Akwan Titiriw a Wɔfa so Siesie Magnesium Hydroxide na Wɔde Di Dwuma

Wɔde magnesium hydroxide, sɛ nnuru a ɛho hia a wɔde yɛ nnuru a ɛnyɛ abɔde mu de no, di dwuma kɛse wɔ nneɛma a ogya ntumi nhyew, nnuru, nneɛma a atwa yɛn ho ahyia ho banbɔ, ne nneɛma afoforo mu. Ne ahosiesie ne ne di no fa mfiridwuma ho nimdeɛ atitiriw pii ho, na saa akwan titiriw yi a wobenya no yiye no ho hia kɛse na ama nneɛma no ayɛ papa na ayɛ adwuma yiye.

Wɔ ahosiesie ho no, ammonia kwan, lime kwan, ne electrolysis kwan no ne mfiridwuma mu akwan titiriw. Wɔde ammonia kwan no di dwuma kɛse esiane sɛnea ɛyɛ adwuma brɛoo na nneɛma a wɔyɛ no ho tew kɛse nti. Nneyɛe pH a wɔbɛhwɛ so no yɛ ahokokwaw titiriw-mpɛn pii no, ɛsɛ sɛ wɔma pH no kɔ so yɛ 9 ne 10 na ama wɔahwɛ ahu sɛ magnesium hydroxide no bɛtɔ sɛnea ɛsɛ na wɔakwati sɛ efĩ te sɛ magnesium carbonate bɛba. Ahoɔhare a wɔde bɛkanyan no nso ho hia yiye. Sɛ wɔkanyan no yiye (bɛyɛ 200-300 rpm) a ɛma ahwehwɛ nucleation yɛ pɛ na esiw nneɛma nketenkete a ɛboaboa ano no ano. Afei nso, ɔhyew a wɔhwɛ so nya ahwehwɛ so nkɛntɛnso tẽẽ, na ɔhyew a ɛba fam (40-60℃) boa ma wɔyɛ magnesium hydroxide a ne kɛse yɛ nanos a apete kɛse.

Wɔ dwumadie fã no, ahokokwaa ho hia titire wɔ ogya a ɛmma ogya ntumi nkɔ mu no mu. Magnesium hydroxide hwehwɛ sɛ wɔyɛ nsakrae wɔ ne soro (te sɛ stearic acid a wɔde kata so) na ama ɛne organic matrix no ahyia yiye; anyɛ saa a, mfiri a ɛwɔ ade no mu no bɛsɛe. Nnuru-grade magnesium hydroxide hwehwɛ sɛ wɔyɛ aseptic processing a ɛyɛ katee ne particle size control, mpɛn pii no wɔde airflow milling di dwuma de nya 2-5μm particles de di ahwehwɛde ahorow a ɛtra hɔ daa-release ho dwuma. Wɔ nneɛma a atwa yɛn ho ahyia ho banbɔ mu no, sɛ wɔde magnesium hydroxide di dwuma de ma nsu fĩ a acid wom nyɛ hwee a, nhyehyɛe ne sɛnea wɔde ka ho no nya pH nsakrae a ɛyɛ den no so nkɛntɛnso tẽẽ. Wɔkamfo kyerɛ sɛ wɔde batch ka ho na wɔakwati localized over-alkalinity.

Ɛho hia sɛ wɔhwɛ baabi a ɛhɔ yɛ kusuu bere a wɔde nneɛma sie na wɔde rekɔ no. Magnesium hydroxide tumi twetwe nsu kɛse na ɛnyɛ den sɛ ɛbɛboaboa ano na ɛhwere ne mmɔdenbɔ bere a ɛwɔ mframa a ɛyɛ nwini mu no. Saa akwan titiriw yi a wɔde bedi dwuma wɔ nhyehyɛe kwan so no betumi ama magnesium hydroxide a etu mpɔn ne sikasɛm mu mfaso atu mpɔn kɛse wɔ tebea horow mu.
