Umlinganiselo othile we-hydroxypropyl methylcellulose ether ugcina amanzi kumdaka ixesha elaneleyo lokukhuthaza i-hydration eqhubekayo ye-cement kunye nokuphucula ukubambelela phakathi kodaka kunye ne-substrate.
Impembelelo yobungakanani beParticle kunye nexesha lokuxuba iHydroxypropyl Methyl Cellulose Ether ekuGcineni kwamanzi
Umthamo wokugcina amanzi wodaka ulawulwa kakhulu ngexesha lokuchithwa, kwaye i-cellulose ecocekileyo iyancibilika ngokukhawuleza, kwaye ngokukhawuleza ukugcinwa kwamanzi amandla. Ukwakhiwa komatshini, ngenxa yokunyanzeliswa kwexesha, ukhetho lwe-cellulose kufuneka lube ngumgubo ococekileyo. Ukutyabeka ngesandla, umgubo ocolekileyo uya kwenza.
Isiphumo se-Etherification Degree kunye noBushushu beHydroxypropyl Methyl Cellulose Ether ekuGcineni Amanzi
Ukunyibilika kunye nobushushu be-hydroxypropyl methylcellulose emanzini kuxhomekeke kwiqondo le-etherification. Njengoko ukushisa kwangaphandle kuphakama, ukugcinwa kwamanzi kunciphisa; iqondo eliphezulu le-etherification, kokukhona ukugcinwa kwamanzi kwe-cellulose ether.
Impembelelo ye-hydroxypropyl methylcellulose ether kwi-consistency kunye nokumelana nokutyibilika kodaka.
Ukungaguquguquki kunye nepropathi echasene nokutyibilika kodaka zizalathisi ezibaluleke kakhulu, zombini kulwakhiwo olungqingqwa kunye nokuncamathelisa kwethayile kufuna ukuhambelana okufanelekileyo kunye nepropathi echasene nokutyibilika.
Indlela yokuvavanya ukuhambelana, inqunywe ngokwe-JG/J70-2009 standard
Ukungaguquguquki kunye nokumelana nokutyibilika kubonakaliswa ikakhulu yi-viscosity kunye nobungakanani besuntswana le-hydroxypropyl methylcellulose. Ngokunyuka kwe-viscosity kunye nomxholo, ukuhambelana komdaka kwanda; Okukhona ubungakanani bamasuntswana bucoleke, kokukhona buphezulu ukuhambelana kokuqala kodaka oluxutywe ngokutsha. ngokukhawuleza.
Isiphumo seHydroxypropyl Methyl Cellulose kuNgeniso loMoya lodaka
Ngenxa yokongezwa kwe-hydroxypropyl methylcellulose kumdaka, umlinganiselo othile wamaqamza omoya amancinci, afanayo kunye nozinzile angeniswa kudaka olutsha oluxutywe. Ngenxa yomphumo webhola, udaka lunokwakhiwa kakuhle kwaye lunciphisa ukucutheka kunye nokuxhatshazwa komdaka. Ukuqhekeka, kunye nokunyusa izinga lemveliso yodaka. I-Cellulose inomsebenzi wokungenisa umoya. Xa ufaka i-cellulose, qwalasela i-dosage, i-viscosity (i-viscosity ephezulu kakhulu iya kuchaphazela ukusebenza), kunye neempawu zokungenisa umoya. Khetha i-cellulose kwiidaka ezahlukeneyo.
