Bathroom products and toilets have "fat"

Bathroom products and toilets have "fat" The reasons for the unqualified ceramic faucet sealing faucets were in the “salt spray test”. This supervision spot-checked 150 batches of products manufactured by 117 enterprises in 7 regions including Foshan, Jiangmen, Shunde, Guangzhou, Shenzhen, Dongguan and Zhuhai. 51 batches were qualified, and the rate of discovery of unqualified products was 34%. Quality Supervision Department's Pipe Thread Accuracy, Cold & Hot Water Marks, Thread Torque Test, Salt Spray Test, Adhesion Test, Valve Body Strength, Sealing Performance, Flow Rate, Cold and Heat Fatigue Test, etc. Tested. The inspection found that 51 batches of products were unqualified, involving pipe thread accuracy, cold and hot water signs, salt spray tests, valve body strength, flow, cold and hot fatigue tests and other items. The reporter noticed that in the list of unqualified products, most of the unqualified products were listed on the list due to unsatisfactory salt spray tests. According to insiders, the purpose of the salt spray test is to assess the salt spray corrosion resistance of the product or metal material, and the salt spray test result is the judgement of the product quality. It is a correct measure of the corrosion resistance of the product or metal against salt spray. The essential.

The discovery rate of unqualified products for sanitary ware products was 13.8%. This supervision spot-checked 80 batches of products produced by 52 companies in six regions including Foshan, Guangzhou, Zhongshan, Jiangmen, Zhuhai, and Shunde, and failed 11 batches of inspections. The product discovery rate was 13.8%. The spot checks on the appearance of sanitary products, chemical resistance to daily use, pollution resistance, Barcol hardness, resistance to load, impact resistance, hot water resistance, full water deformation, salt spray test, hydromassage, sealing, Remaining water, noise, returning devices, broken glass status, structure and assembly, structural strength of the house, electrical safety performance, steam generation and control functions, signs, operating instructions and other items were examined. The inspection found that 11 batches of products were unqualified, involving salt spray tests, Brinell hardness, signs and other items. Provincial Quality Supervision Bureau reminded consumers that when purchasing a shower room with steam function, it should be confirmed that the maximum temperature set by the controller is not greater than 60°C.

Toilet bowl, Mediterranean, Teppei, Ya Tao and other problems. The supervision conducted random inspections of 100 batches of products produced by 82 companies in eight regions including Foshan, Guangzhou, Shunde District, Zhongshan, Jiangmen, Dongguan, Qingyuan and Chaozhou. 13 batches of unqualified products were tested, and the rate of discovery of unqualified products was 13 %. Sampling inspection of 22 items of sanitary ceramic products such as water seal depth, water seal surface area, water absorption rate, water consumption, cleaning function, solid matter discharge function, sewage replacement function, water seal recovery function, and splash prevention . The inspection found that 13 batches of products were unqualified, involving water absorption, water consumption, cleaning function, solids discharge function, sewage replacement, water seal recovery function, splash prevention, matching requirements, water consumption identification, rinse noise, and Siphon function, safety water level technical requirements, installation relative position and other items. The toilet bowls of the Mediterranean, Teppanyaki, and Yatao all have products that have failed the water absorption project.

High Precision Optical Glass Window

Windows are optical glass with ground and polished faces that are relatively parallel.They are used to isolate two physical environments while allowing light to pass.Windows made of BK7 material have high transmission in the visible spectral region, do not scratch easily, do not degrade under normal operating environment and hence do not need any special precaution or treatment. Anti-Reflective Coating will provide higher transmission.
China Star Optics offers all types of windows made from different materials. Such as N-BK7, Fused silica, sapphire,CaF2, Silicon, Borofloat, high borosilicate glass and other optical glass supplied by Schott and Chinese CDGM are available upon request.

Windows at shape of round,quadrate, triangular or other polygonal are also available upon request.In addition, we provide a variety of single layer or multiplayer anti-reflecting coating,HR,PR coatings on Optical Windows.
