The history of the coated abrasives industry dates back centuries. As early as the 13th century, our ancestors used natural resins to adhere crushed seashells onto sheepskin for grinding purposes. In the 16th century, Europeans started making abrasive tools by attaching natural abrasives to animal hides. By the 18th century, "Grinding paper" was already being sold in Paris. In 1808, Europeans began producing coated abrasives by mixing finely ground pumice with molten varnish and applying it to paper using brushes. In 1831, an Englishman named Lothrop invented sandpaper by combining animal glue, emery, or sand, and glass on a cloth substrate. In 1844, France introduced machines for manufacturing sandpaper, and soon after, Germany, Japan, the United States, and other countries established sandpaper factories.


The Development of Coated Abrasives:


Throughout the 20th century, with advancements in mechanical engineering, the chemical industry, and electrification, the coated abrasives industry witnessed significant progress. In 1904, the first suspended dry grinding production line for sandpaper was introduced. In 1951, successful research on electrostatic sand planting reduced the curing time from around 10 hours to just a few seconds, significantly improving the quality of the products.


In 1953, the development of sanding belts began, and in 1955, they were introduced into the aerospace industry. Due to continuous technological advancements, the coated abrasives industry has experienced rapid growth in terms of product variety, quality, production output, and application range. Currently, there are over 40,000 different types and specifications of coated abrasives worldwide, utilizing more than 750 different raw materials. The production volume has been steadily increasing. In industrially developed countries, the value of coated abrasives production exceeds that of any other type of abrasive, accounting for 40% of the total abrasive production value (approaching 50% in countries like Germany).

 


In China, the development of coated abrasives started after the liberation period. Before that, there was only one small factory in Shanghai producing hand-operated wooden sandpaper, with an annual output of 3000m2. Today, there are over 100 coated abrasives factories in China, including major players like Zhengzhou Baige Group and Shanghai Grinding Wheel Factory. The introduction of sanding belt production lines from Germany has brought significant economic and social benefits to the industry.


The development of coated abrasives has a long and rich history, with its origins dating back centuries. Over time, advancements in technology, industry, and manufacturing processes have led to remarkable progress in the coated abrasives industry. Today, coated abrasives offer a vast range of products, utilizing numerous raw materials, and are widely used in various applications worldwide. The industry continues to evolve, driving innovation, improving quality, and meeting the growing demands of modern grinding processes.
