UNdunankulu waseSweden u-Anders Anderson uthe ezinsukwini ezimbalwa ezedlule ukuthi iSweden ixoxisana neTurkey ngokujoyina i-NATO futhi ibheke phambili ekuqiniseni ukubambisana neTurkey kwezokuphepha kanye nokulwa nobuphekula.
U-Anderson ubambe isithangami sabezindaba esihlanganyelwe noMongameli woMkhandlu waseYurophu uMichelle Michel eStockholm ngalolo suku. U-Anderson uthe iSweden ixoxisana neTurkey ngokujoyina lesi sivumelwano futhi ubheke ngabomvu ukuqinisa ubudlelwano bamazwe amabili neTurkey, okubandakanya ukubambisana emikhakheni yezokuphepha kanye nekhawunta. -ubuphekula.Uthe iSweden izofunda ezinye zezinto eziphakanyiswe yiTurkey.
UMnu Michel utshele isithangami sabezindaba ukuthi ukholelwa ukuthi uhulumeni waseSweden uthatha izinyathelo ezinhle futhi uthatha izinyathelo ezidingekayo ukuze kufinyelelwe isixazululo.
ISweden neFinland zithumele ngokusemthethweni izicelo zazo kuNobhala-Jikelele we-NATO uJens Stoltenberg.Ngaphansi kwesivumelwano, i-NATO kufanele ivume amalungu amasha "ngemvume efanayo" yamalungu angu-30.
UNgqongqoshe Wezangaphandle waseTurkey uMevrut Cavusoglu uthe iTurkey izovuma kuphela ukusebenzisana neSweden uma iSweden neFinland befinyelela esivumelwaneni esibhaliwe sokuyeka ukusekela ubuphekula futhi yehlise imingcele yokuthunyelwa kwemishini yezokuvikela eTurkey, kubika abezindaba baseTurkey. Izingxoxo ze-NATO neFinland.
Bethintwe isimo samazwe ngamazwe esiguquguqukayo, ukuhlinzekwa kanye nentengo yama-ejenti wamazwe ngamazwe wokuqinisa amandla kusenesikhathi akuqinisekile kakhulu.
I-ejenti yamandla yangaphambi kwesikhathi iyinhlanganisela esheshisa ukuthuthukiswa kwamandla okuqala kakhonkolo futhi ayinawo umphumela osobala emandleni akamuva.I-ejenti yamandla yakuqala ingasheshisa inqubo yokuqina kakhonkolo ngezinga lokushisa elivamile neliphansi lokushisa (hhayi ngaphansi kuka -5℃) , futhi isetshenziselwa ukwakhiwa kwasebusika kanye nemisebenzi yokulungisa izimo eziphuthumayo.
I-ejenti yamandla yangaphambi kwesikhathi ibhekisela ekuxubeni okungasheshisa ukuthuthukiswa kwamandla kakhonkolo okuqala.Indlela eyinhloko yesenzo ukusheshisa izinga lokugeleza kukasimende nokusheshisa ukucwebezela kwekristalu kanye nemvula yemikhiqizo ye-hydration.Umsebenzi oyinhloko ukufinyeza ukwakhiwa kukasimende. kanye nesikhathi sokuyilungisa, kusheshiswe inqubekelaphambili yokwakha, futhi kuthuthukise izinga lokushintshwa kwe-formwork.
1. I-ejenti yamandla okuqala ifanele amaphrojekthi kakhonkolo kanye nekhonkrithi aphekwe ngesitimu anezidingo zamandla kusenesikhathi ukuze kwakhiwe ekamelweni lokushisa, izinga lokushisa eliphansi kanye nezinga lokushisa eliphansi elingekho ngaphansi kuka -5 °C.I-ejenti yamandla yangaphambi kwesikhathi akufanele isetshenziswe phezulu. izinga lokushisa imvelo.
2. Izinto zamakhemikhali eziyingozi emzimbeni womuntu noma ezingcolisa imvelo ngemva kokuxuba ukhonkolo akufanele zisetshenziswe njengama-ejenti aqinisa amandla kusenesikhathi. Kwenqatshelwe ngokuphelele ukusebenzisa ama-ejenti wamandla okuqala aqukethe usawoti we-chromium oyi-hexavalent, nitrites nezinye izakhi eziyingozi kubunjiniyela bamanzi okuphuza. kanye nobunjiniyela bokuxhumana nokudla.I-Ammonium nitrate ngeke isetshenziswe ehhovisi, ezindaweni zokuhlala nakweminye imisebenzi yokwakha.
Ama-ejenti wamandla okuqala ikakhulukazi afaka usawoti we-inorganic (usawoti we-chlorine, ama-phosphates) nama-amine aphilayo, kanye nezinhlanganisela ze-organic-inorganic.
I-Chloride esetshenziswa kakhulu usawoti kasawoti wakudala ihlanganisa i-calcium chloride, i-potassium chloride, i-aluminium chloride ne-ferric chloride, okukhona phakathi kwayo i-calcium chloride esetshenziswa kakhulu. izinga, elingakhuphula amandla we-3d kakhonkolo ngo-50% kuya ku-10% kanye namandla we-7d ngo-20% kuya ku-40%.
Ububi obukhulu bokusebenzisa i-calcium chloride njenge-ejenti yamandla yokuqala, equkethe ama-Clions, ukuthi izogqwala insimbi futhi ibangele ukuqhekeka kukakhonkolo. (I-NaNO2) ivame ukusetshenziswa ngokuhlanganiswa.
