Hoʻokumu HPMC i ka hale a me ka pena

ʻO ka Hydroxypropyl methylcellulose (HPMC no ka pōkole) he mea koʻikoʻi i hui pū ʻia, ʻo ia ka polymer non-ionic wai-soluble, a hoʻohana nui ʻia i ka meaʻai, ka lāʻau lapaʻau, ka ʻoihana kemika i kēlā me kēia lā, ka uhi ʻana, ka hopena polymerization a me ke kūkulu ʻana e like me ka dispersion suspension, thickening, emulsifying, stabilizing a me nā adhesives, etc., a aia kahi ākea nui ma ka mākeke kūloko.

No ka mea he mau waiwai maikaʻi loa ka HPMC e like me ka mānoanoa, emulsification, kiʻiʻoniʻoni, pale colloid, ka paʻa ʻana o ka moisture, adhesion, enzyme resistance a me ka metabolic inertness, ua hoʻohana nui ʻia i nā coatings, polymerization reactions, building materials, oil production, textiles, food, medicine, ʻO nā seramika hoʻohana i kēlā me kēia lā, nā mea uila a me nā hua mahiʻai a me nā keʻena ʻē aʻe.

I nā mea kūkulu hale, hoʻohui pinepine ʻia ʻo HPMC a i ʻole MC i ka sima, ka pahū, a me ka palaki e hoʻomaikaʻi i ke kūkulu ʻana a me nā waiwai paʻa wai.

Hiki ke hoʻohana ʻia ka HPMC ma:

1).ʻO ka mea hoʻopili a me ka mea hoʻoheheʻe no ka lipine pili gypsum;

2).ʻO ka hoʻopaʻa ʻana i nā pōhaku lepo, nā tile a me nā kumu;

3).stucco i hoʻopaʻa ʻia i ka papa pōhaku;

4).ʻO ka pāpaʻi hoʻoheheʻe ʻia ma muli o ka sima;

5).Ma ke ʻano o ka pena a me ka wehe ʻana i ka pena.

ʻO ke one silica 50 ʻāpana

50 hapa o ka wai

Hoʻohana ʻia ma ke ʻano he mea hoʻohui hale sima ikaika kiʻekiʻe:

Cattelan sima 100 hapa

ʻoihana pena

I ka ʻoihana pena, hoʻohana nui ʻia ʻo HPMC i ka pena latex a me nā ʻāpana pena resin i hoʻoheheʻe ʻia i ka wai ma ke ʻano he mea hana kiʻiʻoniʻoni, mānoanoa, emulsifier a me stabilizer.

Hoʻokuʻu Polymerization o PVC

ʻO ka māla me ka nui o ka hoʻohana ʻana i nā huahana HPMC i koʻu ʻāina ʻo ia ka polymerization hoʻokuʻu o vinyl chloride.I ka polymerization hoʻokuʻu o ka vinyl chloride, pili pono ka ʻōnaehana dispersion 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 hoʻomalu i ka hāʻawi ʻana i ka nui o nā ʻāpana (ʻo ia hoʻi, hoʻoponopono i ka density o PVC).ʻO ka nui o nā helu HPMC no 0.025% ~ 0.03% o ka puka PVC.

ʻO ka resin PVC i hoʻomākaukau ʻia e ka HPMC kiʻekiʻe, me ka hōʻoia ʻana i ka hoʻokō ʻana o ka hana i ke kūlana ʻāina, loaʻa nō hoʻi nā waiwai kino maikaʻi, nā hiʻohiʻona ʻāpana maikaʻi a me nā ʻano hoʻoheheʻe rheological maikaʻi loa.

Oʻoihana ʻē aʻe

ʻO nā ʻoihana ʻē aʻe ka nui o nā mea hoʻonaninani, ka hana ʻaila, nā mea holoi, nā seramika hale a me nā ʻoihana ʻē aʻe.

ʻO HPMC kekahi o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, a pili kona ʻano wai i ka ʻike o ka hui methoxyl.Ke haʻahaʻa ka ʻike o ka hui methoxyl, hiki ke hoʻoheheʻe ʻia i ka alkali ikaika a ʻaʻohe wahi thermodynamic gelation.Me ka hoʻonui o ka methoxyl maʻiʻo, ʻoi aku ka maʻalahi i ka pehu wai a hiki ke hoʻoheheʻe ʻia i ka alkali dilute a me ka alkali palupalu.Ke hoʻoheheʻe ʻia ka methoxyl ma kahi o 38C, hiki ke hoʻoheheʻe ʻia i ka wai, a hiki ke hoʻoheheʻe ʻia i loko o nā hydrocarbons halogenated.Inā hoʻohui ʻia ka ʻakika manawaleʻa i ka HPMC, e hoʻopuehu koke ʻo HPMC i ka wai me ka ʻole o ka hana ʻana i nā mea hiki ke hoʻoheheʻe ʻia.ʻO ka mea nui kēia ma muli o ka loaʻa ʻana o ka waika periodic i nā pūʻulu dihydroxyl i ke kūlana ortho ma ka glycogen dispersed.
