O livro que lemos, o lenço de papel que usamos, os documentos que imprimimos -tudo isso se realiza com a ajuda do papel.
Utilizamos este produto há séculos; nossos ancestrais também usavam o papel para pintar e gravar. Alguma vez você já se perguntou como o papel é fabricado? Como pode tornar-se tão macio e flexível a partir da madeira?
Há várias etapas na produção de papel e celulose, desde o corte da madeira até a fabricação da polpa, e da fábrica de papel até a embalagem. A pasta de amido utilizada no processo, no entanto, é um dos procedimentos mais cruciais que abordaremos neste artigo.
O papel beneficia-se enormemente do amido, pois confere tanto a gramatura quanto o revestimento ao papel. O papel é fabricado com amido há mais de 6.000 anos. O custo de produção do papel é significativamente menor quando se utiliza amido.
Para obter as moléculas necessárias para a aplicação, o amido é fervido e hidratado. A água e outros produtos químicos são combinados para criar uma pasta de amido, que possui as qualidades necessárias para o revestimento por pulverização.
Além disso, atua como um dos aglutinantes na formulação do revestimento do papel, que consiste em uma mistura de pigmentos, aglutinantes e espessantes. A suavidade, rigidez, brilho e o lustre do papel revestido foram aprimorados, o que melhorou suas propriedades de impressão.
Na produção de papel, a pasta de amido não tratada pode causar vários problemas. O mais direto é a superfície irregular do papel. Além disso, devido à baixa qualidade da pasta de amido, a qualidade do papel pode ser afetada.
Além da baixa qualidade dos produtos finais, a pasta de amido não filtrada também pode afetar os equipamentos de produção, que ficam facilmente obstruídos por impurezas e partículas de amido não dissolvidas na pasta.
A melhor solução para a filtração de lodo de amido é o filtro autolimpante, que pode fornecer filtração de líquidos contínua e ser instalado na linha de produção sem afetar o equipamento original.
Utilizando um filtro autolimpante automático, os fabricantes podem obter facilmente lodo de amido de alta qualidade e remover as impurezas granulares maiores.
Antes da pulverização na fábrica de papel, os grãos finos e as partículas de amido não dissolvidas são eliminados por um filtro autolimpante da Brother Filtration. É crucial livrar-se dos contaminantes de maior tamanho, pois eles entupiriam o bico de pulverização e reduziriam a qualidade do papel.
A pasta de amido é um processo crucial para a indústria de celulose e papel, sendo necessária uma filtração adequada nesta etapa.
A Brother Filtration possui a capacidade de oferecer diferentes tipos de filtro autolimpante para filtração de líquidos, que podem reduzir o tempo dos lotes e diminuir a manutenção manual.

The ocean occupies most of our planet, and desalination has been used more and more widely over the past 20 years. By using reverse osmosis systems, we help desalination plants to do their job and further help more plants to solve the problem of water shortage.
Every chemical plant is inseparable from industrial water filtration systems. Whether it is the purification and filtration of raw materials and final products or the treatment of industrial wastewater and unwanted chemicals generated during the production process, industrial filtration is a top priority.
Most petrochemical industry products are stored in large containers, such as diesel, gasoline, and fuel oil. This type of storage is highly likely to lead to impurities in the products and affect the product quality. Our mission is to offer efficient and reliable filtration systems for the petrochemical industry so that purification is not a big challenge.
The extremely rapid growth of the pharmaceutical industry has created a greater demand for industrial filtration. Whether it’s upstream cell fermentation, purification, or filtration, we can provide the solution. In addition, We are committed to filtration and separation, protecting the reliability and safety of production equipment.
The food and beverage industry is closely related to the daily life and health of each of us. Therefore, we must meet higher standards to filter these products. As your experts, we help you improve product quality, reduce production costs, and safeguard everyone’s health.
Nature itself has the ability to treat wastewater. But with the huge increase in human production and living activities, it can no longer handle such large amounts of wastewater. We, as industrial treatment producers, help nature to share the burden of wastewater treatment.
Industrial wastewater from mining activities contains high volumes of heavy metals, particulates, and residual chemicals. Wastewater must be purified and filtered in order not to pollute our water resources. We help your plant meet wastewater discharge standards.
In order to extract oil more efficiently and conveniently, large amounts of water must be injected underground to ensure water pressure. And since precious water resources are limited, our technology allows wastewater to be purified so that it can be reused.
When it comes to marine filtration, the first scene that appears in people’s is usually the sea or seawater. But marine filtration is more than seawater. A crucial resource on this planet is seawater. Large amounts of seawater are needed to generate fresh water for drinking and irrigation in locations with a lack of fresh water, just as ships sailing on the ocean need a lot of it for ballast water to keep the ship balanced. Marine filtration is not only about the seawater, but also the transported seawater. The ballast water is a kind of transportation of water. The cargo ships load the seawater from one place and discharge it at another port. The seawater traveled with the cargo ship in ballast tanks. This is the point many people will be indifferent about, the filtration before the discharge of the ballast water. People are familiar that we can not drink seawater directly, because it contains large quantities of salt and contaminants. But why do we need filtration for ballast water? it is just the seawater discharge into seawater. With the development of the environmental protection concept and the perfection of the law, we are constrained to filter the ballast…
The science and practice of extracting metals or metal compounds from minerals and transforming them into metallic materials with specific qualities using a variety of processing techniques is known as metallurgy. With the development of technology and the metallurgy industry, the filtration market in this area grows quickly annually. The need for filtration is increasing and the filter equipment is also developing. In the metallurgy industry, the rolling mill coolant and lubricate system need a filtration system. Equipment coolant and lubricating oil need to be filtered to remove contaminants and accomplish recycling in the metallurgical process in order to save input costs. Filtration can help to extend equipment service life and help equipment stay at optimum level. Based on their different filtration needs and characteristic, they have respective suitable filtration elements. For the rolling mill coolant system, continuous filtration is crucial, so the automative self-cleaning filter is a great choice for this system. When it comes to the hydraulic and lubricating system, the most important point is to remove the tiny metal debris and other impurities generated due to thermalization. Depth filter cartridge can be the best choice for this operation, which can effectively eliminate the undesired micro impurities. Brother Filtration,…
The Paper industry has a centuries-old history, our ancients used the traditional way to produce paper, and now we use advanced technology to produce more delicate and high-quality paper for all kinds of uses. The tissue, the printing, publication, and the packaging, all need paper. Behind the pliable and smooth surface of a piece of paper, there are many procedures that need filtration. The starch slurry, which is the primeval form of the paper requiring filtration to improve the quality and eliminate the undissolved starch particles. The exquisite coated paper, you often find in magazines or the first few pages of a book, is processed by the coating technology. The coating paints also need to be filtered. According to the viscosity level, there are different types of filters suitable for low-viscosity and high-viscosity liquids. Water is the basic and key resource for many industries, pulp & paper is no exception. Using a filtration system to filter lakes or rivers’ water is a cost-effective way to do water resources management. Additionally, wastewater can be reused and lawful discharged after filtration. Filtration plays an important role in the pulp & paper industry, infiltration for this field, automative self-cleaning filter is the most…
