PPR tube, tseem hu ua peb hom polypropylene raj thiab kuj hu ua polyol copper polymer polypropylene tub lossis PPR yeeb nkab, dav siv hauv tsev tsim dej thiab faj siv dej, tu dej thiab tu dej, dej taws, kiag, industrial thiab ua liaj teb. PPR raj nrog roj copolymer polypropylene extruded rau hauv yeeb nkab, txhaj tshuaj rau hauv yeeb nkab.
Thawj kev noj qab haus huv, tsis muaj kuab lom: Cov khoom no yog khoom ntsuab, tuaj yeem siv rau cov dej ntshiab haus yeeb nkab.
Qhov kub thib ob ua haujlwm zoo: cov dej kub ua haujlwm yog 95 ℃, siv lub sijhawm kub li 120 degrees Celsius, ntawm qhov kub siab tshaj 60 degrees Celsius thiab kev ua haujlwm siab ntawm 1.2Mpa raws li cov kev siv rau kev siv mus sij hawm ntev.
Qhov kev tiv thaiv tsis tau qhov teeb meem thib peb, feem ntau yog cov pob txha nyob hauv cov dej thiab cov vaj tse hauv cov chemicals tsis yog tshuaj lom neeg, tsis xeb, tsis muaj corrosion, tsis muaj tus kab mob qe. Yuav tsum tau zam ntawm cov raj xa dej thiab dej phwj, ntxhua khaub ncaws ntxhuav macadamus xeb txhawj xeeb (qee qhov kav dej uas yog daim npog tua kab mob, uas yog lub tswv yim ntawm speculation, PPR cov ntaub ntawv zoo tiag tiag yog nws qhov kev ua tau zoo).
Qhov nyhav plaub yog lub teeb, siab zog, zoo toughness: ntom 0.89-0.91g / cm3, tsuas yog ib-cuaj caum ntawm cov yeeb nkab, kaum tawm ntawm lub raj raj, kev sim siab siab zog txog li 5.0Mpa saum toj siab (50kg / Cm ) saum toj no, zoo toughness, tej yam ua hauj.
Thib thermal thermal rwb thaiv: 20 ℃ thaum lub thermal conductivity ntawm 0.23-0.24W / mk, dua li cov yeeb nkab (43-52W / mk), tooj liab (333W / mk), tsuas yog ib puas feem pua ntawm cov hlau yeeb, rwb thaiv tsev txuag cov nyhuv yog zoo heev.
Thib rau cov yeeb nkab yog me me: cov phab ntsa ntawm cov yeeb nkab, tsis txhuam, cov phab ntsa coefficient tsuas yog 0.007, ntau qis dua cov hlau yeeb.
Xya lub yooj yim thiab txhim khu kev qha: Raws li cov polypropylene muaj kev kub thermal fusion kev ua tau zoo, qhov kub hlau txuas yuav ua los ntawm tib cov khoom yeeb nkab thiab cov yeeb nkab fittings txuas nrog tag nrho. Tsis tas yuav tsum muab hlua khi, ob peb vib nas this los ua kom tiav ib qho taub hau kev txuas, thiab cov kav dej thiab cov kav dej sib txuas nrog cov nickel-plated copper inserts, kev ruaj ntseg thiab txhim khu kev qha, muab xaus rau cov kev piam sij ntawm dej ntub.
Yim zoo nkauj tsos: cov khoom phab ntsa yog du, dej tsis kam yog me me, mos xim, zoo nkauj zoo nraug.
Lub Cuaj Hli Luv Kev Ua Haujlwm: lub raj xa dej hauv lub neej zoo li 50 - 100 xyoo.
