Ded'Formelprozedur vu Fiberglasrassis ze heelen fir d'Fierscheng ze heelen, wat imprägnéiert Harz an enger Photovoltaik-héijer integréierter Hochgeschwindigkeits-Polymeriséierungs-Vorrichtung ass, an déi zitt an eng Form ze ziehen oder ze zéien.Wéinst den verschiddenen Typen vun Harze gebraucht, ass et bekannt Aspholyester Fiberglass, Epoxid Fiberglas, a Phenol Fiichtegkeet. Si ass mAll Charakteristike a sengen Mainfeaturen sinn:
1.Good Korrosiounsbeständegkeet. Fiberglasstube kann effektiv géint d'Korrosioun vu Säure, Alkali, Salz a soss anere Medien a onbehandelt Hausrou Kanalisatioun, korrodéierendem Buedem, chemeschen Abwasser a vill chemesch Flëssegkeete widerstoen. Ënner Normal Conditioune kann et méi laangfristeg geséchert ginn.
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. Despecial high temperature resistant resin can also work normally at temperatures above 200°C.
3.gutt frostbeständeg. Ënnert -20 ° C, d'Gefrierdeeler entstinn net an de Röhren.
4. light weight, high strength. Derelative 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.good Wuesstabilitéit. Enhalt eng grouss Betrag vu Schlamm, Sand a Waasser, an de Räis fir Rotatiounsknappheet a Schlagvergleich Versuch. No 3 Millioune Rotatiounen ass d'Tiewe vu Verschleiung op der Mierwannen vum Teströschen: 0,5 mm mm Fortar- a Email-beschichteten Stéier Röhren, 0,52 mm fir Epoxy- an Teerbeschichteten Stellbiller, a Glas- Stéier Röhre fir Uewerflächelen- gehäicht Stahlbecher. Et ass 0,1 mm. Dat mécht FRP verschleiß.
7.good thermal insulation. FRP is non-conductor, and its electrical insulation
is excellent. Deinsulation resistance is between 1012-1015Ω.cm. It is most
suitable for use in transmission. Deheat 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. Deinner wall of the glass pipe is very smooth, and the roughness and frictional resistance are very small. Decoefficient of roughness was 0.0084, while the concrete pipe had an n value of 0.014 and a cast iron pipe of 0.013.
