ʻO ka Hydroxypropyl methylcellulose (HPMC no ka pōkole) kahi ether i hui nui ʻia, he polymer wai-soluble non-ionic, a hoʻohana nui ʻia i ka meaʻai, lāʻau lapaʻau, ʻoihana kemika o kēlā me kēia lā, ka uhi ʻana, ka hopena polymerization a me ke kūkulu ʻana e like me ka hoʻokuʻu dispersion, thickening, emulsifying, stabilizing a me nā adhesives, a aia kahi hakahaka nui ma ka mākeke kūloko.
Hoʻohana nui ʻia ʻo Hydroxypropyl methylcellulose i ka ʻoihana kūkulu hale ma ke ʻano he mea hana kiʻiʻoniʻoni, mea hoʻopaʻa, mea hoʻolaha, mea hoʻopaʻa, mea mānoanoa, mea hoʻolaha wai, a me nā mea ʻē aʻe, a ua lilo ia i huahana hōkū i huki i ka manaʻo mai kona hoʻokuʻu ʻia ʻana ma ka laina.
ʻO ka Hydroxypropylmethylcellulose
Inoa piha ma ka ʻōlelo Pelekania: Hydroxypropyl Methyl Cellulose Pōkole ma ka ʻōlelo Pelekania: HPMC
Ma muli o nā waiwai maikaʻi loa o HPMC e like me ka thickening, emulsification, film forming, protective colloid, making makū, adhesion, enzyme resistance and metabolic inertness, ua hoʻohana nui ʻia ia i nā coatings, polymerization reactions, building materials, aila manufacturing, textiles, food, medicine, daily-use ceramics, electronic devices and agricultural seeds and other departments.
nā mea hana hale
I nā mea kūkulu hale, hoʻohui pinepine ʻia ʻo HPMC a i ʻole MC i ka sima, ka mortar, a me ka mortar e hoʻomaikaʻi i nā waiwai kūkulu a me ka paʻa ʻana o ka wai.
Hiki ke hoʻohana ʻia e like me:
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.
Mea hoʻopili no nā tile seramika
Nā ʻāpana HPMC 15.3

Hoʻohana ʻia i loko o ka sima i hoʻopaʻa ʻia me nā piliki inorganic, nā tile, nā pōhaku a i ʻole ka sima:
HPMC (kekelē hoʻopuehu 1.3) 0.3 ʻāpana
ʻĀpana sima Cattelan 100
One Silica 50 ʻāpana

Hoʻohana ʻia ma ke ʻano he mea hoʻohui mea kūkulu sima ikaika kiʻekiʻe:
ʻĀpana sima Cattelan 100

ʻOihana pena
I ka ʻoihana pena, hoʻohana nui ʻia ʻo HPMC i ka pena latex a me nā ʻāpana pena resin wai-soluble e like me ka mea hana kiʻiʻoniʻoni, thickener, emulsifier a me stabilizer.
ʻO ka Polymerization Hoʻokuʻu ʻia o PVC
ʻO ke kahua me ka hoʻohana nui ʻana o nā huahana HPMC ma koʻu ʻāina ʻo ia ka polymerization suspension o vinyl chloride. I ka polymerization suspension o vinyl chloride, hoʻopilikia pololei ka ʻōnaehana hoʻolaha i ka maikaʻi o ka huahana PVC resin a me kāna hana a me nā huahana; hiki iā ia ke hoʻomaikaʻi i ke kūpaʻa wela o ka resin a kāohi i ka hoʻolaha nui o ka ʻāpana (ʻo ia hoʻi, hoʻoponopono i ka density o PVC). ʻO ka nui o HPMC no 0.025% ~ 0.03 o ka % output PVC.
ʻO ka resin PVC i hoʻomākaukau ʻia e ka HPMC kiʻekiʻe, me ka hōʻoia ʻana e kūlike ka hana me ke kūlana aupuni, he mau waiwai kino maikaʻi hoʻi, nā ʻano ʻāpana maikaʻi loa a me ke ʻano rheological hoʻoheheʻe maikaʻi loa.
ʻoihana ʻē aʻe
ʻO nā ʻoihana ʻē aʻe e pili nui ana i nā mea hoʻonani, ka hana ʻaila, nā detergents, nā keramika hale a me nā ʻoihana ʻē aʻe.
wai hoʻoheheʻe ʻia
ʻO HPMC kekahi o nā polymers wai-soluble, a pili kona solubility wai i ka ʻike o ka hui methoxyl. Ke haʻahaʻa ka ʻike o ka hui methoxyl, hiki ke hoʻoheheʻe ʻia i loko o ka alkali ikaika a ʻaʻohe ona wahi gelation thermodynamic. Me ka hoʻonui ʻia o ka ʻike methoxyl, ʻoi aku ka maʻalahi o ka pehu ʻana o ka wai a hiki ke hoʻoheheʻe ʻia i loko o ka alkali dilute a me ka alkali nāwaliwali. Ke ʻoi aku ka nui o ka methoxyl ma mua o 38C, hiki ke hoʻoheheʻe ʻia i loko o ka wai, a hiki ke hoʻoheheʻe ʻia i loko o nā hydrocarbons halogenated. Inā hoʻohui ʻia ka waikawa periodic i ka HPMC, e hoʻopuehu koke ʻo HPMC i loko o ka wai me ka ʻole o ka hana ʻana i nā mea caking insoluble. ʻO ke kumu nui o kēia ma muli o ka ʻoiaʻiʻo he mau hui dihydroxyl ka waikawa periodic ma ke kūlana ortho ma ka glycogen i hoʻopuehu ʻia.
