Calcium silicate bricks are among the established building materials used in modern masonry construction. In the manufacture of sand-lime bricks, raw materials such as quartz sand, quicklime and water are processed under high pressure and then steam-cured in autoclaves. It is precisely during these process steps that high thermal and mechanical stresses arise, which can lead to sticking, abrasion or damage to the brick blanks. Production downtime, quality defects and additional cleaning work are common consequences.
The Key Benefits of BRANOperl Release Paper
- Reduces the risk of sticking during sand-lime brick production and steam curing.
- The silicone-coated surface supports clean material separation and minimizes residue on products and equipment.
- Suitable for thermally and mechanically demanding processes in autoclaves.
- Helps reduce abrasion, contamination and maintenance effort within production processes.
Sand-Lime Brick Production: From Raw Material to Finished Product
The production of sand-lime bricks consists of several precisely coordinated process steps. The main raw materials are quartz sand, lime or hydrated lime and water. After mixing, the materials are pressed into brick blanks and transported into autoclaves on hardening carts.
Inside the autoclave, hydrothermal curing takes place. Under saturated steam conditions, the raw materials react and form the characteristic strength of sand-lime bricks. This curing process places high demands on all materials used during production.
Particularly critical is the risk of sticking between bricks, production surfaces or transport elements. At the same time, high temperatures, moisture and mechanical stress affect equipment and interlayers. To ensure reliable production processes, heat-resistant and silicone-coated papers are commonly used.
The Challenge: Sticking and Damage During Production
Numerous stress situations occur during sand-lime brick production. Even during transport of uncured bricks, unwanted sticking may occur. In autoclaves, heat, moisture and pressure intensify this effect further.
- Sticking between sand-lime bricks
- Damage to sensitive surfaces
- Abrasion and material loss
- Contamination inside production equipment
- Higher cleaning and maintenance effort
- Production interruptions and quality issues
Especially in automated production lines, these problems can significantly affect process reliability, efficiency and product quality. Therefore, companies rely on high-performance release papers with reliable anti-stick properties.
