無鋅無灰HM液壓油和CKC潤滑油
無鋅無灰HM液壓油和CKC潤滑油
在過去幾年中，無鋅液壓油逐漸受到歡迎。
在許多情況下，必須使用無鋅液壓油，尤其是在液壓油可能污染金屬加工液的機(jī)床上。Renolin ZAF B液壓油是符合ISO 6743-4的無鋅和無灰HM液壓油。
Realin ZAF B液壓油最重要的特點(diǎn)是：
良好的氧化安定性和良好的耐老化性
強(qiáng)大的極壓性能和良好的磨損保護(hù)
優(yōu)良的防腐性能
快速放氣，低發(fā)泡
破乳性能好
與密封材料相容性好
應(yīng)用：
Renolin ZAF B產(chǎn)品是符合ISO 6743-4的高等級HM液壓油，可用于所有液壓系統(tǒng)，也可作為符合ISO 6743-6的齒輪箱、軸承和循環(huán)系統(tǒng)中的CKC潤滑油。建議在液壓油和金屬加工液接觸的機(jī)床上使用Renolin ZAF B產(chǎn)品。
