1. Daim ntawv thov hauv Chelating Cleaning
Chelating agents, tseem hu ua complexing agents los yog ligands, siv cov complexation (kev sib koom tes) los yog chelation ntawm ntau yam chelating agents (xws li complexing agents) nrog scaling ions los tsim soluble complexes (kev sib koom ua ke) rau kev tu lub hom phiaj.
Surfactantsfeem ntau ntxiv rau chelating tus neeg saib xyuas kev tu kom txhawb cov txheej txheem ntxuav. Feem ntau siv cov inorganic complexing agents muaj xws li sodium tripolyphosphate, thaum nquag siv cov organic chelating agents muaj xws li ethylenediaminetetraacetic acid (EDTA) thiab nitrilotriacetic acid (NTA). Chelating tus neeg saib xyuas tsis yog tsuas yog siv rau kev ntxuav cov dej txias xwb tab sis kuj tau pom kev txhim kho tseem ceeb hauv kev ntxuav cov nplais nyuaj-rau-kua. Vim nws muaj peev xwm ua kom nyuaj lossis chelate hlau ions nyob rau hauv ntau yam nyuaj-rau-solve nplai, nws muaj kev tu siab.
2. Daim ntawv thov hauv Heavy Oil Fouling thiab Coke Fouling Cleaning
Hauv cov roj av refining thiab petrochemical cov nroj tsuag, cov khoom siv hluav taws xob sib pauv thiab cov kav dej feem ntau raug kev txom nyem los ntawm cov roj hnyav hnyav fouling thiab coke deposition, yuav tsum tau ntxuav tas li. Kev siv cov kuab tshuaj organic yog cov tshuaj lom heev, flammable, thiab tawg, thaum cov txheej txheem ntxuav alkaline tsis zoo tiv thaiv cov roj fouling hnyav thiab coke.
Tam sim no, hnyav roj fouling cleaners tsim nyob rau hauv domestic thiab thoob ntiaj teb yog feem ntau raws li nyob rau hauv composite surfactants, muaj ib tug ua ke ntawm ob peb nonionic thiab anionic surfactants, nrog rau inorganic builders thiab alkaline tshuaj. Composite surfactants tsis tsuas yog tsim cov teebmeem xws li ntub dej, nkag mus, emulsification, dispersion, solubilization, thiab foaming tab sis kuj muaj peev xwm nqus FeS₂. Feem ntau, cua sov kom siab tshaj 80 ° C yog xav tau los ntxuav.
3. Daim ntawv thov hauv Dej Txias Biocides
Thaum microbial slime muaj nyob rau hauv cov dej txias, uas tsis yog-oxidizing biocides yog siv, nrog rau tsawg-foaming nonionic surfactants li dispersants thiab penetrants, txhim khu kev ua hauj lwm ntawm cov neeg ua hauj thiab txhawb lawv nkag mus rau hauv lub hlwb thiab cov mucus txheej ntawm fungi.
Tsis tas li ntawd, quaternary ammonium ntsev biocides tau dav siv. Cov no yog qee cov cationic surfactants, uas feem ntau yog benzalkonium chloride thiab benzyldimethylammonium chloride. Lawv muaj zog biocidal zog, yooj yim ntawm kev siv, tsis muaj tshuaj lom, thiab tus nqi qis. Dhau li ntawm lawv cov dej num ntawm stripping slime thiab tshem tawm cov ntxhiab ntawm dej, lawv kuj muaj cov teebmeem corrosion inhibition.
Tsis tas li ntawd, biocides tsim los ntawm quaternary ammonium ntsev thiab methylene dithiocyanate tsis yog tsuas yog muaj qhov dav-spectrum thiab synergistic biocidal teebmeem tab sis kuj tiv thaiv kev loj hlob ntawm slime.
