Ka nui o ka paʻa ʻana o ka wai o ka hamo
ʻO ka nui o ka paʻa ʻana o ka wai o ka mortar plastering ke piʻi nei i ka wā o ka viscosity o cellulose ether mai 50,000 a 100,000, a he ʻano hoʻohaʻahaʻa i ka wā mai 100,000 a 200,000, ʻoiai ua hiki i ka nui o ka mālama ʻana i ka wai o cellulose ether no ka hoʻoulu ʻana i ka mīkini. ʻoi aku ma mua o 93%.ʻO ke kiʻekiʻe o ka paʻa ʻana o ka wai o ka mortar, ʻoi aku ka liʻiliʻi o ke kahe ʻana o ke koko.I ka wā o ka hoʻāʻo ʻana me ka mīkini hoʻoheheʻe ʻana i ka mīkini, ua ʻike ʻia i ka wā o ka paʻa ʻana o ka wai o ka cellulose ether ma lalo o 92%, ʻoi aku ka maikaʻi o ke kahe koko ma hope o ka waiho ʻia ʻana no kekahi manawa, a, i ka hoʻomaka ʻana o ka pīpī. , he mea maʻalahi loa ke ālai i ka paipu.No laila, i ka wā e hoʻomākaukau ai i ka mortar plastering kūpono no ka hana mechanized, pono mākou e koho i ka cellulose ether me ka nui o ka paʻa wai.
ʻO ka hamo ʻana i ka hamo 2h nalowale o ke kūlike
E like me nā koi o GB / T25181-2010 "Mākaukau Mixed Mortar", ʻo ka ʻelua mau hola e pono ai ka pohō o ka mortar plastering maʻamau ma lalo o 30%.Ua hoʻohana ʻia ka viscosity o 50,000, 100,000, 150,000, a me 200,000 no nā hoʻokolohua hoʻokolohua 2h.Hiki ke ʻike ʻia e like me ka piʻi ʻana o ka viscosity o cellulose ether, e emi mālie ka waiwai o ka 2h consistency loss of mortar, e hōʻike pū ana hoʻi i ka viscosity o cellulose ether ʻO ke kiʻekiʻe o ka waiwai, ʻoi aku ka maikaʻi o ka paʻa paʻa o ka mortar a ʻoi aku ka maikaʻi. hana anti-delamination o ka mortar.Eia nō naʻe, i ka wā o ka pīpī maoli ʻana, ua ʻike ʻia i ka wā o ka mālama ʻana i ka pae ma hope, no ka mea, ʻoi aku ka kiʻekiʻe o ka viscosity o cellulose ether, ʻoi aku ka nui o ka hui ʻana ma waena o ka mortar a me ka trowel, ʻaʻole kūpono i ke kūkulu ʻana.No laila, i ka hihia o ka hōʻoia ʻana ʻaʻole e hoʻopaʻa ʻia ka mortar a ʻaʻole delaminate, ʻoi aku ka haʻahaʻa o ka waiwai viscosity o ka cellulose ether, ʻoi aku ka maikaʻi.
ʻO nā hola wehe ʻana o ka hamo
Ma hope o ka hoʻopili ʻia ʻana o ka mortar plastering ma ka paia, ma muli o ke komo ʻana o ka wai o ka substrate o ka pā a me ka hoʻoheheʻe ʻana o ka wai ma luna o ka ʻili o ka mortar, e hoʻokumu ka mortar i kahi ikaika i loko o kahi manawa pōkole, e hoʻopilikia i ke kūkulu pae ʻana. .Ua kālailai ʻia ka manawa clotting.ʻO ka waiwai viscosity o cellulose ether aia ma ka laulā o 100,000 a 200,000, ʻaʻole loli nui ka manawa hoʻonohonoho, a he pilina pū kekahi me ka nui o ka mālama ʻana i ka wai, ʻo ia hoʻi, ʻoi aku ka kiʻekiʻe o ka paʻa wai, ʻoi aku ka lōʻihi. ka manawa hoʻonohonoho o ka pahū.
ʻO ka wai o ka hamo ʻana
ʻO ka lilo ʻana o nā mea hoʻoheheʻe ʻia he mea nui ia e pili ana i ka wai o ka mortar plastering.Ma lalo o ka lākiō wai-mea like, ʻoi aku ka kiʻekiʻe o ka viscosity o cellulose ether, ʻoi aku ka haʻahaʻa o ka waiwai o ka mortar., 'o ia ho'i ke ki'eki'e o ka viscosity o ka cellulose ether, 'oi aku ka nui o ke kū'ē'ana o ka mortar a me ka nui o ka lole ma luna o nā mea hana.No laila, ʻoi aku ka maikaʻi o ka viscosity haʻahaʻa o ka cellulose ether no ke kūkulu ʻana i ka mīkini palaki.
ʻO ke kūpaʻa ʻana o ka hamo ʻana i ka hamo
Ma hope o ka pīpī ʻia ʻana o ka pāpaʻi ma ka paia, inā ʻaʻole maikaʻi ke kūpaʻa ʻana o ka mortar, e hāʻule a paheʻe paha ka pahū, e hoʻopilikia nui i ka palahalaha o ka hamo, kahi e pilikia nui ai ka hana hope.No laila, pono e loaʻa i ka mortar maikaʻi ka thixotropy maikaʻi loa a me ka pale sag.Ua ʻike ka hoʻokolohua ma hope o ke kūkulu ʻia ʻana o ka cellulose ether me ka viscosity o 50,000 a me 100,000 i ka vertically, ʻaʻole i paheʻe nā tile i lalo, ʻoiai ʻo ka cellulose ether me ka viscosity o 150,000 a me 200,000 ʻaʻole i paheʻe.Ke kū pololei nei ke kihi, ʻaʻohe paheʻe.
Ka ikaika o ka hamo hamo
Me ka hoʻohana ʻana i 50,000, 100,000, 150,000, 200,000, a me 250,000 cellulose ethers e hoʻomākaukau ai i nā mea hoʻohālike o ka plastering mortar no ka hana mechanized, ua ʻike ʻia me ka piʻi ʻana o ka cellulose ether viscosity, ʻoi aku ka ikaika o ka waiwai o ka plastering mortar.ʻO kēia ke kumu no ka hana ʻana o ka cellulose ether i kahi hopena viscosity kiʻekiʻe i loko o ka wai, a e hoʻokomo ʻia ka nui o nā ea paʻa i ka wā o ka hui ʻana o ka mortar.Ma hope o ka paʻa ʻana o ka sima, e hoʻokumu ʻia kēia mau ʻōpū o ka ea i ka nui o nā lua, a laila e hōʻemi ana i ka waiwai ikaika o ka mortar.No laila, pono e hoʻokō i ka waiwai ikaika i koi ʻia e ka hoʻolālā ʻana i ka mortar plastering kūpono no ka hana mīkini, a pono ke koho ʻia kahi cellulose ether kūpono.
