1. ʻEpekema Mea a me Mechanism Hana
1.1 ʻO ke ʻano a me ka hoʻokaʻawale ʻana o nā mea hoʻohui māmā
(Nā Pākuʻi Paʻa Māmā)
ʻO nā mea hoʻohui paʻa māmā he mea kemika kūikawā a i ʻole nā mea hoʻohui kino i hoʻolālā ʻia e hoʻemi i ka nui o nā ʻōnaehana cementitious i ka wā e mālama ai a hoʻomaikaʻi paha i ka hana a me ka pono..
ʻAʻole like me nā hui kuʻuna, ʻO kēia mau mea hoʻohui e hōʻike nei i ka porosity i hoʻomalu ʻia a i ʻole e hoʻokomo i nā ʻāpana haʻahaʻa haʻahaʻa i loko o ka matrix siki, ka hopena i nā paona mea maʻamau mai 800 i 1800 kg/m ELUA, hoʻohālikelike ʻia me 2300– 2500 kg/m ³ no ke kaila mau.
Hoʻokaʻawale ʻia lākou i ʻelua mau ʻano: nā mea hoʻohuhū kemika a me nā hui māmā māmā.
Hana maikaʻi nā ʻelele hoʻohuehu kemika, nā āwaha ea kūpaʻa ma o ka hoʻokuʻu kinoea in-situ– ʻO ka maʻamau ma o ka pauka alumini i loko o ka ʻekeʻeke aerated autoclaved (AAC) a i ʻole hydrogen peroxide me nā mea hoʻoheheʻe– ʻoiai nā mea i hoʻokomo mua ʻia me ka polystyrene ākea (EPS) palaoa, perlite, vermiculite, a me nā microspheres hollow ceramic a polymer.
Hoʻopili pū nā ʻano ʻokoʻa kiʻekiʻe i ke silica permeable nanostructured, aerogels, a me nā hōʻiliʻili māmā i hana hou ʻia mai nā huahana ʻoihana e like me ke aniani ākea a i ʻole ka slag.
ʻO ke koho o ka admixture e pili ana i ka insulation thermal e pono ai, hoʻoikaika kino, pale ahi, a me ka hiki ke hana, hoʻolilo iā lākou i mea maʻalahi i nā pono hale like ʻole.
1.2 ʻO ka Pore Structure and Density-Property Relations
ʻO ka maikaʻi o ka māmā māmā ke hoʻomaluʻia e ka morphology, mahele nui, a me ka pilina o nā pores i hoʻokomo ʻia e ka admixture.
Loaʻa nā ʻōnaehana kūpono i ka pālahalaha like, nā pores i pani ʻia me nā nui ma waena 50 a 500 micrometers, e hōʻemi ana i ka hoʻoheheʻe ʻana i ka wai a me ka conductivity thermal i ka wā e hoʻohana pono ai i ka hana insulation.
Wehe a i ʻole nā pores pili, oiai e emi ana ka nui, hiki ke hoʻololi i ka ikaika a me ka lōʻihi ma ke kōkua ʻana i ka loaʻa ʻana o ka pulu a me nā pōʻino maloʻo.
Hoʻohui maikaʻi ʻia, ʻōhū kaʻawale– e like me ka hoʻokumu ʻana i ka protein a i ʻole nā mea hoʻoheheʻe i hana ʻia i loko o ka pahu pahu– hoʻonui i ka paʻa mechanical a me ka hana wela.
Ua hoʻokumu maikaʻi ʻia ka pilina inverse ma waena o ka density a me ka paʻakikī compressive; akā naʻe, ʻO nā mea hoʻohui hui hou e hoʻēmi i kēia kālepa-off ma o ka matrix densification, hoʻoikaika fiber, a me ka hoʻomaʻamaʻa maikaʻi ʻana.
( Nā Pākuʻi Paʻa Māmā)
ʻo kahi laʻana, hoʻokomo i ka mahu silica a i ʻole lehu lele me nā ʻelele huʻihue e hoʻokani maikaʻi i ka pore framework a hoʻomaikaʻi i ka paʻi koneki., hiki i ka ikaika kiʻekiʻe māmā māmā (a hiki i 40 MPa) no nā hana hoʻolālā.
2. ʻO ke ʻano hui hui kī a me kā lākou mau hana ʻenekinia
2.1 ʻO nā mea kūʻai hoʻoheheʻe a me nā mea hoʻonā ea
ʻO nā ʻelele i hoʻokumu ʻia i ka protein a me ka synthetic frothing ʻo ia ke kumu o ka hana ʻana o ka foam concrete, ka hana ʻana i nā ʻōhū ea paʻa i hoʻohui ʻia me ka mīkini i loko o ka slurry.
ʻO nā pūmua ola kino, loaʻa mai nā kumu holoholona a mea ʻai paha, hāʻawi i ka palekana o ka pahu kiʻekiʻe a kūpono no nā noi haʻahaʻa haʻahaʻa (
ʻO Cabr-Concrete ka mea hoʻolako i ka Concrete Admixture me ka ʻoi aku 12 mau makahiki o ka ʻike i ka mālama ʻana i ka ikehu kūkulu nano a me ka hoʻomohala ʻana i ka nanotechnology. ʻAe ia i ka uku ma o Kāleka Kāleka, T/T, West Union a me Paypal. E hoʻouna ʻo TRUNNANO i nā waiwai i nā mea kūʻai aku ma waho ma o FedEx, DHL, ma ka lewa, a ma ke kai paha. Inā ʻoe e ʻimi nei i ke kiʻekiʻe kiʻekiʻe Concrete Admixture, eʻoluʻolu e leka uila iā mākou a hoʻouna i kahi nīnau.
Nā huaʻōlelo: Nā Pākuʻi Paʻa Māmā, nā mea hoʻohui paʻa, mea hoʻohui ʻia
ʻO nā ʻatikala a me nā kiʻi a pau mai ka Pūnaewele. Inā loaʻa kekahi pilikia kope, e ʻoluʻolu e kelepona mai iā mākou i ka manawa e holoi ai.
