Cua activated ( hlau )

Air-activated tes warmers muaj cellulose , hlau , activated carbon , vermiculite (uas tuav dej) thiab ntsev thiab tsim cov cua sov los ntawm exothermic oxidation ntawm hlau thaum raug huab cua.

Ib yam li ntawd, cov ntsiab lus ntawm tes sov so puas txaus ntshai?

COV CHAW UA HAUJ LWM: Plaub tus neeg mob laus tau noj cov tshuaj cov ntsiab lus ntawm tes warmers . Tsis muaj cov ntaub ntawv qhia txog kev noj cov hlau los yog hlau oxides ua rau cov hlau toxicity thiab tsis muaj cov ntaub ntawv luam tawm ntawm kev nqus, tshem tawm, cov teebmeem tsis zoo, lossis tshuaj lom neeg hauv tib neeg tom qab tsis txhob txwm noj. tes warmer txheem.

Tsis tas li ntawd, tes ua kom sov tuaj yeem tawg? Kev siv tsis tsim nyog ntawm rechargeable mini tes ua kom sov tej zaum yuav ua rau tawg thiab raug mob. Raws li qhov kub thiab txias, feem ntau cov neeg siv cov mini tes ua kom sov kom lawv tes sov. Feem ntau ntawm cov no tes ua kom sov emission kub ntawm 45 degrees Celsius mus rau 60 degrees Celsius.

Tsis tas li ntawd, dab tsi yog cov tshuaj tiv thaiv rau tes sov so?

Cov tshuaj tiv thaiv uas ua rau tes sov so Kub Up. Oxygen nyob rau hauv cov huab cua reacts nrog cov hmoov no kom tawm tau hlau oxide-xeb-thiab kub . Cov kub kub no tuaj yeem ncav cuag 163 degrees Fahrenheit; Cov tub rog-qib ua kom sov (rau cua sov MREs) tuaj yeem nce mus txog 200 degrees.

Dab tsi yog qhov zoo tshaj plaws tes warmers?
