Mr. Zhong is the purchasing manager of an industrial vacuum cleaner company. Some time ago, he called Aoqun Xiaoliu, saying that their company's industrial vacuum cleaners need to use a large number of vacuum brush heads, but the vacuum brush head requires anti-static function, asking Aoqun whether to produce vacuum brush head products.

Xiao Liu said to Mr. Zhong: "Our Aoqun company has specialized in the production of vacuum brush heads for more than 20 years, with an anti-static level of 10⁴-1012Ω. The products are available in the shape of arch bridges, oval boxes, square boxes, etc. Choice; product filament is tidy, tight, and tensile strength ≥6KG. "3 days later, according to the requirements of drawings provided by Mr. Zhong, Xiao Liu delivered a model for him to test.

Ten days later, Mr. Zhong gave feedback to Xiao Liu: "The vacuum brush head sample provided by your company has been tested by our technical department, and the anti-static effect is good, which meets the requirements of our products. Aoqun is really good. "
