Ama-cellulose ether asetshenziswa kakhulu ahlanganisa i-HEC, i-HPMC, i-CMC, i-PAC, i-MHEC nokunye okunjalo.I-non-ionic water-soluble cellulose ether inokunamathela, ukuzinza kokuhlakazeka kanye namandla okugcina amanzi, futhi iyisengezo esisetshenziswa kakhulu ezintweni zokwakha.I-HPMC, i-MC noma i-EHEC isetshenziswa ezakhiweni eziningi ezisekelwe kusimende noma ezisekelwe ku-gypsum, njengodaka lwamatshe, udaka lukasimende, ukunamathela kukasimende, igypsum, ingxube kasimende, ne-milky putty, njll., engathuthukisa ukuhlakazeka kukasimende noma isihlabathi. futhi uthuthukise kakhulu i-Adhesion, ebaluleke kakhulu ku-plaster, usimende we-tile kanye ne-putty.I-HEC isetshenziswa kusimende, hhayi nje njenge-retarder, kodwa futhi njenge-ejenti yokugcina amanzi.I-HEHPC inalolu hlelo lokusebenza.
Imikhiqizo ye-Hydroxypropyl methylcellulose HPMC ihlanganisa izakhiwo eziningi ezibonakalayo namakhemikhali zibe yimikhiqizo eyingqayizivele esebenzisa izinto ezihlukahlukene kanye nezakhiwo:
Ukugcinwa kwamanzi: Ingagcina amanzi ezindaweni ezinezimbotshana ezifana namabhodi osimende odongeni nezitini.
Ukwenza ifilimu: Ingakha ifilimu esobala, eqinile futhi ethambile enokumelana okuhle kakhulu kwamafutha.
Ukunyibilika kwe-Organic: Umkhiqizo ungancibilika kwezinye izinyibilikisi zemvelo, njengezilinganiso ezifanele ze-ethanol/amanzi, i-propanol/amanzi, i-dichloroethane kanye nesistimu yokuncibilikisa eyakhiwe ngezincibilikizi ezimbili eziphilayo.
I-Thermal Gelation: Uma isixazululo esinamanzi somkhiqizo sishiswa, ijeli izokwakheka, futhi ijeli elakhiwe lizobuyela emuva libe yisixazululo lapho selipholile.
Umsebenzi ongaphezulu: Ihlinzeka ngomsebenzi ongaphezulu ekuxazululeni ukuze kuzuzwe i-emulsification edingekayo kanye nama-colloid avikelayo, kanye nokuqiniswa kwesigaba.
Ukumiswa: I-Hydroxypropyl methylcellulose ivimbela izinhlayiya eziqinile ukuthi zingahlali, ngaleyo ndlela ivimbele ukwakheka kwezinsalela.
I-Protective Colloids: Vimbela amaconsi kanye nezinhlayiya ukuthi zihlangane noma zihlangane.
I-Soluble Water : Umkhiqizo ungancibilika emanzini ngamanani ahlukene, ukugxila okuphezulu kukhawulelwe kuphela yi-viscosity.
Ukungangeni 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 ebangeni le-PH3.0-11.0.
