eienskappe van veselglas buis

2018-05-23

Dievormingsproses van veselglas tubeis om die veselglas wat 'n geïmpregneerde hars in 'n fotovoltaïese hitte geïntegreerde hoëspoed-polimerisasie-toestel is, te genees, en trek of teken in 'n gietvorm.As gevolg van die verskillende tipes harse wat gebruik word, is dit bekend aspolyester veselglas, epoksie veselglas, en fenoliese veselglas. Dit het menige eienskappe en sy hoofaktiwiteite is soos volg:

 


1. Goeie korrosieweerstand. Fiberglasstube kan die korrosie van suur, alkali, sout en ander mediaand onbehandelde huishoudelike riool, korrosiewe grond, chemiese afvalwater en baiechemiese vloeistowwe effektief weerstaan. Onder normale omstandighede kan dit langtermyn veilige werking behou.

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. Diespecial high temperature resistant resin can also work normally at temperatures above 200°C.

3. goeie rypweerstand. Onder -20 ° C word daar nie in die buise bevriesings gebreek nie.

4. light weight, high strength. Dierelative 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. goeie dra weerstand. Hou 'n groot hoeveelheid modder, sand en water in diepyp vir rotasie dra en impak vergelykingstoets. Na 3 miljoen rotasies, is die diepte van die slijtage op die binnenste wand van die proefbuis soos volg: 0,53 mm fortar en emalje beklede staal buizen, 0,52 mm vir epoxy-en teer bedekte stalen buizen en glas stalen buizen vir oppervlak- verharde staalbuise. Dit is 0.21mm. Dit maak FRP slijtvast.
7.good thermal insulation. FRP is non-conductor, and its electrical insulation is excellent. Dieinsulation resistance is between 1012-1015Ω.cm. It is most suitable for use in transmission. Dieheat 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. Dieinner wall of the glass pipe is very smooth, and the roughness and frictional resistance are very small. Diecoefficient of roughness was 0.0084, while the concrete pipe had an n value of 0.014 and a cast iron pipe of 0.013.
