1, tsis muaj kuab lom, huv. PP-R raw khoom yog polyolefin, uas muaj tsuas carbon thiab hydrogen ntsiab, non-toxic, sanitary, txhim khu kev qha zoo. PP-R hauv raw khoom tsim, khoom ua, siv thiab pov tseg ntawm tag nrho cov txheej txheem yuav tsis cuam tshuam rau tib neeg lub cev thiab ib puag ncig, lub npe hu ua ntsuab tsev cov ntaub ntawv. Cov khoom yuav siv tsis tas rau cov dej kub thiab txias dej, tab sis kuj yog rau cov dej lim huv.
2, kev txuag hluav taws xob. Qhov kub siab tshaj plaws yog 95 degrees, thiab qhov siv ntev npaum cas yog 75 degrees, uas tuaj yeem siv cov dej kub dej uas muaj nyob rau hauv qhov kev tsim cov dej hauv tsev thiab kua tsim. Vim tias cov thermal conductivity ntawm cov khoom yog 0.21W / m degrees, tsuas yog 1/200 ntawm cov thermal conductivity ntawm cov yeeb nkab, yog li nws muaj cua kub zoo dua, siv hauv dej kub thiab cua sov, yuav txuag tau ntau lub zog .
3, kev tawm kev tiv thaiv, kev ua haujlwm hnyav, tsis nti. Kev siv PP-R yeeb nkab thiab fittings yuav zam tau cov yeeb nkab fouling thiab clogging, thiab txhawj txog cov kab xeb hauv lub dab da dej. Sab hauv thiab txheej phab ntsa yog cov tsoog thiab du, qhov kev ua haujlwm tsis kam yog me me, xim yog muag, thiab qhov zoo li zoo nkauj.
4. Tiv thaiv kom khov dawb. Qhov zoo tshaj plaws ntawm PP-R ua rau hauv koog ntawm lub raj xa nrog cov kua ntub dej txias, thiaj li nqus tau qhov ntim ntawm qhov te poob hnyav kom tsis muaj qhov nrawm dua.
5, lub cev nyhav, siab zog. Qhov kev faib ua feem ntawm PP-R thiab cov fittings yog tsuas yog 1/8 ntawm cov pob zeb zoo tib yam, thiab lub zog ntawm qhov kev ntsuam xyuas siab yog mus txog 5MPa (50kg / cm2), thiab lub siab tawv yog qhov zoo thiab qhov kev ua haujlwm tsis zoo.
6, yooj yim rau nruab thiab txhim khu kev qha. Qhov kub kub ntawm kev sib txuas ntawm PP-R yeeb nkab thiab yeeb nkab fittings tuaj yeem ua tiav hauv ob peb feeb los yog kaum tawm vib nas this los ntawm cov cuab yeej tshwj xeeb. Lub zog ntawm kev sib txuas ntawm cov kav dej thiab fittings txuas los ntawm kub yaj yog ntau dua li lub zog ntawm cov yeeb nkab nws tus kheej. Qhov tshwj xeeb ntawm PP-R yeeb nkab kub lub qhov kev sib txuas yog qhov ua kom tsis sib haum, kev ywj ywj thiab cov khoom siv sib txuas ntawm tus nqi qis, kev kub ceev, kev lag luam yooj yim, kev nyab xeeb thiab txhim khu kev qha, tshwj xeeb tshaj yog rau kev cog lus faus concealed, tsis hais txog seb txoj kev xa mus cov txheej txheem ntawm kev siv mus sij hawm ntev. Nws muaj kev nyab xeeb thiab txhim khu kev txuas mus nrog yeeb nkab hlau thiab dej siv thiab txais yuav zoo tooj hlau ntxig.
7, lub neej ntev kev noj haus: raj dej cij raws li kev ua haujlwm ntawm 50-100 xyoo.
