Surfactants can significantly improve the extreme pressure performance of water
2020-07-22 16:37:29

Surfactant industrial cleaning agent manufacturers found that the current industrial cleaning agent industry is almost the same as the "traditional manufacturers", and they basically follow the old road of traditional industrial cleaning agent manufacturers, and the marketing means are also poor. Industrial detergent manufacturers believe that for industrial detergent manufacturers, it is a good choice to boost social marketing with the help of distributors.

In addition, industrial cleaning agents can also learn a new marketing path. Break through the current situation and look for a new pattern. Compared with not knowing how to develop in the trend of industrial cleaning agent e-commerce, it is better to change the thinking mode and attract customers with marketing, so as to promote the development of industrial cleaning agent manufacturers and improve the brand awareness of industrial cleaning agent.

It is found that alkyl imidazoline borate is a kind of multifunctional metal working fluid additive with excellent performance. The results showed that the loading resistance and extreme pressure properties of the aqueous solution could be obviously improved by the combination of oleic acid and oleic acid, and the load resistance (Pb value) of aqueous solution increased with the increase of the proportion of oleic acid imidazoline borate. When the ratio of oleic acid imidazoline borate and oleic acid is 2:1, the Pb value reaches a high value. The compatibility of oleic acid imidazoline borate and sodium dithiocarbamate was also good. When the ratio of them was 1:1, the synergistic effect was good.

In addition, organic compounds, inorganic silicates and organosilicon compounds containing rare earth elements have good performance in water-based cutting fluid. For example, sodium silicate has good compatibility with di-n-butyl phosphite. When the ratio is appropriate, the anti-wear and friction reducing performance of sodium silicate in water-based fluid can be better exerted. A water soluble rare earth complex CE DOP was synthesized by Lin Feng et al. The experimental results show that the extreme pressure performance of water can be significantly improved when the content of CE DOP in water is about 2% (mass fraction).

The friction coefficient and emulsification of the solution obtained by dissolving these surfactants in water alone are similar or even smaller. If there is no polar group in the emulsified oil and surfactant, the friction coefficient will increase. This is because surfactants with polar groups can form physical or chemical adsorption on the metal surface, and the adsorption film is relatively firm, which can play a good lubricating effect.

Synthetic cutting fluid does not contain oil and its lubricating effect mainly depends on surfactant. As long as proper surfactant is selected, synthetic cutting fluid may reach or exceed the lubricating level of emulsion cutting fluid. In the formulation of hw-5 high water base cutting fluid, water-soluble lubricants (such as polyvinyl alcohol, glycerin, etc.) are selected and mixed with anionic surfactant and non-ionic surfactant. 5% hw-5 aqueous solution, its large non bite load Pb value reached 61 kg, and the Pb value of emulsion at the same concentration was less than 40 kg.
