Kufurira kweDS pane carboxymethyl cellulose Hunhu
Iyo Dhigirii reKutsiva (DS) yakakosha paramende inokanganisa zvakanyanya kunaka uye kuita kweCarboxymethyl Cellulose (CMC). DS inoreva huwandu hweavhareji yemapoka ecarboxymethyl anotsiviwa pane yega yega anhydroglucose unit ye cellulose musana. Iko kukosha kweDS kunokanganisa akasiyana siyana eCMC, kusanganisira kunyungudika kwayo, viscosity, kuchengetedza kwemvura, uye rheological maitiro. Heano maitiro eDS anopesvedzera kunaka kweCMC:
1. Solubility:
- Low DS: CMC ine yakaderera DS inoita kunge isinganyanyike mumvura nekuda kwemapoka mashoma ecarboxymethyl anowanikwa kune ionization. Izvi zvinogona kukonzera kunonoka kunyungudika mazinga uye nguva yakareba ye hydration.
- High DS: CMC ine DS yakakwirira inonyungudika mumvura, sezvo kuwedzera kwenhamba yemapoka e-carboxymethyl inowedzera ionization uye dispersibility yemaketani epolymer. Izvi zvinotungamirira kukurumidza kupera uye kuvandudzwa kwe hydration properties.
2. Viscosity:
- Yakaderera DS: CMC ine yakaderera DS inowanzo ratidza yakaderera viscosity pane yakapihwa concentration ichienzaniswa neakakwira DS mamakisi. Iwo mashoma emapoka e-carboxymethyl anokonzera kushomeka kweionic kudyidzana uye kushomeka kwepolymer cheni kushamwaridzana, zvichiita kuti kuderera kweviscosity.
- Yakakwira DS: Yepamusoro DS CMC mamakisi anowanzo kuve nepamusoro viscosity nekuda kwekuwedzera ionization uye yakasimba polymer cheni kudyidzana. Huwandu hukuru hwemapoka ecarboxymethyl inosimudzira yakawedzera kuwedzera hydrogen bonding uye entanglement, zvichikonzera yakakwirira viscosity mhinduro.
3. Kuchengeta Mvura:
- Yakaderera DS: CMC ine yakaderera DS inogona kunge yakadzikisa simba rekuchengetedza mvura zvichienzaniswa nepamusoro DS mamakisi. Iwo mashoma emapoka ecarboxymethyl anodzikamisa huwandu hwenzvimbo dziripo dzekusunga mvura nekunyura, zvichikonzera kuderera kwemvura.
- Yakakwira DS: Yepamusoro DS CMC mamakisi anowanzo kuratidza epamusoro ekuchengetedza mvura zvivakwa nekuda kwenhamba yakawedzera yemapoka ecarboxymethyl anowanikwa kune hydration. Izvi zvinowedzera kugona kwepolymer kutora nekuchengetedza mvura, ichivandudza kuita kwayo seyakakora, binder, kana hunyoro regulator.
4. Rheological Behaviour:
- Low DS: CMC ine yakaderera DS inowanzova neNewtonian kuyerera maitiro, ine viscosity yakazvimirira pashear rate. Izvi zvinoita kuti ive yakakodzera kune zvikumbiro zvinoda yakagadzikana viscosity pamusoro peyakasiyana siyana yeshear mitengo, senge mukugadzira chikafu.
- Yakakwira DS: Yepamusoro DS CMC mamakisi anogona kuratidza yakawanda pseudoplastic kana shear-kutetepa maitiro, uko viscosity inodzikira nekuwedzera shear rate. Ichi chivakwa chinobatsira maapplication anoda nyore kupomba, kupfapfaidza, kana kuparadzira, senge pendi kana zvigadzirwa zvekuchengeta munhu.
5. Kugadzikana uye Kuenderana:
- Yakaderera DS: CMC ine yakaderera DS inogona kuratidza kugadzikana kuri nani uye kuenderana nezvimwe zvinongedzo mukuumbwa nekuda kweiyo yakaderera ionization uye kushomeka kwekudyidzana. Izvi zvinogona kudzivirira kupatsanurwa kwechikamu, kunaya kwemvura, kana dzimwe nyaya dzakagadzikana mumasisitimu akaomarara.
- Yakakwira DS: Yepamusoro DS CMC mamakisi anogona kunge ari nyore kuita gelation kana kupatsanurwa kwechikamu mumiviri mhinduro kana pakupisa kwakanyanya nekuda kwekusimba kwepolymer kudyidzana. Kunyatsogadzira uye kugadzirisa kunodiwa kuti ive nechokwadi chekugadzikana uye kuenderana mumamiriro ezvinhu akadaro.
iyo Degree of Substitution (DS) inonyanya kukanganisa kunaka, kuita, uye kukodzera kweCarboxymethyl Cellulose (CMC) kune akasiyana maapplication. Kunzwisisa hukama pakati peDS neCMC zvivakwa kwakakosha pakusarudza giredhi rakakodzera kuti isangane nezvinodiwa zvekugadzira uye maitiro ekuita.
