Cellulose etera Loaʻa iā ia nā pono penei:
ʻO ka mea mua, e hoʻoponopono i ka haʻahaʻa o ka ea, ke ʻoi aku ka haʻahaʻa o waho ma mua o ka haʻahaʻa kūpono o ka plaster plaster, no ka mea, ʻoi aku ka kiʻekiʻe o ke kaomi mahu o waho ma mua o kona kaomi mahu, hoʻoikaika i ka hana kūloko o ka adsorption o ka wai, i mea e hoʻopaneʻe ai i ka piʻi ʻana o ka wai. haʻahaʻa; Ke emi ka haʻahaʻa o waho ma mua o ka haʻahaʻa e pili ana i ka gypsum plastered, ʻoi aku ka haʻahaʻa o ke kaomi mahu o waho ma mua o kona kaomi mahu, e koi ana i ka hoʻoheheʻe ʻana o nā molekole wai i loko.

ʻO ka lua, ʻo ka hoʻopaneʻe ahi maikaʻi. ʻO ke kaumaha molecular o ka gypsum dihydrous he 172, a ʻo ke kaumaha o ka wai he 18. Ke hālāwai ka hale o 100m2 i ke ahi, ke piʻi ka mahana i 110 ℃ a i luna, e hoʻokuʻu koke ka gypsum dihydrous i ka wai aniani i loko o ka semihydrous gypsum a laila hoʻololi hou. i loko o ka gypsum anhydrous, hiki ke hoʻokuʻu i 560kg wai. Hiki i ka wai ke komo i ka wela nui ma ke kaʻina evaporation. Hiki iā ia ke pale maikaʻi i ka piʻi wikiwiki ʻana o ka lumi wela a hoʻomaikaʻi i nā manawa e pakele ai.
ʻO ke kolu, ka mālama ʻana i ka ʻōmaʻomaʻo. ʻO Gypsum ma hope o ka mālama ʻole ʻana, ʻaʻole i loko o nā mea haumia hiki ke hoʻohana ʻia, ka hoʻohana ʻana i nā mea gel inorganic, nā mea hoʻohui i nā huahana mālama kaiapuni, i hana ʻia me ka māmā plaster gypsum ʻaʻole e hoʻokuʻu i ka formaldehyde a me nā mea ʻino ʻē aʻe, ka palekana o ka ʻōmaʻomaʻo, palekana a hoʻomaha.

ʻO ka plastering gypsum me ka cellulose ether ka nui o nā ʻano penei:
1, hana maikaʻi: ʻoki maʻalahi, maʻalahi, hiki ke hoʻoheheʻe ʻia, me ka plasticity.
2, hoʻomaikaʻi i ka nui o ka hoʻopili ʻana i ka mortar plaster: i hoʻohālikelike ʻia me ka cellulose ether like, piʻi nui ka nui o ka uhi ʻana.
3, ʻoi aku ka maikaʻi o ka anti-droop hana: ʻaʻole kahe ka papa mānoanoa e ʻoki ana i ka hana hoʻokahi, ʻoi aku ma mua o ʻelua mau manawa (ʻoi aku ma mua o 3cm) ʻaʻole hāʻule ka ʻōpala, maikaʻi ka plasticity.

5, paʻa ikaika: kūpono no nā ʻano kumu gypsum āpau, e hoʻemi i ka wā kahiko o ka gypsum, e hoʻemi i ka nui o ka hoʻomaloʻo ʻana, ʻaʻole maʻalahi ka pā i ka pahu pahu, haki.
6, kahua noi a me ka nui: māmā lalo plaster gypsum, ʻōlelo ʻia ʻo 0.18% - 0.25%.
ʻO ka plastering gypsum me ka cellulose ether i hana ʻia i ka pulupulu hoʻomaʻemaʻe kiʻekiʻe e ka etherification reaction, non-ionic cellulose ether, nā waiwai kino paʻa, ʻaʻole e hana i ka hopena kemika me nā mea maka a hana i kekahi mau mea pōʻino, pili kaiapuni, ʻaʻohe hopena i ke olakino kanaka, i ka plastering gypsum he 'ano o ka 'ōmaʻomaʻo ikehu ho'ōla additives, KIMA i mau i ka manaʻo o ka 'ōmaʻomaʻo kaiapuni palekana a me ka ikehu mālama 'ia i loko o ka hui 'oihana a me ka hooponopono ana, ke kākoʻo nei makou i ka hoʻomohala 'ana, ma ka pane ana i ke kahea aupuni, omaomao mauna he gula a me ke kala. mauna, e hoʻohana ʻo KIMA i nā huahana cellulose ether maikaʻi aʻe e kōkua i ke ao nei e hana i ka pale ʻōmaʻomaʻo kaiapuni i loko o ka pā hale i loko.
