Capsule coating: Iyo firimu-inogadzira midziyo ye cellulose ether inoita kuti ive yakakodzera mushonga wekuputira zvinhu, izvo zvinogona kuparadzanisa zvinodhaka kubva kune ekunze nharaunda, kudzivirira oxidation uye hydrolysis yezvinodhaka, uye kuwedzera kugadzikana kwezvinodhaka.
3. Indasitiri yezvokudya
Muindasitiri yezvekudya, cellulose ethers inoshandiswa zvakanyanya sekuwedzera, kunyanya mune zvakabikwa, zvigadzirwa zvemukaka, zvinwiwa uye chikafu chakaomeswa. Mabasa ayo makuru anosanganisira:
Thickener: Cellulose ethers inogona kuwedzera viscosity yezvikafu zvemvura, kunatsiridza kuravira, uye kuita kuti zvigadzirwa zviwedzere kurongeka uye kukora. Anowanzoshandiswa muzvokudya zvakadai sesosi, jellies, uye mafuta.
Stabilizer: Cellulose ethers, se emulsifiers uye stabilizers, inogona kudzivirira zvinobudirira kupatsanurwa kwemafuta nemvura mukudya uye kuve nechokwadi chekuenderana uye kunaka kwezvigadzirwa.
Humectant: Muzvokudya zvakabikwa, cellulose ethers inogona kubatsira mukanyiwa kuchengetedza unyoro, kudzivirira kurasikirwa kwemvura yakawandisa panguva yekubika, uye kuve nechokwadi chekupfava uye kuravira kwechigadzirwa chakapedzwa.
4. Cosmetics industry
Kushandiswa kwema cellulose ethers muindasitiri yezvizoro kunonyanya kuratidzwa muzvigadzirwa zvekuchengetedza ganda, shampoos, kuchenesa kumeso uye zvigadzirwa zvemakeup. Kunyorova kwayo kwakanyanya, kukora, kugadzira firimu uye kudzikamisa zvivakwa zvinoita kuti ive chinhu chakakosha muzvigadzirwa zvekuzora. Semuyenzaniso:
Moisturizer: Cellulose ethers inogona kugadzira firimu rekudzivirira kuvhara munyoro pamusoro peganda uye kubatsira ganda kuti rirambe rakanyorova.
Thickener: Semukobvu, cellulose ether inopa zvigadzirwa zvekuzora kuenderana kwakakodzera, zvichiita kuti zvive nyore kuisa nekunwa, nekuvandudza ruzivo rwemushandisi.
Emulsifier: Cellulose ether inogona kudzikamisa emulsions, kudzivirira mafuta-mvura stratification, uye kuchengetedza kugadzikana kwezvizorwa formula.
5. Indasitiri yekuchera mafuta
Kushandiswa kweselulosi ether mukubvisa oiri kunonyanya kuratidzwa mukugadzirira kwemvura yekuchera uye zvinwiwa zvinoputika. Cellulose ether inogona kushandiswa seyakakora, inoderedza kurasikirwa kwemvura uye stabilizer kuvandudza kushanda kwemvura yekuchera. Semuyenzaniso:
