What are the types and models of cleanroom paper?
Dust-free paper, also called dry-laid nonwovens, is a type of dry-laid nonwovens. Like ordinary paper, dust-free paper is also processed from wood pulp. However, the dust-free paper adopts the air-laid technology. After forming, it is strictly reinforced, and finally the edges are sealed, which can strictly control the dust-removing behavior of the dust-free paper. The dust-free paper has high elasticity, softness, hand feeling, excellent drape, extremely high water absorption and good water retention performance.
Dust-free wiping paper, smooth surface, delicate touch, not easy to scratch the surface of the object; good elasticity, not easy to tear, not easy to tear; it is widely used in semiconductor production lines, microelectronics production, LCD display, circuit board production, PCB production Products, screen printing, laboratory, clean room production line, mechanical maintenance, automobile maintenance and other fields.
Types of clean paper: The current clean paper industry is developing vigorously. There are also different classifications of clean paper for different usage scenarios. On the market, clean paper is roughly divided into 0609 wood pulp polyester composite spunlace cloth. Dust paper, polyester and viscose composite spunlace dust-free paper, meltblown non-woven fabric and microfiber non-woven fabric.
1.0609 Wood pulp polyester composite spunlace cloth clean paper, made of 50% wood pulp + 50% polyester, has the characteristics of less chip removal, large absorption capacity, strong decontamination ability, etc. It is usually used for precision metal surface wiping, SMT wiping Wait.
2. Polyester and viscose composite spunlace clean paper is made of viscose and polyester. The surface of the product is soft and the porous structure gives the product good dust removal ability, which is suitable for wiping precision machinery parts and so on.
3. Melt-blown non-woven fabric, made of polypropylene fiber, has strong absorption function and high cleanliness, is a good material for removing organic solvents, suitable for wiping precision parts, removing silk screen ink, etc.
4. Microfiber non-woven fabric is also made of polypropylene fiber. It is the same as 0609 dust-free paper. It has the characteristics of less chip removal, large absorption capacity and strong decontamination ability. It is also suitable for wiping precision parts, removing silk screen ink, etc. .
5. In addition to sheet packs, dust-free paper also has paper roll specifications, which are suitable for wiping machines in workshops, which can keep the cleanliness of the equipment at all times and ensure that the products are as free from environmental pollution as possible.
Dust-free paper classification 2: Dust-free paper is mainly divided into heat-bonded dust-free paper, glued dust-free paper, and comprehensive dust-free paper. Heat-sealed clean paper is formed by mixing fluff pulp and hot-melt fibers, and the fibers are mainly bonded by the melting of hot-melt fibers; glued clean paper is made of fluff pulp fibers air-laid and bonded with latex; comprehensive clean paper is Between the two, there are both hot-melt fiber bonding and a small amount of latex bonding. Compared with ordinary glued clean paper, heat-bonded clean paper has more excellent properties in bulk, wet and dry tensile strength, softness and liquid absorption.
