我們都(dou)知道潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)對(dui)(dui)于車輛、機器設(she)備、各(ge)個零部(bu)件(jian)來說，用處是非常大的，不(bu)過(guo)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)生產(chan)廠家(jia)的數量眾多(duo)，他們所生產(chan)的潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)的質(zhi)量也(ye)都(dou)是高低不(bu)同(tong)，我們該如何選擇靠譜的潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)生產(chan)廠家(jia)呢？ 潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)生產(chan)廠家(jia)告訴我們，殼牌潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)批發地址，潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)是由基礎油(you)、稠化劑(ji)(ji)組成，不(bu)過(guo)為了(le)保證潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)的效(xiao)果，通常還會在其中添(tian)加(jia)部(bu)分的添(tian)加(jia)劑(ji)(ji)。而(er)作為基礎并且占大部(bu)分的基礎油(you)的質(zhi)量對(dui)(dui)于潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)的質(zhi)量起到了(le)決(jue)定性的作用。

潤滑(hua)(hua)(hua)脂(zhi)是(shi)(shi)否變質(zhi)(zhi)，需(xu)要通過化(hua)驗分析來判(pan)斷。在沒有(you)化(hua)驗設備和化(hua)驗員的(de)(de)時候，可以(yi)由有(you)經驗的(de)(de)人員來檢查判(pan)斷，一(yi)般潤滑(hua)(hua)(hua)脂(zhi)變質(zhi)(zhi)的(de)(de)原(yuan)因(yin)(yin)及(ji)處理方法如下：潤滑(hua)(hua)(hua)脂(zhi)變稀的(de)(de)原(yuan)因(yin)(yin)之(zhi)一(yi)是(shi)(shi)貯存溫(wen)度(du)過高(gao)，保定潤滑(hua)(hua)(hua)脂(zhi)，或(huo)不能恢復稠度(du)，其(qi)另一(yi)原(yuan)因(yin)(yin)則是(shi)(shi)酸堿度(du)有(you)變化(hua)(用酚(fen)酞指示(shi)劑檢查)。潤滑(hua)(hua)(hua)脂(zhi)變硬原(yuan)因(yin)(yin)之(zhi)一(yi)是(shi)(shi)長期冷凍造成的(de)(de)。這樣可把(ba)它(ta)放在稍(shao)高(gao)的(de)(de)室溫(wen)條件下(例如30-40℃)存放一(yi)段(duan)時間，長城潤滑(hua)(hua)(hua)脂(zhi)批發銷售，使其(qi)恢復原(yuan)狀。這種情況下不能采用過高(gao)溫(wen)度(du)加熱。有(you)些脂(zhi)的(de)(de)硬化(hua)，原(yuan)因(yin)(yin)是(shi)(shi)脂(zhi)本身(shen)的(de)(de)特性，例如合成鈣基脂(zhi)在冬(dong)季有(you)硬化(hua)趨勢。只(zhi)要不影響使用，則不必作上述保溫(wen)處理，只(zhi)需(xu)適(shi)當地攪拌均(jun)勻(yun)。
