Bitumen Emulsifier Medium Cracking Type
This kind of emulsifier is mainly used for spraying through and sticky layers.
1. Main technical indicators:
① Active ingredient content: 55±1%
② PH value: 3-8
③ Appearance: milky white or light yellow paste
④ Odor: non-toxic, aromatic
⑤ Solubility: soluble in hot water and some organic solvents
2. Usage and dosage: The dosage accounts for 8‰-10‰ of the total emulsified bitumen. The dosage of different bitumen is different, and the best dosage is determined by experiment.
① Water temperature: 55-70℃ (emulsifier aqueous solution)
② Bitumen temperature: 125-130℃
③ Emulsifier: 6-8‰ (90# bitumen)
④ Proportion: bitumen: Water = 5:5
3. Matters needing attention:
This product is a paste. In actual production, the following methods can be used: first add an appropriate amount of water in the configuration box, add the measured emulsifier into the water, heat up to 80-85 degrees, start stirring and observe when the emulsifier is completely dissolved, Then add all the remaining water into the configuration box, so that the emulsifier is completely dissolved and foam is reduced, and the water temperature is reduced to the normal temperature.
