Scale inhibitors yog cov tshuaj additives siv los tiv thaiv nplai thiab nag lossis daus hauv cov khoom siv kho dej. Lawv tuaj yeem cuam tshuam cov crystallization ntawm cov ions sib txawv hauv dej, yog li tiv thaiv lawv los ntawm kev tso nyiaj thiab txhaws hauv cov khoom siv. Raws li lawv cov khoom siv tshuaj lom neeg thiab cov qauv kev ua haujlwm ntawm lub cev, cov nplai inhibitors tuaj yeem muab faib ua cov hom hauv qab no:
Phosphate scale inhibitors:Feem ntau yog tsim los ntawm phosphoric acid, polyphosphoric acid, thiab emulsified phosphates, tsim nyog rau kev tiv thaiv cov scaling thiab nag lossis daus ntawm cov ntxhia ntsev xws li calcium, magnesium, thiab silicon, kuj hu ua calcium agents.
Organic acid scale inhibitors:Feem ntau yog tsim los ntawm cov organic acids xws li citric acid, acetic acid, thiab oxalic acid, tsim nyog rau kev tiv thaiv kev scaling thiab nag lossis daus ntawm cov hlau ions xws li calcium thiab manganese, thiab tseem muaj cov nyhuv ntawm alleviating cov nyhuv ntawm ferrous oxide nyob rau hauv dej.
Corrosion inhibitors:Hom nplai inhibitor no feem ntau ua rau sab hauv phab ntsa ntawm cov kav hlau lossis cov khoom siv, uas tuaj yeem txhim kho cov hlau corrosion tsis kam rau oxides, hydroxides, thiab alkaline tshuaj, yog li tiv thaiv corrosion thiab tev ntawm cov yeeb nkab phab ntsa, thiab tseem tuaj yeem txo qhov scaling thiab deposition. hauv dej.
Inorganic ntsev scale inhibitors:Sodium sulfate, sodium phosphate, ammonium nitrate, chloride, thiab lwm yam yog cov khoom xyaw tseem ceeb, tsim nyog rau kev tiv thaiv cov deposition thiab scaling ntawm inorganic ntsev xws li magnesium thiab calcium.
Acrylic copolymer:Hom nplai inhibitor no feem ntau hu ua dispersant lossis polymer, thiab tsim nyog rau kev tiv thaiv nag lossis daus, tshwj xeeb tshaj yog silicates. Feem ntau, nws tuaj yeem siv ua ke nrog tus neeg sawv cev chelating los txhim kho cov nyhuv.
Thov nco ntsoov tias ntau hom scale inhibitors muaj qhov sib txawv ntawm kev siv scenarios, kev siv, thiab cov teebmeem, thiab yuav tsum tau xaiv raws li qhov xwm txheej tshwj xeeb. Hauv kev siv, cov txheej txheem kev khiav hauj lwm tseem ceeb yuav tsum tau ua raws, thiab cov kev siv kom raug thiab kev tiv thaiv kev tiv thaiv yuav tsum tau ua kom paub tseeb tias kev ua haujlwm ntawm cov khoom siv thiab kev nyab xeeb ntawm tus kheej.
