Carboxymethyl cellulose (CMC) ndeye multifunctional polymer material inoshandiswa zvakanyanya mukudya, mishonga, cosmetics, petroleum, papermaking, machira uye mamwe maindasitiri. Zvakanakira zvaro zvinosanganisira kukora, kudzikamisa, kumiswa, emulsification, kuchengetedza mvura uye mamwe mabasa, saka inoshandiswa zvakanyanya muminda yakawanda. Nekudaro, zvisinei nekuita kwayo kwakanaka mukushandisa kwakawanda, CMC inewo zvimwe zvayakaipira uye zvinogumira, izvo zvinogona kudzikisira kushandiswa kwayo mune dzimwe nguva kana kuda matanho chaiwo ekukunda izvi zvisingabatsiri.
1. Kunyungudika kwakaganhurirwa
Kunyungudika kweCMC mumvura chinhu chakakosha hunhu, asi mune mamwe mamiriro, kunyungudika kunogona kuve kushoma. Semuenzaniso, CMC haina kunyungudika kwakashata munzvimbo dzine munyu wakanyanya kana kuoma kwemvura. Munzvimbo ine munyu wakanyanya, iyo electrostatic repulsion pakati peCMC molecular cheni inoderedzwa, zvichikonzera kuwedzera kwekudyidzana kweintermolecular, kunokanganisa kunyungudika kwayo. Izvi zvinonyanya kuoneka pazvinoshandiswa mumvura yegungwa kana mvura ine mamineral akawanda. Pamusoro pezvo, CMC inonyungudika zvishoma nezvishoma mumvura yakadzika-tembiricha uye inogona kutora nguva yakareba kuti inyunguduke, izvo zvinogona kutungamira mukudzikiswa kwekuita mukugadzirwa kwemaindasitiri.
2. Kusagadzikana kweviscosity kugadzikana
Iyo viscosity yeCMC inogona kukanganiswa nepH, tembiricha, uye ionic simba panguva yekushandiswa. Pasi pe acidic kana alkaline mamiriro, viscosity yeCMC inogona kuderera zvakanyanya, ichikanganisa kukora kwayo. Izvi zvinogona kuve nemhedzisiro yakaipa pane mamwe maapplication anoda yakagadzikana viscosity, senge kugadzira chikafu uye kugadzirira mishonga. Pamusoro pezvo, pasi pemamiriro ekushisa kwakanyanya, viscosity yeCMC inogona kudonha nekukurumidza, zvichikonzera kushanda kushoma mune mamwe maapplication ekupisa.
3. Kusakwana kwebiodegradability
CMC ndeye yakagadziridzwa cellulose ine inononoka kudzikira mwero, kunyanya munzvimbo dzakasikwa. Naizvozvo, CMC ine biodegradability yakashata uye inogona kuunza mumwe mutoro kune zvakatipoteredza. Kunyangwe CMC iri nani pa biodegradation pane mamwe mapolymer ekugadzira, maitiro ayo ekusvibisa achiri kutora nguva yakareba. Mune mamwe maapplication anoona nezvezvakatipoteredza, izvi zvinogona kuve chinhu chakakosha kufunga, zvichiita kuti vanhu vatarise zvimwe zvinhu zvine hushamwari zvakatipoteredza.
4. Kemikari kugadzikana nyaya
CMC inogona kunge isina kugadzikana mune mamwe makemikari nharaunda, senge yakasimba asidhi, hwaro hwakasimba kana oxidative mamiriro. Kuora kana kuita kwemakemikari kunogona kuitika. Kusagadzikana uku kunogona kuderedza kushandiswa kwayo mune chaiyo makemikari nharaunda. Munzvimbo ine oxidizing yakanyanya, CMC inogona kusangana neoxidative degradation, nekudaro ichirasikirwa nekushanda kwayo. Mukuwedzera, mune dzimwe mhinduro dzine simbi ions, CMC inogona kubatanidza nesimbi ions, zvichikanganisa kunyungudika kwayo uye kugadzikana.
5. Mutengo wepamusoro
Kunyangwe CMC chiri chinhu chine mashandiro akanaka, mutengo wayo wekugadzira wakakwira, kunyanya zvigadzirwa zveCMC zvine kuchena kwakanyanya kana mamwe mabasa. Naizvozvo, mune mamwe maapplication asingatengi, kushandiswa kweCMC kunogona kunge kusiri kwehupfumi. Izvi zvinogona kuita kuti makambani atarise dzimwe nzira dzinodhura zvakanyanya kana uchisarudza makobvu kana zvinodzikamisa, kunyangwe nzira idzi dzinogona kunge dzisina kunaka seCMC mukuita.
6. Panogona kuva ne-zvigadzirwa mukugadzirwa kwekugadzira
Kugadzirwa kweCMC kunosanganisira kugadziridzwa kwekemikari ye cellulose, iyo inogona kuburitsa zvimwe zvigadzirwa, senge sodium chloride, sodium carboxylic acid, etc. Izvi zvinogadzirwa zvinogona kukanganisa kushanda kweCMC kana kuunza tsvina isingadikanwi mune mamwe mamiriro. Pamusoro pezvo, mareagents emakemikari anoshandiswa mukugadzira anogona kuve nemhedzisiro yakaipa pane zvakatipoteredza kana akasabatwa nemazvo. Naizvozvo, kunyangwe CMC pachayo iine akawanda akanakisa zvivakwa, kwezvakatipoteredza uye hutano kukanganisa kwemaitiro ayo ekugadzira zvakare chinhu chinoda kutariswa.
7. Biocompatibility shoma
Kunyangwe CMC ichishandiswa zvakanyanya mukurapa uye zvekuzora uye ine yakanaka biocompatibility, biocompatibility yayo inogona kunge ichiri isina kukwana mune mamwe maapplication. Semuyenzaniso, mune dzimwe nguva, CMC inogona kukonzera nyoro ganda kushatirwa kana allergic reaction, kunyanya kana ichishandiswa pakanyanya kuwanda kana kwenguva yakareba. Pamusoro pezvo, iyo metabolism uye kubviswa kweCMC mumuviri kunogona kutora nguva yakareba, izvo zvingave zvisina kunaka mune mamwe masystem ekuunza zvinodhaka.
8. Michina isina kukwana zvinhu
Seyakakora uye inodzikamisa, CMC ine yakaderera mechani simba, inogona kunge iri inodzikamisa chinhu mune zvimwe zvinhu zvinoda simba repamusoro kana kukwirira kwepamusoro. Semuyenzaniso, mune mamwe machira kana zvinhu zvakaumbwa zvine simba rakawanda zvinodiwa, kushandiswa kweCMC kunogona kushomeka kana kungangoda kushandiswa pamwe chete nezvimwe zvinhu kusimudzira michina yayo.
Seyakashandiswa zvakanyanya multifunctional material, carboxymethyl cellulose (CMC) ine zvakawanda zvakanakira, asi zvayakaipira uye zvisingakwanisi kuregererwa. Paunenge uchishandisa CMC, zvinhu zvakaita sekunyungudika kwayo, kugadzikana kwe viscosity, kugadzikana kwemakemikari, kukanganisa kwezvakatipoteredza uye mutengo zvinofanirwa kutariswa zvinoenderana nechaiyo application mamiriro. Pamusoro pezvo, kutsvagisa uye kusimudzira kweramangwana kunogona kuwedzera kuvandudza mashandiro eCMC uye kukurira kukanganisa kwairipo, nekudaro ichiwedzera kugona kwayo kwekushandisa mune mamwe minda.
