maloʻo wikiwiki
ʻO ka mea nui kēia ma muli o ka hoʻohui nui ʻana o ka pauka calcium lehu (hiki ke hoʻemi ʻia ka nui o ka pauka calcium lehu i hoʻohana ʻia i ke ʻano putty) pili i ka pae paʻa wai o ka hydroxypropyl methylcellulose, a pili pū kekahi i ka maloʻo o ka pā. .
ʻO kaʻili a me ka'ōwili
Pili kēia i ka mea kiʻekiʻe o ka lehu calcium a i ʻole ka haʻahaʻa o ka mālama ʻana i ka wai o ka hydroxypropyl methylcellulose, a hiki nō hoʻi ke hana i ka wā e haʻahaʻa ai ka viscosity o cellulose a i ʻole ka liʻiliʻi o ka hoʻohui.
Wehe i ka pauda o ka pauda putty pā o loko
Pili kēia i ka nui o ka pauda calcium lehu i hoʻohui ʻia (ʻo ka nui o ka pauda calcium lehu i loko o ke kumu putty he liʻiliʻi loa a i ʻole he haʻahaʻa loa ka maʻemaʻe o ka pauda calcium lehu, a ʻo ka nui o ka pauda calcium lehu i loko o ke ʻano pauda putty pono. e hoʻonui pono ʻia), a pili pū i ka hoʻohui ʻana i ka cellulose Aia kahi pilina ma waena o ka nui a me ka maikaʻi, i hōʻike ʻia i ka pae paʻa wai o ka huahana.He haʻahaʻa ka nui o ka mālama ʻana o ka wai, a ʻaʻole lawa ka manawa pane o ka pauka calcium lehu (ʻaʻole i hoʻololi piha ʻia ka calcium oxide i ka pauka calcium lehu i ka calcium hydroxide), ʻo ia ke kumu.
ʻōhū
Pili kēia i ka haʻahaʻa maloʻo a me ka palahalaha o ka pā, a pili pū kekahi i ke kūkulu ʻana.
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 luna o ka pā, a ʻaʻohe ikaika hoʻohui i ka manawa like.Eia kekahi, hiki mai kēia kūlana me nā huahana e like me carboxymethyl i hui pū ʻia me cellulose.
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.Ua pili pū me ka hoʻohui nui o ka hydroxypropyl methylcellulose.
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 pauka lehu-calcium.Inā hoʻohui nui ʻia ka nui o ka pauka lehu-calcium, e piʻi ka paʻakikī o ka pauka putty ma hope o ka maloʻo ʻana.Inā ʻaʻohe maʻalahi o ka pauka putty, e maʻalahi ia, ʻoi aku ka maikaʻi ke kau ʻia i ka ikaika o waho.Ua pili pū i ka nui o ka calcium oxide i loko o ka lepo calcium lehu.
No ke aha e ʻoi aku ka lahilahi o ka pauka 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 ma ka putty.Ma muli o ka thixotropy o ka cellulose ponoʻī, ʻo ka hoʻohui ʻana o ka cellulose i ka pauka putty e alakaʻi 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 wāwahi i lalo o ke kaumaha.ʻO ia hoʻi, emi ka viscosity ma lalo o ka hoʻoulu ʻana, a hoʻi ka viscosity ke kū mālie.
He aha ke kumu 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.
No ke aha i ʻokoʻa ai ka viscosity o ka cellulose i ka hoʻohana ʻana i ka cellulose 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 putty a me ka mortar 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 ka wā e noi ai i ka huahana i ke kauwela, a i ʻole e hoʻonui i ka nui o ka cellulose, a koho i kahi huahana me kahi kiʻekiʻe o ka gel wela.
