deicer n.(機翼上的)除冰裝置。

deicide

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 針對上述除冰劑的缺點,本課題收集了國內外大量的相關科技文獻,通過對主體物料和添加劑兩方面的改善,尋找到一種新型除冰劑pal ,它既保留了傳統除冰劑的優點,原料廉價易得,低冰點,可達- 43 . 8 ;又兼有cma的優點,對鋼鐵幾乎無腐蝕,對混凝土無不良影響。

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,但由于原料價格昂貴,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。

Abstract : the paper analyses and compares the current test methods of deicer - frost in different countries . on the basis of the study of influence on deicer - frost scaling of concrete , the test method of deicer - frost was further improved , and an easier preparing method of samples for deicer - frost and a quantitative evaluating method of frost - resistance were put forward 文摘:在分析、比較不同國家現行的鹽凍試驗方法,在研究影響混凝土除冰鹽剝蝕因素的基礎上,對鹽凍試驗方法進行改進,提出更簡易的鹽凍試件制備方法和抗鹽凍性能的量化評價方法。

While rock salt ( nacl ) is relatively abundant and a very cheap deicer , it is endothermic while melting , pollutes the environment and accelerates corrosion of vehicles , bridges , guardrails and reinforcing steel in concrete 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。

The product developed in the experiment enriches the diversity of the deicers , has some application value , and becomes one of the first - choice deicers in cold areas in winter 此次課題開發的產品,豐富了除冰劑的品種,具有一定的應用價值,成為高寒地區冬季冰雪的首選除冰劑之一。

The primary goal to develop a new highly effective deicer is gained 基本實現了開發新型除冰劑的初衷,達到了本課題的研究目的。
