Recycling waste paper box function:
1, making recycled paper. This is the most widely used method of waste paper. It can be used not only to make recycled wrapping paper, but also to make recycled newsprint. This new process includes deinking, paper fiber purification, absorbing ink and impurities, and then making paper.
The specific process is as follows: according to the type of ink, choose deinking technology; Sending paper fiber and soap deinking agent into a deinking chamber consisting of two chambers, so that ink and impurities float to the surface with foam and are sucked away by a suction device; Concentrate the purified fiber pulp to 15%, heat it to make the paper fiber expand, and bleach it to make the recycled paper glossy; Finally, the high-concentration pulp is sent to paper-making equipment, which can be made into recycled paper with the same whiteness as new paper.
2. Make household appliances. In Singapore and other places, people use old newspapers, old books and periodicals and other waste paper raw materials, roll them into round slender sticks, wrap them with plastic paper, and manually weave carpets, cushions, bags, cat nests, door curtains, and even household appliances such as coffee tables and beds.
3. Processing into cattle and sheep feed.
Larry Berg, an animal nutritionist at Erie University in the United States, chopped old newspapers, added water and 2% hydrochloric acid, and then boiled for 2 hours, so that cellulose was decomposed and broken under the action of high temperature and acid, and then added to the feed of cattle and sheep, with the addition ratio of 20% ~ 40%.
Cattle farms and sheep farms in Britain, after a little treatment, cut waste paper into slender strips or knead it into small paper balls, and add a small amount of nutrients to feed cattle and sheep. Cattle and sheep can gain more weight by eating it 1/3 than by eating ordinary feed. Australian scientists crushed waste paper and mixed it with appropriate amount of linseed oil and honey to make granular feed for cattle and sheep, which can make them grow fat.
