Abstract: In all freezers and refrigerators all have integral plastic inner frame and the refrigerator door mezzanine both are filled with injection-type Styrofoam to keep cold. The plastic inner frames and Styrofoam are both environmentally unfriendly and difficult to recycle and wasteful a lot of energy.

Abstract: In 2021, major industrial countries announced a 50% carbon reduction in 2030. Disposable paper cups with plastic inner membranes and disposable plastic cups are banned globally are required for recycling and reuse. Double-layer near-vacuum metal foil cups with cold and warm preservation functions, also for keeping cold and warm preservation are Low-carbon market needs.

Abstract: At present, all public spaces and offices around the world use light steel hangers and 2?×2? ceiling board or 4?×8? indoor compartment gypsum board for the beauty and fire protection. Thermally soundproof, but the board is not encapsulated with a metal film and then vacuumed. In the long term, the moisture of the water molecules contained in the micron-sized pores would have been transported through the asbestos fibers, therefore become the medium for conducting sound waves and heat. It is necessary to enclose the board with metal film and then vacuumed in order to improve fire and sound insulation.

Abstract: Currently wood frame dwellings in North American and the steel structures of the building constructions worldwide, in which the row of toilet water pipes are routed within the fire wall, when the toilet flushes, the water enters into the drainage pipeline. The original static air generates a huge sound wave, and the laminated mezzanine formed by the fireproof gypsum board outside the wood structure wall will increase the noise due to resonance, and the quality of life in the living space will be greatly disturbed. Therefore, some kind of sound insulation is required. Sound proof composite materials prevent noise, while the space walls and interior walls of high and low-latitude structures are heat-retaining and energy-saving. In addition, air-conditioning and hot water pipelines in buildings need to be insulated and cold-resistant to provide good insulation, using flame-retardant materials. In particular the plumbers need to do the installation of insulation construction fast and alone.

Abstract: There are multiple adaptors or lamp holder in market to connect the power and pin based CFL. This innovation consists of a lamp-holder along with an easier replaceable Combination with integrally ballast circuit adaptor. This design is applicable to the use of GX10q based CFL. The purpose and special feature of this GX10q Combination being applied to pin-based CFL fixture, the internal ballast is easier replacement.
