Which brand is better for fireproof glass inspection furnaces?

The fire resistant glass inspection furnace is a device used to test the fire resistance performance of fire resistant glass produced by glass deep processing enterprises.Qualified fire resistant glass must have fire resistance performance that meets national standards in order to be processed into products such as fire resistant glass doors,fire resistant windows,fire resistant glass partitions,smoke blocking vertical walls,etc.,and applied to the construction of fire resistant zones in large public places,commercial places,civil buildings,and other areas.

Luoyang Jieman Intelligent Technology Co.,Ltd.,a subsidiary of Gangxin,has deep experience in the research and development of fireproof glass inspection furnaces and customized production,providing customized optimization design solutions for domestic medium and large glass deep processing enterprises.

The fireproof glass inspection furnace developed by Jieman in Luoyang meets the requirements of EN1363-11363-2 curve and ISO 834 standard for fire resistance performance testing of building material components.The temperature tested by this furnace is as high as 1250℃.Our company's temperature rise curve fully meets the temperature rise curve of GB15763.1-2001"Safety Glass and Fireproof Glass for Building Use",that is,the temperature inside the test furnace changes over time,and its variation law meets the following functional relationship:

T-T0=345lg(8t+1)

In the formula:T-average furnace temperature at the time of heating up to t

T0-initial temperature in the furnace,which should be within the range of 5℃-40℃.t-time experienced during the test,min.

As a customized manufacturer of fireproof glass inspection furnaces with a strong R&D team and profound industry background,Luoyang Jieman's customized and developed inspection furnaces can inspect single piece fireproof glass(Class C),composite insulated fireproof glass(Class A),and fireproof windows.Taking the 1.5mx2.5m inspection furnace as an example,the relevant technology needs to meet the following conditions to better ensure the accuracy and professionalism of the inspection results.

1.Equipment cavity size:2.1 meters(width)×1.7 meters(height)×0.8 meters(deep),determined according to the final design.

2.Maximum test glass size:1.2 meters×0.7 meters.

3.The furnace covers an area of 1.8 meters(height)*1 meter(width)*4 meters(depth).

4.Burner power and quantity:230KW,2 pieces.

5.Overall power:AC380V,15Kw.

6.Fuel and gas consumption:liquefied gas,consuming 15 kilograms of liquefied gas per hour(depending on the size of the burned glass).

7.Thermocouple measurement:A total of 3 thermocouples,1 for each wall in the furnace and 1 for the back.

8.Temperature control method:combustion proportional combustion,automatic temperature adjustment,temperature controlled by national standard curve PID,fully automatic PLC temperature control mode.

9.Negative pressure control in the furnace:The pressure transmitter and induced draft fan frequency conversion program are used to automatically adjust the negative pressure in the furnace.

10.Ignition method:Fully automatic high-voltage electronic igniter ignition.

11.Explosion prevention measures

(1)Explosion proof measure 1:Before ignition,the combustion fan automatically blows for 3 minutes,and the remaining gas in the furnace is blown clean with air.The ignition can only be started after the blowing is completed.

(2)Explosion proof measure 2:The ignition controller has a high pressure ignition duration of 7 seconds,and monitors the flame signal in real-time.Once the ignition is unsuccessful,the gas supply solenoid valve will be automatically cut off and the gas supply will be stopped.If the flame extinguishes during the combustion inspection process,the gas supply solenoid valve will be cut off within 1-2 seconds to prevent insufficient combustion gas in the furnace

(3)Explosion proof measure 3:The gas supply main is equipped with a manual shut-off valve,pressure reducing valve,high and low pressure protection switch,safety shut-off main solenoid valve,safety ball valve,and pressure gauge.

(4)Explosion proof measure 4:Install a flame arrester(one-way valve)on the gas supply pipeline to prevent backfire and explosion

(5)Explosion-proof measure 5:First carry out low-power ignition,and after all ignition is successful,it will turn into a large fire.

12.Observation ports:2.

13.Printing system:includes an A4 printer that can print data in real-time.

With the increasing demand for the quality of fireproof glass in the green building fire protection design market,in order to ensure product quality and prevent irreparable economic losses,configuring a fireproof glass inspection furnace will become a standard configuration in the industry.However,practice has proven that the fire resistant glass inspection furnace is different from ordinary glass deep processing equipment,and most of them need to be tailored to a specific background in order to better empower the development of fire resistant glass production enterprises.
