Yini abaphethe izitha ze-cellulose futhi kungani besetshenziswa?

I-Cellulose Tashers ngama-polymers ancibilikayo ane-cellulose, ingxenye enkulu yesakhiwo sezitshalo. Kunezinhlobo eziningana ze-cellulose iziphathamandla, ngayinye enezakhiwo ezihlukile ezizenza zilungele izinhlelo ezahlukahlukene.

Amamaki obuchwepheshe we-cellulose afers asetshenziswa kukho konke kusuka kuma-Pharmaceuticals kanye nezimonyo zokukhiqiza izindwangu. Ngaphezu kwalokho, zisetshenziswa njengezengezo zokudla kanye nezikhudlwana ngopende kanye nokumboza.

Izinhlobo ze-cellulose afers

Lezi zinhlobo ezintathu ezivame kakhulu ze-cellulose iTefers yi-hydroxypropylmetylcelcellellellellellellellellellose (HPMC), Methylhydroxyethyelcellellulose (Mhec).

Ngenxa yokuguquguquka kwayo, i-HPMC uhlobo olusetshenziswa kakhulu lwe-cellulose ether. Itholakala emabangeni ahlukahlukene ngezinsimbi ezahlukahlukene zamangqamuzana, ama-degrees wokufaka esikhundleni kanye ne-viscosities. I-HPMC ingasetjenziswa kuzo zombili izixazululo ze-acidic ne-alkali, okwenza kube kuhle ngezicelo ezahlukahlukene.

I-MHEC iyafana ne-HPMC kepha inokuqukethwe okuphansi kwe-hydroxypropyl. Uma kuqhathaniswa ne-HPMC, izinga lokushisa le-gelation ye-MHEC livame ukuphakeme kune-80 ° C, ngokuya ngokuqukethwe kweqembu kanye nendlela yokukhiqiza. I-MHEC isetshenziswa kakhulu njengomuntu omkhulu, i-Binder Stabilizer noma ifilimu yangaphambili.

I-Cellulose Tather isebenzisa okuningi ngenxa yezakhiwo zazo ezihlukile. Okunye ukusetshenziswa okuvamile kwe-cellulose afers kufaka:

Ama-Fireners: Izimpi ze-Cellulose zingasetshenziswa njengabakhulu bezithako, izinamathiseli, amakhemikhali e-oilfield, ukudla, izimonyo, kanye nemithi.

Ama-Binders: Abathengisi beCellulose bangasetshenziswa njengezixhumanisi ezibhebheni noma ama-granule. Bathuthukisa ukucindezelwa kwama-powders ngenkathi besagcina izakhiwo ezinhle zokugeleza.

Ama-Emulsion Stailivilizer: Ama-Cellulose Ather angazinza ama-emulsong ngokuvimbela ama-coalescence noma ukugcwala kwamaconsi esigaba ahlakazekile. Lokhu kubenza balungele ukusetshenziswa kuma-emulsion polymers afana nopende we-latex noma anamathela.

Ama-Film Fomu: Izimpikiswano zeCellulose zingasetshenziselwa ukwakha amafilimu noma izimbobo ezisendaweni. Zivame ukusetshenziswa kwizicelo zokwakha ezinjenge-tile noma izinamathiseli sangemuva. Amafilimu asungulwa kusuka kubapholisi we-cellulose avame ukuvela obala futhi avumelana nezimo, ngokumelana kahle nomswakama.
