Ma hope o ka hoʻohui ʻana i ka hydroxypropyl methylcellulose i nā mea sima, hiki ke mānoanoa. ʻO ka nui o ka hydroxypropyl methylcellulose e hoʻoholo i ka koi wai o nā mea i hoʻokumu ʻia i ka sima, no laila e hoʻopilikia i ka hoʻopuka o ka mortar.
Hoʻopili kekahi mau mea i ka viscosity o ka hydroxypropyl methylcellulose:
1. ʻO ke kiʻekiʻe o ka polymerization o cellulose ether, ʻoi aku ka nui o kona kaumaha mole, a ʻoi aku ka kiʻekiʻe o ka viscosity o ka wai wai;
2. ʻO ke kiʻekiʻe o ka ʻai ʻana (a i ʻole ka ʻike) o ka cellulose ether, ʻoi aku ka kiʻekiʻe o ka viscosity o kāna ʻano wai. Eia nō naʻe, pono e noʻonoʻo i ke koho ʻana i ka intake kūpono i ka wā o ka noi e pale aku i ka lawe nui ʻana, kahi e hoʻopilikia ai i ka hana o ka mortar a me ke koneki. hiʻona;
3. E like me ka nui o nā wai, e emi ana ka viscosity o ka solution cellulose ether me ka piʻi ʻana o ka mahana, a ʻoi aku ka kiʻekiʻe o ka neʻe ʻana o ka cellulose ether, ʻoi aku ka nui o ka mana o ka wela;
4. ʻO ka solution hydroxypropyl methylcellulose he pseudoplastic maʻamau, nona ka waiwai o ka shear thinning. ʻOi aku ka nui o ka shear rate i ka wā o ka hoʻāʻo ʻana, ʻoi aku ka haʻahaʻa o ka viscosity.
No laila, e emi ana ka hui ʻana o ka pāpaʻa ma muli o ka ikaika o waho, kahi mea e pono ai i ke kālai ʻia ʻana o ka palaki, e hopena ai i ka hana maikaʻi a me ka hui pū ʻana o ka mortar i ka manawa like.
E hōʻike ana ka solution hydroxypropyl methylcellulose i nā hiʻohiʻona wai o Newtonian ke haʻahaʻa loa ka ʻike a haʻahaʻa ka viscosity. Ke piʻi aʻe ka manaʻo, e hōʻike mālie ka hopena i nā ʻano wai pseudoplastic, a ʻoi aku ka kiʻekiʻe o ka ʻike, ʻoi aku ka maopopo o ka pseudoplasticity.
