______ incorporation of zinc phosphate powder into the liquid and mixing over a ______ area of a cooled glass slab are recommended because the chemical reaction is exothermic and produces heat.

Question

Quizplus · Accepted Answer

Incremental incorporation of zinc phosphate powder into the liquid and mixing over a large area of a cooled glass slab are recommended because the chemical reaction is exothermic and produces heat.Incremental incorporation of the powder into the liquid allows for controlled dissipation of heat.Mixing over a large area of a cooled glass slab also dissipates the heat.The glass slab should be cooled to be effective in dissipating the heat but not below the dew point when water condensation would lessen the incorporation of powder and shorten the setting time.
