以氯化物鹽為主的傳統型除冰劑雖然原料廉價易得,冰點低,但融解過程吸熱,對環境造成污染,對道路設施產生腐蝕。Cma, as an alternate deicer, tends to inhibit corrosion and appears to be relatively harmless to the environment. but cma is expensive because of the high price of its material, and it has less ability in melting ice than sodium chloride. besides these, cma sticks to wet surfaces and can congeal to form hard chunks, difficult to store for a long time, dusty and a strong vinegar smell when spread
而cma是對氯化物鹽除冰劑的重大改進, cma具有無污染,環保的特點,對金屬幾乎無腐蝕,但由於原料價格昂貴,使得cma的價格不菲, cma對冰的融化能力不如氯化鈉, cma易結塊,不宜長期儲藏,在撒布時形成的粉塵及刺鼻的酸味亦是需要改進的地方。All of these aspects need to be improved. considering the disadvantages of the two kinds of the deicers, great amounts of the science data are referred in the research experiment, by developing the main materials and the additives, a new kind of deicer : pal is founded. not only does pal remain the advantages of the traditional deicer such as cheap materials and low freezing point : - 43. 8 c, but it has the character of cma, low corrosion to steel and concrete
