Calcium Carbide (CaC₂) yog dab tsi thiab Yuav Yuav Li Cas?

Calcium carbide (cov tshuaj formula:CaC₂) yog ib qho inorganic compound tsim los ntawm calcium thiab carbon, paub txog nws lub peev xwm tshwj xeeb los teb cov dej los tsimacetylene roj​ (C₂H₂)-cov roj ntau yam thiab tshuaj lom neeg ua ntej. Ua ntej sib xyaw ua ke hauv xyoo 1892 los ntawm Fab Kis tus kws chemist Henri Moissan siv lub tshuab hluav taws xob arc, calcium carbide tau dhau los ua lub hauv paus ntawm kev lag luam thiab kev ua liaj ua teb thoob ntiaj teb.

 

Ntu 1:Calcium Carbide (CaC₂) yog dab tsi?​

1. Cov khoom siv tshuaj​

Molecular StructureIonic crystal lattice nrog Ca²⁺ ions thiab C₂²⁻ (acetylide) ions.

Lub cev lub xeev: Greyish-dub khoom (khoom / granules) nrog qhov ceev ntawm ~ 2.22 g / cm³.

Melting Point: 2300℃(sublimes ntawm qhov kub thiab txias).

Reactivity: Siab reactive nrog dej, cawv, thiab acids. Reacts hnyav nrog dej kom tso tawm acetylene:

CaC2​+2H2​O →C2​H2​↑+Ca(OH)2​

2. Cov ntawv thov tseem ceeb​

Calcium carbide's utility stems los ntawm nws cov acetylene -tsim muaj peev xwm thiab lub luag hauj lwm nyob rau hauv tshuaj synthesis:

Kev tsim cov Acetylene: Siv nyob rau hauv oxy-acetylene vuam/txiav (nplaim kub ~ 3300℃).

Ua liaj ua teb: Ripens txiv hmab txiv ntoo (txiv tsawb, txiv nkhaus taw) los ntawm kev ua rau ethylene -zoo li cov teebmeem.

metallurgy: Deoxidizes thiab desulfurizes hlau hauv foundries.

Tshuaj: Precursor rau PVC, hluavtaws roj hmab, acetic acid, thiab yas.

3. Qib ntawm Calcium Carbide​

Calcium carbide yog categorized los ntawmkev huv(CaC₂ cov ntsiab lus) raws li nws siv:

Qib Industrial80-90% CaC₂ (rau vuam, steelmaking).

High-Purity Qib: Ntau dua lossis sib npaug li 95% CaC₂ (khoom noj / kev ua liaj ua teb, tshuaj).

 

Ntu 2:Yuav Ua Li Cas Calcium Carbide kom nyab xeeb thiab ua tau zoo​

Kev yuav cov calcium carbide yuav tsum tau ua tib zoo xav txog kev purity, kev ntseeg ntawm tus neeg muag khoom, thiab kev ua raws li kev nyab xeeb. Ua raws li cov kauj ruam no kom ntseeg tau tias kev yuav khoom tiav:

Kauj Ruam 1: Qhia koj cov kev xav tau​

Qhia meej koj cov kev xav tau kom txo qis cov kev xaiv:

Purity: Sib piv qib rau daim ntawv thov (xws li, 98% CaC₂ rau txiv hmab txiv ntoo ripening).

Daim ntawv: Lumps (10–50 mm), granules, los yog hmoov (hmoov ntau reactive tab sis nyuaj rau khaws).

Ntau: Bulk (tons) rau kev lag luam siv lossis cov khoom me me rau kev sim.

Cov ntawv pov thawj: Xyuas kom ua raws li cov qauv zoo li ISO 9001, REACH, lossis FDA (rau kev siv zaub mov).

Kauj Ruam 2: Tshawb nrhiav cov neeg muab khoom muaj npe nrov​

Xaiv cov chaw muag khoom nrog cov ntaub ntawv pov thawj. Nrhiav:

Kev Paub Txog Kev Lag Luam: Cov neeg muab khoom nrog 5+ xyoo hauv calcium carbide ntau lawm.

Kev Tswj Xyuas Zoo: Thib peb-cov ntaub ntawv qhia chaw kuaj mob (CoA) txheeb xyuas qhov purity, noo noo, thiab impurity theem (xws li, arsenic<10 ppm).

Ntiaj teb no ncav cuag: Cov neeg muab khoom nrog lub peev xwm logistics thoob ntiaj teb (xws li, daim ntawv tso cai xa tawm, kev tshaj lij kev lis kev cai).

Kauj Ruam 3: Ntsuas cov khoom Specifications​

Thov ibCertificate of Analysis (CoA)rau txhua batch. Cov ntsiab lus tseem ceeb los xyuas:

CaC₂ Cov ntsiab lus: Yuav tsum ua kom tau raws li qhov koj xav tau qib (piv txwv li, Ntau dua lossis sib npaug li 98%).

Cov impurities: Tsawg arsenic (As<10 ppm), phosphorus (P <20 ppm), and sulfur (S <0.1%).

Moisture: <0.5% (to prevent premature acetylene release during storage).

Kauj Ruam 4: Muab qhov tseem ceeb ntawm kev nyab xeeb thiab kev ua raws cai​

Calcium carbide yog qhov txaus ntshai- xyuas kom cov neeg muab khoom ua raws li kev cai nyab xeeb:

Ntim: Cua- nruj, noo noo- cov thawv pov thawj (steel nruas, desiccant- cov hnab ntim khoom).

Kev sau npe: Cov lus ceeb toom meej meej txog kev ua haujlwm nrog dej thiab tuav kom raug.

Cov ntaub ntawv: MSDS (Material Safety Data Sheet) thiab daim ntawv tso cai thauj khoom (UN 1402, Chav Kawm 4.3).

Kauj Ruam 5: Sib piv Tus Nqi thiab Cov Cai​

Tus nqi Factors: Purity, kom muaj nuj nqis, thiab shipping nrug cuam tshuam tus nqi. High - qib purity raug nqi 20–50% ntau dua li qib kev lag luam.

Cov nqe lus them nqi: Sib tham cov ntawv qiv nyiaj (LC), them nyiaj ua ntej, lossis qhib cov ntsiab lus qhib.

Kev xa khoom: Opt rau ceev, kev pov hwm tus me nyuam kom tsis txhob muaj kev ncua lossis kev puas tsuaj.

Kauj Ruam 6: Muab koj daim ntawv xaj thiab txheeb xyuas qhov khoom xa tuaj​

Order Confirmation: Tau txais daim ntawv lees paub ntawm cov lus qhia tshwj xeeb, kom muaj nuj nqis, thiab lub sijhawm xa khoom.

Kev tshuaj xyuas: Thaum tuaj txog, tshuaj xyuas cov ntim rau kev puas tsuaj thiab tshawb xyuas CoA tiv thaiv koj cov cai.
