Moreover, a three-dimensional flow field of the retarded adhesive mortar in a single-screw extruder is obtained after supposition, simplification and carrying on the boundary treatment.
结合假设经过简化和边界处理，得出单螺杆挤出机中缓凝砂浆的三维流场。

It is significant for supplementing flame retarded wood theory to study the function of char forming and smoke suppression of zinc borate applied in wood flame retarding field systematically.
The focus of this research field is to study the chemical equipment corrosion mechanisms and protection, thermal controlled safety coating materials and the development of flame retarded materials.
