Sodium carboxymethylcellulose (CMC) i polymer inoshanda zvakasiyana-siyana uye ine zvakawanda zvekushandisa mumhando dzakasiyana dzemaindasitiri.Mushonga uyu unotorwa kubva ku cellulose, polima yemusikirwo inowanikwa mumadziro esero rezvirimwa.CMC inogadzirwa nemakemikari ekugadzirisa cellulose nekuunza mapoka ecarboxymethyl mumusana we cellulose.Iyo inokonzeresa sodium carboxymethylcellulose ine yakasarudzika zvivakwa zvinoita kuti ive yakakosha mune akawanda maapplication.
Molecular Structure:
Iyo molecular chimiro che sodium carboxymethylcellulose ine cellulose musana ine carboxymethyl mapoka (-CH2-COO-Na) akabatana kune mamwe mapoka ehydroxyl pazvikamu zveglucose.Iyi shanduko inopa kunyungudika uye zvimwe zvinobatsira zvivakwa kune cellulose polymer.
Solubility uye mhinduro zvivakwa:
Chimwe chezvinhu zvikuru zveCMC ndiko kunyungudika kwemvura.Sodium carboxymethyl cellulose inonyungudika zviri nyore mumvura uye inoumba yakajeka viscous mhinduro.Solubility inogona kugadziridzwa nekuchinja dhigirii rekutsiva (DS), inova iyo avhareji nhamba yemapoka ecarboxymethyl pachikamu cheglucose mucheni ye cellulose.
Rheological properties:
Iyo rheological maitiro eCMC mhinduro akakosha.Iyo viscosity yeCMC mhinduro inowedzera nekuwedzera kukoshesa uye zvakanyanya zvinoenderana nehuwandu hwekutsiva.Izvi zvinoita kuti CMC ive yakakora inoshanda mumhando dzakasiyana dzekushandisa, kusanganisira chikafu, mishonga uye maindasitiri maitiro.
Ionic zvinhu:
Kuvapo kwemaion sodium mumapoka ecarboxymethyl kunopa CMC hunhu hwayo.Iyi ionic chimiro inobvumira CMC kudyidzana nedzimwe mhuka dzakachajwa mumhinduro, zvichiita kuti ive yakakosha mumashandisirwo anoda kusunga kana kuumbwa kwegel.
pH sensitivity:
Iyo solubility uye zvivakwa zveCMC zvinokanganiswa nepH.CMC ine yakanyanya solubility uye inoratidza kuita kwayo kwakanyanya pasi pemamiriro ealkaline zvishoma.Nekudaro, inoramba yakagadzikana pamusoro pehupamhi pH renji, ichipa kuchinjika kune akasiyana maapplication.
Mafirimu ekugadzira zvinhu:
Sodium carboxymethylcellulose ine hunyanzvi hwekugadzira firimu, ichiita kuti ive yakakodzera kune maapplication anoda kuumbwa kwemafirimu matete kana machira.Ichi chivakwa chinogona kushandiswa kugadzira mafirimu anodyiwa, machira epatafura, nezvimwe.
Gadzirisa:
CMC yakagadzikana pasi peakasiyana emamiriro ekunze, kusanganisira tembiricha uye pH shanduko.Uku kugadzikana kunobatsira kuhupenyu hwayo hurefu hwesherufu uye kukodzera kune zvakasiyana-siyana zvekushandisa.
Emulsion stabilizer:
CMC inoshanda senge emulsifier inoshanda uye inobatsira kudzikamisa emulsions muchikafu uye zvizorwa magadzirirwo.Iyo inovandudza kugadzikana kwemafuta-mu-mvura emulsions, kubatsira kuvandudza huwandu hwese uye hupenyu hwesherufu hwechigadzirwa.
Kuchengeta mvura:
Nekuda kwekugona kwayo kutora mvura, CMC inoshandiswa sechinhu chekuchengetedza mvura mumaindasitiri akasiyana.Ichi chivakwa chinobatsira zvakanyanya pakushandisa senge machira, uko CMC inobatsira kuchengetedza hunyoro hwemachira panguva dzakasiyana siyana.
Biodegradability:
Sodium carboxymethylcellulose inoonekwa seyakaora nekuti inotorwa kubva kune cellulose, inongoitika polima.Ichi chimiro chine hushamwari hwakatipoteredza uye chiri kuenderana nekukura kuri kudiwa kwezvinhu zvinogoneka mumaindasitiri.
application:
indasitiri yezvekudya:
CMC inoshandiswa zvakanyanya seyakakora, stabilizer uye texturizer muchikafu.
Inosimudzira viscosity uye kuumbwa kwemasosi, mapfekero uye zvigadzirwa zvemukaka.
mushonga:
CMC inoshandiswa sebhainda mukugadzirwa kwemapiritsi emishonga.
Inoshandiswa mukugadzirwa kwepamusoro kupa viscosity uye kuwedzera kugadzikana kwemajeri nemafuta.
textile:
CMC inoshandiswa mukugadzira machira senge saizi ajenti uye gobvu mumiriri wekudhinda mapeji.
Inovandudza dhayi kunamatira kune jira uye inovandudza kudhinda mhando.
Indasitiri yeOiri neGasi:
CMC inoshandiswa mukuchera zvinwiwa kudzora viscosity uye yakaturikwa yakasimba.
Inoshanda senge inoderedza kurasikirwa kwemvura uye inovandudza kugadzikana kwekuchera madhaka.
Indasitiri yemapepa:
CMC inoshandiswa semumiriri wekuputira bepa kuvandudza kusimba uye kudhindwa kwebepa.
Inoshanda sechibatsiro chekuchengetedza mukugadzirisa mapepa.
Zvigadzirwa zvekuchengeta wega:
CMC inowanikwa mune zvakasiyana siyana zvekuchengetedza zvega zvigadzirwa senge mushonga wemazino uye shampoo seyakakora uye inodzikamisa.
Iyo inobatsira kune iyo yakazara magadzirirwo uye kuenderana kwezvizorwa mafomula.
Detergents uye cleaners:
CMC inoshandiswa seyakakora uye inodzikamisa mune yekuchenesa mvura.
Inowedzera viscosity yemhinduro yekuchenesa, inovandudza kushanda kwayo.
Ceramics uye Architecture:
CMC inoshandiswa sebhainda uye rheology modifier mumakeramiki.
Inoshandiswa mukuvaka zvinhu kuvandudza kuchengetedza kwemvura uye zvivakwa zvekuvaka.
Toxicity uye kuchengeteka:
Carboxymethylcellulose inowanzo zivikanwa seyakachengeteka (GRAS) nemasangano anodzora kuti ashandiswe muchikafu nemishonga yekushandisa.Haina chepfu uye inobvumirwa zvakanaka, ichiwedzera kukurudzira kushandiswa kwayo kwakapararira.
mukupedzisa:
Sodium carboxymethyl cellulose i polymer yakawanda ine huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana.Hunhu hwayo hwakasiyana, hunosanganisira kunyungudika kwemvura, rheological maitiro, ionic zvimiro uye kugona kugadzira firimu, inoita kuti ive chinhu chakakosha mukudya, mishonga yemishonga, machira nezvimwe zvakawanda zvigadzirwa.Sezvo maindasitiri achiramba achitsvaga zvinogoneka uye zvinoshanda zvakawanda, sodium carboxymethyl cellulose inogona kuwedzera mukukosha, ichisimbisa chinzvimbo chayo semutambi akakosha mupolymer chemistry uye maindasitiri ekushandisa.
