Qhov teeb meem ntawm Brown Spots
Qhov tshwm sim ntawm cov xim av ntawm cov dej saum npoo av-txawm yog nyob rau hauv lub pas dej da dej, lub pas dej zoo nkauj, lossis dej nta- yog qhov teeb meem tshwm sim thiab ntxhov siab. Cov teeb meem tsis zoo no feem ntau qhia tau hais tias muaj tshuaj lom neeg tsis sib haum, tshwj xeeb tshaj yog pH tsis sib haum nrog rau cov hlau yaj xws li hlau, tooj liab, lossis manganese. Yog tias tsis kho, cov stains no tuaj yeem ua mus tas li, ua rau kev zoo nkauj thiab ua rau muaj kev ncaj ncees ntawm cov dej. Phau ntawv qhia no muab cov txheej txheem, cov kauj ruam -los ntawm- cov txheej txheem kev kawm rau kev txheeb xyuas, kho, thiab tiv thaiv cov xim av, tsom rau kev hloov pH, pom, flocculation, thiab lub luag haujlwm ntawm ntau yam tshuaj kho dej.
Vim li cas Brown Spots Form?
Txhawm rau tiv thaiv cov xim av kom zoo, ib tus yuav tsum xub nkag siab txog chemistry ntawm kev ua si. Qhov teeb meem feem ntau tshwm sim los ntawm kev sib xyaw ntawm ob yam:
Qhov pH Factor
pH yog ib qho kev ntsuas ntawm cov kua qaub lossis cov dej hauv nruab nrab, ntawm qhov ntsuas ntawm 0 txog 14. Thaum pH poob qis heev (acidic), dej yuav "khaus" lossis corrosive. Cov dej txhoj puab heev no tuaj yeem tso cov hlau ncaj qha los ntawm lub cev cov khoom sib xyaws -xws li cov kav dej tooj liab, cov khoom siv hluav taws xob, cov khoom siv tooj dag, lossis txawm tias cov ntaiv xeb- thiab tuav lawv hauv lub xeev yaj.
Hlau Factor
Cov hlau xws li hlau, tooj liab, thiab manganese nkag mus rau hauv dej los ntawm ntau qhov chaw:
- Qhov Chaw Dej:Cov dej zoo yog qhov ua txhaum ntau, feem ntau muaj cov ntsiab lus siab ntawm cov zaub mov no.
- Cov khoom siv Corroding:Raws li tau hais, pH qis tuaj yeem ua rau cov dej yaj cov hlau los ntawm cov khoom siv hauv pas dej.
- Tshuaj Additives:Qee cov algaecides yog tooj liab-raws li, thiab siv ntau dhau tuaj yeem ua rau muaj tooj liab hauv dej.
- Geology:Lub ntuj geology los ntawm qhov chaw dej dhau los cuam tshuam nws cov ntsiab lus ntxhia. Cov cheeb tsam uas muaj cov ntsiab lus hlau siab hauv cov av feem ntau yuav tsim cov dej nrog cov teeb meem staining.
Thaum cov pH raug kho los yog cov dej poob siab nrog cov tshuaj chlorine (ib qho muaj zog oxidizer), cov hlau yaj no tuaj yeem tso tawm ntawm cov tshuaj. Qhov no txhais tau hais tias lawv hloov los ntawm cov yaj, tsis pom lub xeev mus rau ib qho khoom, pom ib qho, tso rau hauv lub pas dej ua ke thiab tsim cov yam ntxwv me ntsis.
| Hlau | Tej yam tshwm sim | Common Source |
|---|---|---|
| Hlau | Reddish-xim av, tsaus xim av, los yog yellowish-xim av "xeb" | Lub pas dej zoo nkauj, rusty ladders, corroding rebar |
| Tooj | Xiav-ntsuab ntsuab, teal, dub, lossis liab doog blotches | Copper-raws li algaecides, corroding heat exchangers / kav dej |
| Manganese | Pinkish-liab, xim av tsaus, lossis xim dub | Qhov chaw dej, tshwj xeeb geological tej yam kev mob |
Ib txoj hauv kev yooj yim los txheeb xyuas qhov stain yog qhov ntsuas vitamin C. Txiav ib ntsiav tshuaj vitamin C thiab rub nws ncaj qha rau ntawm qhov chaw me me. Yog hais tias lub stain lightens los yog ploj mus, nws yog ib qho zoo li hlau -raws li stain. Qhov no yog vim ascorbic acid ua raws li kev txo tus neeg sawv cev thiab chelator, rub cov hlau tawm ntawm qhov chaw.
