Small film blowing machine (small film blowing machine, laboratory film blowing machine, experimental film blowing machine)
The utility model relates to a small film blowing machine set with a screw diameter of 20-25, which is mainly applied to the research and development of new materials and the production of thin films
The early detection of the properties of the products after the addition of various additives.
Due to the small size of the film blowing machine screw diameter is relatively small, the shear is relatively weak, less shear heat, blowing
Low pressure film, especially the low melting index of low pressure film, to master the appropriate process
Temperature. General homogenization section, die temperature to 240-250 (Celsius), with melt index comparison
Low and low pressure resin, the temperature can reach 270-280 (Celsius).
Otherwise, the product is not fully plasticized, will produce a lot of crystal points.
