style="text-indent:25px">磷酸鹽型：無機磷酸鹽型緩蝕體系以磷酸鹽和硼砂為主劑，不含硅酸鹽。該體系對冷卻系統(tǒng)中鋼、鑄鐵有較好的保護作用，對鋁也有一定保護作用，適合以鋼、鑄鐵為主要材質(zhì)的發(fā)動機冷卻系統(tǒng)。但研究發(fā)現(xiàn)，磷酸鹽在高溫條件下對鋁的保護作用減弱，硼砂還將促進鋁合金傳熱腐蝕。因此，該體系不適合以鑄鋁合金為主要材質(zhì)的發(fā)動機冷卻系統(tǒng)。再者，磷酸鹽會與硬水中的鈣、鎂離子結(jié)合形成絮狀物沉淀，阻塞散熱器盤管，造成冷卻液流動不暢，產(chǎn)生過熱現(xiàn)象;而且當水中磷酸根濃度超過10mg/kg時，即可產(chǎn)生富營養(yǎng)化，加重水質(zhì)污染，不利于環(huán)保。因此，20世紀70年代后，法律對磷酸鹽的使用加以嚴格限制，以磷酸鹽為主劑的緩蝕體系逐漸被淘汰。烏魯木齊市原裝冷卻液廠家</p><div

style="text-indent:25px">有機酸型：有機酸配方有的只使用有機酸緩蝕劑和銅特點緩蝕劑，有的以有機酸緩蝕劑為主，含少量無機緩蝕劑。有機酸緩蝕劑主要指含4個碳原子以上的一元酸和6個碳原子以上的二元酸及相應的鹽，對冷卻系統(tǒng)中的鋼鐵及鋁等多種金屬都有保護作用，而且在使用中消耗緩慢，用于輕負荷發(fā)動機冷卻液可以明顯延長冷卻液的使用壽命；用于重負荷發(fā)動機冷卻液，則可以免除添加延效劑的麻煩，因而同時受到輕負荷和重負荷發(fā)動機冷卻液的青睞，是近年來應用較多的一類緩蝕劑。有機酸型冷卻液的主要技術(shù)難點是選擇合適的抗泡劑以及解決玻璃器皿腐蝕、傳熱腐蝕和模擬使用腐蝕中鋁片變黑的問題。經(jīng)過多方面試驗研究，目前在這方面取得了較大進展。</p><p style="text-indent:25px">冷卻液由水、防凍劑、添加劑三部分組成，按防凍劑成分不同可分為酒精型、甘油型、乙二醇型等類型的冷卻液。酒精型冷卻液是用乙醇(俗稱酒精)作防凍劑，價格便宜，流動性好，配制工藝簡單，但沸點較低、易蒸發(fā)損失、冰點易升高、易燃等，現(xiàn)已逐漸被淘汰；甘油型冷卻液沸點高、揮發(fā)性小、不易著火、腐蝕性小，但降低冰點效果不佳、成本高、價格昂貴，用戶難以接受，只有少數(shù)北歐等仍在使用；乙二醇型冷卻液是用乙二醇作防凍劑，并添加少量抗泡沫、防腐蝕等綜合添加劑配制而成</p><div

style="text-indent:25px">冷卻液，全稱應該叫防凍冷卻液，意為有防凍功能的冷卻液，防凍液可以防止寒冷季節(jié)停車時冷卻液結(jié)冰而脹裂散熱器和凍壞發(fā)動機氣缸體，但是我們要糾正一個誤解，防凍液不**是冬天用的，它應該全年使用，汽車正常的保養(yǎng)項目中，每行駛一年，需更換發(fā)動機防凍液。烏魯木齊市汽車冷卻液價格多少</p><p
