Nyika yedu "mutengi mukuru wezviwanikwa" wegirazi.Nekukurumidza kukura kwehupfumi, kushandiswa kwegirazi kuri kuwedzera zuva nezuva, uye kuraswa kwemarara kwegirazi kwave kuita nyaya ine minzwa zvishoma nezvishoma.Chinhu chikuru chegirazi chinoshanda silica, saka mushure mekugayiwa kuita upfu, inogona kuita pozzolanic chiitiko uye inogona kushandiswa seyakasanganiswa kugadzira kongiri.Izvi hazvigone chete kugadzirisa dambudziko rekurasa girazi remarara, asiwo kukurudzira kuvandudzwa kwezvinhu zvakasvibirira uye zvakatipoteredza zvekuvaka.HCM Machineryinogadzira guyo.Chigayo chatinogadzira midziyo inoshandiswa kukuya tsvina yegirazi poda.Nhasi ndichakuzivisai basa regirazi poda pane simende.

Nekuongorora iyo yekumanikidza simba bvunzo yekongiri yakasanganiswa negirazi poda uye microscopic yekuongorora mhedzisiro yesamende paste, zvinogona kugumiswa kuti kunyangwe iyo CaO yegirazi poda inogona kuita nemvura, haina kusimba.Naizvozvo, zvinogona kutariswa kuti girazi poda haina hydraulic kuomarara.Kana iyo yekusanganiswa yegirazi poda iri 10%, semuenzaniso, iyo inoshanda silica, alumina uye calcium hydroxide mugirazi poda inoita kuti iite yakaderera-alkalinity hydrated calcium silicate.Iyo inoshanda silica inogonawo kuita nepamusoro-alkalinity hydrated calcium silicate.Calcium silicate hydrate inobata kuburitsa yakaderera-alkali calcium silicate hydrate.Nepo kuderedza calcium hydroxide content, chikamu che hydrated calcium silicate inogadzirwa, iyo inovandudza kuwanda uye kusagadzikana kweiyo yakaoma slurry;inopindirana necement hydration product calcium hydroxide (Ca (OH) 2) kugadzira mvura Hydrated calcium silicate inoderedza zvinyorwa zveCa (OH) 2 mukrete, inowedzera zvinyorwa zve hydrated calcium silicate, uye inovandudza simba rekrete. girazi rehupfu rinosvika 20%, nokuti simenti inoderera inoderera, iyo hydrates inogadzirwa nesamende hydration inodererawo, asi girazi poda inopindirana nesamende hydrates kuti iite zvishoma hydrated calcium silicate.Kana huwandu hwegirazi hupfu hunosvika 20%, simba. ichiri kufananidzwa nebenchmark kongiri.Kana huwandu hwegirazi hupfu huchiramba huchiwedzera uye simenti yemukati inoderera zvishoma nezvishoma, huwandu hwezvigadzirwa zve hydration hunova hushoma uye hushoma, uye girazi poda inopindirana nesamende hydrates Iyo yakawedzera hydrate haina kukwana kubhadhara kuderera kwezvigadzirwa zve hydration zvinokonzerwa ne kuderera kwe simenti.Nokudaro, simba racho riri kuramba richidzikira.Inowanikwawo kuti kana huwandu hwegirazi hupfu hwakanyanya, kuputika kuchaonekwa.

Izvi zvinodaro nekuti nepo huwandu hwesimende hwakadzikiswa, kudiwa kweiyo inoshanda silica inotora chikamu muiyo hydration reaction inoderedzwa zvakare.Iyo yakasara inoshandiswa silica inopindirana neine alkaline zvinhu muupfu hwegirazi, zvichiita kuti mukati mekuwedzera kwekrete.Iyo yakaomeswa simende paste ichatsemukawo uye kugadzira mitswe yakakura, uye kusimba kwekongiri kuchaderedzwawo.

Mhedzisiro yegirazi poda pane simenti:

(1) Simba rekumanikidza remazuva makumi maviri nemasere rekongiri rakagadzirwa negirazi risina ruvara rakajeka poda uye girazi regirini poda yakasanganiswa ne10% uye 15% yesamende panzvimbo yesimende yakakwirira kupfuura iyo yebhenji kongiri;apo dosage iri 20%, simba racho rakafanana neiyo yebhenji kongiri.Kuenzaniswa nekongiri;apo dosage iri 30% uye pamusoro, iyo yekumanikidza simba rekongiri inoderera zvakanyanya.

(2) Kana pasina girazi poda inowedzerwa, calcium hydroxide inopenya zvakanaka uye yakakura muhukuru.Sezvo huwandu hwegirazi hupfu hunowedzera, zvinyorwa zve calcium hydroxide zvishoma nezvishoma zvinoderera uye crystallization inowedzera uye yakaipa.

(3) Kuwedzera girazi poda yemavara akasiyana hakuna kukanganisa kukuru pakusimba kwekongiri.

(4) Girazi poda inoshandiswa kugadzira kongiri uye ine hukuru hukuru hwemagariro.

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
