Description

"PAPER RECYCLING PROCESS FOR MAKING RECYCLED PAPER SHEETS APPLIED IN EQUIVALENT CRAFTS AND RESULTING RECYCLED PAPER".

TECHNICAL FIELD

The present invention is a paper recycling process for making recycled paper sheets applied in handicrafts and equivalents, and more specifically said recycling process is based on recipes and steps having as main inputs used paper sheets and natural products. such as sugarcane fibers, bark, seeds, aromatic essences, wool, kraft paper and newspaper; The resulting producer, ie the sheets of paper, are intended for the application and shaping of various products and parts, such as lamps, pictures, picture frames, notebook covers, pencil holders, cases, baskets and many others.

TECHNICAL BACKGROUNDS

In general, paper recycling has been an activity that has been developed for decades, but more recently, especially aimed at the large paper-producing industries. To get an idea of the growing market, according to the Brazilian Pulp and Paper Association (Bracelpa ), in Brazil, the consumption of chips (the raw material of recycled paper) grew 56% from 1997 to 2006, while paper consumption grew 24.9% in the same period. Which means there is a higher production of recycled paper. Of the 175 paper producers installed in the country, 75% have more than 50% of their recycled products.

Based on the data described above, it is understood that paper recycling is performed by large equipments that use complex processes based on chemical products. However, it is known that the recycling of papers has simpler origins, that is, it is a secular knowledge to use paper as a source for the development of other materials, such as, for example, paper "mache", a technique that uses a mixture of glue paper. and starch, resulting in a hardwearing dough with a dry, textured and rustic finish where surprising results can be obtained in the creation of utility and decorative objects.

The major difference between industrial and artisanal recycling processes lies in the fact that industrially recycled paper requires the use of various chemicals to remove paper impurities such as inks and glues, which for some critics can also be hazardous to the environment if not done correctly.

On the other hand, the homemade production of paper "machè" configures low production with a lot of work, restricting its application to artists and people who work with crafts.

BRIEF DESCRIPTION OF OBJECT

Aiming, therefore, to contribute to the recycling of paper to produce parts and products in a more productive line, but without the use of chemicals and harmful elements in the environment, while the innovative process allows to differentiate from the handmade and homemade process, such as "papermarche", the applicant has developed a new paper recycling process which utilizes some steps which may result in recycled papers with varying shapes and compositions resulting, for example, in a white recycled sheet, free from fibers and sempigments, or resulting in a recycled paper sheet. natural fibers with or without pigments, which results in different final sheet configurations.

One of the great advantages of this process is its natural procedure, that is, without the addition of chemicals harmful to the health of the worker and without harming the environment.

Another great advantage is the abundant production of leaves of various compositions that allow those working in the manufacture of parts and products a variety of choice, expanding their work options.

Another advantage derived from the process in question is the possibility that it can be done by people of various ages and social classes, especially those who participate in social, educational and pedagogical projects carried out by associations, neighborhood organizations, cooperatives and so many other socio-economic groups that generate personal sustainability. of the most varied social fields, since the process in question is easy to assimilate and high production, allowing to reverse the practical actions in economic actions.

DETAILED OBJECT DESCRIPTION

With reference to the illustrated drawings, the present invention relates to a new "PAPER RECYCLING PROCESS FOR MAKING RECYCLED PAPER SHEETS APPLIED TO HANDICRAFTS AND EQUIVALENTS", more precisely, said paper recycling process (1) is intended for making from recycled paper sheets (2) used in the manufacture of parts and products, but without the use of chemicals and elements that are harmful to the environment, at the same time that the innovative process allows us to differentiate from the home and home process.

According to the present invention the paper recycling process (1) for making recycled paper sheets (2) comprises the following steps:

STEP 1: Production of white recycled sheet without fibers and sempigments, the following procedures are followed: la) selection: for recycling only used white sheets of paper, graphics shavings, used notebook sheets, are not used newspapers, magazines or paraffin papers for pulp making; lb) cleaning - after collecting the papers, the process of cleaning begins, separating any residue attached to the paper, such as: tape, clips, staples, other adhesives, etc;

l.c) disinfection: the paper separated in the previous procedures should be shredded in medium pieces and placed in a clean water sauce with bleach, remaining in this "sauce" for 12 to 18 hours; At this stage, the process is cleaning and cleaning, allowing that through this "soak" the paper is cleaner, ie pen, printer inks or carbon writing are dispensed in this process; (Clean water can come from the reuse of water rain, which can be captured at the workplace for water changes and paper washing).

l.d) washing: this procedure has the function of washing well the paper, eliminating impurities and offering quality to the massesultant; The paper should be drained through a sieve and washed thoroughly under running water. exchanging the water containing sanitary water for clean water, allowing the whitewash paper to advance to the next liquefying procedure;

l.e) shredding: put the paper in the "sauce" together with clean water and shred for 60 seconds;

lf) mixing: once ground, the whole mass with water goes to a mixing tank, starting a 5 minute beating process with glue insertion, as described in the process below, if the mass is too heavy according to the peel evaluation, he adds. more water;

lg) introduction of akd glues (alkyl ketene - glue synthetic dimer that allows alkaline internal bonding, ie it has the purpose of controlling liquid penetration in the paper after drying) and cmc (synthetic product that has the purpose of dispersing the fibers during the act of paper making; also having the function of external alkaline takeoff) - procedures

1.g.1) dilution of powdered glues: cmc - 1 cup of powder for 5 liters of warm water and akd - 2 cup of powder for 5 liters of warm water;

1.g.2) In the mixing tank, add 1 mug of akde cmc glues (ready made) and beat for 5 minutes; ph damassa (sharp acidity or alkalinity) should be checked, keeping it close to the next so as not to compromise the mass;

h) sieving: remove the mass from the tank and sift all the pulp, draining all the water.

