Kev tshawb nrhiav thiab cov tswv yim ntawm kev ua kom xeb tawm ntawm PPR yeeb nkab fittings

1. Taw qhia: qhov tseem ceeb ntawm PPR yeeb nkab fittings 'corrosion tsis kam

Hauv cov dej ntws niaj hnub thiab kua - Tsheb thauj cov tshuab, PPR (Random capolymer polypropylene) cov fittings tau ua ntau zuj zus. Lawv lub corrosion tsis kam yog cov cuab yeej uas tsis yog tsuas yog ua kom ntev ntev - cov haujlwm ntev ntawm cov kab ke tab sis kuj ua tau lub luag haujlwm tseem ceeb hauv kev tswj cov kua zoo. Seb nws yog cov dej ua kom muaj cov dej muaj txiaj ntsig nyob rau hauv cov chaw nyob, tshuaj lom neeg - cua txias tshuab ua lag luam tiv thaiv corrosion yog ntawm qhov tseem ceeb tshaj plaws yog qhov tseem ceeb tshaj plaws. Nkag siab txog cov cuab yeej no los ntawm kev tshawb fawb thiab tiag tiag - Cov tswv yim hauv ntiaj teb tuaj yeem muab cov kev pom zoo rau cov engineers, nruab, cov qauv tsim.

2. Kev tshawb fawb txuj ci ntawm EN 15874 PPR yeeb nkab fittings 'corrosion tsis kam

Cov khoom siv muaj pes tsawg leeg thiab cov qauv kev ntsuas qauv

Kev tshawb fawb txuj ci tau delved tob rau hauv cov khoom muaj pes tsawg leeg thiab cov qauv molecular ntawm ppr kom nkag siab txog nws corrosion - resistant cov khoom. PPR yog copolymer ua los ntawm propylene thiab ethylene monomers. Kev npaj random ntawm cov monomers hauv cov pob zeb polymer ua rau nws cov yam ntxwv tshwj xeeb. Cov pa roj carbon - Carbon Bascon nyob rau hauv tus qauv PP tau nyob tsis ruaj khov thiab tiv taus tshuaj lom neeg tawm tsam. Kev sim khomob tau pom tias muaj methyl pawg nyob rau hauv cov khoom siv propylene tseem ua rau txhim kho oxidation thiab ntau cov khoom sib xyaw. Piv txwv li, hauv kev tshawb fawb luam tawm hauv kev tshawb fawb Polymer Kev Tshawb Fawb Cov Qauv Polymopy los txheeb xyuas cov qauv molecular ntawm ppr ua ntej thiab tom qab raug rau ntau cov neeg sawv cev. Cov txiaj ntsig tau qhia tias PPR cov qauv molecular tseem tab tom tom qab ntev - lub sij hawm ua rau nws cov kua txob tsis kam ua kom tsis kam.

Ua kom nrawm corrosion ntsuas

Ua kom nrawm corrosion ntsuas yog ib txoj kev siv hauv kev tshawb fawb los ntsuas ntev - lub sijhawm ua haujlwm ntawm PPR yeeb nkab fittings. Hauv cov ntawv xeem no, PPR cov hnoos qeev yog nthuav tawm ib puag ncig corrosive, xws li kub siab tshaj plaws - av noo tej yam kev mob, rau lub sijhawm luv. Los ntawm kev coj mus kuaj rau cov mob hnyav no, cov kws tshawb nrhiav tuaj yeem twv tau cov fittings li cas ntev dua nyob hauv lub ntiaj teb kev siv. Piv txwv li, kev tshawb fawb ntawm lub tsev kawm ntawv muaj peev xwm nthuav tawm PRR cov yeeb nkab fittings kom muaj kev daws teeb meem ntawm cov tshuaj chlorine, ib qho kev ua kom haum hauv cov dej kho mob. Cov fittings tau soj ntsuam rau cov cim qhia txog kev ua tsis xws, xws li kev hloov pauv hauv cov tshuab tshuab, cov ntsej muag saum npoo av, thiab cov tshuaj lom neeg. Cov txiaj ntsig ntawm cov ntaub ntawv ua haujlwm nrawm tau muab cov ntaub ntawv muaj txiaj ntsig ntawm PPR lub peev xwm los tiv thaiv Chlorine - inducles corrosion - inductions, uas muaj feem xyuam rau cov khoom noj khoom siv dej.

