Kev txhais ntawm cov dej ntub uas ntub
Tej yam ntub uas ntub dej yog qee zaum raug xa mus rau cov dej tshuaj tiv thaiv.
Kev txhais kom meej: Dej, dej nyab, thiab cov dej muaj dej txaus tuaj yeem ua rau muaj zog, tso cov roj av thiab ntau ntau cov cua kub, ua kom tawg, tawg, los yog tsim muaj cov khoom tawg, ua rau muaj kev phom sij.
Cov tshuaj ntub dab tsi yog dab tsi? Yuav ua li cas cais?
Xws li: Na, K, CaCumum carbide, Ca3P2 (calcium phosphide), CaO (txiv qaub), NaNH2 (sodium amide), LiAlH4 (lithium txhuas hydride), HCl3Si (trichlorosilane), NaBH4 (sodium borohydride) Tos.
kev faib tawm:
1, thawj theem ntawm cov nplaim dej
Cov tshuaj tiv thaiv nrog dej yog tsiv thiab nws yog ib qho yooj yim uas ua rau mob tawg lossis tawg, uas yog qhov txaus ntshai heev.
2, theem ob ntawm dej kub kub
Thaum nws nyob nrog dej los yog kua qaub, cov tshuaj tiv thaiv ceev kuj zoo tib yam thiab ua rau kub nyhiab los yog tawg, tiam sis nws tsis ua rau yus tawg lossis mob tawg.
3. Lwm yam dej kub
Sodium peroxide, potassium peroxide, sodium hydroxide, potassium hydroxide, fuming sulfuric acid, chlorosulfonic acid, phosphorus trichloride, titanium tetrachloride, tin tachachloride, anhydrous aluminium trichloride, quicklime, etc. Thaum reacted dej, muaj ntau cov cua sov tso tawm ze cov organic teeb meem thiab combustibles mus hlawv thiab taws.
Lus Cim: Tsis yog tas rau cov qauv saum toj no!
Ua kua dej nyob hauv Nyiv lub zog hluav taws xob
Monjyu yog lub Nyij Pooj thawj lub zog ua kom muaj zog thaum muaj nuclear reactor, uas yog siv puv nplai kom muaj kev lag luam loj. Nyob rau hauv 1995, ib qho kev sib tsoo loj ntawm cov kua sodium tov hluav taws tau tshwm sim.
Ceebtoom: Siv tshuab ua haujlwm loj hlob sai siv cov cua daj cua dub li ib lub roj cua. Radon yog ib hom tshuaj yeeb yaj kiab uas tsis muaj nyob rau hauv qhov xwm txheej thiab yog lom thiab carcinogenic. Nws yuav ua kom muaj zog loj thaum nws muab faib, vim li ntawd nws yog tsim rau kev tsim foob pob.
Ordinary nuclear fais fab nroj tsuag muaj dej ntshiab li cua txias, tiam sis lub tshuab hluav taws kub high-speed yuav tsum siv cov dej phom sij heev thaum ua kom txias txias. Wenshu cov cua sov nres rau 15 xyoo tom qab kev sib tsoo.
Ceev faj kom txuag cov dej ntub uas ntub
1 Ntsev sodium potassium yuav tsum muab tso rau hauv cov pa quenching los yog roj ntsha kom muab khi thiab khaws cia
Yam khoom uas muaj xws li sodium lossis potassium hlau reacts nrog dej, uas tso cov roj av hydrogen thiab ua kom tawg lossis tawg. Yog li, cov tshuaj sodium thiab potassium ntawm cov hlau yuav tsum muab txiav rau hauv cov hnab me me thiab muab tso rau hauv cov txia ua kua los yog roj ntsha kom tau muab sib khi thiab khaws cia.
Thaum dissolving sodium hlau, nws yuav muab tso rau hauv ethanol kom hnov mob, tab sis kev saib xyuas yuav tsum tau noj kom tiv thaiv tau cov kab mob hydrogen uas txais hluav taws.
Thaum cov hlau potassium yog decomposed, tib lub lag luam yog nqa tawm nyob rau hauv kev tiv thaiv ntawm nitrogen.
Ntawm cov ntawv tshwj xeeb yog tias nws cov khib nyiab kuj tseem khaws cia rau hauv cov pa quenching los yog kerosene.
Piv txwv li, seem ntawm cov hlau sodium thiab potassium tsis txauv rov qab rau lub sijhawm vim tus neeg teb xov tooj tsis hnov lus zoo, thiab cuam tshuam nrog dej los yog ya raws kom ua kom tawg taus.
SYSBEL "Tshuaj Muaj Kev Nyab Xeeb Tshuaj" yog siv los tsim ua lag luam, kev tsim khoom, cov chaw ua haujlwm hauv tsev kawm ntawv, zaub mov kev lag luam, kev lag luam tsim tsheb, tshiab lub zog thiab lwm yam kev lag luam los tiv thaiv txoj kev lag luam.
2 Xyuam xim rau qhov txaus ntshai ntawm calcium carbide reacting nrog dej
Calcium carbide reacts nrog dej los tsim acetylene, uas ua rau hluav taws kub thiab tawg.
Piv txwv, thaum acetylene roj raug ua nyob rau hauv kev kuaj, cov roj acetylene uas tau sau hauv cov fwj tshuaj sau los yog qhov qub txav thiab feem ntau tawg.
3 xyuam xim rau qhov txaus ntshai ntawm sodium potassium thiab halide cov tshuaj tiv thaiv
Cov xuab zeb xws li sodium lossis potassium react nrog halides thiab tawg tau.
