HPMC ma 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:
1.Ceramic tile adhesive
(1) He mea maʻalahi ke hoʻomaloʻo i ka hui ʻana i nā mea kanu, ʻaʻole e hua i nā ʻōpala, hoʻomaikaʻi i ka wikiwiki o ka noi, hoʻomaikaʻi i ka hana hana, mālama i ka manawa hana, hoʻemi i ke kumukūʻai o ka hana.
(2) Ma ka hoʻolōʻihi ʻana i ka manawa wehe, hoʻomaikaʻi i ka pono tile, a hāʻawi i ka hopena adhesion maikaʻi loa.

2. ʻO ka pāpaʻi sima
(1) E hoʻomaikaʻi i ka kūlike, e maʻalahi i ka mortar i ka trowel coating, i ka manawa like e hoʻomaikaʻi i ka anti-hanging, hoʻonui i ka wai a me ka pumping, hoʻomaikaʻi i ka hana pono.

(1) E hoʻomaikaʻi i ka kūlike, e maʻalahi i ka mortar i ka trowel coating, i ka manawa like e hoʻomaikaʻi i ka anti-hanging, hoʻonui i ka wai a me ka pumping, hoʻomaikaʻi i ka hana pono.
(2) ʻO ka paʻa wai kiʻekiʻe, hoʻolōʻihi i ka manawa hoʻokomo o ka mortar, hoʻomaikaʻi i ka hana pono, kūpono i ka hydration a me ka paʻa ʻana o ka mortar e hana i ka ikaika mechanical kiʻekiʻe.
(3) E hoʻopaʻa i ka kūlike o ka like ʻana o ka mortar, ka hoʻokumu ʻana i kahi uhi uhi kūpono.

4. ʻO ka pā pōhaku
(1) Hoʻonui i ka viscosity o ka masonry surface, hoʻonui i ka paʻa wai, hoʻomaikaʻi i ka ikaika o ka mortar.
(2) Hoʻonui i ka lubricity a me ka plasticity, hoʻomaikaʻi i ke kūkulu ʻana; ʻO ka mortar i hoʻomaikaʻi ʻia e cellulose ether ʻoi aku ka maʻalahi o ke kūkulu ʻana, mālama i ka manawa hana a hoʻemi i ke kumu kūʻai.
(3) ʻo ka cellulose ether, ʻoi aku ka nui o ka mālama ʻana i ka wai, kūpono ia no ka wai kiʻekiʻe.

5. Pāpā hui hoʻopiha
(1) Paʻa wai maikaʻi, hoʻolōʻihi i ka manawa wehe, hoʻomaikaʻi i ka hana pono. ʻO ka lubricant kiʻekiʻe, maʻalahi ka hui ʻana.
(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 hoʻohaʻahaʻa 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 ʻana o ka ʻili.

8.Wallpaper pauka
(1) wikiwiki e hoʻoheheʻe me ka ʻole o nā lumps, maikaʻi ia 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.pahu 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.
