Cov pa roj carbon dioxide (CO2)

Technical parameters

Cov pa roj carbon dioxide, ib yam ntawm cov pa roj carbon monoxide, nrog rau cov tshuaj formula CO2, yog cov roj tsis muaj xim, tsis muaj ntxhiab lossis tsis muaj xim tsis muaj ntxhiab tsw nrog cov kua qaub me ntsis hauv nws cov tshuaj aqueous nyob rau hauv ib txwm kub thiab siab. Nws kuj yog ib qho khoom siv hauv tsev cog khoom roj thiab ib feem ntawm huab cua. Ib qho (xws li 0.03%-0.04% ntawm tag nrho cov ntim ntawm cov cua). Hais txog lub cev lub cev, cov pa roj carbon dioxide yog cov roj uas tsis muaj xim thiab tsw ntxhiab ntawm chav tsev kub thiab siab. Nws muaj qhov ntom ntom dua li huab cua thiab soluble hauv feem ntau cov kuab tshuaj organic xws li dej thiab hydrocarbons. Hais txog cov khoom siv tshuaj, ib qho ntawm cov pa roj carbon dioxide cov pa roj carbon monoxide yog cov tshuaj inorganic. Nws yog chemically inactive thiab muaj thermal stability (tsuas yog 1.8% decomposition ntawm 2000 ° C). Nws tsis tuaj yeem hlawv, feem ntau tsis txhawb combustion, thiab yog acidic. Oxides muaj cov khoom zoo ib yam li cov kua qaub oxides. Vim tias lawv hnov ​​​​mob nrog dej los tsim carbonic acid, lawv yog anhydrides ntawm carbonic acid. Hais txog nws cov toxicity, cov kev tshawb fawb tau pom tias cov pa roj carbon dioxide qis tsis muaj tshuaj lom, thaum cov pa roj carbon dioxide siab tuaj yeem ua rau tsiaj txhu. High-purity carbon dioxide yog tsuas yog siv nyob rau hauv lub electronics kev lag luam, kev tshawb fawb kev kho mob thiab kev soj ntsuam kuaj mob, carbon dioxide lasers, calibration gas rau kev ntsuam xyuas cov twj paj nruag thiab kev npaj ntawm lwm yam tshwj xeeb tov roj, thiab nws yog siv raws li ib tug regulator nyob rau hauv polyethylene polymerization. Gaseous carbon dioxide yog siv rau carbonized soft drinks, pH tswj nyob rau hauv dej kho cov txheej txheem, tshuaj ua, zaub mov preservation, inert tiv thaiv nyob rau hauv tshuaj thiab zaub mov ua, vuam roj, cog kev loj hlob stimulant, siv nyob rau hauv hardening pwm thiab cores thiab siv nyob rau hauv casting Pneumatic li. Nws kuj yog siv los ua ib qho diluent rau kom tsis muaj menyuam roj (piv txwv li, kev sib xyaw ntawm ethylene oxide thiab carbon dioxide yog siv los ua kom tsis muaj menyuam, tshuaj tua kab, thiab fumigant. , thiab lwm yam., pob txha noj tshuaj tua kab mob, fumigation ntawm warehouses, factories, kab lis kev cai relics, phau ntawv). Cov kua roj carbon dioxide yog siv los ua cov tub yees, ntsuas kub qis ntawm cov dav hlau, cov foob pob hluav taws thiab cov khoom siv hluav taws xob, txhawm rau txhim kho cov roj zoo rov qab, roj hmab polishing thiab tshuaj tiv thaiv cov tshuaj tiv thaiv, thiab tseem tuaj yeem siv los ua cov tshuaj tua hluav taws.

Daim ntawv thov:

①Industrial Siv:

High-purity carbon dioxide yog tsuas yog siv nyob rau hauv lub electronics kev lag luam, kev tshawb fawb kev kho mob thiab kev soj ntsuam kuaj mob, carbon dioxide lasers, calibration gas rau kev ntsuam xyuas cov twj paj nruag thiab kev npaj ntawm lwm yam tshwj xeeb tov roj, thiab nws yog siv raws li ib tug regulator nyob rau hauv polyethylene polymerization.

②Refrigerant thiab extinguishing:

Cov kua roj carbon dioxide yog siv los ua cov tub yees rau qhov ntsuas kub qis ntawm cov dav hlau, cov cuaj luaj thiab cov khoom siv hluav taws xob, nws kuj tuaj yeem siv los ua tus tua hluav taws.
