Kedu ihe bụ akụrụngwa nke hydropylthyl methyl cellulose na hydroxyethyth cellulose?

1.thddypypylthyl methyl cellulose

HydroxypylthththththylcellloseỌ bụ ụdị mkpụrụ osisi cellulose nke mmepụta ya na oriri na-abawanye ngwa ngwa. Ọ bụ nke na-abụghị nke ionic cellulose mere site na owu nụchara anụcha, na-eji propylene oxide na methyl chloride dị ka onye na-eme ihe nkiri, site na usoro mmeghachi omume. Ogo nke dochie anya ya bụ 1.2 ~ 2.0. Njirimara ya agbanweela dabere na ọdịnaya methoxyl na ọdịnaya mmiri.

(1) hydroxypylthylththththyth na-agbanye mmiri oyi, ọ ga-ezute ihe isi ike na mmiri ọkụ. Ma ọnọdụ okpomoku ya na mmiri ọkụ dị elu karịa nke methy cellulose. A na-akwalitekwa ngụgụ na mmiri oyi na-akwalite ya na methy cellulose.

(2) (2) viscosity nke hydroxyl Methylcelllose metụtara oke ya, na ibu oke molecular, onye dị elu na viscosity. Ọnọdụ okpomọkụ na-emetụtakwa viscosity ya, dị ka ọnọdụ okpomọkụ na-abawanye, viscese belata. Agbanyeghị, mmetụta nke viscosity na ọnọdụ okpomọkụ ya dị ala karịa nke methy cellulose. Ngwọta ya kwụsiri ike mgbe echekwara na ụlọ okpomọkụ.

(3) Njikọ mmiri nke hydropyythylthythyth na-adabere na mgbakwunye ya, viscosity, na -achi anya ya n'okpuru otu mgbakwunye ahụ dị elu karịa nke methy cellulose.

(4) hydroxylthylthylthylthylthylthyllose bụ ọkaibe na acid na alkali, na ngwọta ya dị oke mma na oke nke pH = 2 ~ 12. Saustic soda na mmiri lime enweghị obere mmetụta na arụmọrụ ya, mana alkali nwere ike ịmịcha ọnụego ya ma nwekwuo ọhụụ. Hydroxypyl Methylcellose bụ nkwụsi ike na nnu, ma mgbe ịta nke nnu dị elu, viscosity hydroxypyl methylcellopy na-abawanye.

(5) hydypropyythylthyththyth polymers na-agbanye mmiri iji mepụta usoro viogeneous, dị elu. Dị ka mmanya polyvinyl, stachi ether, ihe oriri na akwukwo nri, wdg.

(6) hydroxylthylthylthylthylcelllose nwere ike iguzogide elu karịa methylcellose, na ihe ngwọta ya agaghị emebi emebi site na enzymes karịa methylcellose.

(7) Nchọpụta nke hydroxyppropyythylthylthllopse ka ịgba ọkụ dị elu karịa nke methylcellose.

2. Hydroxyethyth Cellose

A na-eme ya site na owu nụchara anụcha na alkali na-emeso Alkali, ma meghachi omume na Ethylene Oxide dị ka onye ọrụ Itherification na ọnụnọ nke Isopropanol. Ogo ya nke dochie anya ya bụ 1.5 ~ 2.0. O nwere hydrophilicy siri ike ma dịkwa mfe ịnabata mmiri.

(1) hydroxyethythyythythythythyth celluble na mmiri oyi, mana o siri ike igbari na mmiri ọkụ. Ngwọta ya kwụsiri ike na oke okpomọkụ na-enweghị gellling. Enwere ike iji ya ruo ogologo oge dị elu okpomọkụ na ngwa ọgụ ya dị ala karịa nke methy cellulose.

(2)Hydroxyethyth Cellusekwụsiri ike na acid na alkali, Alkali nwere ike mee ngwa ngwa mgbasa ya na mgbe ọ na-abawanye vicosity. Mgbasa ya na mmiri dị oke njọ karịa nke methy cellulose na hydroxypyl methyl cellulose.

(3) hydroxyethythyythythythythythyth cellulose nwere ezigbo mgbochi SAG dịịrị maka ngwa agha, mana ọ nwere oge azụ oge maka ciment.

(4) arụmọrụ nke celdroxyethyth se cel cellulose dị ala karịa nke ụlọ ọrụ methy sellose n'ihi ọdịnaya mmiri ya dị elu na ọdịnaya dị elu.

(5) Ihe omimi nke ok nke hydroxyethythyth cellulose dị oke mkpa. Na okpomọkụ nke ihe dị ka 40 Celsius C, Mildew nwere ike ime n'ime ụbọchị 3 ruo 5, nke ga-emetụta arụmọrụ ya.
