted with a wear-resistant and ultraviolet-resistant composite functional layer, the warp yarns are super high molecular weight polyethylene and graphene composite modified fibers, the weft yarns are core-spun yarns with high-strength polyester fibers as the core layer and cotton fibers as the skin layer, and the wear-resistant and ultraviolet-resistant composite functional layer is a resin layer formed by covalent grafting and crosslinking of graphene core-zinc oxide shell nanoparticles modified by gamma-methacryloxypropyl trimethoxysilane and an anionic waterborne polyurethane containing an unsaturated carbon-carbon double bond at the end.The application effectively improves the bonding force of the functional layer and the base material, enhances the wash-resistant stability of the fabric function, and takes into account the wear-resistant and ultraviolet-resistant performance and the wearing comfort of the fabric, and can be widely applied in the fields of outdoor work clothes, sportswear and the like.
