izindaba

Izinhlelo zamanzi zezimboni zivame ukuba nezinkinga zokukala kanye nokugqwala, okuthinta ukusebenza kahle kanye nempilo yesevisi yemishini. Ngokuthuthuka kwezindinganiso zokwelashwa kwamanzi zezimboni, amakhemikhali okwelashwa kwamanzi azinzile futhi anobungani nemvelo asesetshenziswa kabanzi ekukhiqizeni kwesimanje.I-Etidronic Acid (i-Hydroxyethylidene Diphosphonic Acid, i-CAS: 2809-21-4)iyisilinganiso se-organophosphorus esisebenza kahle kakhulu kanye nesithiyo sokugqwala. Ihlanganisa imisebenzi ye-chelating, dispersing kanye ne-film-forming, esebenza njengendlela ehlukile ethembekile kune-phosphate yendabuko kanye nezithiyo zokugqwala ezinobuthi. Isetshenziswe kabanzi emanzini apholile ajikelezayo, imishini yamanzi ahlanzekile, amanzi enqubo yamakhemikhali kanye nezinye izinhlelo eziningi zezimboni.

I. Izakhiwo Eziyisisekelo Zomzimba NamakhemikhaliI-Etidronic Acid

I-Etidronic AcidItholakala ngokuthengisa ngezindlela eziwuketshezi neziqinile ukuze ivumelane nezidingo ezahlukene zokupakisha, ezokuthutha kanye nokulinganisa endaweni. I-Liquid HEDP iwuketshezi olucacile olungenambala noma oluphuzi olukhanyayo, kuyilapho i-solid HEDP ibonakala njengempuphu emhlophe noma ama-granule. Amazinga oketshezi lwezimboni agcina okuqukethwe okusebenzayo okungaphezu kuka-50%, kanti imikhiqizo eqinile emsulwa kakhulu ifinyelela ubumsulwa obungaphezu kuka-98% ngomswakama ophansi osele.

Inzuzo ebalulekile ye-HEDP isakhiwo sayo sama-molecule esizinzile ngaphandle kwezibopho ze-POP ezikwazi ukugeleza kalula. Ama-polyphosphate endabuko angaphili avame ukuwohloka emazingeni okushisa angaphezu kuka-60°C, okukhiqiza isikali sesibili kanye nemiphumela yokwelapha amanzi ebuthaka. Ngokuphambene nalokho, i-HEDP imelana nokugeleza kwamanzi ngaphansi kokusebenza kwesikhathi eside kokushisa okuphezulu, kanye nokushisa kokubola kokushisa okuphezulu kuno-200°C. Ingafakwa ngqo ekushiseni kwegumbi ngesimo soketshezi noma incibilike ngokushesha endaweni ngesimo esiqinile. Isixazululo samanzi se-Etidronic Acid esingu-1% sigcina i-pH ezinzile engu-2.0–3.0. Zombili izinhlobo zoketshezi neziqinile zibonisa ukuncibilika kwamanzi okuhle kanye nokuhlakazeka okufanayo ngaphansi kwezimo zokushisa kwamanzi eziguquguqukayo. Izixazululo zokusebenza ezixubile zihlala zizinzile ngaphandle kwemvula esobala noma ukuhlukaniswa phakathi kwemijikelezo yokusebenza evamile.

