Hydroxypropyl Methyl Cellulose Wowiritsa

Hydroxypropyl methylcellulose amagwiritsidwa ntchito ngati zopangira kupanga mafuta, omwe amatha kumaliza shuga, kuwongolera kuchuluka kwa zinthu zopangira, kuchepetsa otsalira a gawo lapansi mu msuzi wowotchera, kuchepetsa mtengo wamankhwala amadzi onyansa, ndikupanga mawonekedwe ake. ya hydroxypropyl methylcellulose yopindulitsa Imathandiza pakukhathamiritsa kwa mtanda, mtanda ndi njira zowotchera mosalekeza, kuteteza kusokoneza minofu ndi zovuta zokhudzana ndi chikhalidwe cha dilution;Komanso zothandiza mpheto ya nayonso mphamvu njira.

Hydroxypropyl methylcellulose, cellulose yaiwisi, imatha kukhala thonje woyengedwa, kapena kukhala zamkati zamatabwa.Iyenera kuphwanyidwa isanayambe kapena panthawi ya alkalization.M`pofunika pulverize mapadi zopangira ndi makina mphamvu kuti kuchepetsa crystallinity ndi polymerization digiri, kuonjezera pamwamba m`dera, ndiyeno kusintha trihydroxyl digiri ndi mankhwala anachita luso la reactant pa shuga mphete ya mapadi polima.

Ngakhale kaphatikizidwe ka hydroxypropyl methylcellulose sikovuta, alkali, zopangira zimapunthwa ndikusinthidwa kukhala alkali.Etherification, zosungunulira zosungunulira, kulekanitsa centrifugal, kutsuka ndi kuyanika m'madera osiyanasiyana, koma kumaphatikizapo matekinoloje ambiri ofunikira komanso chidziwitso chochuluka.Kwa mitundu yosiyanasiyana yazinthu, chilengedwe chilichonse chimakhala ndi zinthu zatsopano zowongolera, monga kutentha, nthawi, kuthamanga ndi kuwongolera kwamayendedwe othandizira ndi zida zowongolera ndi chitsimikizo cha mtundu wokhazikika wazinthu, njira yodalirika yopangira, komanso yabwino.

Popeza ntchito ya hydroxypropyl methylcellulose ndi yofanana ndi ma ether ena osungunuka m'madzi, imatha kugwiritsidwa ntchito ngati chopangira filimu, thickener, emulsifier ndi stabilizer mu utoto wa latex ndi nyimbo zosungunulira za utomoni wamadzi, kukana abrasion, kupaka Uniform ndi kumamatira, komanso kukhazikika kwapamtunda, kukhazikika kwa ma acid ndi maziko, komanso kugwirizana ndi utoto wazitsulo.Hydroxypropyl methylcellulose imakhala ndi zotsatira zabwino ngati zokhuthala za utoto woyera wa polyvinyl acetate.Mlingo wa m'malo mwa cellulose ether ndi bwino, ndipo kukana mabakiteriya kumakhalanso bwino.
