But on the market a lot of nano-sponge wear too much, easy to crack, easy to drop slag, easy to wear, so how should we identify and select high-density nano-sponge it? 1. Smell: the General nano-sponge Smell will have a faint, very unpleasant smell, Xiamen Sihang Compression nano-sponge is almost smell of the flavor. 2. Pinch: Xiamen Sihang compression nano-sponge flexibility, elasticity is very good, hand pinch, squeeze water are not easy to break, broken, you can squeeze pinch; but if the general nano-cleaning sponge can not pinch, with a little bit of force, it would break, and you could hear the tiny sound of the sponge breaking. 3. Uses: Xiamen Sihang compression nano-sponge density is higher, the number of nano-capillary per unit area more, cleaner, use wear-resistant, more durable, almost no slag; Ordinary nano-sponge cleaning effect is also good, but the dross is very serious, easy to break, not used. Of course, for the compressed nano-sponge, but also the quality of the contrast. Xiamen Sihang high-quality density nano-sponge more flexible foot, sponge rebound feel strong. Pressing the side edge of the nano-sponge is uniform and flexible, pressing the middle density of the nano-sponge is uniform. The reason is very simple, non-standard high-density nano-sponge can only be compressed on both sides of the sponge, and the middle part can not be compressed effectively. When used in this way, it is easy to delaminate from the middle, and the sponge is not durable as the ordinary nano-sponge after surface abrasion, and is easy to be damaged and dregs.But on the market a lot of nano-sponge wear too much, easy to crack, easy to drop slag, easy to wear, so how should we identify and select high-density nano-sponge it? 1.
