congeal time 中文意思是什麼
congeal time
解釋
凍結時間-
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。
