Ukusebenza Kwesicelo se-HPMC
IHydroxypropyl methyl cellulose (HPMC) iwuhlobo lwe-non-ionic cellulose ether, elenziwe ngezinto zemvelo ze-polymer njengempahla eluhlaza futhi yacwengwa ngochungechunge lwezinqubo zamakhemikhali. Namuhla sizofunda ngokusebenza kwesicelo se-HPMC.
● Ukunyibilika kwamanzi: kungancibilika emanzini nganoma iyiphi ingxenye, ukugxila okuphezulu kakhulu kuncike ku-viscosity, futhi ukuncibilika akuthintwa yi-PH.l Organic solubility: I-HPMC ingancibilika kwezinye izinyibilikisi zemvelo noma izixazululo ze-organic solvent aqueous ezifana ne-dichloroethane, isixazululo se-ethanol, njll.
● Izici zejeli eshisayo: Ijeli ebuyiseleka emuva izovela uma isixazululo sayo samanzi sishiselwa ezingeni lokushisa elithile, nokusebenza kokusetha okusheshayo okulawulwayo.
● Ayikho i-ionic charge: I-HPMC iyi-ether engeyona i-ionic cellulose futhi ngeke ibe yinkimbinkimbi nama-ion ensimbi noma i-organics ukuze yakhe imvula engancibiliki.
● Ukuqina: Isimiso saso sesisombululo esinamanzi siyaqina, futhi umphumela wokujiya uhlobene nokubonakala kwawo, ukugxila kwawo, kanye nesistimu.
● Ukugcinwa kwamanzi: I-HPMC noma isisombululo sayo singamunca futhi sigcine amanzi.
● Ukwakhiwa kwefilimu: I-HPMC ingenziwa ibe ifilimu ebushelelezi, eqinile, futhi enwebekayo, futhi inomphumela omuhle kakhulu wokumelana namafutha kanye ne-oxidation.
● Ukumelana nama-enzyme: Isixazululo se-HPMC sinokumelana okuhle kakhulu kwe-enzyme kanye nokuzinza okuhle kwe-viscosity.
● Ukuzinza kwe-PH: I-HPMC izinzile uma kuqhathaniswa ne-asidi ne-alkali, futhi i-pH ayithinteki kububanzi obungu-3-11. (10) Umsebenzi ongaphezulu: I-HPMC inikeza umsebenzi ongaphezulu kusixazululo sokufeza i-emulsification edingekayo kanye nemiphumela ye-colloid evikelayo.
● Isici esinqanda ukuntengantenga: I-HPMC yengeza izinto ze-thixotropic zesistimu kumpushana we-putty, udaka, iglue yamathayela, neminye imikhiqizo, futhi inekhono elihle kakhulu lokunqanda ukuntengantenga.
● Ukuhlakazeka: I-HPMC inganciphisa ukungezwani kobuso phakathi kwezigaba futhi yenze isigaba esihlakaziwe sihlakazwe ngokufanayo sibe amaconsi anosayizi ofanele.
● Ukunamathela: Kungasetshenziswa njengesihlanganisi sokuminyana kwe-pigment: 370-380g/l³ iphepha, futhi kungasetshenziswa kuma-coatings nama-adhesives.
● I-Lubricity: Ingasetshenziswa kunjoloba, i-asbestos, usimende, nemikhiqizo yobumba ukuze kuncishiswe ukungqubuzana futhi kuthuthukiswe ukungeneka kwe-slurry kakhonkolo.
● Ukumiswa: Kungavimbela izinhlayiya ezingashintshi emvuleni futhi kuvimbele ukwakheka kwemvula.
● I-Emulsification: Ngenxa yokuthi inganciphisa ukungezwani okungaphezulu nokuhlangana kobuso, ingakwazi ukuzinzisa i-emulsion.
● I-colloid evikelayo: Ungqimba oluyisivikelo lwakhiwa phezu kwamaconsi ahlakazekile ukuze kuvinjelwe amaconsi ukuthi angahlangani futhi ahlangane ukuze kuzuzwe umphumela wokuvikela ozinzile.
