Where do I need to put on record for selling rock wool in Xuzhou?

No need to file.

Rock wool originated in Hawaii. After the first volcanic eruption on the island of Hawaii, residents on the island discovered thick melted soft rock, which is the first known rock wool fiber.

The process of making rock wool actually simulates the natural process of volcanic eruption in Hawaii. Rock wool products are mainly made of high-quality basalt and dolomite, which are melted at a high temperature above 1450℃ and then spun into fibers at a high speed by an internationally advanced four-axis centrifuge. At the same time, a certain amount of adhesive, dustproof oil and waterproof agent are sprayed, collected by cotton collector, and cut by pendulum method and three-dimensional method after curing to form different specifications and sizes.
