Cov kav dej kais dej puas huv?
Cov kav dej yog ib feem tseem ceeb ntawm cov phiaj xwm zais. Yog tias cov kav dej xau los yog tawg, lawv feem ntau yuav ua rau muaj kev cuam tshuam tsis zoo. Yog li ntawd, kev nkag siab txog cov khoom siv yeeb nkab thiab cov yam ntxwv ntawm cov kav dej ua ntej tuaj yeem ua kom tsis txhob muaj teeb meem tsis tsim nyog.
Yuav xaiv cov kav dej li cas?
Feem ntau siv cov kav dej rau kev kho kom zoo nkauj feem ntau muab faib ua plaub pawg: galvanized kav, aluminium-yas kav, PPR kav, thiab tooj liab / hlau kav.
Galvanized kav
Rau cov kav dej galvanized uas tsis tau siv rau lub sijhawm ntev, nws yuav pom tias cov dej "daj" ntws tawm, tshwj xeeb tshaj yog nyob rau hauv cov kav hlau galvanized hauv cov tsev qub, uas yog qhov yooj yim heev los tshwm sim thiab tsim kev puas tsuaj rau tib neeg kev noj qab haus huv.
Tam sim no ntau lub tebchaws tau txwv tsis pub cov kav dej galvanized, tab sis qee cov zej zog qub, tshwj xeeb tshaj yog cov uas tsis tau kho dua tshiab rau ntau tshaj 30 xyoo, tseem siv cov kav dej galvanized ua cov kav dej.
Tom qab cov yeeb nkab galvanized tau siv rau lub sijhawm, muaj ntau cov xeb hauv cov yeeb nkab. Cov dej daj uas ntws tawm tsis yog tsuas yog ua rau cov khoom tsis huv, tab sis kuj yog sib xyaw nrog cov kab mob uas loj hlob ntawm cov phab ntsa ntxhib. Cov xeb ua rau cov ntsiab lus hlau hnyav hauv dej siab dhau, uas ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.
Aluminium-yas yeeb nkab
Aluminium-yas yeeb nkab yog ib qho khoom siv yeeb nkab nrov ntawm kev ua lag luam. Vim nws lub teeb yuag, durability, yooj yim siv, thiab khoov, nws maj mam hloov galvanized kav hauv xyoo 1960 thiab 1970s. Ntau lub nroog hauv nroog siv cov kav dej txhuas-yas.
Txawm li cas los xij, vim lub sij hawm ntev thermal expansion thiab contraction, phab ntsa ntawm aluminium-yas yeeb nkab yuav raug misaligned, ua rau to. Hauv cov nroog loj nrog cov ntsiab lus kho kom zoo nkauj tshiab, cov kav dej txhuas-yas tau maj mam poob lawv lub khw. Kuv ntseeg tias yav tom ntej, cov kav dej txhuas-yas kuj tseem yuav raug tshem tawm.
Raws li cov kav dej xa dej, cov kav dej txhuas-yas yeeb nkab muaj lub zog txaus, tab sis thaum lub zog sab nraud loj dhau, nws yuav cuam tshuam rau lub zog ntawm cov yeeb nkab, yog li nws tsim nyog rau cov kav dej qhib lossis faus rau hauv phab ntsa, tsis sib sib zog nqus hauv av.
Nyob rau tib lub sijhawm, vim tias cov yeeb nkab aluminium-yas tau txais kev sib txuas ntawm ferrule, nws yog ib qho tsim nyog yuav tsum tau ua qhov kev ntsuam xyuas siab kom ntseeg tau tias qhov kev sib txuas ruaj khov thiab khaws cov ntim ntim txaus kom tsis txhob rub tawm.
Copper yeeb nkab / stainless hlau yeeb nkab
High-end hlau kav xws li cov kav dej tooj liab / stainless hlau kav yog cov khoom zoo tshaj plaws hauv cov kav dej. Lawv tau lees paub tias yog ib qho zoo tshaj plaws, tshiab, txuag hluav taws xob thiab ib puag ncig cov kav dej, thiab tau dhau los ua cov qauv tam sim no thiab kev txhim kho.
Vuam feem ntau siv rau kev teeb tsa, yog li nws muaj lub zog siab thiab kev ua haujlwm ruaj khov. Nws feem ntau yog siv rau hauv cov kav dej kais dej, cua sov thiab cov kav dej txias.
Vim nws cov nqi siab thiab cov txheej txheem kev tsim kho, nws feem ntau yog siv ntau dua hauv cov tsev siab lossis tsev villas.
PPR cev
Raws li hom tshiab ntawm cov khoom siv yeeb nkab, PPR yeeb nkab muaj qhov tshwj xeeb zoo. Nws tuaj yeem siv ua ob qho tib si cov kav dej txias thiab cov kav dej kub. Vim nws tsis muaj tshuaj lom, lub teeb yuag, siab tsis kam thiab corrosion kuj, nws yog cov khoom siv dej zoo tshaj plaws rau kev kho kom zoo nkauj tam sim no.
PPR yeeb nkab tsis yog tsuas yog haum rau cov kav dej txias, tab sis kuj rau cov kav dej kub, thiab txawm tias cov kav dej ntshiab huv.
Lub interface ntawm PPR yeeb nkab txais cov tshuab kub yaj, thiab cov kav dej tau ua tiav ua ke. Yog li ntawd, ib zaug kev ntsuam xyuas siab dhau lawm, yuav tsis muaj kev laus thiab cov dej ntws mus ntev li cov kav dej txhuas-yas, thiab cov kav dej PPR yuav tsis ntsuas.
PPR cov kav dej yog tus nqi nruab nrab thiab muaj kev ua haujlwm ruaj khov. Nyob rau hauv cov xwm txheej zoo tagnrho, lub neej kev pabcuam yog mus txog 50 xyoo, tab sis nws qhov kub thiab txias tsis kam yog me ntsis zuj zus, thiab lub sijhawm ua haujlwm kub yuav tsum qis dua 70 degree.
Txhua tus tuaj yeem xaiv cov kav dej hauv lawv lub tsev, tab sis peb tsis tuaj yeem yooj yim hloov cov kav dej hauv cov dej hauv pej xeem thiab thaum lawv tau teeb tsa. Cov dej los ntawm cov nroj tsuag dej yog haus. Tom qab dhau los ntawm cov kav dej hauv cov kav dej tau hloov kho lub sijhawm sib txawv, koj puas tuaj yeem haus cov kais dej ncaj qha?
Nws raug nquahu kom koj nruab adej purifierhauv chav ua noj kom ntxuav cov kais dej rau lub sijhawm kawg ua ntej cov dej nkag hauv peb lub qhov ncauj, kom peb haus tau nrog kev ntseeg siab.
