-Extremely low ash content can provide a very dense internal structure after calcination, while delicate rounded surface of product.
 
6. JOINT FILLER
-Workability: it can provide the suitable viscosity, which has a good plasticity and easy to work.
-Water retention: Qingquan product can make the slurry fully hydreated, which extend the wording time and avoid adhesion on the surface for the slurry and not sag.
 
7. SELF-LEVELING MORTAR
-Prevention of bleeding
-Maintain fluidity, reprove water retention
 
8. TILE ADHESIVE

-Improve the wettability of mortar

Physical properties:

This product is a non-ionic cellulose ether, white powder in appearance, odorless and tasteless, soluble in water and most polar organic solvents and appropriate proportions of ethanol/water, propanol/water, dichloroethane, etc. Diethyl ether, acetone, and absolute ethanol are insoluble, and swell into a clear or slightly turbid colloidal solution in cold water. The aqueous solution has surface activity, high transparency and stable performance. HPMC has thermal gel properties. The product solution forms a gel after heating, and then dissolves after cooling. The gel temperature of products with different specifications is different. The solubility changes with the viscosity. The lower the viscosity, the greater the solubility. There are certain differences in the properties of different specifications of HPMC. The dissolution of HPMC in water is not affected by the pH value. Granularity: The pass rate of 100 mesh is greater than 100%. Bulk density: 0.25-0.70g/ (usually about 0.4g/), specific gravity 1.26-1.31. Discoloration temperature: 180-200ºC, carbonization temperature: 280-300ºC. HPMC has the characteristics of thickening ability, salt drainage, pH stability, water retention, dimensional stability, excellent film-forming properties, and wide range of enzyme resistance, dispersibility and adhesion.

Hpmc Features:

1.Appearance: HPMC is a white to light yellow powder or granular product
2.Solubility: HPMC is nearly insoluble in anhydrous ethanol, ethyl ether and acetone. It is swelled in cold water to form a transparent or a slight cloudy solution. HPMC can be dissolved into some organic solvents and also in water-organic solvent mixed solvents.
3.Graininess:The product particle size is greater than or equal to 80mesh.
4.With reduction of methoxyl groups content, HPMC is increased in gelling temperature and decreased in water solubility and surface activity.

In order to allow everyone to better understand the different uses of hydroxypropyl methylcellulose, Qingquan Fiber has sorted out some application industries for everyone, and hydroxypropyl methylcellulose can be used as building materials. Coating industry, ceramic industry, medicine, food, textile, agriculture, makeup and other industries.

Gypsum-based plastering application (NDJ) 50000-150000mpa.s (brookfield)30000-550000
Water retention: Qingquan cellulose can retain the moisture in the mortar and make the gypsum completely solidified. The higher the year of the solution, the stronger the water retention capacity. On the contrary, the weaker the water retention capacity.
Anti-sagging property: allows the builder to apply a thicker coating without causing building ripples.
Mortar yield: For a fixed weight of dry mortar, the presence of Qingquan cellulose can produce a larger wet mortar volume.

Self-leveling mortar application (NDJ) 400-10000mpa.s (brookfield)400-10000
Prevent bleeding: Qingquan cellulose can play a very good suspension around, preventing slurry precipitation and bleeding.
Maintain fluidity and improve water retention: The low-viscosity Qingquan cellulose will not affect the fluidity of the slurry and is convenient for construction. At the same time, it has a certain degree of water retention, which makes the surface effect after self-leveling good and avoids product cracks.

Jointing agent application (NDJ) 100000-200000mpa.s (brookfield) 45000-650000
Workability: Cellulose provides qualified viscosity, good plasticity and easy construction.
Water retention: Cellulose can fully hydrate the slurry, prolong the construction time and avoid product cracking.
Anti-sagging: Cellulose can make the slurry adhere firmly to the surface without sagging.

Tile Adhesive (NDJ) 100000-200000mpa.s (brookfield)45000-650000
Water retention: Qingquan cellulose can reduce the water absorbed by the substrate and tiles in the mortar. Keep the moisture in the adhesive as much as possible, so that the mortar is coated for a long period of time after being thrown to maintain the adhesion. Significantly prolonged opening time can enable workers to coat a larger area each time and improve construction efficiency.

Improve bonding strength and anti-slip performance: Qingquan cellulose can ensure that tiles will not slide during construction, especially for heavy tiles, marble and other stones.

Improved working performance: The lubricating performance of Qingquan cellulose significantly improves the working performance of the mortar, making the mortar easy to flow and smear, and improve working efficiency.

Improve the wettability of the mortar: Qingquan cellulose imparts the consistency of the mortar, improves the wetting ability of the mortar with tiles and substrates, and improves the bonding force of the wet mortar, especially for high water-cement ratio formulations.
