1. Rubber modified asphalt (SBS, CR, EVA modification, etc.)
High viscosity, strong shear mixing required
Closed reaction required, temperature and pressure controllable
2. Asphalt rubber for waterproofing membrane
Added with fillers, rubber powder, mineral oil, etc.
High viscoity and high requirements for mixing uniformity
3. Hot melt waterproof coating, sealing asphalt
Such as the base material of bridge deck and roof waterproof coating
High hot melt, difficult to stir, sigma mixer can scrape the wall to mix and avoid coking
4. Road crack potting glue / road repair glue
Heavy-duty sealant with elastomer or resin
Requires high temperature mixing and good dispersion ability
Why choose sigma mixer to produce asphalt?
| Characteristic | Advantages of sigma mixer |
| Asphalt has high melting point (120~180℃) | Can be equipped with thermal oil jacket heating and precise temperature control |
| High viscosity | Double ∑-shaped blades strong stirring, suitable for processes with strong shear force |
| High adhesion | Equipped with wall and bottom scraping system to avoid sticking and local coking |
| Volatile, contains bubbles | Can be equipped with vaccum system to degas and improve quality |
