The invention belongs to the field of vacuum heat insulation boards, particularly relates to a core board material of a vacuum heat insulation board for buildings and aims at the problems that existing core materials do not have excellent pressure resistance stability and heat insulation stability, and are higher in heat conductivity, high in cost and difficult to process, and thermal inertia andheat insulation fail to meet strict requirements. The core board material is prepared from the following raw materials in parts by weight: 23-26 parts of mineral wool, 18-22 parts of glass fiber, 22-26 parts of silica, 14-18 parts of calcium chloride hexahydrate, 8-12 parts of quicklime, 6-9 parts of acrylic acid, 7-11 parts of polyvinyl alcohol, 4-8 parts of potassium hydrogen sulfite, 13-16 parts of bentonite, 11-14 parts of quartz sand, 9-13 parts of magnesium oxide, 5-8 parts of zinc oxide and 30-35 parts of deionized water, wherein rock cotton fiber accounts for 20-25 parts of the mineralwool. A preparation method of the core board material comprises the following step: S1, adding acrylic acid and deionized water to a reaction kettle. The core board material has excellent pressure resistance stability and heat insulation stability, low heat conductivity, high hardness, excellent thermal inertia and heat insulation effect and low manufacturing cost, and is convenient to process.

The invention provides a low-energy-consumption container house and an operation method thereof and belongs to the field of buildings. The low-energy-consumption container house and the operation method are used for solving the problems that an existing container house is poor in thermal performance, poor in comfort degree under the hot condition in summer and the cold condition in winter, and high in energy consumption per unit area. The low-energy-consumption container house comprises accessories such as a universal container plate and frame, an additional supporting structure, a bottom plate, a wall and top plate composite enclosure structure, a door-window and hole enclosure structure, an enclosure structure additional pipeline and water tank, a circulation water radiator, a capillaryhumidifying and evaporative cooling device, foldable supporting feet and foldable stair railing platform awning. The low-energy-consumption container house has the main characteristics that the low-energy-consumption container house can be arranged overhead; in summer, through the composite enclosure structure, sun-shading and ventilation can be achieved, the thermal inertia can be improved by filling water, and radiating and evaporative cooling are achieved through bottom plate circulation water; and in winter, heat preservation capacity can be improved through an air interlayer formed by draining water, meanwhile, low-temperature hot water radiation heating is conducted through the bottom plate; and thus indoor comfort and low-energy-consumption operation all year round are achieved.

The invention discloses a treatment method and a treatment device for tobacco stems. The processing method of the tobacco stems mainly includes the steps of material preparation, solid heat medium mixing, expansion treatment, and separation. By mixing the tobacco stems with solid heat medium and high-temperature gas heat medium, they are irradiated with microwaves, and the gas, solid heat medium and microwave radiation are irradiated. High-quality expanded tobacco stems can be obtained by simultaneously heating the inside and outside of the tobacco stems according to the common practice; the processing device is provided with sequentially connected feeding equipment, a closed vibrating conveyor, a microwave stem expanding device, and a vibrating screening machine. Tobacco stems mixed with solid heat medium, high-temperature gas heat medium are fed into the stem expansion device, and microwaves are emitted, so that the gas, solid heat medium and microwave irradiation can heat the inside and outside of the tobacco stem simultaneously, thereby obtaining high-quality expansion. Tobacco stems.
