Puas yog cov kua dej qhuav qhuav txawv ntawm cov dej khov qhuav qhuav?

Raws li tus kws tshaj lij daim ntawv thov dej khov qhuav nrog ntau tshaj 15 xyoo ntawm kev paub hauv kev lag luam tu thiab kev xa khoom txias, kuv tau nug ntau zaus txog qhov sib txawv ntawm cov ice pellets qhuav thiab cov neeg hu ua "cov dej khov" qhuav. Thaum ob qho tib si yog cov qauv ntawm cov khoom carbon dioxide (CO₂), lawv cov ntaub ntawv lub cev thiab daim ntawv thov sib txawv heev. Hauv phau ntawv qhia dav dav no, kuv yuav piav qhia txog qhov sib txawv tseem ceeb los pab koj nkag siab yam twg uas haum rau koj cov kev xav tau.

Nkag siab txog Cov Qauv Txheej Txheem

Ua ntej, cia peb qhia meej tias seb peb tab tom tham txog cov pellets lossis cov blocks, cov dej khov qhuav yog cov khoom siv carbon dioxide nrog qhov kub ntawm -78.5℃(-109.3℃F). Qhov txias txias no ua rau ob qho tib si sib txawv ntawm cov dej khov nab kuab (H₂O), uas khov ntawm 0℃(32℃F).

Cov tshuaj muaj pes tsawg leeg yog zoo tib yam - ob leeg yog CO₂ nyob rau hauv cov khoom muaj zog. Qhov txawv tsuas yog nyob rau hauv lawv lub cev daim ntawv thiab kev tsim khoom. Cov dej khov qhuav tsis tu ncua feem ntau tuaj hauv cov blocks loj lossis cov hlais, thaum cov dej khov qhuav qhuav me me, cov thooj voos kheej kheej feem ntau yog li ntawm 1.5mm txog 10mm inch.

Cov txheej txheem tsim khoom sib txawv

Cov txheej txheem tsim khoom rau ob daim ntawv no qhia tias vim li cas lawv cov ntawv thov txawv:

Tsis tu ncua Dry Ice (Blocks):

• Tsim los ntawm compressing kua CO₂ nyob rau hauv siab siab (txog 6250.5498 kPa) rau hauv pwm loj
• Feem ntau tsim nyob rau hauv qhov ntau thiab tsawg los ntawm 5kg mus rau 10kg blocks
• Yuav tsum tau tawg lossis txiav rau feem ntau daim ntawv thov
• Daim ntawv ib txwm siv txij li cov dej khov qhuav yog thawj zaug ua lag luam

Qhuav Ice pellets:

• Manufactured siv tshwj xeebqhuav ice pelletizing khoom
• Cov kua CO₂ tau nthuav dav los ntawm cov nozzles rau hauv pellet tuag
• Cov ntaub ntawv zoo ib yam cylindrical hais (feem ntau 1.5-3mm txoj kab uas hla rau kev tu, mus txog 10mm rau txias)
• Npaj-rau- siv daim ntawv uas yuav tsum tsis muaj kev ua haujlwm thib ob
• Kev tsim kho tshiab tsis ntev los no tsim los rau cov ntawv thov kev lag luam tshwj xeeb

Qhov tseem ceeb ntawm lub cev sib txawv

Thaum cov tshuaj zoo ib yam, qhov sib txawv ntawm lub cev ntawm pellets thiab blocks yog qhov tseem ceeb:

Daim ntawv thov sib txawv

Cov ntawv sib txawv ntawm lub cev qiv lawv tus kheej rau kev siv sib txawv hauv kev lag luam:

Qhuav Ice Pellets Excel Hauv:

