Hydroxypropyl methylcellulose (HPMC)he ether non-ionic cellulose i hana ʻia mai ka cellulose material polymer maoli ma o ke ʻano o ka hana kemika. He pauda keʻokeʻo ʻaʻala ʻole, ʻono a ʻona ʻole e pehu ana i loko o ka wai anuanu a hiki i kahi hopena colloidal maʻemaʻe a haʻalulu iki paha. Loaʻa nā waiwai o ka mānoanoa, hoʻopaʻa, hoʻopuehu, emulsifying, hana kiʻiʻoniʻoni, hoʻopaneʻe, adsorbing, gelling, nā waiwai o ka ʻili, mālama i ka wai a me nā colloids pale. Hiki ke hoʻohana ʻia ka Hydroxypropyl methylcellulose, methylcellulose i nā mea kūkulu hale, ʻoihana uhi, resin synthetic, ʻoihana ceramics, lāʻau lapaʻau, meaʻai, textile, mahiʻai, kemika o kēlā me kēia lā a me nā ʻoihana ʻē aʻe.
ʻO ka noi nui o ka hydroxypropyl methylcellulose HPMC i nā mea kūkulu hale:
1 Hoʻopili ʻia i ka lepo lepo
①E hoʻomaikaʻi i ka like ʻole, e maʻalahi ka hoʻopili ʻana i ka plastering paste i ka trowel, hoʻomaikaʻi i ka pale ʻana i ka sag, hoʻomaikaʻi i ka wai a me ka pumpability, a hoʻomaikaʻi i ka hana pono.
②Ka paʻa wai kiʻekiʻe, hoʻolōʻihi i ka manawa kau o ka mortar, hoʻomaikaʻi i ka hana pono, a hoʻomaʻamaʻa i ka hydration a me ka paʻa ʻana o ka mortar e hana i ka ikaika mechanical kiʻekiʻe.
③ E hoʻomalu i ka hoʻokomo ʻana o ka ea e hoʻopau i nā māwae ma ka ʻili o ka uhi a hana i kahi ʻili maʻalahi.
2 ʻO nā mea hoʻopalapala hoʻoheheʻe ʻia ma ka Gypsum a me nā huahana gypsum
①E hoʻomaikaʻi i ka like ʻole, e maʻalahi ka hoʻopili ʻana i ka plastering paste i ka trowel, hoʻomaikaʻi i ka pale ʻana i ka sag, hoʻomaikaʻi i ka wai a me ka pumpability, a hoʻomaikaʻi i ka hana pono.
②Ka paʻa wai kiʻekiʻe, hoʻolōʻihi i ka manawa kau o ka mortar, hoʻomaikaʻi i ka hana pono, a hoʻomaʻamaʻa i ka hydration a me ka paʻa ʻana o ka mortar e hana i ka ikaika mechanical kiʻekiʻe.
③ E hoʻomalu i ka paʻa ʻana o ka mortar e ʻaʻahu a hana i kahi uhi ʻili kūpono.
3 Masonry mortar
①E hoʻonui i ka pili ʻana me ka ʻili pōhaku, hoʻonui i ka paʻa wai, a hoʻomaikaʻi i ka ikaika o ka mortar.
②E hoʻomaikaʻi i ka lubricity a me ka plasticity, a hoʻomaikaʻi i ka hana; ʻO ka mortar i hoʻomaikaʻi ʻia e cellulose ether e maʻalahi ke kūkulu ʻana, mālama i ka manawa hana a hoʻemi i ke kumukūʻai kūkulu.
③Ultra-kiʻekiʻe wai-hoʻopaʻa cellulose ether, kūpono no ka wai kiʻekiʻe-hoʻopaʻa pōhaku pōhaku.
4 pā hoʻohui hui
①Ka paʻa wai maikaʻi, hoʻolōʻihi i ka manawa wehe a hoʻomaikaʻi i ka hana pono. ʻO ka lubricant kiʻekiʻe, maʻalahi ka hui ʻana.
②E hoʻomaikaʻi i ka hoʻohaʻahaʻa ʻana a me ka pale ʻana, a hoʻomaikaʻi i ka maikaʻi o ka ʻili o ka uhi.
③E hoʻomaikaʻi i ka hoʻopili ʻana o ka ʻili paʻa a hāʻawi i kahi ʻano maʻalahi a maʻalahi.
