compound consists of two components. It has been delivered
with hardener in sets with mass of: 1.07, 3.21, 6.42 or
12.84 / 1 kg = 0,625 l /. The proper quantities of hardener
have been delivered in separate containers. Both components
should be accurately intermixed. Such mixing process lasts
a few minutes and it has been done by hand with utilization
of drill equipped with a special rabble. Since the commencement
of mixing operation, there remains about 20 minutes until
the creation of the gelation process of composition. The
temperature of mixed components amounts to 15-25°C,
and ambient temperature in close by chocks - minimum 10°C.
The moulds should be poured slowly and
in continuous way until the moment of complete filling up
of mould and top riser. The top riser creates proper hydrostatic
pressure and ensures a reserve of EPY compound for the whole
chock. It guarantees the proper contact of the poured chock
with the bearing surface of machinery frame.
Time of hardening of chock depends on
ambient temperature and amounts to:
72 hours in temperature of 10 °C,
48 hours in temperature of 15 °C,
24 hours in temperature of 20 °C.
