The difference between sulfur-free paper and plain paper

The difference between sulfur-free paper and plain paper is that we often use paper in our lives, especially every day at school. Paper is a thin sheet made of plant fibers. Paper has a wide range of uses, and it is used in different fields. There are differences, such as industrial paper and household paper. Industrial paper, such as printing paper, sulfur-free paper, oil-absorbing paper, dust-free printing paper, kraft paper, dust-proof paper, etc., household paper, such as books, napkins, newspapers, toilet paper, etc. There is still a difference between industrial sulfur-free paper and our commonly used plain paper.
Sulfur-free paper is used by circuit board manufacturers to make special pad paper for PCB silver making process to avoid chemical reaction between silver and sulfur in the air. Its role is to chemically sink silver to avoid chemical reactions between silver in the air and sulfur or even yellow. It does not contain sulfur, which can avoid the adverse effects caused by the reaction between sulfur and silver.

At the same time, the sulfur-free paper also avoids the chemical reaction between the silver in the electroplated product and the sulfur in the air, which causes the product to turn yellow. Therefore, after the product is made, please pack the product with sulfur-free paper as soon as possible, wear sulfur-free gloves when touching the product, and do not touch the plated surface.
Sulfur-free paper can avoid the chemical reaction between the silver in the electroplating product and the sulfur in the air. Plain paper is not suitable for electroplating paper because of too many impurities.
When sulfur-free paper is used in the PCB circuit board industry, it can effectively inhibit the chemical reaction between the silver in the PCB circuit board and the sulfur in the air.
Sulfur-free paper is dust-proof and will not drop debris. Plating industry surface debris will affect the plating effect. If there are impurities in the PCB line, it may affect the connection.
Plain paper is mainly made of plant fibers, such as wood and turf. In addition to plant fibers, the raw material of sulfur-free paper is also equipped with non-plant fibers, such as synthetic fibers, carbon fibers and metal fibers, to eliminate sulfur, chlorine, lead, cadmium, mercury, hexavalent chromium, polybrominated paper biphenyl and polybrominated diphenyl ethers. In order to make up for some shortcomings of the base paper, it is helpful to improve the quality of the base paper and achieve the purpose of optimizing the combination. Sulfuric acid paper wholesale also need attention.
