Nyob rau hauv lub neej niaj hnub, vim hais tias scale inhibitors muaj ntau yam kev siv, muaj ntau ntau yam xaiv los ntawm thiaj li yuav ua tau raws li kev xav tau kev pab. Raws li pH ntawm tus neeg sawv cev, lawv tuaj yeem muab faib ua acidic thiab alkaline, ob qho tib si tuaj yeem yaj cov av thiab cuam tshuam cov xwm txheej rau nws cov khoom. Yog li dab tsi yog qhov txawv ntawm acidic thiab alkaline scale inhibitors.
1. Scale inhibitors feem ntau yog acidic, thaum alkaline scale inhibitors yog ib yam khoom. Qhov sib txawv ntawm ob qhov lus dag hauv ntau hom dej nyoos siv. Acidity feem ntau yog siv rau hauv av, kais dej, dej zoo, thiab lwm yam; Alkalinity feem ntau yog siv rau cov dej saum npoo av, seawater desalination, dej dej, pas dej, thiab lwm yam.
2. Kev siv ntau ntawm acidic scale inhibitors yog vim qhov tseeb tias yog tias muaj kev nyiam rau calcium carbonate scaling hauv cov dej nyoos siv los ntawm cov neeg siv khoom ntawm qhov chaw, pH tus nqi ntawm cov dej inlet ntawm cov khoom siv rov qab osmosis yuav tsum tau hloov kho. yog acidic los tswj cov nag lossis daus ntawm calcium carbonate los ntawm cov dej uas muaj bicarbonate ions. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov kua qaub rau hauv ntau cov khoom siv los tswj cov txheej txheem ntawm kev tswj xyuas. Yog tias alkaline scale inhibitors tau siv dua nyob rau lub sijhawm no, nws yog qhov zoo rau kev tsim cov tshuaj calcium carbonate.
Thaum peb cuam tshuam nrog scaling phenomena, vim hais tias scale kuj muab faib ua acidic thiab alkaline, tab sis alkaline scale tej zaum yuav ntau dua, alkaline scale inhibitors kuj siv ntau zaus. Ntawm lawv, alkaline scale inhibitors tuaj yeem siv lub hauv paus ntsiab lus ntawm cov tshuaj tiv thaiv nruab nrab kom tshem tawm cov nplai, thaum tseem kho acidity thiab alkalinity. Ntawm qhov tsis sib xws, nws yog daim ntawv thov cov nyhuv ntawm acidic scale inhibitors.
