How to Choose the Right Binder for Building Shaped Refractory Bricks ?

Finding the right binder for building shaped refractory bricks is a complicated task. One cannot simply pick any refractory binder as the chosen binder has to be an appropriate match with the qualities of the refractory raw materials utilized in the process. Several factors need to be considered as they play a crucial part in choosing the suitable binder to build shaped refractory fire bricks. 

But before going into the factors, one needs to know about refractory bed material.

In layman's terms, refractory materials are artificially made non-metallic substances with a pretty high refractory temperature, around 15800 degrees or more. Various products created for specific purposes, which then need to undergo different processes depending on their requirements, are some of the common examples of refractory materials.

Before you go to the refractory bricks manufacturers in India, here are factors that need to be considered beforehand.

There are five procedures in shaping refractory materials. These are preparation of the input materials, raw materials combining, drying, burning, and shaping. Binders are available according to various formulations, which enhance the strength property of the material. Several ingredients are included for this: PVA, Molasses, Dextrin, CMC, and many more. And while these ingredients surely enhance the strength of the final product, they can also decide to select the binder difficult, as the binder has to work well with these ingredients and not hamper the procedure.

Choosing the Right Match

One must select a suitable binder to work with the raw materials as not every binder is ideal for every raw material. For example, there are acidic binders, including phosphoric acid, aluminum sulfate, and others, and are employed for aluminum silicate and corundum. In addition, alkaline bases like magnesium, magnesium chromium, and magnesium-aluminum can be used.

The appropriate binder must be chosen to get the best possible result.

Firing the Product is Crucial.

Provisional binders like pulp waste liquid, starch, dextrin, and many others, can be used in machine-pressed refractory materials. But for those materials that are non-fired machine pressed, a durable binding agent is required.

Adaptability is another crucial factor to consider.

One cannot simply select a binder for building shaped refractory bricks without even considering the adaption of the construction process. Some binders can easily induce hydration joining, and in the case of them, chemical bonding has to be used in constables.

Other significant factors might tilt your decision one way or another.

• A binder should never interact with the refractory mixtures, no matter whether the temperature is extremely high or significantly low.
• The binder must only release as little residue as possible during the firing process.
• The right binder would not affect the refractoriness of the brick.
• The binder must not be poisonous.
• The binder used in the process should not pollute the environment.
• During the burning process, the binder should easily burn.
• Cost is also a significant factor in deciding the right binder.
• The right binder should not affect the lasting linear change of the brick.

Why is it so essential for one to select a suitable binder to build shaped refractory bricks?

For a refractory company in India, it is essential to select the appropriate binder to get the best possible result for all their efforts after completing the process.

By selecting the right binder, Fire Brick manufacturers in India can increase production yield and lower operating costs. In addition, they can conserve energy used during the process while significantly improving the quality of the finished material.

 

Additional Information About Fire Bricks 

Fire Brick - Imitation diamond obtained from natural raw materials, by steam roasting or heat treatment. Material grades have different indicators of moisture and heat resistance and are manufactured for different purposes. 

Types of Refectory Fire Bricks

For the device of the hearth, a heat-resistant stone is required, which is known as oven bricks... The material has a high thermal inertia and the ability to store a large amount of heat.

There are four types of fire bricks.

1. Quartz Bricks- made from sandstone or quartz by firing. The stone is homogeneous, withstands high temperatures, but does not tolerate the effects of alkali or lime.
2. Carbonaceous Bricks- material obtained by pressing coke. It is used in blast furnace production.
3. The Main One - has an industrial purpose, is made from a mixture of magnesia.
4. Alumina or Fireclay - is used in the manufacture of clay in comparison with the production of quartz. The material tolerates heating up to 1000-1300 degrees and is resistant to the action of alkali and lime.
