Kungani i-CMC idlala indima ebalulekile Embonini Yokwenza Amaphepha
I-sodium carboxymethyl cellulose (CMC) idlala indima ebalulekile embonini yokwenza iphepha ngenxa yezakhiwo zayo eziyingqayizivele nokusebenza kwayo. Nakhu ukuthi kungani i-CMC ibalulekile ekwenzeni iphepha:
- Ukugcinwa Nosizo Lokukhipha Indle: I-CMC isebenza njengosizo lokugcina nokukhipha amanzi enqubweni yokwenza iphepha. Ithuthukisa ukugcinwa kwezinhlayiya ezinhle, imicu, kanye nezithasiselo esitokisini sephepha, ukuvimbela ukulahlekelwa kwabo ngesikhathi sokwakheka nokuthuthukisa ukwakheka kwephepha nokufana. I-CMC iphinde ithuthukise ukugeleza kwamanzi ngokwandisa izinga lokugeleza kwamanzi nge-mesh yocingo lomshini wephepha, inciphise isikhathi esidingekayo sokwakhiwa kweshidi nokomiswa.
- I-ejenti yokulinganisa yangaphakathi: I-CMC isebenza njenge-ejenti yokulinganisa yangaphakathi ekwenziweni kwephepha, idlulisela ukumelana kwamanzi nokwamukelwa kweyinki ephepheni eliqediwe. Ikhangisa kuma-cellulose fibers kanye nezinhlayiya zokugcwalisa, yenza umgoqo we-hydrophobic oxosha ama-molecule wamanzi futhi wehlise ukungena koketshezi esakhiweni sephepha. Ukwakhiwa kosayizi okususelwe ku-CMC kuthuthukisa ukuphrinta, ukubamba kukayinki, nokuzinza kobukhulu bemikhiqizo yephepha, kuthuthukisa ukufaneleka kwayo kwezinhlelo zokusebenza ezihlukahlukene zokuphrinta nokubhala.
- I-Surface Sizing Agent: I-CMC isetshenziswa njenge-ejenti yokulinganisa indawo ukuze kuthuthukiswe izakhiwo zephepha, njengokushelela, ukucwebezela, nokuphrinta. Yakha ifilimu elincanyana ebusweni bephepha lephepha, ligcwalise ukungahambi kahle kwendawo futhi linciphise i-porosity. Lokhu kuthuthukisa amandla angaphezulu, ukubamba kukayinki, kanye nekhwalithi yokuphrinta yephepha, okuholela ezithombeni eziphrintiwe ezibukhali, ezigqama kakhulu nombhalo. Ukwakheka kokulinganisa kwendawo okususelwe ku-CMC nakho kuthuthukisa ukushelela kwendawo kanye nokusebenza kwephepha ekuphrinteni nasekuguquleni okokusebenza.
- I-Wet End Additive: Ekugcineni okumanzi komshini wephepha, i-CMC isebenza njengesithasiselo sokuphela esimanzi ukuthuthukisa ukwakheka kwephepha namandla eshidi. Ithuthukisa i-flocculation kanye nokugcinwa kwama-fibers nama-filler, okuholela ekwakhiweni okungcono kweshidi nokufana. I-CMC iphinde ikhulise amandla okubopha phakathi kwemicu, okuholela ekuqineni okukhulu kwephepha, ukumelana nezinyembezi, namandla okuqhuma. Lokhu kuthuthukisa ikhwalithi jikelele kanye nokuqina komkhiqizo wephepha oqediwe.
- I-Pulp Dispersant kanye ne-Agglomerate Inhibitor: I-CMC isebenza njenge-pulp dispersant kanye ne-agglomerate inhibitor ekwenzeni iphepha, ivimbela ukuhlangana kanye nokuhlanganisa kabusha amafayili e-cellulose nezinhlawulo. Ihlakaza imicu kanye nezinhlawulo ngokulinganayo kuso sonke isitokwe sephepha, inciphisa ukunqwabelana kwefiber futhi ithuthukise ukwakheka kweshidi nokufana. Izisabalali ezisekelwe ku-CMC zithuthukisa ukusebenza kahle kokucubungula uginindela futhi zehlise ukuvela kweziphambeko njengamachashaza, izimbobo, nemigqa ephepheni eliqediwe.
- I-Surface Coating Binder: I-CMC isetshenziswa njengesibophezelo ekwakhiweni kokumboza okungaphezulu kwamaphepha amboziwe kanye nebhodi lephepha. Ibophela izinhlayiya ze-pigment, njenge-calcium carbonate noma i-kaolin, ebusweni be-substrate yephepha, yenze ungqimba olubushelelezi, olufana nolufana. Izembatho ezisekelwe ku-CMC zithuthukisa ukuphrinta, ukugqama, kanye nezakhiwo zokubona zamaphepha amboziwe, zithuthukisa ukubukeka kwazo nokuthengiseka ekuphrinteni nasekupakisheni kwekhwalithi ephezulu.
- Ukusimama Kwemvelo: I-CMC inikeza izinzuzo zemvelo embonini yokwenza iphepha njengesithako esivuselelekayo, esibolayo, nesingenabuthi. Ingena esikhundleni se-synthetic sizing agents, izisabalalisi, nezibophezelo zokuhlanganisa, inciphisa umthelela wemvelo wokukhiqiza nokulahlwa kwephepha. Imikhiqizo yephepha esekwe ku-CMC iyasebenziseka kabusha futhi iyavuthwa, inikela ezinkambisweni zamahlathi ezisimeme kanye nezinhlelo zomnotho eziyindilinga.
I-sodium carboxymethyl cellulose (CMC) idlala indima ebalulekile embonini yokwenza iphepha ngokuthuthukisa ukwakheka kwephepha, amandla, izakhiwo ezingaphezulu, ukuphrinta, nokusimama kwemvelo. Izakhiwo zayo ezinemisebenzi eminingi ziyenza ibe isithasiselo esisebenza ngezindlela eziningi sokuthuthukisa ikhwalithi, ukusebenza, nokuncintisana kwemakethe kwemikhiqizo yamaphepha nebhodi lephepha ezinhlelweni ezihlukene.
