First, the solids content of the determination and maintenance of: 1. Drying weighing method Description: This parameter was measured to be regularly used to control the amount of resin cylinder available. Usually based on this number be added. Measurement Method: 1. Prepare a clean aluminum pan, accurately weighed (A); 2, take 1-5ml bath, adding an aluminum pan, accurately weighed (B); 3, a standard drying conditions: 105 ℃ · 3 hours and accurately weighed (c) after drying; b fast drying conditions:. 160 ℃ · 30 minutes (this drying method of production only as reference data), accurately weighed (c C after drying - A solid content = --------- × 100% B - A normal solids content should be maintained at the level of 8-12% of the solids content will result in low deposition rate is too low, the film formation of decline, so is bound to decrease the operational stability of the working cylinder solids content usually does not cause any harm too high, but it is clear that the loss will increase with the solids content of the maintenance is essential, not only to provide the basis for the production of supplements added and, in the event of problems, it should first determine solids content is within the normal range of supplements: supplements solids by adding paint concentrate to be specific as measured by the amount of numerical calculations B × (CD) A = ----------- E where: A = the required additional EC-3001 paint concentrate volume (L) B = working tank volume (L) C = required solids content (% ) D = conventional solid content was measured (%) E = applied paint concentrate solid content (%)
