Kitchen, toilet, GRC exhaust channel and glass magnesium plate exhaust duct advantages and disadvantages, and cost performance comparison?
GRC light material exhaust flue defects:1, the process of artificial prefabrication is prone to uneven wall thickness of the finished product, resulting in low strength of the flue pipe, brittle, and flexible, shock resistance is not up to standard.2, artificial prefabricated smoke exhaust Road, low fire resistance, fire prevention is not up to standard, extremely safe and fire hazard.
Advantages of GRC light material exhaust duct:1, the mechanization of prefabricated flue fireresistance reached more than 1.5h, the vertical bearing capacity of more than 121KN (the national standard for more than 90KN). Flexible impact resistance, stable performance, meet the requirements of national standards.2. The ventilation pipe is suitable for all kinds of building indoor exhaust and smoke exhaust. Compared with the traditional flue, it has the advantages of high strength, fire prevention and moisture resistance, light volume and installation.3 、 size can be adjusted according to the floor height and displacement. The variable type dual exhaust, effectively prevent leakage and between floors, intrusion phenomenon.
GRC is a lightweight flue sulphoaluminate cement with alkali glass fiber cloth or ordinary portland cement with wire mesh and other materials prefabricated increase airway row, completely change the ills of the traditional brick flue, it uses lightweight high strength composite materials and processed by the scientific and effective use of the advanced technology of flue gas the emission, and has the advantages of simple construction, low cost, reasonable occupation of indoor space, has the advantages of light weight, high strength, fire energy saving, no radiation, no remarkable features of aging. In contrast, usability and science are in stark contrast to traditional ways.
