潤滑脂

       東光縣新宇化工專業的潤滑脂專家，潤滑脂英文(wen)名：lubricating grease；grease 稠(chou)厚的(de)油脂狀半固體。用(yong)于(yu)機(ji)械的(de)摩擦部分，起潤滑和(he)(he)密封(feng)作(zuo)用(yong)。也用(yong)于(yu)金屬表(biao)面，起填(tian)充空隙(xi)和(he)(he)防銹作(zuo)用(yong)。主要(yao)由礦物(wu)油（或合成潤滑油）和(he)(he)稠(chou)化劑調制而成。

       根據稠(chou)化劑(ji)(ji)可(ke)分(fen)為(wei)皂(zao)基(ji)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)和(he)非皂(zao)基(ji)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)兩(liang)類。皂(zao)基(ji)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)稠(chou)化劑(ji)(ji)常(chang)(chang)用(yong)鋰、鈉(na)、鈣、鋁、鋅等(deng)金屬皂(zao)，也  潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)用(yong)鉀、鋇、鉛、錳等(deng)金屬皂(zao)。非皂(zao)基(ji)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)稠(chou)化劑(ji)(ji)用(yong)石墨、炭黑、石棉還有(you)合成(cheng)的(de)(de)(de)(de)（如(ru)聚脲基(ji)、膨潤(run)(run)土），根據用(yong)途可(ke)分(fen)為(wei)通用(yong)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)和(he)專用(yong)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)兩(liang)種(zhong)，前者(zhe)用(yong)于一般機(ji)(ji)(ji)械(xie)零件，后者(zhe)用(yong)于拖(tuo)拉機(ji)(ji)(ji)、鐵道機(ji)(ji)(ji)車、船舶(bo)機(ji)(ji)(ji)械(xie)、石油鉆井機(ji)(ji)(ji)械(xie)、閥門等(deng)。主要質量指標是(shi)滴(di)點(dian)(dian)、針入(ru)度、灰分(fen)和(he)水分(fen)等(deng)。用(yong)來評價(jia)(jia)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)膠體(ti)穩定(ding)性(xing)的(de)(de)(de)(de)指標為(wei)分(fen)油試(shi)(shi)(shi)(shi)驗(yan)(yan)、滾(gun)動軸承性(xing)能試(shi)(shi)(shi)(shi)驗(yan)(yan)等(deng)。滾(gun)筒試(shi)(shi)(shi)(shi)驗(yan)(yan)是(shi)測試(shi)(shi)(shi)(shi)滾(gun)壓作(zuo)(zuo)用(yong)下(xia)稠(chou)度變化的(de)(de)(de)(de)試(shi)(shi)(shi)(shi)驗(yan)(yan)方法(fa)。流(liu)(liu)動性(xing)試(shi)(shi)(shi)(shi)驗(yan)(yan)是(shi)評價(jia)(jia)在(zai)低(di)溫(wen)下(xia)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)可(ke)泵送性(xing)的(de)(de)(de)(de)試(shi)(shi)(shi)(shi)驗(yan)(yan)方法(fa)。抗水淋(lin)性(xing)試(shi)(shi)(shi)(shi)驗(yan)(yan)是(shi)評價(jia)(jia)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)對水淋(lin)洗出(chu)的(de)(de)(de)(de)抵(di)抗能力的(de)(de)(de)(de)試(shi)(shi)(shi)(shi)驗(yan)(yan)方法(fa)。膠體(ti)安定(ding)性(xing)是(shi)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)在(zai)貯存和(he)使用(yong)中(zhong)(zhong)(zhong)保(bao)持(chi)膠體(ti)穩定(ding)，液體(ti)礦(kuang)油不(bu)從脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)中(zhong)(zhong)(zhong)析(xi)出(chu)的(de)(de)(de)(de)性(xing)能。機(ji)(ji)(ji)械(xie)安定(ding)性(xing)是(shi)表(biao)示潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)在(zai)機(ji)(ji)(ji)械(xie)工作(zuo)(zuo)條(tiao)件下(xia)抵(di)抗稠(chou)度變化的(de)(de)(de)(de)性(xing)能。滾(gun)珠軸承扭(niu)矩(ju)試(shi)(shi)(shi)(shi)驗(yan)(yan)是(shi)評價(jia)(jia)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)低(di)溫(wen)性(xing)能的(de)(de)(de)(de)一種(zhong)試(shi)(shi)(shi)(shi)驗(yan)(yan)方法(fa)。潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)是(shi)將稠(chou)化劑(ji)(ji)分(fen)散(san)于液體(ti)潤(run)(run)滑(hua)(hua)(hua)劑(ji)(ji)中(zhong)(zhong)(zhong)所組成(cheng)的(de)(de)(de)(de)一種(zhong)穩定(ding)的(de)(de)(de)(de)固體(ti)或半固體(ti)產品，其中(zhong)(zhong)(zhong)可(ke)以加(jia)(jia)入(ru)旨在(zai)改善(shan)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)某(mou)種(zhong)特性(xing)的(de)(de)(de)(de)添加(jia)(jia)劑(ji)(ji)及(ji)填料(liao)。潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)在(zai)常(chang)(chang)溫(wen)下(xia)可(ke)附著于垂直表(biao)面不(bu)流(liu)(liu)失，并能在(zai)敞(chang)開或密封不(bu)良的(de)(de)(de)(de)摩擦(ca)部(bu)位工作(zuo)(zuo)，具有(you)其它潤(run)(run)滑(hua)(hua)(hua)劑(ji)(ji)所不(bu)可(ke)替代的(de)(de)(de)(de)持(chi)點(dian)(dian)。一般而言，相同皂(zao)基(ji)的(de)(de)(de)(de)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)相容性(xing)較好。有(you)機(ji)(ji)(ji)粘土基(ji)與其他基(ji)不(bu)相容。因此，在(zai)汽車和(he)工程機(ji)(ji)(ji)械(xie)上的(de)(de)(de)(de)許(xu)多部(bu)位都(dou)使用(yong)潤(run)(run)滑(hua)(hua)(hua)脂(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)作(zuo)(zuo)為(wei)潤(run)(run)滑(hua)(hua)(hua)材料(liao)，即我們常(chang)(chang)說的(de)(de)(de)(de)機(ji)(ji)(ji)用(yong)黃油！
