Cov yam ntxwv ua haujlwm ntawm PPR Pipes

1. Zoo corrosion kuj: Tsuas yog ob peb oxidants, nws tuaj yeem tiv taus qhov yaig ntawm ntau yam tshuaj lom neeg. Nws yuav tsis xeb, corrode, yug kab mob, thiab tsis muaj electrochemical corrosion.
2. Kev ua haujlwm kub zoo: thaum dej ua haujlwm kub yog 70 degree, nws tuaj yeem siv tau ntev, dej kub nce mus txog 95 degree rau kev siv sijhawm luv, thiab qhov muag kub yog 14{{7. }} degree. Nws yog lub teeb yuag. Qhov ceev yog 0.89 ~ 0.9g / cm3, uas tsuas yog ib feem cuaj ntawm cov kav hlau thiab ib feem kaum ntawm cov kav hlau. Vim nws lub teeb yuag, cov nqi tsheb thauj mus los thiab kev tsim kho siv zog tuaj yeem txo qis heev.
3. Hygienic thiab non-toxic: PP-R cov khoom yog tag nrho ntawm carbon thiab hydrogen ntsiab. Tsis muaj tshuaj lom hnyav hlau ntsev stabilizers ntxiv. Kev tu cev ntawm cov khoom siv tau raug sim los ntawm lub tebchaws muaj cai tswj hwm.
Lub neej ua haujlwm ntev: PPR kav dej muaj lub neej ua haujlwm ntawm ntau tshaj 50 xyoo nyob rau hauv qhov ntsuas kub thiab kev kub ntxhov.
4. Cov dej ntws me me: Sab hauv phab ntsa ntawm cov yeeb nkab yog du thiab yuav tsis nplai. Kev sib txhuam coefficient tsuas yog 0.007, uas yog qis dua li cov kav hlau. Cov dej ntws muaj peev xwm ntau dua 30% siab dua li cov kav hlau hlau ntawm tib qhov tshwj xeeb.
5. Kev ua haujlwm zoo thermal rwb thaiv tsev: Vim tias qhov thermal conductivity tsawg ntawm PP-R cov khoom, thermal conductivity coefficient ntawm 20 degree yog 0.21 ~ 0.24W / mk, uas yog ntau me dua. uas yog cov yeeb nkab steel, yog li PP-R kav dej muaj cov thermal rwb thaiv tsev zoo.
6. Me me expansion quab yuam: Txij li cov elastic modulus ntawm PP-R cov khoom yog me me, lub expansion quab yuam tshwm sim los ntawm kub hloov me me, yog li nws yog haum rau faus ncaj qha thiab zais daim ntawv thov nyob rau hauv cov phab ntsa thiab pem teb nto.
7. Lub kaw lus ruaj khov: PP-R cov kav dej yog txuas nrog kub-kua sib txuas, uas txuas cov kav dej thiab cov yeeb nkab fittings ntawm tib cov khoom mus rau hauv tag nrho. Lub tensile, dabtsi yog khoov thiab cuam tshuam lub zog ntawm lub interface yog siab dua lub zog ntawm cov yeeb nkab nws tus kheej, yog li tiv thaiv kom txhob muaj kev pheej hmoo ntawm dej to.
