TCEP Flame Retardant Phosphoric Acid (Dichloroethyl) Triester Save Life Preserve precious time
Edit: Taizhou New Material Co., Ltd.Date: 2016-07-02

do you know? TCEP Flame Retardant is a functional additive that imparts flammable properties to flammable polymers that can save lives and retain valuable time. Taizhou Xin'an Flame Retardant Material Co., Ltd. Hangzhou Office is a supplier of liquid flame retardants such as polyurethane rigid foam flame retardants. For more information about the flame retardants and TEP prices of TEP manufacturers , please call 0571-87228613


Anyway, look at a set of data:

June 5, 2009, Chengdu, a bus accidental arson case, killing 27 people were killed, 74 people were injured;

July 21, 2010, Changsha airport bus was deliberately arson, 2 people were killed, 3 seriously injured;

June 7, 2013, occurred in Xiamen bus accidental bombing, 47 people die, 34 people were injured;

January 5, 2016, Ningxia bus accident deliberately, 17 people were killed, 32 people were injured;

...

A bus, filled with passengers, and perhaps mixed with ulterior motives of criminals. How long do we need to escape if we set fire? Xiamen bus arson occurred, an accident scene photos were uploaded to the network: many passengers jam at the bus door, and ultimately still fought in the sea of fire. They have tried to escape, but left them too little time, less enough to allow them from the narrow space within the crowded crowded crowd, fled outside the door.


It is understood that the bus seats are generally made of ABS, polypropylene and other plastic, are flammable materials. Where the seats will melt and burn, where the molten material flows, where it is ignited; and the bus for the pursuit of comfort, but also in the seat filled with extremely flammable foam, and in the appearance of the package Flammable fabrics. Once the fire, the fire in a very short period of time can spread around, and then sparked. To the flashover stage, the passengers no escape possible. In other words, from the moment of the fire, to the fire began to spread around this time, that is, people escape time, is to save lives time.


As far as possible to extend the escape time, China is developing a bus on the bus, the new GB requirements in the seat and interior materials to add flame retardants. TCEP flame retardant is a functional additive that imparts flame retardancy to flammable polymers. The flame retardant is added to the raw material to form a flame retardant material. To fire-resistant materials to create seats, car interior, etc., can effectively extend the time from the ignition to the fire, leaving people escape time. Back to the beginning of the article experiment, the audience talked about the "3 minutes", is this valuable escape time.

 

According to reports, it is to verify our country is the development of bus, bus flame retardant standards related requirements, China Fire Services Institute jointly with the Ministry of Public Security Sichuan Fire Research Institute, China FAW Technology Center, planning this together to verify the experiment. In the experiment, the burning of the bus seats, roofs, flooring and other materials are in accordance with the draft national standards of the relevant requirements of manufacturing. So, the interior material after a certain flame retardant processing of the bus, to give passengers in the fire enough to escape or fire time? "Onlookers" of the audience of this experiment are talking about. These professional audiences come from fire agencies, fire-retardant companies, and even bus seat manufacturers, they told reporters that for fewer passengers, the 3-minute time is still enough to escape; but for overcrowding bus , 3 minutes, is still far from enough.


Is the bus to sit still? The answer is of course negative. Ministry of Public Security, Sichuan Institute of Fire, assistant researcher Xie Le Tao led the reporter visited the bus last year, carried out the ignition experiment. It can be seen that the fire only on the fire point seat and next door connected to the seat caused some damage, did not spread to the front and rear seats, but no occurrence of flashover. Xie Le Tao told reporters that the difference in the bus experiment, the Institute of the seat material calorific value and heat release rate are to do stringent requirements, the material to GB 8624 B1 standard (ie, flame retardant materials). With such materials to create seats, fully able to control the fire within a very small range. In the passenger car experiment, the temperature and the heat release rate of the seat foam are not limited. Once the flame retardant fabric attached to the surface is burned out, the foaming of the foam will cause the whole vehicle to fire in a short time.


For flame retardant materials, there are different indicators to evaluate their flame retardant properties: oxygen index, vertical flammability, smoke density, calorific value and heat release value. The heat value and the heat release rate are also important for assessing the fire performance. At present, due to the high demand for testing equipment and technology, most of the criteria for combustibility are not cited in these two indicators. Xie Le Tao said that the current Ministry of Public Security Sichuan Fire Research Institute is to promote the bus interior materials related to the standard revision, called for the gradual increase in calorific value and heat release rate requirements related to the standard. He also said that the control of "double value", for seat manufacturers, in the seat materials, fire-retardant technology and production costs have great challenges.
