Uma kukhulunywa ngokuncibilika kwe-methyl cellulose, ibhekisa kakhulu ekuncibilikeni kwe-sodium carboxymethyl cellulose.
I-sodium carboxymethyl cellulose iyimpushana ye-flocculent emhlophe noma ephuzi, engenaphunga futhi ayinambitheki.Incibilika kalula emanzini abandayo noma ashisayo, yakha isixazululo esisobala nge-viscosity ethile.
Kuyini ukuncibilika?Eqinisweni, kubhekiselwa esixukwini se-solute encibilika into ethile eqinile esimweni sokugcwala ngokuqhathaniswa ku-100g we-solvent ezingeni lokushisa elithile.Lokhu ukuncibilika.I-solubility ye-methyl cellulose ihlobene nezici ezimbili.Ngakolunye uhlangothi, kuncike ezicini ze-carboxymethyl cellulose, futhi ngakolunye uhlangothi, inobudlelwane obuncane nezinga lokushisa langaphandle, umswakama, ingcindezi, uhlobo lwe-solvent, njll. I-solubility ye-carboxymethyl cellulose ivame ukuthinteka ngokusobala izinga lokushisa, futhi lizokhula ngokunyuka kwezinga lokushisa.
Kunezindlela ezintathu zokuqeda i-methylcellulose:
1. Indlela yokumanzisa i-solvent ye-organic.Le ndlela ngokuyinhloko iwukuhlakaza noma okumanzi izinyibilikisi ze-MC eziphilayo njenge-ethanol ne-ethylene glycol kusengaphambili, bese wengeza amanzi ukuze ancibilike.
2. Indlela yamanzi ashisayo.Ngenxa yokuthi i-MC ayincibiliki emanzini ashisayo, i-MC ingahlakazwa ngokulinganayo emanzini ashisayo esigabeni sokuqala.Lapho ukupholisa, izindlela ezimbili ezilandelayo zingalandelwa:
(1) Ungaqale wengeze inani elifanele lamanzi ashisayo esitsheni bese usishisa kuze kufike ku-70°C.I-MC yanezelwa kancane kancane ngokunyakazisa kancane, kancane kancane yakha i-slurry, eyabe ipholiswa ngokugqugquzela.
(2) Faka i-1/3 yenani elidingekayo lamanzi esitsheni esingashintshi, sishise sibe ngu-70°C, bese uhlakaza i-MC ngokwendlela esanda kushiwo, bese ulungisa udaka lwamanzi ashisayo;bese uyifaka emanzini abandayo Hamba ku-slurry, ugovuze kahle bese upholisa ingxube.
3. Indlela yokuxuba impushana.Le ndlela ngokuyinhloko iwukuhlakaza izinhlayiya ze-MC powder kanye nezithako zempushana ezilinganayo ngokuxuba okomile, bese wengeza amanzi ukuze ancibilike.
