On the 9th, the Guangdong Provincial Bureau of Quality and Technical Supervision notified the regular supervision and inspection of the quality of 20 kinds of products such as packaging machinery in Guangdong Province in 2014. Among them, the results of regular supervision and inspection of the quality of fixed/removable/embedded lamps show that the rate of unqualified products is 11.6. This test examined 267 batches of fixed/removable/embedded lighting products produced by 202 enterprises in 9 cities (regions) including Guangzhou, Shenzhen, Zhuhai, Foshan, Huizhou, Dongguan, Zhongshan, Jiangmen and Shunde. The inspection basis is GB7000.1-2007 "Lamps Part 1: General Requirements and Tests", GB7000.201-2008 "Lamps Part 2-1: Special Requirements Fixed General Lamps", GB7000.202-2008 "Lamps No. 2 -Part 2: Particular requirements for recessed luminaires, GB 7000.204-2008 "Lamps Part 2-4: Special requirements for portable general luminaires", GB 17743-2007 "Electrical lighting and similar equipment for radio disturbance characteristics and limits Measurement method", GB17625.1-2012 "Electromagnetic compatibility limit harmonic current emission limit (device phase input current 16A)" and the current effective enterprise standards and product express quality requirements for the mark, structure, external wiring And internal wiring, grounding regulations, protection against electric shock, insulation resistance and electrical strength, creepage distance and clearance, thermal test and durability test, heat/fire resistance and tracking resistance, harmonic current, insertion loss (disturbance voltage) 11 items Tested. The inspection found that 31 batches of products were unqualified, including Asno floor lamp, Wanda Feng wall lamp, Hengguang embedded LED lamp (LED ceiling lamp), Kamida LED lamp, dragon LED fixed lamp, Masden Shifting incandescent lamps (table lamps), Huangjia lighting fixed incandescent lamps and other brand products. Non-conforming items relate to structure, external wiring and internal wiring, grounding regulations, protection against electric shock, heat/fire resistance and tracking resistance, harmonic current, insertion loss (disturbance voltage), etc. In accordance with the relevant laws and regulations, the Guangdong Provincial Bureau of Quality and Technical Supervision has instructed the relevant departments to deal with the unqualified products and their production enterprises found in this regular supervision and inspection according to law.
ZHENGDA Curing Agent
ZHENGDA Curing Agent is an efficient concrete curing agent, which is widely used in construction, road, bridge and other engineering fields. It is made of high-quality raw materials and has the characteristics of efficient curing, strong durability and convenient construction.
The main component of the curing agent is polyamide ester resin, which can quickly react with the cement in the concrete to form a high-strength chemical bond, making the concrete more robust and durable. In the construction process, only need to apply the curing agent to the concrete surface, and then mechanical polishing or grinding, you can achieve the ideal effect.
ZHENGDA curing agent can not only improve the strength and durability of concrete, but also effectively prevent the phenomenon of sand formation and powder drop on the surface of concrete. At the same time, it can also play a waterproof, dustproof, oil and other functions, making the concrete surface easy to clean and maintain.
The curing agent is suitable for all types of concrete surfaces, including newly poured concrete, old concrete restoration, industrial floors, etc. Not only that, it can also be used indoors and outdoors, adapting to a variety of environmental and climatic conditions.
In short, ZHENGDA curing agent is an efficient and reliable concrete curing agent, which has been widely used in construction, roads, Bridges and other engineering fields, and has become the preferred product for concrete surface treatment.
