ʻO ke kūkulu ʻana i ka hydroxypropyl methyl cellulose kūikawā e pale aku i ka komo ʻana o ka makū i ka paia, e lawa ka nui o ka makū e noho ai i loko o ka sima mortar e hana i ka hana maikaʻi i ka wai a ʻo ke kuleana o ka hydroxypropyl methyl cellulose i loko o ka mortar e kūlike me ka viscosity, ʻoi aku ka maikaʻi o ka viscosity o ka hydroxypropyl methyl cellulose i ka paʻa ʻana o ka wai.
Ke kiʻekiʻe loa ka makū o ka hydroxypropyl methyl cellulose, e emi ana ka paʻa ʻana o ka wai o ka hydroxypropyl methyl cellulose, a e alakaʻi pololei ia i ka pono o ke kūkulu ʻana o ka hydroxypropyl methyl cellulose. Ua kamaʻāina hoʻi mākou i nā mea e maʻalahi ai ke hana hewa, pono mākou e mālama mau i ka hou, e loaʻa iā mākou nā hopena i manaʻo ʻole ʻia.
ʻO ka viscosity maopopo kahi helu koʻikoʻi o ka hydroxypropyl methyl cellulose. ʻO nā ʻano ana maʻamau ka ana ʻana o ka viscosity rotational, ke ana ʻana o ka viscosity capillary a me ke ana ʻana o ka viscosity hāʻule.
Ma mua, ua hoʻoholo ʻia ka hydroxypropyl methyl cellulose e ke ana ʻana o ka viscosity capillary, me ka hoʻohana ʻana i ka viscometer Uhnscher. ʻO ka hopena ana he hopena wai o 2, a ʻo ke ʻano hana: V = Kdt. ʻO V ka viscosity i kekona, ʻo K ke kūpaʻa o ka viscometer, ʻo D ka density ma ka mahana mau, a ʻo T ka manawa e pono ai e hele mai luna a lalo o ka viscometer i kekona. ʻOi aku ka paʻakikī o kēia ʻano hana, inā he mea hiki ʻole ke hoʻoheheʻe ʻia, maʻalahi ke hana i nā hewa, paʻakikī ke ʻike i ka maikaʻi o ka hydroxypropyl methylcellulose.
ʻO ka pilikia o ke kūkulu ʻana i ka stratification glue he pilikia nui ia i loaʻa i nā mea kūʻai aku. ʻO ka mea mua, pono e noʻonoʻo ʻia ka pilikia o nā mea maka no ka stratification glue hale. ʻO ke kumu nui no ka stratification glue hale ʻo ia ka kūlike ʻole ma waena o ka polyvinyl alcohol (PVA) a me ka hydroxypropyl methylcellulose (HPMC). ʻO ke kumu ʻelua, ʻaʻole lawa ka manawa hui ʻana; Aia pū kekahi, ʻaʻole maikaʻi ka hana mānoanoa o ke kāpili hale.
I ke kūkulu ʻana i nā kāpili, pono e hoʻohana koke ʻia ka hydroxypropyl methylcellulose (HPMC) no ka mea ua hoʻopuehu wale ʻia ka HPMC i ka wai a ʻaʻole hoʻoheheʻe maoli. Ma kahi o 2 mau minuke, piʻi mālie ka mānoanoa o ka wai, e hana ana i kahi colloid viscous moakaka.
Hiki ke hoʻopuehu koke ʻia nā huahana hoʻoheheʻe wela i ka wai anuanu i ka wai wela, a laila nalowale i ka wai wela. Ke hāʻule ka mahana i kekahi mahana, e ʻike mālie ʻia ka mānoanoa, a hiki i ka hoʻokumu ʻia ʻana o kahi colloid viscous moakaka. Manaʻo ʻia ka nui o ka hoʻohui ʻana o ka Hydroxypropyl methylcellulose (HPMC) i loko o ke kāpili hale no 2-4kg.
He maikaʻi ka hopena o ka hydroxypropyl methyl cellulose (HPMC) i ka hoʻopili ʻana i ke kemika o ka hale, he maikaʻi ka hopena o ka paʻa ʻana o ka wai, ʻaʻole ia e hoʻopilikia ʻia e ka loli o ka PH, hiki ke hoʻohana ʻia ka viscosity mai 100,000 S - 200,000 S. Akā i ka hana ʻana, ʻaʻole ʻoi aku ka maikaʻi o ka viscosity kiʻekiʻe, ʻoi aku ka like o ka viscosity a me ka ikaika o ka hoʻopaʻa ʻana, ʻoi aku ka liʻiliʻi o ka ikaika, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka liʻiliʻi o ka ikaika, ma ke ʻano laulā, kūpono ka viscosity 100,000S.
