2. Ihe mgbakwunye usoro nke hydroxyethythythyth Cellulose
Nkwụsị zuru ezu na arụmọrụ, hydroxyethythyythythyethyethyethy cellulose na-agbasasịwo ma kposa site na usoro mbu tupu usoro agafee. Iji hụ na cellulose nwere ike rụọ ọrụ ya n'ụzọ zuru ezu, ọ na-atụ aro ka igbari ya na mmiri buru ụzọ, kama itinye ya ozugbo na mkpuchi. Usoro ahụ akọwapụtara dị ka ndị a:
Họrọ mmiri kwesịrị ekwesị: A na-eji mmiri eghe na-eji ya dị ka ihe mgbaze. Ọ bụrụ na enwere mgbakwụ ndị ọzọ nke ahịhịa na sistemụ mkpuchi, a na-agbanwekwa ọnọdụ ndị dị mkpa ka a gbanwee ya dabere na Njirimara nke ihe mgbaze.
Jiri nwayọ wụsa hydroxyethythythythythythythythythythythythythythy na-eji nwayọ wụsa hydroxyethythythym Cellulose ntụ ntụ mgbe ị na-akpali mmiri iji gbochie mmiri iji gbochie agglomeration. Ọsọ na-akpali akpali kwesịrị ịdị ngwa ngwa iji zere iwepu ọnụego mkpụrụ ndụ nke cellulose ma ọ bụ guzobere "colloids" n'ihi oke mmiri.
Igwe na-eguzosi ike: Mgbe ị ga-ahapụ hydroxythythythythythythythythythythyth na-akwụ ụgwọ oge (ọ na-abụkarị nkeji iri atọ ruo ọtụtụ awa) Oge na-efesa na-adabere ụdị mkpụrụ osisi celluse, ọnọdụ okpomọkụ na ọnọdụ na-akpali akpali.
Adjust the dissolution temperature: Increasing the temperature helps to accelerate the dissolution process of hydroxyethyl cellulose. A na-atụkarị aro ka ị chịkwaa ihe ọkụkụ ahụ n'etiti 20 ℃ -40 ℃. Oke okpomọkụ nwere ike ibute mmebi cellulose ma ọ bụ ihe ngwọta emebi.
Undedhazigharị uru nke ph uru nke ngwọta nke hydroxyethyth cellulose na-enwe njikọ chiri anya na uru ph uru nke ihe ngwọta. Ọ na - agbanwecha mma n'okpuru ọnọdụ abụọ ma ọ bụ nke dịtụ mma, nke nwere uru pH dị n'etiti 6-8. N'oge usoro a, enwere ike idozigharị uru site na ịgbakwunye amonia ma ọ bụ ihe ndị ọzọ dị ka achọrọ.
Dingtinye usoro celdroxyethythythythythyth na sistemụ mkpuchi mgbe mgbasa, gbakwunye ihe ngwọta nke mkpuchi. N'oge mgbakwunye, a ga-atụnye ya nwayọ ma kpalie gị oge iji hụ na ịgwakọta matriks nke ọma. N'oge ị gwakọta usoro, ọ dị mkpa ịhọrọ ọsọ na-akwado ya dị ka sistemụ dị iche iche iji gbochie sistemụ ahụ site na ịkọ nkọ n'ihi oke ọkụ.
Ime mgbanwe viscosity mgbe ịgbakwunye hydroxyethythythythythyhethythyethythythythyhethyth cellose, enwere ike ịchịkwa vieti ahụ site na idozigharị ego ahụ agbakwunyere. N'ozuzu, ego nke hydroxyethythythyth cellulose ejiri dị n'etiti 0.3% -1 (onye ikwu na ngụkọta nha nke mkpuchi), na mkpa ka a ga-edozi ya nke ọma dị ka usoro mkpuchi. Oke nke mgbakwunye nwere ike ibute ibu ma nwee oke vishSositse na ọnya na-adịghị mma, na-emetụta ịrụ ọrụ owuwu; Ọ bụ ezie na mgbakwunye ezughi oke nwere ike ọgaghị enwe ike ịrụ ọrụ nke Troning na nkwusioru.
A na-anwale onye na-eme mkpọtụ na ịdekọ na-agbakwunye hydroxyethythythythythythythythythythy na-eme, sag, akara ule na-echekwa observe the sedimentation of the coating after standing for a period of time, the viscosity change, etc., to evaluate the stability of hydroxyethyl cellulose.
3. CHARA EGO
Gbochie Agglomeration: N'oge usoro mgbasa, ihe dị mfe na - eme ka mmiri sie mmiri ma zaa ya, yabụ na ị na - eme ka e nwee usoro nke lumps. Nke a bụ njikọ igodo na arụmọrụ ahụ, ma ọ nwere ike emetụta ọnụego na otu.
Zere elu Shear Force: Mgbe ị na-agbakwunye cellose, ọsọ na-agbakwunye oke iji zere iji eriri akwara, na-ebute mbelata arụmọrụ ya. Na mgbakwunye, na mmepụta mkpuchi mkpuchi, ojiji nke akụrụngwa kwesịrị ka o kwere mee.
Consinuochi nke mkpofu: mgbe ịwọrọ hydroxyethythythythyth cellulose, mmiri ahụ ekwesịghị ịdị oke elu. A na-atụ aro ijikwa ya na 20 ℃ -40 ℃. N'okpuru ọnọdụ okpomọkụ dị elu, mkpụrụ osisi cellulose nwere ike imebi mmetụta na visce ọnọdụ ya.
Ngwọta Ngwọta: Ngwọta Hydroxyetholulose na-edozi ahụ niile kwesịrị ịkwadebe ma jiri ya ozugbo. Nchekwa ogologo oge ga-emetụta ọhụụ ya na nkwụsi ike ya. A na-atụ aro ya iji kwadebe ihe ngwọta achọrọ n'ụbọchị emepụta iji dozie arụmọrụ ya kachasị mma.
Ihe mgbakwunye nke hydroxyethythythythythyth ọ bụghị naanị usoro agwakọta dị mfe, kama ọ dịkwa mkpa ijikọ ya na usoro ndị na-arụ ọrụ iji hụ na akụrụngwa njigide ya nke ọma. N'oge mgbakwunye, toaa ntị na nzọụkwụ tupu ịchịkwa ọnọdụ okpomọkụ na uru Ph uru, yana ngwakọta zuru oke mgbe mgbakwunye. Nkọwa ndị a ga-emetụta ogo na nkwụsi ike nke agba ahụ.
