E pili ana i ka hydroxypropyl methylcellulose i ka hoʻohana ʻana i ka pauka putty

1. Nā pilikia maʻamau i ka pauka putty

maloo wikiwiki

ʻO ka nui o kēia e pili ana i ka nui o ka pauka calcium lehu i hoʻohui ʻia (nui loa, hiki ke hoʻemi ʻia ka nui o ka pauka calcium lehu i hoʻohana ʻia i ke ʻano putty) a me ka pae paʻa wai o ka hydroxypropyl methylcellulose (HPMC), a pili pū me ia. pili ka maloʻo o ka pā.

ʻO kaʻiliʻana a me ka'ōwili

Pili kēia i ka nui o ka mālama ʻana i ka wai, hiki ke maʻalahi i ka wā i haʻahaʻa ai ka viscosity o ka hydroxypropyl methylcellulose (HPMC) a i ʻole ka liʻiliʻi o ka nui i hoʻohui ʻia.

Ka pauda ʻana o ka pauda putty pā o loko

Pili kēia i ka nui o ka pauda calcium lehu (ʻo ka nui o ka pauda calcium lehu i loko o ke ʻano putty he liʻiliʻi loa a i ʻole ka haʻahaʻa loa o ka maʻemaʻe o ka pauka calcium lehu, a ʻo ka nui o ka pauda calcium lehu i loko o ke ʻano pauda putty e pono. hoʻonui kūpono), a pili pū i ka nui o ka hydroxypropyl methyl ʻO ka nui o ka cellulose base (HPMC) e pili ana i ka maikaʻi, i hōʻike ʻia i ka pae paʻa wai o ka huahana. He haʻahaʻa ka nui o ka paʻa ʻana o ka wai, a ʻaʻole lawa ka manawa no ka pauka calcium lehu (ʻaʻole i hoʻololi piha ʻia ka pauka calcium oxide i ka pauka calcium lehu i ka calcium hydroxide). , 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 hydroxypropyl methylcellulose (HPMC) me ka calcium lehu. Inā ko'iko'i ka hopena, aia ka pauda putty i ke koena o ka pī. ʻAʻole hiki ke kau ʻia ma luna o ka pā, a ʻaʻohe ikaika hoʻohui i ka manawa like. Eia kekahi, ʻike pū ʻia nā huahana e like me ka hydroxypropyl methylcellulose (HPMC) i hui pū ʻia me ka hui carboxymethyl i kēia kūlana.

Hōʻike ʻia nā lua pele a me nā lua

ʻIke maopopo ʻia kēia e pili ana i ka ʻili o ka wai o ka wai wai hydroxypropyl methylcellulose (HPMC). ʻAʻole ʻike ʻia ka ʻāʻī ʻana o ka pākaukau wai o ka hydroxyethyl aqueous solution. He mea maikaʻi ke hana i kahi lapaʻau hoʻopau.

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.

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

Hoʻohana ʻia ʻo Hydroxypropyl methylcellulose (HPMC) ma ke ʻano he mānoanoa a me ka mea mālama wai i ka momona. Ma muli o ka thixotropy o ka hydroxypropyl methylcellulose (HPMC), ka hydroxypropyl methylcellulose i loko o ka pauka putty ʻO ka hoʻohui ʻana o HPMC i hana 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 hoʻihoʻi ka viscosity i ke kū mālie.

3. He aha ke kumu i kaumaha ai ka putty i ke kaʻina ʻōpala?

I kēia hihia, ʻoi aku ka kiʻekiʻe o ka viscosity o ka hydroxypropyl methylcellulose (HPMC) i hoʻohana maʻamau, a hoʻohana kekahi mau mea hana i 200,000 yuan e hana i ka putty. ʻO ka putty i hana ʻia ma kēia ʻano he viscosity kiʻekiʻe, no laila e pohō i ka wā e ʻoki ʻia ai. he manao o. 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 ʻoe i manaʻo ai he ʻokoʻa ka viscosity o ka hydroxypropyl methylcellulose (HPMC) 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 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 emi ka viscosity. Manaʻo ʻia e koho i kahi huahana me ka viscosity kiʻekiʻe i ka wā e hoʻohana ai i ka huahana i ke kauwela, a i ʻole e hoʻonui i ka nui o ka hydroxypropyl methylcellulose (HPMC), a e koho i kahi huahana me kahi mahana gel kiʻekiʻe.
