2/72/7
No atual estado da técnica para tintas refratárias são comumente utilizados minerais, tais como: zirconita, olivina, magnesita, silicato de alumínio, grafite, feldspatos, etc.. Estes materiais são usados na aplicação em aços puros ou combinados em 2 ou mais minerais na mesma mistura.In the current state of the art for refractory paints, minerals are commonly used, such as: zirconite, olivine, magnesite, aluminum silicate, graphite, feldspars, etc. These materials are used in the application in pure steels or combined in 2 or more minerals in same mixture.
Em sua produção são feitas em álcool como solvente na proporção de 10 - 30%; agentes de tixotropia 2 - 15%; fixadores 0,5 - 10% e minerais 35 - 80% para serem aplicadas por meio de spray, pincel, lavagem ou imersão.In their production they are made in alcohol as solvent in the proportion of 10 - 30%; thixotropy agents 2 - 15%; fixers 0.5 - 10% and minerals 35 - 80% to be applied by spray, brush, washing or immersion.
Estas tintas apresentam bons resultados técnicos, porem pelo fato de terem muito oxido de silica livre podem reagir em alguns casos com aços manganês gerando assim defeitos em peças fundidas.These paints present good technical results, but due to the fact that they have a lot of free silica oxide they can react in some cases with manganese steels, thus generating defects in castings.
Com isso para solucionar estes problemas atualmente são usados tintas feitas com zirconita, silicatos puros ou mixados para se fundir aços carbono, baixa liga, alta liga e inox e no caso de aços manganês usa-se tintas feitas com olivina e magnesita.In order to solve these problems, paints made with zirconite, pure or mixed silicates are currently used to melt carbon, low alloy, high alloy and stainless steel and in the case of manganese steel, paints made with olivine and magnesite are used.
Em caso de tintas base água 10 - 35%, agentes de tixotropia 3 - 15%; fixadores 1 - 15% e minerais 35 - 80%, a sua aplicação pode ser feita com sucesso no caso de tintas base zirconita e silicatos de alumínio puros ou mixados para fusão de aços carbono, alta liga, baixa liga e inox.In case of water-based paints 10 - 35%, thixotropic agents 3 - 15%; fasteners 1 - 15% and minerals 35 - 80%, can be applied successfully in the case of zirconite based paints and pure or mixed aluminum silicates for melting carbon, high alloy, low alloy and stainless steel.
Para aços manganês que devem ser feitos com magnesita o grande problema é o fato da magnesita reagir com água causando o endurecimento da tinta.For manganese steels that must be made with magnesite the big problem is the fact that the magnesite reacts with water causing the paint to harden.
Na literatura patentária a PI0802952-0 de 09/07/2008 trata de um composto para retirada de tinta presente em peças plásticas e processo de aplicação deste como um composto paraIn patent literature PI0802952-0 of 09/07/2008 deals with a compound for removing paint present in plastic parts and the process of applying this as a compound for
3/7 retirada de tinta presente em peças plásticas e processo de aplicação deste que, de acordo com as suas características, propicia a partir da utilização de um composto a base de oxido de alumínio e bauxita sintetizada na forma de grãos esféricos ou grãos angulares e de um processo de aplicação específico de retirada da tinta presente em peças plásticas em geral. Esta solução trata de um composto para retirada de tinta e não de uma tinta refratária.3/7 removal of paint present in plastic parts and application process, which, according to its characteristics, allows the use of a compound based on aluminum oxide and bauxite synthesized in the form of spherical grains or angular grains and of a specific application process of removing the paint present in plastic parts in general. This solution deals with an ink removal compound and not a refractory ink.
A aplicação de bauxita e alumina fundida é conhecida na produção de refratários para fornos e panelas de vazamento, em alguns casos como 100% do refratário e em outros casos mesclados com outros produtos.The application of bauxite and molten alumina is known in the production of refractories for furnaces and pouring pans, in some cases as 100% of the refractory and in other cases mixed with other products.
Pelo fato de apresentar um alto teor de oxido de alumínio e baixos teores de oxido de silica, o alto ponto de fusão (superior a 2000C) e alem de estarem estabilizados quimicamente pela fusão nos possibilitou chegar a conclusão que poderiamos aplicar estes matérias na produção de tintas refratarias para fusão de todos os tipos de aços.Due to its high content of aluminum oxide and low levels of silica oxide, the high melting point (above 2000C) and in addition to being chemically stabilized by fusion allowed us to conclude that we could apply these materials in the production of refractory inks for melting all types of steel.
O requerente conhecedor dos aspectos restritivos das soluções atuais desenvolveu uma tinta refratária cuja nova composição química permite sua utilização em todos os tipos de aços na sua fusão.The applicant with knowledge of the restrictive aspects of current solutions has developed a refractory paint whose new chemical composition allows its use in all types of steel in its melting.
A proposta da presente invenção tem como maior novidade o fato de se ter uma única tinta tanto base álcool como base água que pode ser usadas para fundir todos os tipos de aços, acabando assim com o uso de até três tintas para fundir aços.The proposal of the present invention has as its greatest novelty the fact that it has a single ink, both alcohol-based and water-based, which can be used to melt all types of steels, thus ending the use of up to three paints to melt steels.
4/74/7
Isso elimina os problemas de mistura de produtos gerando contaminações, controle maior do processo de aplicação da tinta por ser um único produto.This eliminates the problems of product mixing generating contamination, greater control of the paint application process as it is a single product.
Os maiores problemas enfrentados atualmente são os controles de qualidade que são demandados nas tintas.The biggest problems faced today are the quality controls that are demanded in paints.
A baixa refratariedade da magnesita usada em aços manganês, o fato da mesma reagir com água causando seu endurecimento.The low refractoriness of magnesite used in manganese steels, the fact that it reacts with water causing it to harden.
No caso de aços carbono, baixa liga, alta liga e inox esta tinta substitui com superioridade os materiais feitos com zirconita pura, silicato de alumínio puro e até mesmo os que são feitos com a mistura dos dois produtos.In the case of carbon steels, low alloys, high alloys and stainless steel, this paint is a superior substitute for materials made with pure zirconite, pure aluminum silicate and even those made with a mixture of the two products.
Com a presente invenção temos a unificação de uma única tinta para fundir todos os tipos de aços e reduzindo os custos em relação as tintas convencionais utilizadas.With the present invention we have the unification of a single paint to melt all types of steels and reducing costs in relation to the conventional paints used.
