Emva kokongeza i-hydroxypropyl methylcellulose kwizinto ezisekwe kwisamente, inokuba nkulu. Ubungakanani be-hydroxypropyl methylcellulose bumisela imfuno yamanzi yezinto ezisekwe kwisamente, ngoko ke iya kuchaphazela imveliso yesamente.
Ziliqela izinto ezichaphazela i-viscosity ye-hydroxypropyl methylcellulose:
1. Okukhona inqanaba eliphezulu le-polymerization ye-cellulose ether, kokukhona ubunzima bayo be-molecular bukhulu, kwaye kokukhona i-viscosity yesisombululo samanzi iphezulu;
2. Okukhona i-cellulose ether ingena kakhulu (okanye i-concentration) ephezulu, kokukhona i-viscosity yesisombululo sayo samanzi iphezulu. Nangona kunjalo, kuyimfuneko ukuqwalasela ukukhetha i-induction efanelekileyo ngexesha lokusetyenziswa ukuze kuthintelwe ukungenisa kakhulu, okuya kuchaphazela umsebenzi we-mortar kunye ne-concrete.
3. Njengoninzi lweziselo, i-viscosity yesisombululo se-cellulose ether iya kuncipha ngokunyuka kobushushu, kwaye okukhona uxinzelelo lwe-cellulose ether luphezulu, kokukhona impembelelo yobushushu iba nkulu;
4. Isisombululo se-hydroxypropyl methylcellulose sidla ngokuba yi-pseudoplastic, eneempawu zokucheba. Okukhona izinga lokucheba liphezulu ngexesha lovavanyo, kokukhona i-viscosity iphantsi.
Ngoko ke, ukudibana kwesamente kuya kuncipha ngenxa yamandla angaphandle, nto leyo eluncedo ekwakheni isamente esikrwela, nto leyo ekhokelela ekusebenzeni kakuhle nasekuhlanganeni kwesamente ngaxeshanye.
Isisombululo se-hydroxypropyl methylcellulose siza kubonisa iimpawu zolwelo lweNewtonian xa uxinzelelo luphantsi kakhulu kwaye i-viscosity iphantsi. Xa uxinzelelo lusanda, isisombululo siza kubonisa iimpawu zolwelo lwe-pseudoplastic kancinci kancinci, kwaye okukhona uxinzelelo luphezulu, kokukhona i-pseudoplasticity icaca ngakumbi.
