Pump truck lubricant has been widely promoted and used due to its excellent chemical properties. Currently, there are a large number of lubricants on the market, and the quality of the products is difficult to control. The specific judgment methods are:
1. Determination of the solubility of the lubricant. A good lubricant will turn into a viscous and transparent paste after being dissolved in water and stirred. A poor quality lubricant will mostly turn into a turbid state after being dissolved and white insoluble matter will appear at the bottom.
2. Determination of the solubility of lubricant. Usually, lubricants with stable ingredients and good quality can be completely dissolved at room temperature, while lubricants with poor quality may crystallize or harden when dissolved at room temperature. Failure to provide sufficient hot water under winter construction conditions will cause the solubility of the lubricating agent to decrease, affecting the lubricating effect and affecting pumping.
