Kutheni i-CMC idlala indima ebalulekileyo kuShishino lokwenziwa kwePhepha

I-sodium carboxymethyl cellulose (CMC) idlala indima ebalulekileyo kwishishini lokwenza iphepha ngenxa yeempawu zayo ezizodwa kunye nokusebenza. Nasi isizathu sokuba i-CMC ibalulekile ekwenzeni iphepha:

1. Ukugcinwa kunye noNcedo lweMijelo: I-CMC isebenza njengoncedo lokugcina kunye nokukhutshwa kwamanzi kwinkqubo yokwenza iphepha. Iphucula ukugcinwa kweengqungquthela ezintle, iifibers, kunye nezongezo kwi-stock stock, ukuthintela ukulahlekelwa kwabo ngexesha lokubunjwa kunye nokuphucula ukubunjwa kwephepha kunye nokufana. I-CMC ikwaphucula amanzi okuhambisa amanzi ngokwandisa isantya sokukhupha amanzi ngomnatha wocingo womatshini wephepha, ukunciphisa ixesha elifunekayo lokwenziwa kwamaphepha kunye nokomisa.
2. I-Arhente yobungakanani bangaphakathi: I-CMC isebenza njenge-arhente yokulinganisa yangaphakathi kuqulunqo lwephepha, inika ukuxhathisa kwamanzi kunye nokwamkelwa kwe-inki kwiphepha eligqityiweyo. I-adsorbs kwi-cellulose fibers kunye ne-filler particles, yenza umqobo we-hydrophobic ogxotha iimolekyuli zamanzi kunye nokunciphisa ukungena kolwelo kwisakhiwo sephepha. Ukwenziwa kobungakanani obusekwe kwi-CMC buphucula ukushicileleka, ukubanjwa kwe-inki, kunye nozinzo lwe-dimensional yeemveliso zephepha, ziphucula ukufaneleka kwazo kwiinkqubo ezahlukeneyo zokuprinta nokubhala.
3. I-Arhente yobungakanani boMphezulu: I-CMC isetyenziswa njengearhente yokulinganisa umphezulu ukukhulisa iipropathi zomphezulu wephepha, njengokuguda, ukuqaqamba, kunye nokuprintwa. Yenza ifilimu encinci phezu kwephepha lephepha, igcwalise izitenxo zomhlaba kunye nokunciphisa i-porosity. Oku kuphucula ukomelela komphezulu, ukubanjwa kwe-inki, kunye nomgangatho woshicilelo lwephepha, okukhokelela kubukhali, imifanekiso eprintiweyo edlamkileyo kunye nokubhaliweyo. I-CMC-based based sizeing formulations ikwaphucula ukuguda komphezulu kunye nokubaleka kwephepha kushicilelo nokuguqula izixhobo.
4. I-Wet End Additive: Kwisiphelo esimanzi somatshini wephepha, i-CMC isebenza njengesongezo sokuphela esimanzi sokuphucula ukubunjwa kwephepha kunye namandla ephepha. Iphucula i-flocculation kunye nokugcinwa kweefiber kunye nezihluzi, ezikhokelela ekubunjweni okungcono kwamaphepha kunye nokufana. I-CMC ikwanyusa amandla okudibanisa phakathi kweentsinga, okukhokelela kukuqina okuphezulu kwephepha, ukuxhathisa kweenyembezi, kunye nokugqabhuka kwamandla. Oku kuphucula umgangatho jikelele kunye nokuqina kwemveliso yephepha eligqityiweyo.
5. I-Pulp Dispersant kunye ne-Agglomerate Inhibitor: I-CMC isebenza njenge-pulp dispersant kunye ne-agglomerate inhibitor kwi-papermaking, ukukhusela i-agglomeration kunye ne-agglomeration ye-cellulose fibers kunye nezohlwayo. Isasaza iintsinga kunye nezohlwayo ngokulinganayo kulo lonke isitokhwe sephepha, ukunciphisa i-fiber bundling kunye nokuphucula ukubunjwa kwamaphepha kunye nokufana. I-CMC-based dispersants iphucula ukusebenza kakuhle kokusetyenzwa kwepulp kunye nokunciphisa ukwenzeka kweziphene ezinje ngamabala, imingxunya, kunye nemivimbo kwiphepha eligqityiweyo.
6. Isibophelelo sokugquma umphezulu: I-CMC isetyenziswa njengesibophelelo kwimixube yokwaleka komphezulu yamaphepha agqunyiweyo kunye nebhodi yephepha. Ibophelela amasuntswana e-pigment, afana ne-calcium carbonate okanye i-kaolin, kumphezulu we-substrate yephepha, yenze umgca ogudileyo, ofanayo wokugquma. Iingubo ezisekwe kwi-CMC ziphucula ukuprintwa, ukuqaqamba, kunye neempawu ezibonakalayo zamaphepha agqunyiweyo, ziphucula inkangeleko yazo kunye nokuthengiswa komgangatho ophezulu wokushicilela kunye nokupakishwa kwezicelo.
7. Ukuzinza kokusiNgqongileyo: I-CMC ibonelela ngeenzuzo zokusingqongileyo kwishishini lokwenza iphepha njengento ehlaziyiweyo, enokubola, kunye neyongezo engenatyhefu. Ithatha indawo ye-synthetic sizeing agents, izisasazi, kunye nezibophelelo zokugquma, inciphisa impembelelo yokusingqongileyo yokwenziwa kunye nokulahlwa kwephepha. Iimveliso zephepha ezisekwe kwi-CMC ziyakwazi ukurisayiklishwa kwaye zivundiswe, zinegalelo kwiindlela ezizinzileyo zamahlathi kunye namalinge oqoqosho olujikelezayo.

I-sodium carboxymethyl cellulose (CMC) idlala indima ebaluleke kakhulu kwishishini lokwenza iphepha ngokuphucula ukubunjwa kwephepha, amandla, iipropati zomhlaba, ukuprintwa, kunye nokuzinza kwendalo. Iimpawu zayo ezinomsebenzi omninzi zenza ukuba ibe yinto eyongeziweyo yokongeza umgangatho, ukusebenza, kunye nokhuphiswano lwemarike yephepha kunye neemveliso zephepha kwizicelo ezahlukeneyo.
