Inkqubo yemveliso ye-Sodium Carboxymethylcelcelcelcelcelcelose

Inkqubo yokwenziwa kwe-Sodium Carboxymethylcelcelcelcelcelcelcealcelose (CMC) ibandakanya amanyathelo aliqela, kubandakanya ukulungiswa kwe-seluplose, i-etheriya, kunye nokucocwa, kunye nokomisa. Nantsi isishwankathelo senkqubo yokwenziwa kwemveliso yemveliso:

1. Ukulungiswa kwe-seluplose: Inkqubo iqala ngokulungiselela i-selulose, etyalwe kwi-Pulp Pulp okanye i-Cotton News. I-selsulose ihlanjululwe kuqala kwaye ihlaziywe ukususa ukungcola ezinje nge-lignin, i-hemicellulose nakwezinye izinto ezingcolileyo. Le selsulose ehlanjululwe isebenza njengento yokuqalisa ukuvelisa i-CMC.
2. I-Alkalization: Iselsose ehlanjululwe ihlanjululwe ngesisombululo se-alkaline, ihlala iSodium hydroxide (i-nah), ukonyusa i-AURORD yokusabela kwakhona. I-alkali ikwanceda ekudumbe kwaye ivule iintsinga zeselselose, zibenza bafikeleleke kufikeleleko lweekhemikhali.
3. Ukuphendula kwe-Etheriyation Le ndlela yokuphendula ikhokelela ekufakweni kwamaqela e-hydroxyl kwiitayile zeselfowuni kunye ne-carboxymethyl (-C2coona) amaqela. Inqanaba lokufakwa endaweni
4. Ukungathathi cala: Emva kokuphendula kwe-ethersical, imveliso yesiphumo ayithathi cala ukuguqula nawaphi na amaqela ashiyekileyo kwifom yetyuwa yesodium yesodium (i-carboxymethylcelose yesodium. Oku kufezekiswa ngokudibanisa isisombululo se-alkaline, njengeSodium hydroxide (NaYoh), kumxube wokuphendula. Ukungathathi cala kukwanceda ukuhlengahlengisa i-PH yesisombululo kwaye uzinze imveliso ye-CMC.
5. Ukucocwa: I-Creude Sodium Carboxymethylcelcelcelcelose ihlanjululwe ukuze isuse izinto ezingcolileyo, kunye neemveliso ezingekho ngqiqweni, kunye neemveliso ezivela kumxube wokuphendula. Iindlela zokuhlanjululwa zinokubandakanya ukuhlamba, ukuqulunqa, i-ntirifugation, kunye nokomisa. I-CMC ehlanjululwe ihlanjwa ngamanzi ukuze isuse i-Alkali kunye neeSalts, ilandelwe ngokutsalwa kwemveliso ye-CMC evela kwisigaba se-CMC esiqinileyo esivela kwisigaba se-CMC esiqinileyo esivela kwisigaba solwelo esiqinileyo.
6. Ukomisa: I-Sodium ephumeleleyo ye-Sodium ye-Sodiumdymethylcelcelcelose ekugqibeleni yomisiwe isusa umswakama ogqithisileyo kwaye ifumane ukuqhubekeka kokuqhubekeka. Iindlela ezomisa zinokubandakanya ukomisa umoya, ukomisa, okanye idrum yomile, kuxhomekeka kwiimpawu zemveliso oyifunayo kunye nemveliso yemveliso.

I-Sodium ye-sodium ye-sodium ye-coboxymethylcelcelcelcel yemveliso i-white-whider yomgubo okanye umxholo wegranular kunye nomhlaba ogqwesileyo kunye neepropathi zengqolowa. Isetyenziswa ngokubanzi njengearhente yokuthambisa, i-stabilizer, i-binder, kunye ne-geology modifier kwimizi-mveliso eyahlukeneyo, kubandakanya nokutya, amayeza, izicelo, kunye nezicelo zemveliso.
