Carboxymethylcellulose (CMC), inozivikanwawo secellulose gum, i polymer inoshanda zvakasiyana-siyana ine huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana siyana.Mushonga uyu, unobva ku cellulose, unoratidza zvimiro zvakasarudzika zvinoita kuti ive yakakosha muminda yakaita sechikafu, mishonga, zvizorwa, machira, nezvimwe zvakawanda.
Mamiriro neZvinhu
Cellulose, iyo yakanyanya kuwanda organic polymer paPasi, inoshanda seyakanyanya kuumbwa chikamu mumasero madziro ezvirimwa.Iri mutsara wepolysaccharide inoumbwa nekudzokorora mayuniti eglucose akabatanidzwa pamwechete ne β(1→4) glycosidic bonds.Carboxymethylcellulose inobva kune cellulose inowanikwa kuburikidza nemakemikari ekugadzirisa maitiro.
Iyo yakakosha shanduko inosanganisira kuunza carboxymethyl mapoka (-CH2-COOH) pamapoka ehydroxyl emusana we cellulose.Kuita uku, kunowanzoitwa kuburikidza ne etherification kana esterification maitiro, inopa kunyungudika kwemvura uye zvimwe zvinhu zvinodikanwa kune cellulose molecule.
Iyo dhigirii yekutsiva (DS) inoreva avhareji nhamba yemapoka ecarboxymethyl akabatanidzwa kune yega yega anhydroglucose unit mucheni ye cellulose.Iyo inonyanya kukanganisa kunyungudika, viscosity, uye mamwe maitiro eCMC.Yepamusoro DS tsika dzinotungamira mukunyungudika kukuru uye zvigadziriso zvakakora.
Carboxymethylcellulose inowanzo kuwanikwa mumagiredhi akasiyana, imwe neimwe yakarongedzerwa kusangana nezvinodiwa zvekushandisa.Aya mamakisi anosiyana mumaparamendi akadai se viscosity, dhigirii rekutsiva, saizi yechidimbu, uye kuchena.
Chimwe chezvinhu zvinonyanya kuzivikanwa zveCMC kugona kwayo kuumba viscous mhinduro mumvura.Kunyangwe pakudzika kwakadzika, inogona kugadzira kukora mhedzisiro nekuda kweiyo polymer chain entanglement uye kusangana nemamorekuru emvura.Izvi zvinoita kuti ive yakanakisa thickening mumiririri mune akawanda maapplication.
Uyezve, carboxymethylcellulose inoratidza yakanakisa firimu-kuumba zvimiro, zvichiita kuti zvive zvakakosha pakugadzira machira nemafirimu ane madhigirii akasiyana ekugonesa uye simba remuchina.Aya mafirimu anowana mashandisirwo mumaindasitiri kubva pakurongedza chikafu kusvika kune ekugadzira mishonga.
Applications
Iko kushandiswa kwakasiyana-siyana kwecarboxymethylcellulose kunobva mukusanganiswa kwayo kwakasiyana kwezvinhu, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa.Zvimwe zvekushandisa zvakakosha zveCMC zvinosanganisira:
Indasitiri yeChikafu: Muindasitiri yechikafu, carboxymethylcellulose inoshanda seyakagadzika, thickener, uye emulsifier muhuwandu hwakawanda hwezvigadzirwa.Inowanzo shandiswa muzvigadzirwa zvemukaka, sosi, mapfekero, zvinhu zvakabikwa, uye zvinwiwa kuvandudza magadzirirwo, muromo, uye kugadzikana pasherufu.Pamusoro pezvo, CMC inoshandiswa mukugadzira gluten-isina kutevedzera magadzirirwo egluten mune zvakabikwa.
Pharmaceuticals: CMC inowana kushandiswa kwakakura mukugadzirwa kwemishonga nekuda kwekugona kwayo kusimudzira viscosity uye kuwirirana kwekumiswa, emulsions, uye mafuta ekuzora.Inoshanda sebhainda mukugadzirwa kwehwendefa, viscosity modifier mune zvinwiwa zvemukanwa, uye inosimbisa mune topical creams uye lotions.Uyezve, carboxymethylcellulose inoshandiswa sechinhu chinoputira mahwendefa, ichigonesa kudzora kuburitswa kwezvinodhaka uye kunatsiridza kumedza.
Cosmetics uye Personal Care: Muzvizoro uye zvigadzirwa zvekuchengeta munhu, CMC inoita seyakakora, inosimbisa, uye inonyorovesa mumiriri.Inosanganiswa mukugadzirwa kwakadai semafuta, lotions, shampoos, uye mushonga wemazino kuti uwedzere kuumbwa, kuwedzera viscosity, uye kupa yakatsetseka, yunifomu kuenderana.
