Ua holomua nui ke kūkulu ʻana o ka mīkini palaki i nā makahiki i hala iho nei. Ua ulu pū ka mīkini palaki mai ka hui ponoʻī ʻana o ke kahua kuʻuna i ka mīkini palaki maloʻo a me ka mīkini palaki pulu maʻamau. ʻO kona ʻoi aku ka maikaʻi o ka hana a me ke kūpaʻa nā mea nui e hoʻolaha i ka hoʻomohala ʻana o ka mīkini palaki, a hoʻohana ʻia ka cellulose ether ma ke ʻano he mīkini palaki. He kuleana koʻikoʻi ko ka mea hoʻohui nui. Ma kēia hoʻokolohua, ma ka hoʻoponopono ʻana i ka mānoanoa a me ka paʻa ʻana o ka wai o ka cellulose ether, a ma o ka hoʻololi synthetic, ua aʻo ʻia nā hopena o nā ʻōkuhi hoʻokolohua e like me ka nui o ka paʻa ʻana o ka wai, ka nalowale o ke kūlike 2h, ka manawa wehe, ke kū'ē ʻana i ka sag, a me ke kahe o ka mīkini palaki ma ke kūkulu ʻana. ʻO ka mea hope loa, ua ʻike ʻia he mau ʻano o ka cellulose ether ka nui o ka paʻa ʻana o ka wai a me ka waiwai ʻōwili maikaʻi, a kūpono loa ia no ke kūkulu ʻana o ka mīkini palaki, a ua kūlike nā ʻōkuhi āpau o ka mīkini palaki i nā kūlana aupuni.
Ka nui o ka paʻa ʻana o ka wai o ka mortar palaki
ʻO ke ʻano o ka paʻa ʻana o ka wai o ka mortar plastering he ʻano piʻi i ka wā e piʻi ai ka viscosity o ka cellulose ether mai 50,000 a i 100,000, a he ʻano emi ia i ka wā mai 100,000 a i 200,000, ʻoiai ua hiki aku ka nui o ka paʻa ʻana o ka wai o ka cellulose ether no ka pīpī ʻana o ka mīkini ma mua o 93%. ʻO ke kiʻekiʻe o ka nui o ka paʻa ʻana o ka wai o ka mortar, ʻo ka emi ʻana o ke kahe ʻana o ke koko o ka mortar. I ka wā o ka hoʻokolohua pīpī ʻana me kahi mīkini pīpī mortar, ua ʻike ʻia i ka wā e emi ana ka nui o ka paʻa ʻana o ka wai o ka cellulose ether ma mua o 92%, ua maʻalahi ka mortar i ke kahe ʻana o ke koko ma hope o ke kau ʻia ʻana no kekahi manawa, a, i ka hoʻomaka ʻana o ka pīpī ʻana, he mea maʻalahi loa ke ālai i ka paipu. No laila, i ka wā e hoʻomākaukau ai i ka mortar plastering kūpono no ke kūkulu ʻana i ka mīkini, pono mākou e koho i ka cellulose ether me ka nui o ka paʻa ʻana o ka wai.
Ka nalowale o ke kūlike o ka palaki ʻana i ka mortar 2h
Wahi a nā koi o GB/T25181-2010 "Ready Mixed Mortar", ʻo ke koi ʻelua hola o ka nalowale ʻana o ke kūlike o ka mortar plastering maʻamau he emi ma mua o 30%. Ua hoʻohana ʻia ka viscosity o 50,000, 100,000, 150,000, a me 200,000 no nā hoʻokolohua nalowale kūlike 2h. Hiki ke ʻike ʻia i ka piʻi ʻana o ka viscosity o ka cellulose ether, e emi mālie ana ka waiwai nalowale kūlike 2h o ka mortar, e hōʻike ana hoʻi i ka viscosity o ka cellulose ether ʻO ke kiʻekiʻe o ka waiwai, ʻoi aku ka maikaʻi o ke kūpaʻa kūlike o ka mortar a ʻoi aku ka maikaʻi o ka hana anti-delamination o ka mortar. Eia 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 ua kiʻekiʻe loa ka viscosity o ka cellulose ether, ʻoi aku ka nui o ka cohesion ma waena o ka mortar a me ka trowel, ʻaʻole ia he mea kūpono i ke kūkulu ʻana. No laila, i ke ʻano o ka hōʻoia ʻana ʻaʻole e noho ka mortar a ʻaʻole e delaminate, ʻoi aku ka maikaʻi o ka haʻahaʻa o ka waiwai viscosity o ka cellulose ether.
