The present application relates to the technical field of chemical detection, and particularly relates to a method for measuring the quality and content of plastic-wrapped gold products, comprising the following steps: S1, placing the plastic-wrapped gold product to be detected into DMF, heating to above 150 DEG C, heating for 10-15 min, taking out, tearing off the surface plastic wrapping, and obtaining a gold product containing gum; S2, performing oxidation cupellation treatment on the gold product containing gum to remove the surface gum part, and obtaining a treated gold product; S3, weighing the gold mass in the treated gold product, and detecting the gold content in the treated gold product by using fire assaying method. The present application can effectively remove various types of plastic wrapping materials and gum through the combined application of DMF preliminary treatment, composite sol agent pretreatment, multi-stage oxidation cupellation and fire assaying method, while maximizing the protection of the gold product itself, and significantly improving the efficiency and precision of the quality and content measurement of the plastic-wrapped gold product.

This invention relates to the field of profile surface treatment technology, specifically to a pre-treatment device and process for powder coating molding of outdoor product profiles that requires no cleaning. The device includes a treatment mechanism, an air collection mechanism, and a negative pressure mechanism. The treatment mechanism includes a through-type polishing machine. In this invention, during startup of the through-type polishing machine, its output end drives the chuck to rotate. Then, the crank, through a push-pull plate and a transmission plate, influences the piston rod to reciprocate up and down. Under the constraint of the air outlet, air inlet, and two one-way valves, the air cylinder continuously creates a negative pressure environment within air tanks one and two, preparing for the subsequent suction of impurities from the profile surface. When the polished profile approaches a photoelectric sensor, the sensor detects the incoming material and transmits the incoming material signal to an external PLC. The external PLC opens solenoid valves one and two, causing air tanks one and two to instantly suction away impurities from the profile surface through air pipes, thereby completing the cleaning purpose.
