Fiberglass Kulimbitsa Mapaipi a Pulasitiki: Makhalidwe Aukadaulo ndi Zoyembekeza Zamsika

Fiberglass Yolimbitsa Mapaipi a Pulasitiki: Chitoliro Chatsopano Chophatikizika Chokhala ndi Kuchita Kwapamwamba Kwambiri ndi Ntchito Zambiri

Fiberglass yolimbitsa mapaipi apulasitiki(mapaipi a FRP) ndi mapaipi ophatikizika opangidwa ndi zolimbitsa magalasi ndi utomoni ngati matrix, omwe amapereka zonse zopepuka komanso zolimba. Zosachita dzimbiri komanso zosavuta kuziyika, zakhala njira yodalirika yosinthira mapaipi achitsulo akamamanga pomanga ndi njira zotumizira mphamvu. M'munsimu muli chithunzithunzi chokhudza zinthu zakuthupi, miyezo yopangira zinthu, ndi deta yamsika.

Tanthauzo ndi Mapangidwe a Zinthu

Dongosolo loyambira la mapaipi a FRP limatsatira mfundo zolimba zadziko:

Wosanjikiza wolimbikitsira amagwiritsa ntchito alkali-free kapena sing'anga-alkali wosapindika galasi fiber roving (GB/T 18369-2008), pomwe kuchuluka kwa ulusi kumakhudza mwachindunji kuuma kwa mphete;

Matrix a resin amakhala ndi unsaturated polyester resin (GB/T 8237) kapena epoxy resin (GB/T 13657). Utoto wamtundu wa chakudya (GB 13115) ndiwovomerezeka pamapaipi amadzi amchere;

Mchenga wodzaza ndi mchenga umakhala ndi mchenga wa quartz (SiO₂ chiyero> 95%) kapena calcium carbonate (CaCO₃ kuyera> 98%), ndi chinyezi chomwe chimayendetsedwa mosamalitsa pansi pa 0.2% kuti zitsimikizidwe kuti zimamatira mwamphamvu.

Kupanga Technology

Njira zazikuluzikulu zimaphatikizira kupendekera kwautali wokhazikika, kuponyera kwapakati, ndi mafunde mosalekeza. Njira yokhotakhota imalola kusintha chiŵerengero cha mphamvu pakati pa mayendedwe axial ndi circumferential popanga ngodya za ulusi. Kuchuluka kwa mchenga wodzaza mchenga kumakhudza mwachindunji kuuma kwa chitoliro.

Connection Solutions

Ikani patsogolo zisindikizo zamtundu wa O-ring (zotha kukhala ndi ± 10mm matenthedwe matenthedwe). Pakugwiritsa ntchito mankhwala, kulumikizana kwa flange (PN10/PN16 pressure ratings) kumalimbikitsidwa. Kuyika kuyenera kutsata ndondomeko ya ntchito ya dual-hoist point.

Zochitika Zofananira za Ntchito

Zomangamanga: Mipope yayikulu (DN800+) imatha kusintha mapaipi a konkire. Ndi mkati mwa roughness coefficient ya 0.0084 yokha, mphamvu yothamanga imaposa mapaipi a HDPE ndi 30%.

Ma Ducts a Mphamvu: Kuyika maliro mwachindunji ndi kuuma kwa mphete ≥8 kN/m² kumathetsa kufunika kotsekera konkire.

Chemical Conveyance: Kukana kwa Acid ndi alkali kumakwaniritsa miyezo ya ASTM D543, yokhala ndi moyo wopanga wopitilira zaka 50.

Kuthirira Mthirira: Kulemera gawo limodzi mwa magawo anayi a mapaipi achitsulo, zoyendetsa ndi zoikamo zitha kuchepetsedwa ndi 40%.

Mkhalidwe Wamafakitale ndi Kusanthula Zomwe Zachitika

Kukula Kwa Msika

Padziko lonse lapansiMtengo wa FRPmsika ukuyembekezeka kufika RMB 38.7 biliyoni (pafupifupi $ 5 biliyoni) pofika 2025, ikukula mpaka RMB 58 biliyoni pofika 2032 (CAGR: 5.97%). M'magawo, mapaipi a epoxy resin mu ntchito zama engineering akuwonetsa kukula kwa 7.2%.
