Chemical types: liquid and solid form, usually in liquid and solid form, usually in the form of concentrated which often mixed with new plastic or already premixed. Where detergents are put into the machine and soaked in long enough to activate cylinders chemical reaction. This chemical reaction circuit denatured polymer molecules need to be cleaned and the new plastic is very susceptible to subsequent ejected. Chemical cleaners are effective, but high prices and long soaking time. Some chemical cleaners Ammonia odor born and some other odors that are harmful to health. In addition, chemical cleaners need time long soak in the machine and high temperature polymers can be decomposed, can cause corrosion of machinery.
- Mechanical type, abrasion: This type of detergent at a concentration high but can be supplied pre-mixed form. Delivery system loaded with a high content of glass beads, inert fillers. This system cleaning detergent by strong scouring the cylinder and screw. Scouring the powerful and high filler content will wear small tolerances between the screw and the cylinder, but this kind of cleanses will wear faster than conventional screw. This type of detergent does not flow, can explode when tiny high-temperature processing or through nozzles or small stove top, they could jeopardize the equipment because pressure acting on the upper machine and flammable .
- type body / non-corrosive thermoplastic: bleach compound group this shaft as well as the easiest to use safety equipment, machinery.
