Cov yam ntxwv ua haujlwm ntawm PPR yeeb nkab

Zoo corrosion kuj: Tsuas yog ob peb oxidants, nws yog resistant rau yaig los ntawm ntau yam tshuaj media, yuav tsis xeb, yuav tsis corrode, yuav tsis yug kab mob, thiab tsis muaj electrochemical corrosion.

Kev ua haujlwm kub zoo: thaum dej ua haujlwm kub yog 70 degree, nws tuaj yeem siv tau ntev, siv lub sijhawm luv luv dej kub txog 95 degree, qhov muag kub yog 140 degree, thiab qhov hnyav yog lub teeb. Qhov ceev yog 0.89 ~ 0.9g / cm3, uas tsuas yog ib feem cuaj ntawm cov yeeb nkab steel thiab ib feem kaum ntawm cov yeeb nkab tooj liab. Vim lub teeb yuag, tus nqi thauj mus los thiab kev tsim kho lub zog ntawm lub installation tuaj yeem txo qis heev.

Hygienic thiab non-toxic: PP-R cov ntaub ntawv yog tag nrho ntawm carbon thiab hydrogen, tsis muaj tshuaj lom hnyav hlau ntsev stabilizer, thiab kev tu cev ntawm cov khoom tau raug kuaj los ntawm lub teb chaws authoritative department.

Lub neej ua haujlwm ntev PPR cov kav dej muaj lub neej ua haujlwm ntau dua 50 xyoo nyob rau hauv qhov ntsuas kub thiab siab.

Cov dej ntws me me: Cov phab ntsa sab hauv ntawm cov yeeb nkab yog du thiab yuav tsis scale. Kev sib txhuam coefficient tsuas yog 0.007, uas yog qis dua li cov kav hlau hlau. Lub peev xwm hla dej yog ntau dua 30 feem pua ​​​​siab dua li cov kav hlau hlau ntawm tib qhov kev qhia tshwj xeeb.

Kev ua haujlwm zoo thermal rwb thaiv tsev: Vim qhov thermal conductivity tsawg ntawm PP-R cov khoom, thermal conductivity ntawm 20 degree yog 0.21 ~ 0.24W / mk, uas yog ntau me dua li cov hlau. cov yeeb nkab, yog li PP-R yeeb nkab muaj kev ua haujlwm zoo thermal rwb thaiv tsev.

Lub zog me me: Vim yog qhov me me elastic modulus ntawm PP-R cov khoom, lub zog nthuav dav tshwm sim los ntawm qhov kub thiab txias hloov me me, thiab nws tsim nyog rau faus ncaj qha thiab zais tso rau hauv cov phab ntsa thiab hauv pem teb.

Kev sib txuas ntawm qhov system yog ruaj khov: PP-R cov kav dej yog txuas nrog kub-kua sib txuas, txuas cov kav dej thiab fittings ntawm tib cov khoom rau hauv tag nrho, thiab tensile, dabtsi yog khoov thiab cuam tshuam lub zog ntawm lub interface yog siab dua lub zog ntawm cov yeeb nkab lub cev, yog li tiv thaiv cov dej xau txaus ntshai.
