ʻO ke kūlana kiʻekiʻe a me ka paʻa o ka hana mīkini o ka plastering mortar ke kumu nui o ka hoʻomohala ʻana, a ʻo ka cellulose ether, ʻo ia ka mea hoʻohui kumu o ka plastering mortar, i mea hiki ʻole ke hoʻololi.Cellulose eteraLoaʻa nā hiʻohiʻona o ka nui o ka paʻa ʻana o ka wai a me ka waiwai wīwī maikaʻi, a kūpono loa no ka mīkinikūkulu haleo ka hamo hamo.
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 hoʻoheheʻe mīkini. ʻoi aku ma mua o 93%. ʻO ke kiʻekiʻe o ka paʻa ʻana o ka wai o ka pahū, ʻoi aku ka liʻiliʻi o ke kahe 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 ke kiʻekiʻepaʻa waiuku.
ʻO ka hoʻopalapala ʻana i ka mortar 2h ka pau ʻole
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 hoʻokō ʻia ka hoʻokolohua hoʻokolohua 2h me nā viscosities o 50,000, 100,000, 150,000, a me 200,000. Hiki ke ʻike ʻia e like me ka piʻi ʻana o ka viscosity o cellulose ether, e emi mālie ka 2h o ka lilo 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 ka wehe ʻana i ka hamomanawa
Ma hope o kaka hamo hamoua kāpīpī ʻia ma ka paia, ma muli o ka hoʻoheheʻe 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, kahi e hoʻopili ai i ke kūkulu pae ʻana ma hope, no laila. pono e kālailai i ka manawa hoʻonohonoho o ka mortar. 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 me 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. ʻO ia hoʻi, ʻoi aku ka kiʻekiʻe o ka viscosity o cellulose ether, ʻoi aku ka nui o ke kūʻē ʻana o ka mortar a ʻoi aku ka nui o ka lole a me ka waimaka ma nā mea hana. No laila, no ka hana mechanized o ka plastering mortar, ʻoi aku ka maikaʻi o ka viscosity haʻahaʻa o cellulose ether.
ʻO ke kūpaʻa ʻana o ka hamo ʻana i ka hamo
Ma hope o ka pāpaʻi ʻia ʻana o ka pāpaʻi ma ka paia, inā ka sag kū'ē o kamokaʻAʻole maikaʻi, e hāʻule a paheʻe paha ka pahū, e hoʻopilikia nui i ka palahalaha o ka pahū, e hoʻopilikia nui i ka hana hope. No laila, pono e loaʻa i ka mortar maikaʻi ka thixotropy maikaʻi loa a me ke kūpaʻa sag. Ua ʻike ʻia 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 hana kēia mau ʻōhū 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.
ʻO ka hoʻonohonoho ʻana o nā mea mīkini kanaka ke kumu nui o ke kūkulu ʻana i ka mīkini, a ʻo ka maikaʻi o ka mortar ka mea nui loa. Ma ka hoʻohana wale ʻana i ka cellulose ether kūpono e hiki ai i nā waiwai o ka mortar ke hoʻokō i nā pono o ka hoʻoulu ʻana i ka mīkini.
