Lub durability ntawm PPSU yeeb nkab fittings yog qhov zoo ntawm tib cov kav dej. Ntau tus neeg muas zaub yuav xav txog qhov kav ntev ntawm cov kav dej thaum yuav cov kav dej, vim hais tias cov kav dej zoo li no yuav siv tau ntev rau yav tom ntej, tshwj xeeb tshaj yog rau qee qhov kev kho kom zoo nkauj, cov kav dej muaj zog, ruaj khov dua qib, tsis muaj kev txhawj xeeb tom qab. Tom qab siv lub sijhawm ntev ntawm PPSU yeeb nkab fittings, tsis muaj cov neeg siv khoom teb rau kev tawg thiab kev laus loj. Hauv qab no yog qee cov lus nug uas nquag nug txog cov kav dej kav ntev. Cracking: Yog tias qhov hardness ntawm cov yeeb nkab nws tus kheej tsis txaus, los yog muaj teeb meem nrog cov khoom siv raw, nws yuav ntsib qhov teeb meem ntawm kev tawg tom qab siv sijhawm. Yog tias cov yeeb nkab tawg lawm, nws yuav tsum tau hloov lub sijhawm, txwv tsis pub yuav muaj cua nkag lossis dej ntws tawm. Kev laus: Cov kav dej laus muaj ntau heev. Qee cov kav dej tsis zoo, thiab cov teeb meem kev laus tshwm sim tom qab lub sijhawm ntev. Tom qab kev laus, yog tias nws tsis ntsib teeb meem xws li kev kub siab thiab tsis muaj kev cuam tshuam sab nraud, nws tuaj yeem txuas ntxiv mus rau lub sijhawm. Yog tias nws ntsib cov teeb meem saum toj no, nws yuav ncaj qha tawg. Fracture: Cov pob txha tawg yog qhov hnyav dua li ob qhov kev sib piv saum toj no, thiab qee cov kav dej tau tawg ncaj qha, ua rau cov pa tawm thiab dej tawm.
Vim li cas cov kav ntev ntawm PPSU fittings siab heev? Cov khoom siv raw nws tus kheej muaj qhov ruaj khov, thiab ruaj khov rau qee cov kua qaub, alkalis, ntsev, cawv, aliphatic hydrocarbons, thiab lwm yam. Ib nrab soluble hauv ester ketone aromatics, soluble hauv halocarbon `DM. Zoo rigidity thiab toughness, kub tsis kam, thermal oxidation tsis kam, zoo heev creep kuj, corrosion kuj ntawm inorganic acid, alkali, ntsev tov, ion hluav taws xob kuj, non-toxic, zoo rwb thaiv tsev thiab nws tus kheej-extinguishing, yooj yim rau cov duab thiab txheej txheem. Cov txiaj ntsig no ncaj qha txiav txim siab tom qab siv cov yeeb nkab fittings.
