This utility model discloses a multifunctional artificial field ridge, relating to the field of agricultural facility technology. It includes several main units that interlock along their length. Each main unit has a support leg embedded in the soil at its base, and an arched structure with a downward-facing arc-shaped opening between two legs. Side plates are located on both sides along the length or short side of each main unit. A mulch film fixing clip is attached to the side plate of the main unit, having a slot for fixing the edge of the mulch film. A pre-drilled hole is located on the side plate of the main unit. A pipe fixing clip is also located on the side plate of the main unit, with a buckle inserted into the pre-drilled hole on the side facing the main unit. By integrating multiple functional components such as the mulch film fixing clip, pipe fixing clip, and support fixing block onto the side plate of the main unit, the efficiency of mulch film laying, irrigation pipe installation, and protective facility construction is improved, while significantly reducing on-site construction complexity and the required labor.

The present invention relates to a two-component spraying unsaturated polyester resin putty and a preparation method thereof, belonging to the technical field of unsaturated polyester resin putty, and the preparation method comprises the following steps: S1, using phthalic anhydride, hexylene glycol, triethylene glycol, linoleic acid, propylene glycol, neopentyl glycol, a catalyst and maleic anhydride to make a self-made resin; S2, taking the self-made resin and adding zinc stearate, montmorillonite, precipitated white carbon black, titanium dioxide, accelerator, inhibitor, poly [1-(methoxycarbonylmethyl)ethylene] and styrene to prepare the main ash; S3, preparing a putty finished product. The present invention adds linoleic acid and triethylene glycol to accelerate the surface dryness of the putty; in addition, the present invention also uses zinc stearate, montmorillonite, precipitated white carbon black and titanium dioxide in combination, and synergistically improves the polishability of the unsaturated polyester resin putty. The addition of poly [1-(methoxycarbonylmethyl)ethylene] increases the anti-settling effect of the filler and prolongs the storage period of the finished product.

This invention relates to a degumming composition, its preparation method, and the degumming method thereof. The degumming composition comprises the following components in weight percentages: 84%–93.5% degumming solvent, 3%–5% solvent oil, 0.5%–3% solid wax, 1%–3% organobentonite, and 2%–5% polar activator; wherein the degumming solvent includes one or more of dichloromethane, N-methylpyrrolidone, and ethylene glycol monobutyl ether. This invention combines the degumming solvent, solid wax, solvent oil, organobentonite, and polar activator in a specific ratio, achieving synergistic effects among the components to obtain a degumming composition with slow evaporation and short degumming time.
