Hydroxypropyl methyl cellulose(hpmc)hoʻohana maʻamau i ka pauka putty me ka viscosity o 100000, ʻoiai ʻo ka mortar he mau koi kiʻekiʻe no ka viscosity a pono e koho ʻia me ka viscosity o 150000 no ka hoʻohana maikaʻi ʻana. ʻO ka hana nui loa ohydroxypropyl methyl cellulosee mālama i ka wai, a ma hope o ka mānoanoa. No laila, i ka pauka putty, ʻoiai ka lōʻihi o ka paʻa ʻana o ka wai a haʻahaʻa ka viscosity, hiki nō hoʻi. ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai. Eia nō naʻe, ke ʻoi aku ka viscosity ma mua o 100000, ʻaʻole nui ka hopena o ka viscosity i ka mālama ʻana i ka wai.

ʻO ka papa hale hale ʻo JufuHydroxypropyl Methyl CelluloseHoʻokaʻawale ʻia e ka Viscosity, hoʻokaʻawale ʻia i nā ʻano aʻe:

1. Haʻahaʻa viscosity: 400 viscosity cellulose, i hoʻohana nui ʻia no ka hoʻomaʻamaʻa ponoʻī. ʻO ka viscosity haʻahaʻa, kahe maikaʻi, a ma hope o ka hoʻohui, e hoʻomalu ia i ka paʻa ʻana o ka wai. ʻAʻole ʻike ʻia ke koko, liʻiliʻi ka emi ʻana, a hoʻemi ʻia ka pohā. Hiki iā ia ke pale aku i ka sedimentation, hoʻonui i ka flowability a me ka pumpability.
2. Medium a haʻahaʻa viscosity: 20000 a 50000 viscosity cellulose, hoʻohana nui ʻia no nā huahana gypsum a me nā mea hoʻopihapiha hui. ʻO ka viscosity haʻahaʻa, ka paʻa wai maikaʻi, ka hana maikaʻi, a me ka hoʻohui wai haʻahaʻa,
3. Medium viscosity: 75000-100000 viscosity cellulose, hoʻohana nui ʻia no ka putty pā o loko a me waho. ʻO ka viscosity haʻahaʻa, ka paʻa wai maikaʻi, a me ka drape kūkulu maikaʻi.
4. Kiʻekiʻe viscosity: 150000 a 200000 yuan, hoʻohana nui ʻia no ka polystyrene particle insulation mortar powder material, vitrified micro bead insulation mortar me ka viscosity kiʻekiʻe a me ka paʻa wai. ʻAʻole maʻalahi ka hāʻule a kau ʻana o ka mortar, hoʻomaikaʻi i ke kūkulu ʻana.
ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai. No laila, koho ka nui o nā mea kūʻai aku e hoʻohana i ka cellulose viscosity medium (75000-100000) ma kahi o ka cellulose viscosity haʻahaʻa haʻahaʻa (20000-50000) e hōʻemi i ka nui o ka hoʻohui a me nā kumukūʻai.
ʻO ka viscosity oHPMCua like ka like me ka mahana, ʻo ia hoʻi, piʻi ka viscosity me ka emi ʻana o ka mahana. ʻO ka viscosity o ka huahana ʻo ia ka 2% solution ma kahi mahana o 20 degere Celsius, a pololei nā hopena hōʻike.
Ma nā noi kikoʻī, pono e uku ʻia i nā wahi me nā ʻokoʻa wela nui ma waena o ke kauwela a me ka hoʻoilo, a manaʻo nui ʻia e hoʻohana i ka viscosity haʻahaʻa i ka hoʻoilo. Inā ʻaʻole, inā haʻahaʻa ka viscosity, e piʻi ka viscosity o cellulose a kaumaha nā ʻōpala.
