Kodi polyanionic cellulose ndi polima?

Polyanionic cellulose (PAC) ndi polima, yofunika kwambiri m'mafakitale osiyanasiyana, makamaka pakubowola ndi kufufuza mafuta. Kuti timvetsetse kufunikira ndi mphamvu za cellulose ya polyanionic, tiyeni tiyambe kufufuza momwe imapangidwira, kugwiritsa ntchito, ndi zotsatira zake m'magawo osiyanasiyana.

Pakatikati pake, polyanionic cellulose ndi yochokera ku cellulose, polima wopezeka mwachilengedwe m'makoma a cellulose. Selulosi yokha ndi polysaccharide yopangidwa ndi mayunitsi a shuga olumikizidwa pamodzi ndi β(1→4) glycosidic bond. Kapangidwe kameneka kamapangitsa kuti cellulose ikhale yamphamvu komanso yosasunthika, zomwe zimapangitsa kuti pakhale gawo lofunikira lazomera. Komabe, chibadwa cha cellulose chikhoza kusinthidwa ndikuwonjezeredwa kuti chigwirizane ndi ntchito zosiyanasiyana zamafakitale, zomwe zimapangitsa kuti pakhale zotumphukira monga polyanionic cellulose.

Ma cellulose a Polyanionic amapangidwa kudzera mukusintha kwa mankhwala a cellulose, momwe magulu a hydroxyl (-OH) omwe amapezeka mu molekyulu ya cellulose amasinthidwa ndi magulu a carboxymethyl (-CH2COOH). Kusintha kumeneku kumapereka mawonekedwe a anionic ku msana wa cellulose, zomwe zimapangitsa kuti pakhale polima yokhala ndi zinthu za polyanionic. Digiri ya m'malo (DS) imatsimikizira kuchuluka kwa m'malo mwa carboxymethyl pamsana wa cellulose, kukhudza momwe ma polima amagwirira ntchito.

Chimodzi mwazinthu zofunikira kwambiri za polyanionic cellulose ndi m'makampani amafuta ndi gasi, makamaka pobowola madzi. Madzi akubowola, omwe amadziwika kuti matope, amagwira ntchito zosiyanasiyana pobowola, kuphatikiza mafuta, kuziziritsa, ndi kuchotsa zinyalala. Ma cellulose a Polyanionic amawonjezeredwa kumadzi obowola ngati viscosifier komanso wowongolera kutaya kwamadzi.

Monga viscosifier, polyanionic cellulose imapatsa mphamvu kumadzi obowola, kukulitsa luso lawo loyimitsa kudula ndikusunga chitsime. Kulemera kwa ma cell a polymer ndi chilengedwe cha anionic chimalola kuti ipange netiweki mkati mwamadzimadzi, kukulitsa kukhuthala komanso kupewa kugwa kapena kukhazikika kwa zolimba. Kuphatikiza apo, polyanionic cellulose imawonetsa kulolera bwino kwa mchere, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pobowola mchere wambiri pobowola kunyanja.

Kuphatikiza pa ntchito yake ngati viscosifier, polyanionic cellulose imagwira ntchito ngati chowongolera kutayika kwamadzimadzi m'madzi akubowola. Popanga keke yopyapyala yopyapyala pakhoma la chitsime, polima imathandizira kuchepetsa kutayika kwamadzi mumpangidwe, potero imasunga kuwongolera koyenera ndikupewa kuwonongeka kwa mapangidwe. Katunduyu ndi wofunikira pakuwongolera bwino pobowola ndikuchepetsa kuopsa kwa magwiridwe antchito.

Kupitilira gawo lamafuta ndi gasi, ma cellulose a polyanionic amapeza ntchito m'mafakitale ena osiyanasiyana, kuphatikiza mankhwala, chakudya, ndi zodzola. M'mapangidwe amankhwala, amagwira ntchito ngati binder, disintegrant, kapena viscosity modifier pakupanga mapiritsi ndi kuyimitsidwa pakamwa. M'makampani azakudya, cellulose ya polyanionic imagwiritsidwa ntchito ngati thickening agent, stabilizer, kapena emulsifier muzakudya kuyambira sosi ndi zovala mpaka mkaka ndi zakumwa. Kugwirizana kwake ndi chilengedwe komanso kusakhala ndi poizoni kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazinthu zosamalira anthu monga mafuta odzola, mafuta odzola, ndi ma shampoos, komwe imagwira ntchito ngati chowonjezera kapena kuyimitsa.

Polyanionic cellulose imakhala ngati polima yosunthika yokhala ndi ntchito zambiri m'mafakitale angapo. Makhalidwe ake apadera, omwe amachokera ku kusinthidwa kwa cellulose, amachititsa kuti ikhale yofunikira kwambiri m'magulu monga mafuta ndi gasi, mankhwala, chakudya, ndi zodzoladzola. Pamene kafukufuku ndi kupita patsogolo kwaukadaulo kukupitilira, kugwiritsidwa ntchito kwa cellulose ya polyanionic kukuyembekezeka kukulirakulira, zomwe zikuthandizira kukulitsa luso komanso kuchita bwino m'magawo osiyanasiyana.
