Tshuaj khib efflorescence yog ib qho kev tshwm sim hauv cov txheej txheem kev tsim kho, feem ntau yog tsim los ntawm cov khoom siv dawb lossis lwm yam khoom siv hauv tsev thiab ua kom muaj pa roj carbon dioxide lossis dej noo hauv huab cua. Efflorescence tsis yog cuam tshuam rau kev zoo nkauj ntawm lub tsev, tab sis kuj tseem yuav muaj qee yam cuam tshuam rau kev ua haujlwm ntawm cov khoom siv.
Ua rau cug cug efflorescence
Tshuaj khib efflorescence feem ntau yog los ntawm cov hauv qab no:
Muaj cov ntsev ntawm soluble: Maas, xuab zeb, xuab zeb, xuab zeb lossis lwm cov ntaub ntawv raw muaj qee qhov ntau ntawm cov ntsev soluble, xws li cov roj carbonates, sulfates lossis chlorides.
Kev ya raws tsiv teb tsaws chaw: Thaum lub cev tsiv teb tsaws: thaum lub sijhawm ua tawv tawv lossis tawv nqaij coj los ntawm cov ntsev ua haujlwm rau sab solillary kev txiav txim.
Cov txheej txheem ib puag ncig: thaum lub sijhawm tsim kho lossis siv cov av noo noo yuav ua rau lub caij nplooj zeeg thiab ntsev tshwj xeeb, tshwj xeeb hauv cov huab cua ntub.
Cov dej ntau dhau ntawm cov dej sib piv: Ntxiv cov dej ntau dhau thaum lub sijhawm tsim kho ntawm cov tshuaj khib nyiab ntawm lub tshuaj khib, ua kom yooj yim dua rau cov ntsev kom tsiv teb tsaws.
Kev kho tsis raug rau Deg: Tsis muaj kev tiv thaiv kom zoo lossis txo kev tiv thaiv nce qhov tau ntawm efflorescence.
Lub luag haujlwm ntawm hydroxypropyl methylcellulose (HPMC)
HydroxyPropyyl methylcellulose (HPMC)yog feem ntau siv cov khoom siv ntxiv ntxiv, siv nyob rau hauv collch, putty hmoov thiab lwm yam khoom siv qhuav-xyaw. Nws lub ntsiab ua haujlwm suav nrog:
Thickening cov nyhuv: Txhim kho cov dej khaws cia thiab viscosity ntawm cug tshuaj tua kab cug, tiv thaiv kom txhob muaj dej los ntawm kev nqus dej sai sai, thiab ntev dua lub sijhawm qhib.
Dej khaws cia: tswj kom ya raws nyob hauv tshuaj khib, txhawb cov xis tso pa taws, thiab txhim kho lub zog.
Txhim kho kev ua haujlwm zoo: txhim kho kom zoo nkauj thiab ua haujlwm ntawm cug kev tshuaj khib, ua kev tsim kho kom yooj yim dua.
Kev sib txheeb ntawm HPMC thiab Efflorescence
HPMC nws tus kheej yog cov inert organic compound uas tsis tau koom nrog kev nyiam cov tshuaj tsw qab ntawm cov xis thiab tsis muaj ntsev solule. Yog li ntawd, kev sib raug zoo ntawm HPMC thiab tshuaj khib efflorescence tsis ncaj, tab sis nws yuav cuam tshuam nrog efflorescence prenomenon hauv cov kev hauv qab no:
Dej retention nyhuv :hpmc tau txhim kho cov dej tshem tawm ntawm cug tshuaj khib thiab tuaj yeem txo cov dej tsiv teb tsaws. Cov xeeb ceem no tuaj yeem qeeb nrawm ntawm cov ntsev soluble tau coj mus rau saum npoo los ntawm dej rau ib qho, yog li txo qhov tshwm sim ntawm efflorescence.
Dej-Masent Piv: Cov nyhuv tuab ntawm HPMC tuaj yeem txo qhov kev tsim nyog ntawm cov dej khib nyiab ntawm kev tsim nyog thiab tsis ncaj qha txo txoj kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm efflorescence.
Cov nyhuv ntawm porosity: cug nrog HPMC ntxiv feem ntau muaj cov porosity qis, uas tuaj yeem cuam tshuam cov neeg tsiv teb tsaws chaw ntawm cov ntsev. Txawm li cas los xij, yog tias HPMC yog siv tsis raug, xws li kev faib tawm ntau lossis tsis sib xws, thiab yuav ua rau muaj kev sib txawv hauv zos, thiab tuaj yeem ua rau muaj kev sib txuam tag nrho, thiab yuav ua rau muaj kev sib tsoo ntawm efforscescence ntawm efflorescence.
Kev sib cuam tshuam ntawm kev tsim kho chaw tsim kho: nyob rau hauv cov av noo lossis ntev ntev, cov dej ua kom muaj txiaj ntsig zoo heev, uas muaj cov kev ua kom haum rau efflorescence. Yog li ntawd, thaum siv HPMC nyob rau hauv cov chaw noo, kev saib xyuas yuav tsum tau them rau cov piv thiab kev tsim kho.
Cov lus qhia rau kev daws teeb meem Efflorescence
Xaiv cov khoom siv raw zoo: siv cov alkali tsawgasas, ntxuav xuab zeb thiab huv si los txo cov khoom siv soluble hauv cov khoom siv raw.
Ua kom zoo rau cov qauv txheej txheem tsim: Siv Kimacell®Spm thiab lwm yam kev sib ntxiv, tswj kav dej sib piv, thiab txo cov dej noo noo, thiab txo cov dej noo noo, thiab txo cov dej noo noo, thiab txo cov dej noo noo, thiab txo cov dej noo noo, thiab txo cov dej noo noo, thiab txo cov dej noo kev khiav tawm.
Kev kho cov npoo hauv qab: Thov cov txheej txheej dej los yog anti-alkali sealant rau ntawm cov tshuaj khib nyiab kom tiv thaiv cov dej los ntawm kev nkag mus lossis ntsev los ntawm kev tsiv teb tsaws.
Kev tswj hwm ib puag ncig: sim ua kom tiav nyob rau hauv cov ntsuas kub haum thiab vaum kom tsis txhob muaj cultural nyob rau hauv ib puag ncig lim ib puag ncig ib puag ncig ntev.
Kev Tu Siab Li Qub: Rau cov neeg mob uas efflorescence tau tshwm sim, nws tuaj yeem ntxuav nrog cov accelute acid) thiab tom qab ntawd txoj kev tiv thaiv saum npoo muaj zog.
Qhov tshwm sim ntawm efflorescence hauv tshuaj khib tau tsis muaj kev sib raug zoo ncaj qha nrogHPMC, tab sis kev siv HPMC yuav cuam tshuam rau cov qib ntawm efflorescence los ntawm kev cuam tshuam cov dej khaws cia, porosity thiab kev ua haujlwm ntawm lub cug. Txhawm rau txo txoj kev pheej hmoo ntawm efflorescence, HPMC yuav tsum tau siv tsim nyog, thiab lwm yam kev ntsuas yuav tsum tau ua ke los ua ke los txhim kho kev tsim kho thiab kev tswj hwm ib puag ncig.
