Hpmc as a water-retaining agent and retarder for cement mortar, it makes the mortar pumpable. In plastering slurry, gypsum, putty powder or other building materials, it is used as a binder to improve spreadability and prolong operation time.

VAE Re-dispersible Polymer Powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymers, vinyl acetate/ethylene tertiary carbonate copolymers, acrylic acid copolymers, etc. The powder sticky made after spray drying Mixture, using polyvinyl alcohol as protective colloid. This kind of powder can be quickly dispersed into an emulsion after contact with water. Because VAE Re-dispersible Polymer Powder has high bonding ability and unique properties, such as water resistance, construction properties and heat insulation, they are The scope of application is extremely broad.

The viscosity of HPMC is inversely proportional to the temperature, that is, the viscosity increases with the decrease of temperature. The viscosity of a product usually refers to the test result of its 2% aqueous solution at 20 ℃.

As the size of the tiles increases, hollowing is more and more likely to occur after laying, and even the accident of the tiles falling off occurs. This problem has a lot to do with the flexibility of the bonding material.

HPMC with uniform reaction, methoxy and hydroxypropyl groups are uniformly distributed, and the water retention rate is high.

Excellent temperature stability: As a non-ionic thickener, the viscosity of HPMC-thickened surfactant system is relatively stable with temperature changes, while the system adding Nacl as a thickener will have a jelly phenomenon at low temperatures.

HPMC cellulose is a synthetic polymer chemically modified from natural cellulose. It is composed of part of the hydroxypropylmethyl (Hypromellose) groups in the natural polymer chain of cellulose. This compound is a white to off-white powder with good solubility in water to form a transparent colloidal solution.

Polycarboxylate Superplasticizer Powder adopts a new synthetic preparation process. The water reduction rate of polycarboxylate polymer powder is as high as more than 40%. It can be used in mortars of various cement gelling formula systems and gypsum gelling formula systems. Polycarboxylate ether superplasticizer can give mortar products excellent The working performance and flow performance can significantly improve the quality of cement-based materials and gypsum-based materials.

In order to improve the brittleness, high elastic modulus and other weaknesses of traditional cement mortar in mortar, it is usually necessary to add additives such as VAE Re-dispersible Polymer Powder. VAE copolymer rdp can give cement mortar better flexibility and resistance. Tensile bonding strength to resist and delay the occurrence of cracks in cement mortar. Since the polymer and mortar form an interpenetrating network structure, a continuous polymer film is formed in the pores, which strengthens the bonding between aggregates and blocks the mortar. There are some pores inside, so the performance of the hardened modified mortar is greatly improved compared to that of cement mortar.

1. The visual state of pure HPMC is fluffy and the bulk density is small, ranging from 0.3-0.4g/ml; the adulterated HPMC has better fluidity and heavier hand feel, which is obviously different from the original appearance.

In ready-mixed mortar, the addition amount of HPMC is very low, but it can significantly improve the performance of wet mortar and is a major additive that affects the construction performance of mortar. Reasonable selection of cellulose ethers of different varieties, different viscosities, different particle sizes, different viscosity degrees and added amounts will have a positive impact on improving the performance of dry mortar.

VAE Re-dispersible Polymer Powder is dispersed in the gypsum slurry and then forms a film, filling the pores of the slurry and intersecting with the gypsum hydration products to form a three-dimensional network structure, making the gypsum structure more dense.
