FRP chitoliro luso muyezo kupanga mphamvu

Timagwira ntchito limodzi ndi mabungwe ambiri a International Standards Organisation (ISO), European Standards (EN), British Standard Institute (BSI), Deutsches Institut für Normung (DIN), American Society for Testing and Material (ASTM), American Society of Mechanical Engineers (ASME), American Water Works Association (AWWA) ndi American Petroleum Institute (API) kuti mosalekeza kupititsa patsogolo ntchito zamapaipi athu ophatikizika ndikuwonetsetsa kuti tikutsatira mosamalitsa machitidwe ndi miyezo yabwino yamakampani.

Ukadaulo wathu wopitilira muyeso wokhotakhota umatsimikiziridwa kwambiri pamakampani opanga chitoliro.Mipope amapangidwa pa makina mosalekeza filament mapiringidzo.Makinawa amakhala ndi mandrel opangidwa ndi gulu la helical bala mosalekeza zitsulo, zothandizidwa ndi matabwa omwe amapanga mawonekedwe a cylindrical.Monga mandrel opangidwa amatembenukira kumapanga khoma lamitundu yosiyanasiyana la makulidwe ofunikira.

The mosalekeza mapiringidzo ndondomeko kumatithandiza kupanga mapaipi ndi diameters mpaka DN 4000 mm.

Mipope amapangidwa pogwiritsa ntchito helical (reciprocal) filament mapindikidwe ndondomeko imene impregnated magalasi CHIKWANGWANI reinforcement ndi utomoni ndi ntchito pa mwatsatanetsatane zitsulo mandrel mu ndondomeko yolembedwa.Kugwiritsa ntchito mobwerezabwereza ulusi wonyowa kumapangitsa kuti pakhale khoma lamitundu ingapo la makulidwe ofunikira.

The helical mapiringidzo ndondomeko kumatithandiza kupanga mapaipi ndi diameters mpaka DN 1600 mm.

Zigawo za Zinthu ZophatikizikaKusankha kwa fiber nthawi zambiri kumayang'anira mawonekedwe azinthu zophatikizika.Mpweya, Galasi, ndi Aramid ndi mitundu itatu ikuluikulu ya ulusi yomwe imagwiritsidwa ntchito pomanga.Chophatikizikacho nthawi zambiri chimatchulidwa ndi ulusi wolimbitsa, mwachitsanzo, CFRP wa Carbon Fiber Reinforced Polymer.Zofunika kwambiri zomwe zimasiyana pakati pa mitundu ya ulusi ndi kuuma komanso kupsinjika.

Mitundu ya Fiber Reinforced Polymer (FRP)
1. Glass Fiber Reinforced Polymer (GFRP)
Ulusi wagalasi umapangidwa posakaniza mchenga wa silika, miyala yamchere, folic acid ndi zinthu zina zazing'ono.Kusakaniza kumatenthedwa mpaka kusungunuka pafupifupi 1260 ° C.
Galasi losungunukalo limaloledwa kuyenda m'mabowo abwino a platinamu.Zingwe zamagalasi zimakhazikika, zimasonkhanitsidwa ndikuvulala.Ulusi umakokedwa kuti uwonjezere mphamvu yolowera.Kenako ulusiwo amalukidwa m’njira zosiyanasiyana kuti agwiritse ntchito popanga zinthu zosiyanasiyana.

Kutengera kapangidwe ka aluminium laimu borosilicate, magalasi opangidwa ndi magalasi amaonedwa kuti ndi omwe amalimbitsa kwambiri ma polymer matrix composites chifukwa champhamvu zawo zotchingira magetsi, kutsika kwa chinyezi komanso mawonekedwe apamwamba amakina.

Galasi nthawi zambiri imakhala yabwino yosamva fiber koma imalemera kuposa mpweya kapena aramid.Ulusi wagalasi uli ndi mikhalidwe yabwino kwambiri yofanana kapena yabwinoko kuposa chitsulo mumitundu ina.
