Txoj ice qhuav
dej khov qhuav yog hu ua cov khoom ntawm carbon dioxide. Tsis zoo li cov dej khov zoo tib yam, nws ib txwm hloov mus rau hauv cov roj, hla cov kua dej.
Cov txheej txheem ntawm kev hloov mus rau lub xeev gaseous hu ua sublimation. Nyob rau hauv tas li ntawd, cov dej khov hloov mus rau hauv ib tug tuab vapor uas tsis muaj ib tug pronounced tsw.
Txawm tias nyob hauv huab cua luv luv ua rau sublimation. Nws tshwm sim sai heev. Piv txwv li, thaum thauj cov khoom nyob rau hauv cov thawv tshwj xeeb, muaj qhov ntim poob li ntawm 10% hauv 24 teev. Nyob rau hauv rooj plaub ntawm kev ua txhaum ntawm qhov tsim nyog tej yam kev mob, qhov taw qhia no nce.
Yog vim li cas nws tseem ceeb kom paub: yuav ua li cas khaws dej khov qhuavyog.
Txoj cai thiab nta ntawm kev cia
Tshwj xeeb isothermal ntim yog siv los khaws cov khoom. Lawv yog ua los ntawm multilayer phab ntsa. Lub luag haujlwm ntawm cov thawv no yog cais cov dej khov qhuav los ntawm huab cua hauv huab cua thiab ncua cov txheej txheem sublimation kom ntau li ntau tau.
- Lub thawv ntim dej khov qhuav tuaj yeem yuav tam sim nrog kev yuav khoom. Los yog, thaum yuav, xauj nws rau lub sijhawm xav tau. Ntau lub tuam txhab muab qhov kev xaiv no.

Kev siv cov khoom siv sab hauv tsev hauv qhov ntim loj tuaj yeem ua rau muaj zog ntawm cov pa roj carbon dioxide. Qhov no yuav ua rau kiv taub hau lossis ua tsis taus pa.
ntsuas kev nyab xeeb rau kev cia thiabsiv dej khov qhuav
Nws yog ib qho tseem ceeb tsis yog kom paub khaws cov dej khov qhuav xwb, tab sis kuj yuav tsum paub koj tus kheej nrog cov cai rau kev siv. Kev tuav tsis tu ncua ntawm cov khoom yuav ua rau kub hnyiab lossis frostbite:

- Npog koj lub ntsej muag nrog lub ntsej muag lossis tsom iav los tiv thaiv koj ob lub qhov muag.
- Tsis txhob muab cov khoom tso rau hauv airtight, kaw kom nruj. Kev sib sau ntawm cov pa roj carbon dioxide maj mam nce siab hauv lub thawv. Qhov no yuav ua rau muaj kev tawg. Txwv tsis pub, tus neeg uas qhib lub hau yuav raug mob ntawm tes thiab ntsej muag.
- Qhov chaw khaws dej khov qhuav yuav tsum tawm ntawm cov menyuam yaus lossis tsiaj.
- Yog qee cov dej khov qhuav tseem tsis tau siv, nws yuav tsum muab pov tseg los ntawm evaporation.
Lawv yuav tsum ua los ntawm cov khoom ntom ntom. Nyias, hnab looj tes roj hmab yuav siv tsis tau thiab tsis muaj kev tiv thaiv.
Yuav dej khov qhuav li cas thiaj yuav thiab siv
Cov khoom yog yuav ntau hom, nyob ntawm qhov chaw:
- Blocks lossis slabs ntawm 1 txog 40 kg.
- Granules nyob rau hauv daim ntawv ntawm lub tog raj kheej me me.
- Fine feem, txoj kab uas hla ntawm 1.5 txog 3 hli.
Koj tuaj yeem yuav cov khoom lag luam los ntawm ntau lub tuam txhab, qee zaum xa khoom sai. Yog tias tsis muaj qhov chaw nyob ze los yuav cov dej khov qhuav, koj tuaj yeem ua rau koj tus kheej.
