Nyob rau hauv cov ntsiab lus ntawm cov kav dej, "PB" sawv rau polybutene. Nws yog hom siab - kev ua tau cov khoom siv thermoplastic. Nov yog qee qhov ntawm nws cov yam ntxwv tseem ceeb thiab vim li cas nws tau siv hauv cov yeeb nkab raug:
Ua kom durability: PBes muaj kev tiv thaiv zoo heev rau tshuaj corrosion. Lawv tuaj yeem tiv thaiv kev raug rau ntau yam tshuaj, ua rau lawv haum rau kev siv hauv cov kav dej muaj kev lag luam uas cov dej thauj khoom yuav ua kom xeb. Piv txwv li, hauv cov nroj tsuag tshuaj, PBES tuaj yeem siv tau los piav cov tshuaj acidic lossis alkaline yam tsis muaj kev puas yooj yim.
Kev kub siab - kub tsis kam: PBES tuaj yeem tswj hwm lawv cov qauv kev ntseeg siab thiab kev ua tau zoo nyob rau hauv cov kub siab. Cov cuab yeej no ua rau lawv zoo tshaj plaws rau kev thov xws li cov tshuab dej kub hauv tsev. Lawv tuaj yeem ua rau cov dej kub uas tsis ua kom sov lossis deforming, ua kom ntev - ntev thiab txhim khu kev qha.
Yooj taus: PB cov kav yog hloov tau yooj yim heev. Qhov hloov tau yooj yim dua cov txheej txheem teeb tsa, tshwj xeeb tshaj yog cov piping txheej txheem. Lawv tuaj yeem yooj yim khoov li ntawm cov nyom thaum lub sijhawm teeb tsa, txo qhov kev xav tau rau cov fittings ntxiv thiab pob qij txha. Nyob rau hauv cov kav dej uas muaj cov kav dej, piv txwv li, PB kav tuaj yeem khoov tau kom haum nyob ib ncig ntawm phab ntsa, cov plag tsev, thiab lwm yam txheej txheem txheej txheem.
Ntev - Kev Ua Haujlwm: Nrog lub neej muaj kev pabcuam ntev, PBes muab nqi - ua hauj lwm zoo nyob rau hauv lub sijhawm ntev. Lawv yuav tsum tau hloov dua tshiab piv rau qee lwm cov kav dej, uas txo cov nqi kho thiab hloov tus nqi dhau sijhawm. Nyob rau hauv loj - nplai infrastrastrastrastrastrastrastrastrastrastrastrastrastrastrastrastrasure tej yaamtom zoo li koog tsev kawm ntawv cua sov, lub sijhawm ntev ntawm PBES tuaj yeem pab txhawb kev ruaj khov thiab tus nqi - ua haujlwm ntawm lub system.
