Testile Testing Equipment

In general, the combustion is divided into flame burning and flameless combustion, the former is the formation of fiber pyrolysis of the gas or volatile liquid combustion, the latter is the residue (carbon) oxidation. Of course, the combustion of the fiber is related to the product of its thermal cracking, and the thermal cracking process of the different fibers is different. The following are the same as the " Flame retardant test instrument mechanism (1) cover theory: flame retardant at> 500 ℃ in the fiber surface can form a protective layer of the cover, in addition to hinder the supply of O2, but also to prevent the proliferation of combustible gas, so as to achieve flame retardant purposes, such as borax - boric acid The (2) gas theory: First, the flame retardant at the combustion temperature, decomposition of non-combustible gas, the flammable gas concentration can be produced to produce the flame concentration below; the other is the flame retardant in the...

1 Scope :Textiles Combustion Performance Test Vertical Method This standard specifies the test method for the determination of the flame retardancy of various flame-retardant textiles for the purpose of determining the tendency of textiles to continue burning, smoldering and carbonizing. This standard applies to the determination of flame retardant fabrics, knitted fabrics, coated products, laminated products such as flame retardant properties.   2, reference standard: The following standards contain provisions which, by reference in this standard, constitute provisions of this standard. At the time of publication of this standard, the versions shown are valid. All standards will be revised and the parties using this standard should explore the possibility of using the latest version of the following standards. GB 6529-86 Standard atmosphere for humidity control and testing of textiles   3, textiles combustion performance test vertical method definition This standard ...
