I-Chelate, i-chelate eyakhiwe ama-chelating agents, ivela egameni lesiGreki elithi Chele, elisho uzipho lwenkalankala.I-Chelates ifana nezinzipho zenkalankala eziphethe ama-ion ensimbi, azinze kakhulu futhi kulula ukuwakhipha noma ukusebenzisa la ma-ion ensimbi.Ngo-1930, i-chelate yokuqala yahlanganiswa eJalimane - i-EDTA (i-ethylenediamine tetraacetic acid) i-chelate yokwelapha iziguli ezinobuthi obunzima, bese i-chelate yasungulwa futhi isetshenziselwa ukugeza kwamakhemikhali nsuku zonke, ukudla, imboni nezinye izinhlelo zokusebenza.
Njengamanje, abakhiqizi abakhulu be-chelating agents emhlabeni bahlanganisa i-BASF, i-Norion, i-Dow, i-Dongxiao Biological, i-Shijiazhuang Jack njalonjalo.
Isifunda sase-Asia-Pacific siyimakethe enkulu kunazo zonke yama-chelating agents, enesabelo esingaphezu kuka-50% kanye nosayizi wemakethe olinganiselwa ngaphezu kwe-US $ 1 billion, nezinhlelo zokusebenza ezijwayelekile embonini yokuhlanza, yokuhlanza amanzi, ukunakekelwa komuntu siqu, iphepha, ukudla neziphuzo. .
(Isakhiwo se-molecule ye-ejenti ye-chelating EDTA)
Ama-Chelating agents alawula ama-ion ensimbi ngokuchela ama-multi-ligand awo ngama-ion complexes ensimbi ukuze akhe ama-chelates.
Kusukela kulo mshini, kungaqondwa ukuthi ama-molecule amaningi anama-multi-ligand anekhono elinjalo le-chelation.
Enye yezinto ezijwayeleke kakhulu i-EDTA engenhla, enganikeza ama-athomu e-nitrogen angu-2 nama-athomu angu-4 e-carboxyl umoya-mpilo ukuze asebenzisane nensimbi, futhi ingasebenzisa i-molecule engu-1 ukuze isonge ngokuqinile i-calcium ion edinga ukuhlanganiswa okungu-6, ikhiqize umkhiqizo ozinze kakhulu onobuhle obuhle kakhulu. ikhono le-chelation.Amanye ama-chelators avame ukusetshenziswa ahlanganisa i-sodium phytate efana ne-sodium gluconate, i-sodium glutamate diacetate tetrasodium (GLDA), ama-amino acid e-sodium afana ne-methylglycine diacetate trisodium (MGDA), kanye nama-polyphosphates nama-polyamines.
Njengoba sonke sazi, kungakhathaliseki ukuthi emanzini kampompi noma emanzini emvelo, kukhona i-calcium, i-magnesium, i-iron plasma, lezi ion zensimbi ekuthuthukisweni kwesikhathi eside, zizoletha imiphumela elandelayo ekuphileni kwethu kwansuku zonke:
1. Indwangu ayihlanzwanga kahle, ibangela ukubekwa kwesikali, ibe lukhuni futhi ibe mnyama.
2. Ayikho i-ejenti yokuhlanza efanelekile endaweni eqinile, namadiphozi esikali
3. I-Scale deposits ku-tableware ne-glassware
Ukuqina kwamanzi kubhekisela kokuqukethwe kwe-calcium ne-magnesium ions emanzini, futhi amanzi aqinile azonciphisa umphumela wokugeza.Emikhiqizweni yokuhlanza, i-agent e-chelating ingasabela nge-calcium, i-magnesium namanye ama-ion ensimbi emanzini, ukuze athambise izinga lamanzi, avimbele i-calcium ne-magnesium plasma ukuthi ingasabelani ne-ejenti esebenzayo ku-detergent, futhi igweme ukuphazamisa umphumela wokuwasha. , ngaleyo ndlela kuthuthukiswe ukusebenza kahle komkhiqizo wokuwasha.
Ukwengeza, ama-chelating agents angenza futhi ukwakheka kwe-detergent kuzinze futhi kungabi lula ukubola lapho kushisa noma kugcinwa isikhathi eside.
Ukwengezwa kwe-agent ye-chelating ku-detergent yokuhlanza izingubo kungathuthukisa amandla ayo okuhlanza, ikakhulukazi ezindaweni lapho umphumela wokugeza uthinteke kakhulu ngobulukhuni, njengenyakatho, eningizimu-ntshonalanga nezinye izindawo ezinobunzima obukhulu bamanzi, i-chelating agent ingavimbela futhi amabala amanzi namabala. kusukela ekuzinzeni phezu kwendwangu, ukuze okokuhlanza izingubo kungene kalula futhi kunamathele kalula ebusweni bezingubo, ukuthuthukisa umphumela wokugeza ngesikhathi esifanayo.Thuthukisa ubumhlophe nokuthamba, ukusebenza okunembile akumpunga kangako futhi yome kanzima.
Futhi ekuhlanzeni indawo eqinile kanye nokuhlanza i-tableware, i-ejenti ye-chelating ku-detergent ingathuthukisa ikhono lokuhlakazeka nokusabalalisa kwe-detergent, ukuze kube lula ukususa ibala nesikali, futhi ukusebenza okunembile ukuthi isikali asikwazi ukuhlala, ubuso busobala, futhi ingilazi ayilengi ifilimu yamanzi.Ama-Chelating agents angaphinde ahlangane nomoya-mpilo emoyeni ukuze enze izakhiwo ezizinzile ezivimbela i-oxidation yezindawo zensimbi.
Ukwengeza, umphumela we-chelating we-chelating ejenti kuma-ion ensimbi nawo usetshenziselwa ukuhlanza amapayipi ukuze kukhishwe ukugqwala.
