特性参数
Technical Parameters
| 外观（25℃）Appearance (25℃) | 白色至淡黄色液体或膏状white to light yellow liquid or paste |
| 密度（25℃）Density (25℃) | 850-910kg/m3 |

注：较低温放置后会有结晶析出，属于正常现象，回温后即可恢复，不影响性能。
Note: Crystallization may occur when stored at low temperature. It is a normal phenomenon and will recover after warming up, without affecting performance.
使用方法
Usage Instructions
首先将沥青加入加热釜内加热熔化，脱水，除去杂质后于135-140℃（SBS改性沥青采用165-175℃）下保温备用，另将一定量的水加入乳化剂水溶液配置釜内，加热升至55-60℃，按比例加入乳化剂，搅拌均匀后，加入盐酸，调节pH值至2.0左右。将上述所配制的沥青和乳化剂水溶液按要求同时加入胶体磨，即可得到阳离子型乳化沥青。
First, add the asphalt into the heating kettle to melt, dehydrate and remove impurities, then keep it at 135-140℃ (165-175℃ for SBS modified asphalt) for later use. Meanwhile, add a certain amount of water into the emulsifier solution preparation kettle, heat it to 55-60℃, add the emulsifier in proportion and stir evenly, then add hydrochloric acid to adjust the pH value to about 2.0. Feed the prepared asphalt and emulsifier solution simultaneously into the colloid mill as required to obtain cationic emulsified asphalt.
