Abstract: The present disclosure relates to an automatic control type hot smoke testing system which includes a fire source system, a smoke generation system and a control system. The fire source system is used for generating fire source and includes a first tank and several liquid fuel atomizing jet burners, wherein the first tank includes an air tank which is used for providing air and a fuel control tank which is used for controlling valves, distributing fuel and inspecting flame of the burners. The smoke generation system is used for generating smoke and includes a second tank, a smoke outlet pipe, smoke cake clamps and smoke cake turntables. Smoke cakes are initially placed in the smoke cake clamps, then moved to an ignition position one by one by for ignition, and finally rotated to through hole positions of a smoke generation box to fall into the smoke generation box by the servo motor. The control system is used for controlling the fire source system and the smoking generation system. The present disclosure overcomes the defects of the traditional manual hot smoke test, and realizes the accurate control of the smoke generation speed, the fire source power and the burning time, which has the characteristics of accuracy, light weight, automation and convenient disassembly and transportation.

Abstract: Disclosed are a grouting pipe and a construction method of a desert water storage area. An isolation layer can be constructed in any desert area to form the water storage area. A plurality of anchoring claws are arranged between an inner pipe and an outer pipe of a pipe body. The anchoring claw has a grouting flow channel for grouting into surrounding sand grains. When the grouting pipe is being laid, the anchoring claw is folded. During grouting, an elastic bag structure supports the anchoring claw. The pipe body can be firmly anchored in the sand grains. Slurry sprayed out of the anchoring claw moves from the pipe body by a certain distance, with a wider flowing range in the sand grains, and can meet and condense with slurries of other drilled holes, which facilitates better formation of the isolation layer, so that the desert water storage area is formed.

Abstract: The present disclosure relates to a flame retardant composed of multi-component phase change material particles. These particles consist of paraffin wax, nano-flame retardant, and conventional flame retardant. The phase change material is modified with nano-flame retardant and physically coated with conventional flame retardant. The multi-component phase change material flame retardant is formed by creating a two-layer nucleus-shell structure. The nucleus core is made up of the conventional flame retardant, while the shell layer is composed of the nano-flame retardant doped phase change material. The multi-component flame retardant material combines the performance advantages of phase change material, nano flame retardant, and conventional flame retardant. The combination of nano flame retardant and phase change material weakens the disadvantages of phase change material and allows for the full utilization of the energy storage capabilities of the phase change material.
