Como é feito o PAPEL HIGIÊNICO #Boravê

Summary

This video takes viewers on a detailed journey of how toilet paper is made, starting with the raw material, cellulose, sourced from eucalyptus. The process includes blending, refining, and drying the cellulose pulp, before it passes through giant machines that press and heat it into soft, thin sheets. The video highlights the importance of sustainability, with the factory using recycled materials and biomass fuel. The final product is tested for quality and then packaged efficiently. In a fun twist, the video emphasizes the scale of production, showing how toilet paper is made at a rate equivalent to three times around the Earth daily.

Takeaways

• 😀 Cellulose from eucalyptus trees is the primary raw material used to make toilet paper.
• 😀 The cellulose arrives in large 250 kg packages, with the packaging itself also being made of cellulose.
• 😀 The raw material is mixed with water in a large blender to create cellulose pulp, which is 95% water and 5% cellulose.
• 😀 The pulp is refined in a machine that increases its resistance by disheveling the fibers, improving the paper's quality.
• 😀 The paper is formed in a paper machine, where it goes through screens and felt to begin the paper formation process.
• 😀 At this stage, the paper is 99.8% water, and it is passed through a press with a vacuum to remove the excess water.
• 😀 A Yankee cylinder, heated to 140°C, helps to dry the paper further, while a jet of hot air assists in the drying process.
• 😀 Biomass fuels, such as sugarcane bagasse and rice straw, are used to heat the steam for the drying process.
• 😀 The paper is softened through tiny folds created by a scraper, which gives it a soft texture.
• 😀 Large, impressive rolls are produced, weighing three tons and measuring 85 km in length, equivalent to covering 24 football fields.
• 😀 The large rolls are then converted into smaller toilet paper rolls, with designs and texture applied through a stamping process.
• 😀 Recycled cardboard is used to make the inner tube of the toilet paper rolls, ensuring sustainability.
• 😀 Fragrance is applied to the paper during the production process to add a pleasant scent.
• 😀 Quality control is an essential part of the process, ensuring the paper meets standards for resistance and dimensions.
• 😀 The factory produces about 115,000 km of toilet paper daily, enough to circle the Earth three times.

Q & A

What is the raw material used to make toilet paper?

The raw material used to make toilet paper is cellulose, which comes from eucalyptus trees. The cellulose forms the cell walls of plants.

How is the cellulose prepared for the paper-making process?

The cellulose is mixed with water in a giant blender called a hydrapooper, which creates a pulp. This pulp contains 95% water and only 5% cellulose.

What role does the refiner play in the paper-making process?

The refiner helps increase the paper's strength by 'disheveling' the cellulose fibers. This creates more connection points between the fibers, improving the paper's resistance.

How does the paper get dried during production?

The paper passes through a press with a vacuum cylinder to pull out excess water, then it goes through a heated cylinder called a Yanke, which uses steam to dry the paper at 140°C.

What is the purpose of the tiny folds created on the paper?

The tiny folds on the paper are created by a scraper on the Yanke cylinder. These folds are what make the paper soft and give it its characteristic texture.

How large is the roll of paper that comes out of the main machine?

The paper roll that comes out of the machine is 3 tons, 2.90 meters wide, and 85 kilometers long. This roll is equivalent to covering 24 football fields.

How is the toilet paper converted into smaller rolls for consumer use?

The large roll is unrolled and, for double-ply toilet paper, two rolls are joined together with adhesive. The paper is then stamped with a design and rolled onto a tube.

What material is used to make the cardboard tube for the toilet paper?

The cardboard tube is made of macular cardboard, which is 100% recycled brown paper.

How is fragrance applied to the toilet paper?

The fragrance is applied during the rolling process. The paper is rolled up into a long 30-meter tube, and the fragrance is added before it is cut into individual rolls.

What is the daily production capacity of the factory in terms of toilet paper?

The factory produces about 115,000 kilometers of toilet paper every day, which is approximately three times the circumference of the Earth.
