Calcium Carbide Cov Qib Zoo, Cov Qauv Tsis Txaus Siab thiab Cov Ntawv Qhia Txog Kev Lag Luam Thoob Ntiaj Teb

Calcium carbide muaj nyob rau hauv ntau qib zoo, txhua tus txhais los ntawm qib purity, impurity cov ntsiab lus, thiab cov yam ntxwv ua haujlwm. Rau cov neeg xa khoom thoob ntiaj teb uas koom nrog kev lag luam tshuaj xa tawm, nkag siab cov qib no, cov qauv tsis huv, thiab cov txheej txheem xa tawm yog qhov tseem ceeb rau kev xaiv cov khoom tsim nyog rau cov ntawv thov tshwj xeeb, ua kom ntseeg tau raws li kev cai thoob ntiaj teb, thiab zam kev pheej hmoo ntawm kev yuav khoom.

 

Cov qib tseem ceeb ntawm calcium carbide yog qib kev lag luam, qib siab -purity qib, thiab qis- qib. Muaj qib calcium carbide, qib kev lag luam feem ntau, muaj purity ntau ntawm 96-98% thiab tsim nyog rau kev siv dav dav xws li acetylene tiam, hlau vuam, thiab steel desulfurization. High- purity qib calcium carbide (Ntau dua lossis sib npaug li 99%) yog siv rau hauv siab -kawg cov organic synthesis thiab tshuaj intermediates, qhov twg txawm cov kab impurities tuaj yeem cuam tshuam cov khoom zoo. Tsawg-qib calcium carbide (tsawg dua lossis sib npaug li 95%) feem ntau yog siv hauv kev tsim cov chiv thiab lwm yam tsawg- thov kev thov.

 

Kev tswj hwm impurity yog qhov tseem ceeb hauv calcium carbide zoo. Cov impurities feem ntau suav nrog silicon carbide, hlau carbide, calcium oxide, thiab sulfur. Silicon carbide ntau dhau yuav txo cov acetylene tawm los thiab ua rau kom muaj zog noj, thaum cov ntsiab lus sulfur siab tuaj yeem ua rau acetylene thiab ua rau cov khoom siv corrosion. Cov txheej txheem thoob ntiaj teb, xws li ISO 5959 thiab Suav GB / T 10665, qhia cov kev txwv tsis pub muaj kev txwv nruj: sulfur Tsawg dua lossis sib npaug li 0.06%, phosphorus Tsawg dua lossis sib npaug li 0.02%, thiab silicon carbide Tsawg dua lossis sib npaug li 2.0% rau qib qib calcium carbide.

 

Rau kev xa tawm ntau thoob ntiaj teb, calcium carbide yuav tsum ua raws li kev cai thauj khoom thoob ntiaj teb thiab cov ntaub ntawv. Nws raug cais raws li cov khoom siv phom sij (UN 1402, Chav Kawm 4.3) vim nws cov tshuaj tiv thaiv hnyav nrog dej, yog li nws yuav tsum tau ntim rau hauv cov ntim ntim, noo noo- cov ntaub ntawv pov thawj (xws li cov nruas hlau lossis cov hnab ntim ntau) kom tiv thaiv kev sib cuag nrog dej. Cov ntaub ntawv xa tawm suav nrog Daim Ntawv Tshaj Tawm Txog Cov Khoom Txaus Ntshai (DGD), Cov Ntaub Ntawv Kev Nyab Xeeb Cov Ntaub Ntawv (MSDS), Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (CoA), thiab daim ntawv xa nyiaj ua lag luam.

 

Cov neeg tuaj yeem yuav tsum xav txog cov kev cai ntshuam ntawm lawv lub tebchaws. Lub EU xav kom REACH rau npe rau calcium carbide, thaum lub tebchaws United States tso cai ua raws li OSHA cov qauv rau cov ntaub ntawv txaus ntshai. Tsis tas li ntawd, cov neeg yuav khoom yuav tsum txheeb xyuas tus neeg muag khoom kev tsim khoom, kev tswj xyuas qhov zoo, thiab kev xa tawm kom ntseeg tau ruaj khov batch sib xws thiab xa khoom raws sijhawm.

 

Los ntawm kev nkag siab cov qib zoo, cov qauv impurity, thiab cov txheej txheem xa tawm ntawmcalcium carbide, cov neeg tuaj yeem thoob ntiaj teb tuaj yeem txiav txim siab txog kev yuav khoom, xaiv cov khoom tsim nyog rau lawv daim ntawv thov, thiab ua raws li cov kev cai thoob ntiaj teb, txo cov kev pheej hmoo thiab tsim kom ntev ntev - kev koom tes nrog cov neeg siv khoom.
