Histori ea Tlhahiso le Lipatlisiso tsa Cellulose Ethers

Li-cellulose ethers li na le nalane e telele ea tlhahiso le lipatlisiso, ho tloha bofelong ba lekholo la bo19 la lilemo. Ether ea pele ea cellulose, ethyl cellulose, e entsoe ka bo-1860 ke setsebi sa k'hemistri sa Borithane Alexander Parkes. Mathoasong a lilemo tsa bo-1900, ether e 'ngoe ea cellulose, methyl cellulose, e ile ea hlahisoa ke setsebi sa k'hemistri sa Lejeremane Arthur Eichengrün.

Lekholong la bo20 la lilemo, tlhahiso le lipatlisiso tsa cellulose ethers li ile tsa eketseha haholo. Lilemong tsa bo-1920, carboxymethyl cellulose (CMC) e ile ea ntlafatsoa e le ether ea cellulose e qhibilihang ka metsing. Sena se ile sa lateloa ke nts'etsopele ea hydroxyethyl cellulose (HEC) lilemong tsa bo-1930, le hydroxypropyl methyl cellulose (HPMC) lilemong tsa bo-1950. Li-cellulose ethers tsena li sebelisoa haholo kajeno liindastering tse fapaneng, ho kenyelletsa lijo, meriana, litlolo le kaho.

Indastering ea lijo, li-cellulose ethers li sebelisoa e le li-thickeners, emulsifiers le li-stabilizers. Hangata li sebelisoa lihlahisoa tse kang liaparo tsa salate, ice cream le lintho tse apehoang. Ka indasteri ea meriana, li-cellulose ethers li sebelisoa e le li-binders, disintegrants, le li-coating agents ka matlapa le li-capsules. Ka indasteri ea litlolo, li sebelisoa e le li-ajenti tse teteaneng le li-emulsifiers ka litlolo le litlolo. Indastering ea kaho, li-cellulose ethers li sebelisoa e le lisebelisoa tsa ho boloka metsi le lisebelisoa tsa ho sebetsa ka samente le seretse.

Patlisiso ka li-cellulose ethers e ntse e tsoela pele ho fihlela kajeno, ho tsepamisitsoe maikutlo ho nts'etsopele ea li-cellulose ether tse ncha le tse ntlafalitsoeng tse nang le thepa le ts'ebetso e ntlafalitsoeng. Tsoelo-pele ea theknoloji e lebisitse ho nts'etsopele ea mekhoa e mecha ea ho hlahisa li-cellulose ethers, tse kang ho fetola li-enzymatic le ho fetola lik'hemik'hale ho sebelisa metsoako e tala. Patlisiso e tsoelang pele le nts'etsopele ea li-cellulose ethers li lebelletsoe ho lebisa lits'ebetsong tse ncha le mebaraka ea lisebelisoa tsena tse fapaneng lilemong tse tlang.
