3、ʻano huahana
Nā Pono: He pauka keʻokeʻo a keʻokeʻo paha kēia huahana, ʻaʻala ʻole, ʻono ʻole aʻona ʻole.
Hiki ke hoʻoheheʻe ʻia ka wai a me ka mānoanoa: Hiki ke hoʻoheheʻe ʻia kēia huahana i loko o ka wai anuanu e hana ai i kahi hopena viscous akaka.
Hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik: No ka mea aia kekahi mau pūʻulu hydrophobic methoxyl, hiki ke hoʻoheheʻe ʻia kēia huahana i kekahi mau mea hoʻoheheʻe organik, a hiki ke hoʻoheheʻe ʻia i loko o nā solvents i hui pū ʻia me ka wai a me nā mea ola.
Ka pale paʻakai: No ka mea he polymer non-ionic kēia huahana, ʻano paʻa ia i nā hoʻonā wai o nā paʻakai metala a i ʻole nā electrolytes organik.
Hana ʻili: ʻO ka hoʻonā wai o kēia huahana he hana ma luna, a he mau hana a me nā waiwai e like me ka emulsification, colloid pale a me ke kūpaʻa pili.
Thermal gelation: Ke hoʻomehana ʻia ka wai wai o kēia huahana i kekahi mahana, lilo ia i opaque a hiki i ka hoʻokumu ʻana i kahi moku (poly) flocculation, i nalowale ka hopena i kona viscosity. Akā ma hope o ka hoʻoluʻu ʻana, e huli hou ia i ke kūlana hoʻonā kumu. ʻO ka mahana i loaʻa ai ka gelation e pili ana i ke ʻano o ka huahana, ke ʻano o ka hopena a me ka wikiwiki o ka hoʻomehana.
Paʻa PH: Paʻa ka viscosity o ka hoʻonā wai o kēia huahana i loko o ka laulā o PH3.0-11.0.
Ka hopena mālama wai: No ka mea he hydrophilic kēia huahana, hiki ke hoʻohui ʻia i ka mortar, gypsum, pena, etc.
Ka paʻa ʻana o ke ʻano: Ke hoʻohālikelike ʻia me nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, ʻo ka hoʻonā wai o kēia huahana he waiwai viscoelastic kūikawā. Hiki i kona hoʻohui ke mālama i ke ʻano o nā huahana ceramic extruded ʻaʻole i loli.
Lubricity: ʻO ka hoʻohui ʻana i kēia huahana hiki ke hōʻemi i ka coefficient friction a hoʻomaikaʻi i ka lubricity o nā huahana ceramic extruded a me nā huahana sima.
Nā waiwai hana kiʻiʻoniʻoni: Hiki i kēia huahana ke hana i kahi kiʻiʻoniʻoni maʻalahi a me ka ʻike me nā waiwai mechanical maikaʻi loa, a he ʻaila maikaʻi a me ka momona.

ʻOi aku ka nui o ka nui: 100 mesh pass rate ʻoi aku ka nui ma mua o 98.5%, 80 mesh pass rate he 100%
ʻO ka mahana carbonization: 280 ~ 300 ℃
ʻIke ʻia ka mānoanoa: 0.25~0.70/cm kikoʻī umekaumaha 1.26~1.31
Ka wela hoʻololi: 190~200 ℃
ʻO ke kuʻekuʻe ʻana o ka ʻili: 2% ka hopena wai he 42 ~ 56dyn/cm
Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me kekahi mau mea hoʻoheheʻe, ʻo ka wai hoʻonā he hana ma luna. ʻO ke aniani kiʻekiʻe. Hana paʻa, hoʻololi ka solubility me ka viscosity, ka haʻahaʻa o ka viscosity, ʻoi aku ka nui o ka solubility.
Loaʻa i ka HPMC nā hiʻohiʻona o ka hiki ke mānoanoa, ka paʻakai paʻakai, ka paʻa o ka PH, ka mālama ʻana i ka wai, ke kūpaʻa dimensional, ka waiwai hana kiʻiʻoniʻoni maikaʻi loa, a me ka laulā o ke kūpaʻa enzyme, dispersibility a me ka cohesiveness.
5, ke kumu nui
Hoʻohana nui ʻia ka HPMC papa hana ma ke ʻano he dispersant i ka hana ʻana o ka polyvinyl chloride, a ʻo ia ka mea kōkua nui no ka hoʻomākaukau ʻana i ka PVC ma o ka polymerization suspension. Eia kekahi, hiki ke hoʻohana ʻia e like me ka mānoanoa, stabilizer, emulsifier, excipient, a me ka mea mālama 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 textile a me ke kala, seramika, pepa. , cosmetics, etc. , film forming agent, etc. ʻO ka noi ʻana i nā resins synthetic hiki ke hana i nā huahana i loaʻa i nā ʻano o nā ʻāpana maʻamau a me ka wehe, kūpono i ka gravity kikoʻī a me ka hana hoʻoponopono maikaʻi loa, no laila ke hoʻololi nei i ka gelatin a me ka polyvinyl alcohol e like me nā dispersants.
ʻEono hana hoʻoheheʻe:
（1）. E lawe i ka nui o ka wai wela i makemake ʻia, e hoʻokomo i loko o kahi pahu a wela iā ia ma luna o 80 ° C, a hoʻohui mālie i kēia huahana ma lalo o ka hoʻoulu ʻana. Ke lana nei ka cellulose ma ka ʻili wai i ka wā mua, akā ua hoʻopuehu mālie ʻia e hana i kahi slurry like. Hoʻoluʻu ʻia ka hopena i ka wā e hoʻoulu ai.
（2）. ʻO kahi ʻē aʻe, e wela i ka 1/3 a i ʻole 2/3 o ka wai wela ma luna o 85 ° C, e hoʻohui i ka cellulose e loaʻa ai kahi slurry wai wela, a laila e hoʻohui i ke koena o ka wai anuanu, e hoʻomau i ka hoʻoulu ʻana, a hoʻomaha i ka hui ʻana.
（3）. Maikaʻi ka mesh o ka cellulose, a aia ia ma ke ʻano he mau ʻāpana liʻiliʻi i loko o ka pauka i hoʻoulu ʻia, a hemo koke i ka wā e hui ai i ka wai e hana i ka viscosity i koi ʻia.
（4）. E hoʻohui mālie a me ke kaulike i ka cellulose ma ka lumi wela, me ka hoʻoulu ʻana a hiki i ka hoʻokumu ʻana o kahi hopena ʻike.
