某乡办电镀厂自行配制了一种贵金属防变色涂料，采用以汽油为主的有机溶剂作稀释剂。由于该类溶剂挥发性强、易燃,并在浸涂过程中涂料需要加温至50 ℃，浸涂后还需在110 ℃高温下烘烤。采用该种工艺本应有严格的防
A township electroplating factory prepared a precious metal anti-discoloration paint, using gasoline-based organic solvents as a diluent. Due to the strong volatility and flammability of these solvents, the coating needs to be warmed to 50 ° C during the dip coating process and baked at 110 ° C after dip coating. This kind of craft should have strict defense
