Asphalt emulsifier is a commonly used road maintenance material in the preventive maintenance process of highways. So, what are the main technical parameters of asphalt emulsifier? Below, Longteng Road, a manufacturer of asphalt emulsifiers, will explain to you. The main technical parameters of asphalt emulsifier include the following aspects:
1. Appearance: The appearance of asphalt emulsifiers varies depending on the type, and may be a milky white or light yellow paste, as well as a brown viscous liquid or a black brown viscous liquid.
2. Active ingredient content: This refers to the content of active ingredients in emulsifiers, usually within a certain range, such as between 40% and 60%, or a specific value, such as 50% ± 5%. There are also products with an active ingredient content of 27% -28%. The content of active substances directly affects the emulsification effect.
3. PH value: The pH value of emulsifiers is also an important parameter, usually between 2 and 5, but may also vary depending on the type of product, such as 5-7. Both excessively high and low pH values can affect the emulsification effect, therefore strict control is required during the production process.
4. Solubility: Asphalt emulsifiers should be able to dissolve in specific solvents, such as hot water or some organic solvents. Some products also need to be fully soluble in acidic water at a ratio of 1:100. Good solubility helps to achieve uniform dispersion of emulsifiers in asphalt.
5. Surface tension: For some emulsifiers, surface tension is also an important parameter, which should be less than 0.05N/m to ensure the stability of lotion.
6. Applicable dosage: This refers to the proportion or amount of emulsifier used in the production of emulsified asphalt. It is usually expressed as a percentage or percentage of the total emulsified asphalt, such as 0.6% -0.8%, 1.5% -2.0%, or 3-5%. The applicable dosage may vary depending on the type of asphalt, usage, and emulsifier type.
These technical parameters collectively determine the performance and effectiveness of asphalt emulsifiers, therefore, when selecting and using asphalt emulsifiers, it is necessary to comprehensively consider these parameters to meet specific application requirements.
