Recycled paper is waste paper as raw material, which is broken, color-removed and then processed through high-tech methods and processed through various complicated processes. 80% of its raw materials are derived from recycled waste paper, and are therefore regarded as low-energy and light-polluting environmentally-friendly paper. Urban waste papers are various. After the manufacturers recycle them, they are divided into more than 60 categories. Different types of waste paper are used as raw materials to make different recycled photocopy papers and recycled wrapping papers. Generally can be divided into two categories: one is low-grade paper such as hanging-panel paper and toilet paper; the other is paper for magazines, copy paper, printing paper, postcards, and exercise books. At present, many countries have produced and used these two types of paper. Among them, the raw materials for the production of recycled copy paper are office waste papers, offset books, binding papers, and other types of urban waste paper that have relatively good original paper quality. The production process is subject to screening, dust removal, filtration, and purification. Processes, complex processes, high technology content. With the increase of people's awareness of environmental protection, recycled paper products will be more and more recognized and welcomed by people. Therefore, for paper manufacturers, the recycled paper market is promising.
Features
1. Neutral sizing of wood pulp can be stored for a long time, and it is not easy to turn yellow. All wood pulp paper can be recycled and reused 100%, so it has good environmental protection.
2. The use of copying base paper designed and manufactured for office use, is willing to have first-class performance, applicable to all kinds of office equipment.
3. The use of advanced paper surface treatment agents, inkjet printing leading the market similar products.
4. Good whiteness, soft color, long time reading and writing do not hurt the eyes.
5. The use of original manufacturing copy paper, paper quality is stable and reliable.
6. Each batch of copy paper must pass the professional copier high-speed test, the curl is small, the paper jam rate is extremely low, prolong the service life of the office equipment, and reduce the customer's comprehensive use cost.
7. All specifications are produced by automatic hob cutters to ensure excellent and stable cutting quality.
Misunderstanding of recycled paper
From the point of view of protecting the eyeballs, it is not the whiter the better the paper.
According to the department's inspection, the whiter the paper is, the stronger the light reflected by the fluorescent light is, and it is harmful to human vision. According to current international general standards, the whiteness of paper should not be higher than 84 degrees, and the whiteness of recycled paper is 84 to 86 degrees. The whiteness of raw wood pulp can reach 95 degrees to 105 degrees. At present, the most popular 83-degree recycled paper in the world, because the natural recycled paper can protect two balls - the earth and the eyeball.
Comparison of recycled paper and plain paper
Comparison of physical components
In 1995, they standardized recycled recycled paper as 25% recycled recycled fiber. This indicator was raised to 30% in 1999. A research unit in the United States has found that the paper strength decreases as the circulating fibers in the paper increase, but as the recycled fiber content exceeds 40, the paper strength increases. The concept of the average person thinks that the recycling process will cause damage to the fiber structure, and the loss of aqueous hemicellulose and the original strength agent will weaken the overall paper strength. Some people later refuted this statement and found that even if the paper undergoes six cycles, the change in fiber length is only very slight. This shows that there are other factors that cause this phenomenon.
Stone and Scallan's research report clearly stated that during the drying process, the surface area of ​​the pulp shrinks, reducing the partial binding capacity, which often occurs on chemical pulp. Conversely, during the cycle, the lignin in the mechanical pulp is gelatinized, the binding capacity and elasticity are enhanced, and the overall paper strength is increased.
Nowadays, many recycle paper manufacturers are constantly improving their production processes in order to bring the characteristics of recycled paper log fibers as close as possible. For example, additives are added to the chemical pulp or chemical treatment steps increase paper strength. However, since the ink and the contaminants in the paper are not completely removed, the brightness decreases as the amount of recycled fibers increases. In view of this, manufacturers will add some filler pigments or use different bleaching steps to increase brightness. The characteristics of recycled fiber are not always good, it can increase the opacity of paper, reduce the reflection and improve the quality of printed products.
