Cov xim ntawm cov yeeb nkab hlau cam khwb cia thiab cov kev cai tshwj xeeb ntawm kev lag luam

Xim ntawmcov kav hlau cam khwb ciaFeem ntau yog hais txog lawv siv, kev kho kom tsis txhob xeb lossis cov qauv kev lag luam. Cov teb chaws thiab cov lag luam sib txawv yuav muaj cov kev cai tshwj xeeb rau cov xim kom ntseeg tau tias muaj kev nyab xeeb, tiv thaiv xeb lossis yooj yim txheeb xyuas. Cov hauv qab no yog kev faib tawm ntxaws ntxaws:

·Xiav/Dej siv hauv kev lag luam, cua compressed/Hoobkas, lub tshuab cua compressed

·Xim daj/Cov kav dej roj (tsawg dua cov hlau cam khwb cia, feem ntau yog cov kav hlau)/Kev xa roj (qee thaj chaw tseem siv hlau cam khwb cia)

·Nyiaj/Kev kho mob galvanized tiv thaiv xeb/Sab nraum zoov, ib puag ncig noo noo, qhov yuav tsum tau ua kom tsis txhob xeb

2. Cov kev cai tshwj xeeb rau cov xim yeeb nkab hlau hauv kev lag luam hauv tsev thiab txawv teb chaws 

(1) Kev ua lag luam Suav teb (GB tus qauv)

Cov Kav Dej Hlau Uas Ua Los Ntawm Cov Hlau: feem ntau yog xim dub (asphalt tiv thaiv xeb) lossis xim grey hlau qub, ib feem coated nrog epoxy resin (ntsuab).

Cov Yeeb Nkab Hlau Uas Muab Dej:Cov yeeb nkab hlau cam khwb cia ib txwm muaj: dub lossis liab (rau kev tiv thaiv hluav taws).

Cov Yeeb Nkab Hlau Ductile (DN80-DN2600): phab ntsa sab nraud txau nrog zinc + asphalt (dub), sab hauv nrog cement lossis epoxy resin (grey / ntsuab).

Cov Yeeb Nkab Tiv Thaiv Hluav Taws: txheej liab, ua raws li cov lus qhia tiv thaiv hluav taws ntawm GB 50261-2017.

Cov Yeeb Nkab Roj: daj (tab sis cov yeeb nkab roj niaj hnub no feem ntau yog ua los ntawm PE lossis cov yeeb nkab hlau, thiab cov hlau cam khwb tsis tshua siv).

(2) Kev ua lag luam hauv Tebchaws Meskas (AWWA/ANSI Standard)

AWWA C151 (cov yeeb nkab hlau ductile):
Phab ntsa sab nraud: feem ntau yog dub (txheej txheej asphalt) lossis nyiaj (galvanized).
Sab hauv: cement mortar (grey) los yog epoxy resin (ntsuab/xiav).

Cov Yeeb Nkab Tiv Thaiv Hluav Taws (NFPA tus qauv): lub logo liab, qee qhov yuav tsum tau muaj cov lus "FIRE SERVICE" luam tawm.

Cov Yeeb Nkab Dej Haus (NSF/ANSI 61 daim ntawv pov thawj): sab hauv yuav tsum ua tau raws li cov qauv kev huv, tsis muaj qhov yuav tsum tau ua rau xim phab ntsa sab nraud, tab sis feem ntau siv lub logo ntsuab lossis xiav.

(3) European lag luam (EN txuj)

TS EN 545 / EN 598 / EN 598 Cov yeeb nkab hlau yeeb nkab

Sab Nraud Anticorrosion: zinc + asphalt (dub) lossis polyurethane (ntsuab).

Sab Hauv: cement mortar lossis epoxy resin, tsis muaj cov cai xim nruj, tab sis yuav tsum ua raws li cov qauv dej haus (xws li daim ntawv pov thawj KTW).

Cov Yeeb Nkab Hluav Taws: liab (qee lub tebchaws yuav tsum tau luam tawm "FEUER" lossis "FIRE").

Cov Yeeb Nkab Lag Luam: tej zaum yuav yog xiav (cua compressed) lossis daj (roj, tab sis cov yeeb nkab hlau cam khwb cia tau hloov maj mam).

(4) Japanese lag luam (JIS tus qauv)

JIS G5526 (cov yeeb nkab hlau ductile): Phab ntsa sab nraud feem ntau yog xim dub (asphalt) lossis galvanized (nyiaj), thiab sab hauv yog cement lossis resin.

Cov yeeb nkab hluav taws: pleev xim liab, qee qhov yuav tsum tau luam tawm "kev tua hluav taws".

Cov yeeb nkab dej haus: xim ntsuab lossis xiav, ua raws li tus qauv JHPA.

3. Qhov cuam tshuam ntawm cov xim ntawm cov txheej txheem tiv thaiv xeb tshwj xeeb

Epoxy resin txheej: feem ntau yog ntsuab lossis xiav, siv rau cov kev xav tau siab tiv thaiv xeb (xws li dej hiav txwv, kev lag luam tshuaj lom neeg).
Txheej Polyurethane: tej zaum yuav ntsuab, dub lossis daj, nrog rau kev tiv taus huab cua zoo.
Txheej zinc + asphalt: phab ntsa sab nraud dub, tsim nyog rau cov kav dej faus.

4. Cov Lus Qhia Tseem Ceeb: Yuav ua li cas xaiv cov xim ntawm cov kav dej hlau cam khwb cia?

Xaiv los ntawm kev siv:
Cov dej ntws/dej phwj → dub/grey
Dej haus → ntsuab/xiav
Kev tua hluav taws → liab
Kev lag luam → los ntawm kev txheeb xyuas nruab nrab (xws li roj daj, cua xiav)

Xaiv los ntawm tus qauv:
Tuam Tshoj (GB) → dub (dej ntws), liab (tua hluav taws), ntsuab (dej haus)
Tebchaws Europe thiab Tebchaws Meskas (AWWA/EN) → dub (sab nraud tiv thaiv xeb), ntsuab/xiav (hauv)
Nyiv Pooj (JIS) → dub (phab ntsa sab nraud), liab (kev tua hluav taws)
