Ko tete hangahanga o nga ngongo tube ki te rongoa i te fiberglass e whakatairangahia ana i roto i te whakamahinga o te hangarau polymerization integrated heat-vitivic heater, a muri iho ka toia ki te tarai.No te momo momo o nga rehu whakamahia, ka mohiotia ko te pounamu kopolyester, te epoxy fiberglass, me te fiberglass.It he mko nga ahuatanga me nga waahanga whaimana e whai ake nei:
1.Ia te painga o te waikura. Ka taea e Fiberglasstube te whakatairanga i te paheketanga o te waikawa, te alkali, te tote me etahi atu papaawe me nga wehenga o te taiao kaore i tukuna, he oneone pakaru, he wai taiao me nga waihanga maha. I raro i nga wa e tika ana, ka taea e te pupuri i te haumaru roa.
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. Ko tespecial high temperature resistant resin can also work normally at temperatures above 200°C.
3.a te aukati huka. Kei raro iho -20 ° C, kaore nga waapa miihini e puta i roto i nga ngongo.
4. light weight, high strength. Ko terelative 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. whakaekea te kaha. Kei roto i te nui o te paru, te onepu me te wai, ki roto i te tauera mo te kakahu hurihuri me te whakamatau i te whakatairanga. Muri iho i te 3 miriona nga huringa, ko te hohonu o te kakahu i runga i te taiepa o roto o te ngongo whakamatautau e whai ake nei: ko te 0.53 mm te paera me te ngongo o te maitai whakawairahu, 0.52 mm mo nga waimaro-me te karaihe, me nga karaihe karaihe mo te mata- nga uaua pakeke. Ko te 0.21mm te reira.
7.good thermal insulation. FRP is non-conductor, and its electrical insulation
is excellent. Ko teinsulation resistance is between 1012-1015Ω.cm. It is most
suitable for use in transmission. Ko teheat 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. Ko teinner wall of the glass pipe is very smooth, and the roughness and frictional resistance are very small. Ko tecoefficient of roughness was 0.0084, while the concrete pipe had an n value of 0.014 and a cast iron pipe of 0.013.
