ʻO nā pilikia maʻamau o ka putty pale wai no nā paia o loko

1. Nā pilikia maʻamau i ka pauka putty:

1.1 maloʻo wikiwiki.ʻO kēia ka mea pili i ka hoʻohui ʻana o ka calcium lehu a me ka paʻa ʻana o ka wai o ka fiber, a pili pū kekahi i ka maloʻo o ka pā.

1.2 ʻO ka ʻili a me ka ʻōwili ʻana.E pili ana kēia i ka nui o ka mālama ʻana i ka wai, maʻalahi ke hana i ka wā liʻiliʻi ka viscosity o cellulose a i ʻole ka liʻiliʻi o ka hoʻohui.

1.3 Wehe i ka pauda.Hoʻopili kēia i ka nui o ka calcium lehu i hoʻohui ʻia, a pili pū kekahi i ka nui a me ka maikaʻi o ka cellulose i hoʻohui ʻia.Hōʻike ʻia ia i ka pae paʻa wai o ka huahana.He haʻahaʻa ka paʻa wai a ʻaʻole lawa ka manawa hydration o ka calcium lehu.

1.4 Poha.Pili kēia i ka haʻahaʻa maloʻo a me ka palahalaha o ka pā, a pili pū kekahi i ke kūkulu ʻana.

1.5 Hōʻike ʻia kahi kiko pine.Pili kēia i ka cellulose, nona nā waiwai hana kiʻiʻoniʻoni maikaʻi ʻole.I ka manawa like, hoʻololi iki nā mea haumia i ka cellulose me ka calcium lehu.Inā koʻikoʻi ka hopena, e ʻike ʻia ka pauda putty ma ke ʻano o ke koena pīni.ʻAʻole hiki ke kau ʻia ma ka pā, a ʻaʻohe ikaika hoʻohui i ka manawa like.Eia kekahi, hiki mai kēia kūlana me nā huahana e like me nā hui carboxyl i hoʻohui ʻia i ka cellulose.

1.6 Hōʻike ʻia nā lua pele a me nā lua.ʻIke maopopo ʻia kēia e pili ana i ka ʻili o ka wai o ka hydroxypropyl methylcellulose aqueous solution.ʻAʻole ʻike ʻia ka ʻāʻī ʻana o ka pākaukau wai o ka hydroxyethyl aqueous solution.He mea maikaʻi ke hana i kahi lapaʻau hoʻopau.

1.7 Ma hope o ka maloʻo ʻana o ka putty, maʻalahi ka maʻi a huli melemele.Pili kēia i ka hoʻohui ʻana i ka nui o ka calcium hina.Inā hoʻohui nui ʻia ka nui o ka calcium hina, e piʻi ka paʻakikī o ka pauka putty ma hope o ka maloʻo ʻana.ʻO ka paʻakikī wale nō a ʻaʻole hiki ke maʻalahi ka maʻalahi, ʻoi aku ka paʻa ʻana i ka ikaika o waho.Ua pili pū me ka nui o ka calcium oxide i loko o ka calcium hina, i hoʻokomo mua ʻia.

2. No ke aha e lahilahi ai ka pauda putty ma hope o ka hoʻohui ʻana i ka wai?

Hoʻohana ʻia ʻo Cellulose ma ke ʻano he mānoanoa a me ka mea mālama wai i ka putty.Ma muli o ka thixotropy o cellulose ponoʻī, ʻo ka hoʻohui ʻana o ka cellulose i ka pauka putty e alakaʻi pū ai i ka thixotropy ma hope o ka hoʻohui ʻana i ka wai i ka putty.Hoʻokumu ʻia kēia thixotropy ma muli o ka luku ʻia ʻana o ka hui pū ʻana o nā mea i loko o ka pauka putty.Ke kū nei kēia hale i ka wā hoʻomaha a haki i lalo i ke kaumaha.ʻO ia hoʻi, emi ka viscosity ma lalo o ka hoʻoulu ʻana, a hoʻi ka viscosity ke kū mālie.

3. No ke aha i kaumaha ai ka putty i ka ʻōpala?

I kēia hihia, ʻoi aku ka kiʻekiʻe o ka viscosity o ka cellulose maʻamau.Hoʻohana kekahi mau mea hana i 200,000 cellulose e hana i ka putty.ʻO ka putty i hana ʻia ma kēia ʻano he viscosity kiʻekiʻe, no laila kaumaha ke kaumaha ke ʻoki.ʻO ka nui o ka putty i manaʻo ʻia no nā paia o loko he 3-5 kg, a ʻo ka viscosity he 80,000-100,000.

4. No ke aha i ʻokoʻa ai ka putty a me ka mortar me ka cellulose me ka viscosity like i ka hoʻoilo a me ke kauwela?

Ma muli o ka gelation thermal o ka huahana, e emi mālie ka viscosity o ka huahana me ka piʻi ʻana o ka mahana.Ke ʻoi aku ka mahana ma mua o ka mahana gel o ka huahana, e hoʻoheheʻe ʻia ka huahana mai ka wai a nalowale kona viscosity.ʻOi aku ka nui o ka mahana o ka lumi i ke kauwela ma luna o 30 degere, he ʻokoʻa loa ia mai ka mahana i ka hoʻoilo, no laila ua haʻahaʻa ka viscosity.Manaʻo ʻia e koho i kahi huahana me ka viscosity kiʻekiʻe i ke kauwela, a i ʻole e hoʻonui i ka nui o ka cellulose, a koho i kahi huahana me kahi mahana gel kiʻekiʻe.E ho'āʻo e koho i kahi huahana me ka mahana gel ma luna o 70 degere.E ho'āʻo e hoʻohana i ka methyl cellulose i ke kauwela, ʻo kona mahana gel ma kahi o 55 degere, inā ʻoi aku ka kiʻekiʻe o ka mahana, e hoʻopilikia nui ʻia kona viscosity.
