Hais txog cov dej tawv tawv rau ntawm Polished Memorials

1.Kev nkag siab txog Calcium Build Up ntawm Granite

Cov dej tawv muaj cov dej ntxhia, feem ntau calcium carbonate thiab magnesium bicarbonate. Thaum cov dej los nag, cov dej ntws los sis cov dej ntws thaum sawv ntxov tuaj rau ntawm lub tsev teev ntuj granite thiab tom qab evaporates, cov zaub mov no tau tso tseg raws li microscopic crystalline deposits. Nyob rau tib lub sijhawm, cov voj voog evaporation txuas ntxiv tsim cov txheej txheem ntawm calcification uas ua rau opaque thiab nyuaj rau tshem tawm. Cov txheej txheem Calcification tau nrawm dua hauv cov cheeb tsam uas muaj cov dej hauv av nyuaj lossis hauv toj ntxas uas siv cov tshuab dej tsis siv neeg. Tsis zoo li cov organic stains (moss lossis algae), calcification yog ntxhia -raws li thiab chemically bonds rau polished nto, yuav tsum tau kho tshwj xeeb es tsis yooj yim txhuam. Piv txwv li, tus kab ntsig no ua hauv G681 granite muaj ob qho tib si polished thiab flamed tiav, thaum nws tau stains, peb tuaj yeem siv oxalic acid kua los ntxuav qhov chaw.

2. Qhov txawv ntawm qhov tsaus ntuj thiab lub teeb pom kev pom pob zeb

Qhov pom kev cuam tshuam ntawm cov dej tawv tawv sib txawv heev nyob ntawm seb cov xim granite. Ntawm cov pob zeb tsaus nti xws li Dub, Imperial Dub, lossis Hlau Grey, calcification tshwm li cov xim dawb lossis lub teeb pom kev zoo - grey haze, rings, lossis streaking uas zoo sib xws nrog daim iav -zoo li polish. Txawm tias ib daim duab nyias nyias tuaj yeem ua rau lub pob zeb tsaus nti zoo li tsis saib xyuas thiab muaj hnub nyoog hauv lub hlis. Hloov pauv, ntawm lub teeb -xim granites xws li Pearl White, G603, los yog Kashmir Dawb, calcium deposits zoo li sib xyaw nrog lub pob zeb cov keeb kwm yav dhau los, ua rau lawv tsis tshua pom. Vim li no, peb feem ntau qhia peb cov neeg siv khoom kom kuaj xyuas lawv qhov chaw ua haujlwm nrog cov dej nyuaj kom pom zoo cov kev xaiv ntawm granite sib zog rau cov neeg siv kev txhawj xeeb txog kev tu lub sijhawm ntev, lossis muab cov lus qhia meej txog kev saib xyuas nrog txhua qhov tsaus nti -xim monument muag. Ntawm no yog ib qho piv txwv ntawm Dark Bahama Blue duab puab, cov neeg siv khoom yuav tsum tau ceev faj ntau dua hauv kev saib xyuas ntawm cov xuab zeb blasting.

3. Pom zoo cov txheej txheem ntxuav rau cov khw muag khoom

Thaum cov neeg siv khoom tsis txaus siab txog cov dej tawv stains granite monument nto, cov khw muag khoom yuav tsum ua raws li cov txheej txheem pov thawj no tsis yog siv cov tshuaj hnyav:

A. Pib nrog txoj kev maj mam - Siv cov ntaub mos mos microfiber nrog dej distilled thiab xab npum me me (pH-} nruab nrab) kom tshem tawm cov plua plav saum npoo thiab cov khib nyiab xoob. Tsis txhob siv cov ntaub qhuav, vim lawv tuaj yeem zom cov ntxhia hauv cov txhuam hniav.

B.Siv ib qho tshwj xeeb calcification tshem tawm - Siv cov khoom lag luam granite-kev nyab xeeb descaler uas muaj sulfamic acid los yog citric acid (diluted rau pH 3.5–4.0). Thov nrog ib daim txhuam cev mos, tawm rau 3-5 feeb, ces yaug kom huv si nrog dej distilled. Rov ua dua yog tias tsim nyog. Ceeb toom: Tsis txhob siv hydrochloric acid, vinegar, los yog tshuaj bleach -cov no yuav chemically etching polished nto mus tas li.

C. Thaum kawg polish thiab foob - Tom qab tshem tawm calcification, buff lub nto nrog granite polishing compound kom rov qab gloss, ces siv ib tug penetrating impregnating sealer kom txo tau cov dej tom ntej los ntawm 70-80%.

4. Cov lus qhia rau cov neeg siv kawg ntawm Kev Kho

Kev tiv thaiv ib txwm zoo dua rau kev kho dua tshiab. Raws li tus xa tawm thiab cov chaw tsim khoom, peb xav kom cov khw muag khoom muab qhov kawg - daim npav saib xyuas neeg siv nrog txhua qhov khoom xa tuaj. Cov lus qhia txog kev tu vaj tse tseem ceeb suav nrog:

A. So cov dej sawv ntsug ntawm lub monument nto tom qab los nag los yog dej siv ib daim ntaub mos chamois los tiv thaiv evaporation deposits.

B. Tsis txhob siv cov tshuaj tsuag tsuag ncaj qha rau lub pob zeb ---- kho lub taub hau lossis teeb tsa cov thaiv thaiv.

C.Clean txhua xyoo nrog pH- nruab nrab granite ntxuav es tsis tos kom pom calcification los txhim kho.

D.Tsis txhob siv lub tshuab ntxhua khaub ncaws siab ---- dej siab tuaj yeem yuam cov pob zeb hauv av kom tob rau hauv micro-qhov hws thiab tej zaum yuav ua rau cov ntawv carved erodes thaum lub sij hawm.
