ʻO ka hanana o ka efflorescence i loko o ka mortar pili i ka hydroxypropyl methylcellulose?

ʻO ke ʻano o ka efflorescence ʻo ia: ʻo ka silicate ka mea maʻamau, a i ka wā e hālāwai ai me ka ea a i ʻole ka makū i loko o ka pā, e loaʻa ka silicate ion i kahi hopena hydrolysis, a hui pū ka hydroxide me nā ion metala e hana i kahi hydroxide me ka haʻahaʻa haʻahaʻa (ʻo ka waiwai kemika. Alkaline), i ka wā e piʻi ai ka mahana, e hoʻoheheʻe ʻia ka mahu wai, a hoʻoheheʻe ʻia ka hydroxide mai ka pā. Me ka hoʻoheheʻe ʻana o ka wai, ua hoʻoheheʻe ʻia ka hydroxide ma luna o ka ʻili o ka sima sima. I ka hala ʻana o ka manawa, hoʻokiʻekiʻe ʻia ka pena hoʻonaninani kumu a i ʻole ka pena a me nā mea ʻē aʻe a pili ʻole i ka paia, a hiki mai ke keʻokeʻo, ka ʻili, a me ka ʻili. Kapa ʻia kēia hana ʻo "pan-alkali". No laila, ʻaʻole ia ka ubiquinol i hana ʻia e ka hydroxypropyl methylcellulose.

Ua ʻōlelo ka mea kūʻai aku i kahi hanana: ʻo ka grout sprayed āna i hana ai e loaʻa iā ia ka pan-alkali ma ka pā pōhaku, akā ʻaʻole e ʻike ʻia ma ka pā pōhaku i puhi ʻia, e hōʻike ana i ka silicic acid i loko o ka sima i hoʻohana ʻia ma ka pā paʻakai Nui loa ka paʻakai (ikaika. paʻakai alkaline). Efflorescence ma muli o ka evaporation o ka wai i hoʻohana ʻia i ka spray grouting. Eia naʻe, ʻaʻohe silicate ma ka pā pōhaku i puhi ʻia a ʻaʻohe efflorescence e hiki mai. No laila, ʻaʻohe mea e pili ana i ka efflorescence me ka pulupulu.

Hoʻoholo

1. Ho'emi 'ia ka mea silicate o ka sima sima kumu.

2. E hoʻohana i ka anti-alkali back coating agent, e komo ka hoʻonā i loko o ka pōhaku e ālai i ka capillary, i hiki ʻole i ka wai, Ca(OH)2, ka paʻakai a me nā mea ʻē aʻe ke komo, a ʻoki i ke ala o ka hanana pan-alkaline.

3. No ka pale ʻana i ka komo ʻana o ka wai, mai kāpīpī i ka wai nui ma mua o ke kūkulu ʻana.

Lapaʻau ʻana i ka hanana pan-alkaline

Hiki ke hoʻohana ʻia ka mea hoʻomaʻemaʻe pōhaku efflorescence ma ka mākeke. ʻO kēia mea hoʻomaʻemaʻe he wai translucent kala ʻole i hana ʻia me nā surfactants non-ionic a me nā solvents. He hopena koʻikoʻi ma ka hoʻomaʻemaʻe ʻana i kekahi mau ʻili pōhaku maoli. Akā ma mua o ka hoʻohana ʻana, e hoʻomaopopo pono e hana i kahi poloka hoʻāʻo liʻiliʻi e hoʻāʻo ai i ka hopena a hoʻoholo inā e hoʻohana.
