Kev ntxuav cov kua qaub, tseem hu ua kua qaub ua kua, npaj cov pob zeb ua kom pom lub foob. Koj kuj tseem tuaj yeem siv cov kua qaub hauv cov ntsiab lus tsis muaj zog kom tshem cov pob zeb hauv av dawb (efflorescence) thiab hnyav hnyav. Kev ntxuav cov kua qaub yog qhov txaus ntshai rau tib neeg, nroj tsuag, thiab cov khoom siv hlau, tshwj xeeb tshaj yog nyob hauv tsev qhov twg cov pa tuaj yeem mloog zoo.
Tsis txhob cuam tshuam cov txheej txheem no nrog cov kua qaub, uas ua xim rau cov pob zeb. Tsis pom zoo kom ntxuav cov kua qaub ua ntej thov pleev xim.
Cov kauj ruam
Ntu 1 ntawm 3: Teeb
Kauj Ruam 1. Tshem cov av thiab roj
Txhuam lossis nqus cov av los ntawm cov qhob. Yog tias muaj cov roj av, tshem tawm lawv nrog cov tshuaj degreaser lossis xab npum alkali. Yaug kom huv nrog dej.
- Yog tias cov dej hlaws saum npoo av, cov kua qaub yuav ua haujlwm tsis raug. Degreasing yuav tsum daws qhov teeb meem no.
- Trisodium phosphate (TSP) cov tshuaj ntxuav tes tsis pom zoo. Ib qho uas seem tshuav nyob tom qab tuaj yeem tawm tsam nrog cov kua qaub kom tso roj txaus ntshai.
Kauj Ruam 2. Xaiv koj cov kua qaub
Xaiv cov khoom tu lossis kos duab raws li koj qib kev paub thiab qhov chaw nyob:
- Sulfamic acid yog qhov nyab xeeb tshaj plaws los daws, thiab pom zoo rau cov tsis yog kws tshaj lij.
- Phosphoric acid tsim cov pa taws tsawg. Siv nws hauv cov chav uas muaj cov hlau tsis xeb lossis lwm yam hlau tsis muaj zog. Nws kuj yog qhov kev xaiv zoo yog tias koj tsuas yog ntxuav tawm cov ntxhia pob zeb.
- Muriatic acid (hydrochloric acid) yog qhov kev phom sij tshaj plaws thiab ua rau muaj pa taws ntau. Pom zoo rau cov kws tshaj lij ua haujlwm sab nraum zoov.
Kauj Ruam 3. Ua raws li cov lus qhia kev nyab xeeb
Cov kua qaub no yog qee yam tshuaj txaus ntshai tshaj plaws muaj rau siv hauv tsev. Hnav cov hnab looj tes tiv taus cov kua qaub, khau roj hmab, thiab cov iav pov thawj pov thawj. Tiv thaiv koj lub ntsws nrog lub tshuab ua pa nrog lub lim dej lim dej, thiab siv cov kiv cua txhawm rau txhim kho qhov cua yog tias tsim nyog. Tiv thaiv cov tawv nqaij nrog cov khaub ncaws zoo haum tsawg kawg, thiab hom phiaj nrog daim npog ntsej muag ntxiv rau PVC lossis Butyl npog npog lossis ntaub pua chaw.
- Khaws dej nyob ze kom ntxuav qhov nchuav tawm ntawm daim tawv nqaij lossis khaub ncaws. Da dej thiab qhov chaw ntxuav qhov muag yog qhov zoo tshaj.
- Khaws cov dej qab zib lossis txiv qaub hauv vaj nyob ze kom tshem tawm qhov nchuav rau hauv av.
Kauj Ruam 4. Ntxiv cov kua qaub rau hauv dej hauv lub thoob yas lossis dej tso dej
Tsis zoo li cov hlau, txhua yam yas uas tuaj yeem tiv taus acid puas tsuaj ntawm cov tshuaj no. Txhawm rau zam kev ua phem, nchuav dej rau hauv lub thoob ua ntej, tom qab ntawd ntxiv cov kua qaub maj mam. Ncua mus rau cov chaw tsim khoom cov lus qhia ntawm cov thawv kua qaub dhau cov lus qhia hauv qab no. Cov piv piv dav no haum rau qee qhov sib xyaw tab sis tsis yog txhua yam:
- Sulfamic acid: 1 phaus hmoov lossis muaju rau 1 nkas loos dej kub (120 grams rau 1 L dej).
