The oxidation resistance of vehicle gear oil is measured by the CRCL60 bench test.
Detergent packaging in a spouted pouch or Stand Up Pouch is very
popular more than 10years. Because the weight of detergent packaging is only
1/7-1/10 of the plastic bottle, which can save a lot of material and freight
cost. Moreover, the printing appearances are more attractive. Many countries
use the spout standing pouch as an environmental
packaging for shampoo, bath and shower wash, washing liquid and other
hair care products. We have a professional production line and staff who have
been works in years in Detergent Packaging. We accept small order and we can
finish them in a short time. If you need any detergent packaging, please just
contact us.

Anti-rust properties The extreme pressure anti-wear agents in gear oils are the main types of agents, and there are many types. The extreme pressure anti-wear agent is also a compound with relatively high chemical activity, which is easily adsorbed by the metal surface (tooth surface) to produce a chemical (or physical) reaction film, thereby preventing metal friction or seizure. In fact, the reaction film produced by the extreme pressure antiwear agent and the metal surface is a rust corrosion of the metal. Therefore, it is necessary to introduce a corrosion inhibitor to create a competitive adsorption between the surface active material and the extreme pressure anti-wear agent on the metal surface to achieve a certain equilibrium state. The sieve sander has certain extreme pressure anti-wear. Sex, without causing excessive rust (rust). The matching of extreme pressure anti-wear and corrosion inhibitors is one of the cores of gear oil formulation technology.
The use of a rust inhibitor alone does not work well in this formulation. The amount of rust inhibitor for No. 2 oil sample reached 0.6, but the corrosion was not significantly improved. On the contrary, the increase of the amount of rust inhibitor will adversely affect the extreme pressure and abrasion resistance of the oil; in the oil sample No. 3-6, the combination of antioxidant and rust inhibitor improves the rust resistance of the oil. And the anti-rust ability is improved with the increase of the amount of antioxidants and rust inhibitors; for the formulation of the whole oil, the amount of anti-rust agent and antioxidant should be from the anti-rust effect and the extreme pressure anti-wear agent A balanced study of the composite effect. In the sense of oxidation resistance, the change in the performance of various aspects of the oil, the deterioration of the quality during use, is caused by the oxidation of the oil. The oxidation resistance of vehicle gear oils was measured using the CRCL60 bench test. Antioxidants have a better effect on improving the oxidation stability of oils, and as the amount increases, the viscosity changes before and after oxidation of oils decrease.