Nā hola wehe o ka palaki ʻana i ka mortar
Ma hope o ka pīpī ʻia ʻana o ka mortar plastering ma ka paia, ma muli o ka omo ʻana o ka wai o ka substrate paia a me ka mahu ʻana o ka makū ma luna o ka ʻili o ka mortar, e hoʻokumu ka mortar i kahi ikaika i loko o kahi manawa pōkole, kahi e hoʻopilikia ai i ke kūkulu ʻana o ka pae ma hope. Ua kālailai ʻia ka manawa clotting. Aia ka waiwai viscosity o ka cellulose ether ma ka pae o 100,000 a 200,000, ʻaʻole loli nui ka manawa hoʻonohonoho, a he pilina pū kekahi me ka helu paʻa wai, ʻo ia hoʻi, ʻo ke kiʻekiʻe o ka helu paʻa wai, ʻoi aku ka lōʻihi o ka manawa hoʻonohonoho o ka mortar.
Ka wai o ka palaki ʻana i ka mortar
ʻO ka nalowale ʻana o nā lako pīpī e pili nui ana i ke kahe o ka mortar plastering. Ma lalo o ka lakio wai-mea like, ʻo ke kiʻekiʻe o ka viscosity o ka cellulose ether, ʻo ka haʻahaʻa o ka waiwai wai o ka mortar. , ʻo ia hoʻi, ʻo ke kiʻekiʻe o ka viscosity o ka cellulose ether, ʻoi aku ka nui o ke kū'ē o ka mortar a ʻoi aku ka nui o ka ʻaʻahu ʻana ma nā lako. No laila, no ke kūkulu ʻana o ka mortar plastering i hana ʻia me ka mīkini, ʻoi aku ka maikaʻi o ka viscosity haʻahaʻa o ka cellulose ether.
Ke kū'ē ʻana i ka palaki ʻana o ka mortar
Ma hope o ka pīpī ʻia ʻana o ka mortar palaki ma ka paia, inā ʻaʻole maikaʻi ke kūpaʻa o ka mortar i ka sag, e sag a paheʻe paha ka mortar, e hoʻopilikia nui ana i ka palahalaha o ka mortar, kahi e hoʻopilikia nui ai i ke kūkulu ʻana ma hope. No laila, pono i kahi mortar maikaʻi ke kūpaʻa thixotropy 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 luna, ua paheʻe pololei nā tile i lalo, ʻoiai ʻaʻole i paheʻe ka cellulose ether me ka viscosity o 150,000 a me 200,000. Ua kūkulu ʻia ke kihi i luna, ʻaʻohe paheʻe e hana ʻia.
Ikaika o ka palaki ʻana i ka mortar
Ma ka hoʻohana ʻana i 50,000, 100,000, 150,000, 200,000, a me 250,000 cellulose ethers e hoʻomākaukau i nā laʻana mortar plastering no ke kūkulu ʻana i ka mīkini, ua ʻike ʻia me ka hoʻonui ʻia ʻana o ka viscosity cellulose ether, ʻoi aku ka haʻahaʻa o ka waiwai ikaika o ka mortar plastering. ʻO kēia no ka mea, hana ka cellulose ether i kahi hopena viscosity kiʻekiʻe i loko o ka wai, a e hoʻokomo ʻia ka nui o nā pehu ea paʻa i ka wā o ke kaʻina hana kāwili ʻana o ka mortar. Ma hope o ka paʻakikī ʻana o ka sima, e hana kēia mau pehu ea i kahi nui o nā hakahaka, a laila e hōʻemi ana i ka waiwai ikaika o ka mortar. No laila, pono e hiki i ka mortar plastering kūpono no ke kūkulu ʻana i ka mīkini ke hoʻokō i ka waiwai ikaika e pono ai e ka hoʻolālā, a pono e koho ʻia kahi cellulose ether kūpono.