Txoj Kev Npaj Ua Tam Sim No: Ib Kauj Ruam -los ntawm - Cov Txheej Txheem Txheej Txheem
Lorem ipsum dolor sit amet consectetur adipisicing elit.
Kauj Ruam 1: Ua ntej-Kev Kho & Kev Ntsuas Dej
Ua ntej yuav ntxiv cov tshuaj, koj yuav tsum nkag siab koj qhov pib.
- Test dej:Siv cov khoom siv ntsuas kev ntseeg siab los ntsuas pH, alkalinity, thiab chlorine qib. Ib kauj ruam tseem ceeb rau cov hlau stains yog txo qis cov tshuaj chlorine dawb kom qis dua 1 ppm (los yog ze li 0 ppm li sai tau). Cov tshuaj chlorine tuaj yeem ua rau muaj ntau yam stains - tshem tawm cov tshuaj xws li ascorbic acid.
- Paub meej hom Stain:Ua qhov ntsuas vitamin C kom paub meej tias muaj hlau. Rau cov stains tooj liab, kev ntsuas dej tshwj xeeb rau tooj liab yog qhov tseeb dua.
Kauj Ruam 2: Kho thiab Tswj pH
Vim li cas pH tseem ceeb
Chlorine's active germicidal daim ntawv,hypochlorous acid (HOCl), yog ntau tshaj ntawm pH 5.5-6.0, tab sis qhov no yog corrosive. Cov tswv yim"qab zib" yog pH 7.2-7.6- Muaj kev nyab xeeb rau cov neeg siv khoom / khoom siv thaum tuav cov tshuaj chlorine txaus. Tshaj pH 7.6, chlorine kev ua haujlwm poob qis heev.
Yuav kho li cas
- pH siab dhau lawm→ Ntxivsodium bisulfate (NaHSO₄)los yogmuriatic acid (HCl).
- pH tsawg dhau→ Ntxivsodium carbonate (soda tshauv, Na₂CO₃)los yogsodium hydroxide (Lye, NaOH).
Txoj Cai Tseem Ceeb
Ib txwmkho pH ua ntej shocking/super-chlorinating. Tsis txhob sib tov pH adjusters nrog chlorine concentrate - ntxiv rau lawv cais kom tsis txhob muaj kev phom sij txaus ntshai lossis tso pa tawm.
Kauj Ruam 3: Lim thiab Flocculation
Tom qab pH sib npaug, mus rau lub cev tshem tawm cov hlau precipitated.
- Khiav lub lim dej tsis tu ncua- Kev xa khoom faib tshuaj thiab ntes cov khoom tshem tawm.
- Ntxiv ib flocculant- cov polymer no-raws li cov neeg ua hauj lwm khi cov khoom zoo rau hauv pawg loj (flocs) uas yog nyob rau hauv lub tshuab nqus tsev los yog lim tau.
- Cov ntsiab lus tseem ceeb rau kev ua tau zoo:
- Khaws pH nyob rau hauv cov khoom zoo tshaj plaws (feem ntaupH 7-8).
- Circulate nrog twj tso kua mis khiav rau ib lub sij hawm kom disperse thiab qhib flocculation.
- Tig lub twj tso kua mis tom qab tso cai rau flocs kom daws tau tag nrho.
Kauj Ruam 4: Tshaj tawm -Kev kho mob thiab rov ua kom rov zoo
Tom qab cov stains raug tshem tawm thiab cov khoom sib hais / lim:
- Nqus kom pov tseg- manually tshem tawm cov khib nyiab hauv pem teb, tso dej tawmtawmntawm qhov system (tsis yog los ntawm lub lim) kom tshem tawm cov khoom siv hlau.
- Ntxuav lub lim- rov qab los yog ntxuav kom huv si kom tshem tawm cov flocculant thiab hlau residues.
- Rebalance chemistry– maj mam rov qab chlorine rau1-3 ppm, tom qab ntawd kho pH, alkalinity, thiab calcium hardness rau qib zoo tagnrho.
- Ntxiv tus neeg sawv cev sequestering- qhov no khi hlau ions hauv kev daws teeb meem, tiv thaiv nag lossis daus yav tom ntej thiab khaws cia.
