FAQ

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

 

Q4: What is the minimum quantity?

A4: There is no minimum order quantity. Depending on the item and processing, there may be a minimum production required, however we can offer a quotation based only on the quantity you need.


Q: Is sintering insulation brick good or concrete porous brick good?
Thermal insulation brick is functional material, it is better than porous brick in thermal insulation. At the same time, the internal heat preservation material, so the overall cost is more, the hole brick should be higher.
Q: Are insulating fire bricks resistant to flame impingement?
Yes, insulating fire bricks are resistant to flame impingement.
Q: The insulation layer destroyed after use of cement paste and tiling
The most certain and the method can increase the area of the balcony is to eradicate the insulation layer exposed after cement wall tiles.
Q: Are insulating fire bricks suitable for insulation in steam boilers?
Insulating fire bricks, which are made from lightweight materials such as alumina or silica, are highly suitable for providing insulation in steam boilers. These bricks possess exceptional insulating properties and can endure high temperatures and thermal shocks, making them an ideal choice for use in steam boilers subjected to constant heat exposure. The low thermal conductivity of insulating fire bricks effectively hinders heat transfer, resulting in reduced energy loss and enhanced efficiency of steam boilers. Additionally, their superior insulation capabilities assist in maintaining consistent temperatures within the boiler, preventing fluctuations in heat and minimizing the risk of thermal stress and damage. Moreover, insulating fire bricks exhibit resistance against corrosion and chemical attacks, ensuring their longevity and durability when employed in steam boiler applications. Furthermore, they can be effortlessly installed and cut into various shapes and sizes to perfectly fit the specific requirements of the boiler. In conclusion, insulating fire bricks are an exceptional option for insulation in steam boilers due to their ability to withstand high temperatures, low thermal conductivity, and resistance to corrosion. Their utilization aids in reducing energy loss, improving efficiency, and guaranteeing the long lifespan of the boiler.
Q: Is it possible to recycle used insulating fire bricks?
It is indeed feasible to recycle insulating fire bricks that have been used. Insulating fire bricks consist of a range of materials, including alumina, silica, and other refractory materials. These materials can be dismantled and utilized again in the creation of fresh bricks or alternative refractory products. The recycling of used insulating fire bricks aids in the reduction of the need for fresh raw materials and the mitigation of waste. Nevertheless, it is crucial to acknowledge that not all recycling centers or facilities may accept insulating fire bricks. It is therefore advisable to verify with local recycling programs or specialized recycling companies that handle refractory materials.
Q: Can insulating fire bricks be used in chimneys and flues?
Insulating fire bricks are specifically designed for high-temperature applications and are often used in furnaces, kilns, and other industrial settings. While they do possess excellent insulating properties, they may not be the best choice for chimneys and flues in residential or commercial buildings. The main reason for this is that insulating fire bricks are not as durable and heat-resistant as other materials specifically designed for chimney and flue construction. They may crack or break when exposed to the extreme heat and rapid temperature changes that occur in chimneys. Additionally, these bricks are not typically designed to withstand the corrosive effects of flue gases, which can lead to their degradation over time. When it comes to chimneys and flues, it is generally recommended to use materials such as clay flue liners, stainless steel, or refractory bricks that are specifically manufactured for these applications. These materials are better suited to handle the high temperatures, corrosive gases, and rapid thermal expansion and contraction that occur in chimneys. It is important to consult with a professional chimney or flue specialist who can advise on the appropriate materials to use based on the specific requirements and conditions of your chimney or flue system.
Q: Can insulating fire bricks be used in the construction of boilers for steam generation?
Yes, insulating fire bricks can be used in the construction of boilers for steam generation. Insulating fire bricks have excellent heat insulation properties, making them suitable for use in high-temperature applications such as boilers. They help to minimize heat loss, improve energy efficiency, and ensure safe and efficient steam generation.
Q: Are insulating fire bricks resistant to ultraviolet radiation?
No, insulating fire bricks are not resistant to ultraviolet radiation.
Q: Can insulating fire bricks be used for insulation in petrochemical plants?
Yes, insulating fire bricks can be used for insulation in petrochemical plants. Insulating fire bricks are known for their excellent thermal properties, including low thermal conductivity and high resistance to heat transfer. These properties make them suitable for use in high-temperature environments such as petrochemical plants, where insulation is crucial to prevent heat loss and maintain optimal operating conditions. Additionally, insulating fire bricks are lightweight and have good mechanical strength, making them easy to install and durable in industrial settings. They are also resistant to chemical corrosion, which is essential for petrochemical plants that handle various corrosive substances. Therefore, insulating fire bricks can effectively provide insulation and contribute to energy efficiency and safety in petrochemical plants.
Q: Are insulating fire bricks environmentally friendly?
To a certain degree, insulating fire bricks can be deemed environmentally friendly. These bricks are crafted from abundant and readily accessible natural materials like clay, shale, and other minerals. Consequently, they do not contribute to the depletion of our natural resources. Furthermore, insulating fire bricks are engineered to possess low thermal conductivity, which aids in diminishing energy consumption. By utilizing these bricks, buildings can achieve better insulation, resulting in reduced heating and cooling requirements and, subsequently, decreased greenhouse gas emissions. Nevertheless, the manufacturing process of insulating fire bricks does have some environmental repercussions. The firing process necessitates high temperatures, which can lead to air pollution and greenhouse gas emissions. Additionally, extracting the raw materials for these bricks may cause some environmental disturbances. To truly assess the environmental friendliness of insulating fire bricks, it is vital to take into account the entire life cycle, encompassing raw material extraction, manufacturing, transportation, and disposal. Furthermore, comparing them to alternative insulation materials can offer a more comprehensive perspective on their environmental impact. In conclusion, while insulating fire bricks possess certain eco-friendly qualities such as being made from natural materials and reducing energy consumption, their overall environmental impact should be assessed holistically.
