Don't plug the toilet, not easy to break, how to make a good toilet paper?

You will probably use very much toilet paper in your lifetime: 49 rolls/year, 3,787.7 rolls/year. So much! ? As we all know, all toilet paper must indicate the type of raw material. So how are they made? To put it simply, turn these tall, hard trees into white, soft toilet paper in your hands in just four steps: Make pulp: Make pulp from trees; Pulp processing: further processing of pulp; Spray into paper: spray drying into paper; Cut roll packaging: Roll into the toilet paper we use. It sounds simple, but in every detail, there's something we don't know.

Although there are so many types of toilet paper, in fact, pulp raw materials, is the main factor that determines the health and price, the state stipulates that all toilet paper and paper towels must be written on the packaging of raw materials, to this end, Baoding Hozhong Hygienic Products editors for you to list four raw materials used in toilet paper: non-wood pulp, first use and recycling materials and wood pulp. With this classification, you will be able to understand the name of the raw materials on the package in seconds, and will not be fooled by merchants. Among them, the first use refers to the original non-wood pulp and the original wood pulp, and the recycled material refers to the recycled pulp. The raw material of the original pulp toilet paper is plant, that is, the use of new natural plants as raw materials, pay attention to these three keywords: all, new and natural plants. Recycled pulp, as the name suggests, is produced from recycled materials. What recycled materials? The author consulted the national standards, recycled pulp can only use recycled paper and printed matter, usually some waste books, newspapers and printed white paper edges as raw materials, can not use waste household paper, medical paper and packaging paper and so on. Recycled pulp toilet paper is usually cheaper, but the quality is low, shake a bathing suit off ash hair, you almost never see such products in the supermarket, because recycled pulp raw materials are easy to mix fluorescent substances and heavy metals, privacy, it is not recommended to use this toilet paper to wipe the face and mouth. In addition to the two concepts of raw and recycled, toilet paper raw materials are also divided into wood pulp and bamboo pulp, and in recent years, there are wheat straw, reed and bagasse and other raw materials made of pulp. In addition to these clear raw materials, some businesses reuse the marketing concept of chicken thief to mislead consumers, such as: pure wood pulp, sounds quite advanced, but the original wood pulp plus recycled pulp, can also be said to be pure wood pulp. There is pure virgin pulp, it may contain wood pulp and non-wood pulp, if you do not understand these concepts, please look for the original wood pulp on the right. Now that we're done with the categories.

Let's talk about something you might not know. Toilet paper may be a Nordic style product in your home, the manufacture of high-quality softwood pulp is mainly from the Nordic countries and Canada, the United States, Chile, Russia and other countries. Due to China's environmental protection policy strictly limits the cutting of trees and paper, so the manufacture of high-quality raw wood pulp needs a large number of imports, the total amount of imports between 25 million to 30 million tons, almost half of the global trade, the special transport of this pulp giant ship, a ship that is more than 200 meters long, need more than 700 ships to complete the transport. Although the word pulp may seem wet, like a liquid, as a global commodity, it is actually dry, which needs to be dried and dehydrated to turn it into a fiber like a blanket, avoiding the shipping industry as nature's porters.

The raw pulp is directly made into paper, the experience of wiping the butt is similar to sandpaper, in order to make the Toilet paper more soft, the pulp must go through a processing link called pulping, in this process, it will change the shape of the fiber, control the ratio of long and short fibers, and give us a warm body feeling. In the beating process, the factory will use a pulper, a pulper and other machines to complete this process, adding water to the wood pulp to break the pulp, and then removing sand, grinding, and dredging. After this series of processes, the pulp fiber will be further cut off, and at the same time, the thick and straight fiber will become like a broom. In this link, the pulp passes through a pressurized nozzle. Evenly sprayed on the mesh surface (completed in the slurry box), then extrusion dehydration, and then into the dryer, further high temperature drying (press dehydration dryness ≈50%), while high temperature also has the effect of sterilization. When the dehydration dryness is ≈93%, it is necessary to carry out a very important process in the production of toilet paper: wrinkling. The paper allowance slides on the dryer to the edge of the scraper, where the paper will be scratched into small wrinkles, like the wrinkles that age has scratched into your face. Wrinkles are essential to toilet paper, and the scraper can break the bond between the fibers, making the fibers even looser. After the paper wrinkles, the longitudinal elongation can be increased by eight times, the thickness of the paper increases by three times, and the stiffness is reduced by 38%, which means that the paper becomes more elastic, thicker, more absorbent, and more soft. This link has a great impact on the final quality of the toilet paper. If the strength and stiffness of the scraper are not enough, the paper will often clamp. Small wrinkles will become big wrinkles, in general, the Angle of the scraper and the dryer is not 18-30 degrees, cold and hard metal, through precision Angle calculation, can make the paper produce fine and even wrinkles, a little change will affect the final user experience. The paper that comes out of this link will be rolled into jumbo roll paper, some weighing hundreds of kilogram, some weighing several tons. A roll of 200 kilograms of jumbo-roll paper is enough for a family of three for 10 years. Single-layer semi-finished paper is too thin to give us enough security, so manufacturers will put several large rolls of paper together on the machine to roll into multiple layers of finished toilet paper. In general, three and four layers of toilet paper can allow you to save paper without letting your fingers touch something you don't want to touch. In order to be convenient to tear when using, you need to press a dotted line, core and no core is not a sign of toilet paper grade, but suitable for different conditions of use, no matter which kind, you need to cut into small rolls, and then packaged and sold, after this long journey, a tree, a pine that has experienced the Scandinavian snow, Finally came across a fast-growing eucalyptus that had been bathed in the South American sun. In the trial of water and fire, they become completely one, white, light and soft, they embrace each other, together to the glorious end.

The above is the knowledge about toilet paper elaborated by the author. At the end of this article, the author also reminds you of three points for attention: First, the standard of bacterial colony toilet paper is lower than paper towels, so the national standard stipulates that toilet paper must be marked on the package with the words for toilet use, and it is really unsanitary to wipe the mouth with toilet paper. The second is that the amount of powder dropped by toilet paper shall not exceed 0.5% of its own weight, and the second paper towel will not drop powder. Therefore, allergic rhinitis patients, do not use toilet paper to wipe the nose, may wipe more serious. Third, paper towels do not add water-soluble fibers like toilet paper, which leads to it easily blocking the toilet, so if you temporarily use paper towels instead of toilet paper, it is best to still put it in the paper basket.

This article is basically about these. If you also have some questions about the understanding of toilet paper, you can contact us, the author in this professional to answer your questions, thank you.
