Ka hopena o ka Cellulose Ether ma ka Putty Powder Application

He aha ke kumu e maloʻo koke ai ka pauda putty?

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.

Pehea 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.

Loaʻa iā ia nā kiko kiko i kekahi manawa?

Pili kēia i ka cellulose, nona nā waiwai hana kiʻiʻoniʻoni maikaʻi ʻole, a 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 e like me ke koena pī. 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.

Nā lua pele a me nā pū?

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 ka hoʻopau ʻana.

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 i 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 hoʻihoʻi ka viscosity i 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 ʻia. 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 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 nā huahana me ka mahana gel kiʻekiʻe i ka wā e noi ai i nā huahana i ke kauwela. ʻO ka mahana gel o ka huahana ma luna o 75 degere. Wall putty national standard (JG/T298-2009) nā koi maʻamau, paʻa ka maikaʻi o ka huahana, maikaʻi ka hana kaiapuni zero voc. ʻO ka maʻamau, ʻo ka mahana gel o ka methyl cellulose ma kahi o 55 degere i ke kauwela. Inā piʻi iki ka mahana, e hoʻopilikia nui ʻia kona viscosity.