II. Izinzuzo Eziyinhloko: Izizathu ZokuthiI-Etidronic AcidIsikhundla Esizinzile Emakethe Yamakhemikhali Okwelapha Amanzi

1. Ukusebenza Kahle Okuthuthukisiwe Nokunciphisa Izindleko Zokusebenza Ezijwayelekile

I-Etidronic Acid ine-viscosity ephansi kanye nokuhambisana okuhle kakhulu kokuhlanganiswa, ixubana kahle nama-ejenti okuqopha ngaphambi kokwenza ifilimu, ama-dispersant kanye nezinye izithasiselo zokwelashwa kwamanzi ezivamile. Akukho mishini yokushisa edingekayo ukuze kulinganiswe nsuku zonke, kube lula ukusebenza kwesistimu futhi kwehliswe ukusetshenziswa kwamandla okusiza. Uma kuqhathaniswa nemikhiqizo evamile ye-polyphosphate, i-Etidronic Acid inganciphisa ukusetshenziswa kwamandla kwesistimu iyonke futhi yehlise umthamo osebenzayo ngaphansi kwezimo ezifanayo zokwelashwa. Ukuphila kwayo isikhathi eside ebhodweni kunciphisa kakhulu imvamisa yokufakwa kwesisombululo, inciphise umsebenzi wezandla kanye nokungcola kwamakhemikhali ngesikhathi sokusebenza okuqhubekayo isikhathi eside. Ngezinhlelo zamanzi ezijikelezayo ezinkulu kanye nemishini yokulinganisa okuzenzakalelayo, i-HEDP inikeza ukusebenza kokwelashwa okuzinzile nokungaguquguquki, isiza amafektri ukuthi azinzise ukuphathwa kwekhwalithi yamanzi nsuku zonke kanye nokunciphisa izindleko zokusebenza eziphelele.

2. Ukuvinjelwa Okuvelele Kwesilinganiso kanye Nokusebenza Kokuvikela Insimbi Kwesikhathi Eside

I-Etidronic AcidIsebenza ngezindlela ezimbili zokuqhekeka kwe-chelation kanye ne-lattice. Ibamba i-calcium yamahhala, i-magnesium kanye namanye ama-ion ensimbi akha izikali emanzini ukuze yakhe ama-chelate azinzile ancibilikayo, ivimbela ukwakheka kwe-crystallization kasawoti kanye nokufakwa. Okwamanje, iphazamisa ukukhula kwezakhiwo zesikali se-microcrystalline, ivimbela izendlalelo zesikali esiqinile nesincane ukuthi zinganamatheli ezindongeni zamapayipi nasezindaweni zokushintshana kokushisa. Ezindaweni zamanzi ezinobunzima obuphezulu, i-alkalinity ephezulu kanye ne-chloride ephezulu lapho izithibi zendabuko zilwela ukugcina ukuzinza, i-Etidronic Acid igcina imiphumela yokulawula isikali ethembekile.
Ngokuphathelene nokuvikelwa kokugqwala, i-HEDP Scale kanye ne-Corrosion Inhibitor zimunca ngokulinganayo ensimbini yekhabhoni nasezindaweni zensimbi engagqwali ukuze zakhe amafilimu avikelayo aqinile. Ifilimu ihlukanisa i-oxygen encibilikisiwe kanye nama-ion agqwali ekuthinteni izinsimbi zensimbi, inciphisa amazinga okugqwala kwe-electrochemical ngempumelelo. Emishinini esebenza isikhathi eside efana nama-heat exchanger, ama-boiler kanye namapayipi ajikelezayo, i-Etidronic Acid isiza ekunciphiseni ukugqwala kwemigodi kanye nokugqwala okufanayo, yandisa imijikelezo yesevisi yemishini futhi inciphise ukulungiswa okungalindelekile okubangelwa ukukala kanye nokugqwala.

3. Izici Ezinobungani Nemvelo kanye Nokuhambisana Nemithetho Yomhlaba Wonke

I-Etidronic Acid iyinto yokwelapha amanzi engenabo ubuthi obuphansi, engadala umdlavuza futhi ebolayo. Ivumelana nezindinganiso zemvelo zomhlaba wonke kanye nemininingwane yokuphepha emsebenzini. Azikho izingxenye eziyingozi ezikhishwayo ngesikhathi sokusetshenziswa, okudala izimo zokusebenza eziphephile kubasebenzi endaweni. Ngemva kokusetshenziswa, i-HEDP ayikhiqizi izinsalela ezinobuthi eziqhubekayo, ifanela izidingo ezivamile zokukhishwa kwamanzi amdaka ezimbonini. Imibhalo ejwayelekile efana ne-COA kanye ne-MSDS inganikezwa ukusekela ukulethwa okuzinzile kwamanye amazwe kanye nokwamukelwa kwamakhasimende.

