Secondly, coating an adhesion promoter on the surface layer of the quartz rod after washing; the adhesion promoter has better adhesion effect on the quartz rod.
Thirdly, drying the quartz rod coated with the adhesion promoter, placing the dried quartz rod in a wax sticking groove, pouring the adhesion promoter into the wax sticking groove, and wrapping the quartz rod with the adhesion promoter; and (3) carrying out wax sticking treatment on the quartz rod.
Fourthly, standing the quartz rod wrapped by the adhesive for 30-40min at normal temperature, and solidifying and molding the quartz rod wrapped by the adhesive; the quartz rod is fixed by using the adhesive, so that relative vibration cannot be generated during cutting of the quartz rod.
