Special paper is the paper with special properties and uses, such as insulating paper, waterproof paper, fireproof paper and so on. Special paper industry are inseparable with chemical industry,textile, building materials and other industries. There are no strict boundaries between non-woven industry and paper and wallpaper industry. In fact, part of the process used in the non-woven fabric industry is also the paper-making process. It is necessary for the special paper industry to combine its technology with the technology of related industries.
The development of high-speed trains requires two types of special paper, one is insulation paper and the other is Nomex honeycomb. Insulation boards are now very expensive. With the domestication of high-speed trains, the market for insulating paper will be very large. High-speed trains running at speeds of up to 300 kilometers per hour require a large amount of Nomex honeycomb. Because Nomex honeycomb can help high-speed trains reduce energy consumption and noise.
Nomex honeycomb is also used to make aircraft and is used in very large quantities. American aircraft carriers also use Nomex honeycomb, and an aircraft carrier need to use a ton of Nomex honeycomb. As the use increases, the Nomex honeycomb market will grow larger and larger.
At present, our country uses inorganic fiber to develop the paper and paperboard with performances of fire resistance and thermal insulation. The principle of using inorganic fiber to make paperboard can be combined with other materials to produce base boards, while organic fibers PP and PE can be used for special paper. This research also promoted the further development and progress of insulation paper industry. But it is not enough to depends totally on a small team, we must combine with disciplines on materials and chemical, taking advantage of multiple disciplines, and cooperate closely. In applied research, according to the needs of the factory, we need to adopt the working style of "walking on two legs", doing advanced research on the one hand, and on the other hand, doing some short term rapid research projects according to the pressing needs of the factory.
The most important aspect of the development of special paper is that the product or industry can be used for other materials, such as paper replacing plastic. We have done a lot of work in this area. Let’s imagine to extend the industrial chain from paper and cardboard to high-end physical materials to produce paper ultrafiltration membrane and permeable membrane; to produce paper yarn for textile industry; to use paper materials to process into fabrics similar to cloth structures to replace cloth. If we can do these, special paper industry has a great space for development.
