Hydroxyethyl cellulose manufacturers teach you how to use hydroxyethyl cellulose: add it directly in production - this method is the simplest and takes less time.

High clean water should be added into the drum and prepared with a large agitator. Start stirring at low speed and slowly sieve the hydroxyethyl cellulose into the solution. Continue stirring until all particles are wet. Then add preservatives, various additives. Such as pigments, dispersants, ammonia, etc. Stir until all hydroxyethyl cellulose is completely dissolved (the viscosity of the solution increases significantly) before adding other components in the formula for reaction.

Hydroxyethyl cellulose was prepared with mother liquor.

The mother liquor with high concentration is prepared first, and then added into the product. The advantage of this method is that it has greater flexibility and can be directly added to the finished product, but it must be properly stored. This method is similar to most of the steps in method 1. The difference is that no high shear agitator is needed, and only some agitators with enough power to keep hydroxyethyl cellulose uniformly dispersed in the solution can be used, and the stirring can be continued until it is completely dissolved into a viscous solution. However, it must be noted that the fungicide must be added to the mother liquor as soon as possible.

Hydroxyethyl cellulose manufacturers teach you the role of hydroxyethyl cellulose in waterborne coatings.

Hydroxyethyl cellulose is a nonionic surfactant, Besides thickening, suspension, adhesion, floatation, film forming, dispersing, water holding and providing protective colloid, it also has the following properties: hydroxyethyl cellulose HEC can be dissolved in hot water or cold water, high temperature or boiling without precipitation, so that it has a wide range of solubility and viscosity characteristics, and non thermal gelation; HEC water retention capacity is twice as high as methyl cellulose, and has better flow regulation. The results showed that HEC had the worst dispersing ability compared with the commonly recognized methyl cellulose and hydroxypropyl methyl cellulose, but it had the strongest protective colloid ability; its non-ionic type could coexist with other water-soluble polymers, surfactants and salts in a wide range, and was an excellent colloidal thickener containing high concentration electrolyte solution.

Shandong chuangyao Biotechnology Co., Ltd. reminds you that, since the surface treated hydroxyethyl cellulose is a powder or fibrous solid, when equipped with hydroxyethyl cellulose mother liquor,

1. When using high viscosity hydroxyethyl cellulose, the concentration of mother liquor should not be higher than 2.5-3% (weight meter), otherwise, it is difficult to operate the mother liquor.

2. Before and after adding hydroxyethyl cellulose, the mixture must be kept stirring until the solution is completely transparent and clear.

3. It is necessary to slowly sieve into the mixing drum, and do not enter into the mixing drum in large quantities or by the way of block and globular and hydroxyethyl cellulose.

4. The water temperature and pH value in water have a significant relationship with the dissolution of hydroxyethyl cellulose, and special attention should be paid to.

5. As far as possible, add mould inhibitor in advance.

6. Never add some alkaline substance to the mixture before the hydroxyethyl cellulose powder is wet through by water. The pH value can be increased after the moisture is wet, which helps to dissolve.
