IHydroxypropyl methyl cellulose ether yokwakhiwa

Iimpawu zemveliso ye-hydroxypropyl methylcellulose yokwakhiwa

Inyibilika emanzini kunye nezinye izinyibilikisi eziphilayo. Inokunyibilika emanzini abandayo. Ukugxininiswa kwayo okuphezulu kuxhomekeke kuphela kwi-viscosity. I-solubility iyatshintsha kunye ne-viscosity. I-viscosity ephantsi, i-solubility enkulu.

I-hydroxypropyl methylcellulose enganyangekiyo kwisakhiwo esithile yi-ether ye-cellulose engeyo-ionic, kwaye ayiyo-polyelectrolyte, ngoko ke izinzile kwisisombululo samanzi phambi kweetyuwa zetsimbi okanye i-electrolytes ephilayo, kodwa ukongezwa ngokugqithiseleyo kwe-electrolytes kunokubangela i-gelation kunye nemvula. .

Umsebenzi womphezulu Ngenxa yokuba isisombululo samanzi sinomsebenzi womsebenzi womphezulu, sinokusetyenziswa njenge-agent ekhuselayo ye-colloidal, i-emulsifier kunye ne-dispersant. Xa isisombululo samanzi se-hydroxypropyl methylcellulose yokwakha sifudunyezwa kwiqondo lokushisa elithile, liba li-opaque, i-gels, kunye ne-precipitates, kodwa xa lipholile ngokuqhubekayo, libuyela kwimeko yesisombululo sokuqala, kwaye le gel kunye nemvula yenzeke Ubushushu buxhomekeke ubukhulu becala. kwii-lubricants zabo, i-agent yokumisa, i-colloids yokukhusela, i-emulsifiers, njl.

Ukunganyangeki kokungunda Inamandla okumelana nokungunda kunye nokuzinza okuhle kwe-viscosity ngexesha lokugcinwa kwexesha elide.

Ukuzinza kwe-PH, i-viscosity ye-hydroxypropyl methylcellulose isisombululo se-aqueous sakhiwo ayinakuchaphazeleka nge-asidi okanye i-alkali, kwaye ixabiso le-pH lizinzile kuluhlu lwe-3.0 ukuya kwi-11.0.

Ukugcinwa kobume Ekubeni isisombululo esinamanzi esigxininiswe kakhulu se-hydroxypropyl methylcellulose yokwakha sineempawu ezikhethekileyo ze-viscoelastic xa kuthelekiswa nezisombululo ezinamanzi zezinye iipolymers, ukongezwa kwayo kunokuphucula ukukwazi ukugcina imilo yeemveliso ze-ceramic ezikhutshiweyo.

Ukugcinwa kwamanzi I-Hydroxypropyl methylcellulose yokwakha luhlobo lwe-ejenti ephezulu yokugcina amanzi ngenxa ye-hydrophilicity ephezulu kunye ne-viscosity ephezulu yesisombululo sayo samanzi. Ezinye iipropati ze-Thickener, i-agent-forming agent, i-binder, i-lubricant, i-agent yokumisa, i-colloid ekhuselayo, i-emulsifier, njl.
