Cov lus qhia rau kev siv dej khov qhuav

Khoom Taw Qhia:

Cov dej khov qhuav yog cov khoom siv ntawm cov pa roj carbon dioxide, dav siv hauv kev thauj mus los txias rau cov khoom uas yuav tsum tau muaj qhov kub thiab txias, xws li cov khoom noj, tshuaj, thiab cov qauv tshuaj lom neeg.Cov dej khov qhuav muaj qhov kub tsis tshua muaj siab (kwv yees li -78.5 ℃) thiab tsis muaj qhov seem seem vim nws sublimates.Nws qhov ua kom txias txias thiab qhov tsis muaj kuab paug ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev thauj mus los txias.

Cov kauj ruam siv:

1. Npaj cov dej khov qhuav:

- Hnav cov hnab looj tes tiv thaiv thiab tsom iav kev nyab xeeb ua ntej tuav cov dej khov qhuav kom tsis txhob muaj frostbite los ntawm kev sib cuag ncaj qha.

- Txheeb xyuas qhov xav tau ntawm cov dej khov qhuav qhuav raws li tus naj npawb ntawm cov khoom yuav tsum tau txias thiab lub sijhawm ntawm kev thauj mus los.Nws yog feem ntau pom zoo kom siv 2-3 kilograms ntawm qhuav dej khov rau ib kilogram ntawm cov khoom.

2. Npaj lub Thawv Thauj Khoom:

- Xaiv lub thawv ntim khoom tsim nyog, xws li lub thawv VIP insulated, EPS insulated lub thawv, lossis EPP insulated lub thawv, thiab xyuas kom lub thawv huv si sab hauv thiab tawm.

- Tshawb xyuas lub foob ntawm lub thawv insulated, tab sis xyuas kom muaj qee qhov cua kom tiv thaiv kev tsim cov pa roj carbon dioxide.

3. Chaw thau khoom ntawm cov dej khov qhuav:

- Muab cov dej khov qhuav qhuav los yog pellets rau hauv qab ntawm lub thawv insulated, kom ntseeg tau tias muaj kev faib tawm.

- Yog tias cov dej khov qhuav qhuav loj, siv rauj lossis lwm yam cuab yeej los rhuav tshem lawv mus rau hauv cov khoom me me kom ua rau thaj chaw saum npoo thiab txhim kho kev ua kom txias.

4. Chaw thau khoom tub yees:

- Muab cov khoom uas yuav tsum tau muab tso rau hauv tub yees, xws li zaub mov, tshuaj, lossis cov qauv tshuaj lom neeg, rau hauv lub thawv insulated.

- Siv cov txheej txheem sib cais lossis cov ntaub ntawv cushioning (xws li ua npuas ncauj lossis daim txhuam cev) kom cov khoom tsis txhob cuam tshuam ncaj qha rau cov dej khov qhuav kom tiv thaiv frostbite.

5. Sealing lub thawv Insulated:

- Kaw lub hau ntawm lub thawv insulated thiab xyuas kom meej tias nws raug kaw kom zoo, tab sis tsis txhob muab kaw kom tiav.Cia lub qhov cua me me qhib kom tsis txhob muaj kev kub ntxhov hauv lub thawv.

6. Thauj thiab Cia:

- Tshem lub thawv ntim nrog cov dej khov qhuav thiab cov khoom txias txias rau hauv lub tsheb thauj khoom, tsis txhob raug tshav ntuj lossis kub kub.

- Txo qhov zaus ntawm qhov qhib lub thawv thaum thauj mus los kom tswj tau qhov kub thiab txias.

- Thaum tuaj txog ntawm qhov chaw, tam sim ntawd hloov cov khoom tub yees mus rau qhov chaw cia khoom tsim nyog (xws li lub tub yees lossis lub tub yees).

Cov kev ceev faj:

- Cov dej khov qhuav yuav maj mam sublimate rau hauv cov pa roj carbon dioxide thaum siv, yog li xyuas kom muaj cua zoo kom tsis txhob muaj cov pa roj carbon dioxide lom.

- Tsis txhob siv cov dej khov qhuav qhuav hauv qhov chaw kaw, tshwj xeeb tshaj yog nyob rau hauv cov tsheb thauj khoom, thiab xyuas kom muaj cua txaus.

- Tom qab siv, cov dej khov qhuav uas tseem tshuav yuav tsum tau tso cai rau sublimate nyob rau hauv qhov chaw zoo-ventilated, tsis txhob tso ncaj qha rau hauv qhov chaw kaw.
