Product Description

This production line is used to produce sandwich panels for making automatic doors with the middle layer of rigid polyurethane foam and with aluminum sheet or colorsteel sheet as the top and bottom face layers. The laminated panel is between *0 and **0 mm in thickness, **0~**0mm in width, length determined by the customer. 1.Brief introduction Low-pressure reaction injection machine of two components is a kind of specialized equipment used for making various PU plastic products. Its operation principle is as follows: Liquid monomers or pre-polymers, in accordance with a certain blending ratio, are delivered into the mixing head to agitate sufficiently and injected into mould. Then the mixed material shall react and harden into shape, waiting for ripening and demoulding. 2.Constituents of the equipment (Click on the name of each part to see its picture.) Low-pressure reaction injection machine is consisted of mixing head, loading tanks, metering pump unit, hot-water circulating system, cleaning installation, base, supporting frame for mixing head, electrical control cabinet and so on. 3.Technical parameters Mixing ratio A:B=2.5:1 A:B=1:1 Or in accordance with technical requirement Range of throughput (gms/sec) 7~***0 5~***0 7 scales in total, see throughput list for details Volume of loading tank (L) *0~**0 *0~**0 *0 **0 **0 **0 **0 Revolution of mixing head (rpm) ********0 ********0 Program-controlled points *2 *2 *0 points or **0 points if on request Viscosity requirement (CPS) <***0 <***0 Temperature adjusting range(Celsius) ***0 ***0 Total power(kw) 9~*8 9~*8 6 kw for heating Form of mixing head assemblyCrane or Overhead travelling External dimensions(m)Length×Width×Height 3.0×1.5×2.3 4.4×1.8×3.0 (for tank of **0L)
