According to the reporter yesterday, the quality supervision and inspection results of 16 kinds of products such as paper products and paints released by the Provincial Quality Supervision Bureau show that electric blankets, student supplies, and energy saving. The quality of lamp products is more prominent. Among them, only 30% of the energy-saving lamps distributed by 31 companies in Lanzhou were qualified, and the pass rate of student supplies sold by 12 companies was 45. More than half of the student supplies contain whitening agents. It is understood that this time, a total of 60 batches of energy-saving lamp products from 31 distribution companies in Lanzhou City were sampled. The qualified rate of product quality inspection was 60. This spot check is based on the “Implementation Rules for Quality Supervision and Inspection of Self-ballasted Fluorescent Lamp Products in Gansu Province†and related standards, mainly for signs, interchangeability, prevention of electric shock, mechanical strength, heat resistance, fire and flame prevention, lamp power, power factor. 11 project indicators such as luminous flux, luminous efficacy and energy efficiency limit value were tested, and 24 batches of products had certain quality problems. A total of 20 batches of student supplies were sampled by 12 distribution companies in Lanzhou City. The type of products was booked. The pass rate of product sampling inspection was 45. According to the “Detailed Implementation Rules for Product Quality Supervision and Inspection of Student Supplies (this volume) in the fourth quarter of 2014 in Gansu Province†and related standards, mainly for the products of this book, arsenic, arsenic, cadmium, chromium, lead, mercury, brightness, whiteness, etc. 7 The project indicators were tested, and the brightness (whiteness) project indicators of 11 batches of products did not meet the standard requirements. According to the introduction of the provincial quality supervision staff, it was found through inspection that the company added a large amount of fluorescent whitening agent in the production process, which caused the paper of unqualified brightness to be abnormally white. Unqualified products may cause visual fatigue to consumers, especially students, and long-term exposure, vision will be adversely affected.
Zinc or Nickel Plating Production Line
Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.
Zinc-nickel alloy is an anti-corrosion coating with excellent corrosion resistance. At the same time, it has good mechanical properties and does not change the mechanical properties of the steel after plating. It has excellent brazing properties and is easy to weld under various conditions. The internal stress of the coating is small, which is comparable to that of the cadmium coating in the torsion-tension test. The plating solution has good dispersing ability and covering ability, high current efficiency, bright and smooth coating.
The zinc-nickel alloy plating bath has weak acid chloride type, sulfate type and alkaline zinc acid type.
The surface condition and processing requirements during electroplating, select the appropriate steps, and perform the necessary finishing processing on the surface of the part, so that the part has a smooth and clean surface, which is an important link in obtaining a high-quality coating.