Tshuaj muaj nuj nqi hauv kev kho dej
Kev nkag siab txog kev ua haujlwm ntawm txhua yam tshuaj siv yog qhov tseem ceeb rau kev tswj dej kom zoo. Cov ntawv hais txog ob peb, thiab ob peb yam ntxiv tau piav qhia hauv qab no raws li cov lus qhia.
| Tshuaj | Lub luag haujlwm tseem ceeb | Nws ua haujlwm li cas |
|---|---|---|
| Chlorine | Tshuaj tua kab mob | Lub zog oxidizer siv los tua cov kab mob, algae, thiab lwm yam kab mob. Nws txoj kev ua tau zoo yog nyob ntawm pH. |
| PH Adjuster (Acid / Base) | pH tswj | Txo (acid) lossis nce (pH) ntawm cov dej los tsim kom muaj kev ruaj khov, tsis yog -ib puag ncig corrosive uas ua kom cov tshuaj chlorine ua tau zoo. |
| Algaecide | Tiv thaiv / tua Algae | Cov tshuaj tshwj xeeb uas inhibits algae kev loj hlob. Kev siv tooj liab ntau dhau -raws li algaecides tuaj yeem yog qhov tseem ceeb ntawm cov xim tooj liab. |
| Flocculant / Clarifier | Kev qhia meej | Coagulates cov khoom me me uas raug tshem tawm mus rau hauv qhov loj dua, lim tau clumps (flocs), txhim kho cov dej ntshiab. Piv txwv suav nrog polyacrylamides thiab aluminium-raws li cov khoom . |
| Anti-Limescale | Kev Tiv Thaiv Scale | Tiv thaiv cov nag lossis daus thiab tsim cov calcium carbonate (scale) ntawm qhov chaw thiab hauv cov khoom siv. |
| Stabilizer (Cyanuric Acid) | Chlorine Stabilizer | Tiv thaiv chlorine los ntawm kev puas tsuaj sai los ntawm lub hnub ultraviolet (UV) rays, ua kom nws cov txiaj ntsig zoo hauv cov pas dej sab nraum zoov. |
Nco tseg ntawm Ntau- Cov Khoom Siv Ua Haujlwm:Kev ua lag luam muaj ntau yam "tag nrho-hauv-ib" lossis "10-action" cov khoom uas sib xyaw ua ke ntau yam ntawm cov haujlwm no. Thaum yooj yim, nws yog ib qho tseem ceeb kom nkag siab txog tus kheej cov khoom xyaw. Piv txwv li, ib yam khoom uas yog ob qho tib si clarifier thiab algaecide tej zaum yuav yog ib qho kev tiv thaiv zoo, tab sis rau ib qho teeb meem xws li hnyav hlau staining, cov phiaj xwm kev kho mob feem ntau zoo dua.
Kev Tiv Thaiv: Ntev -Lub Sij Hawm Lub Sij Hawm
Txoj hauv kev zoo tshaj plaws los daws cov xim av yog tiv thaiv lawv los ntawm kev tsim thawj qhov chaw.
- Ua kom muaj dej sib xyaw ua ke:Tsis tu ncua sim thiab kho cov dej tsawg kawg 2-3 zaug hauv ib lub lis piam. Khaws pH, alkalinity, thiab chlorine nyob rau hauv lawv qhov chaw kom zoo yog ib qho kev tiv thaiv zoo tshaj plaws.
- Qhov Chaw Tswj Dej:Yog tias koj siv dej zoo, xav txog kev txhim kho tag nrho - lub tsev pom los yog siv lub tshuab ua ntej - lim thaum sau lub pas dej kom tshem tawm cov hlau ua ntej lawv nkag mus rau hauv lub cev.
- Saib xyuas kev siv Algaecide:Tsis txhob siv tooj liab ntau dhau -raws li algaecides. Xav txog cov uas tsis yog- tooj liab hloov rau kev tu txhua hnub.
- Tshawb xyuas cov cuab yeej:Tsis tu ncua xyuas cov ntaiv, cov twj tso kua mis, thiab cov cua sov kom pom cov cim ntawm xeb lossis xeb. Hloov cov khoom hlau puas tam sim ntawd.
- Siv Tus Neeg Saib Xyuas Sequestering:Raws li kev ntsuas kev tiv thaiv, ntxiv cov hlau sequestering tus neeg sawv cev tsis tu ncua kom "kaw" cov kab hlau hauv dej ua ntej lawv tuaj yeem ua rau saum npoo.
Los ntawm kev ua raws li cov lus qhia dav dav no, ib tus tuaj yeem kuaj xyuas, kho, thiab tiv thaiv qhov teeb meem ntawm cov xim av ntawm qhov chaw dej, ua kom muaj kev huv, nyab xeeb, thiab zoo nkauj hauv dej.
