1. Put the materials in accordance with the specified feeding sequence, and generally add the stabilizer first and pour it on the valve.
2. To prevent the occurrence of inequality in cornmeal and mixing. (Generally, after finishing adding powder, the cylinder should be swept first, and then started at low speed. After mixing the powder evenly, plasticizer should be added. Then, the cylinder should be swept before the second refueling, and then the refueling should be started. Before feeding, open the lid and stir at low speed for 1-2 minutes to remove volatiles.
3. The control of feeding time and temperature shall be treated differently according to the different specifications of the glue material. The principle is to ensure that the material is mixed evenly, and the plasticizer is fully absorbed, without cornmeal and without agglomeration. Sweep the cylinder frequently when preparing the material.
4. The process control of the extruder shall be treated differently according to the different specifications of the binder. In principle, the temperature of the binder shall be increased gradually from the feeding section, the compression section, the gelatinizing section and the forming section, and the head temperature may be reduced appropriately under the premise of ensuring the appearance of the binder or strip is bright. The general principle is to ensure that the glue is uniform and good, without raw and cold materials, burning and agglomerating phenomenon.
5. Use and accurately weigh materials strictly according to the formula specified in the project, and do not change the dosage or substitute raw materials without permission.
6. Feeders should pay attention to check the valve frequently to prevent leakage of starch due to poor valve sealing.
