Khoom Taw Qhia:
Cov dej khov qhuav yog cov khoom tawv nqaij ntawm cov pa roj carbon dioxide, xws li cov khoom noj txias rau cov khoom uas yuav tsum muaj cov khoom noj muaj cov khoom noj tsawg, tshuaj xyuas cov chaw muag khoom. Cov dej khov qhuav muaj qhov kub tsis tshua muaj cua sov (kwv yees -78.5 ℃) thiab nplooj tsis muaj qhov seem raws li nws sublimates. Nws lub siab txias ua haujlwm thiab tsis muaj kuab lom ua rau nws xaiv qhov kev xaiv hloov chaw txias.
Cov kauj ruam siv:
1. Npaj cov dej khov qhuav:
- Cov hnab looj tes hnab looj tes tiv thaiv kev tiv thaiv thiab kev tiv thaiv kev nyab xeeb ua ntej tuav dej khov kom qhuav kom tsis txhob muaj tus mob frostbite los ntawm kev sib cuag.
- suav qhov yuav tsum tau muaj ntawm cov dej khov qhuav raws cov naj npawb ntawm cov khoom kom yuav tsum nyob hauv tub yees thiab lub sijhawm thauj mus los. Nws feem ntau pom zoo kom siv 2-3 kilo dej khov rau ib kiloGram ntawm cov khoom.
2. Npaj lub thawv thauj khoom:
- Xaiv cov thawv uas haum xim, xws li lub thawv insulated roulated, lossis EPP pastulated lub thawv, thiab xyuas kom cov thawv muaj huv sab hauv thiab sab nraud.
- Txheeb xyuas cov ntim ntawm cov pob tawb insulated, tab sis xyuas kom muaj qee qhov cua ua kom tiv thaiv cov pa roj carbon dioxide.
3. Loading cov dej khov qhuav:
- Tso cov dej khov qhuav los yog pellets nyob hauv qab ntawm cov thawv insulated, kom ntseeg tau ib qho kev faib tawm.
- Yog hais tias cov dej khov khov khov loj, siv rab rauj lossis lwm yam cuab yeej los ua kom lawv ua rau thaj chaw me me kom nce thaj chaw txias.
4. Chaw thau tawm cov khoom hauv tub yees:
- Tso cov khoom uas yuav tsum tau muab tso rau hauv tub yees, xws li khoom noj, cov chaw muag tshuaj, lossis cov thawv tshuaj insulated, mus rau hauv cov thawv insulated.
- Siv cov khoom sib cais lossis cov ntaub ntawv cushioning (xws li ua npuas ncauj (xws li cov npuaj lossis kab nrig) kom cov khoom los ntawm kev tiv thaiv qhuav kom tiv thaiv kom khov.
5. Sib khi cov thawv insulated:
- Kaw lub hau ntawm cov thawv insulated thiab xyuas kom meej nws tau muab khi kom zoo, tab sis tsis txhob ntim nws tag nrho. Tso tawm hauv qhov cua me me qhib kom tiv thaiv kev kub siab tsim hauv lub khob.
6. Thauj thiab cia:
- Txav cov thawv insulated nrog cov dej khov qhuav thiab cov khoom hauv tub yees mus rau lub tsheb thauj khoom, zam kev ua lub hnub ci lossis kub.
- Txo qhov tsawg zaus ntawm qhib lub ntim thaum thauj khoom los tswj qhov kub thiab txias ruaj khov.
- Thaum tuaj txog ntawm lub hom phiaj, kom sai hloov cov khoom hauv tub yees kom muaj chaw cia khoom tsim nyog (xws li lub tub yees lossis txias).
Cov kev ceev faj:
- Qhuav dej khov yuav maj mam subtlate rau cov pa roj carbon dioxide thaum siv, yog li paub tseeb qhov cua kom tsis txhob muaj cov pa roj carioxide.
- Tsis txhob siv cov dej khov ntau ntawm cov dej khov kom qhuav hauv cov chaw uas ntim, tshwj xeeb tshaj yog nyob hauv tsheb thauj khoom, thiab ua kom muaj qhov cua txaus.
- Tom qab siv tas los, ib qho dej khov uas tseem tshuav rau subtumate hauv qhov chaw muaj pa zoo, tsis txhob tso tawm ncaj qha rau hauv qhov chaw.
