  XPS挤出板具有热阻高、线性度低、膨胀比低等特点。所形成的真空层能够保证保温性能的稳定,是一种优质的建筑保温材料。你知道挤塑薄板阻燃剂是如何实现的吗?
XPS Extrusion board has the characteristics of high thermal resistance, low linearity and low expansion ratio. The vacuum layer formed can ensure the stability of thermal insulation performance and is a high quality building thermal insulation material. Do you know how extruded sheet flame retardants are realized?
挤塑板材阻燃是如何实现的
How to Realize Flame Retardant of Extruded Sheet
六溴环十二烷是一种有效的阻燃剂,但传统的六溴环十二烷易分解。根据国内外挤塑板制造商的经验,挤塑板必须使用热稳定的六溴环十二烷,阻燃剂的分解释放出强烈的腐蚀性气体,溴化氢严重腐蚀设备,使挤塑板的阻燃性与溴化氢波动逐渐衰变,但它也是分解温度越高,越好,以匹配和晒版,国内设备常用的阻燃分解温度为240℃较为合适。
Hexabromocyclododecane is an effective flame retardant, but traditional hexabromocyclododecane is easy to decompose. According to the experience of Extrusion board manufacturers at home and abroad, Extrusion board must use heat-stable hexabromocyclododecane, the decomposition of flame retardant releases strong corrosive gas, and hydrogen bromide corrodes equipment seriously, which makes the flame retardancy and hydrogen bromide fluctuation of Extrusion board decay gradually, but it is also the higher the decomposition temperature, the better, in order to match and sun plate, domestic equipment. The commonly used flame retardant decomposition temperature is 240 C.

阻燃色母粒挤塑板阻燃塑料载体,分散剂后挤压机加热颗粒、阻燃剂化合物将占40% - 50%,色母粒的良好分散,使用卫生,没有灰尘,但是缺点是使用成本高,阻燃热加工后不可避免的会有一定的损失,如果不耐热的色母粒阻燃剂的选择普通的六溴环十二烷,分解失效也存在,设备腐蚀问题。

Flame-retardant Color Masterbatch extruding board flame-retardant plastic carrier, after dispersant extruder heating particles, flame retardant compounds will account for 40% - 50%, good dispersion of color masterbatch, sanitary use, no dust, but the shortcoming is that the use cost is high, flame retardant hot processing will inevitably have certain losses, if not heat-resistant Color Masterbatch flame retardant choice is general. Hexabromocyclododecane has decomposition failure and equipment corrosion problems.
粉阻燃使用早期,也广泛使用,其优点是好的经济,阻燃效果好,缺点是塑料粒子的比例不同,容易分层,粉阻燃剂在使用混合设备的选择上,应注意避免沉降分层的出现。此外,阻燃剂必须选用稳定性好的阻燃剂,国内生产的六溴环十二烷必须经树脂表面涂覆处理后才能直接使用
Powder flame retardant is widely used in the early stage of use. Its advantages are good economy and good flame retardant effect. The disadvantages are that the proportion of plastic particles is different and easy to stratify. In the choice of mixing equipment, attention should be paid to avoid the occurrence of sedimentation stratification. In addition, flame retardants must be selected with good stability, and hexabromocyclododecane produced domestically must be coated with resin before it can be used directly.
