A few days ago, the reporter learned from the First Financial China Furniture Forum: The black-hearted sponge that appears quietly on the market today actually reduces the sponge and stone powder by “cutting the work.†The cheap stone powder strengthens the hardness and density of the sponge, but it It greatly shortens the service life of the sponge as a whole and affects the safety of the human body. In the recent national quality inspection of soft furniture, it was found that the products produced by some small workshops did not meet the national standards in terms of materials, moisture content, and sponge density. In particular, the gaskets used inferior sponges and even added Stone powder. According to Qian Hongxiang, an expert of the China Foam Plastics Committee, the addition of stone powder can greatly reduce the production cost of the sponge, and it can also strengthen the hardness and density of the sponge; however, the adulteration of the sponge makes the sponge elastic, flexible, tensile strength, tear Crack strength and compression performance also deteriorate. Experts pointed out that pure sponge has good pressure resistance, high tensile strength, good fatigue resistance and longer service life. Since the true and false sponge light is difficult to distinguish from the naked eye, experts call on manufacturers to use pure sponge consciously. Consumers can also ask the manufacturer to express the "pure sponge" mark when purchasing soft furniture.
