"Although the proportion of fire doors in building fire protection is not large, on the whole, the market is very chaotic, and poor quality products flood the market, which brings great hidden dangers to building fire protection." Said the deputy general manager of the fire door manufacturer.
Taking the price as an example, he pointed out that the prices of fire doors on the market vary, and some even double, "It is conceivable that there are fake and shoddy products."
Market chaos
According to reports, a random inspection of fire protection products in Jiangsu Province found that the pass rate of fire doors was only 45.5%, and the pass rate of fire retardant coating application quality was zero. Relevant statistics show that due to product quality, the proportion of building firefighting facilities that cannot be operated normally or put into use is as high as more than 30%. If the fire loss is significant, most of the building firefighting facilities do not play a role when the fire occurs.
The quality of fire doors is particularly worrying. In the inspection of Changzhou City, Jiangsu Province, it was found that the thickness of the fire door steel plates produced by many manufacturers is only half of the standard, the filler material has poor fire resistance, the thickness is not enough, and the quality of the fire board is inferior; Proof of market access for related products, high-priced purchase of samples for inspection, after the certificate is handed, the quality of its own products is still unqualified.
What's more, knowing that the fire door is used to block the fire, refractory materials must be used, but flammable honeycomb paper is used as the filler material of the fire door. Therefore, the fire door used to protect the safety of residents was created. " Fire the door. "
The relevant person in charge of the Fire Bureau of the Ministry of Public Security once told the media that the demand for public fire protection facilities and fire safety products in China has increased dramatically, and the fire industry has shown an unprecedented development momentum. At present, there are more than 10,000 production and service-oriented enterprises in the industry. Thousands of fire protection products.
"However, the order of China's fire protection products market is still chaotic. A large number of inferior fire protection products have flowed into construction projects and fire protection systems, resulting in the use of fire protection facilities, resulting in a large number of hidden fire hazards and severely endangering public safety." The official pointed out.
The new standard will come out
People in the fire protection system reminded that the purchase of fire doors must be approved by companies that have the qualification to produce fire doors.
Fire door manufacturing enterprises must obtain a fire product type approval certificate issued by the Fire Products Conformity Assessment Center of the Ministry of Public Security before they can produce, sell, or install fire doors. An enterprise that has obtained an approved certificate, once the certificate has been suspended or has not been renewed, shall not sell, install and use fire door products until the certificate is restored.
The deputy general manager of the aforementioned fire door manufacturing company said that the new version of the fire door standard will be released, but the new product standard is still in the trial production stage, and the company is waiting.

The meter consists of mass flow sensor and transmitter. Mass flow sensor is a phase-sensitive resonant sensor based on Coriolis effect, composed of vibration tube, signal detector, concussion driver, structural support, shell, etc.
Mass flow transmitter is a micro-programming-centered electronic system, which supplies
thrust to sensor, transforms sensor signal into mass flow signal & others, and improves
accuracy in accordance with temperature parameter.
It`s composed of switching power supplier, guard grating, core processor board, display
module, etc., installed in a ex-proof junction box. Switching power supply offers power for
transmitter; safe grating isolates sensor and transmitter intrinsically; core processor detects
& processes sensor phase signal, sends mass flow signal and process communication.
