A pipe plier structure includes a first body, a second body, a pivot member, and a locking member. The first body is provided with multiple first teeth, an arc line, an axis, a first vertical line, a radius, a first angle, and a second angle. The second body is provided with multiple second teeth, multiple third teeth, a second vertical line, a first connecting line, a second connecting line, a third angle, a fourth angle, a concave face, a fifth angle, a sixth angle, a seventh angle, and an eighth angle. The pivot member is assembled with the first body and the second body. The locking member is assembled with the first body and the second body. The locking member provides an elastically restoring force to the first body and the second body after the second body is extended outward relative to the first body.

Pipe plier structure

The present invention provides a method of producing hollow silica particles. First, an amine-ketimine compound is mixed with water to obtain a hydrophobic core dispersion, and then an organic siloxane compound and/or a coupling reagent is added into the hydrophobic core dispersion to form a core-shell silica dispersion. Then, the core-shell silica precipitate is separated from the core-shell silica dispersion, and then it is further dispersed and washed by a low carbon alcohol solution. Finally, hollow silica particles in accordance with the present invention are produced. In addition, the present invention also provides hollow silica particles produced by the afore-mentioned method without using any additional surfactant.
