What is nano-silicon powder? Nano silicon refers to silicon particles of nanometer size. Nano silicon powder is characterized by high purity, small particle size, uniform distribution, large surface area, high surface activity, and low loose density. The product is non-toxic and tasteless. Nano silicon powder is a new generation of photoelectric semiconductor materials with a wide gap energy semiconductor and is also a high-power light source material. White lotion, non-toxic, nonirritating, nonburning, PH value 12, density 1.15~1.2. It is used for bricks, cement, Gypsum, lime, paint, asbestos, perlite, insulation board, and other substrates that have an excellent waterproof and impermeable effect. It prevents weathering, frost cracking, exterior wall cleaning, antifouling, mildew-proof, and moss-proof. It has reliable quality, good durability, acid and alkali resistance, good weather resistance, no corrosion to reinforcement, safe use, and convenient construction. Mortar impermeability ≥ S14, concrete impermeability ≥ S18. Technical performance conforms to JC474-1999 [Mortar, concrete waterproof agent] standard and JC/T902-2002 standard.
Application of nano-silicon powder Waterproof mortar construction: clean the sediment, sundries, oil stains, etc. of the base course, control the ratio of cement to sand at 1:2.5~3 (425 # Portland cement, medium sand silt content is less than 3%), nano-silicon waterproof agent plus water 8-15 times (volume ratio) can be directly used to prepare waterproof mortar, the water-cement ratio is ≤ 0.5, and the actual amount of net waterproof agent accounts for 3~5% of the cement. The waterproof layer is constructed in two layers (each layer is 10mm thick), the bottom layer is plastered with 1 mm of plain mortar, and the waterproof mortar layer is plastered. The initial setting is compacted, and the wood trowel is used to poke into a pitted surface; after the second layer of waterproof mortar is plastered, it shall be polished and compacted. The cement curing agent produced by our company shall be sprayed according to normal curing.
Preparation of nano-silicon powder The fluidized bed method is to disperse solid particles into the fluid to have certain fluid characteristics. This state is called the solid fluidization state. SiH4 is introduced into the special fluidization equipment at a certain gas flow rate. It can react in the fluidized bed to form nano-silicon powder in the presence of specific catalyst particles. The particle size can be controlled by controlling the residence time of silicon particles in the reactor. The fluidized bed reactor has high output, The product particles are small, and the catalyst efficiency is high. Still, there are also disadvantages, such as a low primary conversion rate and serious back mixing. The catalyst particles, instruments, and equipment are severely worn during production, which greatly requires the catalyst's strength. When the gas flow rate is large, the catalyst particles can be carried out of the fluidized bed reactor.
Price of nano-silicon powder Nano-silicon powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of nano-silicon powder. A large amount of large amount will be lower. The price of nano-silicon powder can be found on our company's official website.
