White cement is a white hydraulic cementing material prepared by burning raw materials with proper components until the raw materials are partially melted, adding a proper amount of gypsum into clinker with low iron content, and grinding.
The main chemical constituents of ordinary cement are calcium oxide, silicon oxide, aluminum oxide and iron oxide. The calcium oxide is mainly derived from calcareous raw materials, such as limestone, chalk, marl and the like; the alumina and the silica are derived from aluminum silicate-containing substances, such as clay, blast furnace slag, fly ash and the like; the ferric oxide utilizes pyrite slag in the production of sulfuric acid. The content of calcium oxide in the calcareous raw material for producing the portland cement is about 52 percent generally; the content of silicon oxide in the clay raw material reaches about 57 percent, and the content of aluminum oxide is less than 20 percent. In order to lower the calcination temperature and to form a part of the melt during calcination, a small amount of iron oxide raw material is often added.
The expanding agent is a chemical additive added in cement, when the cement is set and hardened, it expands with the volume, and plays the role of compensating the shrinkage and stretching the reinforcing bar to generate prestress and fully filling the cement gap.
The WLA-A waterproof powder is prepared by adding an organic silicon emulsion into water and stirring to prepare a solution A; injecting into a stirrer for stirring, sequentially adding cement and filler for stirring, and discharging to obtain material B; putting the material B into a wood die, placing the wood die on a layer frame, naturally condensing at normal temperature, demoulding and naturally drying to prepare a material C; the waterproof powder has certain crack resistance, impermeability and weather resistance, and can play waterproof, impermeable and protective roles.
Further, the adhesive is 107 glue. The 107 adhesive is polyvinyl formal adhesive and is formed by solution or emulsion with water as a medium. The 107 glue has the characteristics of non-ignition, low price, convenient use and the like, is widely used in building engineering, and can be used as building adhesive and base materials of various interior and exterior wall coatings and ground coatings.
Further, the first screw is screwed into the pull rod hole for at least 30mm, so that the first screw is fully contacted with the PVC sleeve, and a stable connection is formed between the first screw and the PVC sleeve.
