Problems solved by technology

But after several years of use, there are still many problems that need to be improved, such as heavy weight and large body that bring inconvenience to transportation and installation, poor tensile and impact strength, easy to break, easy to crack in frost season, and long service life. Short, poor penetration resistance and chemical erosion resistance, fluids are easy to deteriorate and permeate, pollute environmental resources, large water flow resistance, increase transmission power consumption, and its promotion and use are subject to certain restrictions

Embodiment 1

[0016] (1) Weigh the weight of various raw materials by weight: 8 parts of low-alkalinity 325#-525# quick-hardening sulfoaluminate cement, 4 parts of sand, 0.5 part of aggregate bean stone, 0.2 part of glass fiber mesh cloth 0.1 part of regulator lignocalcetin and 3 parts of water; (2) after weighing, cement, sand and aggregate are mixed together and stirred evenly, and the regulator and water are mixed together for pre-polymerization, and the working temperature is 5-38°C; (3) Put the above two kinds of mixtures together with the reinforcing material glass fiber for compounding; (4) Then select the mold according to the pipe diameter and pipe shape, put the composite material into the mold, and centrifuge-suspend (5) Steam curing at 50-65°C for 30 minutes after molding; (6) Water spray curing for 7 days after demoulding, and the finished product can be put into use.

Embodiment 2

[0018] (1) Weigh the weight of various raw materials by weight: 9 parts of low-alkalinity 325#-525# rapid-hardening aluminate cement, 6.5 parts of sand, 2 parts of aggregate bean stone, 0.4 part of glass fiber roving , 0.3 part of regulator lignocalciflavin and 4 parts of water; Following procedure is the same as embodiment 1.

Embodiment 3

[0020] (1) Weigh various raw materials by weight: 10 parts of 325#-525# GRC special cement, 5 parts of sand, 1 part of aggregate bean stone, 0.5 part of glass fiber chopped fiber, 0.2 part of regulator lignocalcetin 1 part and 4 parts of water; the following procedures are the same

Abstract

The present invention has disclosed a kind of water supply and drainage pipe with its raw material share of composition by weight as: cement of 8-10 share, sand for 4-6.5 share, bone material of 0.5-2 share, glass fibre of 0.2-0.5 share, regulator of 0.1-0.3 share and water of 3-4 share. It is fabricated as the following process: 1) to weight the raw materials as per their weight shares; 2) to blend and mix cement, sand and bone material evenly and to carry on prepolymerization for water and regulator; 3) to compound the two mixed materials with glass fibre; 4) to fill the compounded material in model for forming; 5) to make high temperature of steam curing after forming; 6) to make water spraying curing after releasing out from the model.

Description

technical field [0001] The invention relates to a pipe for conveying liquid, in particular to a water supply and drainage pipe and a manufacturing method thereof. Background technique [0002] At present, concrete pipes are used instead of cast iron pipes, and metal pipes are used as water supply and drainage pipes and irrigation pipes, which save a lot of mineral resources. But after several years of use, there are still many problems that need to be improved, such as heavy weight and large body that bring inconvenience to transportation and installation, poor tensile and impact strength, easy to break, easy to crack in frost season, and long service life. Short, impermeability and chemical erosion resistance are poor, the fluid is easy to deteriorate and permeate, pollutes environmental resources, the water flow resistance is large, and the power consumption of transmission is increased, so its popularization and use has been limited. For this reason, the present inventio...
