Taw qhia rau PEX Yeeb Nkab:
PEX cev, luv luv rau cross-linked polyethylene yeeb nkab, yog cov khoom siv ntau yam thiab cov kav dej tshiab uas tau txais kev nyiam nyob rau xyoo tas los no. Nws yog lub npe hu rau nws yooj, durability, thiab yooj yim ntawm installation. PEX yeeb nkab yog lwm txoj hauv kev zoo rau cov khoom siv kav dej xws li tooj liab thiab PVC, muab ntau yam zoo hauv ntau daim ntawv thov. Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog cov txheej txheem ntawm PEX yeeb nkab thiab nws cov txiaj ntsig, ua rau nws yog qhov kev xaiv zoo rau cov kav dej niaj hnub.
Technical nta thiab qhov zoo ntawm PEX Yeeb Nkab:
1.Cov txheej txheem sib txuas
Kev sib txuas ntawm polyethylene molecules yog qhov tseem ceeb uas ua rau PEX yeeb nkab sib nrug los ntawm lwm cov khoom siv kav dej. Hla-txuas txuas txhim kho cov yeeb nkab kev ua tau zoo thiab muab nws cov khoom zoo dua. Muaj peb txoj hauv kev ntawm kev sib txuas: PEX-a, PEX-b, thiab PEX-c txheej txheem.
PEX-a: Txoj kev no suav nrog qhov siab tshaj plaws ntawm kev sib txuas sib txuas, uas ua rau cov yeeb nkab nrog kev ua tau zoo thiab kev nco zoo. PEX-ib cov kav dej tuaj yeem nthuav dav thiab tom qab ntawd cog lus rov qab mus rau lawv cov qauv qub, ua rau lawv zoo tagnrho rau kev nkhaus lossis kev sib txuas.
PEX-b: Cov txheej txheem no muab kev sib txuas nruab nrab thiab tsim cov yeeb nkab uas yog me ntsis nruj dua PEX-a. PEX-b cov kav dej yog pheej yig dua thiab tsim nyog rau kev siv cov kav dej dav dav.
PEX-c: Txoj kev no suav nrog cov kab hluav taws xob hluav taws xob lossis gamma-ray irradiation los hla-txuas cov molecules. PEX-c cov kav dej muaj qhov kub thiab txias tsis kam, tiam sis tsis yooj yim dua piv rau PEX-a thiab PEX-b kav.
2. Flexibility thiab Khoov Radius
Ib qho ntawm qhov zoo tshaj plaws ntawm PEX yeeb nkab yog nws qhov yooj yim heev. Nws tuaj yeem khoov tau yooj yim thiab nkhaus nyob ib puag ncig cov teeb meem, txo qhov kev xav tau ntxiv rau fittings thiab txo qhov kev pheej hmoo ntawm kev xau. Lub vojvoog khoov, lossis qhov tsawg kawg nkaus lub vojvoog uas cov yeeb nkab tuaj yeem khoov tau yam tsis muaj kev puas tsuaj, yog qhov tseem ceeb rau kev txiav txim siab. PEX yeeb nkab feem ntau muaj lub vojvoog me me dua li cov khoom siv ib txwm siv, tso cai rau kev txhim kho ntau yam.
3. Durability thiab Corrosion Resistance
PEX yeeb nkab yog qhov ruaj khov thiab tiv taus corrosion, ua rau nws muaj kev ntseeg siab rau cov kav dej ntev ntev. Tsis zoo li cov kav dej tooj liab, PEX tsis corrode lossis txhim kho cov nyiaj tso nyiaj hauv lub sijhawm. Nws kuj tseem tiv taus cov tshuaj lom neeg feem ntau pom hauv av thiab dej, ua kom nws txoj sia nyob ntev hauv ntau qhov chaw.
4. Thermal Expansion and Freeze Resistance
Lwm qhov zoo tshaj plaws ntawm PEX yeeb nkab yog nws lub peev xwm nthuav dav thiab cog lus nrog kev hloov pauv kub. Cov yam ntxwv no txo cov kev ntxhov siab ntawm cov kav dej, txo qhov kev pheej hmoo ntawm cov yeeb nkab tawg lossis xau vim thermal expansion. PEX yeeb nkab kuj tseem khov-tiv taus, txhais tau tias nws tuaj yeem nthuav dav yam tsis muaj kev tawg thaum dej hauv cov yeeb nkab khov. Qhov kev ua tau zoo no tau txais txiaj ntsig tshwj xeeb hauv cov huab cua txias lossis cov ntawv thov uas cov kav dej raug rau qhov kub thiab txias.
5. Resistance rau Scaling thiab Buildup
PEX yeeb nkab muaj qhov zoo nkauj sab hauv uas tiv thaiv qhov ntsuas thiab txhim kho, ua kom pom cov dej ntws zoo dhau sijhawm. Tsis zoo li cov kav dej tooj liab, uas tuaj yeem tsim cov pob zeb hauv av, PEX tseem huv thiab tswj nws qhov kev ua tau zoo. Qhov kev tiv thaiv kev ntsuas no ua rau kev txhim kho lub zog ua haujlwm thiab txo cov kev xav tau ntawm kev saib xyuas.
Daim ntawv thov thiab cov lus xaus:
1.Residential Plumbing Systems
PEX yeeb nkab tau dhau los ua qhov kev xaiv nrov rau cov kav dej hauv tsev vim nws qhov yooj yim ntawm kev teeb tsa, hloov tau yooj yim, thiab ua haujlwm ntev. Nws yog feem ntau siv rau cov kav dej kub thiab dej txias, cov cua kub hauv pem teb, thiab txawm rau repiping tej yaam num hauv cov tsev laus.
2. Cov ntawv thov kev lag luam thiab kev lag luam
Ntxiv nrog rau kev siv hauv tsev, PEX yeeb nkab pom nws cov ntawv thov hauv kev lag luam thiab kev lag luam. Nws yog qhov tsim nyog rau cov kav dej hauv tsev kawm ntawv, tsev kho mob, tsev so, thiab lwm qhov chaw xav tau siab.PEX cev's yooj thiab yooj yim ntawm installation ua rau nws muaj txiaj ntsig zoo rau cov kav dej sib txuas.
