Sodium Carboxymethyl cellulose Solubility

Sodium carboxymethyl cellulose (CMC) i polymer inonyungudika nemvura inotorwa kubva ku cellulose, yakasikwa polysaccharide inowanikwa muchirimwa sero madziro.Kunyungudika kweCMC mumvura ndechimwe chezvinhu zvayo zvakakosha uye kunokonzerwa nezvinhu zvakasiyana-siyana, kusanganisira dhigirii rekutsiva (DS), uremu hwemamorekuru, pH, tembiricha, uye kusagadzikana.Heino ongororo yekunyungudika kwe sodium carboxymethyl cellulose:

1. Dhigirii reKutsiva (DS):

• Iyo dhigirii yekutsiva inoreva huwandu hweavhareji yemapoka ecarboxymethyl paglucose unit mune cellulose cheni.Yakakwirira DS maitiro anoratidza dhigirii yakakura yekutsiva uye kuwedzera kunyungudika kwemvura.
• CMC ine yakakwira DS kukosha inoita kuve nekunyungudika kwemvura kuri nani nekuda kwehuwandu hwehuwandu hwemapoka ehydrophilic carboxymethyl padivi pe polymer cheni.

2. Molecular Weight:

• Iyo molecular huremu hweCMC inogona kukanganisa kunyungudika kwayo mumvura.Yepamusoro mamorekuru huremu CMC inogona kuratidza inononoka kupera mazinga kana ichienzaniswa neakaderera mamorekuru uremu mamakisi.
• Nekudaro, kana yanyungudutswa, ese akakwira uye akaderera mamorekuru uremu CMC anowanzo gadzira zvigadziriso zvine akafanana viscosity zvivakwa.

3. pH:

• CMC yakagadzikana uye inonyungudika pamusoro pehupamhi pH renji, kazhinji kubva kune acidic kune alkaline mamiriro.
• Nekudaro, yakanyanyisa pH kukosha inogona kukanganisa kunyungudika uye kugadzikana kweCMC mhinduro.Semuenzaniso, acidic mamiriro anogona protonate carboxyl mapoka, kuderedza solubility, nepo alkaline mamiriro anogona kutungamira kune hydrolysis uye kuderedzwa kweCMC.

4. Tembiricha:

• Iyo solubility yeCMC inowanzo wedzera nekupisa.Kupisa kwepamusoro kunofambisa nzira yekunyungudika uye kunokonzeresa nekukurumidza hydration yeCMC zvimedu.
• Nekudaro, mhinduro dzeCMC dzinogona kuve nekudzikira kwekupisa kune tembiricha yakakwira, zvichitungamira mukudzikisira viscosity uye kugadzikana.

5. Kuvhiringika:

• Kubvongodza kana kusanganisa kunowedzera kunyungudika kweCMC mumvura nekuwedzera kusangana pakati pezvimedu zveCMC nemamorekuru emvura, nekudaro kukurumidza kuita hydration.
• Kugwinya kwakaringana kunowanzodikanwa kuti uwane kupera kwakazara kweCMC, kunyanya kune yakakwira mamorekuru uremu mamakisi kana mumhinduro dzakasimba.

6. Kuisa Munyu:

• Kuvapo kwemunyu, kunyanya divalent kana multivalent cations senge calcium ions, inogona kukanganisa kunyungudika uye kugadzikana kweCMC mhinduro.
• Kuwanda kwemunyu kwakawanda kunogona kutungamira mukuumbwa kwezvisingagadzike kana gel, kuderedza kunyungudika uye kushanda kweCMC.

7. Polymer Concentration:

• CMC solubility inogona zvakare kupesvedzerwa nekusangana kwepolymer mune mhinduro.Kukwirira kwepamusoro kweCMC kungangoda nguva refu yekunyungudika kana kuwedzera kushushikana kuti uwane yakakwana hydration.

Muchidimbu, sodium carboxymethyl cellulose (CMC) inoratidza yakanakisa kunyungudika kwemvura pamusoro peakasiyana mamiriro ezvinhu, zvichiita kuti ive yekuwedzera yakawanda mumaindasitiri akasiyana.Kunyungudika kweCMC kunopesvedzerwa nezvinhu zvakaita sedhigirii rekutsiva (DS), huremu hwemamorekuru, pH, tembiricha, kusagadzikana, munyu, uye kusungwa kwepolymer.Kunzwisisa zvinhu izvi kwakakosha pakugadzirisa kuumbwa uye kuita kweCMC-yakavakirwa zvigadzirwa mumashandisirwo akasiyana.
