Cellulose Ethers

Cellulose Ethers ke Eng?

Li-cellulose etherske li-polymers tse qhibilihang ka metsing tse nkiloeng ho cellulose, polysaccharide ea tlhaho e fumanehang maboteng a lisele tsa limela. Li hlahisoa ke cellulose e fetolang lik'hemik'hale ka etherification, ho nkela lihlopha tsa hydroxyl (-OH) sebaka ka lihlopha tsa ether (-OR). Phetoho ena e ntlafatsa ho qhibiliha, botsitso ba mocheso, le thepa ea ho etsa filimi ea selulose, e leng se etsang hore e tšoanelehe bakeng sa mekhoa e mengata ea liindasteri le ea khoebo.

Mefuta ea Cellulose Ethers

Mefuta e atileng haholo ea li-cellulose ethers e kenyelletsa:

1. Methyl Hydroxyethyl cellulose(MHEC)

   • E nkiloe ka ho arabela selulose ka methyl chloride.

   • E qhibiliha ka metsing a batang empa eseng metsing a chesang.

   • E sebelisoa kahong, lijong, meriana.

2. Hydroxypropyl methylcellulose(HPMC)

   • E fetotsoe ka lihlopha tsa methyl le hydroxypropyl.

   • E sebelisoa haholo lisebelisoa tsa kaho, meriana (e le li-tablet binders), le lijo.

3. Hydroxyethyl Cellulose(HEC)

   • E entsoe ka ethylene oxide.

   • E sebelisoa lipente, litlolo, le lihlahisoa tsa tlhokomelo ea botho.

4. Carboxymethyl cellulose(CMC)

   • E entsoe ka chloroacetic acid.

   • E qhibiliha haholo ka metsi 'me e sebelisoa lijong, li-detergents le meriana.

5. Ethyl Cellulose (EC)

   • E fetotsoe ka lihlopha tsa ethyl.

   • Ha e qhibilihe ka metsing, ha e qhibilihe ka har'a metsoako ea tlhaho.

   • E sebelisoa ka ho roala, ho lokolloa ha lithethefatsi tse laoloang, le polasetiki.

Cellulose Ether e sebelisetsoa eng?

Li-cellulose ethers li sebeletsa merero e fapaneng liindastering tse ngata:

• Indasteri ea Kaho

  • E le lisebelisoa tse teteaneng le ho boloka metsi li thusa ho samente, seretse, samente le likhomaretsi tsa lithaele.

• Meriana ea meriana

  • E sebelisoa e le li-excipient ho meetso ea matlapa, li-coating agents, le li-matrices tse laoloang.

• Indasteri ea Lijo

  • E sebetsa joalo ka li-emulsifiers, stabilizers le thickeners lihlahisoa tse kang ice cream, lisoso le thepa ea ho baka.

• Litlolo & Tlhokomelo ea Motho

  • Fana ka botsitso le ho boloka mongobo ka litlolo, litlolo le li-shampoo.

• Lipente le Liaparo

  • Ntlafatsa viscosity, phallo, le sebopeho sa lifilimi.

• Lisebelisoa le Lisebelisoa

  • Sebetsa joalo ka li-stabilizers le li-ajenti tse teteaneng.

Cellulose Ethers Lefapheng la Lijo

Ts'ebetsong ea lijo, li-cellulose ethers li bapala karolo ea bohlokoa ka lebaka la tlhaho ea tsona e se nang chefo:

• Mokhoa oa ho ntlafatsa sebopeho: E fana ka sebopeho ho lihlahisoa tse se nang mafura a tlase kapa tse se nang gluten.

• Setsibotsi: E boloka ho tsitsisa le ho thibela karohano ea mekhahlelo ka li-sauces le liaparo.

• Thickening Agent: E fana ka viscosity e lakatsehang ka lino, sopho le lijo tse theolelang.

• Mofetoleli oa Mafura: E sebelisoa lijong tse nang le mafura a fokotsehileng bakeng sa molomo le sebopeho.

Li-ethers tse tloaelehileng tsa selulose tsa lijo li kenyelletsaHPMC, MC, leCMC. Tsena li amohetsoe ke FDA le EFSA bakeng sa tšebeliso ea chelete e laoloang.

Na Cellulose Gel Vegan?

Ee,gel ea cellulose ke vegan.
E tsoa mehloling ea limela tse kang makhasi a lehong kapa lithara tsa k'hothone. Ts'ebetso ha e kenyelle lihlahisoa tsa liphoofolo kapa lihlahisoa, ho etsa hore e tšoanelehe bakeng sa lijo tsa nama le tsa meroho. Hangata e sebelisoa e le mokhoa o mong oa vegan ho gelatin lihlahisoa tsa lijo.

Mokhoa oa ho etsa Cellulose Ether

Ho hlahisa li-cellulose ethers ho kenyelletsa mehato e mengata ea ho sebetsana le lik'hemik'hale:

1. Alkalization:

   • Selulose ea tlhaho e tšoaroa ka sodium hydroxide ho etsa alkali cellulose.

2. Etherification:

   • Alkali cellulose e sebetsana le etherifying agent e kang methyl chloride, ethylene oxide, kapa propylene oxide, ho itšetlehile ka sehlahisoa se lakatsehang.

3. Tlhoekiso:

   • Sehlahisoa ha se sebelisoe, se hlatsuoa le ho omisoa ho tlosa litšila, matsoai le lihlahisoa tse ling.

4. Milling & Classification:

   • Ether e omisitsoeng ea cellulose e siloa hore e be phofo e ntle 'me e arotsoe ka boholo ba likaroloana bakeng sa lisebelisoa tse fapaneng.

Ts'ebetso ena e etsoa tlas'a maemo a laoloang ho netefatsa polokeho le botsitso, haholo-holo bakeng sa lijo le litekanyetso tsa meriana.

Baetsi ba Cellulose Ethers

Baetsi ba bang ba hlahelletseng lefatšeng ka bophara ba cellulose ethers ba kenyelletsa:

• Ashland(USA)

• Khamphani ea Dow Chemical(USA)

• Likhamphani tsa Shin-Etsu Chemical Co.(Japane)

• Lotte Fine Chemical(Korea Boroa)

• Lamberti S.p.A(Italy)

• Litlhaloso tsa likarolo tsa Kima Chemical Co., Ltd.(Chaena)

• AkzoNobel (Nouryon)(Netherlands)

Likhamphani tsena li hlahisa mefuta e mengata e fapaneng ea lihlahisoa tsa ether ea cellulose bakeng sa lits'ebetso tsa indasteri, tsa meriana le tsa lijo.
