Address: Taian Ning Yang ciyao Town House before the first West Main Street Contact: Mr. Zheng 13562833788 QQ: 819162336 flame retardants are flame retardant through a number of mechanisms to play their role, such as the endothermic effect, overriding inhibit chain reaction, suffocation and other non-flammable gas. Most flame retardant aim is to achieve joint action through a number of mechanisms. 1, any calorie burn in a short time evolved endothermic effect is limited, if they can absorb some of the heat from fire evolved in a short time, then the flame temperature is lowered, the radiation acting on the combustion surface The heat of vaporization of the combustible elements have been cleaved into radicals will be reduced, the combustion reaction will be a certain degree of inhibition. At high temperature, flame retardant strong endothermic reaction occurs to absorb some of the heat released by combustion, to reduce the temperature of the surface of the fuel, to effectively inhibit the formation of combustible gases, preventing the spread of burning. Al (OH) 3 flame retardant mechanism is by increasing the heat capacity of the polymer to the thermal decomposition temperature before reaching absorb more heat, thus increasing its flame retardant properties. Such flame full of a lot of heat when it is combined with steam feature, the ability to improve their own flame. 2, covering the role of combustible materials after adding flame retardant, flame retardants at high temperatures to form a glassy or stable foam blanket, cut off oxygen, with insulation, oxygen barrier to prevent the escape of flammable gas outward action, so as to achieve the purpose of flame. To produce a crosslinked structure more stable solid matter or carbide layer such as an organic phosphorus flame retardant heat. Carbide layer is formed on the one hand can prevent further polymer pyrolysis, on the other hand can prevent the thermal decomposition of material into the interior of the combustion process involved in the gas phase. 3, inhibition of chain reaction chain reaction according to the theory of combustion, is required to maintain combustion radicals. Flame retardants may act in the vapor phase combustion zone, the combustion reaction in the capture of free radicals, thereby preventing the spread of flame, the flame combustion zone density decreases, and finally to the combustion reaction rate decreases until terminated. Such as halogen-containing flame retardants, its evaporation temperature and the decomposition temperature of the same or similar polymer when the polymer is decomposed by heat, flame retardants also evaporate. In this case the halogen-containing flame retardants and thermal decomposition products simultaneously in the gas phase combustion zone, halogen will be able to capture the combustion reaction of free radicals, thereby preventing the spread of flame, the flame combustion zone density decreases, and finally to the combustion reaction rate decreases until termination . 4, non-flammable gas suffocation thermal decomposition of the non-combustible gas flame, the concentration of the combustible decomposition of the combustible gases dilute the flammable limit or less. But also on the oxygen concentration in the combustion zone having a dilution effect, prevent the burning continued to achieve flame retardant effect. Mechanism of combustion and combustion and flame retardant mechanism 5 at 3 and Table 3 and Table 4, we discussed the decision to the burning behavior of textile fibers inherent basic thermal parameters. In order to understand how it works existing textile fire retardant and more importantly - how to develop the future of flame retardants, the key is more in-depth exploration of the combustion mechanism of a fiber-forming polymer. Retardant textile policy Figure 5.1 combustion mechanism (as a feedback mechanism) in the process of FIG. 7, in this combustion, the fuel (from thermal degradation or pyrolysis fiber), heat (from the ignition and combustion) and oxygen (from air) are to play a role as a main component. To interrupt this mechanism, it proposed five ways (a) ~ (e). Flame retardants may play a role in the case where one or more ways. Listed below are the various stages and associated flame retardant effect: a) removing heat; b) increase the decomposition temperature; c) reduce the formation of combustible volatiles, increasing amount of carbon; d) reduction of the contact with oxygen or a dilute flame; e) interference flame chemical reactions and / or increasing the fuel ignition temperature (Tc); melting and / or degradation and / or dehydration need to absorb a lot of heat (for example, a formulation containing inorganic and organic phosphorus in the back coating, aluminum hydroxide or water alumina). Not normally used by a flame retardant; and more common in the natural refractory and heat-resistant fiber (such as aramid fiber) in. Most cellulose and wool phosphorus, nitrogen-containing flame retardant; in wool heavy metal complexes. Hydrated and promote charcoal flame can release some water; halogen-containing flame retardants can release hydrogen halide. Halogen-containing flame retardants, often combined with antimony oxide. As can be seen from the above, some flame retardants can play a role in a variety of ways, most effective examples are true. In addition, some formulations can produce a liquid phase fire retardant intermediate, which intermediate wettable fiber surface, thus becoming heat barrier and oxygen barrier - is widely accepted borate - boric acid mixture in this manner can be play. In addition, it can also promote charring. To simplify the classification of different chemical flame acts the way, you can use the term 'cohesion' phase and 'gas or vapor' phase of activities to distinguish them. Both are complex items, including the above-described former (a ~ c) mode, which comprises (d) and (e) mode. Typically physical mechanism operate simultaneously, these mechanisms include coatings formed by exclusion of oxygen and / or heat (mode d), increasing the heat capacity (mode a) and the use of non-flammable gas or covering flame dilution (Mode d). 5.2 Can thermoplastic fibers soften and / or melt (as defined in Table 3 physical transition temperature) determines whether it is thermoplastic. Thermoplastic its associated physical changes, can seriously affect the behavior of a flame retardant. Conventional thermoplastic fibers (e.g., polyamide, polyester and polypropylene) to leave a contraction ignite the flame, thus avoiding lit: making them on the surface exhibit flame retardancy. In fact, if the contraction is blocked, they will Meng intense burning. This so-called cradle effect in polyester - cotton and blended fabrics like to see that the molten polymer melt to the non-thermoplastic and ignited cotton. Similar effects can also be seen on the composite textile made of thermoplastic and non-thermoplastic component composition. With effect from the above-mentioned droplet (usually flaming droplets) problem, although this dripping hot flame front can be removed and cause the flame goes out (which can 'through' vertical flame test), but it can so that at its lower surface (such as carpet or skin) or secondary ignition combustion occurs. During most of the mass or as a finishing agent is applied to the conventional flame retardant synthetic fibers are usually melt dripping through enhanced and / or pro help extinguish flaming droplets are two ways to play a role. So far, any means can not reduce a large number of thermoplastic and promote charring, the fire-retardant treated cellulose (including rayon fiber) is the case. 5.3 charring flame retardant mechanism and by (d) and / or (e) the way to work in the gas phase flame retardants have the advantage that they can be reduced ignition proclivity and help textile fiber-forming polymeric the flame was extinguished. This is because once the thermal degradation of the volatile product or fuel oxidation reaction with oxygen in the flame, which will become very similar chemical properties. Thus, like the cut off oxygen ((e) mode), or to generate interference radical ((f) mode) these two methods can undoubtedly ensure the flame retardant effect. Based on costs and benefits, antimony - halogen flame retardant polymer within the body and the back coating textiles most successful flame retardant. Durable fiber-reactive flame retardant for cellulosic fibers containing phosphorus and nitrogen are different (see below), they are usually only with a resin binder for the back coating agent. On textiles, the majority of antimony - antimony trioxide and halogen system by bromine-containing organic molecules (such as decabromodiphenyl oxide (DBDPO) or hexabromo tridecane (HBCD)) components. Upon heating, these substances will release HBr base and Br. Group. Both of which can interfere with the chemical reaction of the flame according to the following diagram. In the diagram: R, CH2, H and OH groups are part of the flame oxidation chain reaction, which consumes fuel (RCH3) and oxygen.
