Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002]

renewable energy

The paper was invented by Chong Wang of Huhan, China in AD 105.

 Before that, people used animal skins, bones, bark, wood, bamboo, etc. in addition to stone, metal, and clay as materials for what they recorded. Among the materials used for these records, Papyrus Ancient Egyptians made a recording material using plants similar to wild reed papyrus on the Nile riverside. This method was devised around 2500 BC and the papyrus was more convenient than anything else at that time, so it was widely spread throughout Asia Minor from the Mediterranean coast until the 8th century when Chinese medicine was introduced to Europe, pulp? The etymology of the word 'paper' in European countries, including papyrus. However, the Egyptian papyrus was a very good technique for producing materials using plants. However, they did not develop such a superior technique, nor even developed the way of manufacturing paper, because there was a wealth of slave labor at that time, so that the material to be recorded could be saved in large quantities easily and inexpensively, It was a society.

 In China, paper can not be sure of its age, but silk was used together with the brush. In addition, there is a record that in the 10th year of BC, women used the thing made by increasing the residue of the pulp. The liver used in the passage is a bamboo, and the poison is a piece of wood that has been polished and recorded on the surface what is needed for the tree juice, and the pieces are connected with leather or a string.

Types of pulp include wood pulp, bamboo pulp, esparato pulp, linter pulp, infipulp.

In addition to wood, the pulp is cotton, hemp, flax, yellow hawthorn, japanese, manila hemp, mackerel mulberry, mulberry. Straw, espalato, bamboo, straw and the like can be used as pulp raw materials.

As described above, the pulp raw material is a fibrous material in plants, the length of the fiber is smooth, the quality is high, resistance to acid and alkali is large, and the change is small.

In the present invention, the sycamore tree (aka: bellflower tree), which is now popular as a tree-lined roadside tree, is rich in forests in the summer, grows well by several meters, creates a cool shade and purifies the city air by purifying carbon assimilation A giver is a very beneficial plant. In the fall, it is fallen down as fallen leaves.

The sycamore leaves (aka: vernacular) leaves are larger than the palms of human beings, and are very rich in fiber, soft and tough, and numerous porous.

So far, it has been known to use the litter as a manure or as a fuel.

In order to solve the above-mentioned problem, in order to use the tree litter of the tree as a papermaking raw material, the leaves are pulverized into sawdust-like form in a papermaking process in a papermaking raw material manufacturing process to produce papermaking raw papermaking wool, In order to use the raw material as raw material for processing paper, the process of producing pulp of recycled fiber is basically a process of sorting the paper.

Dissolving Process - Aging Process - Shipbuilding Process Deinking Process - Jeon Seon Process - Dehydration Process Seven Processes.

In the above process, it is preferable to use the litter of the present invention in the deinking process. To summarize, the deinking process starts with mixing and stirring the paper and water chemicals and raising the temperature. In this process, all the materials such as the printing ink contained in the paper are removed.

In the present invention, the decanted leaves produced by the present invention produced by the present invention can be used as a raw material for papermaking.

It is preferable to use sodium hydroxide (caustic soda) as the chemical agent while maintaining the water temperature in the deinking step. The ion concentration of the water is about PH13, and the water temperature is 80 to 90 DEG C. When the decolored composition is added to the water content of the defecation tank at about 70% and dehydrated for about 6 to 10 hours while stirring, Is injured.

When the floating material is removed and deinked, the used water is flowed and stirred to wash the alkaline solution adhered to the deciduous leaf composition, and then the raw material is flowed using an inclined screen, which is generally used to dehydrate the deciduous leaf composition, , And the fibers fall downward.

In order to increase the cross-linkability of the fallen leaves composition fiber, there is a method of increasing the fiber by punching and a method of increasing the cross-linking property by using several extrusion laura presses. In the present invention, After the paper material is extruded to make the paper material have a good spreading and crosslinking property, the raw paper material processed before the paper making process in the conventional paper making process is stored in the storage process, mixed with water and stirred slowly. The paper raw material is mixed with the litter paper raw material treated in the present invention in an amount of about 10% or a certain amount and mixed with the paper raw material so that the mixture can be added to the paper raw material.

The present invention can improve the functioning effect of recycled paper by using the recycled papermaking leaves by using the recycled papermaking process or the papermaking process equipment or by using it as an additive as a raw material for paper, What is useful is a feature of the present invention.

The present invention can be used to produce sawdust-shaped leaves in the form of sawdust by pulverizing the leaves as sawdust in the woodpowder process in the paper pulp raw material process in order to use the roadside leaves as a papermaking material. Since the deciduous sawdust is excellent in fiber quality, it is preferable to raise the temperature of the water and precipitate in a caustic soda solution for several hours in order to soften the fiber of the sawdust and increase the crosslinking property. The temperature of the water is raised, various chemical agents are put in, and the recycled paper is deinked. In the present invention, caustic soda is used to adjust the pH of the water to about pH 13 while maintaining the temperature of the water at about 80 ° C to 90 ° C by using the above process. About 70% of the volume of the water is added to the deciduous saw (sawdust) And the mixture was slowly stirred for about 10 hours. Then, the suspension of the fibers was removed, and the suspended solids were removed. The suspended solids were removed, the de-ionized water containing the caustic soda was drained, the water was added again and the caustic soda solution was washed. When the deciduous composition is flowed by using an inclined screen, the water escapes through the screen and the fibers fall down. Although it is preferable to perform the punching in order to increase the cross-linking property and to make the drossy dirt composition fibers fall apart, The present invention relates to an extrusion press having a plurality of used rollers, The lobe composition can be extrusion press.

Where punching process is used, punching method is widely used to produce Korean paper by punching Korean paper so that the fiber is spread, adhered and crosslinked. Also, in order to increase the efficiency of the work, the extruding roller is made into several steps so that the rollers can be used to increase the quality of the fiber, dirtiness and crosslinkability.

Any one of the present invention can be selected and used. The raw material for pouring or rolling the pliable composition as described above must be subjected to a storage process before being processed through a number of steps in a conventional regeneration filler manufacturing process. The storage tank stores most of the capacity of the concrete, It is preferred that the invention use a small capacity reservoir made of styrene.

In order to add the existing recycled raw material to the recycled raw material produced in the present invention in the storage tank as described above, about 10% of the waste recycled paper fiber prepared in the present invention is added to the recycled raw material capacity in the storage tank The present invention will now be described in more detail with reference to the following examples, which are intended to illustrate the technical point of the present invention in more detail.
