Carboxymethylcellulose (CMC) le starch ka bobeli ke polysaccharides, empa li na le meaho e fapaneng, thepa le ts'ebeliso.
Sebopeho sa limolek'hule:
1. Carboxymethylcellulose (CMC):
Carboxymethylcellulose e tsoa ho selulose, polymer e nang le mela e entsoeng ka likaroloana tsa tsoekere tse hokahantsoeng ke β-1,4-glycosidic bond.Phetoho ea selulose e kenyelletsa ho hlahisoa ha lihlopha tsa carboxymethyl ka etherification, ho hlahisa carboxymethylcellulose.Sehlopha sa carboxymethyl se etsa hore CMC e qhibilihe ka metsing 'me e fane ka thepa e ikhethang ea polymer.
2. Starch:
Starch ke lik'habohaedreite tse entsoeng ka likaroloana tsa tsoekere tse hokahantsoeng ke α-1,4-glycosidic bond.Ke polymer ea tlhaho e fumanoang limela e sebelisoang e le motsoako oa ho boloka matla.Limolek'hule tsa starch hangata li entsoe ka mefuta e 'meli ea li-polymer tsa tsoekere: amylose (ketane e otlolohileng) le amylopectin (mehaho ea ketane ea makala).
Lintho tsa 'mele:
1. Carboxymethylcellulose (CMC):
Sollubility: CMC e qhibiliha ka metsing ka lebaka la boteng ba lihlopha tsa carboxymethyl.
Viscosity: E bonts'a viscosity e phahameng ka tharollo, e etsa hore e be ea bohlokoa lits'ebetsong tse fapaneng tse kang ho lokisa lijo le meriana.
Ponaletso: Litharollo tsa CMC hangata li pepeneneng.
2. Starch:
Sollubility: Native starch ha e qhibilihe ka metsing.E hloka gelatinization (ho futhumatsa ka metsing) e le hore e qhibilihe.
Viscosity: Setlolo sa starch se na le viscosity, empa hangata se tlase ho feta CMC.
Ho pepeseha: Li-starch pastes li na le ho ba opaque, 'me tekanyo ea opacity e ka fapana ho itšetlehile ka mofuta oa starch.
mohloli:
1. Carboxymethylcellulose (CMC):
CMC hangata e entsoe ka selulose ho tsoa mehloling ea limela joalo ka makhasi a patsi kapa k'hothone.
2. Starch:
Limela tse kang poone, koro, litapole le raese li na le starch e ngata.Ke motsoako oa mantlha lijong tse ngata tsa mantlha.
Mokhoa oa Tlhahiso:
1. Carboxymethylcellulose (CMC):
Tlhahiso ea CMC e kenyelletsa karabelo ea etherification ea selulose ka chloroacetic acid ka har'a alkaline medium.Karabelo ena e fella ka ho nkeloa sebaka ha lihlopha tsa hydroxyl ka selulose ka lihlopha tsa carboxymethyl.
2. Starch:
Ho ntšoa ha starch ho kenyelletsa ho pshatla lisele tsa semela le ho arola li-granules tsa starch.Setache se ntšitsoeng se ka kena lits'ebetsong tse fapaneng, ho kenyelletsa le phetoho le gelatinization, ho fumana thepa e lakatsehang.
Morero le ts'ebeliso:
1. Carboxymethylcellulose (CMC):
Indasteri ea lijo: CMC e sebelisoa e le motenya, stabilizer le emulsifier lijong tse fapaneng.
Meriana ea Meriana: Ka lebaka la thepa ea eona e tlamang le ea ho qhalana, e fumana tšebeliso ea metsoako ea meriana.
Ho Cheka Oli: CMC e sebelisoa marong a ho cheka oli ho laola rheology.
2. Starch:
Indasteri ea lijo: Starch ke karolo e ka sehloohong ea lijo tse ngata 'me e sebelisoa e le ntho e teteaneng, gelling agent le stabilizer.
Indasteri ea masela: Starch e sebelisoa ka boholo ba masela ho fana ka boima ba masela.
Indasteri ea pampiri: Starch e sebelisoa ho etsa pampiri ho eketsa matla a pampiri le ho ntlafatsa thepa ea bokaholimo.
Leha CMC le starch e le li-polysaccharides ka bobeli, li na le phapang lipakeng tsa sebopeho sa limolek'hule, thepa ea 'mele, mehloli, lits'ebetso tsa tlhahiso le lits'ebetso.CMC ha e qhibilihe ka metsing ebile e na le viscous haholo 'me hangata e ratoa lits'ebetsong tse hlokang thepa ena, athe starch ke polysaccharide e feto-fetohang e sebelisoang haholo indastering ea lijo, masela le pampiri.Ho utloisisa liphapang tsena ho bohlokoa ho khetha polymer e nepahetseng bakeng sa lits'ebetso tse ikhethileng tsa indasteri le tsa khoebo.
