Ziziphi iingenelo zeselulosi?

I-Cellulose luhlobo lwe-cellulose ukuveliswa kunye nokusetyenziswa kwayo kuya kunyuka ngokukhawuleza. Yi-ether engeyiyo i-inorganic cellulose exutywe ne-ether eyenziwe kwikotoni esulungekileyo emva kokubola, isebenzisa i-propylene oxide kunye ne-methyl chloride njengee-etherification agents, kunye noluhlu lweempendulo. Iqondo lokutshintshwa ngokubanzi yi-1.2 ~ 2.0. Iimpawu zayo zihluke ngenxa yemilinganiselo eyahlukeneyo yamacandelo e-tert-butyl kunye namacandelo e-hydroxypropyl.

(1) I-cellulose iyanyibilika emanzini abandayo, kwaye kuya kuba nzima ukuyinyibilika emanzini abilayo. Kodwa ubushushu bayo begelatin kumanzi abilayo buphezulu kakhulu kune-carboxycellulose. Imeko yonyibiliko kumanzi abandayo ikwaphuculwe kakhulu xa kuthelekiswa necarboxycellulose.

(2) I-viscosity ye-cellulose ihambelana nobukhulu bobunzima be-molecular mass, kwaye ubukhulu be-molecular mass, buphezulu be-viscosity. Ubushushu buya kuchaphazela i-viscosity yayo, ukushisa kuphakama, i-viscosity iyancipha. Kodwa i-viscosity yayo ephezulu kunye nobushushu obuphezulu ayinabungozi kangako kune-carboxycellulose. Isisombululo saso samanzi sizinzile xa sigcinwe kwiqondo lokushisa.

(3) Ukugcinwa kwamanzi kunye ne-solubility ye-cellulose ilele kwisixa sayo sokongeza, i-viscosity, njl., kunye nesantya sokugcinwa kwamanzi phantsi kwexabiso elifanayo lokongeza liphezulu kune-carboxycellulose.

(4) I-Cellulose iyamelana ne-asidi kunye ne-alkali, kwaye isisombululo sayo sizinzile kakhulu kuluhlu lwe-pH = 2 ~ 12. I-anhydrous aluminium chloride kunye ne-lime slurry ayinayo impembelelo enkulu kwiipropati zayo, kodwa i-alkali inokukhawulezisa izinga lokunyibilika kwayo kwaye iphucule i-viscosity yayo. I-cellulose inokwethenjelwa kwiityuwa ze-asidi eziqhelekileyo, kodwa xa ukuxinwa kwesisombululo setyuwa kuphezulu, i-viscosity yesisombululo se-cellulose ivame ukunyuka.

(5) I-Cellulose ingasetyenziselwa kunye neepolymers ezinyibilikayo zamanzi ukwenza i-uniform kunye ne-high-viscosity isisombululo samanzi. Okufana ne-acrylic emulsion, i-tapioca starch ether, iglue yemifuno, njl.

(6) I-Cellulose inokumelana ne-enzyme enamandla kune-carboxycellulose, kwaye isisombululo sayo samanzi asinakuchithwa yi-enzymes kune-carboxycellulose.

(7) I-adhesion of cellulose kwisakhiwo sodaka lwesamente iphezulu kune-carboxycellulose.
