Background technology
Metal zip fastener belongs to one kind of slide fastener, refers to the slide fastener that the miaow tooth of slide fastener is made by copper material or aluminium material, compares
More firm for nylon zipper and injection molding zipper, cost is also higher, is used on jeans, fur clothing overcoat and high-grade case and bag.
Different colors are presented after the miaow tooth of metal zip fastener is electroplated, common plating tooth color has blue or green bronze, red bronze, black bronze, electricity
Copper-nickel alloy, gold copper, dark fund copper etc..
Metal zip fastener is on dress ornament during use, and its coating and material can occur because of the erosion of surrounding air or environment
Get rusty, aoxidize, bubbling, the phenomenons such as speckle occur, so as to influence slide fastener outward appearance and performance.Therefore, metal zip fastener is in application
It is both needed to before dress ornament by detection, detection environmental simulation slide fastener miaow tooth is aoxidized in application, changed colour, the process such as get rusty, and is passed through
Testing result, from Sources controlling slide fastener quality problems.
GB/T 10125-2012 being used the detection of current metal zip fastener more《Artificial atmosphere corrosion test salt spray test》With
GB/T 19746-2005《The corrosion salting liquid week leaching experiment of metal and alloy》Standard detecting method is detected.Both inspections
Survey method is directed to all metal class products and formulated, therefore, and the specific aim that it is detected for metal zip fastener is weaker, detection
Condition and evaluation of result method do not reflect the corrosion process of metal zip fastener when in use well.As clothes slide fastener occurs
Oxidation is general to occur oxidation reaction during ready-made clothes warehouse and storage, and reaction medium is air, and both the above national standard is detected
Method reaction medium is salt fog or salting liquid；And for example many metal zip fasteners arrange in pairs or groups corium fur clothing and cashmere overcoat is used, this
Two kinds of materials carry out high-temperature dyeing using acid dyes, and staining solution pH is between 3.5-4.0, and metal zip fastener is with above-mentioned two
It is many to be tested using weakly acidic pH environment when planting national standard method detection.Analysis is compared more than, existing metal product is anticorrosive
Examination criteria, because test environment, tested media etc. can not simulate the environment that actual dress ornament storage is aoxidized, therefore can not be fine
Reaction slide fastener discoloration corrosion condition.At present, also not specifically designed for metal zip fastener coating and main material matter decay resistance
Detection method.In addition, both the above national standard detection method, used equipment is more complicated, and detection time is also longer, it is impossible to
Meet the requirement of the larger detection limit of dress ornament enterprise.