III. Izimo Zokusetshenziswa OkuyinhlokoI-Etidronic Acid

Izuza ekusebenzeni kwayo okuphelele ekuvimbeleni isikali, ekuvimbeleni ukugqwala kanye nokuhlakazeka, i-Etidronic Acid isebenza njengesithasiselo esibalulekile ezinhlelweni zokwelashwa kwamanzi zezimboni ezahlukahlukene:

1. Amanzi Okupholisa Ajikeleza Izimboni (Isicelo Esiyinhloko): Afanelekela izitshalo zikagesi, izigayo zensimbi, izitshalo zamakhemikhali kanye nezinhlelo ezinkulu zokupholisa umoya eziphakathi. Ilawula ukukala kwe-carbonate, i-sulfate kanye ne-silicate futhi inikeza ukuvikelwa okuzinzile kokugqwala kwemishini yokujikeleza kwamanzi ejikelezayo isikhathi eside.

2. Ukulwa Nokugqwala Nokuzinziswa Kwekhwalithi Yamanzi Ezakhiweni Zokwakha: Kusetshenziswa ekuphathweni kwamanzi ajikelezayo kwamapayipi kamasipala, imigudu kanye namaphrojekthi okulwa nokugqwala kwesakhiwo, okusekela ukusebenza okuzinzile kwezinhlelo ezingangeni manzi kanye nezokulwa nokugqwala.

3. Amanzi Okupholisa Inqubo Yezimboni: Asetshenziswa ekubumbeni i-injection yezimoto, ekukhiqizeni ngogesi kanye nasezintanjeni zokukhiqiza imboni ezilula ukuze kuqiniswe ikhwalithi yamanzi okupholisa futhi kusekelwe ukukhiqizwa okuqhubekayo kwesisindo.

4. I-Auxiliary Eyezimboni Zokunamathela Nokumboza: Ithuthukisa izimo zamanzi ezijikelezayo ezinqubweni zokubopha, ukuvala kanye nokumboza, ithuthukisa ukuzinza kwenqubo iyonke.

5. I-Composite Material Auxiliary: Isiza izinhlelo ze-epoxy kanye ne-heavy-duty anti-corrosion ekuthuthukiseni ukuqina kwezinto kanye nokumelana namakhemikhali ngokusebenzisa izimo zokucubungula ezizinzile ezisekelwe emanzini.

IV. Iphethini Yokuphakelwa Komhlaba Wonke

Abakhiqizi bamakhemikhali baseShayina baletha okuzinzileI-Etidronic Acidukuhlinzeka ngobuchwepheshe bokukhiqiza obuvuthiwe, izinhlelo zokulawula ikhwalithi ezijwayelekile kanye nomthamo ongandiswa. Isekelwa yizinto ezithembekile zomhlaba wonke kanye nezinkomba zomkhiqizo ezincintisanayo, imikhiqizo ye-HEDP ithunyelwa eNingizimu-mpumalanga ye-Asia, eYurophu, eNyakatho Melika, eMpumalanga Ephakathi nakwezinye izifunda, ihlangabezana nezidingo zemakethe zamakhemikhali okwelapha amanzi ezimboni asezingeni eliphezulu.

V. Isiphetho

I-Etidronic Acidihlanganisa ukuvimbela okuzinzile kwezinga, ukumelana nokugqwala, ukuzivumelanisa nezimo kwemvelo kanye nokusetshenziswa kwezomnotho, ihambisana nomkhuba wokuthuthukiswa kokwelashwa kwamanzi ezimbonini zanamuhla. Njengendlela ehlukile ewusizo kunezindlela zokwelapha amanzi ezinobuthi zendabuko, isiza amabhizinisi ukuthi agcine ukusebenza kohlelo lwamanzi okuzinzile futhi athuthukise ukuphathwa kokukhiqiza kwansuku zonke. Ngokuthuthukiswa okuqhubekayo kwezidingo zokwelashwa kwamanzi ezimbonini, i-Etidronic Acid izogcina inani lokusetshenziswa elizinzile ezimweni ezahlukahlukene zezimboni.