By the end of STEP 1, it is already possible to obtain enough pulp for the production of white and non-fiber recycled paper, similar to that found on the market and produced industrially.

STEP 2: From the ready pulp, it is possible to make recipes by adding to it, peels of garlic, onion and other roots, sugarcane bagasse fibers, kraft paper, newspaper, wool, flaps, seeds and other essences, as well as natural pigments and dyes. for dyeing all sheets (paints, aniline and even natural pigments). To conform this step, the following procedures are foreseen:

2.a) Dyeing of fibers and peels: For dyeing fiber dacana, garlic peel, onion peel and sisal, follow all steps below:

2.a.1) Put in a stainless steel pan, high pressure cooker for 30 minutes (set the time after opening boil), turn off the fire and let it cool naturally, ideally after 12 hours;

2.a.2) When disconnecting, 600 ml of aluminum desulphate which acts as a "mordant" for dyes should be added immediately, improving pigment retention and facilitating internal bonding, improving sheet formation and controlling the appearance of spots on paper; dilute 6 tablespoons of aluminum sulfate (approximately 300 grams) in 10 liters of water.

2.b - Addition of Natural Fibers:

2.b.l - Sugarcane bagasse fiber cooking (residue):

- In a 100L pan, put the sugarcane bagasse.

- Add water to cover it

- Add lye of caustic soda and 300ml of soda ash

- Cook for 5 hours and stir every 30 minutes.

- Turn off the fire and wait for it to cool.

- Pour into sieve and wait for water to drain

- The washing process is essential, because if there is any trace of caustic soda in the fiber, then the paper will not absorb and fix the color.

2.c - Dyeing of recycled paper pulp in the six pack (when paper is pure, without natural fiber)

2.C.1- Add 30L of water, dye (nontoxic fabric dyeing powder) and 300ml of Aluminum Sulphate.

- Crash for a few minutes

- Pour into sieve and wait for water to drain

- Reserve the dyed pulp for later preparation of the paper sheets.

2.d- Dyeing of recycled paper pulp in the blender (when there is sugarcane fiber in the paper) 2.d.l - Putting 20 L of water in the blender

2.d.2 - Add 2L of unpainted ready-made pulp2.d.3 - Add 1 liter of cooked and washed cane fiber IL, non-toxic dye powder, 300ml Aluminum Sulfate2.d.4 - Crash for a few minutes2.d.5 - Pour into the sieve until all the water runs out

2.d.6 Reserve already dyed pulp for subsequent preparation of paper sheets.

STEP 3: PAPER MAKING

3.a - In a water tank of 1000 liters, pour half water (500 liters) put the dyed or white ready pulp and stir until homogeneous for approximately 5 minutes:

3.b - Insertion of the shells, seeds, grains will be placed in the water tank mixing the pulp; The responsible person or papermaker will know whether or not to add more bark or other inputs, allowing the sheets of recycled paper to have little or a lot of fiber, fiber, etc .;

3.c - In a canvas size 66cm χ 96cm, the papermaker removes paper by dipping the screen into the water box, calculating texture, weight and details of the paper.

STEP 4 - PAPER DRYING - If there is sun the paper will dry in 3 hours, this time is the limit for the sun drying process, after this period if the sheet remains in the sun, the paper will discolor; In the event of rain, rain or cloudy weather drying can reach up to 24 hours, so it is recommended that this process be done inside a closed greenhouse.

The parameters to remove the paper ensuring full drying will be the observation of shades, because the dough always becomes much lighter when dry; Another sedative parameter by touch / touch really allows one to feel the dry or wet state of the leaf.

All screens used should be stored in a place where they are not exposed to the sun or rain. STEP 5 - SCREEN PAPER DRAWING - From the bottom of the screen (ie the back of the paper) push the sheet apart by hand so that it easily With a knife, the edges of the paper are contoured, making it easy to tear off the entire sheet. This action requires a great deal of skill and delicacy for the leaf to come out without any torn parts, as everyone has an oversized edge even allowing them to be trimmed.

STEP 6 - PAPER STOCK - Once the recycled paper sheets have been removed, they are routed to a stock, placed on top of each other, preferably on a table or any straight surface in a dry, airy environment, but not in contact with the sun, if this contact is daily the paper will fade.

Currently the daily production is of sheet size 66cm X 96cm obtaining in its catalog the following models and colors, in the original size (examples in figures 2, 3 and 4):

- Line "white paper" with fiber or peel in 35 colors.

- White line without fiber and without shell.

- Line "white paper" with wool and seeds.

- Scented paper line

- Colored thread with fibers or shells (35 colors)

- Raw cane line, bark, wool and essence.

Papers made in the form of pasted sheets are properly cut and applied in the creation of pieces (lamps, pictures, notebook covers, pencil holders, cases, blocks, folders, scratch and doodles, paper collection baskets, cards, card holders, etc. .).