5 Kile Adhesive
①Maʻalahi e maloʻo i ka hui ʻana i nā mea ʻai, ʻaʻohe lumps e hana ʻia, e hoʻonui ʻia ka wikiwiki o ka noi, e hoʻomaikaʻi ʻia ka hana hana, e mālama ʻia ka manawa hana, a e hoʻemi ʻia ke kumukūʻai hana.
②Ma ka hoʻonui ʻana i ka manawa wehe, hoʻomaikaʻi ia i ka pono o ka tiling a hāʻawi i ka hopena adhesion maikaʻi loa.
6 Nā mea papahele hoʻonanea ponoʻī
① Hāʻawi i ka viscosity a hiki ke hoʻohana ʻia ma ke ʻano he kōkua anti-settling.
②E hoʻonui i ka pumpability o ka wai a hoʻomaikaʻi i ka pono o ka paving.
③ E mālama i ka paʻa ʻana o ka wai a me ka emi ʻana e hōʻemi i nā māwae a me ka emi ʻana o ka lepo.
7 Pena wai
①E pale i ka ua paʻa a hoʻolōʻihi i ka manawa pahu o ka huahana. ʻO ke kūpaʻa olaola kiʻekiʻe a me ka launa maikaʻi me nā mea ʻē aʻe.
②E hoʻomaikaʻi i ka wai, hāʻawi i ke kūpaʻa splash maikaʻi, ka pale ʻana a me ka pae ʻana, a hōʻoia i ka hoʻopau maikaʻi ʻana o ka ʻili.
8 pepa pepa pepa
①E hoʻoheheʻe koke me ka ʻole agglomeration, kahi kūpono no ka hui ʻana.
② Hāʻawi i ka ikaika pili kiʻekiʻe.
9 Papa sima extruded
①He kiʻekiʻe adhesion a me ka lubricity, a hoʻonui i ka processability o nā huahana extruded.
②E hoʻomaikaʻi i ka ikaika ʻōmaʻomaʻo, hoʻoikaika i ka hydration a me ka hopena hoʻōla, a hoʻomaikaʻi i ka hua.
10 mau huahana HPMC no ka hamo i hoʻohui ʻia
ʻO kaHPMCʻoi aku ka maikaʻi o ka mālama ʻana o ka wai ma mua o nā huahana maʻamau i loko o ka mortar i hoʻomākaukau ʻia, e hōʻoia ana i ka hoʻomaʻemaʻe piha ʻana o nā mea cementitious inorganic, a pale nui i ka emi ʻana o ka ikaika paʻa ma muli o ka maloʻo nui ʻana a me ka haki ʻana ma muli o ka maloʻo ʻana. Loaʻa i ka HPMC kekahi hopena ea. ʻO nā huahana HPMC i hoʻohana kūikawā ʻia no ka mīkini paʻipaʻi mākaukau he kūpono, ʻaʻahu a me ka liʻiliʻi o ka ea-entrainment, hiki ke hoʻomaikaʻi i ka ikaika a me ka plastering o ka mortar mākaukau. ʻO ka huahana HPMC i hoʻohana kūikawā ʻia no ka mortar i hoʻomākaukau ʻia he hopena hoʻopaneʻe, hiki ke hoʻolōʻihi i ka manawa wehe o ka mortar i hoʻomākaukau ʻia a hoʻemi i ka paʻakikī o ke kūkulu ʻana. ʻO ka Hydroxypropyl methylcellulose (HPMC) he ether non-ionic cellulose i hana ʻia mai ka cellulose material polymer maoli ma o ke ʻano o ka hana kemika. He pauda keʻokeʻo ʻaʻala ʻole, ʻono a ʻona ʻole e pehu ana i loko o ka wai anuanu a hiki i kahi hopena colloidal maʻemaʻe a haʻalulu iki paha. Loaʻa nā waiwai o ka mānoanoa, hoʻopaʻa, hoʻopuehu, emulsifying, hana kiʻiʻoniʻoni, hoʻopaneʻe, adsorbing, gelling, nā waiwai o ka ʻili, mālama i ka wai a me nā colloids pale. Hiki ke hoʻohana ʻia ka Hydroxypropyl methylcellulose, methylcellulose i nā mea kūkulu hale, ʻoihana uhi, resin synthetic, ʻoihana ceramics, lāʻau lapaʻau, meaʻai, textile, mahiʻai, kemika o kēlā me kēia lā a me nā ʻoihana ʻē aʻe.
