Calcium Carbide Ua li cas?

Calcium carbide (CaC₂)yog ib qho tseem ceeb ntawm kev lag luam chemical uas tsim los ntawm kev kub siab - cov tshuaj tiv thaiv kub ntawm txiv qaub (calcium oxide, CaO) thiab coke (carbon, C). Cov txheej txheem no, hu uacarbothermal txo, yuav tsum muaj cov cuab yeej tshwj xeeb thiab kev tswj xyuas meej kom ua tau zoo thiab kev nyab xeeb. Hauv qab no, peb rhuav tshem cov kauj ruam - los ntawm - cov txheej txheem tsim khoom, cov ntaub ntawv tseem ceeb, thiab kev xav txog kev lag luam.

 

1. Cov khoom siv raw​

Cov khoom xyaw tseem ceeb rau calcium carbide yog:

Txiv qaub (Calcium Oxide, CaO): Muab los ntawm limestone (CaCO₃) los ntawm calcination ( cua sov rau ~ 900℃kom tsav tawm CO₂).

Coke (Carbon, C): High -purity carbonaceous khoom (feem ntau anthracite los yog roj av coke) uas ua raws li tus neeg sawv cev txo.

Ob qho khoom siv yuav tsum qhuav thiab tsis muaj leej faj, phosphorus, thiab lwm yam impurities kom tsis txhob kis cov khoom kawg.

2. Cov txheej txheem Carbothermal txo​

Calcium carbideyog synthesized nyob rau hauv ibhluav taws xob arc rauv- lub nkoj loj, cylindrical lined nrog cov ntaub ntawv refractory (xws li, magnesium oxide) tiv taus cua sov. Cov txheej txheem muaj peb theem tseem ceeb:

Theem 1: Them rau qhov cub​

Txiv qaub thiab coke sib tov nyob rau hauv ib qho piv txwv ntawm molar (kwv yees li 1: 3 los ntawm qhov hnyav) thiab muab tso rau hauv lub qhov cub los ntawm lub hopper. Cov sib tov yog ua tib zoo qhuav kom tsis txhob ya raws los ntawm reacting ntxov ntxov nrog raw cov ntaub ntawv.

Theem 2: Cua sov thiab tshuaj tiv thaiv​

Lub cub hluav taws xob muaj zog nrog siab -voltage electrodes, tsim kom muaj hluav taws xob arc uas ua kom sov qhov sib tov rau2000-2500 degree-zoo tshaj qhov melting point ntawm calcium carbide (~447℃). Ntawm cov kub no, cov pa roj carbon hauv coke txo calcium oxide rau calcium carbide:

CaO+3C2000–2500℃CaC2​+CO↑

Los ntawm - khoom: Cov pa roj carbon monoxide (CO) raug tso tawm thaum lub sijhawm cov tshuaj tiv thaiv thiab feem ntau raug ntes thiab hlawv ua roj rau lub tshuab hluav taws xob lossis lwm yam haujlwm cog.

Kauj Ruam 3: Tapping thiab Txias​

Molten calcium carbide sau rau hauv qab ntawm lub cub tawg, qhov twg nws yog ncua sij hawm tapped rau hauv pwm los yog ladles. Cov kua carbide cools thiab solidifies mus rau greyish -dub pob los yog granules. Thaum txias, cov khoom raug crushed, tshuaj ntsuam, thiab txheeb raws li qhov loj me (xws li, 50-100 mm lumps for industrial use).

3. Cov txheej txheem tseem ceeb tswj​

Yuav kom ntseeg tau siab purity thiab tawm los, manufacturers saib:

Kub: Kev tuav 2000-2500℃yog qhov tseem ceeb- tsawg dhau, thiab cov tshuaj tiv thaiv tsis tiav; siab dhau lawm, thiab tus nqi zog skyrocket.

Raw Khoom Zoo: Cov impurities xws li sulfur los yog phosphorus nyob rau hauv coke / txiv qaub tuaj yeem paug cov carbide, txo nws cov kev siv tau (xws li, hauv zaub mov / kev ua liaj ua teb).

Gas Management: CO emissions raug tswj kom ua tau raws li ib puag ncig cov cai thiab txo qhov kev pheej hmoo ntawm kev nyab xeeb.

4. Muaj-Sale Production​

Cov nroj tsuag loj calcium carbide tsim ntau txhiab tons txhua xyoo. Cov cuab yeej siv niaj hnub siv cov tshuab automated rau:

Tswj cov khoom siv raw khoom noj thiab qhov cub kub.

Kev ntes thiab rov ua dua CO roj rau kev siv hluav taws xob.

Kov molten carbide kom ruaj ntseg los tiv thaiv kev nchuav los yog tawg.

5. Kev txiav txim siab txog kev nyab xeeb thiab ib puag ncig​

Kev phom sij: Cov txheej txheem cuam tshuam nrog huab cua kub, cov pa roj CO lom, thiab cov khoom siv molten reactive. Cov txheej txheem kev nyab xeeb nruj (piv txwv li, PPE, qhov cua) yog qhov yuav tsum tau ua.

Pov tseg: Siv cov ntaub ntawv refractory thiab plua plav rov qab los yog pov tseg raws li kev cai ib puag ncig.
