There are currently two types of polymer cement waterproof mortar in China:

1. It is a finished mortar prepared by the manufacturer, which is divided into single component (dry powder) and two components (powder + lotion) two types.

Both of these two methods are very effective, but the disadvantage is that the cost of use is very high, especially the latter's two-group classification, which is only a few millimeters thick, and the square material cost is as high as ten yuan; therefore, the scope of use Very restricted.

2. It is in the form of an admixture. The emulsion-type polymer cement mortar modifier has been used in China. The method of use is to use it at the construction site according to the mix ratio (usually the weight ratio, emulsion: cement: sand =1:2:4) mixed with cement sand before use. After modification, a high-performance polymer cement mortar is obtained. The use effect is very good, but the relative cost is lower than the two-component classification, but the amount of emulsion reaches that of cement. Calculating half of the construction thickness of 5 mm, the square material cost will also reach more than 10 yuan.

3. Key point! ?It is also in the form of an admixture. Features: low cost of use (compared to emulsion polymer cement mortar modifier, it can save 10 times the dosage and 8 times the cost),

low cost! It can be realized that all plastering mortars on the wall are made of polymer cement mortar (thickness is about 20 mm). This can not only improve the quality of the project, but also reduce material costs, construction links, construction period, and labor costs.

Powder type polymer cement mortar modifier is a patented product of our company Shenzhen Jinyuan Construction Technology Development Co., Ltd.! It is Shenzhen's 2008 construction science and technology project establishment and construction science and technology achievements promotion and transformation guide project. National invention patent product! (Patent No.: ZL200710073239.1?)

Brief description: Zhulong 205? type polymer waterproof mortar additive (modifier) ??is compounded of imported polymer powder, anti-crack fiber, polyacrylate and other polymer materials and other fillers . Mixed with cement mortar, mixed and used. After modification, it can be made into a high-performance polymer cement waterproof mortar, which can be used for waterproofing and anti-cracking projects in buildings and ceramic tile bonding; it is crack-resistant, impermeable, waterproof, moisture-proof, anti-freeze, It has multiple functions such as anti-scouring and corrosion resistance, which can accelerate the hydration and dispersion of cement particles, reduce water consumption, plug the pores left after the mortar hardens and water evaporates, so that the mortar does not produce dry shrinkage cracks and reduces water absorption. It can achieve the purpose of waterproofing, impermeability, crack resistance, increasing pressure resistance and bonding strength; it is a new generation of environmentally friendly building waterproofing material.

Features: (save construction period, reduce cost, improve quality)

1. Good bonding and flexibility.

2. Easy to use and can be applied directly to wet base surfaces.

3. Corrosion resistance, high temperature resistance, low temperature resistance and aging resistance.

4. It does not deteriorate, resists earthquake cracking, is non-toxic, harmless, tasteless and does not pollute the environment.

5. If there is no human or structural damage, it can last as long as the building.

6. Various finishing layers (such as paint, ceramic tiles, etc.) can be made directly on the waterproof layer.

It solves the problem that polymer cement waterproof mortar can only be made a few millimeters thin due to high cost factors. With Zhulong 205, the square meter cost of 20 mm thickness is only 6 yuan more than ordinary cement mortar. about! The polymer cement waterproof mortar can be used to completely complete wall masonry, leveling, plastering, waterproofing, crack resistance and ceramic tile bonding all at once! The mortar is mixed and used with the powder polymer cement waterproof mortar modifier. While improving the quality of the project, it also reduces material costs, construction links, construction period, and labor costs! It is of great significance in improving economic, social and ecological benefits; it is the preferred waterproof material for interior and exterior walls.
