 塑料在使用过程中为防止塑料由于接触火焰着火而使用阻燃剂,是为了保证塑料能有更长的使用寿命,适当地增加使用塑料的安全保障。一般来讲,高聚物阻燃技术主要分为添加型与反应型两种方式,而在所谓的”塑料”概念下,主要是以添加型为主。即在普通粒料中添加与之匹配的阻燃剂,在搅拌机内充分混合,然后进入以双螺杆挤出机为主的混炼装置重新造粒,制备出阻燃改性的“阻燃塑料”。
The purpose of using flame retardant to prevent plastics from touching flame is to ensure that plastics can have longer service life and increase the safety of using plastics appropriately. Generally speaking, polymer flame retardant technology is mainly divided into two types: additive and reactive, and in the so-called "plastics" concept, mainly additive-based. The flame retardant plastics were prepared by adding a matching flame retardant into the common granule, mixing it fully in the mixer, and then re-granulating in the mixing device with twin-screw extruder as the main part.
塑料为什么要添加无卤环保阻燃剂
Why should plastics be added with halogen-free environmentally friendly flame retardants?
在大部分场合里塑料聚合物会引起或者传播火焰,因为它们都是有机化合物塑料,当受到热的时候,能分解成不稳定的易燃的产物,然而,在许多优先域里,如电力、电子、运输、建筑等等,无论使用塑料聚合物会带来的优点有多么的重要,它使用是受到其自身可燃性的限制的,目前合成聚合物的推广使用已经大大地增加了“火险”和“火灾”发生的可能性,这个危险和身处于建筑物之中的每一个人息息相关。
In most cases, plastic polymers cause or spread flames because they are organic compound plastics that break down into unstable, flammable products when heated. However, in many areas, such as electricity, electronics, transportation, construction, etc., regardless of the advantages of using plastic polymers How important is it that its use is limited by its own flammability, and the current use of synthetic polymers has greatly increased the likelihood of "fire" and "fire" occurring, which is closely related to everyone in the building.
如果想达到法定的防火要求,必须在塑料聚合物里添加阻燃剂,这些添加剂的主要作用有以下几点:减缓聚合物燃烧或者分解的时间; 减少放出烟;避免产生熔滴。为了增加人们的逃生时间,严格的标准将建立以提供足够的需要逃离一个环境的时间。
If you want to meet the statutory fire protection requirements, you must add flame retardants to the plastic polymer, these additives have the following main role: slow down the burning or decomposition of the polymer time; reduce the emission of smoke; avoid the generation of droplets. In order to increase people's escape time, strict standards will be established to provide enough time to escape an environment.
