翻譯如下段落：

鹵素的阻燃機理與無鹵的阻燃機理不一（黑色為含鹵素的聚氯乙烯，藍(lán)色為無鹵的聚烯烴）
   含鹵素的材料，由于受熱時會發(fā)生分解，釋放出鹵化氫，鹵化氫能捕捉活性的自由基HO，從而能減緩和終止燃燒鏈鎖氧化反應(yīng)，達(dá)到阻燃目的。此外鹵化氫氣體是難燃性的氣體，它們的比重比空氣重，能排代空氣，形成保護(hù)層，起隔絕氧氣的作用，從而使燃燒延緩或熄滅，聚氯乙烯樹脂中含氯量達(dá)56.8％，樹脂的氧指數(shù)更是高達(dá)42，其本身的難燃性就較好，為自熄性聚合物。
   無鹵的阻燃聚烯烴材料是選用聚烯烴作為基礎(chǔ)聚合物，其基料氧指數(shù)為18，為易燃物，添加大量的Al(OH)3或Mg(OH)2而組成。聚烯烴系純碳?xì)浠衔�，極易燃燒，燃燒時分解成水和二氧化碳，不產(chǎn)生明顯的煙霧和有毒的腐蝕性氣體。Al(OH)3或Mg(OH)2受熱后會釋放結(jié)晶水，吸收大量熱量，從而抑制聚合物溫度上升，延緩熱分解，阻止燃燒。此外，脫水分解所產(chǎn)生的水蒸氣也能稀釋可燃性的氣體，從而起到阻燃效果。

Halogen-free flame retardant halogen-free flame retardant mechanism and the mechanism of mixed (black halogen containing PVC, blue for non-halogen polyolefin)
    Halogen containing materials, will happen because of the heat decomposition, releases hydrogen halide, hydrogen halide to capture the activity of free radicals HO, so that it can slow down and termination of chain combustion oxidation reaction to reach the purpose of fire-retardant. In addition halogenated flame retardant are precursors of hydrogen gas, which is heavier than air, the proportion can be scheduled on behalf of the air, the formation of protective layer, isolated from the role of oxygen, thus delaying or burning off, the chlorine content of PVC resin reached 56.8 % resin oxygen index is as high as 42, the Flame of its own on the better for the self-extinguishing polymer.
    Halogen-free flame retardant polyolefin material is selected as the basis of polyolefin polymers, its oxygen index for the base material 18, as the combustible, add a large number of Al (OH) 3 or Mg (OH) 2 formed. Department of pure polyolefin hydrocarbons, easily burning, burning when broken down into water and carbon dioxide, does not produce obvious toxic smoke and corrosive gases. Al (OH) 3 or Mg (OH) 2 after heating to release crystal water, absorb substantial heat, thus inhibiting polymer temperature rise, retard thermal decomposition, to prevent burning. In addition, the dehydration produced by decomposition of water vapor can also dilute the flammable gases, which play a fire-retardant effect.

    The flame retardant mechanism of halogen ang halogen-free is different(Black as the polyvinyl chloride containing halogen, blue is the halogen-free polyolefin)
  

     Because of the materials containing halogen will decompose , release hydrogen halide,and halogenating  hydrogen can capture the activity of free radicals HO  when heated.Thus can slow down and terminate the oxidation reaction of combustion chains to achieve the purpose of flame retardant.Besides the gaseous halogenating hydrogen  is Flame retardant gas ,and it's heavier than air so that it is able to exhaust and replace the air and form protective layer which can isolated from the  oxygen.Thus burning delay or extinguished.The chlorine that PVC resin content  reached 56.8 % ,and the resin oxygen index is as high as 42.
It is the self-extinguishing   polymer for the flame retardant itself is good .
  

      Halogen-free flame retardant polyolefin materials choise the polymers  based on  polyolefin. Its oxygen index for the base material which  is combustible and add a large number of  Al (OH) 3 or Mg (OH) 2 reach to 18. Polyolefin is pure hydrocarbons can be easily burning.They decompose into water and carbon dioxide, no obvious smoke and poisonous corrosive gas when burning.Al (OH) 3 or Mg (OH) 2 release crystal water and absorb substantial heat after heating .Thus restrain polymer temperature rise, retard pyrolysis, and prevent burning. In addition, the water vapor produced by dehydration decomposition can also dilute the flammable gases, which play the effect of flame retardant .

一時手癢，加上缺錢，所以也來試試。字句次序有改動以適應(yīng)英語的習(xí)慣語氣。

Although both halogen and halogen-free materials can be fire retardant, the mechanisms are different. (PVC with halogen content is black in color while halogen-free Polyolefin is blue)

The material containing Halogen can release Hydrogen Halide when heated. Hydrogen Halide absorbs free HO, which slows down or even terminates the chain reaction of oxidation (combustion). In addition, since Hydrogen Halide is non-flammable and heavier than air, it stays below the air and isolates the oxygen from the burning object when released. Thus the fire is confined and then extinguished. In the particular case of PVC resin, the high Chlorine content (52.8%) and oxygen index (42) also contribute to its superior non-flammable property. It is so called self-extinguishable polymer material.

On the other hand, halogen-free material comprises of base material Polyolefin and a large amount of Al(OH)3 or Mg(OH)2. Polyolefin itself is pure hydro-carbon with oxygen index of 18.  It is extremely flammable and decomposes into water and CO2 when burnt, without producing visible smog or corrosive poisonous gas. Al(OH)3 or Mg(OH)2 releases water vapors as well when its crystalline framework destructed by heat. However, the vaporization of the water then absorbs significant amount of heat so that effectively stopped further material destruction and therefore extinguish the fire. Besides, water vapor itself dilutes the flammable gas and further enhances the fire retardant effect.

The halogen being flame-resistant mechanism varies (black with the non-halogen's being flame-resistant mechanism to contain halogen polyvinyl-chloride, blue color for non-halogen polyolefine) Including halogen material, because is heated time will have the decomposition, will release the haolgen hydride, the haolgen hydride can catch active free radical HO, can thus slow down and terminate the combustion chain oxidizing reaction, will serve the being flame-resistant purpose. In addition the haolgen hydride gas is the flame retardancy gas, their proportion is heavier than the air, can displace the air, forms the protector, plays the isolation oxygen the role, thus causes the combustion to delay or the extinguishment, in the polyvinyl chloride the chlorinity reaches 56.8%, the resin oxygen index is reaches as high as 42, its flame retardancy is good, for from extinguishes the polymer. The non-halogen's being flame-resistant polyolefine material selects the polyolefine underlie polymer, its parent metal oxygen index is 18, is the combustible, increases massive Al(OH)3 or Mg(OH)2 composes. The polyolefine is the pure hydrocarbon, is extremely inflammable, when combustion decomposes into Cheng Shui and the carbon dioxide, does not produce the obvious smog and the virulent caustic gas. After Al(OH)3 or Mg(OH)2 heating, will release the crystal water, the absorption massive quantity of heats, will thus suppress the polymer temperature rise, will delay the thermal decomposition, the impediment combustion. In addition, the dehydration decomposes the steam which produces also to be able to dilute the ignitable gas, thus has the being flame-resistant effect.
