Nrov Kev Tshawb Fawb Txog Tshuaj Tiv Thaiv Kab Mob: Sodium Cyanide

1. Taw qhia txog Sodium Cyanide

Cubic crystal system, dawb crystalline hais los yog hmoov, yooj yim rau deliquesce, nrog ib tug tsis hnov ​​tsw ntawm iab almonds. Cov tshuaj lom heev, kev sib cuag ntawm daim tawv nqaij qhov txhab, nqus pa, thiab noj cov kab mob tuaj yeem ua rau lom thiab tuag taus. Cov tshuaj formula yog NaCN, melting point 563.7 ℃, boiling point 1496 ℃. Yooj yim soluble hauv dej, yooj yim hydrolyzed los ua hydrogen cyanide, aqueous tov muaj zog alkaline, ib qho tseem ceeb ntawm cov tshuaj raw khoom, siv nyob rau hauv yooj yim tshuaj synthesis, electroplating, metallurgy thiab organic synthesis tshuaj, tshuaj tua kab thiab hlau kho. Complexing agent, masking agent.

2. Lub cev muaj zog

Nws yog lub cubic crystal system, dawb crystalline granules los yog hmoov, yooj yim deliquescent, nrog ib tug iab iab iab almond tsw. Nws yog soluble hauv dej, ammonia, ethanol thiab methanol.

3. Kev ua haujlwm tseem ceeb

Kaw kom nruj, muab cov pa hauv zos txaus thiab qhov cua dav dav. Mechanize thiab automate lub lag luam kom ntau li ntau tau. Cov neeg ua haujlwm yuav tsum tau kawm tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug nquahu kom cov neeg ua haujlwm hnav hood-hom hluav taws xob cua lim cov plua plav ua pa, ib qho roj hmab los tiv thaiv cov khaub ncaws, thiab hnab looj tes roj hmab. Tsis txhob tsim cov hmoov av. Tsis txhob sib cuag nrog oxidants thiab acids. Load thiab unload maj mam thaum lub sij hawm thauj mus los los tiv thaiv kev puas tsuaj rau lub ntim thiab ntim. Nruab nrog cov khoom siv kho mob thaum muaj xwm ceev. Cov thawv khoob yuav muaj cov khoom tsis zoo.

4. Kev Nyab Xeeb Kev Nyab Xeeb

Inhibits ua pa enzymes, ua rau intracellular asphyxiation. Kev nqus pa, kev tswj qhov ncauj lossis kev nqus percutaneous tuaj yeem ua rau mob hnyav. Kev tswj qhov ncauj ntawm 50-100 mg tuaj yeem ua rau tuag sai. Kev tuag tsis yog tam sim no tau muab faib ua 4 theem: theem prodromal muaj mucosal irritation, ua pa nrawm thiab tob tob, qaug zog, thiab mob taub hau; Kev tswj qhov ncauj muaj loog ntawm lub ntsis ntawm tus nplaig thiab qhov ncauj, thiab lwm yam. Cov theem dyspnea muaj dyspnea, nce ntshav siab, thiab ci liab ntawm daim tawv nqaij thiab mucous daim nyias nyias. Convulsion theem muaj convulsions, coma, thiab ua pa tsis ua hauj lwm. Kev tuag tes tuag taw muaj tag nrho lub cev cov leeg so, ua pa thiab lub plawv dhia nres, thiab tuag. Lub sij hawm ntev raug rau me me ntawm cyanide tuaj yeem ua rau neurasthenia syndrome, qhov muag thiab ua pa sab sauv. Yuav ua rau pob khaus.

5. Teb ceev ceev

Cais tawm qhov chaw paug paug thiab txwv kev nkag mus. Nws raug pom zoo tias cov neeg ua haujlwm thaum muaj xwm txheej ceev yuav hnav lub ntsej muag plua plav (lub ntsej muag puv ntsej muag) thiab tiv thaiv roj. Tsis txhob tuaj rau hauv kev sib cuag ncaj qha nrog cov khoom xau.

Kev xau me me: Tsis txhob tsim cov plua plav thiab sau cov xau hauv lub thawv qhuav, huv si nrog lub duav huv.

Kev xau loj loj: Npog nrog cov ntawv yas lossis canvas, thiab tom qab ntawd sau rau kev rov ua dua lossis thauj mus rau qhov chaw pov tseg pov tseg.

6. Kev pab thawj zaug

Kev sib cuag ntawm daim tawv nqaij: Tshem tawm cov khaub ncaws tsis huv tam sim ntawd thiab yaug kom huv si nrog dej ntws los yog 5% sodium thiosulfate tov rau tsawg kawg 20 feeb. Nrhiav kev kho mob.

Kev sib cuag qhov muag: Tam sim ntawd rub daim tawv muag thiab yaug kom huv si nrog dej txaus los yog ntsev kom tsawg li 15 feeb. Nrhiav kev kho mob.

Inhalation: Tawm ntawm qhov chaw sai sai rau huab cua ntshiab. Khaws qhov cua qhib. Yog ua pa nyuaj, muab cov pa oxygen. Yog tias ua pa thiab lub plawv dhia nres, tam sim ntawd ua pa ua pa (tsis txhob siv lub qhov ncauj-rau-qhov ncauj) thiab sab hauv siab compression. Muab amyl nitrite nqus tau pa thiab nrhiav kev kho mob.

Noj: Haus dej sov kom ntau thiab ua kom ntuav. Ntxuav lub plab nrog 1: 5000 poov tshuaj permanganate lossis 5% sodium thiosulfate tov. Nrhiav kev kho mob.

7. Kev ntsuas hluav taws kub

Txoj kev tua hluav taws: Cov khoom no tsis yooj yim hlawv. Yog tias muaj hluav taws, sim cawm cov khoom kom tiv thaiv cov ntim khoom kom tsis txhob puas thiab ua rau muaj kuab paug rau ib puag ncig. Cov neeg tua hluav taws yuav tsum hnav lub ntsej muag roj thiab cov khaub ncaws tua hluav taws puv lub cev thiab tua hluav taws rau sab cua. Cov tshuaj tua hluav taws: hmoov qhuav, xuab zeb thiab av. Txwv tsis pub siv carbon cov tshuaj tua hluav taws dioxide thiab acid-base los tua hluav taws.

8. Kev khaws cia tseem ceeb

Khaws rau hauv qhov chaw txias, qhuav, zoo-ventilated warehouse. Khaws kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Tus txheeb ze av noo nyob rau hauv lub warehouse yuav tsum tsis txhob ntau tshaj 80%. Lub pob yuav tsum raug kaw. Nws yuav tsum tau muab cais los ntawm oxidants, acids, thiab edible tshuaj, thiab yuav tsum tsis txhob tov. Lub chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog kom muaj cov xau. Kev tswj hwm "tsib khub" rau cov tshuaj lom neeg muaj zog heev yuav tsum tau ua nruj me ntsis.

9. Cov ntaub ntawv kev thauj mus los

Cov txheej txheem ntim khoom: Muab tso rau hauv hnab yas, kaw lub hnab lub qhov ncauj, thiab tom qab ntawd muab tso rau hauv ib lub thawv steel nrog lub thickness tsis pub tsawg tshaj 0.75 hli. Lub hau npog yog nruj nreem clamped. Qhov hnyav ntawm txhua lub thoob yog 50 kg; threaded iav fwj, hlau-capped iav fwj, yas hwj los yog hlau

Cov saum toj no yog qee yam kev paub txog Sodium cyanide. Thov nyeem kom zoo yog tias koj xav tau.
