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

1. Nā pilikia maʻamau i ka pauka putty

maloʻo koke

ʻO ke kumu nui o kēia, ʻo ia ka nui o ka pauka kalipuna lehu i hoʻohui ʻia (inā nui loa, hiki ke hoʻemi kūpono ʻia ka nui o ka pauka kalipuna lehu i hoʻohana ʻia i loko o ke ʻano putty) a me ka nui o ka paʻa ʻana o ka wai o ka hydroxypropyl methylcellulose (HPMC), a pili pū kekahi i ka maloʻo o ka paia.

Ke ʻili ʻana a me ka ʻōwili ʻana

Pili kēia i ka nui o ka paʻa ʻana o ka wai, kahi mea maʻalahi ke hana ke haʻahaʻa ka viscosity o ka hydroxypropyl methylcellulose (HPMC) a i ʻole he liʻiliʻi ka nui i hoʻohui ʻia.

Ka wehe ʻana i ka pauka o ka pauka putty paia o loko

Pili kēia i ka nui o ka pauka kalipuna lehu (ʻo ka nui o ka pauka kalipuna lehu i loko o ke ʻano putty he liʻiliʻi loa ia a i ʻole ka maʻemaʻe o ka pauka kalipuna lehu, a pono e hoʻonui pono ʻia ka nui o ka pauka kalipuna lehu i loko o ke ʻano putty), a pili pū kekahi i ka nui o ka hydroxypropyl methyl. Pili ka nui o ke kumu cellulose (HPMC) i ke ʻano, kahi i hōʻike ʻia i ka helu paʻa wai o ka huahana. Haʻahaʻa ka helu paʻa wai, a ʻaʻole lawa ka manawa no ka pauka kalipuna lehu (ʻaʻole i hoʻololi piha ʻia ka calcium oxide i loko o ka pauka kalipuna lehu i calcium hydroxide). ,i hana ʻia.

e pehu ana

Pili kēia i ka makū maloʻo a me ka palahalaha o ka paia, a pili pū kekahi i ke kūkulu ʻana.

kiko pine

Pili kēia i ka cellulose, nona nā waiwai hana ʻili maikaʻi ʻole. I ka manawa like, pane iki nā mea haumia i loko o ka hydroxypropyl methylcellulose (HPMC) me ka lehu calcium. Inā koʻikoʻi ka hopena, e like ka pauka putty me ke koena bean curd. ʻAʻole hiki ke kau ʻia ma ka paia, a ʻaʻohe ona ikaika hoʻopili i ka manawa like. Eia kekahi, ʻike ʻia nā huahana e like me ka hydroxypropyl methylcellulose (HPMC) i hui pū ʻia me ka hui carboxymethyl i kēia kūlana.

ʻIke ʻia nā lua pele a me nā lua pinholes

He mea maopopo kēia e pili ana i ka ʻumekaumaha o ka ʻilikai o ka wai hydroxypropyl methylcellulose (HPMC). ʻAʻole maopopo ka ʻumekaumaha o ka papa wai o ka wai hydroxyethyl. He mea maikaʻi ke hana i kahi hana hoʻopau.

Ma hope o ka maloʻo ʻana o ka putty, he maʻalahi ke haki a huli i ka melemele

Pili kēia i ka hoʻohui ʻana o ka nui o ka pauka lehu-calcium. Inā hoʻohui nui ʻia ka nui o ka pauka lehu-calcium, e piʻi aʻe ka paʻakikī o ka pauka putty ma hope o ka maloʻo ʻana. Inā ʻaʻohe palupalu o ka pauka putty, e nahā maʻalahi ia, ʻoiai ke kau ʻia i ka ikaika o waho. Pili pū kekahi i ka nui o ka calcium oxide i loko o ka pauka lehu calcium.

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

Hoʻohana ʻia ʻo Hydroxypropyl methylcellulose (HPMC) ma ke ʻano he mea hoʻomānoanoa a me ka mea mālama wai i loko o ka ʻaila momona. Ma muli o ka thixotropy o ka hydroxypropyl methylcellulose (HPMC), ʻo ka hydroxypropyl methylcellulose i loko o ka pauka putty. ʻO ka hoʻohui ʻana o HPMC i hana pū i ka thixotropy ma hope o ka hoʻohui ʻana i ka wai i ka putty. Hoʻokumu ʻia kēia thixotropy e ka luku ʻia ʻana o ke ʻano hui ʻole o nā ʻāpana i loko o ka pauka putty. Kū aʻe kēia ʻano i ka wā hoʻomaha a haki i lalo o ke kaumaha. ʻO ia hoʻi, emi ka viscosity i lalo o ka hoʻoulu ʻana, a hoʻihoʻi ka viscosity i ka wā e kū mālie ai.

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

I kēia hihia, ʻoi aku ka kiʻekiʻe o ka viscosity o ka hydroxypropyl methylcellulose (HPMC) i hoʻohana nui ʻia, a hoʻohana kekahi mau mea hana i 200,000 yuan e hana i ka putty. Loaʻa i ka putty i hana ʻia ma kēia ʻano kahi viscosity kiʻekiʻe, no laila e piholo ia i ka wā e ʻoki ʻia ai ka nui. he manaʻo o. ʻO ka nui i ʻōlelo ʻia o ka putty no nā paia o loko he 3-5 kg, a ʻo ka viscosity he 80,000-100,000.

4. No ke aha ʻoe e manaʻo ai he ʻokoʻa ka mānoanoa o ka hydroxypropyl methylcellulose (HPMC) me ka mānoanoa 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 mahana o ka lumi i ke kauwela ma mua 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 hoʻopili 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 ka mahana gel kiʻekiʻe.
