Kedu otu esi elele ọdịnaya ash nke Hydroxypropyl Methylcellulose (HPMC)?

Nyochaa ọdịnaya ash nke Hydroxypropyl Methylcellulose (HPMC) gụnyere ịchọpụta pasentị nke ihe fọdụrụ inorganic fọdụrụ mgbe agbachara ihe ndị ahụ ọkụ.Nke a bụ usoro izugbe maka ịme nnwale ọdịnaya ash maka HPMC:

Ihe achọrọ:

1. Hydroxypropyl Methylcellulose (HPMC) sample
2. Ọkụ mfụfụ ma ọ bụ ọkụ ntụ ntụ
3. Crucible na mkpuchi (nke ihe inert dị ka poselin ma ọ bụ quartz mere)
4. Onye nrụpụta
5. Ntụle nyocha
6. Ụgbọ mmiri ọkụ (nhọrọ)
7. Tongs ma ọ bụ crucible ejiri

Usoro:

1. Atụ nke sample:
   • Tulee crocible efu (m1) na 0.1 mg kacha nso site na iji itule nyocha.
   • Debe ihe nlele HPMC amara ama (nke na-abụkarị gram 1-5) n'ime ihe mkpuchi ahụ wee dekọ nha jikọtara ọnụ nke sample na crucible (m2).
2. Usoro ịhịa aka n'ahụ:
   • Tinye crucible nke nwere ihe nlele HPMC n'ime ọkụ muffle ma ọ bụ ite ntụ.
   • Kpoo ọkụ ahụ nke nta nke nta ka ọ bụrụ okpomọkụ a kapịrị ọnụ (nke bụ 500-600 Celsius) ma debe okpomọkụ a maka oge a kara aka (na-emekarị awa 2-4).
   • Gbaa mbọ hụ na ọkụ zuru oke nke akụrụngwa organic, na-ahapụ naanị ntụ inorganic.
3. Ịtụ oyi na ịtụ:
   • Mgbe usoro ntu ahụ gasịrị, wepụ ihe mkpuchi ahụ na ọkụ ọkụ na-eji mkpịsị aka ma ọ bụ ihe eji eme ihe.
   • Tinye crucible na ihe dị n'ime ya n'ebe a na-ehicha ihe ka ọ dị jụụ ruo n'ime ụlọ.
   • Ozugbo a jụrụ ajụ, megharịa ihe mkpofu na ntụ ntụ (m3).
4. Mgbakọ:
   • Gbakọọ ọdịnaya ntụ nke ihe nlele HPMC site na iji usoro a: ọdịnaya Ash (%) = [(m3 - m1) / (m2 - m1)] * 100
5. Ntụgharị asụsụ:
   • Nsonaazụ enwetara na-anọchite anya pasent nke ọdịnaya ntụ inorganic dị na nlele HPMC mgbe ọkụ gbachara.Uru a na-egosi ịdị ọcha nke HPMC yana ọnụ ọgụgụ nke ihe mfọdu nke inorganic dị ugbu a.
6. Na-akọ:
   • Kpesa uru ọdịnaya ntụ yana nkọwa ọ bụla dị mkpa dị ka ọnọdụ nnwale, njirimara nlele, na usoro eji.

ndetu:

• Gbaa mbọ hụ na crucible na mkpuchi dị ọcha na enweghị mmetọ ọ bụla tupu eji ya.
• Jiri ọkụ muffle ma ọ bụ ọkụ na-ekpo ọkụ nwere ikike ịchịkwa okpomọkụ iji hụ na kpo oku otu na nsonaazụ ziri ezi.
• Jiri nlezianya jikwaa crocible na ihe dị n'ime ya ka ọ ghara ịlafu ihe ma ọ bụ mmetọ.
• Mee usoro ntụ ntụ na mpaghara ikuku dị mma iji gbochie ikpughe na ngwaahịa combustion.

Site n'ịgbaso usoro a, ị nwere ike ikpebi nke ọma ọdịnaya ntụ nke Hydroxypropyl Methylcellulose (HPMC) ma chọpụta ịdị ọcha na ịdị mma ha.
