如何將融雪劑的危害小(xiao)化

 從(cong)融(rong)雪(xue)效能(neng)、速度、方便快捷(jie)到(dao)成本效益(yi)的(de)比較可以看出，融(rong)雪(xue)劑仍然是難以取代的(de)。不過我(wo)們可以將融(rong)雪(xue)劑的(de)危害小化，大限度地減少使用，以人工除(chu)雪(xue)，機械除(chu)雪(xue)為主(zhu)，融(rong)雪(xue)劑除(chu)雪(xue)為輔，并在使用的(de)同時(shi)，對路橋等設施(shi)附(fu)加保護措施(shi)，盡可能(neng)減少損失。

  對于城市冬季(ji)融(rong)(rong)雪問題，歐美國家目前的(de)(de)環(huan)保(bao)做法是(shi)：機(ji)械鏟(chan)雪后，在道路上撒炭渣、粗(cu)砂、樹枝渣等物質來(lai)防滑，也利(li)用這些渣類物質的(de)(de)深色來(lai)吸收太陽(yang)的(de)(de)熱量，以增加(jia)地(di)面溫度來(lai)融(rong)(rong)雪。使(shi)用后的(de)(de)炭渣和樹枝渣可以放人(ren)道路邊的(de)(de)綠地(di)中，沒(mei)有污染。對實(shi)在需要撒融(rong)(rong)雪劑(ji)的(de)(de)路面，要先用鏟(chan)雪車掃掉地(di)面上的(de)(de)大部分(fen)積雪，然后撒少(shao)量融(rong)(rong)雪劑(ji)來(lai)防止道路上結冰。

環保融雪劑(ji)的功能特點： 綠(lv)色環保，對(dui)橋梁、機(ji)場、鋼軌、路面、綠(lv)化植物及(ji)公共設(she)施基本無傷害，較大限度的降低融雪劑(ji)對(dui)道路及(ji)環境的影響(xiang)和破(po)壞。

應用范(fan)圍(wei)：適用于寒冷地(di)區(qu)各種道路、機場(chang)、公(gong)園等。

干撒(sa)：直接將融雪劑人(ren)工(gong)或(huo)機械(xie)施撒(sa)于雪地。降雪在50毫米(mi)以下(xia)的雪地參考(kao)施撒(sa)量(liang)為(wei)30-50g/m2，50毫米(mi)以上雪或(huo)氣溫過低時應增(zeng)加施撒(sa)量(liang)或(huo)施撒(sa)次數。

融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑，是(shi)一種(zhong)化學(xue)品(pin)。普通融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑原料易(yi)得，價格(ge)低(di)廉，其(qi)成份主要是(shi)醋酸鉀和氯鹽，并(bing)以這(zhe)(zhe)兩種(zhong)進行分類。融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑通過(guo)降(jiang)低(di)冰(bing)雪(xue)(xue)(xue)(xue)融(rong)(rong)(rong)(rong)(rong)(rong)化溫度(du)(du)融(rong)(rong)(rong)(rong)(rong)(rong)化道(dao)(dao)路(lu)上的(de)積雪(xue)(xue)(xue)(xue)，便于道(dao)(dao)路(lu)疏(shu)通，播撒(sa)處(chu)效果明顯，但其(qi)具有危害性(xing)，研究發現(xian)，融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑殘留物可腐蝕路(lu)面和汽車橡膠輪胎。目前北方在常(chang)冬下仍采用沙土和鏟雪(xue)(xue)(xue)(xue)車為主，融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑為輔(fu)的(de)方式清除路(lu)面冰(bing)雪(xue)(xue)(xue)(xue)，保(bao)證交通通暢(chang)。新的(de)要求：隨(sui)著科學(xue)的(de)不(bu)斷進步，研究的(de)不(bu)斷深入，復(fu)合型(xing)融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑價格(ge)，新產品(pin)應該綠色環(huan)保(bao)，對(dui)路(lu)面、綠化植(zhi)物及(ji)公共設施基本無傷害，并(bing)且(qie)融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)速(su)度(du)(du)快(kuai)，投加劑量(liang)小，使(shi)(shi)用成本低(di)。從(cong)(cong)上解決傳(chuan)統的(de)產品(pin)對(dui)道(dao)(dao)路(lu)橋(qiao)梁(liang)的(de)腐蝕問題，較大限度(du)(du)地降(jiang)低(di)融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑對(dui)道(dao)(dao)路(lu)及(ji)環(huan)境(jing)的(de)影響和破壞。融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)殘留的(de)產物可促進植(zhi)物生產，實(shi)現(xian)二次利用，這(zhe)(zhe)樣才能(neng)從(cong)(cong)根本上融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑的(de)危害。同(tong)時(shi)各(ge)級應加大宣傳(chuan)力度(du)(du)，鼓勵推(tui)廣環(huan)保(bao)融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑的(de)使(shi)(shi)用，并(bing)考(kao)慮(lv)給予適(shi)當經(jing)濟補(bu)貼，彌補(bu)環(huan)保(bao)融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑的(de)價格(ge)劣勢，終(zhong)實(shi)現(xian)無機(ji)融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑被(bei)價格(ge)適(shi)宜、環(huan)保(bao)的(de)新型(xing)融(rong)(rong)(rong)(rong)(rong)(rong)雪(xue)(xue)(xue)(xue)劑所替(ti)代。
