He "mea hoʻohana waiwai nui" ko kākou ʻāina i ke aniani. Me ka wikiwiki o ka hoʻomohala waiwai, ke piʻi nei ka hoʻohana ʻana i ke aniani i kēlā me kēia lā, a ua lilo mālie ka hoʻolei ʻana i nā aniani ʻōpala i mea paʻakikī. ʻO ka ʻāpana nui o ke aniani he silica hana, no laila ma hope o ka wili ʻia ʻana i pauka, hiki iā ia ke loaʻa ka hana pozzolanic a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui e hoʻomākaukau ai i ka sima. ʻAʻole hiki i kēia ke hoʻoponopono wale i ka pilikia o ka hoʻolei ʻana i nā aniani ʻōpala, akā e paipai pū i ka hoʻomohala ʻana i nā mea kūkulu hale ʻōmaʻomaʻo a aloha i ke kaiapuni.Mīkini HCMhe mea hana wili wili. ʻO ka wili wili a mākou e hana ai he mau lako i hoʻohana ʻia e wili i ka pauka aniani ʻōpala. I kēia lā e hoʻolauna aku wau iā ʻoe i ke kuleana o ka pauka aniani ma ka sima.

Ma ka nānā ʻana i ka hoʻāʻo ikaika compressive o ka sima i hui pū ʻia me ka pauka aniani a me nā hopena hoʻokolokolo microscopic o ka paʻi sima, hiki ke hoʻoholo ʻia ʻoiai hiki i ka CaO o ka pauka aniani ke pane me ka wai, he nāwaliwali loa ia. No laila, hiki ke manaʻo ʻia ʻaʻohe paʻakikī hydraulic o ka pauka aniani. Ke 10% ka nui o ka hui ʻana o ka pauka aniani, no ka laʻana, ʻo ka silica hana, alumina a me ka calcium hydroxide i loko o ka pauka aniani e pane e hana i ka calcium silicate hydrated alkalinity haʻahaʻa. Hiki i ka silica hana ke pane me ka calcium silicate hydrated alkalinity kiʻekiʻe. Hoʻopili ka calcium silicate hydrate e hana i ka calcium silicate hydrated alkalinity haʻahaʻa. ʻOiai e hoʻemi ana i ka ʻike calcium hydroxide, hana ʻia kahi ʻāpana o ka calcium silicate hydrated, kahi e hoʻomaikaʻi ai i ka density a me ka impermeability o ka slurry paʻakikī; Hoʻopili ia me ka huahana hydration sima calcium hydroxide (Ca(OH)2) e hana i ka wai. Hoʻemi ka hydrated calcium silicate i ka ʻike o Ca(OH)2 i loko o ka sima, hoʻonui i ka ʻike o ka hydrated calcium silicate, a hoʻomaikaʻi i ka ikaika o ka sima. Ke hiki ka ʻike o ka pauka aniani i 20%, no ka mea, emi ka ʻike o ka sima, emi pū nā hydrates i hana ʻia e ka hydration sima, akā hoʻopili ka pauka aniani me nā hydrates sima e hana i ka calcium silicate hydrated hapa. Ke hiki ka nui o ka pauka aniani i 20%, ua like nō ka ikaika me ka sima benchmark. Ke hoʻomau ka nui o ka pauka aniani i ka piʻi ʻana a emi mālie ka ʻike o ka sima, emi ka nui o nā huahana hydration, a hoʻopili ka pauka aniani me nā hydrates sima ʻAʻole lawa ka hydrate i hoʻonui ʻia e uku no ka emi ʻana o nā huahana hydration i hoʻokumu ʻia e ka emi ʻana o ka ʻike o ka sima. No laila, ke emi nei ka ikaika. Ua ʻike ʻia hoʻi i ka wā e nui loa ai ka nui o ka pauka aniani, e ʻike ʻia nā māwae.

ʻO kēia no ka mea ʻoiai ua emi ka nui o ka sima, ua emi pū ka noi no ka silica hana e komo ana i ka hopena hydration. Hoʻopili ka silica hana i koe me nā mea alkaline i loko o ka pauka aniani, e hoʻoulu ai i ka hoʻonui ʻana o loko o ka sima. E haki pū ka paʻi sima paʻakikī a hana i nā māwae nui aʻe, a e emi pū ka ikaika o ka sima.

Ka hopena o ka pauka aniani ma ka sima:

(1) ʻOi aku ka ikaika compressive 28 lā o ka sima i hoʻomākaukau ʻia me ka pauka aniani moakaka ʻole a me ka pauka aniani ʻōmaʻomaʻo i hui pū ʻia me 10% a me 15% o ka sima ma kahi o ka sima ma mua o ka sima benchmark; i ka wā he 20% ka dosage, ua like ka ikaika me ka sima benchmark. Hoʻohālikelike ʻia me ka sima; i ka wā he 30% a ʻoi aku ka dosage, emi nui ka ikaika compressive o ka sima.

(2) Ke hoʻohui ʻole ʻia ka pauka aniani, hoʻopili maikaʻi ʻia ka calcium hydroxide a ʻoi aku ka nui. I ka piʻi ʻana o ka nui o ka pauka aniani, e emi mālie ana ka nui o ka calcium hydroxide a e ʻoi aku ka ʻino o ka crystallization.

(3) ʻAʻole nui ka hopena o ka hoʻohui ʻana i ka pauka aniani o nā kala like ʻole i ka ikaika o ka sima.

(4) Hoʻohana ʻia ka pauka aniani e hoʻomākaukau i ka sima a he hopena maikaʻi loa ia no ke kaiapuni.

The role and economic benefits of glass powder on cement: Glass powder replaces cement, which can save 19,300 kW. , NOx15.1 t. If 20% of the 3.2 million tons of waste glass produced every year in our country is used to prepare concrete, there will be great ecological and economic benefits. The waste glass grinding machine produced by HCM Machinery is equipment for producing glass powder. It can process 80-600 waste glass powder to meet the processing needs of glass powder cement substrate. If you have relevant needs, please give us a call for details：hcmkt@hcmilling.com