3. Cov teeb meem ntawm PPR yeeb nkab fittings 'corrosion tsis kam nyob rau hauv cov ntawv thov nyob

Ntev - Term Cov Khoom Siv Dej

Hauv thaj chaw nyob hauv ib lub nroog ntug hiav txwv, PPR yeeb nkab fittings tau muab ntsia rau hauv cov khoom siv dej potable dej ntau tshaj 20 xyoo dhau los. Cov dej hauv zos muaj cov ntsev ntau ntawm cov ntsev thiab chlorine vim nws qhov sib thooj rau lub hiav txwv. Txawm hais tias tus dej hnyav, tusmp cov fittings tau qhia zoo corrosion tsis kam. Kev tshuaj xyuas ib txwm tau tshwm sim tsis muaj cov cim ntawm corrosion, xws li pitting, tawg, lossis xau dej. Cov dej ua tau zoo kuj tseem muaj kev cuam tshuam, tsis muaj cov kab mob uas tsis muaj cov kab ke los ntawm cov fittings rau hauv dej. Qhov no tiag - ntiaj teb cov ntaub ntawv qhia tau ntev - kev ntseeg tau ntawm PPR cov yeeb nkab fittings hauv kev siv dej muaj zog, kom muaj kev nyab xeeb thiab kev ua tau zoo ntawm cov dej rau cov neeg nyob hauv.

4. Cov teeb meem hauv kev lag luam hauv kev siv cov ntawv thov

Tshuaj Nroj Tsuag

Nyob rau hauv cov khoom siv tshuaj lom neeg ua lag luam uas cuam tshuam nrog kev tsim cov organic thiab inorganic tshuaj, PPR yeeb nkab fittings siv rau hauv cov kua - tsheb thauj mus los. Cov tshuaj raug thauj nrog cov acids, alkalis, thiab cov kuab tshuaj. Txawm hais tias muaj kev ua kom haum ntawm cov tshuaj no, lub PPP cov yeeb nkab fittings tau ua pov thawj yuav ruaj khov. Piv txwv li, nyob rau hauv ib tshooj ntawm cov nroj tsuag uas hydrochloric acid yuav thauj, ppr fittings tau siv rau kaum xyoo tsis muaj cim ntawm corrosion. Cov fittings tau tswj hwm lawv cov qauv txheej txheem kev ncaj ncees, kom muaj kev nyab xeeb thiab kev hloov pauv ntawm cov tshuaj. Qhov xwm txheej tseeb no hais txog qhov zoo heev corrosion tsis kam ntawm PPR yeeb nkab fittings hauv cov chaw muaj kev lag luam.

Cov chaw kaw dej kom huv

Cov chaw kaw dej kom tsawg siv cov dej nrog cov tshuaj sib xyaw ua ke, suav nrog cov hlau hnyav, orgidizing cov neeg sawv cev. PPR yeeb nkab fittings tau ua tiav tau zoo nyob rau hauv ntau cov chaw zoo li no. Hauv qhov loj - teev pov tseg kev cog tsob ntoo, PPR cov fittings tau teeb tsa hauv cov kav dej uas nqa cov dej khib nyiab rau kev tawm mus. Cov dej kho tseem muaj cov tshuaj uas muaj peev xwm ua kom haum rau ntau yam khoom. Txawm li cas los xij, PPR cov yeeb nkab fittings tau qhia tsis muaj cov cim ntawm kev xeb ntau xyoo ntawm kev ua haujlwm. Qhov xwm txheej no ua rau muaj peev xwm muaj peev xwm ntawm PPR cov yeeb nkab fittings kom tiv thaiv cov teebmeem ntawm cov dej khib nyiab ntawm cov dej khib nyiab, pab txhawb kev ua haujlwm ntawm kev kho mob.

5. Qhov ntau cuam tshuam rau PPR yeeb nkab fittings 'corrosion tsis kam

Kub thiab siab

Kev ntsuas kub siab thiab kev ntsuas kub tuaj yeem cuam tshuam rau kev tiv thaiv corrosion tsis kam ntawm PPR yeeb nkab fittings. Thaum PPR feem ntau kub - tiv taus, huab cua sov heev tuaj yeem ua rau cov khoom muag kom muag thiab ua kom muaj kev phom sij ntxiv rau kev tawm tsam tshuaj lom neeg. Ib yam li ntawd, cov kev ntsuas siab tuaj yeem tso kev ntxhov siab ntawm cov fittings, muaj peev xwm ua rau micro - cov kab nrib pleb uas tuaj yeem ua cov chaw rau kev pib corrosion. Hauv kev siv cov ntawv thov uas muaj kev kub siab thiab qib siab - kev xaiv kom zoo

Kev Siv Tshuaj

Cov concentration ntawm corrosive chemicals hauv cov kua tau thauj yog lwm qhov tseem ceeb. Kev txiav txim siab ntau dua ntawm cov acids, alkalis, lossis lwm tus neeg sawv cev corrosive tuaj yeem nrawm rau cov txheej txheem xeb. Hauv kev tshawb fawb tshawb fawb thiab cov kev siv tswv yim, nws yog qhov tseem ceeb los xav txog cov tshuaj lom neeg uas haum thaum ntsuas qhov haum ntawm PPR cov yeeb nkab fittings rau ib daim ntawv thov tshwj xeeb. Piv txwv li, hauv ib chav kuaj sim, PPR cov qauv raug nthuav tawm cov tshuaj acid
