Coating technology: Determination of electrodeposition

Core tips: 1 Electrophoretic coating deposition instrument, equipment and materials: Tinplate 50mm × 120mm × 0.2-0.3mm Balance: sensitivity 0.001g Steel ruler: component 1mm 2 Determination of deposition of electrophoretic coating: a Take three tinplate, according to hg2-1046-77 preparation method of electrophoretic paint film, after surface treatment of the test plate, weigh it on the balance to the accuracy of 0.001g b According to the Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: 1 Electrophoretic coating deposition instrument and materials: Tinplate 50mm × 120mm × 0.2-0.3mm balance: sensitive 0.001g steel ruler: component 1mm 2 Electrophoretic coating deposition measurement method: a Take three tinplate, according to hg2-1046-77 preparation method of electrophoretic paint film, after surface treatment of the test plate, weigh it on the balance to the accuracy of 0.001g b Prepare the paint film of the above test plate in turn, then cool it to room temperature in the dryer, weigh it on the balance, and the accuracy is 0.001g c Measure the width and height of the test plate with a steel ruler to the nearest 1mm d Calculation: deposition D (g / M 2) is calculated according to the following formula: D = (g1-g) / 2WH × 104, in which: G1 - weight of test plate after painting, G G - weight of test plate before painting, G W - width of test plate, CM H - height of test plate, CM E test results and errors The average value of three parallel tests shall be taken as the test result, and the difference between the value of each test and the average value shall not exceed 5% Otherwise, it shall be determined again Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
