What is nano-silicon powder? Nano silicon 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. It is used for bricks, cement, Gypsum, lime, paint, asbestos, perlite, insulation board. 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.
Application method of nanometer silicon powder waterproof agent Spraying construction: clean the base surface (especially oil stain and moss) before use, mix the nano silicon waterproof agent with eight times of clean water evenly, and use a spray or brush to directly construct on the dry base surface at least twice continuously vertically and horizontally (the second time when the last time is not dry), for the rough surface of 1:2.5 mortar, it can penetrate about 1mm deep, and the effective life can reach 5 to 10 years, each time can construct about 40 to 50m2 per kilogram of this agent, and it cannot be soaked by rain and water within 24 hours after construction, The construction shall be stopped below four ℃. After drying at normal temperature, the waterproof effect will be excellent, and the effect will be better after one week (the curing time in winter is longer). The test shows that the waterproof test block, after curing, has been repeatedly calcined at 300 ℃ for 20 times and repeatedly frozen at - 18 ℃ 20 times; the waterproof effect has not changed significantly. The diluent is ready for use and used up on the same day.
Preparation of nano-silicon powder Plasma enhanced chemical vapor deposition (PECVD) method: The substances in the plasma state are composed of ionized conductive gases, which have extremely high energy and activity. The plasma-enhanced chemical vapor deposition method ionizes silane (SiH4) by glow discharge and then deposits nanometer silicon powder on the substrate. By adjusting the process parameters, the particle size of silicon powder can be controlled to vary from 10 to 200 nm. The advantage of the PECVD method is that the size of prepared silicon powder can reach below 50 nm. The particle size stability is good, the basic reaction temperature is low, the deposition rate is fast, and mass production has been achieved. Still, this method also has great disadvantages: first, the raw material SiH4 is a flammable and explosive gas, and there are great safety hazards in the transportation and production process; second, the large-scale production equipment investment is large, the cost is high, the production process is accompanied by strong radiation, the overflowing metal vapor dust and other harmful to the human body, and the generated harmful waste gas is difficult to be treated.
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.
