Cellulose ethers| Phofo ea Polymer e ka qhaloang hape
Li-cellulose ethersle Redispersible Polymer Powder (RPP) ke lihlopha tse peli tse fapaneng tsa thepa, e 'ngoe le e' ngoe e na le thepa ea eona le lisebelisoa. Ha re hlahlobeng sehlopha ka seng:
Cellulose Ethers:
1. Tlhaloso:
- Li-cellulose ethers ke lelapa la li-polymers tse qhibilihang ka metsing tse nkiloeng ho cellulose, polima ea tlhaho e fumanehang maboteng a lisele tsa semela.
2. Mefuta:
- Mefuta e tloaelehileng ea li-cellulose ethers e kenyelletsa Methyl Cellulose (MC), Hydroxyethyl Cellulose (HEC), Hydroxypropyl Cellulose (HPC), le Hydroxypropyl Methylcellulose (HPMC).
3. Thepa:
- Ho qhibiliha ha metsi: Li-cellulose ethers hangata li qhibiliha metsing, li etsa li-gel tse bonaletsang.
- Viscosity: Ba ka fetola viscosity ea tharollo, ba etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng.
- Ho etsa lifilimi: Li-ether tse ngata tsa cellulose li na le thepa ea ho etsa lifilimi.
4. Likopo:
- Meriana ea Meriana: E sebelisoa e le li-binders, disintegrants, le lisebelisoa tsa ho roala filimi mefuteng ea matlapa.
- Kaho: Ho hiroa ka seretse, samente, le likhomaretsi tsa lithaele bakeng sa ho sebetsa hantle le ho khomarela.
- Indasteri ea Lijo: E sebelisoa e le li-thickeners le li-stabilizer lihlahisoa tse fapaneng tsa lijo.
- Lihlahisoa tsa Tlhokomelo ea Motho: E fumanoa ka litlolo, litlolo, le li-shampoo bakeng sa thepa ea tsona e teteaneng le ho tsitsisa.
Powder ea Polymer e Hahang hape (RPP):
1. Tlhaloso:
- Redispersible Polymer Powder ke phofo e phallang e sa lefelloeng, e tšoeu e nang le sekontiri sa polymer se kopantsoeng le li-additives le li-filler.
2. Sebopeho:
- Ka tloaelo e entsoe ka li-emulsion tsa polymer (joalo ka vinyl acetate-ethylene copolymers) tse omisitsoeng ho etsa phofo.
3. Thepa:
- Redispersibility ea Metsi: RPP e ka boela ea qhalakana ka metsing ho etsa filimi, e tšoanang le emulsion ea pele ea polymer.
- Adhesion: E fana ka sekhomaretsi le bonolo ho lirekere, samente le lisebelisoa tse ling tsa kaho.
- Tlhahiso ea Filimi: E ka etsa filimi e momahaneng le e tenyetsehang ha e omisoa.
4. Likopo:
- Indasteri ea Kaho: E sebelisoa ho likhomaretsi tsa lithaele, liphetolelo tse thehiloeng ho samente, le metsoako ea ho ikemela ho ntlafatsa ho khomarela, ho tenyetseha le ho thibela metsi.
- Li-Mortars le Renders: E ntlafatsa thepa e kang ho sebetsa, ho tšoarella, le ho khomarela.
- Lipente le Liaparo: E ka sebelisoa lipenteng tsa meralo le liphahlo bakeng sa ho fetoha habonolo le ho khomarela.
Likhethollo:
- Sollubility:
- Li-cellulose ethers hangata li qhibiliha ka metsing.
- RPP ha e qhibilihe ka metsing empa e ka boela ea hasana ka metsing ho etsa filimi.
- Libaka tsa Kopo:
- Li-cellulose ethers li na le ts'ebeliso e fapaneng litlhare, lijong le tlhokomelong ea motho ka mong, ntle le kaho.
- RPP e sebelisoa haholo indastering ea kaho bakeng sa ho ntlafatsa thepa ea seretse, samente le liphahlo.
- Sebopeho sa Lik'hemik'hale:
- Li-cellulose ethers li tsoa ho cellulose, polima ea tlhaho.
- RPP e entsoe ka li-emulsion tsa maiketsetso tsa polymer.
Ka kakaretso, le hoja li-cellulose ethers e le li-polymers tse qhibilihang ka metsing tse nang le mefuta e sa tšoaneng ea lisebelisoa, Redispersible Polymer Powder ke phofo e sa qhibiliheng ka metsing e sebelisoang haholo-holo indastering ea kaho ho ntlafatsa thepa ea thepa ea kaho. Li sebeletsa merero e fapaneng 'me li khethoa ho latela litlhoko tse khethehileng tsa kopo.
