The invention relates to the field of filling, in particular to a lightweight filling material as well as a preparation method and a use method thereof. The light filling material is prepared from a composition A and a composition B according to the mass ratio of 1: 1, and the composition A is prepared from, by mass, 60-75 parts of water, 70-75 parts of Portland cement clinker, 15-22 parts of fly ash and 8-10 parts of sodium percarbonate; the composition B comprises the following components in parts by mass: 60-75 parts of water, 25-30 parts of lime, 47-50 parts of gypsum, 8-18 parts of stone powder and 10-12 parts of a foam stabilizer. After the light filling material is filled to a position needing to be filled, the light filling material can be cured and formed to obtain a filling body, the density of the filling body is 300-900 kg / m, and the compressive strength of the filling body is 0.23-25 MPa.

The embodiment of the invention discloses a replenishment duration information generation method and device, equipment, a medium and a program product. One specific embodiment of the method comprises the following steps: determining item circulation time period type information corresponding to a target item on a target date; determining a target replenishment time length information generation model corresponding to the target article according to the article circulation time period type information; and generating replenishment duration information corresponding to the target article according to the target replenishment duration information generation model and the article information corresponding to the target article. The implementation mode is related to an intelligent supply chain, and the accuracy of the determined replenishment duration is improved, so that the article loss can be reduced, and the transportation resources are saved.

The utility model relates to the technical field of packaging boxes, in particular to a profiling box sleeve for packaging L-shaped parts, which comprises a first box body and a second box body. Wherein the first box body comprises a first bottom plate and a first cover plate; the second box body comprises a second bottom plate and a second cover plate; the second bottom plate is fixedly connected with the first bottom plate, and a crease line is arranged between the second bottom plate and the first bottom plate. The profiling curve of the profiling box sleeve fits the appearance curve of the L-shaped part, so that the L-shaped part can be better buffered and protected; and meanwhile, the use amount of packaging paperboards can be reduced, the packaging cost of parts is saved, the transportation space can be saved, and the transportation cost is reduced.
