4. TECHNICAL CONDITIONS OF EACH SYSTEM:
   1. A SET OF 400L VACUUM MIXING DEGASSING TANK

Technical specification and application of tank

The effective volume is 400L

Heat conduction oil 10KW

Ultimate vacuum: 50Pa (no load, cold state)

No load leakage rate: 50Pa.L/S

Operating temperature: 60 ~ 80℃

Tank surface temperature Ambient temperature +20℃

Equipped with frequency control device, can adjust the stirring lifting speed according to the viscosity of the material;

Rock wool insulation, stainless steel plate (SUS430, 1.5mm thick) armored, surface coating

This tank is used for mixing epoxy resin and curing agent mixture and vacuum degassing.

The mixing tank is installed on the pouring master side of the vacuum pouring tank to increase production.

4.4 TWO SETS OF VACUUM SYSTEM (A TOTAL OF 3 VACUUM PUMPS):

4.4.1. The maximum pumping speed of a rotary sheet Roots unit to the pouring tank vacuum unit is 300L/S. The working vacuum of the system can be controlled between 50-200Pa; Reduce the possibility of material being pumped into the vacuum system due to high vacuum degree; The system is equipped with 2 sets of special filters to prevent impurities in the pumped gas to the maximum extent and capture condensing condensable gas to protect the vacuum pump.
