Ingcaciso yeMveliso:
Umgubo omhlophe wekristale. Inyibilika emanzini kwaye ikwazi ukutshiza ngee-ion ezahlukeneyo zetsimbi.
Isicelo:
(1) Phakathi kweetyuwa ze-EDTA, ityuwa ye-disodium yeyona nto ibalulekileyo kwaye yeyona nto ibalulekileyo yokudibanisa i-ion zetsimbi kunye nokwahlula isinyithi, kodwa nakwizicoci, iisepha zolwelo, iishampu, izitshizi zemichiza yezolimo, i-bleaching kunye nokulungisa izisombululo zokucoca. uphuhliso kunye nokucutshungulwa kwezinto ezithintekayo kumbala, i-agent yokuhlanjululwa kwamanzi, i-pH adjusters, i-anionic coagulants, njl. Kwinkqubo yokuqalisa i-redox ye-polymerization ye-rabha ye-styrene-butadiene, i-disodium EDTA isetyenziswe njengenxalenye ye-agent esebenzayo, ngokukodwa ukudibanisa. i-ion ze-ferrous kunye nokulawula isantya se-polymerization reaction. Inetyhefu ephantsi, kunye ne-LD50 yomlomo ye-2000 mg/kg kwiimpuku. Isetyenziswe njenge-agent ye-chelating yee-ion zetsimbi.
(2) Ihlola i-calcium, i-magnesium, njl. Isetyenziswe kwishishini lamachiza, ukuphuhliswa kombala, ukunyibilika kweentsimbi ezinqabileyo, njl.
(3)Isetyenziswe njenge-ammonia carboxylate eyinkimbinkimbi yokumisela i-calcium, i-magnesium kunye nezinye izinyithi. Isetyenziswe njenge-agent yokufihla isinyithi kunye nomphuhlisi wombala. Ikwasetyenziswa nakwishishini loxubo-mayeza kunye nasekunyibilikiseni iintsimbi ezinqabileyo.
(4) Ikwasetyenziswa njenge-antioxidant synergist kwi-cosmetics kwaye i-agent ion chelating yensimbi, enefuthe elifanayo ne-EDTA, kodwa inoluhlu olubanzi lwezicelo. Ingasetyenziselwa kwizinto eziluhlaza zokuthambisa eziqukethe i-ion zetsimbi kunye nemveliso kunye nokugcinwa kunye nokuthutha izinto zokuthambisa apho kusetyenziswa izitya zetsimbi.
