He hana ma luna nā hopena wai. ʻIke maopopo kiʻekiʻe, hana paʻa, mahana gel o nā huahana me nā kikoʻī like ʻole
ʻOkoʻa, loli ka solubility me ka viscosity, ʻo ka haʻahaʻa o ka viscosity, ʻo ka nui o ka solubility, ʻo ka hana o nā kikoʻī like ʻole o ka hydroxypropyl methylcellulose (HPMC) he mau ʻokoʻa, ʻaʻole i hoʻopilikia ʻia ka hopena waiwai PH o ka hoʻoheheʻe ʻana o ka hydroxypropyl methylcellulose (HPMC) i ka wai.
08. Me ka emi ʻana o ka nui o ka methoxyl, piʻi aʻe ke kiko gel, emi iho ka solubility wai, a emi pū ka hana o ka ʻili o ka hydroxypropyl methylcellulose (HPMC).
09. Loaʻa i ka Hydroxypropyl methylcellulose (HPMC) ka hiki ke mānoanoa, ke kūpaʻa paʻakai, ka pauka lehu haʻahaʻa, ke kūpaʻa PH, ka paʻa wai, ke kūpaʻa dimensional, ka waiwai hana kiʻiʻoniʻoni maikaʻi loa, a me ka laulā o ke kūpaʻa enzyme, nā ʻano hoʻopuehu e like me ke kāne a me ka hoʻopili ʻana.
ʻEkolu, nā ʻano hydroxypropyl methylcellulose (HPMC):
Hoʻohui ka huahana i nā waiwai kino a me nā kemika he nui e lilo i huahana kū hoʻokahi me nā hoʻohana he nui, a penei nā waiwai like ʻole:
(1) Paʻa wai: Hiki iā ia ke paʻa i ka wai ma luna o nā ʻili porous e like me nā papa sima pā a me nā piliki.
(2) Hoʻokumu ʻia ʻana o ka ʻili: Hiki iā ia ke hana i kahi ʻili moakaka, paʻakikī a palupalu me ke kūpaʻa ʻaila maikaʻi loa.
(3) Ka hoʻoheheʻe ʻana o ka mea ola: Hiki ke hoʻoheheʻe ʻia ka huahana i loko o kekahi mau mea hoʻoheheʻe organik, e like me ka ethanol/wai, propanol/wai, dichloroethane, a me kahi ʻōnaehana hoʻoheheʻe i haku ʻia me ʻelua mau mea hoʻoheheʻe organik.
(4) Gelation Thermal: Ke hoʻomehana ʻia ka hopena wai o ka huahana, e hana ia i gel, a e lilo hou ka gel i hana ʻia i hopena ma hope o ka hoʻomaʻalili ʻana.
(5) Hana ʻili: E hoʻolako i ka hana ʻili i loko o ka hopena e hoʻokō ai i ka emulsification a me ke colloid pale e pono ai, a me ka hoʻopaʻa ʻana o ka pae.
(6) Hoʻokuʻu ʻia: Hiki iā ia ke pale i ka ua ʻana o nā ʻāpana paʻa, a pēlā e pale ai i ka hoʻokumu ʻia ʻana o ka sediment.
(7) Colloid pale: hiki iā ia ke pale i nā kulu a me nā ʻāpana mai ka hui pū ʻana a i ʻole ka hoʻopili ʻana.
(8) Hoʻopili: Hoʻohana ʻia ma ke ʻano he mea hoʻopili no nā pigments, nā huahana paka, a me nā huahana pepa, he hana maikaʻi loa ia.
(9) Ka hoʻoheheʻe ʻia ʻana o ka wai: Hiki ke hoʻoheheʻe ʻia ka huahana i loko o ka wai ma nā ʻano like ʻole, a ʻo kona nui kiʻekiʻe loa e kaupalena wale ʻia e ka viscosity.
(10) ʻAʻohe ionic inertness: ʻO ka huahana he non-ionic cellulose ether, ʻaʻole ia e hui pū me nā paʻakai metala a i ʻole nā iona ʻē aʻe e hana i nā precipitates insoluble.
(11) Paʻa o ke kumu waikawa: kūpono no ka hoʻohana ʻana i loko o ka pae o PH3.0-11.0.
(12) ʻAʻohe ʻono a ʻala ʻole, ʻaʻole i hoʻopilikia ʻia e ka metabolism; i hoʻohana ʻia e like me nā mea hoʻohui meaʻai a me nā lāʻau lapaʻau, ʻaʻole lākou e metabolized i ka meaʻai a ʻaʻole e hāʻawi i nā calorie.
4. Ke ʻano hoʻoheheʻe ʻana o Hydroxypropyl methylcellulose (HPMC):
Ke hoʻohui pololei ʻia nā huahana hydroxypropyl methylcellulose (HPMC) i ka wai, e hoʻopili lākou a laila e hoʻoheheʻe, akā lohi loa a paʻakikī kēia hoʻoheheʻe ʻana. Aia ʻekolu mau ʻano hoʻoheheʻe i manaʻo ʻia ma lalo nei, a hiki i nā mea hoʻohana ke koho i ke ʻano kūpono loa e like me kā lākou hoʻohana ʻana:
1. Ke ʻano wai wela: ʻOiai ʻaʻole hoʻoheheʻe ʻia ka hydroxypropyl methylcellulose (HPMC) i ka wai wela, hiki ke hoʻopuehu like ʻia ke kahua mua o ka hydroxypropyl methylcellulose (HPMC) i ka wai wela, a laila ke hoʻomaʻalili ʻia, ʻekolu Ua wehewehe ʻia kahi ʻano maʻamau penei:
1). E hoʻokomo i ka nui o ka wai wela e pono ai i loko o ka ipu a hoʻomehana iā ia a hiki i kahi o 70°C. E hoʻohui mālie i ka hydroxypropyl methylcellulose (HPMC) ma lalo o ka hoʻoulu mālie ʻana, hoʻomaka ka hydroxypropyl methylcellulose (HPMC) e lana ma luna o ka wai, a laila e hana mālie i kahi slurry, e hoʻomaʻalili i ka slurry ma lalo o ka hoʻoulu ʻana.
