1. Kushandiswa mukuchenesa kweChelating
Mishonga yeChelating, inozivikanwawo semishonga yecomplexing kana ligands, inoshandisa complexation (coordination) kana chelation yemishonga yakasiyana-siyana yechelating (kusanganisira mishonga yecomplexing) ine ma scaling ions kugadzira mishonga inonyunguduka (mishonga yecoordination) yekuchenesa.
Zvinoshandisa ma surfactantszvinowanzowedzerwa pakuchenesa chelating agent kuti zvikurudzire maitiro ekuchenesa. Zvinhu zvinowanzoshandiswa mu inorganic complexing zvinosanganisira sodium tripolyphosphate, nepo zvinhu zvinowanzoshandiswa mu organic chelating agents zvinosanganisira ethylenediaminetetraacetic acid (EDTA) uye nitrilotriacetic acid (NTA). Kuchenesa chelating agent hakungoshandiswi pakuchenesa masisitimu emvura inotonhodza chete asi kwakaonawo kukura kukuru mukuchenesa masikero akaoma kunyungudika. Nekuda kwekugona kwayo kuomesa kana kuchenesa ma ions esimbi mumasikero akasiyana akaoma kunyungudika, inopa kushanda kwakanaka kwekuchenesa.
2. Kushandiswa mukuchenesa mafuta akawanda uye Coke Fouling
Munzvimbo dzinochenesa peturu nemafuta, michina inochinja-chinja kupisa nemapaipi anowanzo sangana nemafuta akawanda anosvibisa uye anoisa coke, zvichida kucheneswa nguva nenguva. Kushandiswa kwezvinonyungudutsa zve organic kune chepfu yakawanda, kunopisa, uye kunoputika, nepo nzira dzekuchenesa alkaline dzakawanda dzisingabatsiri pakurwisa mafuta akawanda anosvibisa uye coke.
Parizvino, michina yekuchenesa mafuta akawanda yakagadzirwa munyika nepasi rose inonyanya kushandiswa pakugadzira zvinhu zvinosanganisa mafuta, zvinosanganisira zvinhu zvakasiyana-siyana zvinosanganisa mafuta zvisina ionic neanionic, pamwe chete nezvinhu zvisingasanganisike uye zvinhu zvine alkaline. Zvinhu zvinosanganisa mafuta hazvingogumiri pakunyorovesa, kupinda, kusanganisa, kupararira, kunyungudika, uye kuburitsa furo asi zvinewo simba rekutora FeS₂. Kazhinji, kupisa kusvika pamusoro pe80°C kunodiwa pakuchenesa.
3. Kushandiswa muMishonga yeBiocides yeMvura Inotonhorera
Kana hutachiona hwemabhakitiriya huchiwanikwa mumvura inotonhorera, mishonga isingaoxidizing biocides inoshandiswa, pamwe chete nemishonga isingaoxidizing inoburitsa furo shoma sezvinhu zvinoparadzira uye zvinopinda, kuwedzera mashandiro emishonga iyi uye kukurudzira kupinda kwayo mumasero uye mucus layer yefungus.
Pamusoro pezvo, mishonga ye quaternary ammonium salt biocides inoshandiswa zvakanyanya. Aya mamwe ma cationic surfactants, ayo anowanzo kuve benzalkonium chloride uye benzyldimethylammonium chloride. Anopa simba rakasimba re biocidal, nyore kushandisa, chepfu shoma, uye mutengo wakaderera. Kunze kwebasa rawo rekubvisa slime nekubvisa hwema mumvura, anewo mhedzisiro yekudzivirira ngura.
Uyezve, mishonga inogadzirwa ne quaternary ammonium salts ne methylene dithiocyanate haingori chete ine mhedzisiro yakakura uye inoshanda pamwe chete asiwo inodzivirira kukura kwetsvina.
