Swedish Thawj Fwm Tsav Tebchaws Anders Anderson tau hais ob peb hnub dhau los tias Sweden tab tom sib tham nrog Turkey ntawm kev koom nrog NATO thiab tos ntsoov yuav ntxiv dag zog rau kev koom tes nrog Turkey hauv kev ruaj ntseg thiab tiv thaiv kev ua phem.
Anderson tau tuav lub rooj sib tham sib tham nrog kev mus ntsib European Council Thawj Tswj Hwm Michelle Michel hauv Stockholm hnub ntawd.Anderson tau hais tias Sweden tab tom tham nrog Turkey txog kev koom nrog cov lus cog tseg thiab tos ntsoov yuav ntxiv dag zog rau kev sib raug zoo ntawm ob tog nrog Turkey, suav nrog kev koom tes hauv kev ruaj ntseg thiab counter. -kev ua phem.Nws hais tias Sweden yuav kawm qee qhov teeb meem uas tau tsa los ntawm Qaib Cov Txwv.
Yawg Michel tau hais rau lub rooj sib tham xov xwm tias nws ntseeg tias tsoomfwv Swedish tau ua qhov zoo thiab ua cov kauj ruam tsim nyog kom ncav cuag qhov kev daws teeb meem.
Sweden thiab Finland tau xa lawv daim ntawv thov mus rau NATO Secretary General Jens Stoltenberg.Raws li kev pom zoo, NATO yuav tsum lees txais cov tswv cuab tshiab los ntawm "kev pom zoo" ntawm 30 tus tswv cuab.
Tus Thawj Fwm Tsav Tebchaws Turkish Mevrut Cavusoglu tau hais tias Qaib ntxhw tsuas pom zoo ua haujlwm nrog Sweden yog tias Sweden thiab Finland tau ua tiav daim ntawv cog lus kom tsis txhob txhawb kev ua phem thiab tshem tawm cov kev txwv rau kev xa tawm cov cuab yeej tiv thaiv mus rau Qaib Cov Txwv, Turkish xov xwm tshaj tawm. NATO tham nrog Finland.
Kev cuam tshuam los ntawm qhov teeb meem thoob ntiaj teb tsis hloov pauv, cov khoom siv thiab tus nqi ntawm cov neeg ua haujlwm thoob ntiaj teb thaum ntxov-lub zog tseem tsis paub meej.
Tus neeg saib xyuas lub zog thaum ntxov yog cov khoom sib xyaw uas ua kom lub zog thaum ntxov ntawm cov pob zeb thiab tsis muaj kev cuam tshuam rau lub zog tom qab.Tus neeg sawv cev lub zog thaum ntxov tuaj yeem ua kom cov txheej txheem hardening ntawm pob zeb ntawm qhov qub thiab tsis tshua muaj qhov kub thiab txias (tsis qis dua -5 ℃) , thiab yog siv rau hauv kev tsim kho lub caij ntuj no thiab kev kho thaum muaj xwm ceev.
Tus neeg saib xyuas lub zog thaum ntxov yog hais txog cov khoom sib xyaw uas tuaj yeem ua kom cov pob zeb ua kom muaj zog thaum ntxov.Lub ntsiab mechanism ntawm kev txiav txim yog kom ceev cov hydration tus nqi ntawm cov cement thiab ua kom cov crystallization thaum ntxov thiab nag lossis daus ntawm cov khoom hydration.Lub luag haujlwm tseem ceeb yog ua kom luv luv ntawm cov pob zeb. thiab lub sij hawm txij nkawm, ua kom cov kev tsim kho kom zoo, thiab txhim kho cov formwork turnover tus nqi.
1. Tus neeg saib xyuas lub zog thaum ntxov yog tsim rau cov khoom siv ua kom sov thiab cov pob zeb ua haujlwm nrog lub zog thaum ntxov rau kev tsim kho ntawm chav tsev kub, qhov kub thiab txias tsis qis tshaj -5 ° C.Early lub zog tus neeg sawv cev yuav tsum tsis txhob siv nyob rau hauv siab. kub ib puag ncig.
2. Cov tshuaj lom neeg uas tsim kev puas tsuaj rau tib neeg lub cev lossis ua paug rau ib puag ncig tom qab kev sib xyaw ua vaj tse yuav tsum tsis txhob siv los ua cov tshuaj muaj zog thaum ntxov. thiab zaub mov tiv tauj engineering.Ammonium nitrate yuav tsum tsis txhob siv rau hauv chaw ua haujlwm, tsev nyob thiab lwm yam kev tsim kho.
Cov neeg sawv cev thaum ntxov muaj zog feem ntau suav nrog cov ntsev inorganic (chlorine ntsev, phosphates) thiab cov organic amines, nrog rau cov organic-inorganic compounds.
Chloride ntsev thaum ntxov lub zog cov neeg ua haujlwm feem ntau suav nrog calcium chloride, potassium chloride, aluminium chloride thiab ferric chloride, ntawm cov calcium chloride yog cov siv dav tshaj plaws.Calcium chloride yog cov hmoov dawb dawb, thiab nws cov tshuaj tsim nyog yog 0.5% mus rau 1.0% ntawm cov cement. zoo, uas tuaj yeem nce 3d lub zog ntawm pob zeb los ntawm 50% mus rau 10% thiab 7d lub zog los ntawm 20% mus rau 40%.
