Ka hana o ka cellulose ether i loko o ka mortar

ʻEtera celluloseka paʻa ʻana o ka wai

ʻO ka paʻa ʻana o ka wai o ka mortar e pili ana i ka hiki o ka mortar ke paʻa a hoʻopaʻa i ka wai. ʻO ke kiʻekiʻe o ka viscosity o ka cellulose ether, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai. No ka mea, aia i loko o ke ʻano o ka cellulose ka pilina hydroxyl a me ka ether, ka hui hydroxyl a me ka ether o nā ʻātoma oxygen a me nā mole wai e hana i ka pilina hydrogen, i hiki ai i ka wai ke hoʻokuʻu i ka wai i loko o ka wai e hoʻopaʻa ai, e wili ana i ka wai, i mea e pāʻani ai i kahi hana o ka paʻa ʻana o ka wai.

Ka hoʻoheheʻe ʻia ʻana o ka cellulose ether

1. He maʻalahi ka hoʻopuehu ʻana o ka cellulose ether coarser i ka wai me ka ʻole o ka agglomerating, akā lohi loa ka wikiwiki o ka hoʻoheheʻe ʻana. Hoʻoheheʻe ʻia ka cellulose ether ma lalo o 60 mesh i loko o ka wai no kahi o 60 mau minuke.

2. He maʻalahi ka hoʻopuehu ʻana i nā ʻāpana liʻiliʻi o ka cellulose ether i loko o ka wai a ʻaʻole e hoʻopili ʻia, a he kūpono ka nui o ka hoʻoheheʻe ʻana. Ua hoʻoheheʻe ʻia ka cellulose ether ma luna o 80 mesh i loko o ka wai no kahi o 3 mau minuke.

3. Hoʻopuehu koke ka cellulose ether maikaʻi loa i ka wai, hoʻoheheʻe koke a hana i kahi mānoanoa wikiwiki. Hoʻoheheʻe ʻia ka cellulose ether ma luna o 120 mesh i ka wai no kahi o 10-30 kekona.

ʻO ka ʻoi aku ka maikaʻi o nā ʻāpana cellulose ether, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai, nā ʻāpana coarse o ka cellulose ether a me ka wai e pili ana i ka wai e hoʻoheheʻe koke ʻia a hana ʻia kahi hanana gel. Hoʻopili ka glue i ka mea e pale ai i nā mole wai mai ka hoʻomau ʻana i ke komo ʻana. I kekahi manawa, ʻoiai inā e hoʻoulu ʻia no ka manawa lōʻihi, ʻaʻole hiki ke hoʻopuehu like ʻia a hoʻoheheʻe ʻia ka hopena, e hana ana i kahi hopena flocculent muddy a i ʻole agglomerate. Hoʻopuehu koke nā ʻāpana maikaʻi a hoʻoheheʻe ʻia ma hope o ka hoʻopili ʻana me ka wai e hana i kahi viscosity like.

Ka waiwai PH o ka cellulose ether (coagulation lohi a i ʻole ka ikaika mua)

ʻO ke kumukūʻai PH o nā mea hana cellulose ether ma ka home a me waho e kāohi ʻia ma kahi o 7, he waikawa ia. No ka mea, he nui nō ke ʻano o ke apo glucose dehydrated i loko o ke ʻano molekala o ka cellulose ether, ʻo ke apo glucose dehydrated ka hui nui e hoʻopaneʻe ai i ka sima. Hiki i ke apo glucose dehydrated ke hana i nā ion calcium i loko o ka hopena hydration sima e hana i nā hui molekala calcium kō, e hoʻemi i ka nui o ka ion calcium i ka wā hoʻokomo hydration sima, e pale i ka hoʻokumu ʻana a me ka ua ʻana o ka calcium hydroxide a me nā kristal paʻakai calcium, a laila e hoʻopaneʻe ana i ke kaʻina hana o ka hydration sima. Inā lilo ka waiwai PH i mokuʻāina alkaline, e ʻike ʻia ka mortar i ka mokuʻāina ikaika mua. I kēia manawa, ʻo ka hapa nui o nā hale hana e hoʻoponopono i ka waiwai PH me ka hoʻohana ʻana i ka sodium carbonate, ʻo ka sodium carbonate kahi ʻano o ka mea hoʻolalelale, hiki i ka sodium carbonate ke hoʻomaikaʻi i ka hana o ka ʻili o nā ʻāpana sima, e hoʻoulu ai i ka hoʻohuihui ma waena o nā ʻāpana e hoʻonui, e hoʻomaikaʻi hou i ka viscosity o ka slurry, mortar a me ka sodium carbonate a me ka hui ion calcium wikiwiki, e hoʻoulu ai i ka hoʻokumu ʻana o ka ettringite, condensation sima wikiwiki. No laila, pono e hoʻoponopono ʻia ka waiwai PH e like me nā mea kūʻai aku like ʻole i ke kaʻina hana maoli.

Hoʻokomo kinoea cellulose ether

ʻO ke komo ʻana o ka cellulose ether i ka ea ma muli o ka mea he surfactant nō hoʻi ka cellulose ether, ʻo ka hana interface o ka cellulose ether e hana nui ʻia ma ka interface gas-wai-paʻa, ʻo ka mea mua ka hoʻolauna ʻana o nā pehu, a ukali ʻia e ka hoʻopuehu ʻana a me ka pulu ʻana. Loaʻa i ka cellulose ether ka hui alkyl, e hoʻemi nui ana i ka ʻili o ka ʻili a me ka ikehu interfacial o ka wai, a maʻalahi ka hoʻoheheʻe wai i ke kaʻina hana o ka hoʻoulu ʻana e hana i nā pehu liʻiliʻi he nui.

Ka hoʻoheheʻe ʻana o ka cellulose ether

Ma muli o kona kaulahao molekala o ka methoxy a me ka hui hydroxypropyl i loko o ka slurry me nā ion calcium a me nā ion alumini i hoʻoheheʻe ʻia i loko o ka gel viscous a hoʻopiha i ka hakahaka sima mortar, hoʻomaikaʻi i ka nui o ka mortar, a pāʻani i kahi hana o ka hoʻopiha palupalu a me ka hoʻoikaika. Eia naʻe, i ka wā e kaomi ʻia ai ka matrix composite, ʻaʻole hiki i ka polymer ke pāʻani i kahi kākoʻo paʻa, no laila e emi ana ka ikaika a me ka lakio compression o ka mortar.

Hoʻokumu ʻia ʻana o ke kiʻiʻoniʻoniʻEtera cellulose

Hoʻokumu ʻia kahi ʻili latex lahilahi ma waena o ka cellulose ether a me nā ʻāpana sima ma hope o ka hydration. Loaʻa i ka ʻili ka hopena sila a hoʻomaikaʻi i ka hanana maloʻo o ka ʻili o ka mortar. Ma muli o ka paʻa maikaʻi ʻana o ka wai o ka cellulose ether, mālama i nā molekala wai lawa i loko o ka mortar, no laila e hōʻoiaʻiʻo ana i ka ikaika o ka hydration a me ka paʻakikī o ka sima a me ka hoʻomohala piha ʻana, hoʻomaikaʻi i ka ikaika hoʻopaʻa o ka mortar, i ka manawa like e hoʻomaikaʻi ai i ka hoʻopili ʻana o ka mortar sima, he plasticity maikaʻi a me ka paʻakikī o ka mortar, e hōʻemi ana i ka deformation contraction mortar.
