HPMC i ke kukulu ana

ʻO ka Hydroxypropyl methyl cellulose HPMC he mea maʻamau polymer material cellulose ma ke ʻano he mea maka, ma o ke ʻano o ka hana kemika a hana ʻia me ka non-ionic cellulose ether.He pauka keʻokeʻo ʻona ʻole lākou, ʻono ʻole, ʻaʻohe mea ʻawaʻawa e hoʻonui ʻia i loko o kahi ʻoluʻolu colloid māmā a ʻeleʻele paha i loko o ka wai anuanu.Me ka mānoanoa, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gel, surface activity, moisture retention and colloidal protection, etc. Hydroxypropyl methyl cellulose HPMC, methyl cellulose MC hiki ke hoʻohana i nā mea kūkulu hale, ka ʻoihana uhi, resin synthetic, ʻoihana seramika, lāʻau lapaʻau, meaʻai, textile, mahiʻai, lāʻau kemika a me nā ʻoihana ʻē aʻe.

Nā waiwai o HPMC i hoʻohana ʻia i ke kūkulu ʻana
1. Paʻa wai
ʻO ka Hydroxypropyl methyl cellulose HPMC no ke kūkulu ʻana e pale i ka absorption nui o ka wai e ka substrate, a pono e hoʻopaʻa ʻia ka wai i loko o ka plaster i ka wā e pau ai ka paʻa ʻana o ka gypsum.Ua ikeia keia waiwai i ka wai paa, a ua like ia me ka viscosity o ka hale kūikawā hydroxypropyl methyl cellulose HPMC solution i loko o ka stucco, ʻoi aku ka kiʻekiʻe o ka viscosity o ka hopena, ʻoi aku ka kiʻekiʻe o ka paʻa wai.
Ke hoʻonui ʻia ka wai, hoʻemi ʻia ka nui o ka mālama ʻana i ka wai, no ka mea, ua hoʻoheheʻe ka wai i ka hana ʻana o ka hydroxypropyl methyl cellulose HPMC solution, ka hopena i ka emi ʻana o ka viscosity.
2. Sag kū'ē
ʻO kahi stucco hiki ke kahe a kau ʻia e hiki i ka mea hana ke hoʻopili i kahi uhi mānoanoa me ka ʻole o ke kahe kū pololei, ʻo ia hoʻi he thixotropic ka stucco ponoʻī, inā ʻaʻole ia e paheʻe i lalo i ka wā o ke kūkulu ʻana.
3. E ho'ēmi i ka viscosity, hana maʻalahi
Ma ka hoʻohui ʻana i nā ʻano like ʻole o ke kūkulu ʻana i nā huahana HPMC hydroxypropyl methyl cellulose, hiki ke loaʻa ka viscosity haʻahaʻa a me ka hana maʻalahi mai ka plaster gypsum, me ka hoʻohana ʻana i ka hale haʻahaʻa viscosity haʻahaʻa i hoʻolaʻa ʻia i ka hydroxypropyl methyl cellulose HPMC, ʻoi aku ka liʻiliʻi o ka viscosity a me ke kūkulu maʻalahi, akā naʻe, haʻahaʻa haʻahaʻa viscosity hale i hoʻolaʻa ʻia. ʻO ka hydroxypropyl methyl cellulose HPMC hiki ke mālama i ka wai he nāwaliwali, pono e hoʻonui i ka nui.
4. Ka nui o ka ulu ʻana o ka stucco
No ka paʻa paʻa o ka mortar maloʻo, ʻoi aku ka maikaʻi o ka hana ʻana i ka nui o ka mortar pulu kiʻekiʻe, hiki ke hoʻokō ʻia me ka hoʻohui ʻana i ka wai a me nā ʻōpū.Akā ʻo ka nui o ka wai a me nā ʻōpū e hōʻino i ka ikaika.

Hoʻohana HPMC i nā mea hana:

(3) ʻo ka cellulose ether, ʻoi aku ka nui o ka mālama ʻana i ka wai, kūpono ia no ka wai kiʻekiʻe.

5. Pākuʻi hui pū
(1) Paʻa wai maikaʻi, hoʻolōʻihi i ka manawa wehe, hoʻomaikaʻi i ka hana pono.ʻO ka lubricant kiʻekiʻe, maʻalahi ke hui.
(2) Ua hoʻomaikaʻi ʻia nā waiwai anti-shrinkage a me nā anti-cracking a ua hoʻomaikaʻi ʻia ka maikaʻi o ka ʻili o ka uhi.
(3) E hoʻomaikaʻi i ka hoʻopili ʻana o ka ʻili i hoʻopaʻa ʻia, e hāʻawi ana i kahi ʻano maʻalahi.

6.Self pae honua mea
(1) hāʻawi i ka viscosity, hiki ke hoʻohana ʻia e like me AIDS anti-settlement.
(2) Hoʻonui i ka paila ʻana o ka wai, hoʻomaikaʻi i ka pono o ka paving i ka lepo.
(3) E hoʻomalu i ka paʻa ʻana o ka wai a me ka emi ʻana, e hōʻemi i ka haki ʻana a me ka ʻoki ʻana o ka lepo.

7.Water ma muli o ka pena a me ka uhi
(1) E pale i ka ua paʻa, e hoʻolōʻihi i ka manawa pahu o ka huahana.
(2) Ke kūpaʻa olaola kiʻekiʻe a me ka launa maikaʻi me nā mea ʻē aʻe.
(3) E hoʻomaikaʻi i ka wai, hāʻawi i ka anti-splash maikaʻi, anti-drop a me ke kahe ʻana o ke kahe, e hōʻoia i ka hoʻopau maikaʻi loa.

8.Wallpaper pauka
(1) wikiwiki e hoʻoheheʻe me ka ʻole o nā lumps, kahi maikaʻi no ka hui ʻana.
(2) hāʻawi i ka ikaika pili kiʻekiʻe.

9.Extrusion molding sima pā
(1) loaʻa ka cohesiveness kiʻekiʻe a me ka lubricity, hoʻonui i ka hana hana o nā huahana extrusion.
(2) Hoʻomaikaʻi i ka ikaika ʻōmaʻomaʻo, hoʻoikaika i ka hopena hydration curing, hoʻonui i ka hua o ka huahana i hoʻopau ʻia.

10. ka paʻakai mua
ʻOi aku ka maikaʻi o ka paʻa ʻana o ka wai mortar ma mua o nā huahana maʻamau, e hōʻoia i ka hydration piha o nā mea cementitious inorganic, e pale nui i ka maloʻo wikiwiki ʻana ma muli o ka emi ʻana o ka ikaika paʻa, a me ka hoʻomaloʻo ʻana i ka shrinkage ma muli o ka haki ʻana.Loaʻa i ka HPMC kekahi hopena hoʻopili ea, nā huahana HPMC kūikawā premixed, ea entraining pono nui, ʻaʻahu a me nā puʻupuʻu liʻiliʻi, hiki ke hoʻomaikaʻi i ka ikaika a me ka nani o ka mortar premixed.ʻO nā huahana HPMC kūikawā premixed i kahi hopena lohi, hiki ke hoʻolōʻihi i ka manawa wehe o ka mortar premixed, hoʻemi i ka paʻakikī o ke kūkulu ʻana.
