The choice of waste plastic crusher machine mainly depends on the type of material to be crushed, the shape and the degree of crushing required, different materials of waste plastics should be used to crush different equipment. Hard PVC, polystyrene, organic glass, phenolic resin, urea-formaldehyde resin, polyester resin, etc. is a class of brittle plastic, brittle and fragile, once subject to compression, and impact force, very easy to brittle crack, broken into small pieces, for this type of plastic suitable for compression or impact crushing equipment for crushing;
For ductile plastics with high ductility at room temperature, such as polyethylene, polypropylene, polyurethane, ABS plastic, etc., is only suitable for shear-type crushing equipment, because they are subject to external compression, bending, impact and other forces, generally will not crack, it is difficult to break, it is not appropriate to use brittle plastic crushing equipment; In addition, for elastic materials, soft materials, it is best to use low-temperature plastic crushing machine.
In addition, according to the degree of the waste that needs to be crushed to determine the crushing equipment, if the large pieces of crushing into small pieces should be used compression, impact or crushed waste plastic crusher; if the small pieces of crushing into fine powder, fine particles, the main use of waste plastic crusher machine.
Scrap material due to the impact of external conditions and the role of light and heat, there have been different degrees of aging, obviously, a variety of additives also have different degrees of loss. In order to improve the quality of recycled products as much as possible, a certain amount of additives need to be added in the remanufacturing process, so as to improve the multifaceted performance of the return material molding process and products.
Based on consideration of some of the above factors, the following points should be taken into account when determining the formulation of remanufactured products.
1, The choice of additive type.
2, the determination of the number of additives added.
3, Adjustment of the formulation.
