What is lightweight insulation castable? Lightweight thermal insulation castable is castable made of aluminate cement, high-aluminum fine materials, ceramsite, and a number of additives that are lightweight, fire-resistant, and heat-insulating.
Characteristics of lightweight thermal insulation castables. Lightweight thermal insulation castables have acid corrosion resistance, temperature resistance, thermal stability, convenient construction, light volume, and high compressive strength. It has the characteristics of acid and acid gas corrosion resistance, heat insulation, heat preservation, and low water absorption. Easy construction and strong adhesion. It has a long initial setting time and construction operability time, rapid strength growth, and strong impermeability. No acidizing treatment is required, and it is easy to ensure the density and fullness of the masonry mortar joints. It can significantly improve the air tightness and integrity of the chimney lining wall and the anti-corrosion ability of the lining.
Application of lightweight insulation castables. Lightweight insulation castables are often used in areas with alkali corrosion resistance at high temperatures. Such as tall chimneys, high-temperature flues, and air duct linings. It is also used in acid-resistant projects such as acid-resistant pools and tanks in petroleum, chemical, non-ferrous metallurgy and other industries.
The impact of lightweight insulation castables on the castable industry
As a highly practical refractory material, lightweight insulation castables play a very important role in the industry. At the same time, our country cannot lack the existence of such products. Now, as our country develops faster and faster, the demand for lightweight insulation castables industry is also increasing, causing domestic production companies to continue to emerge. So it should be possible to guess that in the future, this lightweight insulation castable in the market will concern by many users, consumers, and other industries. It also had a huge impact.
With the rapid development of refractory castables, many new species are also constantly increasing. But this does not mean that the quality of the product cannot be guaranteed. With the addition of categories, the quality of products has also improved, and many new refractory raw materials have also been developed. Rongsheng Refractory Materials Manufacturer is a refractory material manufacturer dedicated to comprehensive refractory material services. We have multiple production plants. Refractory material products cover a variety of high-quality refractory brick products, unshaped refractory castable products, refractory precast shapes, etc. Our technical team and construction team fully guarantee the performance and construction of refractory materials, and the quality of the refractory lining is also more guaranteed.

Lightweight thermal insulation castables are composed of thermal insulation lightweight aggregate and powder, binders, and admixtures. Generally speaking, the bulk density of castables is less than 1800 kilograms per cubic meter. Its total porosity is greater than 45%, and its linear change on heating is less than 1.5%, which is also called light insulation castable.
The lightweight thermal insulation castable has the characteristics of low volume density, low thermal conductivity, and good thermal insulation function. There are many types of lightweight insulation castables. Generally speaking, they are classified by lightweight aggregate varieties and production methods. Lightweight thermal insulation castables are mainly divided into lightweight brick and sand castables, porous bricks, hollow balls, ceramics, and Rongsheng ultra-lightweight thermal insulation castables.
In the past, lightweight insulation castables were used for the insulation layer of casting furnaces with temperatures above 1000°C. It cannot come into direct contact with flames. Nowadays, light insulation castables can be used in heating furnaces with temperatures up to 1800°C, and some castables can be applied to job linings.
Lightweight insulation castable is an important raw material in the industrial industry. If the quality of the selected products is not up to standard, resulting in substandard industrial products, I am afraid that the gain outweighs the loss.
Now, the lightweight insulation castable market is so good, that it will promote the development of the entire industry. Therefore, Rongsheng monolithic refractory material manufacturers will also seize this opportunity. We strive to provide more efficient services for high-temperature industrial furnaces in the field of unshaped refractory materials and lightweight insulation castables, so as to save production costs and improve economic benefits for enterprises.
To purchase high-quality lightweight insulation castable products, please choose a competent refractory material manufacturer. Not only can you enjoy fast delivery and high-quality refractory products, but you can also enjoy comprehensive customer service.
