The invention relates to the technical field of macromolecular polyethylene foaming materials, and discloses a gel network supported chemical foaming agent as well as a preparation method and application thereof. The gel network supported chemical foaming agent contains a gel network carrier and azodicarbonamide supported on the gel network carrier, and based on the total weight of the gel network supported chemical foaming agent, the content of the azodicarbonamide is 10-40 wt%, and the content of the gel network carrier is 60-90 wt%. The gel network supported chemical foaming agent has the advantages of lower initial foaming temperature, controllable decomposition process, smaller cell size and better application value.

The utility model discloses a decomposer for food detection, which relates to the technical field of food decomposers and comprises a sealing tank, a sealing plate and a locking box, the sealing plate is movably mounted on one side of the top of the sealing tank, the locking box is mounted on one side of the sealing tank, the locking box is locked and meshed with one side of the sealing plate, and the sealing plate is movably mounted on one side of the sealing tank. A stirring assembly is fixedly connected to the bottom of the inner wall of the sealing tank, the interior of the sealing tank is uniformly stirred through transmission, an observation assembly is arranged on the top of a sealing plate, and the interior of the sealing tank is conveniently observed through scraping cleaning. According to the utility model, the observation assembly is arranged to observe the interior of the sealing tank, and then the stirring assembly is used to uniformly stir the interior of the sealing tank, so that the problem that the decomposition device needs to open a tedious secret method structure when stirring decomposed food, and the food cannot be conveniently decomposed is solved; the effects that the food decomposition condition can be observed, and meanwhile uniform stirring can be conducted are achieved.

The application discloses an ultrahigh molecular weight polyethylene-acrylonitrile butadiene rubber composite elastic material, which comprises 70wt%-95wt% of ultrahigh molecular weight polyethylene and 5wt%-30wt% of acrylonitrile butadiene rubber powder, has an island-sea structure, wherein the acrylonitrile butadiene rubber powder is a dispersed phase, the ultrahigh molecular weight polyethylene is a continuous phase, and the dispersed phase and the continuous phase are connected by C-C chemical bonds; and the particle size of the acrylonitrile butadiene rubber powder is less than or equal to 0.7mm. By limiting the content of the ultrahigh molecular weight polyethylene and the acrylonitrile butadiene rubber powder, combining the connection between the two phases by C-C chemical bonds and limiting the particle size of the acrylonitrile butadiene rubber powder, the rubber particles in the composite elastic material are first deformed when the composite elastic material is subjected to external force, so that the composite elastic material has good resilience and lower permanent deformation at a smaller strain.

The invention belongs to the technical field of secondary aluminum refining, and particularly relates to a secondary aluminum refining method and device. The copper chloride is creatively used as the refining agent of the secondary aluminum, and the dispersion method, the adding speed and the adding amount of the copper oxide are limited, so that the copper chloride powder can be ensured to quickly and uniformly enter the secondary aluminum melt, the reaction is ensured to be quickly and efficiently carried out, and the optimal magnesium removal and impurity removal effects are further achieved. The molar ratio of Mg in the aluminum alloy melt to Cl in the added copper chloride is limited and controlled to be 1: (2-3), it is ensured that Mg, part of gas and non-metal impurities in the regenerated aluminum melt can be fully removed, meanwhile, it is ensured that the copper chloride magnesium removal refining agent reaches the high utilization rate, resource waste is avoided, and the production cost is reduced. And meanwhile, the introduction amount of the copper element in the secondary aluminum can be within a controllable range, so that the copper element is prevented from exceeding the standard.
