Introduction:
Waterproofing is not a new topic, whether it is tunnels, bridges, dams, roads, buildings or our daily houses, waterproofing can not be ignored. At the same time, the electrical products used in our daily life also have the problem of waterproof and moistureproof, which must be faced directly.
Performance and application of nano-silicon waterproof agent
The patented product nano-silicon waterproof agent developed by Henan Sunshine Waterproof Technology Co., Ltd. is a new patented product with strong penetration and excellent waterproof effect developed and produced by high-tech nanotechnology. It is a kind of permeable crystallization, efficient and rigid building waterproof product. Nano-silicon waterproof agent is a water-based white emulsion, which is non-toxic and tasteless, with PH value 12, density 1. 18 ~ 1.2 and solid content ≥ 20%. Expensive waterproofing agent is sprayed on the surface of dry porous inorganic building materials such as brick, cement, stone, gypsum, lime, fangci paint, asbestos products, perlite, insulation board, etc. Very active nano-silicon particles penetrate into building materials, cross-linking to form a solid network crystal structure, blocking pores and forming a colorless permanent waterproof layer; At the same time, silane-based components are consolidated on the surface of building materials to produce strong hydrophobic molecules, which have excellent waterproof and impermeability. It can effectively prevent buildings from weathering and frost cracking, and has the functions of cleaning, anti-fouling, anti-mildew and anti-moss. Nano-silicon waterproofing agent is directly mixed into cement mortar or concrete, which is used for self-waterproofing projects of rigid structures such as pools, dams, culverts, toilets, bathrooms and basements. The unique waterproof effect of nano-silicon waterproof agent can be seen. Nano-silicon waterproof agent has reliable quality, good durability, acid and alkali resistance, excellent weather resistance, no corrosion to steel bars, safe use, convenient construction and low cost, and is one of the ideal waterproof materials in building engineering. The nano-silicon waterproof agent invented by Henan Sunshine Waterproofing Technology Co., Ltd. has impermeability of mortar ≥S 14 and concrete ≥S 18. The technical indicators meet the standards of JC 474- 1999[ Waterproofing agent for mortar concrete] and JC/T902-2002[ Permeable crystallization waterproofing agent].
Precautions:
(1) Wall treatment before waterproofing: The surface of the base coated with waterproof layer shall be free from irregularities, looseness, hollowing, sanding, cracking and other defects.
(2) Waterproof height: shower area is generally required, the height is greater than 180cm, and non-shower area is greater than 30cm.
(3) Tell the foreman and bricklayer in advance that the closed water test must be done, especially in the kitchen. Some kitchens have been plastered with wall tiles when doing closed water tests. The reason is that the bricklayer doesn't think it is necessary to turn off the water in the kitchen (it seems that many chefs still think that the kitchen doesn't need waterproofing, but some kitchens downstairs often leak water, so it is necessary to do it).
(4) Be sure to talk to the foreman and bricklayer in advance, and inform our owner in advance before the water closing test. The reason is that we can contact our neighbors downstairs. For example, when my family was waterproof for the first time, the master didn't tell me. As a result, I went downstairs to find my neighbor, who was not at home. Only after asking other neighbors did I know that their family had gone on holiday, and it might take a month or two to come back, so I had to pause first.
(5) It is suggested that when the closed water test is started, go to the neighbor's house downstairs for a look after 2 hours. The reason is that there is a problem with turning off the water. If there is leakage, it will not bring great losses to neighbors. If there is no problem, watch it again in 24 hours.
