Classification and scope of application of blow molding
Polymer mixing equipment is defined as a process by which a polymer or polymer system is advanced through melt mixing. The mixing process of empty plate has a wide range of planning from the addition of a single additive to the treatment of multiple additives, polymer alloys and reactivity mixing. It is estimated that one-third of the polymer produced for blow molding in the United States is through blending. The mix can be customized according to the functional requirements of the application. Blend products with hybrid features such as high gloss and excellent impact strength, eva foam products or fine molding and outstanding stiffness.
The blended polymer is usually cut into pieces for further processing. However, there is growing industry interest in combining mixing with further processes, such as profile extrusion, which prevents the polymer from being reheated.
Various types of melt mixing equipment are used, from roller mixers and batch mixers to single and twin screw extruders. Continuous mixing (extruder) is the most commonly used equipment, because it can provide a common quality of the product, and can reduce operating costs. There are two types of mixing: Distributed mixing materials can be evenly distributed without high shear stress in mixing. This type of mixture is called extensional mixing or laminar mixing.
Lax mixing is also called strong mixing, in which high shear stresses are applied to break up cohesive solids. For example, when additive pellets are broken, the practical particle size becomes smaller.
Mixing operations often require two mixing types in a process.
