Tshuaj lom neeg tsis kam ntawm PPR yeeb nkab fittings hauv kev lag luam tshuaj lom neeg

1. Taw qhia rau PPR Yeeb Nkab Fittings

Nyob rau hauv cov kev sib txuas lus zoo thiab xav tau kev lag luam ntawm kev lag luam tshuaj, kev xaiv ntawm cov ntaub ntawv rau cov tshuab luam rau cov tshuab raj yog ntawm qhov tseem ceeb tshaj plaws. Polypropylene Random Copolymer (PPR) cov yeeb nkab fittings tau tawm raws li kev ntseeg siab thiab siab - ua cov tshuaj vim lawv cov tshuaj tshwj xeeb. PPR yog ib thermoplicity polymer uas ua ke cov khoom ntawm polypropylene nrog ethylene monomer units, uas muab nws txhim kho cov neeg kho tshuab thiab tshuaj lom neeg. Cov fittings cov yeeb nkab tau siv los txuas, kev tswj, hloov cov kev taw qhia, thiab hloov cov tshuaj lom neeg hauv pipelines. Lawv lub peev xwm tiv thaiv ntau yam tshuaj lom neeg ua rau lawv muaj feem xyuam rau ntau yam tshuaj lom neeg, los ntawm kev tsim khoom rau kev khaws cia thiab tsheb thauj mus los.

2. Molecular qauv thiab tshuaj lom neeg tiv thaiv mechanism

Cov tshuaj tua hluav taws xob tiv thaiv ntawm PPR cov yeeb nkab fittings tuaj yeem ua rau lawv cov qauv molecular. Cov saw ntev ntawm polypropylene nraub qaum, nrog rau cov khoom xa tawm cov ethylene coj, tsim cov qauv ruaj khov thiab tsis yog - polar qauv. Tsis yog - cov ntaub ntawv hauv qab daus feem ntau tsawg dua ua kom haum nrog cov tshuaj ncov qaumteb qab zib, uas muaj ntau hauv kev lag luam tshuaj. Qhov no tsis yog - polarity tiv thaiv ntau yam tshuaj los ntawm txawv rau lub polymer matrix, txo qhov kev pheej hmoo ntawm kev txwv tsis pub tshuaj lom neeg. Ib qho ntxiv, qhov tsis muaj kev cuam tshuam cov pab pawg ua haujlwm hauv lub pob molecular qauv ntxiv txhim kho nws txoj kev tiv thaiv kom muaj tshuaj lom neeg tawm tsam. Piv txwv li, muaj zog acids thiab cov hauv paus uas tuaj yeem corrode medsals thiab txwv tsis pub lwm cov ntaub ntawv yas muaj me ntsis cuam tshuam rau PPR yeeb nkab. Cov qauv molecular ruaj khov uas cov yeeb nkab fittings tswj lawv cov qauv kev ntseeg siab thiab kev ua haujlwm txawm tias raug rau ib puag ncig hnyav dua ncua sij hawm.

3. Kev ua tau zoo hauv cov chaw sib txawv

PPR yeeb nkab fittings ua rau pom kev ua tau zoo tshaj plaws thoob plaws ntau hom tshuaj ib puag ncig. Hauv cov acidic ib puag ncig, xws li cov uas muaj sulfuric acid los yog ppr qhia tau zoo tsis kam. Cov kua qaub no, uas nquag siv rau hauv cov tshuaj lom neeg thiab kev ua tiav, tuaj yeem ua rau muaj mob hauv cov kav hlau hlau. Txawm li cas los xij, PPR yeeb nkab fittings nyob tsis muaj kev cuam tshuam, tiv thaiv kev xau thiab ua kom muaj kev thauj mus los ntawm acidic tshuaj. Hauv kev kawm alkaline alkaline, PPR kuj ua tau zoo. Sodium hydrocholes thiab potassium hydroxide, uas yog siv nyob rau ntau cov txheej txheem tshuaj lom neeg thiab kev kho dej khib nyiab, tsis txhob thuam PPR cov ntaub ntawv. Qhov no ua rau kev xaiv piping zoo tshaj plaws rau cov khoom siv hauv cov chaw uas ua ob qho tib si acidic thiab alkaline chemical.

