Gịnị bụ uru nke cellulose?

Cellulose bụ ụdị cellulose nke mmepụta na ojiji ya ga-abawanye ngwa ngwa. Ọ bụ cellulose agwakọta nke na-abụghị inorganic nke sitere na owu a nụchara anụcha mgbe ọ nwụsịrị, na-eji propylene oxide na methyl chloride dị ka ihe etherification, yana site na mmeghachi omume dị iche iche. Ogo nke nnọchi bụ n'ozuzu 1.2 ~ 2.0. Njirimara ya dị iche iche n'ihi oke dị iche iche nke tert-butyl components na hydroxypropyl components.

(1) Cellulose na-agbaze na mmiri oyi, ọ ga-esikwa ike igbari na mmiri esi. Ma okpomọkụ gelatinization ya na mmiri esi mmiri dị elu nke ukwuu karịa nke carboxycellulose. Ọnọdụ mgbasa na mmiri oyi na-akawanye mma ma e jiri ya tụnyere carboxycellulose.

(2) Viscosity nke cellulose na-ejikọta na nha nke ihe dị n'akụkụ molekụla nke ikwu, na ka ọnyà molekul na-ebuwanye ibu, ka viscosity dị elu. Okpomọkụ ga-emetụtakwa viscosity ya, okpomọkụ na-ebili, viscosity na-ebelata. Ma elu viscosity ya na oke okpomọkụ adịghị emerụ ahụ karịa carboxycellulose. Ngwọta mmiri ya na-akwụsi ike mgbe echekwara ya na ụlọ okpomọkụ.

(3) Njide mmiri na solubility nke cellulose na-adabere na ego mgbakwunye ya, viscosity, wdg.

(4) Cellulose na-eguzogide acid na alkali, na ngwọta ya bụ nnọọ kwụsiri ike na nso nke pH = 2 ~ 12. Anhydrous aluminom chloride na lime slurry enweghị mmetụta dị ukwuu na akụrụngwa ya, mana alkali nwere ike mee ka ọnụego mgbaze ya dịkwuo ngwa ma melite viscosity ya. Cellulose bụ ihe a pụrụ ịdabere na ya na nnu acid nkịtị, ma mgbe ntinye nke ngwọta nnu dị elu, viscosity nke ngwọta cellulose na-ebuwanye ibu.

(5) Enwere ike iji cellulose mee ihe na-eme ka mmiri na-eme ka mmiri na-emepụta ihe ngwọta nke edo na nnukwu viscosity. Dị ka acrylic emulsion, tapioca starch ether, akwukwo nri gluu, wdg.

(6) Cellulose nwere nguzogide enzyme siri ike karịa carboxycellulose, na ngwọta mmiri ya adịchaghị agbaze site na enzymes karịa carboxycellulose.

(7) Adhesion nke cellulose na simenti ngwa agha ewu dị elu karịa nke carboxycellulose.
