CMC (carboxymethyl cellulose) indastering ea ho etsa pampiri ke tlatsetso ea bohlokoa e sebelisetsoang ho ntlafatsa boleng le ts'ebetso ea pampiri. CMC ke motsoako oa polymer o qhibilihang ka metsi o nang le thepa e ntle ea tokiso ea viscosity mme o bapala karolo ea bohlokoa ho etsa pampiri.
1. Lintho tsa motheo tsa CMC
CMC e tsoa ho cellulose, e entsoeng ka ho arabela karolo ea hydroxyl ea selulose ka chloroacetic acid. E na le bokhoni bo botle ba ho qhibiliha ha metsi le bokhoni ba ho fetola viscosity. CMC e etsa tharollo ea viscous ka mor'a ho qhibiliha ka metsing, e etsang hore e be molemo haholo lits'ebetsong tse fapaneng tsa indasteri.
2. Karolo ea CMC indastering ea ho etsa pampiri
Ts'ebetsong ea ho etsa pampiri, CMC e sebelisoa haholo-holo e le sekhomaretsi, setenya le se tsitsitseng. Mesebetsi ea eona e kenyelletsa:
2.1 Ntlafatsa matla a pampiri
CMC e ka ntlafatsa momahano le tsitsipano ea pampiri ka nepo, 'me ea ntlafatsa ho hanyetsa ho lla le ho phutha pampiri. Mokhoa oa eona oa ts'ebetso ke ho etsa hore pampiri e be thata le ho tšoarella haholoanyane ka ho matlafatsa matla a tlamahano lipakeng tsa likhoele tsa pulp.
2.2 Ntlafatsa ho phatsima le boreleli holim'a pampiri
Ho eketsa CMC ho ka ntlafatsa boleng ba pampiri le ho etsa hore bokaholimo ba pampiri bo be bonolo. E ka tlatsa ka katleho likheo holim'a pampiri 'me ea fokotsa boima ba holim'a pampiri, ka tsela eo e ntlafatsa khanya le ho ikamahanya le maemo a pampiri.
2.3 Laola viscosity ea pulp
Nakong ea ts'ebetso ea ho etsa pampiri, CMC e khona ho laola ka nepo viscosity ea makhasi le ho netefatsa hore metsi le ho tšoana ha pulp. Viscosity e nepahetseng e thusa ho aba makhasi ka ho lekana, ho fokotsa liphoso tsa pampiri, le ho ntlafatsa katleho ea tlhahiso.
2.4 Ntlafatsa ho boloka metsi a pulp
CMC e na le bokhoni bo botle ba ho boloka metsi mme e ka fokotsa tahlehelo ea metsi nakong ea ts'ebetso ea ho bopa. Sena se ka fokotsa ho fokotseha ha pampiri le mathata a deformation a hlahang nakong ea ho omisa, ka hona ho ntlafatsa botsitso ba pampiri.
3. Phetoho ea viscosity ea CMC
Viscosity ea CMC ke parameter ea bohlokoa bakeng sa phello ea eona ts'ebetsong ea ho etsa pampiri. Ho latela litlhoko tse fapaneng tsa tlhahiso, viscosity ea CMC e ka fetoloa ka ho fetola mahloriso a eona le boima ba limolek'hule. Ka ho khetheha:
3.1 Phello ea boima ba molek'hule
Boima ba limolek'hule tsa CMC bo na le phello e tobileng ho viscosity ea eona. CMC e nang le boima bo boholo ba limolek'hule hangata e na le viscosity e phahameng, kahoo boima ba limolek'hule bo phahameng ba CMC bo sebelisoa lits'ebetsong tse hlokang viscosity e phahameng. CMC e tlase ea boima ba limolek'hule e loketse liketsahalo tse hlokang viscosity e tlase.
3.2 Phello ea mohopolo oa tharollo
Khokahano ea tharollo ea CMC le eona ke ntlha ea bohlokoa e amang viscosity. Ha re bua ka kakaretso, ha tharollo ea CMC e phahame, ho ba le viscosity e kholoanyane. Ka hona, tlhahisong ea 'nete, khatello ea tharollo ea CMC e hloka ho lokisoa ho latela litlhoko tse ikhethileng ho fihlela boemo bo hlokahalang ba viscosity.
4. Litemoso mabapi le ts'ebeliso ea CMC
Ha u sebelisa CMC ts'ebetsong ea ho etsa pampiri, lintlha tse latelang li lokela ho hlokomeloa:
4.1 Karolelano e nepahetseng
Chelete ea CMC e ekelitsoeng e lokela ho fetoloa ho latela litlhoko tse khethehileng tsa pampiri. Haeba ho eketsoa ho hongata haholo, ho ka etsa hore viscosity ea pulp e be holimo haholo 'me e ame mokhoa oa tlhahiso; haeba e sa lekana, phello e lebeletsoeng e ka 'na ea se ke ea finyelloa.
4.2 Taolo ea ts'ebetso ea ho qhala
CMC e hloka ho qhibiliha ka metsing a batang ho qoba ho senyeha nakong ea ho futhumatsa. Ts'ebetso ea ho qhala e lokela ho ts'oaroa ka botlalo ho netefatsa hore CMC e qhaloa ka botlalo le ho qoba ho kopana.
4.3 Phello ea boleng ba pH
Ts'ebetso ea CMC e tla angoa ke boleng ba pH. Tlhahisong ea pampiri, mofuta o loketseng oa pH o lokela ho bolokoa ho netefatsa phello e ntle ka ho fetisisa ea CMC.
CMC e bapala karolo ea bohlokoa indastering ea ho etsa pampiri, 'me bokhoni ba eona ba tokiso ea viscosity bo ama ka kotloloho boleng le ts'ebetso ea pampiri. Ka ho khetha le ho sebelisa CMC hantle, matla, khanya, boreleli le katleho ea tlhahiso ea pampiri li ka ntlafatsoa haholo. Leha ho le joalo, ts'ebetsong ea 'nete, mahloriso le viscosity ea CMC e hloka ho lokisoa hantle ho latela litlhoko tse khethehileng tsa tlhahiso ho netefatsa phello e ntle ka ho fetisisa.
