In today's life, there are all kinds of pipes all around us, which can ensure the normal progress of our life, so people attach great importance to the pipe material. Everyone should know the ppr material, and its application in life can be said to be the most important. Extensive, but do you know what characteristics of it are worthy of our trust? I believe that there should be not many people who know it, then let's learn the characteristics of ppr plastic pipes together, so that we can use it more practically to guarantee Life.
Qhov tseeb, hom yeeb nkab no muaj ntau yam ntxwv. Nws yog qhov sib zog dua li cov ntaub ntawv yas zoo tib yam thiab muaj zog corrosion kuj, yog li nws cov kev pab cuam lub neej ntev dua li cov kav dej zoo tib yam. Kev tsom xam tshwj xeeb yog nyob ntawm cov lus qhia hauv qab no.
Ua ntej tshaj plaws, nws muaj kev nyab xeeb heev thiab tsis yog - lom. Lub npe scientific ntawm ppr yog polyolefin. Nws muaj cov ntsiab lus carbon thiab hydrogen, thiab tsuas muaj ob qho no, yog li nws muaj kev nyab xeeb thiab txhim khu kev qha, thiab yuav tsis muaj teeb meem kev noj qab haus huv. Tsis muaj kev hem thawj, thiab nws yog cov khoom siv hauv tsev ntsuab. Cov khoom siv tsis yog- tshuaj lom thiab tu cev no muaj ntau yam kev siv, txawm tias nws yog lub tshuab dej txias thiab dej kub lossis cov dej ntshiab.
Raws li peb txhua tus paub, nyob rau hauv cov dej kub siv nyob rau tib lub sij hawm, qhov yuav tsum tau rau cov kav dej yog siab heev, thiab lub tshav kub tsis kam thiab thermal rwb thaiv tsev los ntawm ppr yas kav yog zoo heev, lub siab tshaj plaws kev khiav hauj lwm kub yog 95 degree, thiab lub thermal conductivity ntawm cov khoom no yog qis dua li cov kav hlau zoo tib yam, yog li nws tuaj yeem ua tau zoo insulated, thiab nws tuaj yeem txuag tau ntau lub zog thaum siv dej kub thiab cua sov.
Qhov tseem ceeb tshaj plaws ntawm cov kav dej yog qhov teeb meem kev sib txuas, thiab kev sib txuas ntawm cov kav dej ppr tsis yog tsuas yog txhim khu kev qha, tab sis kuj yooj yim heev. Tsis tas li ntawd, txoj kev sib txuas no coj tau zoo heev rau qhov kev sib txuas. Piv nrog rau lwm cov kav dej, txoj kev no yog qhov ua tau zoo heev.
Txhua yam ntawm cov kav dej yuav tsum muaj kev tiv thaiv corrosion zoo heev, thiab cov khoom siv steel yeeb nkab tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, ppr yeeb nkab tuaj yeem ua rau qhov tsis txaus no, nws tuaj yeem tiv taus tus nqi pH ntawm 1 txog 14 hauv qhov kub thiab txias. concentration ntawm acid thiab alkali corrosion, thiab sab hauv phab ntsa ntawm cov yeeb nkab yog du heev, nws yuav tsis scale, uas yuav ua rau kom cov kua xa tuaj.
Lub elasticity ntawm ppr yas yeeb nkab kuj zoo heev. Qhov kev ua haujlwm tshwj xeeb no tuaj yeem ua kom ntseeg tau tias nws tuaj yeem tiv thaiv kom khov thiab tawg, thiab cov yeeb nkab no tuaj yeem rov ua dua tshiab, uas tseem ceeb heev. Cov khib nyiab rov qab tuaj yeem ua tiav thiab tom qab ntawd siv rau kev tsim khoom. Cov yeeb nkab yog ib puag ncig zoo heev.
