Xa kuziwa ekunyibilikeni kwe-methyl cellulose, ibhekisa ikakhulu ekunyibilikeni kwe-sodium carboxymethyl cellulose.
I-sodium carboxymethyl cellulose ngumgubo wefiber omhlophe okanye otyheli, ongenavumba kwaye ongenancasa.I-soluble ngokulula emanzini abandayo okanye ashushu, okwenza isisombululo esicacileyo kunye ne-viscosity ethile.
Yintoni ukunyibilika?Enyanisweni, ibhekisa kubunzima be-solute enyibilikisiweyo yinto ethile eqinileyo kwimeko ehluthileyo ngokwe-100g yesinyibilikisi kubushushu obuthile.Oku kukunyibilika.I-solubility ye-methyl cellulose inxulumene nemiba emibini.Ngakolunye uhlangothi, kuxhomekeke kwiimpawu ze-carboxymethyl cellulose, kwaye kwelinye icala, inobudlelwane obuncinane kunye nobushushu bangaphandle, ukufuma, uxinzelelo, uhlobo lwe-solvent, njl njl. iqondo lobushushu, kwaye liya kwanda ngokunyuka kwamaqondo obushushu.
Kukho iindlela ezintathu zokunyibilikisa i-methylcellulose:
1. Indlela yokumanzisa isinyibilikisi se-organic.Le ndlela ikakhulu ukusasaza okanye ezimanzi MC izinyibilikisi eziphilayo ezifana ethanol kunye ethylene glycol kwangaphambili, uze wongeze amanzi ukunyibilika.
2. Indlela yamanzi ashushu.Ngenxa yokuba i-MC ayinyibiliki emanzini ashushu, i-MC inokusasazwa ngokulinganayo kumanzi ashushu kwinqanaba lokuqala.Xa upholisa, ezi ndlela zimbini zilandelayo zinokulandelwa:
(1) Unokuqala ugalele umlinganiselo ofanelekileyo wamanzi ashushu kwisikhongozelo uze usifudumeze ukuya kutsho kuma-70°C.I-MC yongezwa ngokuthe ngcembe ngokushukumisa kancinci, ngokuthe ngcembe yenze i-slurry, eyathi ke yapholiswa ngokushukumisa.
(2) Yongeza i-1/3 yomthamo ofunekayo wamanzi kwisikhongozelo esisisigxina, uyitshise ukuya kuma-70°C, kwaye usasaze i-MC ngokwendlela ekhankanywe apha, uze ulungise uludaka lwamanzi ashushu;uze uyifake emanzini abandayo Yiya kwi-slurry, ugxobhoze kakuhle kwaye upholise umxube.
3. Indlela yokuxuba umgubo.Le ndlela ikakhulu ukusasaza amasuntswana umgubo MC kunye izithako umgubo elinganayo ngokuxubana owomileyo, uze wongeze amanzi ukunyibilika.
