Typical FRC extruded profiles using 3e Technology

 

3e - What does it mean?

e - for ecology

clean, environmental-friendly

e - for extrusion

hollow-core lightweight products, high output rates

€ - for €conomy

low capital investment and production costs

 

FRC Production Process

3e Technology

 

• Raw material dosing

• Weighing

• Batch Mixing (dry & wet)

• Continuous proportioning

• Extrusion

• Handling (wet side)

• Curing

• Handling (dry side)

 

• Grinding (if needed)

• Cut-to-length

• Strapping & storage

 

Material Compositions

The 3e Matrix can be made up of a combination

of different materials, e. g.

• cement, limestone powder, flyash

• fibers (a.r. glass fibers, cellulose and other natural or man-made fibers)

• silica, mica

• water

• additives

Händle can determine the ideal matrix by tests in lab and pilot plant.

STRONG

 

site, reducing overall weight of construction

High loadbearing capacity and tensile strength, combined with non-combustibility

 

 

Reduced building costs due to low material costs, minimum waste and speedier construction with fewer trades

CLEAN Panel installation virtually dry, due to surface smoothness no need for surface rendering, precise

cut-to-length from factory

 

ENVIRONMEN- TAL-FRIENDLY

 

Minimum noise, dust and construction waste, use of recycled materials in manufacturing process.世聯翻譯公司完成大自然介紹英文翻譯
