閃(shan)(shan)點(dian)(dian)是(shi)表示(shi)油(you)品蒸(zheng)發(fa)(fa)性(xing)(xing)的(de)(de)(de)(de)一項(xiang)指標。油(you)品的(de)(de)(de)(de)餾分(fen)(fen)越(yue)(yue)(yue)輕(qing)，蝸輪(lun)(lun)蝸桿油(you)批發(fa)(fa)，蒸(zheng)發(fa)(fa)性(xing)(xing)越(yue)(yue)(yue)大(da)，其閃(shan)(shan)點(dian)(dian)也越(yue)(yue)(yue)低(di)。反之，油(you)品的(de)(de)(de)(de)餾分(fen)(fen)越(yue)(yue)(yue)重，蒸(zheng)發(fa)(fa)性(xing)(xing)越(yue)(yue)(yue)小，蝸輪(lun)(lun)蝸桿油(you)，其閃(shan)(shan)點(dian)(dian)也越(yue)(yue)(yue)高(gao)。同(tong)時，閃(shan)(shan)點(dian)(dian)又是(shi)表示(shi)石油(you)產品著(zhu)火危(wei)險性(xing)(xing)的(de)(de)(de)(de)指標。油(you)品的(de)(de)(de)(de)危(wei)險等級是(shi)根據閃(shan)(shan)點(dian)(dian)劃(hua)分(fen)(fen)的(de)(de)(de)(de)，閃(shan)(shan)點(dian)(dian)在45℃以(yi)下為快燃品，45℃以(yi)上為可燃品，在油(you)品的(de)(de)(de)(de)儲運(yun)過程中嚴禁將油(you)品加(jia)熱到它的(de)(de)(de)(de)閃(shan)(shan)點(dian)(dian)溫度。在粘度相同(tong)的(de)(de)(de)(de)情(qing)況下，閃(shan)(shan)點(dian)(dian)越(yue)(yue)(yue)高(gao)越(yue)(yue)(yue)好。

用于(yu)(yu)潤滑(hua)齒(chi)輪(lun)(lun)傳動(dong)裝置包括蝸(gua)輪(lun)(lun)蝸(gua)桿副的潤滑(hua)油(you)(you)稱(cheng)(cheng)為齒(chi)輪(lun)(lun)油(you)(you)（L-C）。按(an)GB 7631.7-89規定，齒(chi)輪(lun)(lun)油(you)(you)分為工(gong)(gong)(gong)業閉式(shi)齒(chi)輪(lun)(lun)油(you)(you)、工(gong)(gong)(gong)業開式(shi)齒(chi)輪(lun)(lun)油(you)(you)、車輛齒(chi)輪(lun)(lun)油(you)(you)。用于(yu)(yu)流體靜(jing)壓(ya)(液(ye)(ye)壓(ya)傳動(dong))系統(tong)(tong)中的工(gong)(gong)(gong)作介(jie)質稱(cheng)(cheng)為液(ye)(ye)壓(ya)油(you)(you)，而用作流體動(dong)壓(ya)(液(ye)(ye)力傳動(dong))系統(tong)(tong)中的工(gong)(gong)(gong)作介(jie)質則稱(cheng)(cheng)為液(ye)(ye)力傳動(dong)油(you)(you)，通(tong)常(chang)將(jiang)二者(zhe)統(tong)(tong)稱(cheng)(cheng)為液(ye)(ye)壓(ya)油(you)(you)(L-H)。液(ye)(ye)壓(ya)油(you)(you)與發(fa)動(dong)機油(you)(you)相比較(jiao)，液(ye)(ye)壓(ya)油(you)(you)除具有(you)(you)發(fa)動(dong)機油(you)(you)的基本性(xing)(xing)能外(wai)，還(huan)具有(you)(you)良好的抗(kang)(kang)乳化性(xing)(xing)、抗(kang)(kang)磨性(xing)(xing)、水解安定性(xing)(xing)、可(ke)濾性(xing)(xing)、抗(kang)(kang)泡(pao)性(xing)(xing)和(he)空氣(qi)釋放(fang)性(xing)(xing)。

由于(yu)其(qi)主要原料(liao)(liao)基礎油(you)(you)約占(zhan)公司(si)生產(chan)成(cheng)本的90%，原料(liao)(liao)基礎油(you)(you)及產(chan)成(cheng)品潤(run)滑油(you)(you)的價格均隨著(zhu)國際油(you)(you)價格變化(hua)不斷波動(dong)。根據申報(bao)材料(liao)(liao)披露的敏感性分(fen)析(xi)，蝸輪蝸桿油(you)(you)單(dan)價，2010年基礎油(you)(you)采(cai)購價格每增加1%，毛(mao)利下降6.58%，利潤(run)總額(e)下降14.08%。與同行業其(qi)他(ta)企業相(xiang)比，抗風險(xian)能力(li)不強。而(er)且，高科石化(hua)也沒有在申報(bao)材料(liao)(liao)中(zhong)充分(fen)披露應對原材料(liao)(liao)價格波動(dong)風險(xian)的有效措(cuo)施。
