防爆纤维简介
防爆纤维是防爆化学纤维的简称,纤维是以聚丙烯为原材料,通过特殊工艺制造而成的,具有抗拉申、耐冲击、提高整体强度;疏水、排气、防龟裂、防爆裂;缩短烘烤周期、简化升温过程,提高整体使用寿命的一种特殊纤维。在定型与不定型耐火材料烘焙干燥过程中,为了便于水蒸气压力从砌体中得到及时释放,防止砌体的爆裂而加入浇注料中的一种用添加剂。
纤维的作用机理在于十分均匀乱向分布在砌体中,形成由内及外,由上至下的网络体系,随着烘焙温度的提高,它开始软化、收缩、熔化, 形成气孔,原有的网络体系变成了类似人体的汗毛排汗体系。将烘焙过程中产生的水气压力及时排出。而关键的纤维与纤维之间的搭桥联接、排气孔径的大小,纤维在砌体中分散程度决定了砌体中排压的效果。
金林防爆纤维有两种:软化点80与110,熔化点100与150。纤维加入耐火材料或建筑混凝土、灌浆料、工业地坪、干粉砂浆肌体中可有效缩短烘干时间,并且防爆纤维可以提高材料的整体抗折与耐压强度等性能,迅速排出水蒸汽降低内应力、防止爆裂、龟裂现象的发生。

防爆纤维性能
金林防爆纤维具有栈积比重小、分散性好、无烧结、无并丝、残留少、使用效果佳等特点,是各种不定型耐火材料新型防爆剂,尤其适用于高强快干不定型耐火材料。
1、抗拉申、耐冲击、提高整体强度。
2、疏水、排气、防龟裂、防爆裂。
3、缩短烘烤周期、简化升温过程,提高整体使用寿命。
防爆纤维使用方法
1、掺量范围:0.6-1.8kg/m3,混凝土抗裂防渗建议掺量0.9kg/m3。
2、长度选择:砂浆建议用6-8mm,混凝土建议用12-19mm。
3、将粗细集料连同纤维一起加入搅拌机加水搅拌,适当延长时间使纤维在混凝土中均匀分散。
防爆纤维用途
1、混凝土刚性自防水结构、地下室底板、侧墙、顶板及屋面楼板、水池等。
2、水泥砂浆、干粉砂浆、保温砂浆、抗裂砂浆、内外墙抹灰砂浆等。
3、抗裂、抗冲击、抗磨损、抗震等要求的场合。
4、桥面、桥墩、港口码头、水利工程等。适用于各种散状材料如涂抹料、浇注料等不定形耐火材料,应用效果尤为显着。
防爆纤维运输储存须知
运输与装卸:在运输过程中,不得用铁钩拖拽,应防止与坚硬物质混装,不可强烈振动、磨擦、踩、砸,严禁抛掷,应轻装轻卸,以减少包装破碎,影响使用。
储存:应储存于阴凉干燥处,防止内外包装袋破裂,防止受潮和吸附空气中其它物质,影响使用效果。严禁与有毒有害气体或易挥发物质混放,存放要远离污染源。

Explosion-proof fiber profile
Explosion-proof fiber is short for explosion-proof chemical fiber, riot fiber based on polypropylene as raw material, made by a special process, with tensile, impact resistance, enhance the overall strength; Hydrophobic, exhaust, against chapping, the blowout; Shorten the baking cycle, simplify the process of temperature, improve the overall service life of a kind of special fibers. In shape and not stereotypes refractories for drying process, in order to facilitate water vapor pressure from masonry timely release, prevent masonry burst and join a special additive of castable.
Riot fiber mechanism is very uniform random distribution in masonry, formed by inside and outside, top-down network system, with the improvement of baking temperature, it begins to soften, shrinkage, melting, finally formation porosity, the original network system into a system similar to human hair perspiration. Water vapour pressure generated in the roasting process in time. And key bridge between the fibre and fibre connection, exhaust aperture, the size of the fiber dispersion degree determines the masonry in the masonry out the effect of pressure.
Explosion-proof fiber has two kinds: softening point 80 and 110 , melting point 100 and 150 . Fiber in refractory material or construction concrete, grouting materials, industrial floor, dry mortar can effectively shorten the drying time in the body, and explosion-proof fiber can improve the overall flexural and compressive strength of materials, such as performance, fast discharge steam to reduce internal stress, prevent the occurrence of burst and cracking phenomenon.
Explosion-proof fiber performance
Jin Lin explosion-proof fiber has the mass density is small, good dispersibility, sintering, and silk, less residue, use effect is good wait for a characteristic, is all sorts of new explosion-proof agent not stereotypes refractories, especially suitable for high strength fast dry not stereotypes refractories.
1. Tensile shen, impact resistance, increase the overall strength.
2. The hydrophobic, exhaust, against chapping, the blowout.
3. Shorten curing cycle, simplify the process of temperature, improve the service life of the whole.
