Menene fa'idodin cellulose?

Cellulose wani nau'in cellulose ne wanda samarwa da amfaninsa zai karu da sauri. Yana da ether wanda ba inorganic cellulose gauraye da aka yi daga auduga mai ladabi bayan kashewa, ta yin amfani da propylene oxide da methyl chloride a matsayin ma'aikatan etherification, kuma ta hanyar jerin halayen. Matsakaicin maye gaba ɗaya shine 1.2 ~ 2.0. Siffofinsa sun bambanta saboda mabanbantan rabbai na abubuwan tert-butyl da abubuwan haɗin hydroxypropyl.

(1) Cellulose yana narkewa a cikin ruwan sanyi, kuma zai yi wuya a narke a cikin ruwan zãfi. Amma zafinsa na gelatinization a cikin ruwan zãfi yana da girma fiye da na carboxycellulose. Hakanan yanayin narkewa a cikin ruwan sanyi yana inganta sosai idan aka kwatanta da carboxycellulose.

(2) Dankowar cellulose yana da alaƙa da girman ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar cuta, kuma mafi girman girman ƙwayar ƙwayar ƙwayar ƙwayar cuta, mafi girma da danko. Har ila yau, yanayin zafi zai shafi danko, zafin jiki ya tashi, danko yana raguwa. Amma babban danko da zafinsa ba su da illa fiye da carboxycellulose. Maganin ruwan sa yana da ƙarfi idan an adana shi a cikin ɗaki.

(3) Riƙewar ruwa da solubility na cellulose ya ta'allaka ne a cikin ƙarin adadinsa, danko, da dai sauransu.

(4) Cellulose yana da juriya ga acid da alkali, kuma maganinsa yana da tsayi sosai a cikin kewayon pH = 2 ~ 12. Anhydrous aluminum chloride da lemun tsami slurry ba su da wani babban tasiri a kan kaddarorin, amma alkali iya hanzarta narkewar kudi da kuma inganta ta danko. Cellulose yana dogara ga gishiri na acid na kowa, amma lokacin da maida hankali na maganin gishiri ya yi girma, danko na maganin cellulose yana kula da karuwa.

(5) Ana iya amfani da Cellulose tare da polymers masu narkewa da ruwa don samar da wani nau'i mai mahimmanci da kuma babban bayani na ruwa mai zurfi. Irin su acrylic emulsion, tapioca sitaci ether, kayan lambu manne, da dai sauransu.

(6) Cellulose yana da ƙarfin juriya na enzyme fiye da carboxycellulose, kuma maganinta na ruwa ba shi da yuwuwar narkar da shi ta hanyar enzymes fiye da carboxycellulose.

(7) Mannewar cellulose zuwa ginin siminti ya fi na carboxycellulose girma.
