Sodium carboxymethylcellulose (CMC) ke motsoako oa lik'hemik'hale o sebetsang ka mokhoa o fapaneng o nang le ts'ebeliso e atileng liindastering tse fapaneng, haholo indastering ea ho etsa pampiri. Motsoako ona oa lik'habohaedreite o tsoa ho cellulose, e leng polima ea tlhaho e fumanehang maboteng a lisele tsa semela. CMC e entsoe ka ho arabela selulose ka sodium hydroxide le chloroacetic acid kapa letsoai la eona la sodium. Motsoako o hlahisoang o qhibiliha ka metsing 'me o na le thepa e ikhethang e etsang hore e be ea bohlokoa lits'ebetsong tse ngata.
1. Tokiso ea Pulp:
Hangata CMC e sebelisoa e le karolo qetellong ea metsi ea mokhoa oa ho etsa pampiri. E thusa ho hasana ha likhoele le li-additives tse ling ka metsing, ho thusa ho thehoa ha makhasi a homogeneous slurry.
Bokhoni ba eona bo phahameng ba ho boloka metsi bo thusa ho boloka ho ts'oana ha pulp slurry, ho netefatsa ho ts'oana ha ho etsoa ha pampiri.
2. Ho boloka le ho ntša metsi:
E 'ngoe ea liqholotso tse ka sehloohong tsa ho etsa pampiri ke ho eketsa ho boloka likhoele le li-additives ha u ntse u ntša metsi ka mokhoa o nepahetseng ho tloha makhasi. CMC e thusa ho sebetsana le phephetso ena ka ho ntlafatsa litšoaneleho tsa polokelo le tsa metsi.
E le thuso ea ho boloka, CMC e tlamella likhoele le likotlo, ho thibela tahlehelo ea bona nakong ea ho thehoa ha pampiri ea pampiri.
CMC e ntlafatsa kemiso ea metsi ka ho eketsa lebelo leo metsi a ntšoang ka lona ho tsoa makhasing, e leng se lebisang ho potlakisang metsi le lebelo le phahameng la mochini oa pampiri.
3. Matlafatso ea Matla:
CMC e kenya letsoho ho matla a pampiri, ho kenyelletsa matla a thata, ho hanyetsa meokho, le matla a phatlohileng. E etsa marang-rang ka har'a matrix a pampiri, ka katleho e matlafatsa sebopeho le ho ntlafatsa thepa ea eona ea mechine.
Ka ho ntlafatsa matla a pampiri, CMC e lumella tlhahiso ea limaraka tse tšesaane tsa pampiri ntle le ho tela ts'ebetso, kahoo e nolofalletsa ho boloka litšenyehelo le ho sebetsa hantle ha lisebelisoa.
4. Boholo ba Sebaka:
Ho leka-lekanya bokaholimo ke mohato oa bohlokoa oa ho etsa pampiri o kenyelletsang ho sebelisa karolo e tšesaane ea lisebelisoa tsa boholo holim'a pampiri ho ntlafatsa ho hatisoa ha eona, ho boreleli le ho thibela metsi.
CMC e hiriloe e le setsi sa boholo ba bokaholimo ka lebaka la thepa ea eona ea ho etsa lifilimi le bokhoni ba ho matlafatsa matla a bokaholimo le boreleli. E etsa seaparo se ts'oanang holim'a pampiri, se fella ka ho boloka enke e ntlafetseng le boleng ba khatiso.
5.Retention Aid bakeng sa Fillers le Pigments:
Ha ho etsoa lipampiri, li-fillers le li-pigments hangata li eketsoa ho ntlafatsa thepa ea pampiri joalo ka opacity, khanya, le khatiso. Leha ho le joalo, li-additives tsena li ka ba le tšekamelo ea ho lahleheloa ke metsi nakong ea mokhoa oa ho etsa pampiri.
CMC e sebetsa e le thuso ea ho boloka li-filler le li-pigments, e thusa ho li tiisa ka har'a matrix a pampiri le ho fokotsa tahlehelo ea tsona nakong ea ho etsoa le ho omisoa.
6.Taolo ea Thepa ea Rheological:
Rheology e bua ka mokhoa oa ho phalla ha maro, ho kenyelletsa le li-pulp slurries, ka har'a mokhoa oa ho etsa pampiri. Ho laola thepa ea rheological ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea ts'ebetso le boleng ba sehlahisoa.
CMC e susumetsa rheology ea pulp slurries ka ho fetola viscosity ea bona le litšobotsi tsa phallo. E ka sebelisoa ho lokisa thepa ea rheological ea makhasi hore e lumellane le litlhoko tse khethehileng tsa ts'ebetso, joalo ka ho ntlafatsa ts'ebetso ea mochini le sebopeho sa maqephe.
7. Litlhokomelo tsa Tikoloho:
Sodium carboxymethylcellulose ka kakaretso e nkuoa e le botsoalle tikolohong, kaha e nkiloe mehloling ea selulose e nchafalitsoeng mme e ka senyeha habonolo.
Tšebeliso ea eona ho etsa pampiri e ka kenya letsoho ho nts'etsopele ea lihlahisoa tsa pampiri tse tsitsitseng haholoanyane ka ho nolofalletsa mekhoa ea tlhahiso e sebetsang hantle le ho ntlafatsa ts'ebetso ea lihlahisoa.
sodium carboxymethylcellulose (CMC) e bapala karolo e ngata indastering ea ho etsa pampiri, e sebetsa e le tlatsetso e fapaneng e ntlafatsang likarolo tse fapaneng tsa ts'ebetso ea tlhahiso ea pampiri. Ho tloha ho tokiso ea pulp ho isa boholo ba bokaholimo, CMC e kenya letsoho ntlafatsong ea ts'ebetso ea ts'ebetso, boleng ba sehlahisoa le ts'ireletso ea tikoloho. Motsoako oa eona o ikhethang oa thepa o etsa hore e be bohlokoa haholo ho baetsi ba pampiri ba batlang ho ntlafatsa ts'ebetso le ho fihlela litlhoko tse ntseng li tsoela pele tsa mmaraka.
