Mc bụ Methy Cellulose, nke a na-eme nke cellulose eat site na ịgwọ Alkali na Colon, jiri Methane chloride dị ka onye ọrụ ither, na ịga usoro mmeghachi omume. N'ozuzu, ogo nke nnọchi bụ 1.6 ~ 2.0, na solubity dịkwa iche na ogo dị iche iche nke dochie. Ọ bụ nke na-abụghị ionic ether.
(1) Ndozi mmiri nke methyl cellulose na-adabere na mgbakwunye ya, viscosity, urughuru na ọnụego ya. N'ozuzu, ọ bụrụ na mgbakwunye ego buru ibu, ọ dị obere, na viscosis buru ibu, ọnụ ọgụgụ njigide mmiri dị elu. N'etiti ha, ego nke mgbakwunye nwere mmetụta kachasị ukwuu na ụzọ mbelata mmiri, yana ọkwa viscosity abụghị nke dabara na ọkwa nke mmiri iji. Ọnụego mgbasa efe si na-adabere na ogo mgbanwe nke mkpụrụ osisi cellulose na urughuru. N'etiti ndị dị n'elu Cellers dị n'elu, methyl cellulose na hydroxyl methyl methyl cellulose nwere ọnụego mmiri dị elu.
(2) Methylcellose na-soluble na mmiri oyi, ọ ga-esikwa ike ịgbari na mmiri ọkụ. Ngwọta ya dị oke mma na mpaghara PH = 3 ~ 12. Ọ nwere ezigbo ndakọrịta na stachi, Guar chịm, wdg na ọtụtụ fromsactants. Mgbe ọnọdụ okpomọkụ na-erute okpomọkụ ahụ, gelation emee.
(3) Mgbanwe na ọnọdụ okpomọkụ ga-emetụta oke mmiri nke methyl cellulose. N'ozuzu, elu okpomọkụ, nke na-akacha njọ mmiri. Ọ bụrụ na mgbochi okpomọkụ karịrị 40 Celsius C, njigide mmiri nke methy cellulose ga-ebelata, na-emetụta oke owuwe ihe ngwa agha.
(4) methyl cellulose nwere mmetụta dị ukwuu na owuwu na ngwa agha. "Adhesion" ebe a na-ezo aka na ike ọrụ dị n'etiti ngwaọrụ ndị ọrụ onye ọrụ na mkpụrụ mgbidi, ya bụ, na-emegide ya na ngwa agha nke ngwa agha. Ndozi ahụ dị elu, nke a na-achọ ka ndị ọrụ na-ahụ maka ọrụ buru ibu, na owuru arụ ọrụ nke ngwa agha ahụ dara ogbenye. Methyl Cellulose na-eme na ọkwa na-agafe agafe ngwaahịa ether.
HPMC bụ hydropyyl methylcelllose, nke bụ mkpụrụ ndụ cellulose mere site na owu nụchara anụcha, na-eji propylene chloride dị ka ndị ọrụ iwe, na usoro mmeghachi omume. Ogo nke dochie anya ya bụ 1.2 ~ 2.0. Njirimara ya dị iche n'ihi ogo dị iche iche nke methoxy na ọdịnaya mmiri hydroxypypyl.
(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) viscosity nke hydroxyl Methylcelllose metụtara oke molecular ya, na ibu oke molecular ibu, onye dị elu na viscosity. Ọnọdụ okpomọkụ na-emetụtakwa viscosity ya, dị ka ọnọdụ okpomọkụ na-abawanye, viscese belata. Agbanyeghị, viscosity ya dị elu nwere obere okpomọkụ karịa methy cellulose. Ngwọta ya kwụsiri ike mgbe echekwara na ụlọ okpomọkụ.
(3) hydropopyythylthylthylthylcellose bụ ọkaibe na Ackali na Alkali, na Ngwọta ya dị oke mma na oke nke ph = 2 ~ 12. Saustic Sọsda na Wayo Waime enweghị obere mmetụta na arụmọrụ ya, mana alkali nwere ike ime ka ọpụpụ ya ma mee ka ọ dịkwuo ọhụrụ. Hydroxypyl Methylcellose bụ nkwụsi ike na nnu, ma mgbe ịta nke nnu dị elu, viscosity hydroxypyl methylcellopy na-abawanye.
(4) Ndobe mmiri nke hydropyythylthythyth na-adabere na mgbakwunye ya, viscosity, na -achi anya ya n'okpuru otu mgbakwunye ahụ dị elu karịa nke methy cellulose.
(5) hydroxyppropyythylthylthyl na-eji ọgwụ polmer na-adọkpụ na-etolite iji mepụta otu unifort na usoro visinity dị elu. Dị ka mmanya polyvinyl, stachi ether, ihe oriri na akwukwo nri, wdg.
(6) Nchọpụta nke hydroxypylthlthylthylcelllose ka ịgba ọkụ dị elu karịa nke methylcelllose.
(7) hydropopyythlthylthylthylcelllose nwere ike iguzogide elu karịa methylcellose, na ihe ngwọta ya agaghị emebi emebi site na enzymes karịa methylcelllose.
