Kedu ụdị celloxyethythythythythythythythythythythythythyth (hEC)?

Hydroxyethythythythythythythythyth Cellulose (HEC) bụ polymer-soluble ogige enwetara site na ngbanwe kemịkal nke sellose eke. A na-ejikarị ya na mkpuchi, kemịkal kwa ụbọchị, ihe eji ewu na ubi ndị ọzọ. Dị iche iche nke hec dị iche iche na-ebuwanye site na parampat ndị dị ka ogo ogo (DS), MSL), viscosity, wdg.

1. Ọdịnaya site na ogo nke dochie

Oru nke nbanye (DS) na-ezo aka na ọnụọgụ nke otu hydroxyethyl na ngalaba glucose nke ọ bụla. Mgbanwe na DS ga-emetụta mbọ, viscosity na mpaghara ngwa Hec.
Ogo di ala nke Hec: ​​DS dị n'okpuru 1.0. Ogo dị ala nke Hec nwere obere sogbality ma na-ejikarị ya na mpaghara chọrọ otu usoro mmiri na-eguzogide mmiri, dịka ụlọ na ụfọdụ mkpuchi.
Ngwunye nke iji dochie anya HEC: DS dị n'agbata 1.0 na 2.0. Ofdị hec nwere ezigbo akụkụ mmiri na viscosity dị elu, a na-ejikarị ya na ngwaahịa kemịkal kwa ụbọchị (dịka ihe na-adịghị mma na ihe ịchọ mma), mkpuchi na emulsions.
Ogo di elu nke Odiwu: DS dị n'elu 2.0. Ofdị hec na-abụkarị sọsọ mmiri dị elu ma na-ejikarị nghọta na-achọ nghọta na viscosity dị elu, dị ka anya mmiri, ndị na-abawanye na ụlọ ọrụ nri, wdg.

Nchikota merlation (ms) na-ezo aka na ọnụọgụ nke otu hydroxyethyyyl nke ọ bụla, mana gụnyere mmeghachi omume ọtụtụ na-eme n'oge dochie mmeghachi omume. The dị elu nke MS bara uru, ka mma mmiri soldọ aka na mgbasa nke hec bụ n'ozuzu.
Nchikota merlation Hec: ​​ms erughị 1. Ofdị hec a nwere ọnụego nwayọ nwayọ ma nwee ike ịchọ okpomọkụ ma ọ bụ oge na-akpali ogologo oge. Ọ dị mma maka ngwa ndị chọrọ mgbasa ma ọ bụ tọhapụ.
Nchikota Merlation Hec: ​​MS dị n'agbata 1 na 2. O nwere ọnụego mgbasa ozi na-agafeghị oke na kemịlị kwa ụbọchị, mkpuchi, na owuwu.
Nnukwu mec: MS karịrị akarị karịa 2. Ọ nwere ngwa ngwa na-achọ ngwa ngwa, ma dịkwa mma maka ngwa ngwa ma ọ bụ ihe ngwọta na njikere ụfọdụ ọgwụgwọ.

3. Ọdịnaya nke viscosity
Viccosite nke HEC bụ ihe dị mkpa na-egosi na ọ dị mkpa na ngwọta, na-esitekwa na nsogbu (ịta) nke ihe ngwọta na ọnọdụ nha (dịka ọnụego shiur).
Viscosity HEC: viscosity na 1% ngwọta erughị 1000 MPA. Nleta viscosity dị mma maka ihe dị ka onye nnọchi anya Rhitalogy, na-ejikwa ya eme nri, ma na-ejikwa ngwaahịa kemịkal kwa ụbọchị, ụlọ ọrụ nri, na nkwadebe ọgwụ.
Viccosity Hec: ​​viscosity na 1% ngwọta dị n'etiti 1000 na 4000 MPA. A na-eji viscosity hercy na-ejikarị mkpuchi na mkpuchi, adhesives, na-ebipụta inks, yana iwu ụlọ ọrụ na-ewu ewu na njikwa rhiology.
Nleta viscosity High: viscosity na 1% ngwọta dị elu karịa 4000 mpaghara. A na-ejikarị viscssity hecscosir dị elu ma dịkwa elu, kwesịrị ekwesị maka mpaghara dị elu, dị ka mkpuchi dị elu, ngwa ngwa, na ụfọdụ ngwa ọrụ pụrụ iche.

Enwere ike ịhazi hec dịka ụdị anụ ahụ ya, nke na-emetụtakarị ngwa na njikwa ya.
Ngwuta ntụ ntụ: ụdị a na-ahụkarị, dị mfe ibufe na ụlọ ahịa. Ejiri ya na ngwa ọrụ mmepụta ihe na oge kemịkalụ nke ụbọchị, ọ dị mkpa ka a gwakọta n'ime mmiri iji mepụta ihe ngwọta.
Granula HEC: HEC HEC dị mfe iji aka karịa ka ọ na-agbaze ma belata nsogbu uzuzu ma dabara adaba maka mmepụta ụlọ ọrụ mmepụta ihe.
Ngwọta HEC: N'okpuru ụfọdụ ngwa dịgasị iche, nke nwere ike inye ya na ụdị, nke dabara adaba maka iji ya mee ihe ma na-ebelata na ngwaahịa na ngwaahịa ọgwụ.

E nwekwara ụfọdụ hecs nke gbanwetụrụlarị n'ụzọ ma ọ bụ mesoo ya iji gboo mkpa nke ngwa ndị akọwapụtara.
HERE HEC: Ọkpụkpụ HEC na-eme ka ọ dị mma site na ihe mgbochi kemịkal, ọ dịkwa mma maka oge na-achọ ike dị elu na ịdị anya.
A na-eme ka nsogbu na-agbanwe agbanwe (dị ka caryMyMation, phosphoryylition, wdg) na-arụ ọrụ, dị ka akụrụngwa antibacterial, nguzosi ike ma ọ bụ ngbasa ọkụ.
Gwakọta hEC: jikọta ya na ndị ọzọ dị omimi ma ọ bụ ihe arụ ọrụ iji bulie arụmọrụ ya zuru oke, dị ka ntinye nke ndị na-emekọ ọnụ.

As an important water-soluble polymer material, different types of hydroxyethyl cellulose (HEC) adapt to different application requirements through changes in degree of substitution, molar substitution, viscosity and physical form. Ghọta usoro iwu ndị a na - enyere aka ịhọrọ ngwaahịa hec dabara adaba na ngwa ndị bara uru iji nweta arụmọrụ kachasị mma na mmetụta. Ma na kemịkal kwa ụbọchị, ụlọ, mkpuchi ma ọ bụ ọgwụ, ihe eji eme ya maka ezigbo ahịhịa ya nke ọma, moisrizizi na ihe na-akpụ akpụ.
