Incazelo emfushane:

I-Carboxymethylation reaction ingenye yobuchwepheshe be-etherification.Ngemuva kwe-Carboxymethylation ye-cellulose, i-carboxymethyl cellulose (CMC) itholakala.Isixazululo saso samanzi sinemisebenzi yokuqina, ukwenza ifilimu, ukubopha, ukugcinwa kwamanzi, ukuvikelwa kwe-colloidal, i-emulsification nokumiswa.Isetshenziswa kakhulu ezimbonini ze-petroleum, zokudla, zemithi, zendwangu kanye nezokwenza amaphepha.Ingenye ye-cellulose ethers ebaluleke kakhulu.Ngobuchwepheshe bethu besikhathi eside ekuhwebeni kwemikhiqizo yamakhemikhali, ingabe sikunikeza izeluleko zochwepheshe ngemikhiqizo nezixazululo eziklanyelwe injongo yakho ethile.Siyajabula ukukusiza ukuthi ukhethe izinto ezikufanelekelayo.Vele uchofoze ukuze uthole izinhlelo zokusebenza embonini yakho: I-CMC ekudleni, ku-petroleum, ekuphrinteni nasekudayeni, izitsha zobumba, umuthi wokuxubha amazinyo, i-beneficiation entantayo, ibhethri, i-coating, i-putty powder kanye nokwenza amaphepha.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Imodeli ye-CMC yebanga lephepha: NX-1/3/5 , NX-10/30/100, NX-150/300/700
I-CMC iyisengezo esihle sokuhlanganisa, esingathuthukisa indawo yokulingana yezingubo, futhi inempahla enhle kakhulu yokunamathela kanye neyokwenza ifilimu.Ifanele ukugqokwa kokuqukethwe okuqinile okuphezulu kanye nokugqoka ngesivinini esikhulu.
I-CMC isetshenziselwa ukulinganisa indawo, okungathuthukisa ngempumelelo ukushelela, amandla kanye nokungena komoya kwephepha futhi kutholakale ukuphrinta okuhle.
I-CMC isetshenziswa ekugcineni okumanzi komshini wephepha njengesithuthukisi esihlakazayo nokugcina ukuze kuthuthukiswe ukufana namandla ephepha, ukuthuthukisa ukugcinwa kwesistimu, nokuhlinzeka ngezinga elithile lokulinganisa.

CMC-Application In Paper Industry

I-1, Indima eyinhloko ye-CMC ekuhlanganiseni kwe-pigment
- Lawula futhi ulungise i-rheology ye-coating kanye nokuhlakazeka kwe-pigment ukuze kuthuthukiswe okuqukethwe okuqinile kwe-coating;
- Yenza ukunamathela kube ne-pseudoplasticity futhi uthuthukise ijubane lokumboza;
- Thuthukisa ukugcinwa kwamanzi kwe-coating futhi uvimbele ukufuduka kwe-adhesive encibilikayo emanzini;
- Inempahla enhle yokwenza ifilimu futhi ithuthukise isicwebezelisi se-coating;
- Thuthukisa izinga lokugcinwa kwe-brightener ekunambeni futhi uthuthukise ubumhlophe bephepha;
- Thuthukisa ukusebenza kokugcoba kwe-coating, thuthukisa ikhwalithi yokugqoka futhi andise impilo yesevisi ye-scraper.
2. Iqhaza elikhulu le-CMC ekwengezeni udaka
- Thuthukisa ukusebenza kahle kwe-pulp, ukhuthaze ukulungiswa kwe-fiber, unciphise isikhathi sokushaya;
- Lungisa amandla we-pulp, uhlakaze ngokulinganayo i-fiber, uthuthukise umshini wephepha "ukukopisha ukusebenza", uthuthukise ukwakheka kwekhasi;
- Thuthukisa izinga lokugcinwa kwezithasiselo ezihlukahlukene, izigcwalisi nemicu emihle;
- Khulisa amandla okubopha phakathi kwemicu, uthuthukise izakhiwo ezibonakalayo zephepha;
- Isetshenziswa ne-ejenti yamandla eyomile nemanzi, ingathuthukisa amandla omile namanzi ephepha;
- Vikela i-rosin, i-AKD namanye ama-ejenti okulinganisa ku-pulp, thuthukisa umphumela wokulinganisa.
3. Indima enkulu ye-CMC ekulinganisweni kwendawo
- Ine-rheology enhle kanye nempahla yokwakha ifilimu;
- Yehlisa ama-pores wephepha futhi uthuthukise ukumelana kwamafutha kwephepha;
- Khulisa ukukhanya nokucwebezela kwephepha;
- Khulisa ukuqina nokushelela kwephepha futhi ulawule i-curl;
- Thuthukisa amandla angaphezulu nokumelana nokugqoka kwephepha, unciphise ukulahleka kwezinwele nempushana, futhi uthuthukise ikhwalithi yokuphrinta.
