Degree is less than 25um, and ultrasonic frequency is 50-70MHz, adds active solvent and bactericide, with rotating speed 600-800rpm stirrings point
5min is dissipated, mian paint is obtained；
(3) raw material is weighed by following mass percent：Butyl acetate 30%, styrene 40%, acetone 25%, long-chain chlorohydrocarbon
5%, by four kinds of raw material components mixing and stirrings, obtain diluent；
(4) by mian paint:Diluent:Initiator:Accelerator=100:50:2-3:The quality proportioning of 1-2 weighs each component, will dilute
Agent is added in mian paint, is stirred, and adds initiator and accelerator, stirs 30min, that is, obtain one kind and exempt to polish unsaturated poly-
Ester transparent priming.
