Embodiment Construction

[0028] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0029] The manufacture method of one-time forming glass magnesium exhaust pipe of the present invention comprises the steps:

[0030] a. The adjacent two sides of three rectangular formworks are movably connected to form an outer mold, the middle one is a bottom formwork, and its two sides are symmetrical side formworks, and the three formworks are placed horizontally;

[0031] b. The four sides of the outer mold formed by placing the above three templates horizontally, that is, the outer long sides and two ends of the two side templates and the two ends of the bottom template are provided with frames, and the frame is higher than the inner height of the inner surface of the outer template and the glass to be made The wall thickness of the magnesium exhaust pipe is the same;

[0032] c. A layer of medium-alkali or alkali-free grid cloth is placed on...

Abstract

The invention discloses a once-formed manufacturing method for a glass magnesium smoke vent. The once-formed manufacturing method comprises the following steps: a. adjacent edges of three rectangular templates are movably connected with one another, the three rectangular templates form an outer mold, and the three rectangular templates are arranged horizontally; b. a frame is arranged on the four edges of the outer mold, namely, the outer long edges and the two end edges of the two side templates and the two end edges of the bottom template; c. a layer of medium-alkali or alkali-free gridding cloth is arranged on the inner face of the outer template, and the gridding cloth extends to the outer side of the side templates; d. glass magnesium pulp is laid on the gridding cloth on the inner frame of the outer template, the glass magnesium pulp is flattened, the thickness of the glass magnesium pulp is the same as the height of the frame, another layer of medium-alkali or alkali-free gridding cloth is laid on the glass magnesium pulp and is flattened; e. a square cylindrical core mold meeting the requirements of shape and standard is placed on the bottom template of the outer mold with the glass magnesium pulp, and the side templates of the outer mold are folded upwards to be perpendicular to the bottom template, and the side templates of the outer mold are fixed; f. glass magnesium pulp is laid on the gridding cloth of the core mold which is well arranged, and the glass magnesium pulp is flattened and solidifies.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a method for manufacturing a once-molded glass magnesium smoke exhaust pipe, and also relates to a mold for realizing the method. Background technique [0002] Smoke exhaust pipes made of glass magnesium materials have been increasingly used in the construction field. The commonly used manufacturing method of glass magnesium smoke exhaust pipe is: first use glass magnesium slurry to make prefabricated panels, then cut the glass magnesium material prefabricated panels, splice them into rectangular tubes, and fasten them with metal parts such as nails and hoops. The shape and specification of the glass magnesium exhaust pipe produced in this way is not easy to keep consistent, and the quality is unstable. During the production process, it will cause pollution and harm to the human body, and the glass magnesium material is easy to corrode metal fasteners, so it is easy to damage th...
