I-CMC isebenzisa kuShishino lwamaPhepha

ICarboxymethylcellulose (CMC) isetyenziswa kakhulu kushishino lwephepha ngenxa yeempawu zayo eziguquguqukayo njengepolima enyibilikayo emanzini. Ithathwe kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zesityalo sesityalo, ngokusebenzisa inkqubo yokuguqulwa kweekhemikhali eyazisa amaqela e-carboxymethyl. I-CMC isetyenziswa kumanqanaba ahlukeneyo emveliso yephepha ukuphucula iimpawu zephepha kunye nokuphucula ukusebenza kakuhle kweenkqubo zokuvelisa. Nalu usetyenziso oluninzi oluphambili lweCMC kushishino lwamaphepha:

1. Ubungakanani boMphezulu:
   • I-CMC isetyenziswa njenge-arhente yokulinganisa umphezulu kwimveliso yamaphepha. Iphucula iipropati ezingaphezulu zephepha, ezifana nokuxhathisa kwamanzi, ukuprintwa, kunye nokwamkelwa kwe-inki. I-CMC yenza ifilim ebhityileyo kumphezulu wephepha, inegalelo kumgangatho ongcono woshicilelo kunye nokunciphisa ukungena kwe-inki.
2. Ubungakanani bangaphakathi:
   • Ukongeza kubungakanani bomphezulu, iCMC iqeshwe njengearhente yangaphakathi. Yandisa ukuxhathisa kwephepha ekungeneni ngolwelo, kubandakanywa amanzi kunye nee-inki zokushicilela. Oku kufaka isandla kumandla kunye nokuqina kwephepha.
3. Ugcino kunye noNcedo lokuGutyulwa kwamanzi:
   • I-CMC isebenza njengogcino kunye noncedo lokuhambisa amanzi ngexesha lenkqubo yokwenza iphepha. Iphucula ukugcinwa kweefibers kunye nezinye izongezo kwiphepha lephepha, okukhokelela ekubunjweni okungcono kunye nokwandisa amandla ephepha. I-CMC ikwanceda ekukhupheni amanzi, ukunciphisa ixesha elithathwayo ukuba amanzi asuswe kwipulp yephepha.
4. Isiphelo Somanzi Songezo:
   • I-CMC yongezwa kwisiphelo esimanzi senkqubo yokwenza iphepha njengoncedo lokugcinwa kunye ne-flocculant. Inceda ukulawula ukuhamba kunye nokusabalalisa iifayili kwi-slurry yephepha, ukuphucula ukusebenza kakuhle komatshini wephepha.
5. Ukulawulwa kwePulp Viscosity:
   • I-CMC isetyenziselwa ukulawula i-viscosity ye-pulp kwinkqubo yokwenza iphepha. Oku kuqinisekisa ukuhanjiswa okufanayo kweefibers kunye nezongezelelo, ukukhuthaza ukubunjwa kwamaphepha angcono kunye nokunciphisa umngcipheko weephene zephepha.
6. Amandla aphuculweyo:
   • Ukongezwa kwe-CMC kunegalelo kumandla eepropathi zephepha, kubandakanywa amandla okuqina kunye nokugqabhuka kwamandla. Oku kubaluleke ngakumbi ekuveliseni amaphepha anokuqina okuphuculweyo kunye nokusebenza.
7. Ukongeza kokutyabeka:
   • I-CMC isetyenziswa njengesongezo kwiindlela zokugquma amaphepha agqunyiweyo. Igalelo kwi-rheology kunye nokuzinza kwengubo, ukuphucula ukuguquguquka kunye nomgangatho wokushicilela wamaphepha adibeneyo.
8. Ukulawulwa kwePulp pH:
   • I-CMC inokuqeshwa ukulawula i-pH yokunqunyanyiswa kwepulp. Ukugcina inqanaba le-pH elifanelekileyo kubalulekile ekuphuculeni ukusebenza kweekhemikhali ezahlukeneyo zokwenza amaphepha.
9. Ulwakhiwo kunye noKufana kwePhepha:
   • I-CMC inceda ekuphuculeni ukusekwa kunye nokufana kwamaphepha ephepha. Inceda ukulawula ukuhanjiswa kweefiber kunye nezinye izinto, okubangela ukuba amaphepha aneempawu ezihambelanayo.
10. Ugcino loNcedo kwiiFili kunye nezongezo:
    • I-CMC isebenza njengoncedo lokugcina izihluzi kunye nezinye izongezo kuqulunqo lwephepha. Iphakamisa ukugcinwa kwezi zixhobo ephepheni, ekhokelela ekushicileleni okungcono kunye nomgangatho wephepha ngokubanzi.
11. IiNzuzo zokusiNgqongileyo:
    • I-CMC sisongezo esinokonakala kwaye sinobuhlobo kokusingqongileyo, silungelelaniswa nogqaliselo lweshishini kwimisebenzi ezinzileyo.

Isishwankathelo, i-carboxymethylcellulose (CMC) idlala indima ebalulekileyo kumashishini ephepha, igalelo ekuphuculeni iimpawu zephepha, ukusebenza kakuhle kweenkqubo zokuvelisa, kunye nomgangatho jikelele weemveliso zephepha. Usetyenziso lwayo oluguquguqukayo kubungakanani bomphezulu, ubungakanani bangaphakathi, uncedo lokugcina, kunye nezinye iindima zenza ukuba ibe sisongezo esixabisekileyo kumanqanaba ahlukeneyo okwenziwa kwephepha.
