Description

[Technical field]

[0001] The utility model relates to the technical field of paraffin emulsification, in particular to an online paraffin emulsification system. [Background technology]

[0002] Paraffin dispersion can be used as a waterproofing agent and is widely used in waterproofing of artificial boards. In the past, after the paraffin dispersion was produced, it was usually cooled first and then the packaged paraffin dispersion was transported to the customer's production site for use. This method is not only costly, but also the paraffin dispersion is prone to precipitation and solidification.

[0003] Of course, there are also devices in the prior art that can be installed at the production site and used for online emulsification of paraffin, such as the Chinese utility model patent with application number 201920339492.5, which discloses an online emulsification and dispersion device that can automatically select the formula raw materials. The online emulsification device can be set up at the customer's production site, which is conducive to controlling product quality, and can select the formula of the emulsion (i.e., paraffin dispersion). However, the above existing online emulsification equipment has the following defects in the actual production process: the melted liquid paraffin and emulsifier or dispersant aqueous solution are directly transported to the emulsification device for emulsification, and the emulsification effect is not good. When the emulsified paraffin dispersion cannot meet the use requirements, it is difficult to recycle and reuse the paraffin dispersion.
