The invention relates to a lignin phenolic resin environment-friendly plate and belongs to the technical field of building materials. The environment-friendly plate comprises an upper coating, an upper plate, a middle coating, a lower plate and a lower coating sequentially arranged from top to bottom. The lignin phenolic resin environment-friendly plate is high in surface layer density, high in strength, less prone to deformation, simple in production process, high in production efficiency, definite in process parameter, high in operability and capable of directly serving as a material for furniture and indoor decoration, has the advantages of high anti-seismic performance, flame retardance, low smoke, nontoxicity, water resistance, moisture resistance, corrosion resistance, resistance to high temperature, insulativity, light weight, quickness in mounting, antiaging resistance and wear resistance and is pollution-free, safe, environment-friendly and long in service life, and artificial forest soft wood does not need to be treated in a sealed container.

The invention discloses a damp-proof sound-absorbing building envelope with an air layer. The damp-proof sound-absorbing building envelope is characterized by comprising an exterior trimming panel, a heat-insulating waterproof layer, an outer layer flame-retardant sound-absorbing heat-insulating material layer, a vapor blocking layer, an inner layer flame-retardant sound-absorbing heat-insulating material layer and an interior trimming panel which are all arranged in sequence from the outside to the inside of a room. The air layer which is sealed relatively is formed between the exterior trimming panel and the heat-insulating waterproof layer. By the arrangement of the air layer and the matched design of the heat-insulating waterproof layer, the inner layer flame-retardant sound-absorbing heat-insulating material layer, the outer layer flame-retardant sound-absorbing heat-insulating material layer and the vapor blocking layer, humidity accumulation in a heat-insulating material can be effectively avoided, and the problem that the durability, structural strength and heat insulation of a heat insulation system are affected due to poor moisture penetrability in the heat insulation system is solved. The damp-proof sound-absorbing building envelope is clear in hierarchical structure and is good in heat insulation, energy saving performance, moisture penetrability, damp prevention and sound absorption, and the shortcoming that the building porous material external building envelope is internally easily affected with damp, condensation and mold and is non-breathable and poor in sound absorption can be fundamentally overcome.

The invention relates to a display cabinet, specifically to a refrigerating display cabinet. The refrigerating display cabinet comprises a movable push rack, a display cabinet and a display cabinet cover plate, wherein the display cabinet is rotationally connected to the upper end of the movable push rack, and the display cabinet cover plate is glidingly connected to the display cabinet; the display cabinet comprises an outer frame, an inner frame and a frame end cover, the inner frame is fixedly connected to the inner side of the outer frame, divides the outer frame into a plurality of refrigerating chambers, and comprises a center sleeve, a plurality of partition plates, and pressing piece components, and the pressing piece components are glidingly connected to both ends of each partition plate; the refrigerating display cabinet disclosed by the invention has the beneficial effects of being capable of rotating by the movement of the movable push rack or rotating in the reverse direction separately, having a good display effect and being beneficial to temperature equalization among different chambers; various chambers are communicated, thereby being conducive to the temperature equilibrium among various chambers, and one chamber can be separately sealed with adjacent chambers while opened, thereby being favorable for thermal insulation and energy saving.

The invention relates to a dust haze preventing energy-saving window, and belongs to the technical field of building. The dust haze preventing energy-saving window comprises a fixed sash and an opening sash, wherein the opening sash is arranged on any side edge of the upper side edge, the lower side edge, the left side edge and the right side edge of the fixed sash and is in a narrow-strip shape. The opening sash is a ventilating sash and comprises an inner window body and an outer window body, the outer window body is a glass window, the window face of the inner window body is formed by sandwiching a filtering cotton layer in a double-layer steel wire gauze, the inner window body is opened inwards, and the outer window body is opened outwards. When the outer window body of the opening sash is opened, and the inner window body of the opening sash is closed, the heat preservation performance of the energy-saving window is equivalent to that of a double-layer glass window, and while the requirement for ventilation of a room is met, it can be ensured that indoor temperature does not fluctuate substantially, which is beneficial to health of people and plants in the room and heat preservation and energy conservation of a building. The dust haze harm is effectively reduced, and dust and mosquitoes are prevented from entering the room. The ventilating performance can fully meet the requirement for ventilation of the room, the ventilation property is 300 mm / s, and therefore the ventilating effect is excellent.
