Tšebeliso ea Hydroxyethyl Cellulose ho Coatings
Hydroxyethyl cellulose (HEC)ke polymer e feto-fetohang e sebelisoang haholo liindastering tse fapaneng ka lebaka la ho tenya, ho tsitsisa le thepa ea ho etsa lifilimi. Sebakeng sa ho roala, HEC e phetha karolo ea bohlokoa ho ntlafatsa viscosity, ho ntlafatsa thepa ea rheological, le ho fana ka sebopeho se phahameng sa filimi.e bua ka phello ea HEC mabapi le ts'ebetso ea ho roala, joalo ka tšusumetso ea eona ho viscosity, leveling, sag resistance, le adhesion.
Selelekela:
Hydroxyethyl cellulose (HEC) ke polima e se nang ionic, e qhibilihang ka metsing e tsoang ho selulose ka phetoho ea lik'hemik'hale. E sebelisoa haholo liindastering tse fapaneng tse kang tsa meriana, tlhokomelo ea botho, kaho le liphahlo ka lebaka la thepa ea eona e ikhethang. Sebakeng sa ho roala, HEC e sebetsa mesebetsi e mengata, ho kenyelletsa ho teteaneng, ho tsitsisa, le ho fana ka thepa ea ho etsa lifilimi. Sengoliloeng sena se tsepamisitse maikutlo lits'ebetsong tsa HEC ka ho roala le ho hlahloba phello ea eona ts'ebetsong ea ho roala.
Lisebelisoa tsa HEC ho Coatings:
Thickening Agent:
HEC e sebetsa e le moemeli ea sebetsang hantle oa ho tenya ha ho etsoa litlolo. Ka ho eketsa viscosity ea tharollo ea ho roala, HEC e ntlafatsa botsitso ba li-pigments le li-additives, ho thibela ho rarolla kapa ho kopanya nakong ea polokelo le kopo. Viscosity ea ho roala e ka fetoloa ka ho fapanyetsana mahloriso a HEC, e leng ho lumellang hore ho be le mekhoa e hlophisitsoeng ho finyella litlhoko tse khethehileng tsa kopo. Ho feta moo, HEC e fana ka boits'oaro ba pseudoplastic, ho bolelang hore e bonts'a viscosity e fokotsehileng tlas'a ho kuta, e nolofatsa ts'ebeliso e bonolo le boemo ba ho roala.
Mofetoleli oa Rheology:
Ntle le ho tenya, HEC e sebetsa e le mofetoleli oa rheology ho li-coatings formulations. E susumetsa boitšoaro ba phallo ea ho roala, ho ntlafatsa thepa ea eona ea ts'ebeliso joalo ka brushability, sprayability, le roller-coatability. HEC e fana ka boits'oaro ba ho kuta ka ho roala, ho lumella ho sebelisoa ha bonolo ha ho ntse ho boloka viscosity ha matla a ho kuta a tlosoa. Thepa ena e molemo haholo ho fokotsa ho fafatsa nakong ea ts'ebeliso ea sefafatsi le ho netefatsa ho koaheloa ka mokhoa o ts'oanang ho li-substrates tse nang le li-profiles tse fapaneng.
Filimi ea pele:
HEC e kenya letsoho ho thehoeng ha filimi e tsoelang pele le e ts'oanang holim'a substrate. Ha seaparo se omella, limolek'hule tsa HEC li lumellana ho theha sebopeho sa filimi se kopantsoeng, se fana ka sekhomaretsi se setle ho substrate le ho matlafatsa nako e telele ea ho roala. Thepa e etsang filimi ea HEC e bohlokoa bakeng sa ho fihlela litšobotsi tse lakatsehang tse kang ho thatafala, ho tenyetseha le maemo a leholimo. Ho feta moo, lifilimi tsa HEC li bonts'a ho hanyetsa metsi hantle, ho etsa hore li tšoanelehe bakeng sa liaparo tse pepesehileng mongobo kapa maemo a mongobo o phahameng.
Kameho ea HEC ho Ts'ebetso ea Coating:
Taolo ea Viscosity:
HEC e etsa hore ho be le taolo e nepahetseng holim'a viscosity ea liphahlo, ho netefatsa phallo e nepahetseng le litšobotsi tsa boemo. Taolo e nepahetseng ea viscosity e thibela litaba tse kang ho thella, ho rotha, kapa tšireletso e sa lekanang nakong ea ts'ebeliso, e lebisang ho boleng bo ntlafetseng ba ho roala le botle bo botle. Ho feta moo, boits'oaro ba ho kuta ba HEC bo nolofalletsa ts'ebeliso e bonolo ntle le ho senya ts'ebetso ea ho roala.
