Qhov laj thawj yog vim li cas FRP (fiberglass reinforced yas) yeeb nkab fittings tuaj yeem hloov qee cov yeeb nkab hlau fittings hauv ntau daim ntawv thov yog vim lawv cov yam ntxwv ntawm kev ua tau zoo.
Corrosion kuj yog ib qho ntawm nws cov txiaj ntsig tseem ceeb tshaj plaws, txaus siab rau cov neeg siv khoom. Siv cov thermosetting resin raws li matrix, FRP yeeb nkab fittings muaj kev tiv thaiv zoo rau ntau yam tshuaj lom neeg xws li acids, alkalis, thiab ntsev, ua rau lawv tshwj xeeb tshaj yog tsim nyog rau kev xa cov kua dej corrosive los yog ua haujlwm hauv cov av hnyav thiab huab cua. Piv nrog rau qee cov ntaub ntawv hlau, lawv yuav tsum tau siv tshuaj tiv thaiv tsis tshua muaj - kev tiv thaiv corrosion, ua rau lub neej ua haujlwm ntev dua.
Lub teeb yuag thiab siab -lub zog yog lwm qhov tseem ceeb. Qhov ntom ntawm FRP cov ntaub ntawv yog qis dua li cov hlau xws li hlau thiab cam khwb cia hlau, kwv yees li ntawm ib qho -quarter ntawm hlau. Qhov no ua rau kev thauj mus los, tuav, thiab ntawm - qhov chaw teeb tsa yooj yim dua thiab ua haujlwm tsawg dua - hnyav. Nws lub zog tshwj xeeb (lub zog rau qhov sib piv) yog nyob ze lossis ntau tshaj li ntawm cov pa roj carbon zoo tib yam, thiab nws cov khoom siv kho tshuab ua tau raws li qhov xav tau ntawm cov haujlwm engineering feem ntau.
Lwm qhov zoo muaj xws li cov yam ntxwv zoo hydraulic. Lub phab ntsa du ntawm FRP yeeb nkab fittings ua rau muaj kev sib txhuam tsis zoo thiab tsis tshua muaj kev loj hlob ntawm cov kab mob microbial, yog li ua rau qis zog noj thaum xa cov kua dej thiab ntev dua - kev lag luam kev lag luam. Nws kuj muaj cov khoom siv rwb thaiv tsev zoo (tsis yog-cov khoom siv hluav taws xob thiab tsis yog-thermal), qee qhov kev tsim qauv yooj yim (cov ntaub ntawv tsim thiab cov qauv tsim tuaj yeem hloov kho raws li xav tau), thiab lub neej ua haujlwm ntev.
Tau kawg, txhua yam khoom muaj nws qhov kev siv ntau yam. Fiberglass yeeb nkab fittings kuj muaj qee qhov kev txwv, xws li lawv qhov tawv nqaij feem ntau qis dua li cov kav hlau, lawv muaj kev nkag siab ntau dua rau cov hluav taws xob ultraviolet (yuav tsum tau ntxiv cov UV stabilizers lossis cov txheej txheej saum npoo los txhim kho qhov no), thiab lawv qhov siab - qhov kub thiab txias kuj muaj qee qhov txwv siab; Feem ntau, qhov ntev - lub sijhawm ua haujlwm kub yuav tsum tsis pub tshaj qhov txwv (nyob ntawm qhov system resin).
