Ni izihe nyungu za selile?

Cellulose ni ubwoko bwa selile ifite umusaruro nogukoresha biziyongera vuba. Ni selile idasanzwe ya selulose ivanze ikozwe mu ipamba itunganijwe nyuma yo kuyikuramo, ukoresheje okiside ya propylene na methyl chloride nkibikoresho bya etherification, kandi binyuze mubitekerezo. Urwego rwo gusimbuza muri rusange ni 1.2 ~ 2.0. Ibiranga biratandukanye bitewe nuburinganire butandukanye bwibintu bya tert-butyl hamwe na hydroxypropyl.

(1) Cellulose irashobora gushonga mumazi akonje, kandi bizagorana gushonga mumazi abira. Ariko ubushyuhe bwa gelatinisation mumazi abira buri hejuru cyane ugereranije na carboxycellulose. Imiterere yo gusesa mumazi akonje nayo iratera imbere cyane ugereranije na carboxycellulose.

. Ubushyuhe nabwo buzagira ingaruka ku bwiza bwabwo, ubushyuhe burazamuka, ubukonje buragabanuka. Ariko ubukonje bwacyo bwinshi nubushyuhe bwo hejuru ntabwo byangiza kurusha karubasi ya selile. Igisubizo cyamazi cyacyo gihamye iyo kibitswe mubushyuhe bwicyumba.

(4) Cellulose irwanya aside na alkali, kandi igisubizo cyacyo kirahagaze neza murwego rwa pH = 2 ~ 12. Anhydrous aluminium chloride na lime slurry nta ngaruka nini bigira ku miterere yabyo, ariko alkali irashobora kwihutisha umuvuduko wayo no kunoza ububobere bwayo. Cellulose yizewe mumunyu wa acide isanzwe, ariko iyo ubunini bwumuti wumunyu mwinshi, ubwiza bwumuti wa selile bukunda kwiyongera.

. Nka emulion ya acrylic, tapioca krahisi ether, kole yimboga, nibindi.
