Hydroxye ethyl celdsese (Hec) ke sekhele le motlatsi oa Polymer, e bapalang karolo ea bohlokoa lits'ebetsong tse fapaneng lebaleng la lik'hemik'hale. Polymer ea metsi a metsi e ka har'a clumane, 'me cleloulose ke polymer ea tlhaho e fumanehang leboteng la semela. Kenyelletso ea sehlopha sa hydroyl se ka ntlafatsa eallo ea metsi le ho fetola thepa ea lik'hemik'hale ea selefounu.
1. Selelekela ho hydroxye ethyl (hec)
Hydroxye ether ke moqapi oa cellulose, 'me cloulose e ngotsoe ka polyer e nang le poone e hokahantsoeng ke bonngoe ba glucose thoko. Sehlopha sa hydroyl ho HOC se ile sa hlahisoa ke karabelo ka oxide. Phetoho ena e ntlafatsa eallo ea polymer ka metsing, 'me e fana ka litšobotsi tse ikhethang tsa ho fumana lisebelisoa tse fapaneng tsa ho fumana litsamaisong tse fapaneng tsa lik'hemik'hale tse fapaneng.
2. Sebopeho le litšobotsi tsa Hec
Sebopeho: Sehlopha sa hydroxyl se khomaretse sehlopha sa tombroyl sa ketane e ka sehloohong ea cellulose, e fanang ka meaho ea hec e sa sebetseng le e sa fetoheng. Tekanyo ea sebaka (DS) e emela palo ea lihlopha tsa hydroxyl ea yuniti e 'ngoe le e' ngoe ea glucose e ka bang le ho ama litšobotsi tsa polymer.
SELLE: Hec li ka qhibiliha habonolo metsing a batang a etsang tharollo e pepenoang le e bona. Matla a ancudity a angoa ke lintho tse kang mocheso, pH le ion matla.
Viscosity: e 'ngoe ea likarolo tsa bohlokoa tsa Hec ke bokhoni ba eona ba ho fetola pono ea tharollo. Sena se etsa hore e be ea bohlokoa indastering e laolang metsi a mangata.
3. Synthesis ea hydroxyl ethyl conllouloulose
Karabelo ea Ts'ebetso: Synthes ea HEC e kenyelletsa karabelo lipakeng tsa cellulose le oxide ha ho ba sieo ka li-alkaline catilysts. O ka laola degree ea sebaka ka ho fetola maemo a boits'oaro (joalo ka mocheso, nako le karabelo ea maikutlo).
Ho hloekisoa: Lihlahisoa tsa ho qetela hangata li hloekisoa ho tlosa litšila le reganation e sa rateheng ho netefatsa litšobotsi tse hlokahalang tsa Hec.
4. Kopo ea lik'hemik'hale
Ho penta le ho qoelisoa: Hec e sebelisoa haholo joalo ka pente ea metsi le likokoana-hloko. E ntlafatsa litšobotsi tsa kopo mme e ntlafatsa phallo ea pente.
Li-cosmetics le lihlahisoa tsa tlhokomelo ea motho ka mong:
PharmacEucal: Ho Pharmaticacal Fomatical, Hec e sebelisoa e le matlapilio, filimi le seriti sa phetisetso ea lithipa tsa lithethefatsi.
Liindasteri tsa kaho: Hec e sebelisoa bakeng sa thepa ea ho haha, e kang sistimi e beiloe seretse le ho itebisa.
5. Karolo e khomaretsoeng ka metsi
Foromo ea Puchin: Ho kenyelletsa Hec ho khomaretsong ea metsi e entsoeng ka metsi ho fana ka litšobotsi tse khomarelang tsa taolo ea liqhomane, botsitso le ntlafatso. Ho bohlokoa haholo ts'ebelisong e sa lokelang ea likhato tse thata-holo.
6. Ntlafatsa oli ea Ail
Viscostory Modiferity: E ntlafatsa pono ea metsi e sebelisoang ho enta, ka ho etsa joalo e khothaletsa ho fallisoa ha oli polokelong.
7. Ts'ireletso ea Tikoloho le ho tsitsa
Bio Draation: Hangata hec hangata e nkoang e le lijoana le ho thusa tikoloho ea eona. Leha ho le joalo, ho tšehetsa tlhahiso ea eona ka kakaretso ho latela lintlha tse kang celluloulose le ts'ebetso ea thepa.
8. Phephetso le maikutlo a kamoso
BioComphaetient: Leha hec e nkoa e sireletsehile, e ka bang litlamorao tsa ho bitsetsa likokoana-hloko tse ling likopo tse itseng, haholoholo lebaleng la bongaka le lithethefatsi, li ntse li etsa lipatlisiso tsa lipatlisiso.
Green o tebile: Boiteko bo tsoelang pele bo shebane le nts'etsopele ea tikoloho ea tikoloho ea Synnthesis e mosa ea Synnthesis e nang le tikoloho ea li-Synthesis tse nang le maikutlo a tlhahiso ea tlhahiso ea eona ea tikoloho ea tlhahiso ea eona.
Hydroxyeyl Contelulose e phetha karolo ea bohlokoa likopo tse fapaneng tsa lik'hemik'hale, e fana ka motsoako o ikhethang oa metsi, phetoho ea li-viscrosity le biodegradading le bioderadadadadadadadadadadadadadadad. Tšusumetso ea eona ea indasteri e kang pente, litlolo, meriana le pholiso le oli. Ka ho tsoela pele ho lipatlisiso, mofuta oa Sheba le ts'ebeliso ea oona ka oona masimong a hlasimollang a ka atoloha, ka ho 'na a tsoela pele ho ba bohlokoa.
Hydroxye ethyl cellulose e tiisang litlhoko tsa machaba a polytrity ea polytries, 'me phello ea eona e ntse e eketseha libakeng tse ngata tse itšetlehileng ka eona.
