Kenyelletso ea Sehlahisoa sa Hydroxyethyl Methyl Cellulose HEMC

Hydroxyethyl Methyl Cellulose (HEMC)e eme e le karolo ea bohlokoa liindastering tsa sejoale-joale, e fetolang lits'ebetso le lihlahisoa ho pholletsa le mefuta e mengata ea ts'ebeliso. Ka thepa ea eona e ikhethang le mesebetsi e fapaneng e fapaneng, HEMC e fetohile sesebelisoa sa bohlokoahali ho tsa kaho, meriana, litlolo, le tse ling.

Sebopeho le Maemo:
HEMC, e nkiloeng ho selulose, e entsoe ka karabelo ea alkali cellulose ka methyl chloride le ethylene oxide. Sena se fella ka motsoako o nang le sehlopha sa methyl le sehlopha sa hydroxyethyl se kopantsoeng le likarolo tsa anhydroglucose tsa selulose. Tekanyo ea substitution (DS) ea HEMC, e laetsoeng ke karolelano ea molar ea lihlopha tse emeng ho li-unit tsa tsoekere, e laola thepa le ts'ebeliso ea eona.

E 'ngoe ea litšoaneleho tsa bohlokoa tsa HEMC ke ho qhibiliha ha eona ha metsi, e leng ho ntlafatsang ts'ebeliso ea eona lits'ebetsong tse ngata tsa metsi. E bonts'a thepa e ntle haholo ea ho tenya, ea ho etsa lifilimi, le e tlamang, e e etsa khetho e ratoang liindastering tse hlokang taolo ea rheological le botsitso. Ho feta moo, HEMC e na le boits'oaro ba pseudoplastic, bo e etsa hore e be mosesaane, ka hona e nolofalletsa ts'ebeliso le ho hasana habonolo.

Lisebelisoa:

Indasteri ea Kaho:
HEMC e bapala karolo ea bohlokoa lekaleng la kaho, haholo-holo e le tlatsetso ea hydrophilic polymer thepa e thehiloeng ho samente. Bokhoni ba eona bo makatsang ba ho boloka metsi bo netefatsa ho sebetsa ha seretse le konkreite ka nako e telele, ho fokotsa litaba tse kang ho omisa pele ho nako le ho peperana. Ho feta moo, HEMC e ntlafatsa momahano le momahano, e tlatsetsang ho matla le ho tšoarella ha thepa ea kaho.

Lefapha la Meriana:
Litlhahlobong tsa meriana, HEMC e sebetsa e le mothusi ea sebetsang ka mefuta-futa ka lebaka la ho lumellana ha eona le lintho tse phelang, ho se chefo, le tlhaho ea inert. E fumana ts'ebeliso e pharaletseng lits'ebetsong tsa phepelo ea lithethefatsi tse laoloang, moo e sebetsang joalo ka matrix ea pele, e ts'ehetsang tokollo ea lithethefatsi ka nako e telele. Ho feta moo, HEMC e sebetsa e le mofetoleli oa viscosity mekhoeng ea lihlooho, e matlafatsang botsitso ba sehlahisoa le ho tsitsisa.

Litlolo le Lihlahisoa tsa Tlhokomelo ea Motho:
HEMC e hlahella haholo ha ho etsoa litlolo le lihlahisoa tsa tlhokomelo ea motho ka lebaka la thepa ea eona ea ho etsa lifilimi le ho tenya. E sebetsa e le stabilizer ho li-emulsions, ho thibela ho arohana ha mekhahlelo le ho fana ka mokhoa o lakatsehang ho litlolo le litlolo. Ho feta moo, HEMC e sebetsa e le moemeli ea emisang li-shampoo le ho hlatsoa 'mele, ho netefatsa hore ho ajoa ka mokhoa o ts'oanang oa likaroloana tse emisitsoeng.

Lipente le Liaparo:
Ka indasteri ea lipente le liphahlo, HEMC e sebetsa e le tlatsetso e mengata, ho ntlafatsa viscosity, sag resistance, le color consistency. Bokhoni ba eona bo matla bo thusa ho emisoa ha li-pigments le li-filler, ho thibela ho tsitsa nakong ea polokelo le ts'ebeliso. Ho feta moo, HEMC e fana ka thepa e ntle ea boemo bo holimo ho liphahlo, e fellang ka hore ho be le liphetho tse boreleli le tse ts'oanang.

Melemo:

Kamohelo ea HEMC e fana ka melemo e mengata ho pholletsa le liindasteri tse fapaneng:
Matla a Ntlafetseng a ho sebetsa: HEMC e netefatsa hore thepa ea kaho e sebetsa ka nako e telele, e nolofatsa ts'ebetso le ho ntlafatsa tlhahiso ka kakaretso.
Ts'ebetso e Ntlafetseng ea Sehlahisoa: Litlhare le litlolo, HEMC e ntlafatsa botsitso ba tlhahiso, ho tsitsisa le ho sebetsa hantle, ho fella ka ts'ebetso e phahameng ea sehlahisoa.
Katleho ea Litšenyehelo: Ka ho ntlafatsa thepa ea rheological le ho fokotsa tšenyo ea thepa, HEMC e thusa ho tsamaisa mekhoa ea tlhahiso, e lebisang ho bolokeng litšenyehelo.
Tikoloho e tsitsitseng: HEMC, e nkiloeng mehloling ea selulose e tsosolositsoeng, e lumellana le lipakane tsa ts'ebetso, e fana ka mekhoa e meng ea eco-friendly ho li-additives tse tloaelehileng.
Ho feto-fetoha ha maemo: Ka lits'ebetso tsa eona tse pharalletseng le thepa e feto-fetohang, HEMC e fana ka litlhoko tse fapaneng tsa indasteri, e fana ka litharollo tse fapaneng bakeng sa mathata a fapaneng.

Hydroxyethyl Methyl Cellulose (HEMC) e eme e le lejoe la sekhutlo liindasteri tsa sejoale-joale, e bonts'a boqapi, ho feto-fetoha ha maemo le ho ts'epahala. Mehaho ea eona e ikhethang le mesebetsi e fapaneng e fetotse mekhoa le lihlahisoa ho pholletsa le kaho, meriana, litlolo le ho feta. Ha liindasteri li ntse li tsoela pele ho fetoha, HEMC e ntse e le malala a laotsoe ho ntšetsa pele tsoelopele, ho tlisa mehla e mecha ea ts'ebetso, ts'ebetso, le bokhabane.
