With the advances in catalyst technology, now appears directly from the polymerization kettle was obtained without further granulated spherical PE resin
technology. Direct production need not
Pelletized resin, not only eliminating the need for a large number of energy-intensive steps such as extrusion granulation, and the low-crystalline product
obtained from the reactor does not occur morphological changes, thus advantageously
In shorter processing cycle, saving processing energy. Spherilene process using a titanium-based catalyst supported on MgCl2 on directly from the reactor to
produce a density of
0.890-0.970g/cm3 PE spherical particles, including LDPE, LLDPE and HDPE, even without reducing the production capacity of the case production VLDPE and
ULDPE. By eliminating the granulation process, the the device investment can be reduced by 20%. The process slurry method prepolymer gas fluidized bed
technology combined reaction
First in a small loop reactor, and then the prepolymer is continuously passed through one or both of the short residence time of the gas phase fluidized bed,
the two gas phase fluidized bed controllable
System and maintained completely independent of gas composition, temperature and pressure can be independently controlled to achieve a greater flexibility in
Spherilen core of the process is its catalyst technology. The technique uses a spherical titanium based catalyst on the physical and chemical structure
shows a three-dimensional space
Characteristics can be artificially controlled physical and chemical properties of the carrier itself, and controls the distribution of the active center on
the carrier. The principle is: by controlling the pores of the carrier
Rate, so that the active center preferentially distributed on the surface, resulting in the monomer diffusion limited the ability of layered or hollow
polymer particles can be obtained, so that during the polymerization
, While the particle itself has become a reactor, the introduction of other monomers which may be in the role of the active center of the hollow interior of
the particles under polymerization or copolymerization, thereby
Produce very uniformly dispersed polymer blend or polymer alloy. Using different monomer formulations to obtain a homopolymer, copolymer, elastomer, and its
It functional polymer.
Particles made of plastic, the first to collect waste plastic; then classify category includes color classification and the classification of varieties;
after that to the mill
Where pulverized, for cleaning; comminuted after cleaning, to the extruder for extrusion, extruded into strips, and then cut into pellets; particle cut, is
to do plastic
The raw materials of the material products.
After the processing of this equipment, the original waste plastic unsightly immediately into a colorful plastic particles. These recycled plastic
granules still has
Good material properties to meet blown film, drawing, trombone, casting, extrusion shaped timber and other technical requirements, widely used in the
production of plastic products. After
Over the further processing of plastic products enterprise, they become our common plastic pots, folders, plastic film, agricultural and industrial machinery
parts. These products are
The use of a wide range of become the darling of the market.
pellet making machine production, less investment, small-scale, not form secondary pollution, is to meet the social needs of the industry. Promote the waste plastic
granulator Old plastic is an important resource. Less ubiquitous plastic garbage processing income increased.
The price of recycled plastics, and only 50% of the new plastic, has a great competitive advantage. Since 2000, China's annual imports of waste plastics
from abroad 200
Tons, and the annual increase rate of 10%. Domestic waste plastics in 2004 alone reached 11 million tons, the vast majority are not being utilized, and new
Plastic raw materials is still a steady stream of put into use.
