HS-15JS polymer cement waterproof coating
Recently, Xiaobian has received a lot of customer consultation to understand HS-15JS polymer cement waterproof coating , now take everyone to science.
The origin of the name
J refers to polymer, S cement; that is, JS is a polymer cement waterproof coating, also known as JS composite waterproof coating ("JS" is the "polymer cement" pinyin prefix), is a polyacrylate emulsion for A two-component, water-based building made of a main polymer emulsion and an organic liquid material composed of various additives, and an inorganic filler composed of cement, quartz sand and the like, and various additives, which are compounded and compounded. Waterproof coating. In short, it is a material that is both rigid and soft.
JS waterproof coating type
JS waterproofing is divided into I, II, and III types according to the composition ratio of the film-forming materials. Based on this, based on the market and actual use, polymer cement mortars based on cement-based film-forming materials are further developed. These are collectively referred to as JS waterproof coatings. .
JS waterproof coating waterproof principle
It is an important application performance that utilizes high molecular polymer to modify cement, which can effectively improve flexibility and enhance the compactness of the paint film. The main waterproof mechanism is divided into:
1. Blocking the transmission of water molecules by forming a dense and complete coating film;
Second, through the hydrophobic effect of the coating itself to prevent the penetration of water molecules.
JS waterproof coating construction requirements
1. Base surface requirements: The base surface must be flat, firm, clean, free of water, no leakage, unevenness and cracks must be leveled first. Leakage must be treated first, and the yin and yang angles should be rounded.
2, accurate ingredients: strictly according to the packaging requirements described in the package, the mixture should be slowly added to the corresponding liquid material while stirring, and fully stirred to a uniform, fine mixture without agglomerates. And use mechanical stirring as much as possible, manual mixing must be sufficient, otherwise it will easily produce construction defects such as powder dough and bubbles.
3, coating essentials:
1 Coating with a roller or brush, layer by layer according to the order of the selected method.
2 If the paint has precipitation or slight delamination, stir it at any time.
3 coating should be as uniform as possible.
4 The time interval between the layers is preceded by a dry film coating that is not sticky.