Qhov loj tshaj qhov tsis zoo ntawm kev siv calcium chloride ua tus neeg sawv cev muaj zog thaum ntxov, muaj Cl-ions, yog tias nws yuav corrode cov hlau thiab ua rau pob zeb tawg, txhawm rau tiv thaiv cov nyhuv corrosion ntawm calcium chloride ntawm steel tuav, calcium chloride thiab sodium nitrite. (NaNO2) feem ntau siv ua ke.
Sulfate thaum ntxov-lub zog cov neeg ua haujlwm feem ntau suav nrog sodium sulfate, calcium thiosulfate, aluminium sulfate, potassium aluminium sulfate, thiab sodium sulfate yog siv ntau dua.Sodium sulfate yog cov hmoov dawb. Feem ntau, qhov ntau npaum li cas ntawm admixture yog 0.5% ~ 2.0%. Thaum cov tshuaj sib xyaw ua ke yog 1% ~ 1.5%, lub sijhawm kom ncav cuag 70% ntawm cov pob zeb tsim lub zog tuaj yeem luv luv los ntawm ib nrab.
Sodium sulfate tsis muaj corrosive rau steel tuav thiab yog tsim rau cov pob zeb uas chloride ntsev tsis raug tso cai.Txawm li cas los xij, vim nws cuam tshuam nrog calcium hydroxide los ua kom muaj zog alkali NaOH, txhawm rau tiv thaiv cov tshuaj tiv thaiv ntawm alkali aggregates, sodium sulfate yog nruj me ntsis txwv. txwv tsis pub rau cov pob zeb uas muaj cov active aggregates. Lub pob zeb nto "froze".
Organic amine thaum ntxov-lub zog cov neeg ua haujlwm feem ntau suav nrog triethanolamine, triisopropanolamine, thiab lwm yam, ntawm cov triethanolamine yog tus neeg sawv cev zoo tshaj plaws thaum ntxov.
Triethanolamine yog cov xim tsis muaj xim lossis lub teeb daj oily kua uas yog alkaline thiab yooj yim soluble hauv dej.Ntxiv 0.02% mus rau 0.05% ntawm cov cement zoo tuaj yeem txhim kho lub zog thaum ntxov ntawm cov pob zeb.Triethanolamine muaj qhov cuam tshuam me ntsis ntawm cov pob zeb, ntau dhau yuav ua rau mob hnyav. thiab txo cov pob zeb ua kom muaj zog, yog li cov tshuaj yuav tsum tau tswj nruj me ntsis.

Tsoomfwv Meskas Cov Nyiaj Txiag tau hais tias lawv yuav sib tham nrog G7 cov thawj coj txog tus nqi cap thiab tariffs ntawm Lavxias teb sab roj raws li ib tug lwm txoj rau ib tug embargo uas yuav ua rau lub khw muab, txwv tus nqi spikes thiab txo cov nyiaj tau los ntawm Lavxias teb sab, Reuters qhia.
EU cov thawj coj txawv teb chaws ntsib hauv Brussels.Lub rooj sib tham tsis pom zoo rau qhov thib rau ntawm kev rau txim, suav nrog kev lag luam roj rau Russia, vim kev tawm tsam los ntawm Hungary.
EU tus neeg sawv cev siab rau kev ua haujlwm txawv teb chaws thiab kev ruaj ntseg txoj cai tau hais hauv lub rooj sib tham tom qab lub rooj sib tham hais tias lub rooj sib tham ua tsis tau raws li kev pom zoo ntawm qhov kev pom zoo zaum kawg ntawm kev rau txim zaum thib rau, thiab cov tswvcuab cov neeg sawv cev mus rau EU yuav txuas ntxiv kev sib tham. Cov nom tswv txawv teb chaws kuj tau sim ua kom tiav qhov kev pom zoo ntawm kev txwv roj. ntsib cov teeb meem zoo sib xws.Nws hais tias Hungary txoj haujlwm yog nyob ntawm kev lag luam es tsis yog kev xav txog nom tswv.
Hungary yog vam khom rau Russia rau lub zog, nrog ntau tshaj 60% ntawm nws cov roj thiab 85% ntawm nws natural gas los ntawm Russia.
Ob peb hnub dhau los, European Commission tau xa mus rau qhov thib rau ntawm kev nplua tawm tswv yim tawm tsam Russia, suav nrog kev txwv tag nrho ntawm Lavxias cov roj ntshuam los ntawm qhov kawg ntawm lub xyoo no.Hungary tau tawm tsam tam sim ntawd thiab hais tias nws xav tau nyiaj ntau heev los ntawm EU los them nws cov kev poob los ntawm tso tseg Russia roj.
Kev cuam tshuam los ntawm cov xwm txheej geopolitical, tus nqi ntawm tus neeg sawv cev lub zog thaum ntxov yuav tsum nce siab nyob rau ob peb hnub tom ntej.
Cov neeg siv khoom hauv Asmeskas tau foob foob Mars hauv California lub tsev hais plaub dhau los rau hnub Thursday, thov Skittles muaj titanium dioxide ntau dhau (E171).Puas titanium dioxide puas tsim kev puas tsuaj rau lub cev?
