Cellulose Ether (HPMC,MC,HEC,EC,HPC,CMC,PAC)

Li-cellulose ethers ke sehlopha sa li-polymers tse qhibilihang ka metsing tse tsoang ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela. Li sebelisoa haholo liindastering tse fapaneng bakeng sa ho tiisa, ho tsitsisa, ho etsa lifilimi le thepa ea ho boloka metsi. Mona ke kakaretso ea mefuta e meng e tloaelehileng ea cellulose ethers:

1. Hydroxypropyl Methylcellulose (HPMC): HPMC ke ether ea selulose e sebetsang ka mefuta e mengata e sebelisoang haholo meahong, litlhare, tlhokomelong ea motho, le indastering ea lijo. E tsebahala ka ho boloka metsi hantle, ho tenya, le ho etsa lifilimi. HPMC e atisa ho sebelisoa e le motenya, binder, le rheology modifier ka seretse, sekgomaretsi sa lithaele, matlapa a meriana, litlolo, le lihlahisoa tsa lijo.
2. Methylcellulose (MC): MC e tšoana le HPMC empa e na le tekanyo e tlaase ea ho kenya sebaka sa lihlopha tsa methyl. E sebelisoa lits'ebetsong moo ho bolokoang metsi a tlase le viscosity e hlokahalang, joalo ka litlhare tsa meriana, litharollo tsa mahlo, le joalo ka motenya oa lihlahisoa tsa lijo.
3. Hydroxyethyl Cellulose (HEC): HEC ke ether e 'ngoe e sebelisoang haholo ea cellulose e tsejoang ka ho boloka metsi hantle le thepa ea eona e teteaneng. Hangata e sebelisoa linthong tsa kaho tse kang lipente, lirafa le likhomaretsi, hammoho le lihlahisoa tsa tlhokomelo ea motho tse kang li-shampoo, litlolo le litlolo.
4. Ethyl Cellulose (EC): EC ke cellulose ether e fetotsoeng ka lihlopha tsa ethyl. Haholo-holo e sebelisoa litlhare, litlolo, le lits'ebetso tse ikhethang moo thepa ea eona ea ho etsa lifilimi, litšitiso le tokollo ea nako e telele e leng molemo. Hangata EC e sebelisoa e le thepa ea ho roala bakeng sa matlapa le li-pellets mefuteng ea meriana.
5. Hydroxypropyl Cellulose (HPC): HPC ke cellulose ether e fetotsoeng ka lihlopha tsa hydroxypropyl. Hangata e sebelisoa e le sekontiri se teteaneng, se tlamang, le sa ho etsa lifilimi ho tsa meriana, lihlahisoa tsa tlhokomelo ea botho, le lisebelisoa tsa lijo. HPC e fana ka solubility e babatsehang, taolo ea viscosity, le botsitso litharollong tsa metsi.
6. Carboxymethyl Cellulose (CMC): CMC ke cellulose ether e qhibilihang ka metsing e nkiloeng ho selulose ka carboxymethylation. E sebelisoa haholo joalo ka setei, se tsitsitseng, le se tlamang lihlahisoa tsa lijo, meriana, lihlahisoa tsa tlhokomelo ea motho, le lits'ebetso tsa indasteri. CMC e etsa litharollo tse hlakileng, tse nang le li-viscous 'me hangata e sebelisoa e le ntho e tiisang li-sauces, liaparo, le ho emisoa ka molomo.
7. Polyanionic Cellulose (PAC): PAC ke cellulose ether e fetotsoeng ka lihlopha tsa anionic, hangata lihlopha tsa carboxymethyl kapa phosphonate. Haholo-holo e sebelisoa e le tlatsetso ea taolo ea tahlehelo ea mokelikeli marong a ho cheka bakeng sa tlhahlobo ea oli le khase. PAC e thusa ho fokotsa tahlehelo ea mokelikeli, ho ntlafatsa viscosity, le ho tsitsisa seretse sa ho cheka tlas'a maemo a phahameng a mocheso le khatello e phahameng.

Li-cellulose ethers tsena li fana ka mefuta e mengata ea ts'ebetso le lits'ebetso ho pholletsa le liindasteri tse fapaneng, tse tlatsetsang ts'ebetsong, botsitso, le boleng ba lihlahisoa tse ngata le litlhophiso.
