Kedu ihe dị iche n'etiti HPMC na HEC?

HPMC (HYDROXYLYLYLYLYLYLYLILLOS) na HEC (Hydroxyethyl Cellulose) bụ cellulose derivatives na-ejikarị ya na ụlọ ọrụ, akụrụngwa, wdg. Ọdịiche.

1. Ọdịiche na Memochi
HPMC na HEC bụ ihe ndị a na-emepụta mkpụrụ osisi cellulose (dị ka owu ma ọ bụ osisi pulp), mana ha dị iche na ndị nnọchi anya:

HPMC (HYDROXYLYLYLYLYLelllose): A na - enweta hpmc site na otu akụkụ ma ọ bụ dochie anya dị iche iche nke celdyl (-ch₃) na hydroxyl (oh) cellulose derivatives. Ogo nke dochie methyl na hydroxypyl ìgwè na-ekpebi ihe Njirimara nke HPMC.
HEC (Hydroxyethyl Cellulose): Hydroxyyth Cellulose nke e lere anya site na dochie otu ìgwè hydroxy nke celdrose na otu hydroxyethyl (nke bụ hydroxyethylition.
Ọdịiche ndị a na usoro kemịkalụ na-emetụta mmụọ ike ha, viscosity, na kemịkal ndị ọzọ na kemịkal ndị ọzọ.

HPMC: HPMC nwere ezigbo mmiri solubality ma enwere ike igbasasị na mmiri oyi iji mee ihe ngwọta viccolos. Ọ nwekwara ike ịgbasa ya na mgbatị ahụ ndị dị ka ethanol, acetone, wdg, mana ọsọ na ogo dị iche iche dabere na ogo dị mkpa. Akụkụ dị mkpa nke HPMC bụ na ọ na-agbaze mmiri oyi, ebe oge na-ekpo ọkụ na-aga n'ihu na gel mgbe ọ na-agbaze ma sie ike). Ngwongwo a di ezigbo nkpa n'ubi dika iwu na mkpuchi.

HEC: HEC na-agbasasịkwa na mmiri oyi, mana n'adịghị ka HPMC, hec anaghị aga na mmiri ọkụ. Ya mere, enwere ike iji HEC mee ihe n'olu okpomoku. HEC nwere nnata siri ike ma sie ike ma dịkwa mma maka iji ya na ngwọta nwere elecrolytes.

Visaty of the Hpmc na Hec dị iche iche na oke molecular ha, ha abụọ nwere ezigbo mmetụta dị mma na-enwe mmetụta dị iche iche:

HPMC: HPMC na-egosipụta Pseudoplastity (ntụgharị, Shear-Thinning) na ngwọta. Viccositions nke ngwọta HPMC na-ebelata mgbe ị na-abawanye na-agbasa ma ọ bụ brincity, wdg. Na gel ga-etolite na ụfọdụ okpomọkụ.

HEC: HEC lere nwere viscosity dị elu na akụrụngwa dị mma nke ukwuu na ọnụego Shear, na-egosipụta Njirimara Flandation New Newton (yae Shear na-eme ka ọ bụrụ ọnụego shier). Na mgbakwunye, ngwọta hic nwere obere mgbanwe viscosit na gburugburu nwere nnu na electrolytes, ma nwee ezigbo nnu. A na-eji ha eme ihe n'ọtụtụ ebe na-achọ nguzogide nnu, dị ka mmịpụta mmanụ na apịtị.

