How to distinguish between M-3 dust-free paper and lens cleaning paper
1. Comparison of the appearance of M-3 dust-free paper and lens cleaning paper (M-3 dust-free paper on the left, 0, 2725 g / 121 cm2; right lens cleaning paper, 0, 1277 g / 121 cm2)
2. M-3 dust-free paper has unique physical properties, manifested as high elasticity, softness, hand feel, excellent drape, high water absorption and good water retention performance, and is widely used in health care products, special medical Supplies, industrial cleaning supplies and other fields.
Although M-3 dust-free paper is called paper, it is essentially a non-woven fabric. Two main characteristics of M-3 dustless paper: one is wood pulp fiber as the raw material; the other is air-laid technology. The production process of non-woven fabrics is mainly two processes of web forming and reinforcement. Dry papermaking nonwovens are produced using two methods, chemical bonding and thermal bonding. Dust rate paper, good strength.
4. Tissue paper is a thin paper used for packing and wiping precision instruments. Suitable for wiping microscope, camera lens, TV screen, medical equipment, etc. Long fiber hemp, pure cotton or chemical wood pulp is used for papermaking, no filler is added during papermaking, and no calendering is required. The paper is uniform, white, light, thin, soft, no lint, no crumbs; high surface strength and softness. Some products contain surface-active substances such as silicones to improve the detergency and wiping effect. It also has excellent self-dissipation performance, which can dissipate the current conductance. The basis weight is generally below 20g / m2.