4 Nco ntsoov qhov txaus ntshai ntawm cov tshuaj calcium phosphide reacting nrog dej
Calcium phosphide reacts nrog dej tso tawm phosphine (PH3 yog ib co roj muaj kuab), uas yog nrog rau kev tso tawm ntawm pyrophoric P2H4, uas ua rau kom tawg lossis tawg.
5 them sai sai rau qhov pov tseg ntawm cov hlau hydride
Qhov kev txiav txim ntawm cov hlau hydride nrog dej (lossis dej vapor) kuj kub nyhiab. Yog tias nws muab pov tseg, nws tuaj yeem raug txhaj tshuaj rau hauv ethyl acetate hauv feem me me (qhov kev ua haujlwm tsis zoo yog tsis tau).
6 Ua tib zoo saib kom txaus ntshai ntawm exothermic cov tshuaj tiv thaiv nruab nrab ntawm quicklime thiab dej
Quicklime (calcium oxide) ua nrog 1/3 ntawm qhov hnyav ntawm dej, txawm tias nws tsis tuaj yeem ntes hluav taws, tab sis ua kom kub ntau dua kom sov siab txog 150-300 ° C los yog siab dua, txaus ua rau ntoo phom los yog them tarpaulin ntes hluav taws, los yog Lwm yam khoom kub hnyiab nyob ib ncig ntawm qhov hluav taws kub.
7 Hnav cov hnab looj tes thiab lub taub hau thaum ua haujlwm
Thaum siv cov yeeb-tshuaj zoo li cov pa hluav taws, hnav cov hnab looj tes tiv thaiv los yog siv cov caws pliav. Nws tsis yog nquahu kom coj ncaj qha ntawm tes, tshwj xeeb tshaj plaws ntub tes.
Cov tshuaj yaj yeeb yog corrosive rau ntawm daim tawv nqaij.
8 Kuv yuav ua li cas yog tias cov khoom uas siv hauv qhov dej tuaj yeem hluav taws?
Thaum hluav taws kub yog tshwm sim los ntawm cov dej muaj kuab, nws muaj peev xwm raug cawm nrog dej qab zib, qhuav xuab zeb, qhuav hmoov ntawm sodium carbonate, hmoov qhuav ntawm calcium carbonate, graphite hmoov, vermiculite hmoov, qhuav av, ntsev lossis dej qab zib tshauv.
Txhob siv cov dej, dej noo, ua npuas dej, cov roj carbon dioxide tua hluav taws lossis cov roj carbon dioxide hydrocarbon.
9 Dab tsi koj yuav tsum xyuam xim thaum khaws cov khoom ntaum nyob hauv dej?
Ceev faj:
1 Khaws rau hauv qhov chaw qhuav, xyuam xim rau cov dej tsis qab thiab dej noo;
Nws yog cai txwv tsis pub teeb tsa dej nyob hauv 2 chav;
3 nrog cov kua qaub, oxidant, halogen, thiab lwm yam. Muab faib ua kev cia thiab tsheb thauj mus los;
4 Tsis txhob khaws cov khoom ntim cia;
5 los mus tiv thaiv kev cuam tshuam, kev co, kev sib txhuam;
6 Kev haus luam yeeb raug txwv tsis pub, thiab tsis muaj qhov txwv kub thiab cov chaw tua hluav taws;
7 Rau cov huab cua kub hnyiab, tshwj xeeb yuav tsum them rau cov hmoov av tawg.
Feem ntau cov kev txuag cov xim ntses txoj hnyav
Nws yog feem ntau nyob rau hauv cov pa quenching, cov ntxhia roj thiab cov roj benzene uas muab cia rau hauv ib daim ntawv foos.
Ntsev sodium uas muaj purity requirements tsis tuaj yeem muab cia rau hauv kerosene vim ntsev cov tshuaj hawb nrog cov organic acids xws li kerosene los tsim ib yam khoom xws li sodium silicate (daj) txuas nrog rau ntawm sodium.
Cov xim ntses uas muaj hlau nplua nuj muaj peev xwm tsis muab khaws cia rau hauv cov pa roj carbon paraffin vim hais tias cov pa oxygen nkag mus rau hauv cov pa roj paraffin, ua rau cov nplaim ntawm cov xim ntses hlau ua rau grey thiab tsim ib cov yeeb yam oxide.
Nws tuaj yeem muab khaws cia rau hauv ib qho me me ntawm sodium nrog cov uas tsis muaj kev purity, soaked hauv kerosene los yog muab tso rau hauv cov pa tawm paraffin. Raws li ib txwm muaj, preservation ntawm sodium nyob hauv kev kuaj kev kuaj, cov purity tsis siab.
Tus nqi loj feem ntau yog muab cia rau hauv cov hlau nruas thiab khi nrog cov pa roj carbon.
SYSBEL Biohazard pov tseg tau
10 dej tuaj yeem tshwm sim los ntawm acid los yog oxidant, qhov kev pheej hmoo siab ntau dua
Ntxiv nrog rau cov tshuaj tiv thaiv dej, cov kab mob ntub dej yuav tuaj yeem nrog cov kua qaub lossis oxidant, thiab hnov ntau dua li dej, thiab qhov kev nyab xeeb ntau dua.
Yog li, kev cia khoom thiab kev siv yuav tsum tsis txhob siv cov acids, oxidants, chlorine, oxygen, nitrous oxide, bromine, iodine, sulfur, phosphorus, cov khoom muaj dej, hnyav hlau ntsev, lwm yam khoom phom sij, thiab kev tua hluav taws. Cia.
