Yintoni umahluko phakathi kwe-HPMC kunye ne-MC

I-MC ye-methyl seluplose, efunyenweyo ngokuphatha i-cotton ecocekileyo ne-Alkali, esebenzisa i-methyl chloride njengearhente yokuthetha, kunye nokwenza i-teetseese ngothotho lwezinto ezikhoyo. Ngokubanzi, inqanaba lokufakwa endaweni le-1.6 ~ 2.0, kwaye i-solinoing nayo yahlukile ngamanqanaba ahlukeneyo okufaka endaweni. Yeyokwesi-i-ionic selsulose ether.

(1) Ukugcinwa kwamanziI-Methyl SeleloseKuxhomekeka kwisixa songezwa, i-viscosity, ukulunga kwemali kunye nexabiso lokuchitha. Ngokubanzi, ukuba isixa esongeziweyo sikhulu, ukulunga kuncinci, kwaye i-vickosity inkulu, inqanaba lokugcina amanzi liphezulu. Phakathi kwazo, inani elongezelelekileyo linefuthe elikhulu kwiqondo lokugcina amanzi, kwaye inqanaba le-viscofity alinayo elilinganayo kwinqanaba lokugcina amanzi. Inqanaba lokuchithwa ikakhulu lixhomekeka kwinqanaba lokutshintsha komphezulu wesuntswana kunye nobulungisa bamasuntswana. Phakathi kwezi zinto zingentla kwe-Sethes, iMethyl Selelose kunye neHydroxypropyl Methyl Selelose anemilinganiselo ephezulu yokugcina amanzi.

. Ihambelana ngokuchanekileyo nesitatshi, i-Gum Gum, njl. Njl. Xa iqondo lobushushu lifikelela kubushushu becandelo, into etyhafileyo yenzekile.

(3) Ukutshintsha kobushushu kuya kuchaphazela kakubi inqanaba lokugcinwa kwamanzi kwi-methyl seluplose. Ngokubanzi, amaqondo obushushu aphezulu, okuphezulu kokugcina amanzi. Ukuba ubushushu obuphanga bungaphezulu kwe-40 ° C, ukugcinwa kwamanzi kwe-methyl seluplose kuya kuba kubi kakhulu, nto leyo iya kuchaphazela kakhulu ukusebenza kodaka.

. "Ukubamba" apha kubhekisa kwi-Adhesions ebonakala phakathi kwesixhobo somsebenzi wesicelo sowokwenza isicelo somsebenzi kunye nodonga, oko kukuthi, ukumelana nodaka. Umlinganiso mkhulu, ukumelana nodaka kuphakanyiswa, kwaye amandla afunwa ngabasebenzi kwinkqubo yokusetyenziswa inkulu, kwaye ukwakhiwa kodaka akunakwenzeka. I-methylcelcelsulose Adherion ikwinqanaba eliphakathi kwimveliso ye-etelulose etele.

I-HPMC yi-HydroxyPOpyl Methyl Selelose, engu-Ionic selsulose exutywe ye-ether edibeneyo emva konyango lwe-Alkali, esebenzisa i-proplene oxide kunye ne-methyl chloride njengokuphendula. Inqanaba lokufakwa endaweni yi-1.2 ukuya kwi-2.0. Iipropathi zayo ziyahluka kuxhomekeka kwinxalenye yemixholo ye-APENGSYL kunye nomxholo we-hydroxypropy.

. Kodwa iqondo lokuhlaselwa layo lokuhlaselwa kwamanzi ashushu liphezulu kakhulu kune-methyl seluplose. Ukupheliswa kwamanzi abandayo kukuphuculwa kakhulu xa kuthelekiswa neMethyl Selelose.

. Ubushushu buchaphazela i-viscofity yayo, njengoko amaqondo obushushu ayanda, i-viscosity ihla. Kodwa i-viscofity yayo ayichanekanga kubushushu obuphezulu kune-methyl sellyulose. Isisombululo sayo sizinzile kwisitoreji kubushushu begumbi.

. I-Caustic Soda kunye namanzi e-lime anempembelelo encinci ekusebenzeni kwayo, kodwa uAlkali unokukhawulezisa ukuchitheka kwayo kunye nokonyusa i-viscofity. I-HydroxyPOpyl Methylcelcelgalose iZinzile kwi-SATTs eqhelekileyo, kodwa xa uxinzelelo lwesohlwayo luphezulu, i-viscosity ye-hydroxlypropyl methylcelces isisombululo sithanda ukunyuka kwesisombululo.

(4) Ukugcinwa kwamanzihydroxypropyl methylcelceluploseKuxhomekeka kwisixa songezwa, i-viscofity, njl. njl.

. Ezinjenge-polyvinyl utywala, i-starch ether, i-gum yemifuno, njl.
