Abstract:
Concrete chinhu chakakosha chekuvaka chinoshandiswa zvakanyanya mukuvaka nekuda kwesimba rayo, kusimba uye kuita zvakasiyana. Akasiyana-siyana ekuwedzera anoshandiswa kuvandudza kongiri zvivakwa uye kugadzirisa chaiwo matambudziko ane chekuita nekugadzirwa kwayo uye mashandisiro. Chinowedzera chekufarira kukuru ndeye calcium formate, komboni ine yakasarudzika zvivakwa zvinobatsira kuvandudza kongiri zvivakwa.
suma:
Concrete chinhu chakaumbwa chinoumbwa nesamende, aggregate, mvura uye admixtures uye ndiwo musimboti wekuvaka kwemazuva ano. Mukutsvaga zvitsva zvinowedzera kuwedzera kongiri zvivakwa, calcium formate, komboni yakabva kune formic acid uye calcium carbonate, yakaongororwa. Ichi chinyorwa chine chinangwa chekuwana kunzwisisa kwakadzama kwemhedzisiro yecalcium fomati pakongiri, kujekesa zvimiro zvayo, zvakanakira uye zvakasiyana mashandisirwo.
Zvinhu zve calcium formate:
Chemical composition:
Calcium formate imunyu unonyungudika mumvura unoumbwa necalcium ions (Ca2+) uye formate ions (HCOO-).
Yayo kemikari formula ndeye Ca(HCOO)2.
Solubility:
Calcium formate inoratidza kunyungudika kwakanyanya mumvura, izvo zvinofambisa kupararira kwayo kweyunifomu mukati memusanganiswa wekongiri.
Hydration process:
Munguva ye hydration process, calcium formate inobatsira pakuumbwa kwekuwedzera hydration zvigadzirwa zvinokanganisa microstructure yekongiri.
Zvakanakira zveCalcium Formate muKongiri:
Yakakurumidza kuseta nguva:
Calcium formate inoshanda seanomhanyisa, kupfupisa nguva yekumisikidza kongiri. Izvi zvinonyanya kubatsira mumamiriro ekunze anotonhora apo kunonoka kugadzirisa kunogona kupa matambudziko.
Kusimbisa:
Kuvapo kwecalcium formate kunowedzera iyo yekutanga uye yekupedzisira yekumanikidza simba rekongiri, nekudaro inovandudza kuita kwemaitiro.
Deredza kubuda ropa nekuparadzana:
Calcium formate inobatsira kuderedza kubuda ropa uye kupatsanurwa, kukurudzira kufanana mumusanganiswa wekongiri.
Kuvandudza machinability:
Concrete inobatanidza calcium formate inowanzoratidza kushanda kwakavandudzwa, zvichiita kuti zvive nyore kubata uye kuisa panguva yekuvaka.
Kuderedza Kukuvara KweFrost:
Mumamiriro ekunze anotonhora, kuwedzera kwecalcium formate kunogona kubatsira kudzikisira kukuvadzwa kwechando nekukasira kuseta nguva uye kuderedza kusadzivirirwa kwekongiri kuti iite chando.
Kushandiswa kwecalcium formate mukongiri:
Kudira kwekongiri yekutonhora kwemamiriro ekunze:
Calcium formate inowanzoshandiswa mukutonhora kwemamiriro ekunze kongiri yekuisa kurwisa zvakaipa zvinokonzeresa tembiricha yakaderera pane yekumisikidza uye kurapa maitiro.
Kugadzirisa nekukurumidza:
Mune zvikumbiro zvinoda kugadziriswa nekukurumidza, sekugadziriswa kwekukurumidzira kana kugadzirisa kwezvivakwa, kushandisa calcium formate kunogona kukurumidzira nguva dzekuvaka.
Precast kongiri kugadzirwa:
Iyo inokurumidza kuseta nguva uye kusimudzira kwesimba kwakabatana necalcium fomati inoita kuti ive yakakodzera precast kongiri kugadzirwa uko nekukurumidza kutendeuka nguva kwakakosha.
High performance concrete:
Calcium formate inobatsira kuburitsa yakakwirira-inoita kongiri ine yakawedzera kusimba uye simba zvivakwa, zvichiita kuti ive yakakodzera kune yakakosha mapurojekiti ezvivakwa.
Matambudziko nekufunga:
Zvinotemerwa nemitengo:
Nepo calcium formate ine zvakawanda zvakanaka, mutengo wayo unogona kunge uri chinhu chekufunga nezvako mubhajeti reprojekiti.
Dose Optimization:
Huwandu hwakakwana hwecalcium fomati hunofanirwa kutariswa zvichienderana nezvinodiwa zveprojekiti, uchifunga nezvezvinhu zvakaita semisanganiswa dhizaini, mamiriro ezvakatipoteredza uye inodiwa kongiri zvivakwa.
mukupedzisa:
Muchidimbu, calcium formate inobuda sechinhu chakakosha chekuwedzera mumunda wekongiri tekinoroji, ichipa nhevedzano yezvakanakira zvinogadzirisa zvinowanzoitika zvinosangana nekugadzira kongiri uye kushandisa. Kubva pakukurumidza kuseta nguva kusvika pakuvandudza simba uye kushanda, calcium formate inogoneka zvivakwa inoita kuti ive inovimbisa mumiriri kune akasiyana siyana ekuvaka. Sezvo tsvagiridzo ichienderera mberi uye tekinoroji ichifambira mberi, kubatanidza calcium formate mumisanganiswa yekongiri inogona kuita basa rakakosha mukuumba ramangwana rezvivakwa zvekuvaka uye maitiro.
