The invention provides a manufacturing technique of a luminous LED sandwich glass capable of luminous with controlled luminous effect; a film structure of the LED sandwich glass includes a glass plate, an adhesive layer, a LED layer and a conductive coated glass plate in order. The main manufacturing steps are as follows: cleaning and drying the conductive coated glass plate, scribing a pre-designed LED circuit thereon, adhering LED and a power source lead, drying it, paving the intermediate adhesive layer, closing sheets, undergoing vacuuming and pre-pressing high pressure and temperature treatments of a high-pressure autoclave; designing various LED layout circuits on the LED luminous sandwich glass, so as to control luminous quantity, luminous effect and various luminous acts of the whole glass.

The invention discloses a method for preparing high-resilience thermoplastic polyurethane foamed particles and a molded body thereof. Thermoplastic polyurethane particles are placed in an autoclave, injected high-pressure mixed fluid is one or two of CO2, N2, HFC and HCFC, one or two of chloroform, ethanol, methanol, acetone, anone, butanone, pyridine, N-methyl pyrrolidone, N,N-dimethylformamide and N,N-dimethyl acetamide serve as an organic cosolvent, and the high-pressure mixed fluid is enabled to be in a saturated state in the thermoplastic polyurethane particles and then is placed in hot air for foaming, thereby obtaining the thermoplastic polyurethane foamed particles, of which foamed pore structures are uniform and are closed-pore structures. The thermoplastic polyurethane foamed particle molded body, which is light in weight, high in resilience and controllable in shape size and has good mechanical properties, can be obtained through injecting the thermoplastic polyurethane foamed particles in a mold and adjusting mold pressing temperature and pressure so as to soften heated surfaces of the foamed particles.

The invention relates to a technology for making bricks from aggregate waste residues. The technology comprises the following steps: S1, obtaining the aggregate waste residues; S2, crushing the aggregate waste residues to form a powdery material; S3, taking the powdery material obtained in step S2, cement plant kiln dust and cement in proportion to obtain a mixture, wherein the mixture contains, by mass, 75-77% of the aggregate waste residues, 9-11% of the cement plant kiln dust and 10-13% of cement; S4, adding water accounting for 0.5-1% of the total mass of the mixture into the mixture, andperforming stirring; S5, feeding the stirred mixture obtained in step S4 into a press mold for molding, and pressing the molded mixture to form green bricks; and S6, carrying out autoclaved curing onthe green bricks by using an autoclave. The technology for making bricks from aggregate waste residues can effectively utilize the aggregate waste residues and reduce the discharge amount; and all theraw materials used for making the bricks come from the self cement plant and the aggregate factory, so the industrial chain of the cement enterprise can be easily extended to form circular economy enterprises.

The invention provides a TPU particle foaming process. The TPU particle foaming process comprises the following steps: selecting TPU particles; soaking: placing the TPU particles in an autoclave, sealing the autoclave, introducing supercritical CO2 into the autoclave, pressurizing the autoclave to enable the CO2 and the TPU particles to reach a saturated state, and emptying the supercritical CO2 at a constant speed for 3 to 5 minutes so as to obtain swelled and unfoamed TPU particles; foaming: taking the swelled and unfoamed TPU particles out of the autoclave, and placing the TPU particles in constant-temperature hot air equipment to obtain TPU foamed particles; and shaping the particles: placing the TPU foaming particles in a pressure maintaining container, introducing dry air into the pressure maintaining container till the pressure reaches 0.75 MPa, then introducing CO2 into the pressure maintaining container till the pressure in the pressure maintaining container reaches 1.5 MPa, maintaining the pressure for 15 to 18 h, and obtaining the final TPU foaming particles. The particles are full in appearance and high in glossiness.
