Description
Technical field
The present invention relates to the method for papermaking, especially use the production method of Ramulus Mori papermaking.
Background technology
Mulberry tree is a kind of perennial woody plant.Ramulus Mori is exactly the branch of mulberry tree, and Ramulus Mori is made up of bast and xylem, and the bast pectin content is higher.China's planting mulberry and breeding silkworm are with a long history, are first big countries of world's planting mulberry and breeding silkworm.People keep limitting more all the year round in great numbers not waning for making mulberry tree, often need cut mulberry tree to cut down integer, cut in general 1 year and to cut down Ramulus Mori 1-2 time, and one mu of mulberry field can shear off about 7000 of Ramulus Mori, and weight is about 700 kilograms, and therefore, China can be described as and abounds with Ramulus Mori.At the rural area Ramulus Mori mainly as fuel.
China is a papermaking big country and has long history.Paper making raw material is mainly based on timber, careless class, bamboo wood.Its paper technology is because of the different differences slightly to some extent of raw material.The basic technology of its timber papermaking is: cut-out → boiling → bleach → pull an oar → copy paper.Though Ramulus Mori belongs to timber, but also papermaking, but because of the Ramulus Mori raw material is difficult to collect and stores is because of the particularity and the physical characteristic of Ramulus Mori chemical composition determines, because of immature the knowing of Ramulus Mori paper technology, so Ramulus Mori can not come papermaking with the basic technology of timber papermaking.
" Chinese papermaking " the 1st phase of calendar year 2001 magazine discloses " storage of Ramulus Mori and pulping and paper-making performance " literary composition for the 65th page, this article has been introduced the lab scale technology of Jiangxi Province light industry research institute with Ramulus Mori papermaking, and its technological process is: Ramulus Mori → pulverizing → boiling → pull an oar → join and copy.Though this technological process is feasible, owing to adopted cooking process, energy consumption is still high, pollution is still big, haves much room for improvement.
Summary of the invention
Technical problem solved by the invention is to provide a kind of method of Ramulus Mori papermaking, for Ramulus Mori is sought a new Application Areas, for paper-making industry provides a kind of new technology and raw material.For solving the problems of the technologies described above, the invention provides a kind of is the papermaking process of raw material with Ramulus Mori.
The present inventor once was engaged in production technology work for many years in the paper mill, be that raw material carried out repeatedly papermaking lab scale and pilot scale with Ramulus Mori once, had now invented a kind ofly to be the papermaking process of raw material with Ramulus Mori, and was effective.
A kind of is that the technological process of the papermaking process of raw material is with Ramulus Mori: Ramulus Mori → pulverizing → scurf removing → bleach → pull an oar → copy paper.
Ramulus Mori needs to store sometimes, because the physical characteristic of Ramulus Mori and chemical composition decision, Ramulus Mori is stored relatively difficulty, storage procedures can adopt traditional gravity-flow ventilation airing to store, also can spray the medicine mildew-resistant stores, also can adopt immersion to store, the so-called immersion stored, and soon Ramulus Mori is immersed in the clean water and stores.
Pulverize, be about to Ramulus Mori and pulverize, adopt special mechanical equipment,, Ramulus Mori is ground into 20-60 purpose bits, now name these bits to be the Ramulus Mori bits as pulverizer, saw etc.In the Ramulus Mori bits, the bits of Ramulus Mori xylem can be called mulberry branch wood chips, and the bits of its Ramulus Mori bast can be the Ramulus Mori scurf title phase.
Scurf removing is promptly removed the Ramulus Mori scurf.When Ramulus Mori was pulverized, Ramulus Mori scurf and mulberry branch wood chips mixed, and papermaking is to utilize mulberry branch wood chips, therefore, needed the employing method that mulberry branch wood chips is separated with the Ramulus Mori scurf.Can adopt " floatation " that the Ramulus Mori scurf is separated with mulberry branch wood chips.So-called " floatation " is about to the Ramulus Mori bits and is soaked in the water, because of the proportion of the Ramulus Mori scurf proportion less than mulberry branch wood chips, and bubbles through the water column, and adding water can overflow the Ramulus Mori scurf, thereby realizes separating of mulberry branch wood chips and Ramulus Mori scurf.
Bleaching is about to mulberry branch wood chips and bleaches.Bleaching can be adopted bleaching in stages, promptly according to the kind requirement of copying paper, divides and bleaches several times.Bleaching agent can adopt caustic soda, hydrogen peroxide, urea etc.
The Ramulus Mori slurry is made in making beating, the mulberry branch wood chips after promptly will bleaching with beater.Sometimes also according to the kind requirement of copying paper, join slurry.
Copy paper, promptly adopt paper machine that the Ramulus Mori slurry is made needed paper.
The invention solves with Ramulus Mori is the technical barrier of raw material papermaking, has found wide outlet for the application of Ramulus Mori, makes growth of agricultural efficiency, increasing peasant income.In the production method of this papermaking, omitted traditional cooking process, greatly reduce industrial pollution, greatly reduce the cost of papermaking, improved economic benefit of enterprises, simultaneously, can save a large amount of timber resources, have good ecological benefits and social benefit.
