Cov txiaj ntsig ntawm kev siv PPR rwb thaiv tsev cov kav dej tuaj yeem raug suav hais tias yog "kev txuag hluav taws xob, ua haujlwm ntev, txuag nyiaj, thiab txuag kev txhawj xeeb". Ua ntej tshaj plaws, nws cov txiaj ntsig tseem ceeb nyob hauv nws qhov kev ua tau zoo thermal rwb thaiv tsev: PPR cov khoom nws tus kheej muaj cov thermal conductivity tsawg heev. Thaum ua ke nrog polyurethane los yog polyethylene kaw- cell foam rwb thaiv tsev txheej, tshav kub poob yog txo los ntawm 5 mus rau 8 npaug piv nrog cov tsoos hlau kav, uas yuav txo tau lub zog pov tseg thiab txuag tau ntau ntawm cov nqi cua sov nyob rau hauv lub sij hawm ntev. Qhov thib ob, lawv muaj kev ruaj khov thiab txhim khu kev qha thiab muaj cov nqi kho mob qis heev: PPR kav dej yog corrosion-resistant, tsis yog- scaling, thiab yuav tsis xeb los yog thaiv los ntawm nplai zoo li steel kav. Ua ke nrog prefabricated ib - txheej txheem molding, lawv tuaj yeem muab faus lossis submerged hauv dej. Cov txheej txheem tsim lub neej ntev li 30 txog 50 xyoo, uas yuav luag tsis xav tau kev saib xyuas. Tsis tas li ntawd, kev teeb tsa yooj yim thiab ua haujlwm tau zoo: PPR cov kav dej rwb thaiv tsev tsuas yog ib qho -yim qhov hnyav ntawm cov kav hlau thiab tsis tas yuav loj- nplai lifting khoom; lawv yog kub-kua txuas, nrog kev sib txuas ruaj khov thiab tsis muaj dej; lub Hoobkas- txheej rwb thaiv tsev prefabricated tshem tawm ntawm - txheej txheem wrapping, uas tuaj yeem txo lub sijhawm tsim kho thiab txuag nqi zog. Thaum kawg, nws yog ntsuab thiab ib puag ncig tus phooj ywg: PPR cov ntaub ntawv tsis yog - lom thiab huv si, tsis cuam tshuam rau cov dej zoo, muaj kev siv hluav taws xob tsawg hauv cov txheej txheem tsim khoom, thiab tuaj yeem rov ua dua. Muab ua ke, PPR rwb thaiv tsev kav yog tshwj xeeb tshaj yog haum rau cov xwm txheej uas ntev -vim qhov yuav tsum tau rwb thaiv tsev xws li cua sov hauv nruab nrab cov yeeb nkab txuas, nruab nrab cua txias, thiab dej kub hauv tsev. Lawv yog ib qho kev xaiv pheej yig thiab txhim khu kev qha rau cov tsev niaj hnub kom ua tiav lub zog ua haujlwm siab thiab txo cov nqi ntawm lub neej.
