The raft foundation chilled water storage device comprises a plurality of building raft foundation trough bodies which are arranged adjacently. The side wall of each building raft foundation trough body is provided with water through holes, and chilled water is guided to flow among the raft foundation trough bodies through the water through holes. The raft foundation chilled water storage device has the advantages that a labyrinth cold accumulation mode is put forward, an underground raft foundation area is fully utilized for chilled water storage, the initial investment for a system is reduced, and the use space is saved; the operation possibility of a non-occupation type cold accumulation mode is reserved, when not ideal, the actual operation effect of the labyrinth chilled water storage mode can be switched to the non-occupation type cold accumulation mode for operation, and the performance reliability is improved; a heat preservation form of polyurethane on-site foaming is adopted in heat preservation of the raft foundation trough bodies, and the advantages of good heat preservation and insulation effects, good chemical stability and convenient construction are achieved; a polyurea waterproof system is adopted in the waterproof technology and has the advantages that solidification is quick, the construction efficiency is high, and the ageing-resistant performance, salt corrosion resistance, thermal stability, binding power and the like and good.

A kind of ecological planting ceramsite and preparation method thereof
ActiveCN112374813BHigh strengthImprove water absorptionHops/wine cultivationGrowth substratesEnvironmental resource managementPolymer adhesive
The invention discloses an ecological planting ceramsite and a preparation method thereof. The raw material ecological planting ceramsite includes: clay, geopolymer gelling material, liquid activator, water, nutrient matrix, organic binder and alkali-resistant grass seeds ; Fully mix the pretreated clay, geopolymer cementitious material, nutrient matrix and grass seeds to obtain a mixture; spray the mixed aqueous solution of liquid activator and organic binder into the obtained mixture, stir and mix well and then granulate and maintain the ecological planting ceramsite. The ecological planting ceramsite does not require a sintering process. Compared with the sintered ceramsite, the unfired ceramsite has the characteristics of higher water absorption, salt corrosion resistance, and good durability. At the same time, it has high strength, light weight, and good durability. Under the conditions of suitable moisture and temperature, the grass seeds in the ceramsite can grow. The burning-free ecological planting ceramsite is energy-saving and environment-friendly, and enables solid waste such as waste clay to be effectively utilized.

Phase-change expanded fireproof multi-component alkyd resin transparent primer and preparation method thereof
ActiveCN108531054AImprove the decorative effectImprove water resistanceFireproof paintsPolyester coatingsCarbon layerPhosphate
The invention discloses phase-change expanded fireproof multi-component alkyd resin transparent primer and a preparation method thereof. The primer comprises a component A and a component B, and the weight ratio of the component A to the component B is 1:(0.8-1.2). By weight, 40-70 parts of alkyd resin, 20-30 parts of starch phosphate, 2-4 parts of polyoxyethylene ether oleate dust-proof agents, 0.5-1.0 part of organic silicon defoaming agents, 0.05-0.1 part of zinc isoocatanoate driers, 3-6 parts of acetone and 20-50 parts of phase-change fireproof slurry are sheared, stirred and mixed to obtain the component A. The component B comprises 30-50 parts of curing agents and 40-60 parts of diluents. The multi-component alkyd resin transparent primer is colorless, transparent and suitable for natural color coating of wooden furniture, most heat can be absorbed by phase change at the initial stage of a fire to inhibit flames, thermal decomposition is performed at the later stage of the fireto form an expanded foam carbon layer for effectively isolating the heat and air, internal materials are effectively protected from fire harm, the flames are effectively isolated, and fire spread is stopped.