4. Ọdịiche na mpaghara ngwa
Ọ bụ ezie na enwere ike iji HPMC na HPMC dị ka ndị na-eme ihe nkiri, na-eme ihe nkiri, ihe nkiri, arụmọrụ ha na mpaghara ngwa iche iche iche:

Ngwa nke HPMC:
Industrylọ ọrụ owuwu: A na-eji HPMC mee ihe dị ka onye na-eme mkpọtụ na ebe a na-edebe mmiri na-ejide onwe ya n'ọhịa nke ụlọ ihe dị ka cent, ngwaahịa gypsum, na seramiiki tamiiki. Ọ na-eme ka ọrụ nke ngwa agha ahụ, na-agagharị, na ogologo oge nke ngwa agha.
A na-ejikarị ọgwụ ọgwụ: na ọgwụ, a na-ejikarị HPMC mee ihe dị ka ihe mkpuchi maka mbadamba na akụrụngwa maka nkwadebe ma tọhapụ ya. N'ime ụlọ ọrụ nri, a na-eji HPMC mee ihe dị ka ihe mgbakwunye nri, ọkachasị dị ka emunsufier, thinener, na mma.
Industrylọ ọrụ kemịkalụ nke ụbọchị: A na-eji ya dị ka ihe emulsion, dị omimi, na ihe nkiri na-echebe ihe na ngwaahịa ịchọ mma na ngwaahịa nlekọta onwe onye.

Ngwa nke HEC:
Mmịpụta mmanụ: Ebe ọ bụ na HEC nwere ndidi siri ike na nnu, ọ ka mma maka iji mmiri na-aga n'ihu na gburugburu mmiri na-eme ka ihe ndị dị elu dị elu iji melite akụrụngwa nke apịtị.
Ikike mkpuchi: A na-eji HEC dị ka nke na-agbada na mmachi uwe mkpuchi mmiri. Ọ nwere ike melite ahịhịa na-arụ ọrụ na arụmọrụ nke mkpuchi ma gbochie ndị na-ebu ụzọ.

5. Nsochi gburugburu ebe obibi na biocom
HPMC: A na-ejikarị HPMC na ubi ọgwụ n'ihi ezigbo biocombility na biodegrad. Ngwongwo ya na-enwu ọkụ na-enyekwa ya uru pụrụ iche na usoro ọgwụgwọ ọgwụ na-enweghị atụ. Ọzọkwa, HPMC bụ nononic, nke elektrọlytes na-enweghị ike, ma nwee ezigbo nkwụsi ike na mgbanwe ps.

HEC: HEC nwekwara ezigbo bayoloji na biodegrafity, mana ọ na-egosi oke nkwụsi ike na gburugburu nnu dị elu. Ya mere, hc bụ nhọrọ ka mma ebe achọrọ nnu na electrolyte, dị ka ọpụpụ mmanụ, wdgshore injinia, wdg.

6. Ọnụ ego na ọkọnọ
Ebe ọ bụ na a na-enweta HPMC na HPMC na Hec sitere na sellulose, a na-enye akụrụngwa kwụ chịm, mana n'ihi usoro mmepụta dị iche iche, ọnụ ahịa nrụpụta nke HPMC dị obere karịa nke HPMC. Nke a na-eme hec nke na-ejikarị ngwa na ngwa ndị dị ọnụ ahịa, dị ka ihe ndị na-ewu ụlọ, mmiri mmanụ, wdg.

HPMC na HEC bụ ihe dị mkpa cellulose. Ọ bụ ezie na ha dị iche na usoro kemịkalụ, ha abụọ nwere ọrụ dị ka nke na-eto eto, mmachi, njigide mmiri na ịse. N'ihe banyere nhọrọ ngwa a kapịrị ọnụ, HPMC nwere ọnọdụ dị mkpa na owuwu, ọgwụ na-eme ọgwụ na ụlọ ọrụ nri n'ihi ihe ngosi ya pụrụ iche; Ọ bụ ezie na HEC na-arụ ọrụ dị mkpa na ụlọ ọrụ Petroleum n'ihi ọmịiko nnu na nke ọnọdụ okpomọkụ nke ukwuu. Ọtụtụ uru na minks na mkpuchi mmiri. Dabere na ngwa ngwa dị iche iche, na-ahọpụta ihe kwesịrị ekwesị cellose mebere arụmọrụ na uru akụ na ụba.
