I-CMC isebenzisa embonini yamaphepha

I-Carboxymethylcelcelcellellose (CMC) isetshenziswa kabanzi embonini yamaphepha ngezindawo zayo eziguquguqukayo njenge-polymer esondelana amanzi. Kususelwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo, ngenqubo yokuguqulwa kwamakhemikhali eyethula amaqembu e-carboxymethyl. I-CMC isetshenziswa ezigabeni ezahlukahlukene zokukhiqizwa kwamaphepha ukwenza ngcono izakhiwo zephepha futhi zithuthukise ukusebenza kwezindlela zokukhiqiza. Nazi zisetshenziswa eziningana zokhiye we-CMC embonini yamaphepha:

1. Ukulinganisa okungaphezulu:
   • I-CMC isetshenziswa njenge-ejenti yokuhlanza indawo ephepheni yephepha. Kuthuthukisa izakhiwo ezingaphezulu kwephepha, njengokumelana kwamanzi, ukuphrinta kanye nokuhlaselwa kwe-inki. I-CMC yakha ifilimu elincanyana ephepheni elingaphezulu, lifaka isandla kwikhwalithi yokuphrinta engcono kanye nokunciphisa ukungena kwe-ink.
2. Ukulinganisa kwangaphakathi:
   • Ngaphezu kokugcona komhlaba, i-CMC iqashwa njenge-ejenti yezandla yangaphakathi. Kuthuthukisa ukumelana nephepha lokungena ngotshwala, kubandakanya namanzi nokuphrinta ama-inks. Lokhu kunomthelela emandleni nokuqina kwephepha.
3. Ukugcinwa kanye nosizo lokudonsa:
   • I-CMC isebenza njengokugcinwa kokugcinwa kanye nosizo lokudonsa ngesikhathi senqubo yokuphambana. Kuthuthukisa ukugcinwa kwemicu nezinye izengezo ekhasini lephepha, okuholela ekwakhekeni okungcono nokukhulisa amandla ephepha. I-CMC ibuye ikwazi ukudonsa amanzi, ukunciphisa isikhathi esidingayo ukuze kususwe amanzi epulp.
4. Isengezo se-Wet-End:
   • I-CMC ingezwa endaweni emanzi yenqubo yokuphamba njengosizo lokugcina kanye ne-flecculant. Kuyasiza ukulawula ukuhamba nokusatshalaliswa kwemicu ephepheni ama-slurry, ngcono ukusebenza kahle komshini wephepha.
5. Ukulawulwa kwe-Pulp Viscosity:
   • I-CMC isetshenziselwa ukulawula i-viscosity ye-pulp kwinqubo yokuphambana. Lokhu kuqinisekisa ukusatshalaliswa okufanayo kwemicu kanye nezithasiselo, ukukhuthaza ukwakheka okungcono kweshidi kanye nokunciphisa ubungozi bezinkinga zamaphepha.
6. Amandla athuthukisiwe:
   • Ukungezwa kwe-CMC kunomthelela ezizandleni zamaphepha, kufaka phakathi amandla ashukumisayo namandla okuqhuma. Lokhu kubaluleke kakhulu ukukhiqiza amaphepha ngokuqina okuthuthukile nokusebenza.
7. Isengezo:
   • I-CMC isetshenziswa njengesengezo ekunikezelweni kwenhlanganisela kwamaphepha ahlanganisiwe. Inomthelela ku-Rheology kanye nokuqina kokuhlanganiswa, ukwenza ngcono ubushelelezi kanye nekhwalithi yokuphrinta yamaphepha ahlanganisiwe.
8. Ukulawulwa kwePulp PH:
   • I-CMC ingaqashwa ukulawula i-PH ye-PULP ukumiswa. Ukugcina izinga le-PH elifanele kubalulekile ekwakheni ukusebenza kwamakhemikhali ahlukahlukene wepapermang.
9. Ukwakheka kanye nokufana kweshidi:
   • I-CMC AIDS ekuthuthukiseni ukwakheka kanye nokufana kwamashidi ephepha. Kuyasiza ukulawula ukusatshalaliswa kwemicu nezinye izinto, okuholela emaphepheni anezakhiwo ezingaguquki.
10. Usizo lokugcina ama-filler kanye nezithasiselo:
    • I-CMC isebenza njengosizo lokugcina ama-filler nezinye izengezo ekwakhekeni kwamaphepha. Kuthuthukisa ukugcinwa kwalezi zinto ezisetshenziselwa ephepheni, okuholela ekuphrintiwe kangcono nekhwalithi yephepha lonke.
11. Izinzuzo zezemvelo:
    • I-CMC iyisengezo se-biodegradable nemvelo enobungani, ihambisana nokugxila komkhakha ezindleleni ezinzile.

Ngamafuphi, i-carboxymethylcellulose (CMC) idlala indima ebalulekile embonini yamaphepha, ifaka isandla ekuthuthukisweni kwezakhiwo zamaphepha, ukusebenza kwezindlela zokukhiqiza, kanye nekhwalithi ephelele yemikhiqizo yamaphepha. Izicelo zayo eziguquguqukayo ku-sunging sunging, ukufakwa kwangaphakathi, usizo lokugcina, nezinye izindima zikwenza kube yisengezo esibalulekile ezigabeni ezahlukahlukene zokukhiqizwa kwamaphepha.
