Qhuav dej khov blastingyog ib qho muaj zog, eco-txoj kev tu tus phooj ywg uas siv cov khoom CO₂ pellets kom tshem tawm cov av, roj, thiab cov kab mob tsis muaj qhov seem. Yog tias koj muaj lossis ua haujlwm lub tshuab ziab khaub ncaws qhuav, tej zaum koj yuav pom tias tsis yog txhua qhov dej khov pellets ua tau zoo ib yam. Qhov sib txawv feem ntau los txog rau ob yam tseem ceeb: pellet loj thiab compression ratios (uas cuam tshuam rau pellet ntom).
Kev tau txais cov cai no tuaj yeem ua rau koj ntxuav sai dua, muaj txiaj ntsig zoo dua, thiab tsis siv nyiaj tsawg. Hauv tsab xov xwm no, peb yuav rhuav nws hauv cov ntsiab lus yooj yim los pab koj xaiv qhov zoo tshaj plaws qhuav ice pellets rau koj xav tau.

Common Dry Ice Pellet Sizes
Qhuav ice pellets tuaj nyob rau hauv ntau txoj kab uas hla, feem ntau yog li ntawm 3 hli mus rau 19 hli. Qhov nrov tshaj plaws rau blasting yog cov me me.
Ntawm no yog ib tug ceev txheej txheem cej luam:
(Piv txwv ntawm qhov sib txawv ntawm cov dej khov qhuav qhuav - cov pellets me me zoo li 3 hli yog qhov zoo tagnrho rau feem ntau cov ntawv thov blasting)
- 3mm pellets - Cov qauv xaiv rau feem ntau cov tshuab ziab khaub ncaws qhuav. Lawv me me txaus kom ntws zoo los ntawm cov nozzles tab sis muaj kev cuam tshuam txaus rau kev tu kom zoo.
- 6mm mus rau 9mm - Ib qho loj me me, muab kev tu nruj dua tab sis muaj kev pheej hmoo siab ntawm clogging me me nozzles.
- 16mm txog 19mm - Feem ntau yog siv rau tsis yog- blasting siv xws li shipping lossis txias, vim lawv loj dhau rau cov khoom siv blasting.
Vim li cas qhov loj me? Cov pellets me me (tshwj xeeb tshaj yog 3 hli) muab kev tswj kom zoo dua thiab txawm tias muaj kev tiv thaiv, thaum cov loj loj tuaj yeem ua rau cov txiaj ntsig tsis sib xws los yog txhaws.
Compression Ratios txhais li cas rau Pellet ntom
Compression ratio yog hais txog nruj npaum li cas cov dej khov qhuav "snow" yog nias rau hauv pellets thaum lub sij hawm tsim khoom. Kev compression siab dua tsim cov pellets denser - xav txog nws zoo li ntim cov pob snow pob khov kho tiv thaiv xoob.
Dense pellets (around 1.3–1.45 g/cm³) last longer in flight, hit harder, and turn into gas (sublimate) more slowly. Looser pellets tawg yooj yim dua thiab ploj sai dua.
(High- ntom ntom pellets sublimate qeeb qeeb, txo cov khib nyiab thaum tawg)
Cov txiaj ntsig ntawm siab - ntom ntom pellets:
- Lub zog tu lub zog tsis muaj kev txhoj puab heev.
- Tsawg dej khov qhuav siv rau ib txoj haujlwm - feem ntau 20-30% kev txuag nyiaj.
- Tsawg kev cuam tshuam los ntawm crumbling pellets.
Yuav ua li cas pellet loj thiab compression ua hauj lwm ua ke
Cov txiaj ntsig zoo tshaj plaws yog los ntawm qhov sib txuam loj thiab qhov ntom ntom. Rau cov neeg siv feem ntau, 3 hli siab - ntom ntom pellets yog qhov chaw qab zib:
- Lawv haum txig rau hauv cov qauv blasting nozzles.
- High compression ua kom lawv nyob twj ywm ntev rau qhov siab tshaj plaws.
- Zoo sib npaug rau kev tu txhua hnub.
Cov teeb meem tshwm sim los ntawm kev sib tw tsis zoo:
- Loj dhau / tsawg ntom → Nrawm nozzle clogs thiab tsis muaj zog tu.
- Tsawg heev / tsawg ntom → Pellets tawg hauv nruab nrab- huab cua, txo cov txiaj ntsig.
