APIEZON Vacuum grease user FAQ and answers

问1:如何清理Apiezon烃基润滑脂?

答:用柔软、无棉绒布即可擦除多余的润滑脂。任何残留润滑脂都可用温肥皂水及所有芳香烃溶液(甲苯、二甲苯)洗去。至于更环保的溶液,建议使用柠檬烯。不能使用酒精(乙醇、异丙醇)或酮类(丙酮、丁酮)进行清理。

问2:如何清理Apiezon全氟聚醚润滑脂?

答:多余润滑脂可用无棉绒布擦除。残留润滑脂可用全氟溶剂清除。如对清洁效果要求较高,建议用丙酮进行进一步清理。

问3:Apiezon系列产品的保存时间多长?

答:除了全氟聚醚501 保存期限是4 年外,其他所有Apiezon产品在原包装未开封并置于环境温度储存的情况下 (10 - 30°C),保存期限均为 10 年(自生产日期起)。如果您向我们提供产品外包装上的六位数批号(如023456),我们可以告诉您生产日期。

问4:Apiezon真空油脂在开封后能保存多久?

答:Apiezon润滑脂复杂的化学结构使其具有较强的“吸气”性,这意味着本品极易吸收空气中的蒸汽,特别是水蒸气及其它碳氢化合物。如果吸收了挥发性蒸汽,润滑脂便会失去其很好的蒸汽压力特性,直到这些污染物被去除。这就是我们采用防蒸汽铝管包装润滑脂的原因。我们无法控制润滑脂的使用,所以一旦开封,我们无法判断其保存时间。如果注意用后立刻将管帽盖好,将其与挥发物隔离,保存时间会长一些。除了吸收挥发物,本品性质稳定,预计长时间保存都不会产生其它变化。全氟聚醚 501 为全氟聚醚基润滑脂,具有高度惰性,比烃基润滑脂更难吸收空气中的蒸汽。

问5:Apiezon真空油脂是否通过无铅认证?
答:所有 Apiezon的真空油脂产品均通过无铅认证。任何产品都不含有多溴化联(二)苯 (PBB) ,多溴联苯醚 (PBDE) ,十溴二苯醚,也没有使用铅、镉、汞或六价铬做配方制造。重金属含量列于下表:

问6:Apiezon真空润滑脂是不含硅的吗?

答:是的,所有的Apiezon产品都不含硅。

问7:Apiezon润滑脂在熔点之上会怎样?

答:除 H 型润滑脂外,所有润滑脂都会液化,但如温度上升不大,冷却后会恢复常态及正常特性。全氟聚醚 501 的熔点高于其操作温度极限 250°C,因此不应超过这个温度。

问8:何种O型圈材料可与Apiezon烃基油及润滑脂兼容?

答:Apiezon烃基油及润滑脂不含硅,可与诸多O型圈材料兼容,其中包括:氟橡胶、硅、腈类(>30% 的腈含量)、尼龙、聚氨酯、聚乙烯及聚丙烯。因为其烃基成分,所以不与三元乙丙橡胶、乙丙橡胶、丁基橡胶、聚氯乙烯密封圈兼容。

问9:何种O型圈材料可与Apiezon全氟聚醚501 润滑脂兼容?

答:Apiezon全氟聚醚 501 润滑脂是一款全氟聚醚基润滑脂,与所有常见塑料、橡胶及高分子材料兼容。

问10:Apiezon烃基润滑脂是否具有抗酸蒸汽能力或抗氯性?

答:Apiezon烃基润滑脂以分子蒸馏烃为基础,因此具有高度抗酸试剂能力及抗氯性。

问11:Apiezon全氟聚醚501 润滑脂是否具有抗酸蒸汽能力或抗氯性?

答:Apiezon全氟聚醚润滑脂是一款全氟聚醚基润滑脂,除全氟聚醚基油与路易氏酸催化剂外,对所有的酸、溶剂及腐蚀物具有极强抗性。

Question 12: Is Apiezon W sealing wax resistant to strong acid and alkali corrosion solutions?

A: Yes, it is widely used as an anti-etch ingredient up to 75°C in various etchants including Potassium Hydroxide, Tetramethylammonium Hydroxide, EDP, Hafnium, Nitric Acid and Sodium Hydroxide.

Question 13: Are Apiezon greases suitable for oxygen environments (or liquid oxygen environments)?

Answer: Because hydrocarbon-based greases have a slight spontaneous combustion hazard, only PFPE 501 in the Apiezon range can be used under these conditions .

Question 14: Are Apiezon greases radiation resistant?

Answer: Apiezon L and M greases show some degree of radiation resistance, with only a relatively small increase in stiffness after irradiation with 4 MV electrons to a level of about 100 Mrad. The lubricating properties of the grease remained satisfactory after this exposure, and indeed after a higher degree of irradiation, although the stiffness increased more rapidly. With high levels of irradiation, small amounts of gases (mainly methane and ethylene) are gradually formed, so the grease loses its very low vapor pressure characteristics. Nonetheless, it is clear that Apiezon L and M greases perform much better than other high vacuum lubricants such as silicones, esters and halogenated products at high levels of irradiation.

Question 15: Does Apiezon Grease Luminous Under UV Radiation Grease Show?

A: Yes, they both fluoresce blue.
