Ama-cellulose ether asetshenziswa kakhulu ahlanganisa i-HEC, i-HPMC, i-CMC, i-PAC, i-MHEC, njll. I-Nonionic water-soluble cellulose ether inokuhlangana, ukuqina kokuhlakazeka kanye namandla okugcina amanzi, futhi iyisengezo esiwusizo sezinto zokwakha.I-HPMC, i-MC noma i-EHEC isetshenziswa ezakhiweni eziningi ezisekelwe kusimende noma ze-gypsum, ezifana nodaka lwamatshe, udaka lukasimende, ukunamathela kukasimende, igypsum, ingxube kasimende ne-milky putty, njll., engathuthukisa ukuhlakazwa kukasimende noma isihlabathi kanye ngcono kakhulu i-Adhesion, ebaluleke kakhulu ku-plaster, usimende we-tile kanye ne-putty.I-HEC isetshenziselwa usimende, hhayi nje njenge-retarder, kodwa futhi njenge-ejenti yokugcina amanzi, futhi i-HEHPC nayo isetshenziswa kulokhu.I-MC noma i-HEC ivame ukusetshenziswa kanye ne-CMC njengengxenye eqinile yesithombe sangemuva.I-Medium-viscosity noma i-high-viscosity cellulose ethers ivame ukusetshenziswa ezintweni zokwakha ezinamathiselwe iphepha lodonga.
I-Hydroxypropyl methylcelluloseI-HPMCngokuvamile isetshenziselwa ukukhiqizwa kwe-putty powder yangaphakathi nengaphandle ene-viscosity ye-cellulose engu-100,000, odakeni lwempushana owomile, udaka lwe-diatom neminye imikhiqizo yempahla yokwakha, i-cellulose ene-viscosity ye-200,000 ivame ukusetshenziswa, futhi ekuzilinganiseni nokunye. izinsimbi ezikhethekile, i-cellulose ene-viscosity ye-400 ivame ukusetshenziswa.I-Viscosity cellulose, lo mkhiqizo unomphumela omuhle wokugcina amanzi, umphumela omuhle wokuqina kanye nekhwalithi ezinzile.I-HPMC isetshenziswa kabanzi embonini yezinto zokwakha futhi isetshenziswa ngenani elikhulu.I-Cellulose ingasetshenziswa njenge-retarder, i-ejenti yokugcina amanzi, i-thickener kanye ne-binder.I-Cellulose ether idlala indima ebalulekile odakeni olujwayelekile oluxutshwe okomile, udaka lwangaphandle olufakwa odongeni, udaka oluzilinganisa, ingcina yempushana eyomile, udaka oluhlanganisa uthayela, impushana eyimpuphu, i-putty yodonga lwangaphakathi nangaphandle, udaka olungangeni manzi, amalunga ongqimba oluncane, njll. , banethonya elibalulekile ekugcineni amanzi, isidingo samanzi, ukuqina, ukuncipha kanye nokusebenza kwesistimu ye-stucco.
Imikhiqizo ye-Hydroxypropyl methylcellulose HPMC ihlanganisa izici eziningi ezibonakalayo namakhemikhali ukuze ibe umkhiqizo oyingqayizivele onokusetshenziswa okuningi.Izakhiwo ezihlukahlukene zimi kanje:
◆ Ukugcinwa kwamanzi: Kungagcina umswakama ezindaweni ezinezimbotshana ezifana namabhodi osimende odongeni nezitini.
◆Ukwenza ifilimu: Ingakha ifilimu esobala, eqinile futhi ethambile enokumelana nowoyela okuhle kakhulu.
◆I-Organic Solubility: Umkhiqizo uyancibilika kwezinye izincibilikisi zemvelo, njenge-ethanol/amanzi, i-propanol/amanzi, i-dichloroethane kanye nesistimu yezincibilikisi ezakhiwe ngezincibilikizi ezimbili eziphilayo.
◆I-Gelation eshisayo: Isixazululo esinamanzi somkhiqizo sizokwakha ijeli lapho sishiswa, futhi ijeli elakhiwe liyoba isisombululo futhi ngemva kokupholisa.
◆ Umsebenzi ongaphezulu: Nikeza umsebenzi ongaphezulu kusixazululo sokufeza i-emulsification edingekayo kanye ne-colloid evikelayo, kanye nokuqiniswa kwesigaba.
◆Ukumiswa: I-Hydroxypropyl methylcellulose ingavimbela izinhlayiya eziqinile ukuthi zingahlali, ngaleyo ndlela ivimbele ukwakheka kwemvula.
◆I-colloid evikelayo: Ingavimbela amaconsi nezinhlayiya ukuthi zihlangane noma zihlangane.
◆Ukunamathela: Kusetshenziswa njengesinamatheliso semibala, imikhiqizo kagwayi, nemikhiqizo yephepha, kunemisebenzi emihle kakhulu.
◆I-Solubility Yamanzi: Umkhiqizo ungancibilika emanzini ngamanani ahlukene, futhi ukugxila kwawo okuphezulu kukhawulelwe kuphela yi-viscosity.
◆Ukungena kwe-ionic okungeyona i-ionic: Umkhiqizo i-ether ye-cellulose engeyona i-ionic, engahlangani nosawoti wensimbi noma amanye ama-ion ukuze kwakhe izimvula ezingancibiliki.
◆Ukuzinza kwe-Acid-base: kulungele ukusetshenziswa ngaphakathi kwebanga le-PH3.0-11.0.
◆ Ayinambitheki futhi ayinaphunga, ayithinteki kumetabolism;esetshenziswa njengezithasiselo zokudla nezidakamizwa, ngeke zigaywe nge-metabolized ekudleni, futhi ngeke zinikeze ukushisa.