Micheka: Muindasitiri yemachira, carboxymethylcellulose inoshandiswa senge saizi mumiriri kuvandudza maitiro ekuruka uye kupa kuomarara kumachira.Inoshandiswawo seyakakora mumachira ekudhinda machira kuti ive nechokwadi chekufanana uye kupinza kwemadhizaini akadhindwa.
Mafuta neGasi: CMC inoshandiswa muindasitiri yemafuta negasi seviscosifier mukuchera madhaka.Inobatsira kudzora kurasikirwa kwemvura, kunatsiridza kuchenesa gomba, uye kudzikamisa zvibhorani panguva yekuchera.Pamusoro pezvo, carboxymethylcellulose inowana kushandiswa mune hydraulic fracturing zvinwiwa kumisa zvinosimudzira uye kutakura zvinowedzera mukugadzira.
Pepa uye Packaging: Muindasitiri yemapepa, CMC inoshanda sechinhu chinonamira kuvandudza nzvimbo dzebepa, kuwedzera kudhinda, uye kuwedzera kuramba hunyoro.Inoshandiswawo senge saizi mumiriri kuvandudza simba remapepa uye kuderedza kunyura kwemvura.Uyezve, carboxymethylcellulose inoshandiswa mukurongedza zvinhu kupa hunyoro kuramba uye kunatsiridza kunamatira mumalaminates.
Kuvaka: Carboxymethylcellulose inoshandiswa mukuvaka zvinhu zvakaita sedhaka, grouts, uye plaster kuvandudza kushanda, kunamatira, uye kuchengetedza mvura.Iyo inoshanda seyakakora uye rheology modifier, ichiva nechokwadi chekushandisa kwakaringana uye kuita kwezvinhu izvi.
Zvimwe Zvishandiso: Kupfuura maindasitiri ambotaurwa, CMC inowana kushandiswa kwakasiyana siyana senge dhizaini, zvinonamira, ceramics, uye kugadzirisa mvura.Hurukuro hwayo uye kuenderana nezvimwe zvinhu zvinoita kuti ive yekuwedzera yakakosha mune zvisingaverengeki magadzirirwo uye maitiro.
Kukosha uye Benefits
Iko kushandiswa kwakapararira kwecarboxymethylcellulose kunogona kuverengerwa kune akawanda mabhenefiti uye zvakanakira:
Versatility: Kugona kweCMC kushandira akawanda mabasa, anosanganisira kukora, kudzikamisa, kusunga, uye kugadzira firimu, kunoita kuti ive yakawanda kwazvo mumaindasitiri akasiyana siyana.
Chengetedzo: Carboxymethylcellulose inowanzo zivikanwa seyakachengeteka (GRAS) kuti ishandiswe nevane masimba akadai seUS Food and Drug Administration (FDA).Inoisa njodzi shoma kuhutano hwevanhu uye ine nhoroondo refu yekushandiswa zvakachengeteka mukudya, mishonga, uye zvigadzirwa zvekuchengeta munhu.
Eco-Hushamwari: Sechinobva kune cellulose, CMC inotorwa kubva kune inovandudzwa chirimwa masosi, ichiita kuti ive yakasimba nharaunda.Iyo ine biodegradable uye haibatsiri mukusvibisa kwezvakatipoteredza.
Mutengo-Kubudirira: Carboxymethylcellulose inopa inodhura-inoshanda mhinduro yekusimudzira zvimiro zvezvakasiyana zvigadzirwa uye magadzirirwo.Mutengo waro wakaderera kana uchienzaniswa nemamwe ekuwedzera anoita kuti ive sarudzo yakasarudzika kune vakawanda vanogadzira.
Kuita: Iwo akasarudzika zvimiro zveCMC, sekugona kwayo kuumba yakagadzika kumiswa, gobvu gels, uye akasimba mafirimu, anobatsira mukuvandudza mashandiro uye mhando yezvigadzirwa zvekupedzisira.
Regulatory Compliance: Carboxymethylcellulose inoenderana nemirairo uye zvinodiwa mumaindasitiri akasiyana, kuve nechokwadi chekuchengetedzwa kwechigadzirwa uye mhando.
carboxymethylcellulose (CMC) inoita basa rakakosha mumaindasitiri mazhinji sepolymer inogoneka ine akasiyana maapplication.Kubva pachikafu nemishonga kusvika kumachira nekuvaka, CMC inopa yakasarudzika zvivakwa zvinosimudzira mashandiro, mhando, uye kushanda kweakasiyana ezvigadzirwa uye magadzirirwo.Kuchengetedzeka kwayo, kuenderera mberi, uye kudhura-kushanda kunowedzera kukosha kwayo mumagadzirirwo emazuva ano ekugadzira.Sezvo kutsvagisa uye hutsva huchienderera mberi nekuwedzera kunzwisisa kwezvinobuda mu cellulose, mashandisirwo uye kukosha kwecarboxymethylcellulose zvinotarisirwa kukura zvakanyanya mumakore anotevera.
