IXPE radiation crosslinked foamed sheet, for the chemical crosslinked foam sheet, A more smooth surface, uniform foam fine, the physical
properties are better than the XPE,Widely used in construction, chemical piping, thermal engineering Vehicle manufacturing, packaging,
sports and entertainment industries.At present the products in the mainland of China in the period of market growth, development
1.XPE crosslinked polyethylene foam coil wire consists of the following four-step production process:
Granulation -- extruding master piece -- foaming molding -- auxiliary winding
One, three common ways of granulation
1. Close refining -- open refining -- pull sheet -- cooling -- grain cutting
2. Intensive refining -- single screw extrusion -- water ring (air-cooled) granulation
3. High speed mixer -- flat double extruder -- single screw extruder -- water ring (air-cooled) grain cutting
Based on many years of XPE screw design and manufacturing experience, our company has been constantly improving the structural design of XPE screw, improving the temperature control and cooling system of the cylinder and the screw, and optimizing the internal structure of the mold
The design adopts vertical mirror three-roller press to form, equipped with high-precision constant temperature system, which makes the XPE master sheet extrusion process stable and continuous, ensuring uniform plasticization and dispersion of materials, and easy to control the temperature.
The foaming furnace adopts a new three-section extended furnace. The furnace body is divided into preheating section, crosslinking section and foaming section. The furnace body is 23 meters long, 5.5 meters high and 3.5 meters wide.
Equipped with famous brand high precision energy-saving burner, ensure the temperature is accurately controlled, can produce XPE, IXPE, rubber and plastic foaming products.
Three main features of the furnace:
1. Low energy consumption: the preheating section and cross-linking section have been greatly changed to reduce the heat capacity space and save energy and reduce consumption when the process requirements are met. , the gas consumption is equivalent to that of two furnaces.
2. Wide range of production process: in terms of the heat distribution in the furnace, the defect of unreasonable heat distribution in the Furnace body in Korea is overcome, and the XPE foaming can be made in a relatively wide range according to the working heat requirements of XPE foaming
The foaming rate is 5-35 times. The foaming rate is full and stable continuously.
3. High output: In the current domestic production of foaming furnace, our three-stage furnace output is the largest, with the maximum of more than 200KG/H, and XPE foam hole is more detailed than that of two-stage furnace.
XPE crosslinked foamed PE roll material line contains the fololwing four - step process :
pelletizing---extrude---- foaming ----winder
ONE、Normal pelletizing method:
1.Banburying ---open mill --zipper pulls---cooling --cutting
2.Banburying---single screw extruder --water circulation (or air cooling)cutting
3.High speed blender--parallel twins screw extruder---single screw extruder--water circulation (or air cooling)cutting
our company's screw design and manufacture based on XPE experience，Continuously improve the structure of XPE screw design, improved barrel and
screw temperature control and cooling systems，On inner Structural Optimization Design of mould，Formed with vertical mirror of three - roll calender,
equipped with high precision temperature control system，Mother makes XPE steady and continuous process of sheet extrusion, ensure the material plasticizing
distributed evenly, easy to control the temperature.
Foaming oven adopts the latest enhanced furnace ,Oven divided into three parts: preheating stage,coil stage , furnace whole length 23meters, high ceiling
5.5 meters, width 3.5 meter.,equipped imported brand high precise burner,Ensure accurate temperature control, can produce XPE, IXPE, rubber and foam
The furnace three major characteristics :
1, low energy consumption :
the preheating period, crosslinking made larger changes, meet the technological requirements, reduce the heat capacity of space and energy consumption. ,
gas consumption and a two - stage furnace.
2, wide range of production processes :
Heat distribution in the furnace, overcome the defects of South Korea's unreasonable distribution of heat in the furnace,
In accordance with the work of the XPE foam thermal requirements, making the XPE foam over a relatively wide range, expansion ratio at 5-35 times, foam
full, continuous and stable.
3, the output is big : In the current domestic production of foam furnace, our three - stage production of the largest and the largest 200KG/H above, and XPE
foam more detailed than the two - stage gasifier.
Four, rewinding auxiliary equipment
The whole length of downstream line is 20m, as from front to back order, it is passed 5 roller calibration unit,air cooling system,smooth surface dealing
device,automatic correction trimming device,haul off unit,double position collector.
The above three parts, foam extrusion, rolling length of 60 meters.
