Product Description
The purpose and characteristics of PP sheet production line
PP board, also known as polypropylene (PP) board (PP pure board, modified PP board, reinforced PP board, PP welding rod).
The hanger type die head of the PP sheet production line adopts a special double flow design, which makes the adjustment of sheet thickness more accurate. Temperature control can accurately control the plasticization process and the thickness and flatness of the board.
The purpose and characteristics of the PP sheet production line are:
The screw adopts special mixing function and high plasticizing capacity design.
The 2-hanger mold adopts a special double flow design, making the adjustment of the thickness of the board more precise.
3. Temperature control can accurately control the plasticization process and the thickness and flatness of the board.
The 4-roll calender adopts horizontal, vertical or 45 degree tilt type.
The PP sheet production line is a semi crystalline material. It has a harder texture and a higher melting point than PE. Combining the superior chemical resistance, heat resistance, and impact resistance of PP sheet materials, it has been widely used
More and more industries are using it, and its application areas are becoming more and more extensive. At present, it is mainly used in flooring, electronics, packaging, machinery, light industry, postal services, food, home appliances, advertising, decoration, and culture
Supplies, optical and magnetic technology, biotechnology, automotive interior and other industries.
So how is PP sheet produced? Below, I will give you a brief introduction:
Firstly, PP resin particles are used as the main raw material, along with various plastic additives and small materials. After being melted at high temperature by the main machine and extruded by the extruder, it is then shaped by five rollers and cooled in the cooling bracket
Cutting edges, pulling out the board by a tractor, then cutting and cutting to the desired size, and stacking the materials on the feeding platform.
The process flow is: formula - mixing - extrusion - shaping - traction - cutting - unloading.
The PP sheet production line adopts a specially designed SJ series single screw extruder, which is driven by DC speed regulation and imported temperature control instruments. It has a wide speed regulation range, high temperature control accuracy, and easy and reliable operation
advantage. The auxiliary machine consists of a vacuum shaping table, a traction machine, and a cutting machine level pushing frame. Equipped with a large forced cooling device for the shaping effect of the board. Crawler type tractor adopts correct deceleration motor and frequency conversion
The device has the advantages of reasonable structure, high traction force, and stable traction. The cutting machine has reliable operation; The advantages of correctness and high cutting accuracy are that the feeding rack is equipped with a movable feeding trolley and a specially designed one
The rubber protective layer has the advantages of not damaging the material and easy to use. The auxiliary unit adopts programmable computer control or domestic control system, and the overall control is reliable and stable.
Our company has developed a new production line technology for PP sheet materials, which enables the extrusion of substrates, color layers, and wear-resistant layers to be completed simultaneously on the same equipment. Equipment that can reduce surface treatment patterns and is wear-resistant. minus
Less labor and equipment investment greatly reduces the production cost of PP sheet materials, and a set of automated assembly lines only requires one person to operate the feeding port and one person to operate the main computer screen,
The basic standard for achieving automated production. The core technology of this product, equipment precedent, high degree of automation, belongs to the domestic pioneering technology.