Tsis tas li ntawd, PPR yeeb nkab fittings tiv taus ntau cov kuab tshuaj organic, xws li dej cawv, esters, thiab cov khoom siv tshuaj tua kab. Cov kuab tshuaj no tau siv dav hauv kev lag luam tshuaj lom neeg rau kev ntxuav, rho tawm, thiab ua cov tshuaj tiv thaiv. Lub peev xwm ntawm PPR tiv thaiv cov kuab tshuaj no yam tsis muaj o, lossis poob nws cov khoom siv dag zog yog qhov tseem ceeb rau kev tswj cov txheej txheem ua haujlwm thiab kev nyab xeeb ntawm cov txheej txheem tshuaj lom neeg.

4. Kev sib piv nrog lwm cov ntaub ntawv

Thaum piv rau cov ntaub ntawv ib txwm muaj xws li hlau thiab lwm cov yas, PPR yeeb nkab fittings kom zoo nyob rau hauv cov nqe lus ntawm cov tshuaj tiv thaiv. Cov hlau, xws li hlau thiab tooj, muaj feem ntau yog mob corrosion thaum raug tshuaj lom neeg, tshwj xeeb yog nyob ntawm kev ya raws. Corrosion tsis tsuas yog tsis muaj zog cov txheej txheem kev ntseeg ntawm cov kav hlau tab sis kuj tsis huv cov tshuaj thauj khoom, uas tuaj yeem yog qhov teeb meem loj hauv kev lag luam tshuaj. Hauv kev sib piv, PPR yeeb nkab fittings tsis yog - corrosive thiab tsis paug cov tshuaj uas lawv nqa.

Lwm cov plastics, xws li PVC (polyvinyl chloride), kuj tseem siv tau hauv kev lag luam tshuaj lom zem tab sis muaj kev txwv hauv kev tiv thaiv tshuaj lom neeg. PVC tsis tshua tiv taus qee cov kuab tshuaj thiab cov tshuaj kub piv rau PPR. PPR yeeb nkab tuaj yeem ua haujlwm nyob rau hauv dav dav ntau, los ntawm}}} degree rau ntau yam kev siv tshuaj lom neeg uas kub. Qhov kub siab no tiv thaiv, ua ke nrog cov tshuaj lom neeg zoo dua, ua rau kev xaiv tshuaj lom neeg ntau ntxiv.

5. Tus nqi - Cov txiaj ntsig thiab ntev - cov txiaj ntsig

Ntxiv rau lawv cov tshuaj lom neeg zoo heev, ppr yeeb nkab fittings pab them nqi - ua tau zoo thiab ntev tau txais txiaj ntsig hauv kev lag luam tshuaj. Lub installation ntawm PPR yeeb nkab fittings yog qhov yooj yim thiab yuav tsum muaj tsawg zog piv rau cov kav hlau. Lawv lub teeb yuag txo cov nqi tsheb thauj mus los thiab ua kom yooj yim kov thaum lub teeb nruab. Ntxiv mus, vim lawv cov tshuaj lom neeg ntau heev, ppr cov yeeb nkab fittings muaj lub neej kev pab ntau dua. Lawv yuav tsum tau hloov ntau zaus los hloov cov ntaub ntawv uas muaj kev phom sij rau cov tshuaj lom neeg, uas txo cov nqi txij nkawm nyob rau lub sijhawm. Qhov kev pheej hmoo ntawm cov dej xau thiab kev paug kuj txo cov peev xwm txo qis thiab ib puag ncig kev nqis peev rau cov suab paj nyiaj txiag.

Hauv kev xaus, PPR yeeb nkab fittings ua ib lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj lom neeg vim lawv cov tshuaj lom zem heev. Lawv cov qauv molecular, kev ua tau zoo hauv ntau yam chaw tshuaj xyuas ib puag ncig, zoo dua lwm cov ntaub ntawv, thiab tus nqi - ua tau zoo tshaj plaws ua rau lawv muaj tshuaj lom neeg cov tshuab tshuaj. Raws li kev lag luam tshuaj ntxiv mus hloov zuj zus thiab siv cov khoom siv tsis zoo xws li PPR yeeb nkab fittings tsuas yog xav kom nce ntxiv.
