Problems solved by technology

Its shortcoming is that the resin and curing agent are infiltrated in the ambient air, and the harmful gas volatilizes to cause environmental pollution. At the same time, air bubbles are carried into the sand layer, and holes are formed in the pipe wall, which affects various performance indicators of the product.
This production method has low production efficiency and high equipment operating costs

Embodiment 1

[0037] Example 1: Taking the production of pipes above φ1500 (inclusive) as an example, the quartz sand gradation scheme is as follows: 10 mesh 5-10%, 20 mesh 25-30%, 30 mesh 14-20%, 50 mesh 26-30% , 5-8% for 60 mesh, 3% for 80 mesh. Calcium carbonate powder with a particle size of 1.0 μm is selected as the filling material, and 2.1% continuous untwisted fiber chopped material is added to the mixture.

[0038] After adding 13.4% of the total amount of resin and fully stirring in the mixer, the mixed resin concrete is added to the screw extrusion device, and the resin curing agent is simultaneously input into the extrusion screw through the input pipe, and it is fully mixed with the resin concrete through the rotation of the screw. Mixing, the thickness adjustment device at the outlet ensures accurate adjustment of the sand thickness.

Embodiment 2

[0039] Example 2: For the production of φ800-φ1500, adjust the gradation scheme of quartz sand to: 10 mesh 5%, 20 mesh to 30 mesh 25 to 35%, 50 mesh to 60 mesh 55 to 65%, 80 mesh 0.5%; select 0.8 The calcium carbonate powder of μm particle diameter is filler material, adds 1.8-2.0% continuous untwisted fiber chopped material in the mixture simultaneously, and all the other are the same as embodiment 1.

Embodiment 3

[0040] Example 3: To produce φ800, adjust the quartz sand gradation scheme to: 20 mesh 5%, 30 mesh 16-27%, 40 mesh 23-27%, 50 mesh 21-30%, 60 mesh 7-12%, 80 mesh 5%. Calcium carbonate powder with a particle size of 0.5-0.7 μm is selected as the filling material, and 1.5-2.8% of continuous untwisted fiber chopped material is added to the mixture. All the other are with embodiment 1.

Abstract

A method for producing a pipeline of glass fibre reinforced concrete, it also provides its device. It consists of the steps: put the quartzite of framework material and fill material in the beater to whisk, at the period of whisking, add fibre material cut up and colophony, mix the fore related material together completely; and then extrude the mixture quantificationally of by screw, and then transport the mixture extruded by gauze, and then intertwist and planish it. In this process, content of silicon dioxide of framework quartzite exceed 98%, which has less water content of 0.2%, specific gravity is 1.60-1.65Kg / cm3; fill material is powder of CaCO3, SiO2 or the in the cutting process of pipe produce. The fill material is 5-10% the quantity of colophony concrete; fibre material cut up is 1-3%; there is seriate device of fibre cutting; there is rate accommodate device of quartzite outer which can be disassembled in the exit of extrude.

Description

technical field [0001] The invention relates to a glass fiber reinforced resin concrete pipeline, in particular to a production method for manufacturing the resin concrete pipeline under the condition of a fixed-length winding process. Background technique [0002] The glue-spraying sandblasting method and pre-infiltration method are commonly used in China to make FRP sand-filled pipes. [0003] The glue-spraying sandblasting method is to spray glue directly on the fibers and then sandblast them for winding. This method causes sand and dust to fly and emits harmful gases, which has a serious impact on the environment, and the product quality is unstable, so it has been gradually replaced. [0004] The pre-soaking method is to pre-soak the glass fiber in the resin, spray the curing agent and spread sand. Its shortcoming is that the resin and curing agent are infiltrated in the ambient air, and the harmful gas volatilizes to cause environmental pollution, and at the same time...
