Carboxymethylcellulose (CMC) nemethylcellulose (MC) zvese zvinobva mu cellulose, iyo polymer yechisikigo inowanikwa mumadziro emasero emiti. Izvi zvinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwehunhu hwazvo hwakasiyana. Pasinei nekufanana kwazvinoita, CMC neMC dzine musiyano wakasiyana mumaumbirwo adzo emakemikari, hunhu, mashandisirwo, uye mashandisirwo emaindasitiri.
1.Maumbirwo emakemikari:
Carboxymethylcellulose (CMC):
CMC inogadzirwa nekushandiswa kwe ether kwe cellulose ne chloroacetic acid, zvichikonzera kuti mapoka e hydroxyl (-OH) atsiviwe pamusana we cellulose nemapoka e carboxymethyl (-CH2COOH).
Dhigirii rekutsiva (DS) muCMC rinoreva huwandu hweavhareji yemapoka ecarboxymethyl payuniti yega yega yeglucose mucheni yecellulose. Iyi parameter inosarudza hunhu hweCMC, kusanganisira kunyungudika, viscosity, uye maitiro erheological.
Methylcellulose (MC):
MC inogadzirwa nekutsiviwa kwemapoka ehydroxyl mu cellulose nemapoka emethyl (-CH3) kuburikidza ne etherification.
Kufanana neCMC, hunhu hweMC hunokanganiswa nehuwandu hwekutsiva, izvo zvinosarudza huwandu hwemethylation iri mucheni ye cellulose.
2. Kunyungudika:
Carboxymethylcellulose (CMC):
CMC inonyungudika mumvura uye inoumba mhinduro dzakajeka, dzakasimba.
Kunyungudika kwayo kunoenderana ne pH, uye kunyungudika kwayo kwakanyanya mumamiriro e alkaline.
Methylcellulose (MC):
MC inonyungudikawo mumvura, asi kunyungudika kwayo kunoenderana nekupisa.
Kana yanyungudutswa mumvura inotonhora, MC inogadzira gel, iyo inonyunguduka inodzokera shure kana yadziiswa. Izvi zvinoita kuti ive yakakodzera kushandiswa inoda gel yakadzorwa.
3. Kupenya:
CMC:
Inoratidza kusimba kwakanyanya mumvura, zvichibatsira kuti iwedzere kukora.
Viscosity yayo inogona kuchinjwa nekugadzirisa zvinhu zvakaita sekuwanda, mwero wekutsiva, uye pH.
MC:
Inoratidza maitiro ekupenya akafanana neCMC asi kazhinji haina kupenya zvakanyanya.
Kupenya kweMC solutions kunogonawo kudzorwa nekuchinja ma parameter akadai setembiricha uye kuwanda.
4. Kuumbwa kwemafirimu:
CMC:
Inoumba mafirimu akajeka, anochinjika kana yagadzirwa kubva mumvura.
Mafirimu aya anoshandiswa mumaindasitiri akadai sekurongedza chikafu uye mishonga.
MC:
Inokwanisawo kugadzira mafirimu asi inowanzova isina kusimba kana tichienzanisa nemafirimu eCMC.
5. Indasitiri yezvekudya:
CMC:
Inoshandiswa zvakanyanya semushonga unosimbisa, unosimbisa, uye unosanganisa chikafu muzvigadzirwa zvekudya zvakaita se ice cream, sauces, uye dressings.
Kukwanisa kwayo kugadzirisa magadzirirwo uye manzwiro emuromo wezvekudya kunoita kuti ive yakakosha muzvikafu.
MC:
Inoshandiswawo seCMC muzvigadzirwa zvekudya, kunyanya mukushandiswa kunoda kugadzirwa kwegel uye kugadzikana.
6. Mishonga:
CMC:
Inoshandiswa mukugadzira mishonga senzira yekubatanidza, kubvisa, uye kugadzirisa viscosity mukugadzira mapiritsi.
Inoshandiswawo mumishonga yekurapa yakadai semakirimu nemajeli nekuda kwehunhu hwayo hwe rheological.
MC:
Inowanzoshandiswa semushonga wekukora uye wekugadzira gelling mumishonga, kunyanya mumishonga inonwiwa nemvura uye mishonga yemaziso.
7. Zvigadzirwa zveKuchengetedza Munhu:
CMC:
Inowanikwa muzvinhu zvakasiyana-siyana zvekuchengetedza muviri zvakaita semazino emazino, shampoo, uye mafuta ekuchenesa mazino senzira yekusimbisa muviri uye kuomesa.
MC:
Inoshandiswawo mukushandiswa kwakafanana neCMC, ichibatsira mukuumbwa uye kugadzikana kwemishonga yekutarisira munhu.
8. Mashandisirwo eIndasitiri:
CMC:
Inoshanda mumaindasitiri akadai semachira, mapepa, uye zviumbwa zvesimbi nekuda kwekugona kwayo kushanda semubati, mugadziri werheology, uye muchengeti wemvura.
MC:
Inoshandiswa muzvinhu zvekuvaka, pendi, uye zvinonamira nekuda kwekukora kwayo uye kubatana kwayo.
nepo carboxymethylcellulose (CMC) nemethylcellulose (MC) zviri zviviri zvinogadzirwa ne cellulose zvine mashandisirwo akasiyana-siyana mumaindasitiri, zvinoratidza musiyano mumaumbirwo azvo emakemikoro, maitiro ekunyungudika, ma profiles ekupenya, uye mashandisirwo. Kunzwisisa musiyano uyu kwakakosha pakusarudza zvinogadzirwa zvakakodzera zvekushandiswa kwakasiyana mumaindasitiri akasiyana-siyana, kubva pakudya nemishonga kusvika pakuchengetedza munhu uye mashandisirwo emaindasitiri. Ingave kudiwa kwechinhu chinosimbisa pH senge CMC muzvigadzirwa zvekudya kana chinhu chinogadzirisa tembiricha senge MC mumafomu emishonga, chimwe nechimwe chinogadzirwa chinopa mabhenefiti akasiyana akagadzirirwa zvinodiwa zvakasiyana mumaindasitiri akasiyana.
