Izinkinga zakudala ngeHydroxypropyl Methyl Cellulose
1. Iyini ukusetshenziswa okuyinhloko kwe-hydroxypropyl methylcellulose (HPMC)?I-HPMC isetshenziswa kabanzi ezintweni zokwakha, ezinengilazi, izinsalela zokwenziwa, izitsha zobumba, imithi, ukudla, izindwangu, ezolimo, izimonyo, ugwayi nezinye izimboni.I-HPMC ingahlukaniswa ngebanga lokwakha, ibanga lokudla ne...Funda kabanzi -
Uyini umehluko phakathi kwe-HPMC ne-MC
I-MC i-methyl cellulose, etholakala ngokwelapha ukotini ocolisisiwe nge-alkali, kusetshenziswa i-methyl chloride njenge-ejenti ye-etherifying, nokwenza i-cellulose ether ngochungechunge lokusabela.Ngokuvamile, izinga lokushintsha liyi-1.6 ~ 2.0, futhi ukuncibilika kubuye kuhluke ngamadigri ahlukene ...Funda kabanzi -
Izinto Ezithinta Ukukhiqizwa Kwe-Viscosity ye-HPMC
1. I-Viscosity Control I-High-viscosity hydroxypropyl methylcellulose ayikwazi ukukhiqiza i-cellulose ephezulu kakhulu kuphela ngokuyicofa bese ifaka i-nitrogen.Kodwa-ke, uma ithuluzi lokulinganisa i-oxygen lingafakwa kuketela, ukukhiqizwa kwe-viscosity kungalawulwa ngokuzenzakalelayo.2. Ukusetshenziswa kwe...Funda kabanzi -
Isifundo sobuchwepheshe bokuqinisa upende osuselwe emanzini omfushane kakhulu
1. Incazelo kanye nomsebenzi we-thickener Additives ezingakhulisa kakhulu i-viscosity yamapende asekelwe emanzini abizwa ngokuthi ama-thickeners.Ama-thickeners adlala indima ebalulekile ekukhiqizeni, ekugcinweni nasekwakheni ama-coatings.Umsebenzi oyinhloko we-thickener ukwandisa i-viscosity o ...Funda kabanzi -
Mayelana ne-Hydroxypropyl Methyl Cellulose
1. Kuyini ukusetshenziswa okuyinhloko kwe-cellulose?I-HPMC isetshenziswa kabanzi ezintweni zokwakha, ezinengilazi, izinsalela zokwenziwa, izitsha zobumba, imithi, ukudla, izindwangu, ezolimo, izimonyo, ugwayi nezinye izimboni.I-HPMC ingahlukaniswa ngebanga lezimboni, ibanga lokudla kanye nebanga lezemithi ngokusho ...Funda kabanzi -
Isicelo se-HPMC ezintweni zokwakha
IHydroxypropyl methylcellulose (HPMC) iyi-ether engeyona ionic cellulose eyenziwe nge-cellulose yezinto ze-polymer yemvelo ngochungechunge lokucutshungulwa kwamakhemikhali.Ziyimpushana emhlophe engenaphunga, engenabuthi futhi engenabuthi evuvukala emanzini abandayo ibe isixazululo se-colloidal esicacile noma esilufifi kancane.Unochwepheshe...Funda kabanzi -
Ukuhlukaniswa kwe-HPMC nendlela yokuqedwa
1.Ukuhlelwa: I-HPMC ingahlukaniswa ngohlobo olusheshayo kanye nohlobo lwe-hot-melt.Imikhiqizo yohlobo olusheshayo ihlakazeka ngokushesha emanzini abandayo bese inyamalala emanzini.Ngalesi sikhathi, uketshezi alunayo i-viscosity, ngoba i-HPMC ihlakazekile kuphela emanzini futhi ayinakho ukuchithwa kwangempela.Ngemva kwemizuzu emi-2, i-...Funda kabanzi -
Ukusetshenziswa okuyinhloko kanye nomehluko we-HPMC HEC 01. I-Hydroxyethyl Cellulose
01. I-Hydroxyethyl Cellulose Njenge-surfactant engeyona i-ionic, i-hydroxyethyl cellulose ayinayo kuphela imisebenzi yokumisa, ukuqina, ukuhlakaza, ukuntanta, ukubopha, ukwenza ifilimu, ukugcinwa kwamanzi kanye nokuhlinzeka nge-colloid evikelayo, kodwa futhi inezindawo ezilandelayo: 1. HEC iyancibilika ekushiseni noma c...Funda kabanzi -
Iyiphi impahla eluhlaza eyinhloko ye-hydroxypropyl methylcellulose
Impahla eluhlaza eyinhloko ye-HPMC ifana ne-bellow: ukotini ocwengekile, i-methyl chloride, i-propylene oxide, ezinye izinto zokusetshenziswa, i-caustic soda, i-asidi, i-toluene, i-isopropanol, njll. Uyini umphumela oyinhloko we-hydroxypropyl methylcellulose ku-putty powder, nokuthi ngabe i-organic chemistry kwenzeka?I-HPMC idlala imisebenzi emithathu...Funda kabanzi -
Ukuhlangana Kwe-Hydroxyethyl Cellulose kanye Nezingubo Ezisekelwe Emanzini
Iyini i-hydroxyethyl cellulose?I-Hydroxyethyl cellulose (HEC), okuphuzi okumhlophe noma okuphaphathekile, okunganuki, okuqinile okune-fibrous okungewona ubuthi noma okuyimpuphu, okulungiselelwe ukufakwa kwe-etherification ye-alkaline cellulose ne-ethylene oxide (noma i-chlorohydrin), eyingxenye yohlobo lwe-Nonionic soluble cellulose ethers.Ngoba i-HEC inhle...Funda kabanzi -
