Incazelo Yomkhiqizo:
I-crystalline powder emhlophe.Incibilika emanzini futhi ikwazi ukuchela ngezinhlobonhlobo zama-ion ensimbi.
Isicelo:
(1) Phakathi kukasawoti we-EDTA, usawoti we-disodium ubaluleke kakhulu futhi uyi-ejenti ebalulekile yokuhlanganisa ama-ion ensimbi kanye nezinsimbi ezihlukanisayo, kodwa futhi nezinto zokuhlanza, insipho ewuketshezi, ama-shampoos, izifutho zamakhemikhali ezolimo, ukuxubha kanye nokulungisa izixazululo ukuthuthukiswa nokucutshungulwa kwezinto ezizwelayo ezinemibala, ama-ejenti okuhlanza amanzi, izilungisi ze-pH, ama-anionic coagulants, njll. Kuhlelo lokuqala lwe-redox lwe-polymerization yerabha ye-styrene-butadiene, i-disodium EDTA isetshenziswa njengengxenye ye-ejenti esebenzayo, ikakhulukazi ekuhlanganiseni. ama-ion ayoni kanye nokulawula izinga lokusabela kwe-polymerization.Inobuthi obuphansi, ne-LD50 yomlomo ye-2000 mg/kg kumagundane.Isetshenziswa njenge-ejenti ye-chelating yama-ion ensimbi.
(2) Ihlola i-calcium, i-magnesium, njll. Isetshenziswa embonini yezemithi, ukuthuthukiswa kombala, ukuncibilika kwezinsimbi ezingavamile, njll. Kuyi-agent eyinkimbinkimbi ebalulekile kanye ne-metal masking agent.
(3) Isetshenziswa njenge-ammonia carboxylate complexing agent ekunqumeni i-calcium, i-magnesium nezinye izinsimbi.Isetshenziswa njenge-ejenti yokufihla insimbi kanye nonjiniyela wombala.Ibuye isetshenziswe embonini yezemithi kanye nasekuncibilikisweni kwezinsimbi ezingavamile.
(4) Ibuye isetshenziswe njenge-antioxidant synergist ku-cosmetics futhi iyi-agent yensimbi ye-ion chelating, enomphumela ofanayo no-E DTA, kodwa inohlu olubanzi lwezinhlelo zokusebenza.Ingasetshenziswa ezintweni zokusetshenziswa zezimonyo eziqukethe ama-ion ensimbi alandelela futhi ekukhiqizeni nasekugcinweni nasekuthuthweni kwezimonyo lapho kusetshenziswa iziqukathi zensimbi.
Iphakheji:25 kgs/isikhwama noma njengoba ucela.
Isitoreji:Gcina endaweni engenawo umoya, neyomile.
IsikhuluOkujwayelekile:I-International Standard
