1. Mehopolo ea mantlha
Hydroxethyl celdloulose (Hec): Hydroxeeyyl cellulosese (Hec) ke komporo ea polymer ea tlhaho, hangata e fumanoang ka phatla ea cellulose. Hydroxethyl (-ch2chhh Hec o sebelisoa haholo masimong a mangata a kang bosholu, litlolo, lijo, lijo le likhoebo tsa meriana.
Sesebelisoa sa Ethyl (EC): Ethyl cellulose (ECYL Ho fapana le hec, ethyl (-cl5) e kenngoa ka molek'huleng ea EC ho e-na le sehlopha sa hydroxeekl. E na le liahelo ebile e na le litsietsi 'me hangata e qhibiliha li-solvents tsa manyolo empa li sa khathatse ka metsing. EC e sebelisoa hangata indastering e kang merimaticas, ho ba masala, 'me ho na le mesebetsi e litšila le ho theha lifilimi.
2. Phapang ka sebopeho sa lik'hemik'hale le tharollo
Sebopeho sa lik'hemik'hale:
Sebopeho sa limolek'hule sa hec se thehoa ka ho tsamaisa limolek'hulele tsa celdoulose ka hydroxethyyl (Ch2ch2h) lihlopha tse nkang sebaka. Phetoho ena e etsa hore a hec hydrophilic mme e ka felisoa hantle metsing.
Sebakeng sa EC, lihlopha tsa Ethyl (C2H5) Nka nkela lihlopha tse ling tsa hydrouddy
Fulle:
Hec e botsoa habonolo metsing, haholo-holo ka metsing a futhumetseng, haholo metsing a futhumetseng, haholo metsi a futhumetseng, haholo a amana le boima ba limolek'hule le tekanyo ea hydroxethyyhy. Ka lebaka la alloubility ea bona, hangata hec e sebelisoa maemong ao ho hlokahala khahlanong le metsi a metsi, joalo ka bosholu, li-thimikeners, li-thickere
EC e na le litsie tse mpe ka metsing, empa e na le liliba tse ntle joalo ka li-solven le solnong ea kelome. Ka hona, ec hangata e sebelisoa libakeng tse nang le botsitso e le thipa kapa filimi ea pele.
3. Masimo a kopo
Kopo ea Hec:
Likotsi: Hec e sebelisoa e le Morifier ea thipa le Rheology bakeng sa likotlo tse thehiloeng metsing, tse ka ntlafatsang mofokoli, tse ka ntlafatsang phapo, e leng thepa ea ho emisoa le e thibelang likokoana-hloko.
Li-cosmetics: indastering ea litlolo, Hec e sebelisoa linyetleng tse kang li-loutions, li-shampoos le litlolo tsa letlalo, emulifier le mongoli.
Mefuta: Hec e boetse e sebelisoa ho litokisetso tsa lithethefatsi tse laoloang ke lithethefatsi joalo ka thipa le moemeli oa ho rata ho thusa lithethefatsi kapele.
Kaho: indastering ea kaho, hec e sebelisoa e le thickener bakeng sa samente kapa seretse ho ntlafatsa nako ea kaho le ho ntlafatsa ts'ebetso.
Kopo ea EC:
Meriana:
Likotsi le likhathatso: Ka indastering ea makhapetla, hangata e sebelisoa e le tlheketla le filimi ea pele. E ka eketsa botenya ba ho koata le ho ntlafatsa ho hanyetsa Melao ea Liphoto tsa Boemo
Lijo: EC e boetse e sebelisoa lebaleng la lijo, haholo-holo e le thipa ebile e boreleli, 'me e sebelisoa lijong tse kang jelly le pompong.
Li-cosmetics: EC e sebelisoa ka litlolo ho eketsa pono le botsitso ba emulsions, hape e ka sebelisoa e le motsoako oa letlalo.
4. Papiso ea ts'ebetso
Thickening:
Ka bobeli Hec le Ec ba na le litlamorao tse ntle tsa thiko, empa Hec o bonts'a ho tšosa ka metsing, haholo-holo ho ne ho loketse lits'ebetso tse senyehang. EC e bonts'a litlamorao tse ntle tse tona haholo ho li-solvents tsa manyolo ka lebaka la hydrophobicity ea eona.
SELUBLIT LE BOTSOALLE:
Hec o na le sokollo e ntle ea metsi le botsitso bo phahameng ba solo, kahoo e sebelisoa haholo lits'ebetsong tse aparetseng. EC e na le solubity e mpe ebile e sebelisoa haholo ka li-solvents kapa litsamaiso tse monate.
Rheology:
Matloana a lietsalohi tsa litlatsetso tsa hec a fapane haholo haholo ka meahong e fapaneng, hangata e bonts'a boitšoaro bo tloaelehileng ba mokelikeli. Hangata ec e na le litšehetso e lulang e le teng, haholo-holo li-solvents tsa khale.
Hydroxethyl cellulosese (Hec) le Ethyl cellulose (E E ngoe Metsi a aliti a Hec a qubu ea metsi le tse matlafatsang a ho sebelisoa haholo lits'ebetsong tse thehiloeng metsing, tse kang makhapetla, litlolo le meriana. EC e sebelisoa hangata lits'ebetsong tsa solvent e matla, joalo ka meriana, likhakanyo, likhakanyo, joalo ka ha lisolule le hydrophobicity. Khetho ea tse peli e lokela ho ikemisetsa ho latela litlhoko tse ikhethang tsa kopo le mofuta oa solvent.
