    CHEMICAL PROPERTIES

    Calcium carbide (molecule formula: CaC2), yog ib hom tshuaj tseem ceeb raw cov ntaub ntawv uas tsim los ntawm cov tshuaj ua cov limestone. Xyoo 1892, H. Maysan (Fabkis) thiab H. Wilson (United States) ib txhij tsim ib txoj hauv kev tsim cov calcium carbide raws li lub cub tawg txo. Tebchaws Asmeskas tau ua tiav kev lag luam hauv xyoo 1895. Cov cuab yeej ntawm calcium carbide muaj feem xyuam rau nws cov purity. Nws cov khoom lag luam feem ntau yog kev sib xyaw ntawm calcium carbide thiab calcium oxide, thiab tseem muaj cov kab ntawm sulfur, phosphorus, nitrogen thiab lwm yam impurities. Nrog rau cov ntsiab lus ntawm impurities, nws xim nthuav tawm grey, xim av rau dub. Lub melting point thiab hluav taws xob conductivity ob qho tib si txo nrog txo qhov purity. Lub purity ntawm nws cov khoom lag luam feem ntau yog 80% nrog mp yog 1800 ~ 2000 ° C. Nyob rau hauv chav tsev kub, nws tsis hnov ​​​​mob nrog huab cua, tab sis nws muaj peev xwm muaj oxidation cov tshuaj tiv thaiv saum toj 350 ℃, thiab muaj cov tshuaj tiv thaiv nrog nitrogen ntawm 600 ~ 700 ℃ los tsim calcium cyanamide. Calcium carbide, thaum hla dej los yog chav, tsim acetylene thiab tso cua sov ntau. CaC2 + 2H2O─ → C2H2 + Ca (OH) 2 + 125185.32J, 1kg ntawm ntshiab calcium carbide tuaj yeem tsim tau 366 L ntawm acetylene 366l (15 ℃, 0.1MPa). Yog li ntawd, rau nws cia: calcium carbide yuav tsum nruj me ntsis kom deb ntawm dej. Nws feem ntau tau ntim rau hauv lub thawv hlau kaw, thiab qee zaum muab cia rau hauv lub tsev qiv ntawv qhuav tau ntim nrog nitrogen yog tias tsim nyog.

    APPLICATION AREA

    Pharmaceutical
    Kev lag luam roj
    Tshuaj tua kab
    Diesel Cav Roj
    Cov tub yees
    Aerosol tshuaj tsuag

    Calcium carbide (CaC2) muaj cov ntxhiab tsw zoo li qej thiab reacts nrog dej los tsim cov roj acetylene ntxiv rau calcium hydroxide thiab cua sov. Yav dhau los, nws tau siv nyob rau hauv miners 'lamp mus txuas ntxiv tsim ib tug me me acetylene nplaim los muab ib co illumination nyob rau hauv thee mines.

    Calcium carbide yog siv los ua desulfurizer, lub cev qhuav dej ntawm cov hlau, roj hauv cov hlau ua, muaj zog deoxidizer thiab ua cov roj acetylene. Nws yog siv los ua cov khoom pib rau kev npaj calcium cyanamide, ethylene, chloroprene roj hmab, acetic acid, dicyandiamide thiab cyanide acetate. Nws yog siv nyob rau hauv carbide teeb, cov khoom ua si cannons xws li big-bang cannon thiab xyoob cannon. Nws yog txuam nrog calcium phosphide thiab siv nyob rau hauv floating, self-igniting naval signalCalcium carbide yog qhov tseem ceeb tshaj plaws carbide industrially vim nws lub luag hauj lwm tseem ceeb raws li lub hauv paus ntawm acetylene kev lag luam. Hauv cov chaw uas tsis muaj roj av, Calcium Carbideyog siv los ua cov khoom pib rau kev tsim cov acetylene (1 kg ntawm carbide yields ~ 300 litres acetylene), uas, nyob rau hauv lem, yuav siv tau los ua ib lub tsev thaiv rau ntau yam ntawm cov organic tshuaj (xws li yas acetate, acetaldehyde thiab acetic acid. ). Hauv qee qhov chaw, acetylene kuj tseem siv los tsim cov yas chloride, cov khoom siv raw rau kev tsim cov PVC.
    Ib qho tseem ceeb tsawg siv Calcium Carbide muaj feem xyuam rau kev lag luam ferilizers. Nws reacts nrog nitrogen los tsim calcium cyanamide, uas yog cov khoom pib rau zus tau tej cov cyanamide (CH2N2). Cyanamide yog ib yam khoom siv ua liaj ua teb siv los txhawb cov foliation thaum ntxov.
    Calcium Carbide kuj tseem tuaj yeem ua haujlwm ua tus neeg sawv cev desulfurizing los tsim cov pa roj carbon tsawg. Tsis tas li ntawd, nws yog siv los ua tus neeg sawv cev txo qis los tsim cov hlau los ntawm lawv cov ntsev, piv txwv li, rau kev txo qis ntawm tooj liab sulfide rau hlau tooj liab. nplaim taws. Tsis tas li ntawd, nws yog koom nrog hauv kev txo cov tooj liab sulfide rau hlau tooj liab.

    YUAV UA LI CAS LOS NTAWM US

    Chemwin tuaj yeem muab ntau hom hydrocarbons thiab cov kuab tshuaj tshuaj lom neeg rau cov neeg siv khoom.Ua ntej ntawd, thov nyeem cov lus qhia hauv qab no txog kev ua lag luam nrog peb: 

    1. Kev ruaj ntseg

    Kev nyab xeeb yog peb qhov tseem ceeb tshaj plaws. Ntxiv nrog rau kev muab cov neeg siv khoom paub txog kev nyab xeeb thiab ib puag ncig tus phooj ywg siv peb cov khoom, peb kuj tau cog lus los xyuas kom meej tias kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg cog lus raug txo qis rau qhov tsim nyog thiab ua tau yam tsawg kawg nkaus. Yog li, peb xav kom tus neeg siv khoom kom ntseeg tau tias qhov tsim nyog tshem tawm thiab khaws cov qauv kev nyab xeeb tau ua tiav ua ntej peb xa khoom (thov xa mus rau HSSE appendix nyob rau hauv cov nqe lus dav dav thiab kev muag khoom hauv qab no). Peb cov kws tshaj lij HSSE tuaj yeem muab kev taw qhia txog cov qauv no.
