Customized insulating brick demand specification:
I. Product specifications and performance requirements
(1) Size requirements
Length: [X] cm
Width: [X] cm
Height: [X] cm
The allowable size deviation range is [x]%, so as to ensure that insulating brick can accurately adapt to the reserved space of our equipment or building structure and avoid installation problems caused by size mismatch.
(2) Density requirements
Batch density should be controlled between [x] g/cm and [x] g/cm. The lower density helps to reduce the weight of the structure, and at the same time, it ensures that insulating brick has good thermal insulation performance, which meets our dual requirements for lightweight and energy-saving equipment or buildings.
(3) Thermal conductivity requirements
At the temperature of [X]℃, the thermal conductivity shall not exceed [x] w/m k. Low thermal conductivity is the core performance index of insulating brick. Only by meeting this requirement can we effectively block heat transfer, provide reliable thermal protection for our high-temperature working environment or heat-sensitive areas, reduce energy consumption and ensure the safety of equipment and personnel.
(4) compressive strength requirements
Compressive strength should reach [X] MPa and above. Insulating brick may bear certain pressure in actual use, such as self-weight of equipment, accumulation of materials, etc. Sufficient compressive strength can ensure its structural stability in the long-term use process, and avoid the influence of thermal insulation effect and overall structural safety due to compressive deformation or damage.
(5) Fire-resistant temperature requirements
The fire resistance temperature shall not be lower than [X]℃. Our application scenario involves high temperature environment. insulating brick should have excellent fire resistance, be able to work continuously and stably under high temperature conditions, prevent potential safety hazards caused by excessive heat conduction, prolong the service life of equipment and ensure the smooth production process.
II. Chemical Composition Requirements
The chemical composition of insulating brick shall meet the following standards:
The content of Al₂O₃ (alumina) is not less than [X]%, so as to ensure that the brick has good fire resistance and chemical stability, can resist chemical erosion at high temperature, and maintain long-term stability of thermal insulation performance.
The content of SiO (silicon dioxide) is controlled between [X]% and [X]%. Too high or too low SiO content may affect the sintering performance and mechanical strength of the brick, so it needs to be accurately controlled to meet our customized needs.
The total content of other impurities shall not exceed [X]%. Too many impurities may produce harmful gases or reduce the performance of the brick at high temperature, which should be strictly controlled to ensure the product quality and the safety of the use environment.
III. Appearance and packaging requirements
(1) Appearance requirements
The surface should be flat and smooth, without obvious cracks, pores, sand holes and other defects, so as to ensure the beauty and integrity of insulating brick and prevent the strength reduction and thermal insulation performance reduction caused by surface defects.
The colors shall be uniform and consistent, and conform to the color number or sample standard specified by us. If there is no specific color number requirement, it can be produced according to the conventional insulating brick color, but it is necessary to ensure that the color deviation of the same batch of products is within an acceptable range to meet our unified requirements for product appearance quality.
(2) Packaging requirements
Each piece of insulating brick needs to be packaged separately with [specific packaging materials, such as plastic film and bubble film] to prevent damage caused by collision during transportation and storage, and at the same time, it plays the role of moisture-proof and dust-proof, so as to ensure that the appearance and performance of the products are intact when they arrive in our country.
