PPR YEEBCov Lus Qhia Tu: Cov Ntawv Qhia Kws Tshaj Lij rau Kev Ua Haujlwm Zoo
PPR (Polypropylene Random Copolymer) Cov kav dej tau siv nyob rau hauv cov kav dej {} Txawm li cas los xij, kev txhim kho tsis zoo, lossis cov kab mob tsis txaus ntseeg, lossis cov kab mob tsis txaus ntseeg, lossis cov kab mob tsis muaj txiaj ntsig}}Ua tau zoo, cov lus qhia rov qabtxhawm rau tswj ppr kaves zoo .
1. Thaum los ntxuavPP cov kav dej
Kev tu kom zoo yog pom zoo hauv cov xwm txheej no:
Npaj Ua Ntej: Tshem tawm cov khoom lag luam seem (e {{{0} g ., roj, plua plav).
Kev-teeb tsa (commissioning): Yaug tawm cov khib nyiab los ntawm vuam / txiav .
Lub sijhawm txij nkawm: Txhua txhua 3-5 xyoos rau cov tshuab nyob hauv tsev; ib xyoos ib zaug rau kev lag luam / kev siv siab siv .
Cov Teeb Meem: Tsis tshua txaus ntws, cov dej ntws tawm, lossis okors .
2.} theem-ib-kauj ruam ntxuav txoj kev
{.} Ua ntej-Installation Tu
So nrog isopropyl cawv (70%)
Siv daim ntaub pub dawb kom tshem cov roj los ntawm kev txiav cov npoo lossis welded pob qij txha .
Zam acetone-nws tuaj yeem txwv PPR sijhawm dhau lub sijhawm .
Kev nqus cua tshuab cua tshuab
Siv 4-6 bar cua siab rau dislodge plua plav los ntawm cov yeeb nkab interiors {}}
Kev Nyab Xeeb Kev Nyab Xeeb: Hnav kev tiv thaiv qhov muag kom tiv thaiv cov khib nyiab pov tseg {}}
B .} post-installation flushing
Pib yaug nrog dej huv
Khiav dej potable ntawm tag nrho Flow rau 10-15 feeb kom tshem tawm vuam khib nyiab .
Tshuaj Yaum Tshuaj (rau cov kev paug hnyav)
Kev siv1-2% citric acid daws(Tsis muaj tshuaj lom, cov zaub mov-muaj kev nyab xeeb) rau 1-2 teev kom tshem tawm cov nplai {}}
Yaug kom huv si nrog dej tshiab los tiv thaiv cov kua qaub seem .
C . kev txij nkawm ntev
NEEG KHO TSHUAB TXHAIS (RAU COV THAIV HAIV NEEG)
Siv aYEEB TU TXHUAM(Nylon bristles, txoj kab uas hla qis dua lossis sib npaug ntawm 90% ntawm cov yeeb nkab ID) kom txhuam cov interiors .
Zam kev txhuam cov hlau-lawv tuaj yeem kos PPR thiab txhawb txoj kev loj hlob biofilm .
UV Kab Mob (Yeem)
Rau kaw-lub tshuab kaw (e {.}}}}}}}, nruab UV Sterilizers mus tua cov kab mob tsis muaj tshuaj lom neeg.

Siv cov tshuaj chlorine-raws li cov tshuaj ntxuav: PPR is sensitive to chlorine >50PPP-nws ua rau emgrittlement .
❌ High-Pressure Water Jetting (>10 bar): Tuaj yeem deformic yeeb nkab phab ntsa lossis dislodge fittings .
❌ Skipping rinsing tom qab ntxuav tu: Acid residacte nrawm hauv cov khoom siv hlau .
{{0 {{}} Thaum twg los hloov vs . huv
Huv yog:
Cov me nplai tsim (tsawg dua lossis sib npaug rau 1 hli thickness) .
Txo kev khiav tawm ib ntus .
Hloov yog:
Cov kab nrib pleb, sib sib zog nqus khawb, lossis tshem tawm .

7. Cov lus pom zoo
Rau cov tshuab nyob: Huv si txhua 5 xyoo nrog citric acid .
Rau Kev Muaj Tshuab: Nruab inline lim thiab yaug peb lub hlis twg .
Rau geothermal / Hnub Ci loops: Siv Glycol-Ntau Cov tshuaj ntxuav (e {{1} g {}, propylene glycol-based daws) .