2). E hoʻomehana i ka 1/3 a i ʻole 2/3 (ka nui e pono ai) o ka wai i loko o ka ipu a hoʻomehana iā ia i 70°C. Wahi a ke ʻano o 1), e hoʻopuehu i ka hydroxypropyl methylcellulose (HPMC) e hoʻomākaukau i ka slurry wai wela. A laila e hoʻohui i ke koena o ka wai anuanu a i ʻole ka wai hau i loko o ka ipu, a laila e hoʻohui i ka slurry wai wela hydroxypropyl methylcellulose (HPMC) i ʻōlelo ʻia ma luna i ka wai anuanu, a hoʻoulu, a laila e hoʻomaʻalili i ka hui ʻana.
3). E hoʻohui i ka 1/3 a i ʻole 2/3 o ka nui o ka wai e pono ai i loko o ka ipu a hoʻomehana iā ia i 70°C. Wahi a ke ʻano o 1), e hoʻopuehu i ka hydroxypropyl methylcellulose (HPMC) e hoʻomākaukau i ka slurry wai wela; A laila hoʻohui ʻia ke koena o ka wai anuanu a i ʻole ka wai hau i ka slurry wai wela a hoʻomaʻalili ʻia ka hui ʻana ma hope o ka hoʻoulu ʻana.
2. Ke ʻano hoʻohuihui pauka: ʻO nā ʻāpana pauka hydroxypropyl methylcellulose (HPMC) a me ka nui like a ʻoi aku paha o nā mea pauka ʻē aʻe e hoʻopuehu piha ʻia e ka hui maloʻo, a laila hoʻoheheʻe ʻia i loko o ka wai, a laila hiki ke hoʻoheheʻe ʻia ka hydroxypropyl methylcellulose Base cellulose (HPMC) me ka ʻole o ka hoʻohuihui ʻana. 3. Ke ʻano hoʻomaʻū ʻana o ka mea hoʻoheheʻe organik: pre-disperse a i ʻole ka hydroxypropyl methylcellulose pulu (HPMC) me nā mea hoʻoheheʻe organik e like me ka ethanol, ethylene glycol a i ʻole ka ʻaila, a laila hoʻoheheʻe ʻia i loko o ka wai. I kēia manawa, hiki ke hoʻoheheʻe maʻalahi ʻia ka hydroxypropyl methylcellulose (HPMC).
5. Nā hoʻohana nui o ka hydroxypropyl methylcellulose (HPMC):
Hiki ke hoʻohana ʻia ʻo Hydroxypropyl methylcellulose (HPMC) ma ke ʻano he mea hoʻomānoanoa, mea hoʻolaha, mea hoʻohuihui a me ka mea hana kiʻiʻoniʻoni. Hiki ke hoʻohana ʻia kāna huahana papa ʻoihana i nā kemika o kēlā me kēia lā, nā mea uila, nā resins synthetic, ke kūkulu ʻana a me nā uhi ʻana.
1. Hoʻohuihui hoʻokuʻu:
I ka hana ʻana o nā resins synthetic e like me ka polyvinyl chloride (PVC), polyvinylidene chloride a me nā copolymers ʻē aʻe, hoʻohana pinepine ʻia ka polymerization suspension a pono e hoʻopaʻa i ka hoʻokuʻu ʻana o nā monomers hydrophobic i loko o ka wai. Ma ke ʻano he polymer wai-soluble, loaʻa i nā huahana hydroxypropyl methylcellulose (HPMC) ka hana ʻili maikaʻi loa a hana ma ke ʻano he mea pale colloidal, hiki ke pale pono i ka hōʻuluʻulu ʻana o nā ʻāpana polymer. Eia kekahi, ʻoiai ʻo hydroxypropylmethylcellulose (HPMC) he polymer wai-soluble, he mea hoʻoheheʻe iki ia i nā monomers hydrophobic a hoʻonui i ka porosity o nā monomers mai kahi i hana ʻia ai nā ʻāpana polymeric, i hiki ai iā ia ke hāʻawi i nā polymers me ka hiki ke wehe i nā monomers koena a hoʻonui i ka omo ʻana o nā plasticizers.
2. I ke kūkulu ʻana i nā mea hana hale, hiki ke hoʻohana ʻia ka hydroxypropyl methylcellulose (HPMC) no:
1). Mea hoʻopili a me ka mea hoʻopili no ka lipine hoʻopili i hoʻokumu ʻia i ka gypsum;
2). Ka hoʻopaʻa ʻana o nā piliki sima, nā tile a me nā kahua;
3). Stucco i hana ʻia ma ka plasterboard;
4). Pālaki kūkulu i hoʻokumu ʻia i ka sima;
5). Ma ke ʻano o ka pena a me ka mea wehe pena.
