E hoʻohui ana i ka hydroxypropyl methylcellulose i ka ʻūhā

He aha ka Foam Concrete?

ʻO Foamed concrete kahi ʻano hou o ka ikehu-ola a me ke kaiapuni hale mea i loaʻa i ka nui o nā pores i hoʻopaʻa like ʻia, he māmā, kūpaʻa wela, hoʻomaʻamaʻa a me ke kani, a he kūpono loa ia no nā ʻōnaehana pale o waho. o na hale. Hiki ke ʻike ʻia mai ʻaneʻi, i mea e hoʻolohi ai i nā ʻano ʻano like ʻole o ka ʻūhā pahu, pono nā mea hoʻohui i kēia mau waiwai. No laila, ma ke ʻano he mea waiwai nui loa o ka pahu pahu, ʻo ka hydroxypropyl methylcellulose kahi mea hale me ka paʻa wai kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe a me ka adhesion ikaika.

No ke aha i hoʻohui ʻia ai ka hydroxypropyl methylcellulose i loko o ka pahu pahu:

E like me ka mea e pili ana i ka ʻenehana hana o kēia manawa, nui nā pores i pani ʻia i loko o ka pahu pahu ʻaʻole i kū maoli, akā ua hana ʻia e ka waiho ʻana i nā mea maka e like me ka hydroxypropyl methylcellulose i loko o nā mea hoʻohui a hui pū ʻia no ka manawa lōʻihi. Hoʻopau maikaʻi kēia ʻano pores i pani ʻia i ke ʻano o ka ʻōpala nui o nā mea hoʻopihapiha a mālama i nā kumukūʻai i kahi nui. E nīnau kekahi poʻe inā ʻaʻohe hopena like me ka hoʻohui ʻole ʻana i ka hydroxypropyl methylcellulose? Hiki iaʻu ke haʻi aku iā ʻoe me ka maopopo, ʻae. Ma muli o nā waiwai kūikawā o ka hydroxypropyl methylcellulose, hiki iā ia ke hoʻohui maikaʻi i nā mea maka like ʻole, i hiki ke hana ʻia kahi mana cohesive kūikawā ma waena o lākou, a hiki ke hoʻonui ʻia kona kūpaʻa tensile a extrusion.
