No processo de fabricação de papel, após a cobertura da superfície do papel com a suspensão de amido, podemos utilizar outras tintas para revestir o papel conforme os requisitos especiais dos clientes.
Esse tipo de tecnologia de revestimento geralmente é aplicada ao papel utilizado em revistas, marcas comerciais, catálogos, livros ou embalagens.
O papel cuchê (também conhecido como papel esmaltado, papel brilhante ou papel deslizante) é um papel que recebeu uma cobertura de uma mistura de materiais ou polímeros para atribuir certas qualidades, como peso, brilho superficial, suavidade ou redução da absorção de tinta.
Diversos materiais, como caulinita, carbonato de cálcio, bentonita e talco, podem ser utilizados para revestir o papel e obter uma impressão de alta qualidade.
É a mesma situação que a dos lodos de amido. As tintas de revestimento não tratadas contêm grandes quantidades de impurezas que podem causar problemas de entupimento nas máquinas e afetar a qualidade dos produtos finais.
Esses líquidos, assim como a pasta de amido, podem obstruir o bico de pulverização e interferir no revestimento eficaz do papel. Além de danificar o bico, isso resulta em uma pulverização desigual na folha de papel, o que provoca a rejeição dos lotes.
O uso de tintas de revestimento não filtradas aumentará os custos de manutenção e o tempo de inatividade das máquinas. Além disso, a produtividade e a eficiência podem ser afetadas pelos equipamentos danificados.
Existem diferentes filtros para diferentes líquidos de revestimento, dependendo de suas respectivas características. Para líquidos de tinta de baixa viscosidade (viscosidade dinâmica ≤ 1 MPa.s) e líquidos solúveis em água, a bolsa filtrante é uma opção perfeita.
Quando se trata de líquidos de alta viscosidade, recomendamos enfaticamente o filtro autolimpante de raspagem (tanto do tipo interno quanto externo), o filtro hidráulico e o filtro autolimpante pneumático para a filtração.
Além da função básica de filtrar líquidos de forma contínua, eles podem remover eficazmente impurezas e contaminantes de líquidos de alta viscosidade em comparação com outros filtros.
Ao selecionar um filtro adequado, os fabricantes podem obter líquidos de revestimento de maior qualidade e mais puros, e todo o processo de produção pode ser mais fluido, sem interrupções.
O papel cuchê é necessário para produtos de impressão delicados. A alta qualidade é essencial e crucial para o papel original, o que exige que os fabricantes produzam papel cuchê com perfeição. As tintas de revestimento não filtradas podem influenciar negativamente todo o processo de produção e a qualidade dos produtos finais.
A Brother Filtration pode oferecer tanto bolsas filtrantes quanto filtros autolimpantes e filtros hidráulicos para líquidos com diferentes níveis de viscosidade.
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…
