CaCO3 Filler Masterbatch granulator extrusion temperature is difficult to control
In the country, CaCO3 Filler Masterbatch granulator use most of the mixer with forced side feed single screw extrusion granulation, screw length to diameter ratio should not be short, because the rubber in the extrusion process heat, the screw Long, the greater the friction coefficient, the extrusion temperature is not easy to control, which is a major problem of rubber masterbatch granulation.
It is the biggest technical characteristics: the use of the whole process of cold processing to prepare a new process, with a lower processing temperature, to avoid the emergence of rubber additives after melting and then destroy the original refinement of the particles of the standard particles, the maximum limit to ensure that the formula " Refinement of solubilization "features. CaCO3 Filler Masterbatch granulator extrusion temperature is difficult to control.
At present, the domestic masterbatch granulator temperature control system is divided into two kinds, one is the pipeline around, this cooling system that is through the copper tube around the barrel into the cooling medium. The other only jacket type, this cooling system is more independent, and extrusion barrel planning for the jacketed hollow external cooling medium, compared with the previous a significant temperature control effect.
Masterbatch granulator screw with modular design and manufacture of the principle. According to the processing material system and process formula requirements of its aspect ratio, barrel structure, screw arrangement, for network structure, the number and location of exhaust, feeding methods, electrical control, etc., can be optimized and rational configuration. To achieve multi-functional, multi-purpose to adapt to the processing of polymer materials to take full advantage of the limited space design The latest involute spline form of structural core, to ensure maximum carrying capacity to achieve high torque transmission; the use of computer-aided design of the threaded components Conjugate type.
CaCO3 Filler Masterbatch granulator has a lot of use of space, which is able to reduce the rubber additives in the mixing with the raw rubber when the formation of pollution and loss. Therefore, the energy-saving environmental protection into the new direction of the development of masterbatch granulator, and can be useful to improve the working environment of the workshop staff, with the reduction of powder-like additives lost on the layout of the formula, reduce the rubber mixing time, and then useful The cost of falling products.
CaCO3 Filler Masterbatch specific functions and the use of a very good interpretation of this product, many people are directed at CaCO3 Filler Masterbatch this feature to use, so the specific characteristics or to understand what.
CaCO3 Filler Masterbatch in the manufacture of products can be a good plastic products have better performance, including some features can be very good for the product to provide better sales. Of course, the scope and characteristics of functional masterbatch is also need to know about it.
CaCO3 Filler Masterbatch ordinary CaCO3 Filler Masterbatch compared to the biggest feature is added to the PP, PE, its transparency is small, can be widely used in film, sheet, pipe, container and other fields. As used in PE films, the proper addition can improve the transparency of HDPE films and have little effect on the transparency of LDPE films. While having good surface finish and balanced mechanical properties. These are the existing ordinary CaCO3 Filler Masterbatch can not match. It can be predicted that the emergence of this CaCO3 Filler Masterbatch will have a greater impact on the application of plastic fill and its downstream applications.
(1) good transparency, the amount of 30 copies of light transmission rate is still more than 90%
(2) the loss of mechanical properties is very small, basically able to maintain the main mechanical properties of raw materials
(3) no need to change the original equipment, process conditions
(4) can reduce the product cost 5-10% or more (specific to be based on the amount of added)
