1.Selelekela
Hydroxyethyl cellulose (HEC) ke polymer e feto-fetohang e nkiloeng ho selulose, e sebelisoang haholo liindastering tse fapaneng ka lebaka la thepa ea eona e ntle ea rheological, bokhoni ba ho boloka metsi, le ho lumellana le lisebelisoa tse ling. Sebakeng sa tlhahiso ea enke, HEC e sebetsa e le karolo ea bohlokoa, e fanang ka litšobotsi tse lakatsehang tse kang taolo ea viscosity, botsitso le ho khomarela.
2.Ho Utloisisa HEC ka Liqapi tsa Enke
Ka libopeho tsa enke, HEC e sebetsa e le moemeli o teteaneng, e matlafatsang viscosity ho finyella litšobotsi tse ntle tsa phallo. Sebopeho sa eona sa hydrophilic se e nolofalletsa ho boloka metsi ka nepo ka har'a matrix a enke, ho thibela ho omisa pele ho nako le ho boloka botsitso nakong ea lits'ebetso tsa khatiso. Ho feta moo, HEC e bonts'a boitšoaro ba ho kuta, ho bolelang hore e fokotsa viscosity tlas'a khatello ea ho kuta, e nolofalletsa ts'ebetso e bonolo ho li-substrates tse fapaneng.
3.Melemo ea ho Kenyelletsa HEC ho Li-Inks
Taolo ea Viscosity: HEC e fana ka taolo e nepahetseng holim'a viscosity ea enke, ea bohlokoa bakeng sa ho fihlela boleng bo lakatsehang ba khatiso le ts'ebetso ho pholletsa le mekhoa e fapaneng ea khatiso.
Botsitso bo Ntlafetseng: Ka ho etsa matrix a tsitsitseng, HEC e thibela sedimentation le karohano ea mekhahlelo, ho etsa bonnete ba hore kabo ea enke e ts'oanang le botsitso ba nako e telele.
Ntlafatso ea Khomarelo: Thepa ea sekhomaretsi ea HEC e khothalletsa ho khomarela hamolemo pakeng tsa enke le substrate, e leng se etsang hore ho be le botsitso bo ntlafetseng ba khatiso le ho hanyetsa ho senya.
Paballo ea Metsi: Bokhoni ba HEC ba ho boloka metsi bo fokotsa mouoane nakong ea khatiso, ho fokotsa nako ea ho omisa ha enke le ho thibela ho koaloa ha nozzle ho liprinta tsa inkjet.
Ho lumellana: HEC e lumellana le mefuta e mengata ea li-additives le li-pigment tse ngata, tse lumellang hore ho be le mefuta e mengata ea libopeho tsa enke tse lumellanang le litlhoko tse khethehileng tsa khatiso.
Setsoalle sa Tikoloho: Joalo ka polymer e thehiloeng ho bio, HEC e kenya letsoho ho ts'oarella ha ho etsoa ha enke, ho ikamahanya le mekhoa e metle ea tikoloho indastering ea khatiso.
4. Litlhokomelo tse sebetsang bakeng sa Kopo ea HEC
Optimal Concentration: The concentration of HEC in inki formulations e lokela ho ntlafatsoa ka hloko ho fihlela viscosity e lakatsehang ntle le ho senya thepa e meng ea enke.
Teko ea Tumellano: Pele ho tlhahiso e kholo, tlhahlobo ea tšebelisano le likarolo tse ling tsa enke le li-substrates li bohlokoa ho netefatsa botsitso le ts'ebetso.
Taolo ea Boholo ba Karolo: Kabo ea boholo ba likarolo tsa HEC e lokela ho laoloa ho thibela ho koaloa ha thepa ea khatiso, haholo-holo mekhoeng ea khatiso ea inkjet.
Maemo a Polokelo: Maemo a nepahetseng a polokelo, ho kenyeletsoa taolo ea mocheso le mongobo, a bohlokoa bakeng sa ho boloka botšepehi ba libopeho tsa enke tse thehiloeng ho HEC le ho lelefatsa nako ea ho phela.
Tumellano ea Taolo: Ho tsamaellana le litekanyetso tsa taolo, joalo ka tse mabapi le polokeho, bophelo bo botle, le phello ea tikoloho, li lokela ho netefatsoa ha ho sebelisoa HEC mefuteng ea enke.
5.Case Studies le Applications
Ho hatisoa ha Flexographic: Li-inks tse thehiloeng ho HEC li atisa ho sebelisoa khatisong ea flexographic bakeng sa thepa ea ho paka, e fanang ka khatiso e babatsehang, ho khomarela le ho lumellana ha mebala.
Khatiso ea Textile: Khatisong ea masela, HEC e fana ka taolo ea viscosity le ho hlatsoa kapele ho li-inks, ho netefatsa hore ho na le likhatiso tse matla le tse tšoarellang maselang a fapaneng.
Khatiso ea Inkjet: HEC e sebetsa e le karolo ea bohlokoa mefuteng ea inkjet, e fana ka botsitso ba viscosity le ho thibela ho koaloa ha nozzle, haholo-holo lits'ebetsong tsa khatiso tse potlakileng.
Khatiso ea Gravure: Li-inks tse thehiloeng ho HEC khatisong ea gravure li bonts'a thepa ea phallo e phahameng le ho khomarela, e hlahisang litšoantšo tsa boleng bo holimo holim'a likarolo tse fapaneng tse kang pampiri, polasetiki le tšepe.
Hydroxyethyl cellulose (HEC) e bapala karolo ea bohlokoa mekhoeng ea enke lits'ebetsong tse fapaneng tse fapaneng tsa khatiso, e fana ka taolo ea viscosity, botsitso le ho khomarela. Ho feto-fetoha ha eona, hammoho le botsoalle ba tikoloho, ho etsa hore e be khetho e ratoang ho baetsi ba enke ba batlang ho ntlafatsa boleng ba khatiso le ts'ebetso ha ba ntse ba latela mekhoa e tsitsitseng. Ka ho utloisisa mekhoa le melemo ea HEC mefuteng ea enke, bahatisi ba ka sebelisa bokhoni ba bona ho fihlela litholoana tse phahameng mesebetsing ea bona ea khatiso.
