Izakhiwo ze-Hydroxypropyl methylcellose HPMC

I-cellulose tallulose esetshenziswa kakhulu ifaka i-HEC, i-HPMC, CMC, PAC, Mhec nokunye. I-non-ionic ether-soluble cellulose ether inama-adhesser, ukuqina kokusakazeka kanye nomthamo wokugcina amanzi, futhi kuyisengezo esisetshenziswa kakhulu sezinto zokwakha. I-HPMC, i-MC noma i-EHEC isetshenziswa ekwakhiweni okuningi okususelwa kumasimende noma e-gypsum, njengodaka ngodaka, ukunamathela kosimende, ukuthuthukisa i-milky, okubaluleke kakhulu ngodaka, okubaluleke kakhulu ku-plaster, usimende we-tile kanye nesimende kanye nesimende. I-HEC isetshenziswa usimende, hhayi kuphela njengomthengisi, kodwa futhi njenge-ejenti yokugcina amanzi. IHehpc nayo inalolu hlelo lokusebenza.

Imikhiqizo ye-Hydroxypropylylylylylc hpmc ihlanganisa izakhiwo eziningi zomzimba nezamakhemikhali emikhiqizweni eyingqayizivele enezindlela ezahlukahlukene zokusetshenziswa nezakhiwo:

Ukugcinwa kwamanzi: Kungagcina amanzi ezindaweni eziphakemeyo ezinjengamabhodi odonga nezitini.

Ukudalwa kwefilimu: Kungakha ifilimu esobala, enzima futhi ethambile ngokumelana kwamafutha amahle kakhulu.

I-Organic Solubic: Umkhiqizo uyanyibilika kwezinye izixazululo ze-organic, njengokulingana okufanele kwe-ethanol / wamanzi, i-propapol / amanzi, i-dichloroethene kanye nohlelo lwe-solvent kanye nohlelo lwe-solvent oluhlanganiswe nezinhlelo ezimbili ze-organic.

I-Thermal Gelation: Lapho ikhambi elinamanzi lomkhiqizo lishisa, ijeli lizokwakha, futhi ijeli elakhiwe lizobuyela esikhambeni lapho selipholile.

Umsebenzi ongaphezulu: uhlinzeka ngemisebenzi yendawo yesixazululo ukufeza i-emulsalfication edingekayo nama-colloids avikelayo, kanye nokuqina kwesigaba.

Ukumiswa: I-Hydroxypropyllykyl Methylcellulose ivimbela izinhlayiya eziqinile ekuxazululeni, ngaleyo ndlela kuvinjelwe ukwakheka kwama-sedimentnts.

I-colloids evikelayo: Vimbela amaconsi nezinhlayiya kusuka ekuhlanganiseni noma ekuhlanganiseni.

I-SAMELBULE: Umkhiqizo ungachithwa emanzini ngamanani ahlukene, ukugxila okuphezulu okukhawulelwe kuphela ngokubonakala.

I-nonic inertness: Umkhiqizo uyi-ether engeyona eye-celvule

Ukuqina kwesisekelo se-Acid-Base: Ilungele ukusetshenziswa ebangeni le-PH3.0-11.0.