1. Kev tu vaj tse (Dry Ice Blasting)

• Cov pellets me me (1.5-3mm) yog qhov zoo tagnrho rau kev tu kom huv
• Nws tuaj yeem ua kom nrawm mus rau qhov siab tshaj plaws yam tsis muaj kev puas tsuaj rau substrates
• Siv tau rau kev tshem cov xim, roj, pwm, thiab lwm yam kab mob
• Siv hauv electronics, ilv machinery, thiab precision pwm tu

2. Automated Systems

• Flowable xwm tso cai siv nyob rau hauv automated dispensing systems

• Qhov zoo tshaj plaws rau cov kab ua zaub mov thiab kev siv hauv chav kuaj

3. Cov ntawv thov kho mob & tshawb fawb

• Raws li qhov me me muaj txiaj ntsig zoo rau cov qauv khaws cia
• Yooj yim rau feem rau qhov kub thiab txias -sensitive shipping

Tsis tu ncua qhuav dej khov (Blocks) zoo dua rau:

1. Ntev -Lub caij txias

• Slower sublimation ua blocks zoo tagnrho rau kev xa khoom mus ntev
• Feem ntau hauv kev pabcuam zaub mov, kev thauj tshuaj, thiab khaws cia lub cev

2. Loj -Txheej txheem cua txias xav tau

• Kev lag luam ntau dua rau txias ntim loj
• Siv hauv kev ua yeeb yaj kiab huab cua thiab loj - cov zaub mov loj

3. Heavy-Lub luag haujlwm tu

• Yuav crushed rau daim ntaub ntawv yuav tsum tau nruj dua tu
• Qee lub sij hawm siv rau hauv kev lag luam loj tu daim ntaub ntawv

Kev txiav txim siab txog kev nyab xeeb rau ob daim ntawv

Thaum ob daim ntawv qhia txog kev nyab xeeb zoo sib xws, pellets nthuav tawm qee qhov kev txiav txim siab tshwj xeeb:

Shared Safety Kev txhawj xeeb:

• Qhov txias txias (-78.5 degree) tuaj yeem ua rau muaj mob hnyav heev ntawm kev sib cuag
• Sublimation nthuav dav CO₂ roj 800-1000 npaug qub ntim
• Yuav ua rau asphyxiation nyob rau hauv qhov chaw kaw yog tias qhov cua tsis txaus

Pellet-Kev txiav txim siab tshwj xeeb:

• Qhov chaw siab dua txhais tau tias sublimation sai dua thiab tso pa tawm sai dua
• Qhov me me ua rau muaj kev pheej hmoo ntawm kev sib cuag tsis raug (tuaj yeem thaws thaum lub sijhawm tawg)
• Flowability yuav tsum tau ua tib zoo tuav kom tsis txhob muaj dej nchuav

Thaiv -Kev txiav txim siab tshwj xeeb:

• Cov blocks hnyav ua rau muaj kev pheej hmoo ntawm kev tuav tes
• Txiav / tawg yuav tsum muaj cov cuab yeej tsim nyog thiab PPE
• Cov khoom loj tuaj yeem ua rau mob khaub thuas hnyav dua yog tias siv tsis raug

Cov cuab yeej tiv thaiv tus kheej kom raug (PPE) suav nrog cov hnab looj tes insulated, tiv thaiv qhov muag, thiab kev tiv thaiv ua pa yuav tsum tau siv tas li thaum tuav ob daim ntawv.

Nqi thiab Efficiency Factors

Thaum txiav txim siab ntawm pellets thiab blocks, xav txog cov kev lag luam no:

Qhuav Ice pellets:

• Feem ntau kim dua ib kilogram dua thaiv dej khov
• Cov nqi ntau lawm vim yog cov cuab yeej tshwj xeeb
• Txo cov nqi zog (tsis tas yuav txiav lossis tawg)
• Tsawg pov tseg hauv daim ntawv thov xav tau cov nyiaj tshwj xeeb
• Kev tu ntau dua hauv kev siv blasting

Tsis tu ncua Dry Ice (Blocks):