Leveling le Sag Resistance:
Thepa ea rheological e fanoeng ke HEC e kenya letsoho ho phahamiseng ho hoholo le ho hanyetsa ha masela. Nakong ea kopo, HEC e fokotsa tšekamelo ea ho roala ho etsa matšoao a brush kapa roller stipple, e leng se etsang hore ho be le qetello e boreleli le e ts'oanang. Ho feta moo, HEC e ntlafatsa boitšoaro ba thixotropic ba ho roala, ho thibela ho thella kapa ho rotha holim'a libaka tse otlolohileng, ka hona ho ntlafatsa ts'ebetso ea ts'ebeliso le ho fokotsa litšila tsa thepa.
Ho khomarela:
HEC e ntlafatsa ho khomarela liphahlo ho li-substrates tse fapaneng, ho kenyeletsoa tšepe, lehong, polasetiki le konkreite. Lintho tse entsoeng ka filimi tsa HEC li theha maqhama a matla pakeng tsa ho roala le substrate, ho ntlafatsa ho khomarela nako e telele le ho tšoarella. Sena ke sa bohlokoa ka ho khetheha liphahlong tsa ka ntle tse pepesehileng maemo a thata a tikoloho, moo ho khomarela ho phetha karolo ea bohlokoa ho thibela ho hlōleha ha ho roala joalo ka ho peeling kapa delamination.
Tsoelo-pele ho HEC Technology:
Lintlafatso tsa morao tjenaHECtheknoloji e lebisitse ho nts'etsopele ea lihlahisoa tse fetotsoeng tsa HEC tse nang le litšobotsi tse ntlafetseng tsa ts'ebetso. Liphetoho tsena li kenyelletsa ho fapana ha boima ba limolek'hule, tekanyo ea ho fetola, le sebopeho sa lik'hemik'hale, tse lumellang hore ho be le litharollo tse lumellanang le litlhoko tse khethehileng tsa kopo. Ho feta moo, rea
Boiteko ba rch bo tsepamisitse maikutlo ho ntlafatsa ts'ebetso ea tikoloho ea mekhoa ea tlhahiso ea HEC, e leng se lebisang ho hlaheng ha HEC e thehiloeng ho likokoana-hloko e nkiloeng mehloling e ka nchafatsoang e kang selulose e tsoang ho limela tsa limela.
Mekhoa e Hlahang ea Kopo ea HEC ho Coatings:
Liqapi tse Sebeletsang Tikoloho:
Ka khatello e ntseng e eketseha ea melao ea ts'ebetso le ea tikoloho, ho na le tlhokahalo e ntseng e eketseha ea litlolo tsa litlolo tse sebelisang li-additives tse sebetsang hantle tse kang HEC. Bio-based HEC e nkiloeng mehloling e tsosolositsoeng e fana ka mokhoa o tsitsitseng oa li-polymers tse thehiloeng ho petroleum, ho fokotsa carbon footprint le phello ea tikoloho.
Li-Coatings tsa Ts'ebetso e Phahameng:
Tlhokahalo ea liphahlo tse nang le ts'ebetso e phahameng ka ho tšoarella ho phahameng, ho hanyetsa boemo ba leholimo, le thepa ea botle e tsamaisang ho amoheloa ha li-additives tse tsoetseng pele joalo ka HEC. Baetsi ba liforomo ba ntse ba hlahloba mekhoa e mecha ea ho ntlafatsa ts'ebetso ea liphahlo ba sebelisa libopeho tse thehiloeng ho HEC, ho fana ka lisebelisoa tse fapaneng ho tloha ho lipente tsa meralo ho isa ho liphahlo tsa likoloi.
Digital Coating Technologies:
Tsoelo-pele ea theknoloji ea ho roala ka dijithale, joalo ka khatiso ea inkjet le ho bapisa mebala ea dijithale, e fana ka menyetla e mecha ea ts'ebeliso ea HEC ka liphahlo. Lisebelisoa tse thehiloeng ho HEC li ka ntlafatsoa bakeng sa ho lumellana le mekhoa ea khatiso ea digital, e leng ho nolofalletsang taolo e nepahetseng holim'a thepa ea ho roala le ho ntlafatsa boleng ba khatiso le ho nepahala ha mebala.
Hydroxyethyl cellulose (HEC)e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea liphahlo ka ho sebetsa joalo ka motenya, mofetoleli oa rheology le oa pele oa filimi. Mehaho ea eona e ikhethang e thusa ho laola ka nepo viscosity, boemo bo holimo, ho hanyetsa le ho khomarela li-substrates. Likhatelo-pele tsa morao-rao tsa theknoloji ea HEC le mekhoa e hlahang ts'ebelisong ea eona li totobatsa bohlokoa ba eona e le tlatsetso e fapaneng mekhoeng ea liphahlo. Ha indasteri ea liphahlo e ntse e tsoela pele ho fetoha, HEC e ikemiselitse ho lula e le karolo ea bohlokoa ho nts'etsopele ea litharollo tsa boleng bo holimo, tse tšoarellang.
