Brief introduction of environmental protection technology of metal buttons
People often refer to a non-environmental product as an environmentally friendly product. At present, various countries have a special system for “environmental protectionâ€. Environmental products can be seen everywhere in our lives. Many companies pay attention to putting up their own products when advertising. It is environmental protection and low-carbon. With the improvement of people's awareness of environmental protection, environmental protection products have become more and more popular.
Although the metal buttons seem to be small, they are just a small ornament in the clothing. However, many of our export garments are due to the environmental protection of small buttons that lead to the return of the product. This really should be the sentence: “A rat smashed A pot of porridge." In order to comply with the world trend and protect the world's ecological environment, environmental-friendly metal buttons should arouse our attention. Here are some characteristics of the environmental protection of metal buttons.
Button environmental protection requirements: The environmental protection of metal buttons mainly refers to the requirement for flawless plating, surface treatment such as oil injection, and the absence of flaws. For environmental protection buttons, electroplating must be based on non-barium electroplating, and according to the requirements of garment production and processing, it is sometimes necessary to further process after electroplating: such as trusses, anti-acid trusses, high temperature trusses, etc., these are not much with environmental protection Relationships only play a role in protection (for example, preventing discoloration, preventing rust, etc.). According to customer requirements, we may also spray, grease, dip, and insert diamonds on the surface of the electroplated buttons. Remember that the materials used in these processes must be made of environmentally friendly materials. The current method of detecting environmental protection buttons is through drug testing (similar to the method of pH test paper, using Amoniya potions for testing), and QCs of general production plants can perform tests on their behalf. Common buttons in the rolling color, green bronze, white zinc, red bronze and other colors are environmentally friendly colors. Some garment factories require manufacturers to send products to testing agencies for testing and issue inspection certificates. Such as SGS test report. Needle detector requirements: The needle detector refers to the use of electromagnetic principles, the product of the unit area of ​​iron (nickel) detection. If electroplating is not flawless, the needle must not be crossed. High-precision copper products, nickel-free surface treatment, can check the needle. Because the copper material in the classification, there are 62/65/68 (68 copper on the market, actually 65 high-grade copper), and sometimes even the manufacturer uses some copper material for waste recycling, which contains high iron content. It is not possible to pass the needle.
In summary, the button product requirements for environmental protection means that the finished product does not contain azo, lead-free or nickel-free products. After the needle is detected, the product can pass the needle detector. The prevailing view is that environmentally friendly products may not be able to pass the inspection needles, but products that pass the inspection pins must be environmentally friendly. Of course, as an environmentally friendly metal button, the material itself must not be ignored. If we use buttons containing excessive amounts of iron to make buttons, the material will not be able to be electroplated without flaws, so it is impossible to make environmentally friendly metal buttons.
