Sandwich Panel Production Line Cold Room PU Foam Sheet Making
1.Beautiful and applicable,multiple functions,such as thermal
isolation,sound isolation and flame retardence.
2.Using heated air recycle oven,strictly control the temperature of
PU foaming and solidification in suitable range.
3.Using high pressure foaming system,precise measurement,high
stabilith,little dust in locale,protect the worker's health.
4.Using 141B Or C5 as foaming agent.Insted of carbon
chloral-fluoride,make the PU foaming treatment treatment become
environmental production crafe.
5.Special double belt cojveyor,flat surface of sandwich panel,even
6.Operation system controlled by PLC computer,personal design and
Our company offers professional polyurethane PU and EPS foaming
sandwich panel production line. The sandwich panel is composed of
two-layer forming metal panel (or panel made of other materials)
and high polymer heat insulation inner core, which is made by
direct foaming between panels and then maturation forming. In this
way, this kind of panel is easy for installation, and it enjoys
light weight and high efficiency. Besides, the filling system also
adopts closing bubble molecular structure, thus condensation of
water vapor is avoided.
