Chelate, chelate inoumbwa ne chelating agents, inobva pashoko rechiGiriki Chele, rinoreva crab claw.Chelates akafanana nembanje dzegakanje dzakabata ayoni esimbi, ayo akagadzikana zvakanyanya uye ari nyore kubvisa kana kushandisa ayaoni esimbi.Muna 1930, chelate yekutanga yakagadzirwa muGermany - EDTA (ethylenediamine tetraacetic acid) chelate yekurapa varwere vane heavy metal poisoning, uye ipapo chelate yakagadziridzwa uye inoshandiswa kune zuva nezuva kugeza makemikari, zvokudya, indasitiri uye mamwe maapplication.
Parizvino, ivo vakuru vanogadzira chelating agents munyika vanosanganisira BASF, Norion, Dow, Dongxiao Biological, Shijiazhuang Jack uye zvichingodaro.
Nharaunda yeAsia-Pacific ndiyo musika wakakura kwazvo wevamiriri vechelating, ine inopfuura 50% mugove uye inofungidzirwa musika saizi inodarika US $ 1 bhiriyoni, ine maapplication akajairika mukuchenesa, kurapwa kwemvura, kuchengetwa kwemunhu, mapepa, chikafu uye zvinwiwa maindasitiri. .
(Molecular chimiro che chelating agent EDTA)
Chelating agents anodzora simbi ions nekucheka ma-multi-ligands nesimbi ion complexes kugadzira chelates.
Kubva pane iyi nzira, zvinogona kunzwisiswa kuti mamorekuru akawanda ane akawanda-ligand ane akadaro chelation kugona.
Imwe yezvakanyanya kufanana ndeye EDTA iri pamusoro, iyo inogona kupa 2 maatomu enitrogen uye 4 maatomu eokisijeni ecarboxyl kuti ashande pamwe nesimbi, uye anogona kushandisa 1 molecule kusunga zvakasimba iyo calcium ion inoda 6 kubatanidzwa, ichigadzira chigadzirwa chakanyatsogadzikana chine zvakanakisa. chelation kugona.Zvimwe zvinowanzoshandiswa chelators zvinosanganisira sodium phytate yakadai se sodium gluconate, sodium glutamate diacetate tetrasodium (GLDA), sodium amino acids yakadai semethylglycine diacetate trisodium (MGDA), uye polyphosphates uye polyamines.
Sezvatinoziva tese, ingave mumvura yepombi kana mumvura yakasikwa, mune calcium, magnesium, iron plasma, aya maion simbi mukupfumisa kwenguva refu, achaunza zvinotevera zvinokonzeresa muhupenyu hwedu hwezuva nezuva:
1. Mucheka hauna kucheneswa zvakanaka, zvichiita kuti chikero chigadzirwe, chiomese uye chisvibe.
2. Hapana akakodzera kuchenesa mumiririri panzvimbo yakaoma, uye chiyero deposits
3. Scale deposits mu tableware uye glassware
Kuoma kwemvura kunoreva zviri mukati me calcium uye magnesium ions mumvura, uye mvura yakaoma inoderedza kugeza.Muzvigadzirwa zve detergent, iyo chelating agent inogona kuita ne calcium, magnesium nedzimwe simbi ions mumvura, kuitira kupfavisa mhando yemvura, kudzivirira calcium uye magnesium plasma kubva pakuita pamwe neanoshanda agent mune detergent, uye kudzivirira kukanganisa maitiro ekugeza. , nokudaro kuvandudza kushanda kwechigadzirwa chekugeza.
Mukuwedzera, chelating agents vanogonawo kuita kuti kuumbwa kwe detergent kuwedzere kugadzikana uye kusakanganiswa nekuora kana kupisa kana kuchengetwa kwenguva yakareba.
Kuwedzerwa kwechelating agent kune yekuwachira detergent kunogona kuwedzera simba rayo rekuchenesa, kunyanya munzvimbo dzinoshandiswa kuchenesa zvakanyanya nekuoma, zvakadai sekuchamhembe, kumaodzanyemba kwakadziva kumadokero nedzimwe nzvimbo dzine kuoma kwemvura, chelating agent inogonawo kudzivirira kusvibiswa kwemvura uye mavara. kubva pakugadzirisa pamusoro pemucheka, kuitira kuti detergent iwedzere uye inonamatira nyore nyore pamusoro pezvipfeko, kuvandudza maitiro ekugeza panguva imwe chete.Kuvandudza kuchena uye kupfava, intuitive performance haina grey uye yakaoma zvakaoma.
Zvakare mukuchenesa kwepamusoro pekuchenesa uye kuchenesa tafura, iyo chelating agent mune detergent inogona kuvandudza kuparara uye kuparadzira kugona kwe detergent, kuitira kuti tsvina uye chiyero zvive nyore kubvisa, uye intuitive performance ndeyekuti chiyero hachigone kuramba chiripo. kumusoro kunowedzera kujeka, uye girazi hariturike firimu remvura.Chelating agents vanogonawo kusanganisa neokisijeni mumhepo kuti vagadzire zvinhu zvakagadzikana zvinodzivisa kusvibiswa kwesimbi.
Uye zvakare, iyo chelating mhedzisiro yechelating agents pane iron ions inoshandiswawo mukuchenesa pombi yekubvisa ngura.
