Acceptable quality PVC floor fire up to B1 grade PVC membrane indicators, B1 level ie fire performance is excellent, second only to the stone. PVC floor itself does not burn and can prevent burning; no cause interest of toxic gases (according to figures provided by the security sector: 95% of people in the fire that hurt toxic fumes and gases during combustion actions). PVC floor surface wear layer has a special slip resistance, and compared with the general ICU purify ground material, PVC flooring in the sticky situation of water foot feeling more astringent, less likely to slide, that the more water the more astringent. As a result, it is common in the higher security requirements in public places such as airports, hospitals, kindergartens, schools, etc. is the preferred surface decoration materials, in recent years has been very popular in China. PVC flooring is vinyl resin as the main ingredient, and no affinity for water, so its natural fear of water, if not long-term immersion will not be damaged; and not because of the humidity and mildew. Installed in the central air-conditioning duct system, the working principle is easy to control the temperature of fusion of gold, the use of gravity acting and spring mechanism to close the valve. When a fire occurs, the flame duct invasion ICU purification cantilever crane tower, high temperature melting fusible alloy valves, or to make memory alloy deformed the valve automatically closes for the duct and the fire district throughout the occasion. Installed in the ventilation, air conditioning system, the return air duct purification ICU road electric sliding doors, usually was turned on when the gas pipeline fire when the temperature reaches 70 ℃, fusible film fuse, the valve automatically closes in the torsion spring force within a certain period of time to meet the fire resistance stability and fire integrity requirements, from smoke fire retardant effect of the valve. When the valve is closed, the output signal is turned off. ICU purification sliding doors _ purification color plate (certified) _ICU purification by Hebei Medical Engineering Co., Ericsson.
