Isi mmalite sitere n'okike nke cellose
Cellulose bụ otu n'ime polymers ọtụtụ nke ahịhịa dị n'ụwa ma nọ ebe na-anọ ugbu a na ngalaba cell nke osisi, ọkachasị na osisi, owu, flax na eriri ndị ọzọ. Ọ bụ ihe dị mkpa na osisi osisi ma na-enye ike na nkwụsi ike. Isi ihe nkiti nke cellulose bu ihe glucose, nke ejikọtara site na by-1,4-glycosididic na-etolite ogologo. Dị ka ihe okike polymese, cellulose nwere ezigbo anụ ahụ na kemịkalụ, na-eme ya ihe dị mkpa maka usoro dị iche iche.
Usoro nkwadebe nke hydroxyethyth Cellulose
Ọ bụ ezie na cellosuse n'onwe ya nwere ọtụtụ ihe mara mma, ebe ngwa ya bụ naanị otu a. Isi ihe kpatara ya bụ na cellulose enweghị slublity, karịsịa sonye na mmiri. Iji meziwanye ihe onwunwe a, ndị ọkà mmụta sayensị na-agbanwe cellose iji kwadebe ihe dị iche iche cellose. Hydroxyethythythythythythythythythythythythythythyth celluse bụ mmiri mkpụrụ cellulose euther nwetara site na ethoxyliting eke sellose site na mmeghachi kemịkal.
Na usoro nkwadebe dị iche iche, akpa cellulose bu ụzọ gbazee na alkali ngwọta, mgbe ahụ, a na-agbakwunye otlete oxide na usoro mmeghachi omume. Ethoxylation reaction of ethylene oxide and hydroxyl groups in cellulose occurs to generate hydroxyethyl cellulose. Ngbanwe a na - abawanye hydrophilicaty of cellulose ígwè, si otú ahụ na-eme ka mkpali ya na akụrụngwa viscosity na mmiri.
Isi mmalite anụ ụlọ
Ihe eji eme ihe eji eme ihe maka nkwadebe hydroxyethythythythythythythythythythyth, na isi mmalite nke cellulose gụnyere:
Osisi: Ihe mejupụtara mkpụrụ osisi cellulose dị elu, karịsịa na osisi coniferous na osisi sara mbara, ebe cellulose nwere ike iru 40% -50%. Osisi bụ otu n'ime ụzọ kachasị mkpa nke cellose na ụlọ ọrụ, karịsịa na mpempe akwụkwọ na mmepụta nke cellulose merivatives.
OTTTT: eriri owu na-eme bụ ihe mejupụtara na cellulose, na ọdịnaya cellulose na owu dị ihe karịrị 90%. N'ihi ịdị ọcha dị elu ya, a na-ejikarị eriri owu iji kwadebe ihe na-elivative.
Akụkụ akụ dị ka flax na hemp: eriri osisi ndị a na-aba ụba na cellulose, na n'ihi na ọkụ ndị a na-enwekarị ike ọrụ dị elu, ha nwekwara uru ụfọdụ na mmịpụta celluse.
Ihe mkpofu ubi: gụnyere ahịhịa, ọka ọka, ahịhịa, ahịhịa nwere ike ịmịpụta ya, na cellulose na-eme ka ọ dị ọnụ ala, na-enye ọgbụgba dị mfe ma na-eme ka ọ dị ọcha nke akụrụngwa .

N'ihi akụrụngwa pụrụ iche nke hydroxyethythyth cellulose, a na-eji ya n'ọtụtụ ubi. Ihe ndị a bụ ọtụtụ mpaghara ngwa:
A na-eji ụlọ ọrụ owuwu: mkpụrụ osisi celllose na-ewu ewu na ụlọ ọrụ dị ka nke na-ejigide ya na mmiri na-ejigide, gypsum na ihe ndị ọzọ, nke nwere ike ime ka ihe dị na mmiri rụọ ọrụ.
A na-eji ụlọ ọrụ na-arụ ọrụ kemịkalụ nke ụbọchị: na ngwaahịa nlekọta anụahụ ngwaahịa kemịkal kwa ụbọchị, a na-eji cellulose kwa ụbọchị, a na-eji cellosethy dị ka nke na-eme ihe dị ka nke na-eme ihe na nkwụsi ike.
A na-eji ihe osise na mkpuchi: na ụlọ ọrụ mkpuchi mkpuchi, na-eji cellosethyl cellulose dị ka ihe na-enweghị isi na Rhitalogy Contation iji melite ọrụ nke mkpuchi ma zere ịkacha ọrụ.
Enwere ike iji ubi ọgwụ: na nhazi ọgwụ, enwere ike iji cellosethyth cellose, na-a na-achụpụ gị maka mbadamba maka ọgwụ ntọhapụ na nkwụsi ike nke ọgwụ.
Ọ bụ ezie na hydroxyethythythythyth ọ bụghị ihe na-akpata ihe, akụrụngwa ya, cellosuse, na-adị n'ọtụtụ na osisi. Site na ngbanwe kemịkal, enwere ike ịgbanwe cellulose nwere ike ịgbanwe n'ime hydroxyethyth cellulose nwere arụmọrụ dị mma ma tinye ya n'ọrụ na ọrụ dị iche iche. Natural plants such as wood, cotton, flax, etc. provide a rich source of raw materials for the production of hydroxyethyl cellulose. Site n'ọgba aghara nke sayensị na teknụzụ na mmụba na ihe ị chọrọ, usoro imepụta nke mkpụrụ osisi hydroxyeths na-ebulikwa uru ọ bara na ya n'ọdịnihu.
