Description
Technical field
The present invention relates to a kind of method of testing of gas release performance, the method for testing of harmful gas release performance when particularly relating to a kind of textile combustion.
Background technology
At present, the domestic indexs such as lasting serviceability temperature, maximum operation (service) temperature, carburizing temperature and oxygen limit index of when estimating the fire resistance of textile, mainly considering fiber, and the gas property that the fabric burning produces also is another important indicator of estimating its flame-retardant nature.Ecological textile helps Environmental Safety and health.
The test method that harmful gas discharges during existing material combustion is respectively: domestic " material at high temperature decomposition gas oxicity analysis " (TB/T2946-1999), France " burning test. the analysis of waste gas. part 1: thermal degradation produces the analytical approach two of gas " (NF X70-100-1-2001) etc., the burning performance evaluation project of Japanese textile has also comprised the burning gas project.Existing external fabric burning gas method of testing (shown in Figure 1), the basic principle of work of this method of testing is: by resistance wire 21
Sample is carried out heating flame, and gas collector 23 is collected sample 20 burnings and is produced gas, and measures by 22 pairs of gases of detector.This operative configuration is simpler, but test event is comparatively single, and can only sampling burn under anaerobic environment, and the environmental parameter of many burning gases, all can not test as the humiture of gas, the required oxygen amount of burning etc.
Along with increasingly stringent, be to have relatively high expectations in the control of the burning gas component that all its burning produced of ecological textile or flame retardant textiles and content to environmental requirement.The country that some are economically developed and environmental requirement is strict, when the flame-retarding characteristic of estimating textile and environmental requirement, often introduce burning and produce this index of harmful gas, and China's method of testing does not in this respect also form, need test by external mechanism for testing toward contact during the test fabric burning gases, be badly in need of a kind of method of testing now, textile to China detects and evaluates, to improve the competitive power of the high-grade textile of China's high-performance.
Summary of the invention
The method of testing of toxicity gas release performance when technical matters to be solved by this invention provides a kind of textile combustion to remedy the deficiency and the defective of existing method of testing, satisfies the environmental requirement of textile.
For achieving the above object, technical scheme of the present invention is as follows:

(2) temperature in the mensuration furnace chamber
Show temperature in the furnace chamber that thermocouple 5 measures with digital display adjusting apparatus 10, and the probe of flue gas analyzer 6 is placed the test port of test section;
(3) the harmful gas composition and the concentration of test textile samples
Under different temperature conditions, test harmful gas composition and the concentration situation that the textile samples high-temperature oxydation produces under this temperature by flue gas analyzer.
In above-mentioned second step, used flue gas analyzer 6 is quick flue gas analyzer; Used digital display adjusting apparatus 10 is the thermostatic control adjusting apparatus.
The beneficial effect of method of testing of the present invention is: reasonably adopted novel test instrument and new assembled scheme, can test harmful gas composition and concentration that textile combustion produces in the short period of time, testable harmful gas composition comprises CO
2, CO, SO
2, H
