HEMC Hydroxyethyl Methyl Cellulose
Product overview
Hydroxyethyl Methyl Cellulose (hydroxyethyl methyl cellulose) is a chemically modified cellulose derivative that appears as a white or white-like powder.
product characteristics
1. Good water solubility: it can be quickly dissolved in water to form a uniform and stable solution.
2. The thickening effect is remarkable: it can effectively increase the viscosity of the solution and improve its rheological properties.
3. Strong water retention ability: helps to maintain the water in the system and reduce the loss of water.
4. Good acid and alkali resistance: maintain stable performance in a wide pH range.
5. Wide compatibility: It is compatible with a variety of other additives and ingredients.
product use
1. Construction field: In putty, mortar and other products, as a thickening agent, water retention agent and binder, improve construction performance and product quality.
2. For example, in tile glue, the bonding force can be enhanced to prevent the tile from falling off.
3. Paint industry: Improve the rheology and stability of paint, prevent pigment precipitation.
4. Such as in water-based paint, the paint is easy to paint, and the coating is uniform.
5. Daily chemical products: used for shampoo, body wash, etc., to increase the consistency and stability of the product.
6. Oil exploitation: as an additive to drilling fluid to improve the performance of drilling fluid.
Production process
It is usually made from cellulose by etherification with ethylene oxide and chloromethane.
Market prospects
With the increasing demand for high-quality additives in various industries, Hydroxyethyl Methyl Cellulose has a broad market prospect. Especially in the green development trend of the construction and coating industry, its environmental protection and high performance characteristics make it have greater development potential.
use precautions
1. Storage should be kept dry and ventilated to avoid moisture and high temperature.
2. When dissolved, it should be gradually added and stirred to ensure full dissolution and avoid agglomeration.
3. When using, the amount of addition should be reasonably controlled according to the specific application and formula requirements.
In short, Hydroxyethyl Methyl Cellulose, with its excellent properties and wide range of uses, plays an important role in many fields, providing strong support for the quality improvement and performance optimization of related products.
