ʻO ka Hydroxypropyl methylcellulose (HPMC) i loko o ka pahū pulu pulu

ʻO ke kuleana oʻO HPMC i loko o ka hamo i hui pū ʻia

ʻO ka mortar wet-mixed he sima, hui maikaʻi, admixture, wai a me nā mea like ʻole i hoʻoholo ʻia e like me ka hana. Wahi a kekahi hapa, ma hope o ke ana ʻana a hui ʻia i loko o ke kahua hui, lawe ʻia ia i kahi o ka hoʻohana ʻana e kahi kaʻa huila, a hoʻokomo ʻia i loko o kahi mea kūikawā.

Hoʻohana ʻia ka Hydroxypropyl methylcellulose ma ke ʻano he mea pale no ka slurry sima a ma ke ʻano he retarder e hana i ka slurry pumpable. ʻO ka Hydroxypropyl-Methyl Cellulose HPMC Cellulose hiki ke hoʻomaʻemaʻe ma ke ʻano he hopena viscous e hoʻonui i ka pono o ka dab a hoʻonui i ka manawa hana. ʻO kēia ka mea e hiki ai i ka sesame ke pohā koke ma hope o ka lubrication a hoʻonui i ka ikaika ma hope o ka maloʻo. . ʻO ka waika hydrochloric kahi hana koʻikoʻi o ka HPMC e hydrolyze cellulose, a he mea hana ia i nā pulps he nui ma Kina. ʻO nā mea e pili ana i ka slurry pulu ʻo ia ka nui o ka hoʻohui ʻana o ka HPMC, ka viscosity HPMC, ka liʻiliʻi o ka ʻāpana a me ka mahana o ka ʻili.

ʻO ka hana koʻikoʻi o ka HPMC i loko o ka hui wai e hōʻike nui ʻia i ʻekolu mau ʻano: ʻo kekahi ka mana paʻa wai maikaʻi, ʻo ka mea ʻē aʻe ka mana i ka kūlike a me ka deformation sensory o ka hui pulu, a ʻo ka mea ʻē aʻe ka pilina me ka sima. ʻO ka nui o ka cellulose ether e pili ana i ka lawe ʻana o ka wai e ka substrate, ke ʻano o ke one, ka mānoanoa o ka papa, ka pono o ka wai i ka hopena, a me ka manawa condensation o ka mea.

ʻO nā mea e hoʻopaʻa ai i ka wai e pili ana i ka cellulose hydrolyzed e pili ana i ka viscosity pulp, ka nui o ka hoʻohui, ka liʻiliʻi a me ka mahana. ʻOi aku ka mānoanoa o ka cellulose ether, ʻoi aku ka maikaʻi o ka pale wai. ʻO ka Viscosity kahi mea hoʻohālike koʻikoʻi o ka HPMC. No ka huahana like, ʻokoʻa nā hopena viscosity i ana ʻia e nā ʻano hana like ʻole, a hiki i kekahi ke hele i ka holomua geometric. No laila, e hoʻohālikelike i nā viscosities, pono e hana ʻia ma waena o nā ʻano hoʻokolohua like, me ka mahana, spindle, etc.

ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka hana wai. Akā ʻoi aku ka nui o ka hoʻonui ʻana i ka viscosity, HPMC, ʻoi aku ka kiʻekiʻe o ke kaumaha mole, ʻoi aku ka haʻahaʻa o nā waiwai solubility, ikaika ka hopena, a ua hoʻopilikia maikaʻi ʻia nā waiwai. ʻOi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka hopena mānoanoa i ka hopena, akā ʻaʻole kūlike i ka ratio. ʻO ke kiʻekiʻe o ka viscosity, ʻoi aku ka wai a ʻoi aku ka viscous i ka hopena, i ka wā e kūkulu ai, e hōʻike ana i ke kūpaʻa kiʻekiʻe ma ke alo o nā lau a me nā mea. Akā, ʻaʻole kōkua ka hoʻohui ʻana i ka ikaika kūkulu i ka mortar pulu ponoʻī. I ka wā i kūkulu ʻia ai nā hale ʻelua, ua ʻike ʻia ua nalowale ka hana anti-namu. ʻO ka ʻokoʻa, ʻo kekahi mau haʻahaʻa haʻahaʻa post-modified methacrylic acid, ʻoiai ke hoʻomaikaʻi nei ka cellulose i ka hoʻonā wai a me ka ikaika o ke kūkulu ʻana, he waiwai maikaʻi loa.
