507826、507834  油液在高壓下經(jīng)過(guò)液壓閥等元件相互滑動(dòng)部分的狹小間隙或縫隙時(shí)，受到很大的剪切作用力，以使高分子斷鏈，引起粘度的*久性下降，失去潤(rùn)滑性，并導(dǎo)致極化分子的產(chǎn)生，引起覆蓋和堵塞現(xiàn)象。這種情況在高溫、高壓狀態(tài)下更為嚴(yán)重。由于粘度的下降，將影響油液的使用壽命。因此，必須加入適當(dāng)?shù)奶砑觿?，以提高油液的抗剪切性能。DBDS30K1X/315

    (八)飽和蒸汽壓要低，沸騰點(diǎn)要高，冰凍點(diǎn)要低，以及高的熱傳導(dǎo)系數(shù)，高的單位熱容量以及小的熱膨脹系數(shù)。
    (九)流動(dòng)阻力小，同時(shí)，不應(yīng)含有瀝青及其他顆粒狀固體雜質(zhì)，以防元件間隙及管道的堵塞。
    (十)能防火、防爆。同時(shí)，對(duì)健康無(wú)害等。     R900476331 ZDR6DP2-4X/150YMV
