Nhanganyaya yeCarboxymethyl Cellulose (CMC)
Carboxymethyl cellulose, inowanzopfupikiswa seCMC, inotorwa zvakasiyana-siyana kubva kune cellulose, inongoitika polima inowanikwa mumadziro emiti.Inowanikwa kuburikidza nekugadziriswa kwemakemikari ye cellulose, kunyanya nekuiswa kwemapoka e-carboxymethyl (-CH2-COOH) pamusana we cellulose.
Mamiriro neZvinhu
CMC inochengetedza chimiro che cellulose, inova mutsara wetani yemamorekuru eglucose akabatanidzwa ne β(1 → 4) glycosidic bond.Nekudaro, kuunzwa kwemapoka ecarboxymethyl kunopa akati wandei akakosha zvivakwa kuCMC:
Kunyungudika kweMvura: Kusiyana ne cellulose yemuno, isinganyungudika mumvura, CMC inonyungudika zvakanyanya mumvura inopisa uye inotonhora nekuda kweiyo hydrophilic yemapoka ecarboxymethyl.
Thickening Agent: CMC inoshanda gobvu mumiriri, ichigadzira viscous mhinduro pane yakaderera.Ichi chivakwa chinoita kuti ive yakakosha mumhando dzakasiyana dzekushandisa, kusanganisira chikafu, mishonga, uye zvigadzirwa zvekuchengeta munhu.
Firimu-Kugadzira Kugona: CMC inogona kugadzira mafirimu kana yaiswa kubva mumhinduro, ichiita kuti ishande mumashandisirwo panodiwa firimu rakatetepa, rinochinjika, senge mumajasi uye zvinonamira.
Kugadzikana uye Kuenderana: CMC yakagadzikana pamusoro pehupamhi hwepH uye tembiricha mamiriro, zvichiita kuti ienderane nezvimwe zvakasiyana-siyana zvinongedzo uye yakakodzera kune akasiyana maapplication.
Applications
Izvo zvakasiyana-siyana zvivakwa zveCMC zvinowana application kune akati wandei maindasitiri:
Indasitiri Yezvekudya: CMC inoshandiswa zvakanyanya seyakakora, inodzikamisa, uye emulsifier muzvigadzirwa zvekudya zvakaita sesosi, madhirezi, ice cream, uye zvinhu zvekubheka.Inovandudza kuumbwa, muromo, uye kugadzikana kwesherufu.
Pharmaceuticals: Mukugadzirwa kwemishonga, CMC inoshanda sebhainda, disintegrant, uye inodzorwa-inoburitsa mumiririri mumapiritsi nemakapisi.Kugona kwayo kugadzira gel dzakagadzika zvakare kunoita kuti ive yakakosha mumasikirwo emusoro senge makirimu uye lotions.
Personal Care Zvigadzirwa: CMC chinhu chakajairika muzvigadzirwa zvekuchengeta zvemunhu senge mazino, shampoos, uye makirimu, kwaanoshanda seanokora, anosimbisa, uye anochengetedza hunyoro.
Indasitiri yePepa: Mukugadzira mapepa, CMC inoshandiswa seyepamusoro saizi mumiriri kuvandudza simba rebepa, kutsvedzereka, uye inki kugamuchira.Inoshandawo sechiyamuro chekuchengetedza, ichibatsira kusunga zvimedu zvakanaka uye mafiritsi kune pepa.
Micheka: CMC inoshandiswa mukudhinda machira uye kudhaya maitiro seyakakora uye rheology modifier yekudhinda mapeji uye dhayi yekugezera.
Kuchera Oiri: Muindasitiri yekuchera oiri, CMC inowedzerwa kumvura yekuchera kuti ipe viscosity control, kudzikisira kurasikirwa kwemvura, uye mafuta ekudhira.
Iko kushandiswa kwakapararira kwecarboxymethyl cellulose kunoratidzwa nekubatanidzwa kwayo kwakasarudzika kwezvivakwa, izvo zvinogonesa kushandiswa kwayo munzvimbo dzakasiyana.Iyo biodegradability uye isiri-chepfu inowedzera kukwidza kukwezva kwayo seyakasimba uye ine hushamwari kune imwe nzvimbo kune ekugadzira mapolymer mune akawanda maapplication.
carboxymethyl cellulose ichokwadi cellulose ether ine huwandu hwakasiyana hwekushandisa nekuda kwekunyungudika kwayo kwemvura, kukora zvimiro, kugadzikana, uye kuenderana nezvimwe zvinhu.Kukosha kwayo kunotenderera mumaindasitiri, zvichiita kuti ive chinhu chakakosha muzvigadzirwa zvakawanda uye maitiro.