- Phosphoric acid: dilute rau 20-40%.
- Muriatic acid: sib tov 3 mus rau 4 ntu dej nrog 1 feem kua qaub, lossis ua raws daim ntawv qhia qhia rau 10% kev mloog zoo (15% rau tawv, ua vaj tsev du).
- Cov kev daws teeb meem no yog txhawm rau kos lub pob zeb. Yog tias koj tsuas yog tshem tawm cov ntxhia hauv av (ua kom tawg), siv qhov sib xyaw ua kom tsis muaj zog ntau (10: 1 lossis 16: 1 rau cov kua qaub).
Ntu 2 ntawm 3: Ua Ntawv Thov Acid
Kauj Ruam 1. Hneev tag nrho thaj tsam
Txau dej rau ntawm lub pob zeb kom txog thaum ntub, tab sis tsis ua dej. Tsis tas li ntub cov khoom ib puag ncig, xws li ntoo, hav txwv yeem, phab ntsa, qhov rooj, qhov rooj thav duab, txee dai khaub ncaws, thiab ntaub pua tsev. Tshem cov rooj tog nyob ze.
- Cov pob zeb yuav tsum ntub dej tas li. Faib thaj tsam loj rau hauv ntu lossis qhov dej ib ntus los tiv thaiv kom nws qhuav.
- Tiv thaiv asphalt, phab ntsa ntub dej, thiab tarmac nrog cov ntaub yas poob lossis lwm yam teeb meem ntawm lub cev.
Kauj Ruam 2. Sprinkle rau ntawm cov kua qaub
Siv cov yas dej tuaj yeem nchuav cov kua qaub rau hauv cov pob zeb, nchuav qis rau hauv av. Ua haujlwm hauv ntu me, pib nrog thaj chaw ntsuas tsis pom. Cov yas tuaj yeem xeb, qee zaum hauv ib teev, yog li muaj ob peb lub poom hloov pauv tau yooj yim.. Nyeem daim ntawv qhia qhia kom txiav txim siab npaum li cas cov kua qaub los ntxiv, lossis siv cov lus qhia no:
- Sulfamic acid: 1 nkas loos kho tau 300 ft.2 qhob (1 liter rau 28 m2).
- Phosphoric acid: 1 nkas loos kho 500-2500 ft.2 (3.8 L rau 45-250 m2) thaum tshem cov pob zeb hauv av pov tseg.
- Muriatic acid: 1 nkas loos kho tau 45 ft.2 (4.5 L rau 5 m2).
Kauj Ruam 3. Txhuam cov kua qaub hla cov pob zeb
Txoj cai tom qab nchuav cov kua qaub, txhuam nrog cov laub rub los yog txhuam txhuam txhuam ntev kom kis tau cov kua qaub rau hauv ib txheej. Rau cov haujlwm loj, ib tus neeg tuaj yeem siv lub tshuab pem teb thaum lwm tus txhuam cov kua qaub rau hauv cov ces kaum thiab phab ntsa.
Nco ntsoov hauv av thiab cov khoom ib puag ncig tsis qhuav thaum koj tab tom thov kua qaub. Tej zaum koj yuav tsum tau hle lawv ntau zaus
Kauj Ruam 4. Cia cov kua qaub zaum ob peb feeb
Tos 5-10 feeb rau cov kua qaub los ua cov pob zeb ua ke. Yog tias koj tsuas yog tshem tawm cov pob zeb hauv av dawb, tos kom txog thaum koj pom lawv nqa tawm ntawm cov pob zeb (feem ntau tsuas yog ob peb feeb).
Ntu 3 ntawm 3: Ntxuav
Kauj Ruam 1. Yaug kom huv
Ua ntej cov kua qaub qhuav, txhuam tawm qhov seem uas seem nrog txhuam txhuam txhuam ntev thaum yaug nrog dej kom ntau. Tawm cov kua qaub ntev dhau tuaj yeem ua rau koj cov pob zeb puas.
Kauj Ruam 2. Tshem tawm cov kua qaub
Sib tov 1 khob ntawm ci dej qab zib, txiv qaub hauv vaj, lossis ammonia hauv tsev hauv 1 nkas loos dej (kwv yees li 250 mL hauv 4 L), lossis ua raws daim ntawv qhia qhia ntawm cov khoom ua kom tsis muaj kua qaub. Khawb qhov no hla lub pob zeb thiab cia zaum tsawg kawg kaum feeb kom ntseeg tau tias tag nrho cov kua qaub nruab nrab. Them nyiaj tshwj xeeb rau cov ntug thiab ib qho qis hauv pob zeb.
Txij ntawm no mus, cov pob zeb ua ke yuav tsum muaj kev ntxhib los mos zoo ib yam li cov xuab zeb zeb zeb nruab nrab. Yog tias cov pob zeb ua kom du dua qhov no, lossis yog tias tseem muaj cov ntxhia dawb tso, thov siv cov kua qaub dua zaum ob
Kauj Ruam 3. Yaug ob peb zaug
Txawm tias tom qab cov kua qaub nruab nrab, kua tso rau saum npoo av tuaj yeem tawm dawb, hmoov seem tom qab nws qhuav. Txau cov pob zeb nrog dej, txhuam, thiab rov ua dua ob peb zaug los tiv thaiv qhov no tsis txhob tshwm sim. Nqa cov dej yaug zaum kawg nrog lub khw muag khoom lossis txhuam nws mus rau hauv lub qhov dej.
- Siv lub hose los yaug cov kua qaub es tsis yog lub tshuab ntxhua khaub ncaws. Cov no tuaj yeem ua kua qaub tob rau hauv cov pob zeb.
- Yuav kom muaj kev nyab xeeb, kuaj zaum kawg yaug dej nrog pH kuaj kab txaij. Yog tias nws qis dua 6.0, muaj cov kua qaub ntau dhau thiab hauv av xav tau yaug ntau dua. (Tsawg tsawg zaus, qhov tshwm sim saum 9.0 txhais tau tias koj tau ntxiv ntau qhov nruab nrab nruab nrab.)
Kauj Ruam 4. Ntxuav cov kua qaub uas seem
Yog tias koj muaj cov kua qaub uas tshuav, ncuav nws maj mam mus rau hauv lub thoob loj uas tau ntim ib nrab nrog tib qho kev daws teeb meem uas koj tau siv ua ntej. Maj mam ua rau ntau cov kua qaub thiab cov hauv paus raws li xav tau kom txog thaum sib tov nres fizzing. Thaum nruab nrab, koj tuaj yeem nchuav nws rau hauv lub dab dej lossis cua daj cua dub. Hose tawm ib qho khoom siv lossis khaub ncaws uas yuav tau kov cov kua qaub.
Yog tias koj tsis muaj phiaj xwm rau so ntawm cov kua qaub ntshiab, koj yuav xav muab pov tseg ib yam nkaus. Cov kua qaub nyob hauv qhov chaw khaws cia tuaj yeem ua rau muaj kev phom sij loj vim cov pa luam yeeb thiab muaj kev pheej hmoo ntawm nchuav
Yees duab - Los ntawm kev siv qhov kev pabcuam no, qee cov ntaub ntawv yuav raug muab qhia rau YouTube
Lub tswv yim
- Siv tus pab yog koj ua tau. Cov txheej txheem yuav txav nrawm dua yog tias koj tuaj yeem txhuam cov plag tsev thaum lwm tus neeg ua kom lub qhov dej mus.
- Cia hauv av kom qhuav tsawg kawg ob hnub ua ntej koj siv cov txheej (ntev dua nyob rau hauv qhov chaw ntub, txias, lossis qhov cua tsis zoo). Txawm hais tias lub ntsej muag zoo li qhuav, ya raws hauv qab tuaj yeem cuam tshuam nrog txheej.
Lus ceeb toom
- Tsis txhob ntxiv dej rau cov kua qaub. Ib txwm ntxiv cov kua qaub rau hauv dej txhawm rau tiv thaiv cov kua qaub txaus ntshai, tom qab ntawd sib tov cov tshuaj maj mam.
- Khaws tag nrho thaj chaw ntub thoob plaws txheej txheem. Qhov no pab khaws cov kua qaub los ntawm kev puas tsuaj cov ntaub ntawv tas mus li. Muriatic acid yuav tsis tsuas yog noj tam sim ntawd ntawm cov pob zeb, nws yuav ua rau hlau, ntoo thiab cov khoom siv hluavtaws zoo li ntaub pua plag.
- Khaws menyuam thiab tsiaj tawm ntawm qhov chaw.
