Detformingprocessen af glasfiberrør til hærdning af glasfiberen, som er imprægneret harpiks i en solcellevarme integreret højhastighedspolymerisationsindretning, og trækker eller trækker i en støbning.På grund af de forskellige typer af harpikser, der er brugt, er det kendt aspolyester glasfiber, epoxy glasfiber og phenolisk glasfiber. Det har mAlle egenskaber og hovedegenskaber er som følger:
1. God korrosionsbestandighed. Fiberglasstube kan effektivt modstå korrosion af syre, alkali, salt og andre medier og ubehandlet husholdningsaffald, ætsende jord, kemisk spildevand og mangekemiske væsker. Under normale omstændigheder kan den opretholde langvarig sikker drift.
2.Good aging resistance and heat resistance. Glass fiber tube can be used in the temperature range of -40°C～70°C for a long period of time. Detspecial high temperature resistant resin can also work normally at temperatures above 200°C.
3. god frost modstand Under -20 ° C opstår der ikke fryser i rørene.
4. light weight, high strength. Detrelative density is between 1.5 and 2.0, only 1/4 to 1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared with that of high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, spacecraft, high-pressure vessels, and other applications that need to reduce its own weight.
6. god slidstyrke Indeholde en stor mængde mudder, sand og vand, i røret til rotations slid og slagprøvning. Efter 3 millioner rotationer er sliddybden på testrørets indvendige væg som følger: 0,53 mm fortar og emaljebelagte stålrør, 0,52 mm til epoxy- og tjærebelagte stålbuer og glasstålrør til overflade- hærdet stålrør. Det er 0,21 mm. Dette gør FRP slidbestandigt.
7.good thermal insulation. FRP is non-conductor, and its electrical insulation
is excellent. Detinsulation resistance is between 1012-1015Ω.cm. It is most
suitable for use in transmission. Detheat transfer coefficient of glass fiber
reinforced plastic area and multi-dose mine area is very small, only 0.23. In
five points, the pipeline has excellent insulation properties.
8.small friction resistance, high transmission capacity. Detinner wall of the glass pipe is very smooth, and the roughness and frictional resistance are very small. Detcoefficient of roughness was 0.0084, while the concrete pipe had an n value of 0.014 and a cast iron pipe of 0.013.
