ASA Cast Film Production Machine Good Weather Resistance Uniformity
Extensibility And Crease Resistance
1.Introduction of ASA film
ASA is a copolymerization of styrene, acrylonitrile and acrylic
rubber. Technically speaking, ASA not only maintains the main
characteristics of ABS, but also combines the advantages of acrylic
weather resistance, so that the application of the product can be
extended to outdoor use. ASA film products are made of high content
of ASA rubber powder raw materials. The products have completely
passed the 12,000-hour weather resistance test. The color retention
performance is many times higher than that of the current
co-extruded materials on the market. The uniformity of ASA film is
higher than that of co-extruded material, there is no color
difference of thin spots, and no waste of scraps. Therefore, the
ASA cast film has become a development trend at this stage.
2. Application of ASA film
Because ASA film has good weather resistance, uniformity,
extensibility and crease resistance, it is widely used in roof
color steel tiles, resin tiles and plastic sheets, sheet surfaces,
outdoor plastic lounge chairs, outdoor lamps and lanterns surface
coating and advertising board, decorative board.
3. The equipment features of the ASA cast film production line
produced by our company
(1) The whole set of equipment adopts PLC, closed-loop control so
it can realize one-key speed increase and is easy to operate.
(2) The special screw design of the extruder ensures that the
melting of the raw plastic material, the color of the product is
uniform, and the extrusion volume is high
(3) The full-automatic mold combined with the thickness gauge can
more effectively fine-tune the melt thickness deviation in the
transverse width of the die, and the thickness uniformity is
guaranteed to be ±10 um.
(4) The casting roll adopts the method of integral machining of the
inner runner to ensure the temperature control within ±1 degree,
and the rolling surface control accuracy within± 10um to ensure
more accurate casting film thickness.
(5) The tension sensor and control system are used to ensure the
tension control is ± 10um.
(6) A complete set of servo motors and servo controllers make the
equipment run more accurately.
(7) The fully automatic cutting and rewinding machine has two
functions: contact rewinding and gap rewinding. The winding tape
has tension control, the adjustment range is 5-200N/M.
