無水氯化鈣可用作多用途的乾燥劑脫水劑，如用於氮氣氧氣氫氣氯化氫二氧化硫等氣體的乾燥，在生產醇酯醚和丙烯樹脂時用作脫水劑。For concrete structure in the practical engineering, the non - mechanics damages, such as alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw, and so on, are unavoidable due to the exist of erosive media. the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly, and shortens the service life of the concrete to a large extent. permeability of concrete is the most important factor for these non - mechanics damages, so the permeability test of concrete is the normal and required item to study the durability of concrete
實際工程中的混凝土結構，因侵蝕性介質的存在而使非力學破壞行為無處不在，這些非力學破壞行為包括堿集料反應、硫酸鹽侵蝕、碳化、鋼筋銹蝕、凍融等，單一的破壞形式或多形式的復合破壞作用對混凝土結構性能及耐久性能均有著較為嚴重的影響，在很大程度上縮短了建築物的服役年限，而這些非力學破壞在很大程度上取決于其滲透性，所以測試混凝土滲透性能是研究判斷混凝土耐久性的常規必測項目。Compared with other flame retardants, it has better function on restraining of the producing of smoke and sulfureted hydrogen, with the advantage of no contaminate, no corrosion and low cost
氫氧化鎂屬于添加型無機阻燃劑，與同類無機阻燃劑相比，具有更好的抑制發煙和硫化氧生成的作用，且無毒害、無腐蝕、價格低廉。Sns has an energy gap of eg 1. 3ev, which is very close to the optimum energy gap 1. 5ev of solar cells, and it has a high absorption coefficient ( > 104cm - 1 ) and a high conversion efficiency of about 25 %. in addition, elements sn and s are abundant and non - toxic in nature
