Nyika yedu inyika inonyanya kushandisa magirazi. Nekukura kuri kuita hupfumi nekukurumidza, kushandiswa kwemagirazi kuri kuwedzera zuva nezuva, uye kuraswa kwemagirazi emarara kwave dambudziko guru zvishoma nezvishoma. Chinhu chikuru chegirazi isilika inoshanda, saka mushure mekukuyiwa kuita upfu, rinogona kuva nekushanda kwakasimba uye rinogona kushandiswa semusanganiswa wekugadzira kongiri. Izvi hazvingogadzirisi dambudziko rekurasa magirazi emarara chete, asiwo zvinokurudzira kugadzirwa kwezvinhu zvekuvaka zvakasvibira uye zvisina njodzi kunharaunda.Michina yeHCMinyanzvi yekugadzira kugaya. Chigayo chekugaya chatinogadzira chinoshandiswa kukuya upfu hwegirazi husina kuchena. Nhasi ndichakuzivisai basa reupfu hwegirazi pasimende.

Nekuongorora simba rekumanikidzwa kwekongiri yakasanganiswa nehupfu hwegirazi uye mhedzisiro yekuongorora simende ne microscopic, zvinogona kugumiswa kuti kunyangwe CaO yehupfu hwegirazi ichigona kuita zvinoenderana nemvura, haina kusimba zvakanyanya. Saka, zvinogona kutariswa kuti hupfu hwegirazi hauna kuomarara kwe hydraulic. Kana huwandu hwehupfu hwegirazi huchisanganiswa huri 10%, semuenzaniso, silica inoshanda, alumina uye calcium hydroxide muhupfu hwegirazi zvinoita kuti zvigadzire calcium silicate ine alkalinity yakaderera. Silica inoshanda inogona zvakare kuita zvinoenderana necalcium silicate ine alkali yakawanda. Calcium silicate hydrate inoita kuti igadzire calcium silicate ine alkali yakaderera. Nekunge ichideredza huwandu hwecalcium hydroxide, chikamu checalcium silicate inogadzirwa, iyo inovandudza huwandu uye kusapinda kweslurry yakaoma; Inosangana nechinhu chinogadziriswa nesimende chinonzi hydration calcium hydroxide (Ca(OH)2) kugadzira mvura. Calcium silicate yakanyorova inoderedza huwandu hweCa(OH)2 mukongiri, inowedzera huwandu hwecalcium silicate yakanyorova, uye inovandudza simba rekongiri. Kana huwandu hweupfu hwegirazi hwasvika 20%, nekuti huwandu hwesimende hwaderera, mahydrate anokonzerwa ne hydration yesimende anodererawo, asi upfu hwegirazi hunosangana ne hydrate yesimende kuti hugadzire calcium silicate yakanyorova zvishoma. Kana huwandu hweupfu hwegirazi hwasvika 20%, simba rinoramba richifanana nekongiri. Kana huwandu hweupfu hwegirazi hukaramba huchiwedzera uye huwandu hwesimende huchidzikira zvishoma nezvishoma, huwandu hwezvigadzirwa zve hydration hunodzikira, uye upfu hwegirazi huchisangana ne hydrate yesimende. Kuwedzera kwe hydrate hakuna kukwana kutsiva kudzikira kwezvigadzirwa zve hydration kunokonzerwa nekuderera kwehuwandu hwesimende. Nokudaro, simba riri kuramba richidzikira. Zvinowanikwawo kuti kana huwandu hweupfu hwegirazi hwakawandisa, mitswe ichaonekwa.

Izvi zvinodaro nekuti kunyange huwandu hwesimende huchidzikira, kudiwa kwesilica inoshanda inobatsira mukuita kwemvura kunodzikirawo. Silica inoshanda yasara inosangana nezvinhu zvealkaline muupfu hwegirazi, zvichikonzera kukura kwekongiri mukati. Simende yakaoma ichatsemukawo yoburitsa mitswe mikuru, uye simba rekongiri richadzikirawo.

Mhedzisiro yeupfu hwegirazi pa simende:

(1) Simba rekudzvanya rekongiri rinoitwa kwemazuva makumi maviri nemasere rakagadzirwa nehupfu hwegirazi husina ruvara uye hupfu hwegirazi regirini hwakasanganiswa ne10% ne15% yesimende panzvimbo yesimende rakakwirira kupfuura rekongiri; kana chiyero chiri 20%, simba racho rakafanana nerekongiri. Zvichienzaniswa nekongiri; kana chiyero chiri 30% zvichikwira, simba rekudzvanya rekongiri rinoderera zvakanyanya.

(2) Kana pasina girazi reupfu rakaiswa, calcium hydroxide inonamira zvakanaka uye yakakura. Sezvo huwandu hwegirazi reupfu huchiwedzera, huwandu hwecalcium hydroxide hunoderera zvishoma nezvishoma uye crystallization inokura zvakanyanya.

(3) Kuwedzera upfu hwegirazi hwemavara akasiyana hakukanganisi zvikuru kusimba kwekongiri.

(4) Upfu hwegirazi hunoshandiswa kugadzira kongiri uye hune mhedzisiro yakanaka pakuchengetedza nharaunda.

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
