Carboxymethylcellulose (CMC) uye cellulose ese ari maviri mapolysaccharides ane akasiyana zvivakwa uye mashandisirwo. Kunzwisisa mutsauko wavo kunoda kuongorora zvimiro zvavo, zvivakwa, mabviro, nzira dzekugadzira, uye mashandisiro.
Cellulose:
1. Tsanangudzo uye chimiro:
Cellulose inonzi polysaccharide yakasikwa inoumbwa nemaketani akaenzana e-β-D-glucose units akabatanidzwa ne β-1,4-glycosidic bonds.
Icho chikamu chikuru chechimiro chemiti yesero madziro, ichipa simba uye kusimba.
2. Kwakabva:
Cellulose yakawanda muzvisikwa uye inonyanya kutorwa kubva kune zvidyarwa zvakadai sehuni, donje uye zvimwe fibrous zvinhu.
3. Kugadzirwa:
Kugadzirwa kwe cellulose kunosanganisira kubvisa cellulose kubva muzvirimwa uye wozoigadzira kuburikidza nenzira dzakadai semakemikari pulping kana mechanic kugaya kuti uwane iyo fiber.
4. Kuita:
Mune chimiro chayo chechisikigo, cellulose haina kunyungudika mumvura uye yakawanda organic solvents.
Iyo ine yakakwira tensile simba, ichiita kuti ive yakakodzera kune maapplication uko kusimba uye kusimba kwakakosha.
Cellulose ine biodegradable uye inochengetedza zvakatipoteredza.
5. Application:
Cellulose ine zvakasiyana-siyana zvekushandisa, zvinosanganisira kugadzirwa kwepepa uye bhodhi, machira, cellulose-based mapurasitiki, uye seyekudya fiber supplement.
Carboxymethylcellulose (CMC):
1. Tsanangudzo uye chimiro:
Carboxymethylcellulose (CMC) inobva kune cellulose umo macarboxymethyl mapoka (-CH2-COOH) anounzwa mumusana we cellulose.
2. Kugadzirwa:
CMC inowanzogadzirwa nekurapa cellulose ne chloroacetic acid uye alkali, zvichikonzera kutsiviwa kwemapoka ehydroxyl mu cellulose nemapoka ecarboxymethyl.
3. Solubility:
Kusiyana ne cellulose, CMC inonyungudika mumvura uye inoumba colloidal mhinduro kana gel zvichienderana nekusungwa.
4. Kuita:
CMC ine zvese zviri zviviri hydrophilic uye hydrophobic zvivakwa, zvichiita kuti ive yakakodzera kune akasiyana maapplication muchikamu chekudya, chemishonga uye maindasitiri.
Iyo ine bhaisikopo-kugadzira masimba uye inogona kushandiswa seyakakora kana kudzikamisa.
5. Application:
CMC inoshandiswa muindasitiri yechikafu seyakakora, inodzikamisa uye emulsifier muzvigadzirwa zvakaita seaizikirimu nemapfekero esaladhi.
Mumishonga yemishonga, CMC inoshandiswa sebhainda mukugadzira mapiritsi.
Inoshandiswa mukuyera uye kupedzisa maitiro eindasitiri yemachira.
musiyano:
1. Solubility:
Cellulose haina kunyungudika mumvura, nepo CMC ichinyungudika mumvura. Uyu mutsauko mukunyungudika unoita kuti CMC iwande kuita zvakasiyana-siyana mukushandisa kwakasiyana-siyana, kunyanya mumaindasitiri uko maumbirwo emvura anodiwa.
2. Maitiro ekugadzira:
Kugadzirwa kwe cellulose kunosanganisira kudhirowa uye kugadzirwa kubva muzvirimwa, nepo CMC inogadzirwa kuburikidza nemakemikari ekugadzirisa maitiro anosanganisira cellulose uye carboxymethylation.
3. Mamiriro:
Cellulose ine mutsara uye isina branch chimiro, nepo CMC ine carboxymethyl mapoka akasungirirwa kune cellulose musana, ichipa yakagadziridzwa chimiro nekunyungudika kunyungudika.
4. Application:
Cellulose inonyanya kushandiswa mumaindasitiri akadai semapepa uye machira uko kusimba kwayo uye kusanyungudika kunopa zvakanakira.
CMC, kune rumwe rutivi, inoshandiswa muhuwandu hwakawanda hwemaindasitiri, kusanganisira chikafu, mishonga yemishonga uye zvizorwa, nekuda kwekunyungudika kwayo kwemvura uye kuita zvakasiyana.
5. Zvimiro zvemuviri:
Cellulose inozivikanwa nokuda kwesimba rayo uye kusimba, zvichiita kuti kuumbwa kwemiti kutendeke.
CMC inogara nhaka yezvimwe zvivakwa zve cellulose asi zvakare ine zvimwe, sekugona kuumba gels uye mhinduro, ichipa iyo yakafararira yekushandiswa.
Kunyangwe cellulose uye carboxymethyl cellulose zvine mavambo akafanana, zvimiro zvavo zvakasiyana uye zvimiro zvakatungamira kune akasiyana mashandisirwo mumaindasitiri akasiyana. Simba reCellulose uye kusanyungudika kunogona kubatsira mune mamwe mamiriro, nepo kunyungudika kwemvura kweCMC uye chimiro chakagadziridzwa chinoita kuti ive chinhu chakakosha mumhando yezvigadzirwa uye magadzirirwo.
