Idle such as vinegar, can soften the spirit of calcium; hard like a torch to ignite the flame of wisdom.
闲散如酸醋，会软化精神的钙质；勤奋像火炬，能燃起智慧的火焰。
So, polystyrene foamed plastic and polyurethane hard foam to the flame retardant function to ensure the whole system how much the fire prevention safety?
那么，聚苯乙烯泡沫塑料和聚氨酯硬质泡沫材料的阻燃机能达到何等程度才能保证整个体系的防火安全？
Whether to need in the existing technology premise too much progress polystyrene foamed plastic and polyurethane hard foam flame retardancy index?
是否需要在现有的技术前提下过多地进步聚苯乙烯泡沫塑料和聚氨酯硬质泡沫的阻燃性指标？
Dacron polyester fibers have a high resistance to burning. They tend to fuse and shrink away from the flame, forming a bead that is very hard after cooling.
大可纶纤维具有较好的阻燃性能。在点燃聚酯纤维时，纤维会熔化并在火焰作用下收缩，最终形成球状。冷却后熔球具有较高的硬度。
Also, no flame burning polyamide fiber. soak up quickly, melting into colloidal material, after cooling of the tough hard ball into brown, not easily broken, faint celery research smell.
锦纶燃烧时也无火焰，纤维迅速卷缩，熔融成胶状物，冷却后成坚韧的褐色硬球，不易研碎，有淡淡的芹菜气味。
The results indicated, plywood with this method is not satisfying and its properties of environmental protection and flame retardation are hard to improve, the highest OI is only 38% in experiments.
试验结果表明，经浸渍处理的成品胶合板的环保、阻燃性能均不理想，很难达到环保、阻燃的要求，试验中氧指数最高为38%。
