powder fire branch

As is known, one of the most useful fire suppression agents, the traditional dry powder has been applied in portable fire extinguishers for years.

实验结果表明,与普通干粉相比,经改性细化的粉体的灭火时间缩短了1/2,灭火性能显著提高。

Composed of dry powder,insulating board,alkali-resistant glass fabric and finishing layer,it is a new type of wall insulation structure that has the functions of insulation and decoration,and has the advantages of easy construction,light self-weight,good crack resistance,insulation and energy-saving,good safety and long durability and etc.

它是由干粉、保温板、耐碱玻纤网格布和饰面层组成的集墙体保温和装饰功能于一体的新型墙体外保温构造系统,具有施工方便、自重轻、抗裂优良、保温节能、安全耐久等优点,但同时也有干粉料价格较高、材料易粉化、板间易开裂等缺点。

Mordenite with high silica-alumina ratio was first prepared by dry powder method at Na2O-SiO2-Al2O3-NaCl system with satisfactory efficiency.

首次采用干粉法在Na2O-SiO2-Al2O3-NaCl体系中合成出高硅/铝比丝光沸石。

dry powder method and wet gel method invited by our study group) in the synthesis of zeolites is introduced, and the essence and characteristics of the technology processes of two novel methods are interpreted; at last, the prospect of its applications is overviewed.
