1. Nhanganyaya:
Sodium carboxymethyl cellulose (NaCMC) inonyungudika nemvura kubva kune cellulose inoshandiswa zvakanyanya mumaindasitiri akadai sechikafu, mishonga, zvizorwa, uye machira nekuda kwekukora kwayo, kudzikamisa, uye kugadzira mafirimu. Nekudaro, panguva yekushandiswa kweNaCMC-yakavakirwa zvigadzirwa, akati wandei emuviri uye kemikari shanduko inoitika, ichikanganisa kuita kwayo uye kushanda kwayo.
2.Kuchinja Kwemuviri:
Solubility:
NaCMC inoratidza kunyungudika kwakasiyana zvichienderana nezvinhu zvakaita setembiricha, pH, uye kuvapo kwemunyu.
Nekushandiswa kwenguva refu, kunyungudika kweNaCMC kunogona kudzikira nekuda kwezvinhu zvakaita sekudzikisa huremu hwemamorekuru uye kuyambuka-kubatanidza, zvichikanganisa kuparara kwayo kinetics uye kushanda mukuumbwa.
Viscosity:
Viscosity ndiyo yakakosha paramende inotonga rheological maitiro uye kuita kweNaCMC mhinduro.
Munguva yekushandiswa, zvinhu zvakaita seshear rate, tembiricha, uye kuchembera zvinogona kushandura viscosity yeNaCMC mhinduro, zvichikanganisa kukora kwayo uye kudzikamisa zvivakwa mumashandisirwo akadai sechikafu uye maumbirwo emishonga.
Molecular Weight:
NaCMC inogona kuderedzwa panguva yekushandiswa, zvichikonzera kudzikiswa kwehuremu hwemamorekuru.
Uku kudzikira kwehuremu hwemamorekuru kunogona kukanganisa zvivakwa zvakasiyana, zvinosanganisira viscosity, solubility, uye kugona kugadzira firimu, nekudaro zvichikanganisa kuita kwese kweNaCMC-based zvigadzirwa.
3.Chemical Changes:
Cross-linking:
Muchinjikwa-kubatanidza weNaCMC mamorekuru anogona kuitika panguva yekushandiswa, kunyanya mumashandisirwo anosanganisira kuratidzwa kune divalent cations kana muchinjika-inobatanidza vamiririri.
Cross-linking inoshandura iyo polymer network chimiro, inokanganisa zvivakwa zvakaita solubility, viscosity, uye gelation maitiro, nekudaro zvichipesvedzera kushanda kweNaCMC mumashandisirwo akasiyana.
Magadzirirwo eChimiro:
Kugadziriswa kwemakemikari, senge carboxymethylation degree uye substitution pattern, inogona kuchinja panguva yekushandiswa, ichikanganisa chimiro uye zvimiro zveNaCMC.
Magadzirirwo ezvimiro anopesvedzera zvivakwa zvakaita sekuchengetedza mvura, kusunga simba, uye kunamatira, nekudaro zvichikanganisa mashandiro eNaCMC mumashandisirwo akadai sekuwedzera kwechikafu uye maumbirwo emishonga.
4. Zvinoitika paMaapplication:
Indasitiri yeChikafu:
Shanduko mune zvemuviri uye zvemakemikari zvimiro zveNaCMC panguva yekushandiswa zvinogona kukanganisa mashandiro ayo seyakakora, stabilizer, kana emulsifier mune zvakasiyana zvigadzirwa zvekudya.
Kunzwisisa shanduko idzi kwakakosha kuchengetedza kunaka kwechigadzirwa uye kuenderana mukuumbwa kwechikafu.
Indasitiri yemishonga:
NaCMC inoshandiswa zvakanyanya mukugadzirwa kwemishonga kune yayo binder, disintegrant, uye viscosity-inogadzirisa zvivakwa.
Shanduko mune zvemuviri uye zvemakemikari zvimiro zveNaCMC panguva yekushandiswa zvinogona kukanganisa kuita kwayo mumasisitimu ekutumira zvinodhaka, inodzorwa kuburitsa maumbirwo, uye topical application.
5.Textile Indasitiri:
NaCMC inoshandiswa muindasitiri yemachira kuita saizi, kudhinda, uye kupedza maapplication.
Shanduko muzvivakwa zvakaita seviscosity uye huremu hwemamorekuru panguva yekushandiswa inogona kukanganisa kushanda kweNaCMC-based sizing agents kana kudhinda mapepa, zvichida kugadziridzwa mukugadzira uye kugadzirisa maparamendi.
Sodium carboxymethyl cellulose (NaCMC) inosangana nekuchinja kukuru kwemuviri uye kemikari panguva yekushandiswa, ichikurudzira kunyungudika kwayo, viscosity, uremu hwemamorekuru, uye zvimiro. Shanduko idzi dzine mhedzisiro yakakura pakuita uye kushanda kweNaCMC-yakavakirwa zvigadzirwa mumaindasitiri akasiyana siyana, kusanganisira chikafu, mishonga, uye machira. Kunzwisisa shanduko idzi kwakakosha pakugadzirisa kuumbwa, kugadzirisa, uye kushandiswa kweNaCMC, nekudaro kuve nechokwadi chekuita uye kunaka kwezvigadzirwa zvekupedzisira. Kumwe kutsvagurudza kunotenderwa kuongorora nzira dzekudzikisa shanduko dzisingadiwe uye kuwedzera mashandiro eNaCMC mumashandisirwo akasiyana.
