He aha ka hana o ka hoʻohui ʻana i ka pauka aniani i ka wā hana sima?

ʻO ko mākou ʻāina he "mea kūʻai waiwai nui" o ke aniani.Me ka wikiwiki o ka hoʻokele waiwai, ke hoʻonui nei ka ʻai aniani i kēlā me kēia lā, a ua lilo ka hoʻolei ʻana i ke aniani ʻōpala i mea ʻoi loa.ʻO ka mea nui o ke aniani he silica ikaika, no laila, ma hope o ka lepo ʻana i ka pauka, hiki ke loaʻa ka hana pozzolanic a hiki ke hoʻohana ʻia i mea hoʻohui e hoʻomākaukau ai i ke kaʻa.ʻAʻole hiki i kēia ke hoʻoponopono wale i ka pilikia o ka hoʻokuʻu ʻana i ke aniani ʻōpala, akā hoʻoikaika pū i ka hoʻomohala ʻana i nā mea kūkulu hale ʻōmaʻomaʻo a me ke kaiapuni.Mīkini HCMhe mea hana wili palaoa.ʻO ka wili wili a mākou e hana ai, ʻo ia nā mea hana e wili ai i ka pauka aniani ʻōpala.I kēia lā, e hōʻike aku wau iā ʻoe i ke kuleana o ka pauka aniani ma ka sima.

 

Ma ke kālailai ʻana i ka hoʻāʻo ʻana o ka ikaika compressive o ke kaila 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 hana me ka wai, ua nāwaliwali loa.No laila, hiki ke noʻonoʻo ʻia ʻaʻohe paʻakikī hydraulic.Ke 10% ka nui o ka hui ana o ka pauda aniani, no ka la'ana, ua hana ka silica ikaika, alumina a me ka calcium hydroxide i loko o ka pauda aniani e hana i ka silicate calcium hydrated ha'aha'a.Hiki nō hoʻi i ka silica ʻeleu ke hana pū me ka silicate calcium hydrated kiʻekiʻe.Hoʻopili ʻia ka hydrate calcium silicate no ka hana ʻana i ka wai calcium silicate haʻahaʻa.ʻOiai e hōʻemi ana i ka nui o ka calcium hydroxide, hana ʻia kahi hapa o ka calcium silicate hydrated, e hoʻomaikaʻi ai i ka nui a me ka impermeability o ka slurry paʻakikī;e hoʻoemi ana ia me ka huahana hydration ciment calcium hydroxide (Ca(OH)2) e hoʻohua i ka wai. hiki i ka 20% ka pauka aniani, no ka emi ʻana o ka ʻike cement, emi pū ka hydrates i hana ʻia e ka hydration sima, akā hoʻololi ka pauka aniani me nā hydrates sima e hana ai i ka calcium silicate. ua like ia me ka benchmark concrete.Ke hoʻomau nei ka hoʻonui ʻana o ka pauka aniani a hoʻemi mālie ka ʻike o ka sima, e emi iho ka nui o nā huahana hydration, a hoʻopili ka pauka aniani me nā hydrates sima. ka emi ʻana o nā mea sima.No laila, ke emi nei ka ikaika a emi iho.Ua ʻike ʻia nō hoʻi ke ʻoi aku ka nui o ka pauda aniani, e ʻike ʻia nā māwae.

He aha ke kuleana o ka hoʻohui ʻana i ka pauka aniani i ka wā hana sima

ʻO kēia no ka mea ʻoiai e hoʻemi ʻia ka nui o ka sima, ua hoʻemi ʻia ke koi no ka silica ikaika e komo ana i ka hopena hydration.Hoʻopili ke koena silica ikaika me nā mea alkaline i loko o ka pauka aniani, e hoʻonui ai i loko o ka ʻeke.ʻO ka paʻipaʻi sima paʻakikī hoʻi e māhā a hoʻohua i nā māwae nui aʻe, a e hoʻemi pū ʻia ka ikaika o ka pahu.

 

Ka hopena o ka pauka aniani ma ka sima:

(1) ʻO ka ikaika compressive 28-lā o ke kaʻa i hoʻomākaukau ʻia me ka pauka aniani aniani ʻole a me ka pauka aniani ʻōmaʻomaʻo i hui pū ʻia me 10% a me 15% o ka sima ma kahi o ka sima ua ʻoi aku ka kiʻekiʻe ma mua o ka benchmark concrete;i ka 20% o ka dosage, ua like ka ikaika me ko ka benchmark concrete.Hoʻohālikelike ʻia me ke koneki;i ka 30% a ma luna o ka dosage, e emi nui ana ka ikaika compressive o ke konima.

 

(2) Ke hoʻokomo ʻole ʻia ka pauda aniani, ʻoi aku ka maikaʻi o ka calcium hydroxide a ʻoi aku ka nui.Ke piʻi aʻe nei ka nui o ka pauka aniani, e emi mālie ka ʻike o ka calcium hydroxide a ʻoi aku ka ʻino a ʻoi aku ka maikaʻi o ka crystallization.

 

(3) ʻO ka hoʻohui ʻana i ka pauka aniani o nā waihoʻoluʻu ʻokoʻa ʻaʻole ia he hopena nui i ka ikaika o ke kaʻa.

 

(4) Hoʻohana ʻia ka pauka aniani no ka hoʻomākaukau ʻana i ka lāʻau a loaʻa nā hopena kaiaola.

 

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
