Nkọwa ngwaahịa
Fumaric Acid dị n'ụdị kristal na-enweghị agba, dị n'ọtụtụ ụdị ero na anụ ehi ọhụrụ.Enwere ike iji fumaric acid mee ihe n'ichepụta resin polyester na-adịghị mma.Fumaric acid bụ nri acidulent eji ogologo oge n'ihi na ọ dịghị egbu egbu.Dị ka ihe mgbakwunye nri, Fumaric Acid bụ ihe oriri dị mkpa na nri anyị.Dị ka onye na-eduga ihe mgbakwunye nri na onye na-eweta ihe oriri na China, anyị nwere ike inye gị Fumaric Acid dị elu.
Ejiri ya dị ka acidulant, Fumaric Acid nwere ọrụ bacteriostatic na antiseptik.Enwere ike iji ya dị ka onye na-ahụ maka acidity, acidifier, thermal-oxidative iguzogide inyeaka, na-agwọ ngwa ngwa na ose.Ejiri ya dị ka ihe acidic nke ihe na-emepụta ihe, ọ nwere ike ịmepụta afụ ogologo na ọmarịcha.Enwere ike iji fumaric acid dị ka onye na-ahụ maka ịcha ọcha na anya ọgwụ.Na ụlọ ọrụ ọgwụ, a na-eji ya emepụta alexipharmic sodium dimercaptosuccinate na ferrous fumarate.A na-ejikwa fumaric acid na-emepụta resin polyester na-adịghị mma.
Ọrụ & Ngwa