I-sulfate yamandla okuqala ngokuyinhloko ihlanganisa i-sodium sulfate, i-calcium thiosulfate, i-aluminium sulfate, i-potassium aluminium sulfate, kanye ne-sodium sulfate isetshenziswa kakhulu.I-sodium sulfate iyimpuphu emhlophe. Ngokuvamile, umthamo we-admixture ngu-0.5% ~ 2.0%. Lapho isilinganiso se-admixture singu-1% ~ 1.5%, isikhathi sokufinyelela ku-70% wamandla wokuklama ukhonkolo singafinyezwa cishe ngesigamu.
I-sodium sulfate ayinawo umthelela wokugqwala emigoqweni yensimbi futhi ifanele ukhonkolo lapho usawoti we-chloride ungavunyelwe.Nokho, ngenxa yokusebenzisana kwayo ne-calcium hydroxide ukukhiqiza i-alkali eqinile i-NaOH, ukuze kuvinjelwe ukusabela kwe-alkali aggregates, i-sodium sulfate iqinile. akuvunyelwe ukhonkolo oqukethe izingxenye ezisebenzayo. Indawo ewukhonkolo “yabanda”.
I-Organic amine-early-power agents ikakhulukazi i-triethanolamine, i-triisopropanolamine, njll., phakathi kwayo i-triethanolamine iyi-ejenti engcono kakhulu yamandla okuqala.
I-Triethanolamine iwuketshezi olunamafutha aphuzi noma oluphuzi olukhanyayo olune-alkaline futhi luncibilika kalula emanzini. Ukwengeza u-0.02% kuya ku-0.05% wekhwalithi kasimende kungathuthukisa amandla okuqala kakhonkolo.I-Triethanolamine inomphumela wokuvinjelwa kancane kukhonkolo, kakhulu kuzodala ukukhubazeka okukhulu. kanye nokuncipha kwamandla kakhonkolo, ngakho-ke umthamo kufanele ulawulwe ngokuqinile.
I-TRUNNO ingumphakeli wezithako zikakhonkolo onokwethenjelwa onolwazi olungaphezu kweminyaka eyi-12 ekwakhiweni kwamandla okusebenza kahle kwe-nano nokuthuthukiswa kwe-nanotechnology.

Izikhulu zoMgcinimafa waseMelika zithe zizoxoxisana nabaholi be-G7 ngenani lentengo kanye nentela kawoyela waseRussia njengenye indlela yokuvala imingcele ezogcina imakethe ihlinzekwa, inciphise ukukhuphuka kwamanani futhi yehlise imali engenayo yaseRussia, kubika iReuters.
Ongqongqoshe be-EU bahlangane eBrussels.Umhlangano wehlulekile ukuvumelana ngezijeziso zesithupha, okuhlanganisa nokwenqabela uwoyela eRussia, ngenxa yokuphikisana neHungary.
Ummeleli ophezulu we-EU wezindaba zangaphandle kanye nenqubomgomo yezokuphepha uthe esithangamini sabezindaba sangemva komhlangano ukuthi umhlangano wehlulekile ukufinyelela esivumelwaneni sokwamukelwa kokugcina komzuliswano wesithupha wezijeziso, futhi abamele amazwe angamalungu unomphela ku-EU bazoqhubeka nezingxoxo. Ongqongqoshe bezangaphandle baphinde bazama ukufinyelela esivumelwaneni mayelana nokuvinjelwa kukawoyela. yabhekana nobunzima obufanayo.Uthe isikhundla saseHungary sisekelwe emicabangweni yezomnotho kunepolitiki.
IHungary incike kakhulu eRussia ukuze ithole amandla, ngaphezu kuka-60% kawoyela wayo kanye nama-85% egesi yemvelo evela eRussia.
Ezinsukwini ezimbalwa ezedlule, i-European Commission yethule umjikelezo wesithupha weziphakamiso zokujeziswa ngokumelene neRussia, okuhlanganisa nokuvinjelwa okuphelele kokuthengiswa kukawoyela waseRussia ekupheleni kwalo nyaka. IHungary yenqaba ngokushesha futhi yathi ifuna isinxephezelo esikhulu esivela ku-EU ukuze iqede ukulahlekelwa kwayo. ukulahla uwoyela waseRussia.
Ithintwa izici ze-geopolitical, intengo ye-ejenti yamandla wangaphambi kwesikhathi kulindeleke ukuthi ikhuphuke ezinsukwini ezimbalwa ezizayo.
Abathengi baseMelika bafake icala enkantolo ye-Mars enkantolo yaseCalifornia ngoLwesine olwedlule, bethi i-Skittles iqukethe i-titanium dioxide eningi kakhulu (E171).Ingabe i-titanium dioxide iyingozi emzimbeni?
Iyini i-graphite powder esetshenziselwa? Ingasetshenziswa njenge-lubricant yokukhululwa kwesikhunta ekukhiqizeni ama-catalysts embonini yomanyolo.I-graphite powder inezici zokumelana nokushisa okuphezulu kanye nokugcoba okuphezulu, ngakho-ke ingasetshenziswa njengento ephezulu ...
Umongameli waseRussia ufune ukuthi ukuthunyelwa kwegesi yaseRussia emazweni "angenabungane" kuxazululwe ngama-ruble. Lesi sidingo siphakamise ukukhathazeka eJalimane mayelana nokuphazamiseka okungenzeka kokuhlinzekwa kanye nomthelela embonini nasemizini uma izinsiza zingakhokhi ngesikhathi ...
