Environmental protection of sulfur-free paper

Sulfur-free paper is an environmentally friendly paper that can be recycled. In the development of paper industry, the role of sulfur-free paper has been highlighted. Sulfur-free paper is widely used in the silver plating process of printed circuit boards to play the role of silver lining. Sulfur-free paper is also relatively environmentally friendly paper, which can be recycled and is a typical environmentally friendly sulfur-free paper.

Sulfur-free paper is suitable for storage in a dry and clean warehouse at 18 ℃ ~ 25 ℃. Keep it flat, avoid direct sunlight, stay away from fire and water sources, pay attention to prevent high temperature, pay attention to moisture, and avoid contact with liquids (especially acid and alkali). Shelf life of one year. The same nature of sulfur-free paper and other ordinary paper is afraid of fire and water, so it is necessary to store sulfur-free paper in strict accordance with the requirements.
As a kind of recyclable environmentally friendly paper, sulfur-free paper is also becoming a shopping bag in people's hands. This shopping bag can be recycled without pollution, the production process is simple, and it can be recycled and reused, which greatly reduces the production cost. People's daily shopping choice.
Sulfur-free paper has brought great convenience to people's industrial use and life. The emergence of sulfur-free paper has reduced the production cost of the factory, and has also contributed to our environmental protection cause, allowing us to stay away from unhygienic plastic packaging.
Sulfur-free paper is a special pad paper used by circuit board manufacturers for PCB silver conversion process to avoid chemical reaction between silver and sulfur in the air. Its role is to chemically deposit silver, thus avoiding the chemical reaction between silver and sulfur in the air, resulting in yellowing. Does not contain sulfur, can avoid the disadvantages of sulfur and silver reaction.
At the same time, sulfur-free paper also prevents the silver in the electroplating product from chemically reacting with the sulfur in the air, causing the product to turn yellow. Therefore, after the product is completed, it should be packaged with sulfur-free paper as soon as possible, and wear sulfur-free gloves when contacting the product, and do not touch the plated surface. sulfuric acid paper wholesale, dust-free printing paper also need attention.
