 如何預防橡膠接頭被腐蝕?
  橡膠接頭在運用的時候容易被腐蝕造成運用保存生命的年數短,為了進步提升防備盡量照顧作用,在實踐運用時經常選用兩種或兩種以上具有不同作用機理的防老劑進行并用,或選用同一防備盡量照顧機理的防老劑并用,或選用在同一分子上按不同機理起作用的基團同時存在的防老劑,并用后作用有三種。對立效應是指兩種或兩種以上的防老劑并用時,所發作的防備盡量照顧作用小于她們.自運用時的作用之和,實踐運用時應該防止這種景象發作。
  Rubber joint at the time of using easily preserved by corrosion using years of life is short, in order to improve preparedness progress as far as possible to take care of the role, in practice often chooses two or above and with different mechanism of the stabilizer, or choose the same guard to take care of the mechanism of the stabilizer and as far as possible, or to choose according to the different mechanism of action on the same molecular groups of stabilizer at the same time, there are three kinds of effect after using.Oppositional effect refers to that when two or more anti-aging agents are used together, the protective effect is smaller than that of them. The sum of the effects of self-use should prevent this phenomenon from happening in practice.

  研究標示,當顯酸性的防老劑與顯堿性的防老劑并用是,由于兩者將發作相似于鹽的復合物,由于這個發做對頭立效應。別的,一般的鏈斷開型防老劑與某些硫化物尤其是多硫化物之間也發做對頭立效應。在富含1%的4010NA的硫化天然產生的乳膠中,加入多硫化物后使氧化效率進步提升,這也是對立效應。在富含芳胺或受阻酚的過氧化物硫化的純天然產生的乳膠中,加入三硫化物,也發作有相是的景象。對立效應的發作與硫化物的構造有非常大聯系,如二烯鏈硫化物與防老劑有清楚顯露的對立效應,而二正丁基硫化物和三正己基三硫化物則無對立效應。一般單硫化物的影響比多硫化物小。炭黑在橡膠中既有抑氧化的作用,又有助氧化的作用。在鏈斷開型防老劑炭黑按納作用的減小,或在炭黑防老劑防備盡量照顧效能的下降,都清楚地標示她們之間發作了對立效應。
  
Studies have shown that when acidic and alkaline antisenders are used together, because both will attack a compound similar to salt, due to the headstand effect.In addition, the general chain - breaking anti - aging agent and some sulfides, especially polysulfides between head - to - head effect.The addition of polysulphides to natural sulfide latex, which is rich in 1% 4010NA, improves the oxidation efficiency, which is also the opposite effect.The addition of trisulphides to the naturally occurring latex, which is rich in aromatic amines or peroxide sulphides of blocked phenols, also has a similar effect.The occurrence of antagonistic effect is closely related to the structure of sulfides. For example, diene-chain sulfides and anti-aging agents have obvious antagonistic effect, while din-butyl sulphides and trihexyl trisulphides have no antagonistic effect.In general, the effect of monosulfide is less than that of polysulfide.In rubber, carbon black not only has the function of oxidation inhibition, but also helps oxidation.The decrease in sodium content of chain-breaking antioxidant carbon black, or the decrease in the effectiveness of carbon black antioxidant preparedness in trying to take care of aging, clearly marked the onset of opposing effects between them.
