I-hydroxypropyl methylcellulose ether esheshayo yakhelwe imikhiqizo esekwe emanzini. Ingaphezulu le-hydroxypropyl methylcellulose ether liphathwa nge-glyoxal ngaphansi kwezinga lokushisa elithile kanye nenani le-pH. I-hydroxypropyl methyl cellulose ether ephathwa ngale ndlela ihlakazwa kuphela emanzini abandayo angathathi hlangothi ngaphandle kokuvuvukala kanye ne-viscosity, edlala indima ekubambezelekeni kokuvuvukala. Ngalesi sikhathi, isixazululo samanzi siyashukunyiswa imizuzu engu-5-10 noma Lapho indawo yesisombululo (i-PH value) ilungiswa ukuze ibe yi-alkaline, i-hydroxypropyl methylcellulose ether iqala ukuvuvukala futhi ikhiqize i-viscosity. Lolu hlobo olulashwe phezulu ngokuvamile lubizwa ngokuthi uhlobo olusheshayo.
Isici se-instant hydroxypropyl methylcellulose ukuthi uma ihlangana namanzi abandayo, izosakazeka ngokushesha emanzini abandayo, kodwa kuthatha isikhathi ukuthi i-viscosity yayo ikhuphuke, ngoba ihlakazeka emanzini kuphela ekuqaleni, futhi ayincibiliki emanzini. umqondo omkhulu. I-viscosity yayo ifinyelela inani eliphakeme cishe imizuzu engama-20 noma ngaphezulu. Inzuzo yalokhu ukuthi isetshenziswa embonini ethile ngaphandle kokuxuba i-powder eyomile, noma lapho idinga ukuchithwa futhi amanzi ashisayo angeke asetshenziswe ngenxa yezimo zemishini nezinye izizathu. I-hydroxypropyl methylcellulose esheshayo ixazulula inkinga enjalo.
I-hydroxypropyl methylcellulose esheshayo ihlakazeka ngokushesha emanzini (i-dispersion degree ingu-100%), incibilika ngokushesha, ayihlanganisi, ikakhulukazi esigabeni sakamuva, isixazululo se-colloidal sinokucaca okuphezulu (kufika ku-95%) nokuvumelana okukhulu, okuxazulula izinkinga. ezinhlelweni zokusebenza. Izithiyo, ukwandisa insimu isicelo, ezifana isicelo in ukwakhiwa glue, isicelo in kwakwakhe liquid admixtures, kanye nezinkambu ezikhethekile ezifana nsuku zonke ukugeza amakhemikhali.
Sethule imishini ethuthukisiwe yomhlaba yokukhiqiza nobuchwepheshe, sibe nomugqa wesimanje wokukhiqiza we-cellulose ether kanye ne-latex powder ehlakazeka kabusha, futhi siqinisekisa ukunikeza abasebenzisi imikhiqizo egculisayo ngohlelo lwayo oluqinile lokulawula ikhwalithi, uhlelo lokuhlola kanye nenkonzo ephelele esizeni. Manje imikhiqizo ehamba phambili i-hydroxypropyl methylcellulose HPMC, i-hydroxyethyl cellulose HEC, i-hydroxypropyl isitashi ether HPS, uchungechunge lwe-latex powder oluphindayo. Imikhiqizo isetshenziswa kabanzi ekwakhiweni, embonini yamakhemikhali, ngopende, embonini yamakhemikhali yansuku zonke, imboni yezempi nezinye izinkambu, futhi ngokulandelana kwenziwa ama-ejenti abumba ifilimu, izinto zokunamathisela, izisabalalisi, iziqinisi, ama-thickeners, njll.
Ithembele kukhwalithi yayo yomkhiqizo kanye nesimo sayo kanye nomthelela embonini yokwengeza izinto zokwakha ngempuphu eyomile, futhi ngaphansi kwesisekelo sokugcina njalo umgomo wenkampani wekhwalithi kuqala, manje isisebenzisana nabakhiqizi bamazwe ngamazwe nabasekhaya abaziwayo bemikhiqizo ehambisanayo. Imisebenzi esekelayo: i-polypropylene fibre, i-Wood fiber, i-modified starch ether, i-polyvinyl alcohol powder, i-powder defoamer, isinciphisi samanzi, isixosha amanzi, i-calcium formate nezinye izithasiselo zempuphu ezomile.
