Usage of sulfuric acid paper

Usage of sulfuric acid paper

Sulfuric paper is a translucent medium, specially used for engineering tracing and printing, the surface is not coated. Sulfuric acid paper in engineering, usually used to make base map, and used in the blueprint of the whole base map. Sometimes, it is also used as a title page in bookbinding to increase the effect, usually when the paper is blue. This paper is specially made of sulphuric acid. It is transparent, so it can be traced directly on the original file. Then you can make a blueprint. There are two benefits: draw a blueprint on sulfuric acid paper first, and then dry it to blue. If the drawing is wrong, the translucent sulfuric acid paper can also be cut and dried into a new blueprint.

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 in circuit board manufacturers to make special pad paper for PCB silver making process to avoid air

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. Sulfur-free paper and other ordinary paper the same nature, is afraid of fire afraid of water, so

Sulfur-free paper In order to prevent PCB oxidation, PCB has a silver precipitation process in this process, so PCB is also called immersion silver board. The silver plating process has become one of the important methods for the outer surface treatment of printed circuit boards. But there is a strong affinity between silver and sulfur. When encountering hydrogen sulfide gas or sulfide ions, it is easy to produce silver salts (Ag2S) that are difficult to dissolve in the air. Because the deposition rate of silver is very fast, a low-density silver precipitation layer is formed, which makes the copper under the silver layer easy to contact with air, so an increasingly thick silver plating layer is required to achieve oxidation resistance. This means that sulfur-free paper is produced.

How to better meet the market demand of sulfur-free paper industry

How to better meet the market demand of sulfur-free paper industry

2020-12-31

In recent years, with the rapid development of sulfur-free paper industry, many brands of sulfur-free paper have appeared in the market. With the late start of China's sulfur-free paper industry, compared with foreign brands, most of the sulfur-free paper brands are from abroad. At present, domestic sulfur-free paper brands are in the stage of seeking breakthroughs and development. However, in the case of fierce competition in the sulfur-free paper industry and great pressure on foreign brands, in the whole market environment, sulfur-free paper enterprises have begun to wake up: if they want to develop in the long run, they need to create a company that can be accepted and recognized by consumers. Establish a sulfur-free paper brand, establish a good brand reputation, based on market demand,
