Ukwenziwa kweSicelo se-HPMC
IHydroxypropyl methyl cellulose (HPMC) luhlobo lwe-non-ionic cellulose ether, eyenziwe ngezinto zepolymer zendalo njengezinto eziluhlaza kwaye zicocwe luthotho lweenkqubo zemichiza. Namhlanje siza kufunda malunga nokusebenza kwesicelo se-HPMC.
● I-solubility yamanzi: inokunyibilika emanzini nakweyiphi na imilinganiselo, i-concentration ephezulu ixhomekeke kwi-viscosity, kwaye ukuchithwa akuchaphazeli i-PH.l ye-Solubility Organic: I-HPMC inokuchithwa kwezinye i-solvents eziphilayo okanye i-organic solvent aqueous solutions ezifana ne-dichloroethane, isisombululo se-ethanol, njl.
● Iimpawu ze-Thermal gel: I-gel eguqulwayo iya kubonakala xa isisombululo sazo samanzi sifudumala kwiqondo lokushisa elithile, kunye nokusebenza okulawulwayo okukhawulezayo.
● Akukho ntlawulo ye-ionic: I-HPMC yi-ether ye-cellulose engeyiyo i-ionic kwaye ayiyi kuxakeka kunye neeyoni zetsimbi okanye i-organics ukwenza i-precipitates enganyibilikiyo.
● Ukujiya: Inkqubo yonyibiliko lwawo lwamanzi iye yaqina, kwaye isiphumo sokujiya sinxulumene nokubonakala kwayo, ukugxininiswa kwayo kunye nenkqubo.
● Ukugcinwa kwamanzi: I-HPMC okanye isisombululo sayo sinokufunxa kwaye sigcine amanzi.
● Ukwenziwa kwefilimu: I-HPMC inokwenziwa ibe yifilim egudileyo, eyomeleleyo, neelastiki, kwaye inegrisi egqwesileyo kunye nokumelana ne-oxidation.
● Ukuxhathisa i-Enzyme: Isisombululo se-HPMC sinokuxhathisa i-enzyme kunye nokuzinza okulungileyo kwe-viscosity.
● Ukuzinza kwe-PH: I-HPMC izinzile kwi-asidi kunye ne-alkali, kwaye i-pH ayithinteki kuluhlu lwe-3-11. (10) Umsebenzi womphezulu: I-HPMC ibonelela ngomsebenzi ongaphezulu kwisisombululo sokufezekisa i-emulsification efunekayo kunye nemiphumo yokukhusela i-colloid.
● Ipropathi yokuchasana ne-Anti-sagging: I-HPMC yongeza iipropati ze-thixotropic zenkqubo kwi-putty powder, i-mortar, i-tile glue, kunye nezinye iimveliso, kwaye inekhono elihle lokuchasa ukuguqa.
● I-Dispersibility: I-HPMC inokunciphisa ukunyanzeliswa kwe-interfacial phakathi kwezigaba kwaye yenze isigaba esisasazekayo sihlakazwe ngokufanayo sibe ngamaconsi obungakanani obufanelekileyo.
● Ukuncamathelisa: Ingasetyenziswa njengesibophelelo soxinaniso lwepigment: 370-380g/l³ iphepha, kwaye ingasetyenziswa kwiityali kunye nezinto ezincamathelayo.
● Ukuthambisa: Inokusetyenziswa kwirabha, iasbestos, isamente, kunye neemveliso zeceramic ukunciphisa ukukhuhlana nokuphucula ukugqobhoza kodaka lwekhonkrithi.
● Ukumiswa: Kunokuthintela iinqununu ezisisigxina kwimvula kwaye zithintele ukubunjwa kwemvula.
● I-Emulsification: Ngenxa yokuba inokunciphisa umphezulu kunye noxinzelelo lwe-interfacial, inokuzinzisa i-emulsion.
● I-colloid ekhuselayo: Uluhlu olukhuselayo lwenziwa phezu kwamaconsi ahlakaziweyo ukukhusela amaconsi ekudibaneni kunye ne-agglomerating ukufikelela kwisiphumo esizinzile sokukhusela.
