Otu esi emeziwanye ọsọ nhazi nke Carboxymethyl Cellulose

Ịkwalite ọsọ nhazi nke carboxymethyl cellulose (CMC) gụnyere ịkwalite nhazi, ọnọdụ nhazi, na akụrụngwa akụrụngwa iji kwalite mgbasa, hydration, na mgbasa nke CMC. Nke a bụ ọtụtụ ụzọ iji melite ọsọ nhazi nke CMC:

  1. Iji akara ule ngwa ngwa ma ọ bụ ngwa ngwa na-ekesa: Tụlee iji akara ule ngwa ngwa ma ọ bụ na-agbasa ngwa ngwa nke CMC nke a haziri maka hydration na mgbasa ngwa ngwa. Ndị a akara ule nwere nta urughuru nha na enwekwukwa solubility, ikwe maka ngwa ngwa nhazi na aqueous ngwọta.
  2. Mbelata nha nke urughuru: Họrọ akara ule CMC na nha nha nha, dị ka mma irighiri ihe na-eme ka mmiri dị ọcha ma gbasaa ngwa ngwa na mmiri. Egweri ma ọ bụ egwe ọka Filiks nwere ike n'ọrụ iji belata urughuru size nke CMC ntụ ntụ, na-emeziwanye ya configurability.
  3. Pre-Hydration ma ọ bụ Pre-Dispersal: Pre-hydrate ma ọ bụ tupu-agbasasị CMC ntụ ntụ na akụkụ nke mmiri a chọrọ tupu ị gbakwunye ya na isi ihe ngwakọta ma ọ bụ nhazi. Nke a na-eme ka ihe CMC na-eme ka ọ gbasaa ma gbasaa ngwa ngwa mgbe e webatara ya n'ime nnukwu ngwọta, na-eme ka usoro nhazi ahụ dịkwuo elu.
  4. Ngwakọta Ngwakọta kachasị mma: Jiri akụrụngwa ngwakọta dị elu dị ka homogenizers, igwe igwe colloid, ma ọ bụ ndị na-agba ọsọ dị elu iji kwalite mgbasa ngwa ngwa na hydration nke akụkụ CMC. Gbaa mbọ hụ na a na-ahazi akụrụngwa agwakọta nke ọma ma rụọ ọrụ na oke ọsọ yana ike maka nhazi dị mma.
  5. Okpomọkụ a na-achịkwa: Debe okpomọkụ ngwọta n'ime oke akwadoro maka hydration CMC, na-adịkarị gburugburu 70-80 Celsius maka ọtụtụ akara ule. Okpomọkụ dị elu nwere ike ime ka usoro hydration dịkwuo elu ma melite nhazi, ma ekwesịrị ịkpachara anya iji zere ikpo ọkụ ma ọ bụ gelation nke ngwọta.
  6. Ndozi pH: Gbanwee pH nke ngwọta na oke kacha mma maka hydration CMC, na-adịkarị obere acidic na ọnọdụ nnọpụiche. Ọkwa pH na-abụghị oke a nwere ike imetụta nhazi nke CMC na ekwesịrị ịhazi ya nke ọma site na iji acid ma ọ bụ ntọala dị mkpa.
  7. Njikwa ọnụ ahịa shear: Jikwaa ọnụ ahịa shear n'oge ngwakọta iji hụ na mgbasa nke ọma na hydration nke ihe CMC na-enweghị ịkpata oke iwe ma ọ bụ mmebi. Hazie ngwakọta agwakọta dị ka ọsọ agụba, impeller imewe, na ịgwakọta oge ebuli configurability.
  8. Ogo mmiri: Jiri mmiri dị elu nwere obere adịghị ọcha yana ihe siri ike gbazere iji belata ndabichi na hydration CMC na mgbasa. A na-atụ aro mmiri dị ọcha ma ọ bụ deionized maka nhazi kacha mma.
  9. Oge mkpasu iwe: Kpebie oke iwe iwe ma ọ bụ oge ịgwakọta oge achọrọ maka mgbasa ozi zuru oke na hydration nke CMC na nhazi. Zere ịgwakọta nke ukwuu, nke nwere ike ibute oke viscosity ma ọ bụ gelation nke ngwọta.
  10. Njikwa ogo: Na-eme ule njikwa mma oge niile iji nyochaa nhazi nke usoro CMC, gụnyere nha viscosity, nyocha nha nha, na nyocha anya. Gbanwee parampat nhazi dị ka achọrọ iji nweta arụmọrụ achọrọ yana nkwụsi ike.

Site n'itinye usoro ndị a, ndị na-emepụta nwere ike imeziwanye usoro nhazi nke carboxymethyl cellulose (CMC), na-eme ka mgbasa ngwa ngwa, hydration, na mgbasa na ngwa dị iche iche dị ka nri, ọgwụ, nlekọta onwe onye, ​​​​na ngwaahịa mmepụta ihe.
