Which models of HPMC and dispersible latex powders are commonly used for mortar and putty?

Gray calcium is more than 325 mesh (below), whiteness is more than 90, the content is increased, the water resistance is good, but the grinding is 20-40% poor

Heavy calcium is more than 200 mesh (below), and the whiteness is more than 80.

Filler, talcum powder and large white powder with the same requirements can be used instead of 80-60% cellulose HPMC (hydroxypropyl methylcellulose) 40,000-100,000 viscosity to increase workability and water retention by 4-6%.

Rubber powder Medium viscosity Increase bond strength and toughness, repeated workability 4-10% rubber powder is recommended to use well-known domestic manufacturers, such as Wanwei 8010 or 8020, cellulose can be used Zhiwei Chemical and Shandong Yiteng, both of which are well-known domestic manufacturers.

HPMC commonly used is 100,000 viscosity and 200,000 viscosity, manufacturers include Shantou Longhu Technology, Shandong Huawei. Dispersible latex powders are available from WACKER (W5044) and Dalian Chemical (DA1410).

The commonly used 200,000 viscosity, redispersible polymer powder is the DM-200 model. The quality of Shandong Ruitai in China is stable, about 32 per kilogram. It can also be replaced with rubber powder.

Three-dimensional and Fang Dakang's are OK, more than 20 yuan a kilogram.

I've been doing this for many years, and if you want to use a kind of Shijiazhuang Ruixue or Shijiazhuang other, the viscosity is 100,000, and the current ** is about 26 to 27 a kilogram. I still recommend using Shanxi three-dimensional !! The price of Type 04 and Type 05 is basically 17 to 19 yuan a kilogram!!

These two manufacturers are the most cost-effective of these!!

Redispersed latex powder products are water-soluble redispersible powders, copolymers of ethylene vinyl acetate, tertiary ethylene carbonate copolymers, acrylic acid copolymers, etc., with polyvinyl alcohol as a protective colloid.

Because it has a very outstanding bond strength, improve the flexibility of the mortar and have a long opening time, give the mortar excellent alkali resistance, improve the adhesion of the mortar Adhesion, flexural strength, waterproofness, plasticity, wear resistance and construction, in the flexible anti-cracking mortar has a strong flexibility, therefore, their application range is extremely wide.

Better close the void of the substrate, reduce the water absorption of the wall, improve the surface strength of the substrate, and ensure the cohesion of the mortar.
