Njirimara nke hydroxyethythyth cellulose

Hydroxyethythythythyth Cellulose (HEC) bụ nke a na-ahụkarị polymer na-esochi ya n'ọtụtụ ebe n'ọtụtụ ụlọ ọrụ dị iche iche. Ọ bụ mmeghachi omume kemịkalụ dị ka alkalization na ogo nke cellose eke. O nwere akụrụngwa anụ ahụ na kemịkal, na-eme ya ihe dị mkpa n'ọtụtụ ngwa.

1. Ọdịdị kemịkalụ na ịdị arọ molecular
Ngalaba nhazi nke hydroxyethythyth cellulose bụ cellulose settose dere nke glucose molecules. A na-ewebata otu ihe eji eme ya, a na-ewebata otu molecyl (-ch2CH2OH). N'ihi iwebata ndị a, hydroxyethythyth cellulose bụ hydrophilic ma nwee ịgha mkpụrụ karịa ịdị ọcha dị mma. Enwere ike ịgbanwe ngwa ngwa dị iche iche, (DS) na ndọtị mmiri (ms) nwere ike idozi, ms) nwere ike idozi, ya bụ na-emetụta ihe akụrụngwa igodo dị ka ịdọ aka, viscosity, na ike dị iche iche. N'ozuzu, oke molecular dị oke ọnụ, sitere na iri puku kwuru puku kwuru puku kwuru puku, nke na-eme ka ọ na-egosipụta ihe ndị dị iche iche na-egosi na ngwọta.

N'ihi ihe na-abụghị ionic na-abụghị nke ionic, hydroxyethy cellulose nwere ike igbari ma mmiri oyi ma na-ekpo ọkụ iji mepụta usoro vivoth vercolos. Ọnụego ya dabere na oke molecular, ogo nke dochie anya na okpomọkụ nke mmiri. Ofdị oke molecular dị elu nke hec ji nwayọọ nwayọọ nwayọ ma na-etolite ngwọta viscous, ebe oke oke egwu na-agbaze karịa ma na-emepụta ọhụụ. N'ihi ihe ngwọta ya, Hec nwere mmekọrịta dị mma maka mgbanwe na electrolytes ma nwee ike ịnọgide na-enwe ọnọdụ ya na mbara igwe (2-12).

Otu n'ime ihe ndị kachasị mara mma nke hec bụ ike ndị na-emekarị. Na ala dị ala (0,5% -2% nwere ike igosi mmetụta dị mkpa na-eme ka ọ dị mkpa, nke pụtara na ọnụego a na-abawanye, nke bara uru na ngwa ndị dị ka mkpuchi na emulsions. In addition, HEC can also work synergistically with other thickeners such as carboxymethyl cellulose (CMC) and xanthan gum to further improve the thickening effect or adjust the rheology.

4. Nkwụsi ike na ndakọrịta
HEC nwere ezigbo nkwụsi ike ma ọ bụghị kpamkpam iji mebie ma ọ bụ na-agbanwe kemịkalụ n'okpuru ọtụtụ ọnọdụ. Ngwọta ya nwere ike ịnagide nrujuanya nke electrolytes na a wider pranda, nke na-eme ka ọ kwụsie ike na gburugburu dị iche iche mgbagwoju anya. Na mgbakwunye, HEC dakọtara na ọtụtụ kemịkal ndị ọzọ dị ka nnuku ọkụ, wdg, yabụ a na-ejikarị sistemụ nrụpụta na mmetụta ndị na-arụsi ọrụ ike.

5. Ebe ntinye
N'ihi ihe ndị pụrụ iche ya, ejirila ya n'ọtụtụ mpaghara. Ihe ndị a bụ ụfọdụ ngwa ndị a na-ahụkarị:

A na-eji ihe eji eme ihe: na-ewu ewu, ihe osise, ube usety, wdg dị ka nke ukwu, ihe nkiri mbụ na mma iji meziwanye ihe owuwu ma mechaa ogo ngwaahịa.

A na-eji mmịpụta mmanụ: na ụlọ ọrụ mmanụ, a na-eji ya na nkwadebe olulu mmiri dị ka nke na-emejupụta na mmiri ga-eme ka ọ dị mma iji meziwanye rhiology nke apịtị ma gbochie mgbidi dị mma.

A na-ejikarị ya na ngwaahịa nlekọta onwe onye nkeonwe:

Industrylọ ọrụ nri: Ọ bụ ezie na ejiri obere obere, enwere ike iji hec dị ka ihe mgbakwunye nri iji dozie victy nri na uto nri.

6. Nchedo gburugburu na nchekwa
HEC bụ ekewasị sellulose jupụtara na ezi biodegrad dị mma, yabụ, ọ nweghị mmetụta na-emetụta gburugburu mgbe o jiri ya. Na mgbakwunye, a na-ahụ hec kemịkal dị mma ma na-ejikwa ya n'ọtụtụ ebe banye na ahụ mmadụ, dị ka ịchọ mma, ọgwụ na nri. Ka o sina dị, n'oge a na-emepụta ihe na-emepụta ihe ma jiri, iwu nchekwa dabara adaba na-egbochi mmeghachi omume na-enweghị isi nke enwere ike ibute ya site na inhalation ma ọ bụ ịkpọtụrụ oge.

7. Nchekwa ma jiri nlezianya
Ekwesịrị ịchekwa hydroxyethyth cellulose na ebe akọrọ gburugburu na nke dị jụụ iji zere mmiri mmiri na agagglomeration. Mgbe ị na-eji, ekwesịrị ịgbakwunye ya na mmiri nwayọ nwayọ ma ọ bụrụ na ịzere agglomeration nke mere site na ịgbakwunye nnukwu ego n'otu oge. N'otu oge ahụ, ebe ọ na-adịkarị mkpa iji gbanyụọ ya, ọ na-adịkarị mkpa ịhapụ ya nwa oge mgbe ị gbatịsịrị iji hụ na mgbasa ozi zuru oke na nke siri ike.

N'ihi oke mmiri ya dị mma, sie, kwụsiri ike na ndakọrịta, hydroxyethy cellulose abụrụla ihe mgbakwunye dị mkpa n'ọtụtụ ụlọ ọrụ mmepụta ihe. Na mmepe na-aga n'ihu nke teknụzụ, ngwa nke hec ga-aga n'ihu ịgbasa, na-enye ezigbo azịza maka ọrụ dị iche iche maka ụlọ ọrụ dị iche iche.
