西班牙语How to adjust the temperature of the fully automatic bottle blowing machine
When processing with a fully automatic bottle blowing machine, it is important to pay attention to temperature control to ensure the production of suitable plastic bottles:
1. Non flowing temperature: Add a certain amount of plastic to the material barrel at the upper end of the capillary rheometer mold, heat it to a certain temperature, maintain a constant temperature of 10 minutes, and apply a constant pressure of 50 MPA. If the material does not flow out of the mold, increase the material temperature by 10 degrees after pressure relief, hold it for 10 minutes, and then apply a constant pressure of the same size. Continue until the melt flows out of the mold, and reduce this temperature by 10 degrees to determine the non flowing temperature of the material.
2. Melting temperature TM: is the lower limit of the processing temperature for crystalline polymer molding.
3. Glass transition temperature TG: is the upper limit of the working temperature of the product.
4. Flow temperature TF: is the lower limit of the processing temperature for amorphous plastics.
5. Decomposition temperature TD: refers to the temperature at which a polymer in a viscous flow state undergoes further degradation of the molecular chain as the temperature increases, rising to the point where the polymer molecular chain undergoes significant degradation.
