Hydroxypropyl Methylcellulose HPMC
I nā mea kūkulu hale, hoʻohana ʻia ia ma ke ʻano he mea mālama wai a me ka retarder no ka sludge sima me ka pumpability.Hiki ke hoʻohana ʻia ma ke ʻano he mea paʻa i ka plaster, gypsum, inverted powder a i ʻole nā mea kūkulu hale e hoʻomaikaʻi ai i ka pālahalaha a hoʻolōʻihi i ka manawa hana.Hiki ke hoʻohana ʻia ma ke ʻano he mea hana no ka hoʻopili ʻana i nā pōhaku lepo, nā tile, nā kinikini, nā mea hoʻonaninani plastik, a me nā mea hoʻoikaika paʻa.Hiki ke hoemi i ka nui o ka sima.ʻO ka mālama ʻana i ka waiHPMCpale i ka slurry mai ka pohā ma muli o ka maloʻo wikiwiki loa ma hope o ka uhi ʻana, a hoʻonui i ka ikaika ma hope o ka paʻakikī.
Eia kekahi, hoʻohana ʻia ia e like me ka mānoanoa, kūpaʻa, emulsifier, excipient, paʻa wai i ka hana ʻana i nā petrochemical ʻē aʻe, nā uhi, nā mea kūkulu hale, nā mea hoʻoneʻe pena, nā kemika mahiʻai, nā inika, ka paʻi lole a me ke kala, nā seramika, ka hana pepa, a me nā mea hoʻonaninani.Agent, mea hana kiʻiʻoniʻoni, etc.
