Jewelry Recycling

Gold as a broad physical asset investment, the gold pawn and recycling is a high-return, high-yield, but also high-risk industry. In actual investment transactions, the phenomenon of insufficient purity or adulteration of gold and silver jewelry (such as tungsten, rhenium and coating-gold) often occurs. In order to ensure the fineness of recycle gold and avoid risks, choosing traditional time-consuming destructive testing or rushing to third-party testing institution at high costs every day no longer meet customer needs and cost control.

RoHS

On June 4, 2015, the Official Journal of the European Union (OJ) issued RoHS2.0 Amendment Directive (EU) 2015/863, which consists of the original six controlled substances: lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr VI), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE); added 4 item phthalates: DEHP, BBP, DBP, DIBP, enforced since July 22, 2019, so far RoHS2 .0 controlled substances reach 10 items.

Coating Thickness

How to accurately, quickly and non-destructively detect the coating thickness of materials is a challenge. If the coating is too thin, the final material may fail prematurely in actual use due to corrosion, wear or poor electrical contact of electronic components. Too thick coating will affect the assembling method of complex materials and increase the cost of plating (such as engine parts). For jewelry surface coatings, the correct thickness is essential to ensure the aesthetics of the finished product; if the coating thickness is wrong, the entire assembly will need to be reworked or scrapped.

Silicone Oil Coating

It is critical to obtain accurate thickness and quality of silicone coatings on paper, film and release film, if the coating is too thin, the layer may not detach adequately and the product will be unusable. If the coating is too thick,the production costs will become too high. If adhesive paper or film is used for the PCB, any residual silicone on the adhesive layer can adversely affect performance. So the quality of the silicone coating must be carefully controlled.

Manufacturers can save costs and increase profits by using CFAN analyzer to precisely control the amount of coating applied to product specifications.

Stainless Steel

Aluminum alloy refers to an alloy based on aluminum with a certain amount of other alloying elements added, and is one of the light metal materials. Aluminum alloys are the most widely used non-ferrous metal structural materials in the industry. For the determination of alloying elements such as Cu, Mn and Fe in aluminum alloys, chemical methods and photoelectric direct-reading spectroscopy are generally used. The chemical analysis time is long and the operation is complicated. Photoelectric direct reading spectroscopy has strict requirements and restrictions on the shape of the sample.

Ternary Catalyst

The exhaust gas purification device of the automobile, referred to as the ternary catalyst, its main function is to oxidize and reduce the carbon monoxide, hydrocarbons and nitrogen oxides in the automobile exhaust gas to generate carbon dioxide, nitrogen and water that are harmless to the atmosphere, thereby achieve purification results. Ternary catalytic converters mainly contain three precious metals: platinum (Pt), palladium (Pd), and rhodium (Rh). Generally, the ternary catalyst equipped with the original car contains about 1-3g of precious metals, and about 1.5g of platinum can be extracted per kilogram of catalyst powder.
