In general, there are about three more common ways of using hydroxyethyl cellulose. These are listed here.
(1) Directly at the time of production
1. Add clean water to a large vat equipped with a high pressure stirrer.
2. Start stirring continuously at low speed and slowly sift the hydroxyethyl cellulose into the solution.
3. Continue stirring until all granules are wet.
4. Then add mould inhibitors, alkaline additives such as pigments, dispersion aids and ammonia.
5. Stir until all the hydroxyethyl cellulose is completely dissolved (viscosity of the solution increases significantly). Then adding the other components of the formulation and grinding until the finished product is ready.
(2) Equipping master batch for waiting use
This method is to equip the master batch with a higher concentration before adding it to the emulsion paint. The advantage of this method is that it is more flexible and can be added directly to the finished product, but should be stored properly. The steps are similar to parts 1-4 of method 1, except that it does not require high mixing until it is completely dissolved into a viscous solution.
(3) Forming a porridge for use
Since organic solvents are not good solvents for hydroxyethyl cellulose (HEC), it can be used to prepare porridge. The most commonly used organic solvents are organic liquids in paint formulations such as ethylene glycol, propylene glycol and film formers such as ethylene glycol or diethylene glycol butyl acetate.
Ice water is also a poor solvent, so it is often used with organic liquids to prepare porridge. Porridge-like hydroxyethyl cellulose (HEC) can be added directly to the paint as it is fully absorbed. When added to lacquer, it dissolves instantly and acts as a thickener. After adding the varnish, it must be stirred continuously until the hydroxyethyl cellulose is completely dissolved and uniform. Generally, 6 parts of organic solvent or ice water and 1 part of hydroxyethyl cellulose are mixed to make porridge, which will be hydrolyzed and rise significantly after about 6-30 minutes. In summer, the water temperature is generally high, so it is not suitable to use porridge.
The above is the general content of the three methods of use of hydroxyethyl cellulose, I believe we also have a preliminary understanding of this.
