Product raw material control

Product quality is the most concerned issue for users, especially the use of HPMC in the gypsum product industry requires not only good quality but also stable quality. This is our first major event in production management.

The production of cellulose ether has strict requirements on raw materials, especially refined cotton. HaShuo Chemical Purchasing Department has a special raw material supplier audit system to ensure the stability and reliability of incoming raw materials.

Production line control

In the cellulose ether production stage, from the pulverization of refined cotton, the bulk density of refined cotton after pulverization is strictly controlled. We use standardized processes to control various indicators of the production products, design different process conditions according to product technical requirements, and realize DCS automatic control.

For each batch produced, the feeding amount is accurately measured, the solvent ratio is strictly controlled, and the reaction process is controlled by the computer to reduce human error.

Quality inspection analysis control

The finished product is a two-level analysis, which is divided into single batch control and finished product control. A single batch of products can be mixed into a finished product after being tested and analyzed. All the indicators of the finished product must be tested and qualified before being packaged and stored.
