Hydroxethyl celdloulose (Hec) le hydroxyproppyl celluulose (HPC) ka bobeli ke li-derivamatives tsa cellulose, polymer ea tlhaho e fumanehang marakong a limela. Lipehelo tsena li sebelisoa haholo indastering e fapaneng ka lebaka la thepa ea tsona e ikhethang. Le hoja ho na le mabitso a tšoanang le a khemisi ea lik'hemik'hale, ho na le liphapang tse ngata lipakeng tsa Hec le HpC ho ea ka thepa ea bona, likopo le ts'ebeliso.
Sebopeho sa lik'hemik'hale:
Hec le hpc ke li-soricolese tse fetotsoeng ka lihlopha tsa hydroxyalchl. Lihlopha tsena li kopantsoe le sekhutlo sa mokokotlo oa cellulose ka likhokahano tsa ethersages, tse bakoang ke lisosa tse ntlafalitsoeng le thepa e meng e lakatsehang.
Hydroxeeyl cellulolose (Hec):
Libakeng tsa Hydroykyethy (-ch2chhhhhh
Degree of Aptulution (DS) e bua ka palo e tloaelehileng ea lihlopha tsa hydroyethyl ka yuniti ea arhydroglucose. Litokoloho tse phahameng tsa DS li bonts'a karolo e phahameng ea ho nkeloa sebaka se phahameng, e bakoang kenyelletso e eketsehileng le thepa e 'ngoe e fetotsoeng.
Hydroxypropypropyl conlulose (HPC):
Ho HPC, Lihlopheng tsa Hydroxypropyl (-ch2Chohch3) li khomaretsoe likarolo tsa anghydroglucose morao.
E ts'oanang le hec, tekanyo ea sebaka (DS) ho HPC e khetholla thepa ea eona. Litsebi tsa DOS tse phahameng tsa DS li fella ka linyeoe tse eketsehang le thepa e fetotsoeng.
LITLHAKISO TSA 'MELAO:
Hec le HPC ba na le thepa e tšoanang ea 'mele ka lebaka la cellulose ba tloaelehileng ba khutla. Leha ho le joalo, phapang e poteletseng e hlaha ho tsoa ho lihlopha tse tobileng tsa li-alkyl tse hokahantsoeng le litloholo tsa selefounu.
Fulle:
Ka bobeli Hec le HPC li qhibiliha ka metsing le li-solvents tsa manyolo, ho latela tekanyo ea bona ea sebaka. Litokoloho tse phahameng tsa DS ka kakaretso li fella ka li-scoudity tse ntle.
Hec o batla ho bonts'a linyeoe tse ntle ka metsing ha li bapisoa le HPC, haholo-holo mochesong oa hydrophilic oa li-hydrophilic.
Viscosity:
Ka bobeli Hec le HPC ba khona ho theha tharollo ea li-viscous ha ba qhibiliha ka metsing. Lino tse mabapi le tharollo li itšetlehile ka lintho tse kang polymmet le boemo bo botle ba naha, le mocheso.
HPC Tharollo e bonts'a liketsahalo tse phahameng ho feta tharollo ea hec
Likopo:
Hec le HPC ba sebelisa haholo indastering e fapaneng, ho kopanyelletsa le liphatlalatso, lihlahisoa tsa tlhokomelo, lijo, bosholu le sebopeho sa bona se ikhethileng le boits'oaro ba bona bo ikhethileng.
Merima:
Ka bobeli Hec le HPC ba sebelisoa hangata e le li-pharmacticotic ka mefuta ea lithethefatsi. Ba sebetsa e le mahlahahlaha, ba tsitlellang, barekisi ba filimi le moloko oa lifoto oa lipono, le ha o happhllhame.
HPC, ka thepa ea eona e phahameng ea litšoantšo le thepa e etsang lifilimi, hangata e khethoa ka mekhabiso e lokollotsoeng le litafole tsa molomo.
Hc e sebelisoa hangata litokisetso tsa mahlo tse ngata ka lebaka la thepa ea eona e ntle ka lebaka la mohoebi le ho lumellana le lisele tse tsoang botebong ba pelo.
Lihlahisoa tsa tlhokomelo ea motho:
Li-cosmetics le lihlahisoa tsa tlhokomelo ea motho, bao ka bobeli ba Hec le HPC ba sebelisoa e le mahlahahlaha le litlolo tsa filimi, litlolo, litlolo le litlolo.
Hec o khethoa lihlahisoa tsa tlhokomelo ea moriri ka lebaka la maemo a eona a boemo bo botle ba boemo ba eona ba boemo ba boemo bo botle ba bona
HPC e sebelisoa hangata lihlahisoa tsa tlhokomelo ea molomo, tse kang leino le melomo, ka lebaka la thepa ea eona e tobatsang le e thetsang.
Indasteri ea lijo:
Hec le hpc ba amohela lits'ebetso tsa lijo ka lits'ebetso joalo ka lits'ebetso joalo ka li-athiniliz, ba hlohlelletsa le basumuriers lihlahisoa tsa lijo.
Hangata li sebelisoa lihlahisoa tsa lebese, lisake, liaparo le lijo tsa tsoekere ho ntlafatsa teetso, molomo, le bongoana.
Hec o ne a rata mefuta ea lijo tsa acid ea acid ka lebaka la botsitso ba eona holim'a kholo ea ph.
Bokotuli le lisebelisoa tsa kaho:
Ka har'a lits'oants'o le lisebelisoa tsa kaho, Hec le HPC li sebelisoa e le basebeletsi ba tsietsi, Rheology Madifiers le baetsi ba likamano tsa botona le botšehali ba lidola, ba thetsang.
Hec o khethoa ho li-pente ea morao-rao ea pente ka lebaka la boitšoaro ba eona bo bobe le ho tsamaisana le ho tsamaisana le litlatsetso tse ling tsa pente.
HPC e sebelisoa hangata lisebelisoa tse thehiloeng ho tumello ea ho ntlafatsa ho ntlafatsa, hodhesion le ho boloka metsi.
Hydroxethyl cellulosese (Hec) le hydroxyproppyl celluulose (HPC) ke li-celluloses tsa celluulose ka thepa le lits'ebetso tse ikhethileng. Ha bobeli ba lipolao ba tšoanela ho tšoana le sebopeho sa bona sa lik'hemik'hale le thepa ea 'mele, ho fapana le lihlopha tse khethehileng tsa hydroxyl ba khokhothetsoeng ho sejo se khethehileng sa hydrone. Liphapang tsena li fella ka mefuta ena, Viscosity lits'ebetsong tse fapaneng ho tloha lisamaneng, lihlahisoa tsa tlhokomelo le lisebelisoa tsa kaho. Ho utloisisa liphapang tsena ho bohlokoa bakeng sa ho khetha ts'ebetso e nepahetseng ea khetla ea Cellulose bakeng sa lits'ebetso tse ikhethang, e bonts'a ts'ebetso e nepahetseng le ts'ebetso ea ts'ebetso.
