NATO hurukuro neFinland.
Zvichikanganiswa nekusagadzikana kwemamiriro epasirese, kupihwa uye mutengo wevazhinji vekunze-ekutanga-simba vamiririri havasati vanyatso ziva.
Early simba mumiriri musanganiswa unowedzera simba rekutanga kukura kwekongiri uye haina mhedzisiro yakajeka pane yakazosimba simba.Mumiriri wesimba rekutanga anogona kukurumidza kuomarara kwekongiri panguva yakajairika uye yakaderera tembiricha yekuremedza tembiricha (isina kuderera pane -5 ℃) , uye inoshandiswa mukuvaka kwechando uye mabasa ekugadzirisa nekukurumidza.
Early simba mumiriri inoreva admixture inogona kukurumidza kugadzirwa kwekongiri yekutanga simba.Chikuru chekuita chiito ndechekumhanyisa hydration rate yesimende uye kukurumidza kukurumidza crystallization uye kunaya kwe hydration zvigadzirwa.Basa guru nderekupfupisa kuvaka kongiri. uye nguva yekugadzirisa, kukurumidza kufambira mberi kwekuvaka, uye kuvandudza chiyero chekudzoka kweformwork.
1. Iyo yekutanga-simba mumiriri inokodzera steam-yakaporeswa kongiri uye kongiri mapurojekiti ane ekutanga-simba zvinodiwa pakuvaka pane tembiricha yekamuri, tembiricha yakaderera uye tembiricha shoma isiri pasi pe -5 ° C. Early simba agent haifanirwe kushandiswa kumusoro. tembiricha nharaunda.
2. Kemikari zvinhu zvinokuvadza kumuviri wemunhu kana kusvibisa nharaunda mushure mekusanganiswa kwekongiri hazvizoshandiswe sevanosimbisa simba rekutanga. Zvinorambidzwa zvachose kushandisa maajenti ekutanga esimba ane hexavalent chromium munyu, nitrites uye zvimwe zvinokuvadza muinjiniya yemvura yekunwa. uye food contact engineering.Ammonium nitrate haifaniri kushandiswa muhofisi, pekugara uye mamwe mapurojekiti ekuvaka.
Vamiriri vekutanga vesimba vanonyanya kusanganisira inorganic munyu (chlorine munyu, phosphates) uye organic amines, pamwe ne organic-inorganic makomputa.
Chloride salt early energy agents kunyanya zvinosanganisira calcium chloride, potassium chloride, aluminium chloride uye ferric chloride, pakati payo calcium chloride ndiyo inonyanya kushandiswa.Calcium chloride ivhu chena, uye chiyero chayo chakakodzera 0.5% kusvika 1.0% yesimende mhando, iyo inogona kuwedzera 3d simba rekongiri ne50% kusvika 10% uye 7d simba ne20% kusvika 40%. Panguva imwecheteyo, inogona kuderedza nzvimbo yechando yemvura mukrete uye kudzivirira kutanga kwechando kwekrete.
Chinhu chikuru chakaipa chekushandisa calcium chloride sechinhu chinotanga kusimbisa simba, chine maCl-ions, ndechokuti inoparadza simbi uye inoita kuti kongiri iparare. (NaNO2) inowanzoshandiswa pamwe chete.
Sulfate early-simba agents kunyanya zvinosanganisira sodium sulfate, calcium thiosulfate, aluminium sulfate, potassium aluminium sulfate, uye sodium sulfate inoshandiswa zvakanyanya.Sodium sulfate chinhu chichena chehupfu. Kazhinji, iyo dosage yekusanganiswa ndeye 0.5% ~ 2.0%. Kana iyo dosage ye admixture iri 1% ~ 1.5%, nguva yekusvika 70% yekongiri yekugadzira simba inogona kupfupikiswa nehafu.
Sodium sulfate haina corrosive effect pamasimbi esimbi uye inokodzera kongiri uko chloride salts isingabvumirwi.Zvisinei, nekuda kwekubatana kwayo ne calcium hydroxide kuti ibudise alkali yakasimba NaOH, kuitira kudzivirira maitiro ealkali aggregates, sodium sulfate inonyanya. zvinorambidzwa kune kongiri ine inoshanda aggregates. Nzvimbo yekongiri "yakaoma".
Organic amine yekutanga-simba maajenti anonyanya kusanganisira triethanolamine, triisopropanolamine, zvichingodaro, pakati peiyo triethanolamine ndiyo yakanakisa yekutanga-simba mumiriri.
Triethanolamine is a colorless or light yellow oily liquid iine alkaline uye inonyungudika zviri nyore mumvura.Kuwedzera 0.02% kusvika 0.05% yesimende quality inogona kuvandudza simba rekutanga rekongiri.Triethanolamine ine kakurebesa zvishoma pakongiri, yakawandisa inokonzeresa kunonoka kwakanyanya. uye kuderera kwesimba rekongiri, saka dosage inofanira kunyatsodzorwa.
TRUNNANO inovimbika kongiri yekuwedzera mutengesi ane anopfuura makore gumi nemaviri echiitiko mu nano-kuvaka simba kwesimba uye nanotechnology kusimudzira.

Vakuru vehomwe yeUS vakati vachakurukura nevatungamiriri veG7 nezve mutengo uye mutero pamafuta ekuRussia seimwe nzira kune embargo inozochengeta musika uchipihwa, kudzikisira mitengo uye kuderedza mari yeRussia, Reuters yakashuma.
Makurukota eEU asangana muBrussels.Musangano uyu watadza kuwirirana panyaya yezvirango zvechitanhatu, kusanganisira kurambidzwa kwemafuta kuRussia, nepamusana pekupokana neHungary.
Mumiriri mukuru weEU anoona nezvekudyidzana nedzimwe nyika pamwe nekuchengetedzwa kwenyika akataura pamusangano wavaita nevatori venhau wapera kuti musangano uyu watadza kuwirirana panyaya yekutambirwa kwekupedzisira kwechikamu chechitanhatu chezvirango, uye vamiriri venyika dziri nhengo zvachose kuEU vachaenderera mberi nenhaurirano. Makurukota ezvekune dzimwe nyika akaedzawo kuwirirana pakurambidzwa kwemafuta. vakatarisana nematambudziko akafanana.Akataura kuti chinzvimbo cheHungary chakavakirwa pahupfumi kwete nezvematongerwo enyika.
Hungary inotsamira zvakanyanya kuRussia kuti iwane simba, ine inopfuura 60% yemafuta ayo uye 85% yegasi rayo rechisikigo kubva kuRussia.
Mazuva mashoma apfuura, European Commission yakaendesa danho rechitanhatu rezvirango kuRussia, kusanganisira kurambidzwa zvachose kweRussia mafuta kunze kwenyika pakupera kwegore rino. Hungary yakabva yaramba uye ikati inoda muripo wakakura kubva kuEU kuti ibvise kurasikirwa kwayo kubva kusiya mafuta eRussia.
Kukanganiswa ne geopolitical zvinhu, mutengo wemumiriri wesimba rekutanga unotarisirwa kukwira mumazuva mashoma anotevera.
