| Abstract: | Attempt has been
made to find utilization of gummy mass, a by-product of lac-based industry.
High thermal resistant baking type insulating varnishes have been developed
based on gummy mass and synthetic resins. These varnishes possess all the basic
requirements as per IS:10026-1982. The performance of one of the varnishes was
found to be satisfactory by a local consumer when applied on the coils of a
220kW 6.6 kV electric motor. Gummy mass was further attempted for use as an
extender in polyester resin based sheet moulding compound (SMC) for preparing
fibre-glass reinforced (FRP) sheets. The FRP sheets thus prepared by hand
lay-up technique and curing in the cold, possessed good mechanical properties
and moderate resistance towards various chemicals. Gummy mass, being cheaper
compared to polyester resin, appears to possess potential for utilization in
the above fields. |
