This utility model relates to a concealed, electrically operated, airtight window specifically designed for low-temperature grain storage, belonging to the technical field of grain storage equipment. It includes: a window frame, fixedly installed on the wall of a grain warehouse; a window sash, movably connected to the window frame via hinges, allowing the sash to rotate relative to the frame to open and close the window; a sealing assembly, disposed around the sash and on the window frame, forming a seal between the sash and frame when the sash is closed; an electrically driven assembly, fixedly installed on the window frame, having a drive unit that is connected to the sash; and a locking assembly, including a latch and a latch, the latch being on the sash and the latch on the frame, locking the sash when it is closed. This invention addresses the technical problem that existing electrically operated lifting windows cannot meet the temperature stability and high sealing requirements of grain silos used for low-temperature grain storage, necessitating a more reliable sealing solution and structure.

The invention relates to the technical field of aluminum veneers, in particular to a slotted aluminum veneer and a curtain wall thereof.The surface of the slotted aluminum veneer is sequentially sprayed with primer and finish paint, and the primer is composed of PVDF fluorocarbon resin, expanded microspheres, modified hollow glass microspheres, hexamethylene diisocyanate, an ammonium polyacrylate dispersing agent and deionized water; the finishing paint is prepared from PVDF fluorocarbon resin, thermosetting acrylic resin, a dispersing agent BYK-110, an acrylic leveling agent, butyl acetate and nano silicon dioxide. According to the slotted aluminum veneer prepared by the invention, the sound insulation performance and the wear resistance of the slotted aluminum veneer are improved by adding the expanded micro-beads and the modified hollow glass micro-beads into the primer, and the corrosion resistance of the slotted aluminum veneer is improved by the PVDF fluorocarbon resin, the thermosetting acrylic resin and the nano silicon dioxide in the finish paint.

This utility model relates to the field of polyethylene pipe technology, specifically disclosing a fireproof and heat-insulating polyethylene pipe, including an inner pipe layer. The outer wall of the inner pipe layer is co-extruded and composited from the inside to the outside, forming an inner flame-retardant layer, a heat-insulating layer, a reflective layer, and an outer fireproof protective layer. Both the inner flame-retardant layer and the outer fireproof protective layer are flame-retardant composite material layers, and the reflective layer is a high-reflectivity material layer. Through a multi-layer composite structure, it integrates pressure-bearing transportation, bidirectional flame retardancy, high-efficiency heat insulation, and radiation reflection functions into one, solving the various drawbacks of traditional pipes that require subsequent wrapping construction. It achieves inherent fire resistance and self-insulation of the pipe product, significantly improving the long-term safety, reliability, and energy-saving benefits of building pipeline systems. At the same time, it simplifies the installation process, reduces overall costs, and is safer and more environmentally friendly due to the selection of environmentally friendly materials and halogen-free flame-retardant properties.

The application discloses a kind of quick breaking electrical fire protection device, it is related to electrical fire protection device field, including fireproof shell and installation backplate, the bottom of fireproof shell is provided with dehumidification mechanism.This kind of quick breaking electrical fire protection device, by dehumidification mechanism can carry out dehumidification processing to equipment inside, blow heat dissipation fan can blow, can directly blow the air in the inner chamber of fireproof shell downwards, then cooperate with moisture fan, so that the humid air in equipment inside can be quickly sucked and removed, subsequently when humid air is sucked into the inner chamber of shell, will be sucked and removed with the dust blown off, effectively avoid that dust can be accumulated in the inside of fireproof shell, will not cause influence to electrical element, and by filter screen still can directly filter small dust, impurity etc., to effectively guarantee the dry degree of equipment inside, can also avoid to accumulate a large amount of dust, improve equipment service life.
