Flame retardant curtains are curtains made of flame retardant fabrics, which are widely used because curtain fabrics have flame retardant functions and can achieve fire and disaster reduction effects.
Curtain fire classification
The People's Republic of China standard GB50222-95 "Code for Fire Protection of Interior Decoration Design of Buildings" stipulates that decorative materials are classified into four levels according to their combustion performance: A-level non-combustibility; B1-level non-combustibility; B2-level flammability; B3 flammability. Therefore, only fabrics that reach A and B1 levels can be called flame retardant fabrics. At present, in addition to non-textile fabrics that can achieve Class A flame retardant, the highest grade of flame retardant textile fabrics is B1.
Flame retardant curtains can also be divided into permanent flame retardant curtains, disposable flame retardant curtains and nano flame retardant curtains according to the flame retardant fabric used.
First, permanent flame retardant curtains
It means that the original fabric is made of permanent flame-retardant fabric combined with modern special curtain making technology.
Second, disposable flame retardant curtains
Of course, it is curtains made of disposable flame retardant fabrics. For reasons of cost and technology, disposable flame retardant curtains were more popular earlier, and with the improvement of people's lives and the development of technology, the advent of permanent flame retardant curtains has become more and more popular.
Third, nano flame retardant curtains
It refers to curtain fabrics that use nano materials to process curtain fabrics with nanotechnology to achieve flame retardant, heat insulation, sound insulation, antibacterial, antibacterial, waterproof, oilproof, antifouling, dustproof, and antistatic functions.
Textile combustion test methods vary according to the principle, equipment and purpose. The test results of various test methods are difficult to compare with each other. The experimental results can only explain the pros and cons of the combustion performance of the sample to a certain extent. The combustion test method is mainly used to test the breadth (carbonized area and damage length), afterflame time and flame retardance time of the sample.
According to the relative position of the sample and the flame, it can be divided into vertical method, tilt method and horizontal method. The principle is to place a sample of a certain size vertically in a prescribed combustion test chamber, and ignite it with a prescribed ignition source for 12 seconds. After removing the ignition source, measure the afterflame time and smolder time of the sample. Determine the length of the damage by the specified method. This method can be used to determine the flame retardancy of clothing fabrics, decorative fabrics, and tent fabrics. China's textile flame retardant performance evaluation method is based on the burning rate of the fabric. Only textile products that meet the standard requirements can be regarded as flame retardant products.
China has formulated and implemented more than 10 different test method standards, such as: GB / T5454-1997 "Textile combustion performance test oxygen index method", GB / T5455-1997 "Textile combustion performance test vertical method", GB / TF5456-1997 "Determination of the Flame Propagation Performance of Textiles in the Combustion Performance Test in the Vertical Direction", etc. In China, GB / T5455-1997 "Textile Burning Performance Test Vertical Method" is mainly used for testing the flame retardancy of clothing.