• Tus nqi qis dua ib kilogram
• Yuav tsum tau ua haujlwm txiav lossis tawg rau feem ntau daim ntawv thov
• Tej zaum yuav ua rau pov tseg ntau dua los ntawm qhov tsis siv
• Lub sijhawm sublimation ntev dua tuaj yeem txhais tau tias tsawg dua rau kev siv cua txias

Cov Khoom Siv Tshwj Xeeb Yuav Tsum Tau

Cov cuab yeej xav tau sib txawv heev ntawm ob daim ntawv:

Rau Dry Ice pellets:

• Pellet- tshwj xeeb blasting tshuab rau tu daim ntaub ntawv
• Tshwj xeeb hoppers thiab feed systems
• Feem ntau yuav tsum tau compressed cua tshuab

• Hammers los yog mallets rau tawg
• Insulated ntim rau cia
• Feem ntau siv nrog cov thawv txias txias

Sublimation tus nqi thiab cia

Qhov sib txawv ntawm thaj chaw ua rau muaj kev cuam tshuam rau sublimation tus nqi:

1. Pellets sublimate sai dua vim qhov raug ntau dua

• Tsis zoo rau kev cia ntev -
• Feem ntau siv tam sim ntawd tom qab ntau lawm
• Cov pellets xoob yuav siv sij hawm tsuas yog teev rau ib hnub nyob rau hauv cov thawv txheem

2. Blocks sublimate qeeb dua

• Muaj peev xwm kawg hnub nyob rau hauv kom zoo cia
• Feem ntau xa mus rau hauv insulated tab sis tsis airtight ntim
• Txaus siab rau ntau- hnub xa khoom

Kev cia kom zoo rau ob qho tib si yuav tsum tau ntim cov thawv uas tso cai rau cov pa tawm thaum khaws cia txias.

Xaiv ntawm Pellet thiab Blocks

Xav txog cov xwm txheej no thaum xaiv daim ntawv twg los siv:

Xaiv Dry Ice pellets Thaum:

• Koj xav tau daim ntawv thov meej (ntxuav lossis txias)
• Automated systems yuav siv tau

Cov lus pom zoo kawg

Tom qab tshuaj xyuas tag nrho cov xwm txheej no, kuv cov lus qhia tshaj lij yog:

1. Rau thawj - cov neeg siv sijhawm, pib nrog cov pellets yog tias ua tau - lawv yooj yim rau kev lis thiab ntsuas.
2. Kev nqis peev hauv cov cuab yeej tsim nyog - sim hloov cov ntawv thov pellet los thaiv cov dej khov (lossis lwm yam) feem ntau ua rau cov txiaj ntsig tsis zoo thiab kev pheej hmoo ntawm kev nyab xeeb.
3. Tham nrog cov neeg muag khoom txog koj cov kev xav tau tshwj xeeb - lawv tuaj yeem pom zoo tus nqi tshaj plaws - daim ntawv zoo.
4. Ib txwm ua qhov tseem ceeb ntawm kev nyab xeeb - ob daim ntawv yog txias heev thiab yuav tsum tau ua kom raug cov txheej txheem.

Thaum cov dej khov pellets qhuav thiab cov dej khov qhuav tsis tu ncua qhia tib yam tshuaj lom neeg muaj pes tsawg leeg, lawv lub cev sib txawv tsim qhov zoo sib xws rau cov ntawv thov tshwj xeeb. Kev nkag siab txog qhov sib txawv no tso cai rau koj xaiv qhov zoo tshaj plaws, ua tau zoo, thiab muaj kev nyab xeeb rau koj cov kev xav tau. Raws li cov tshuab dej khov qhuav txuas ntxiv hloov zuj zus, peb tuaj yeem cia siab tias yuav muaj cov ntawv tshwj xeeb tshaj tawm, ntxiv nthuav dav cov ntawv thov zoo kawg nkaus ntawm cov khoom carbon dioxide.
