asbestos shingles production line

Asbestos shingles production line introduction:
 
Asbestos fiber cement corrugated shingles and calcium silicate board are the most popular building materials worldwide. It has been many years since their development and production. As lightweight roofing materials, they share a big market. Fireproof, dampproof, corrosion prevention, heat preservation, heat resistant, cold resistant, sound insulation, electricity insulation. Used as roofing sheets, they could cover smoothly, connect closely. Service life is more than 30 years.

Asbestos cement products are made of Portland cement, asbestos fiber, alkali-free glass silk and pulp, etc. Simple production process, low labor density, easily available raw material makes it an opportunity for rural surplus labor forces, laid-off workers.

Our factory uses the international latest technology to produce fiber cement corrugated shingles. According to national standard, our asbestos shingles production line is categorized into big wave machine, medium wave machine, small wave machine. Our product is your first choice when you want to buy fiber cement shingles production line.

Production process:

There are different ways of manufacturing asbestos cement products: molding process, dry process, wet process, wet mechanical process. The wet mechanical process can mass produce varied shapes by the addition of mechanical operations to the basic process.

Factors influencing asbestos-cement products include manufacturing process, composition, forming pressure, method of cure, and environmental conditions.

Generally, the long asbestos fibers or higher percentages of fibers will produce higher strength properties.

By using higher curing pressures or forming pressures, increased density can be achieved which in turn produces higher strength properties. The higher density products are less porous and sometimes give the effect of improving chemical resistant properties.

Manufactured from a mix of asbestos fibers and hydraulic cement, asbestos cement roof shingles are rigid, durable and fireproof. They would not warp or rot and are resistant to damage caused by insects. For decades asbestos roof shingles are considered an invaluable resource offering a superior, inexpensive alternative to traditional roof coverings.

Asbestos cement combines the advantages of both cement and asbestos. Cement has a strong compressive strength and a weak resistance to tension, asbestos is just opposite. As a compound building material, asbestos cement is popularly used for ceiling & roofing shingles.
