In recent years, with the progress and maturity of dry ice manufacturing technology, a large number of dry ice products have become an important product with a wide range of industrial and commercial applications, especially in food freezing and transportation, hardware parts manufacturing, kusafisha barafu kavu, and many other usages, dry ice products are widely used now.
Dioksidi kaboni kwa joto la chumba na shinikizo ni gesi isiyo na rangi na yenye harufu nyepesi, ambayo pia ni gesi ya joto la nyumba na mojawapo ya vipengele vya hewa (0.03-0.04% ya jumla ya ujazo wa anga). Dioksidi kaboni ni kiungo muhimu katika mzunguko wa kaboni, na ni chanzo pekee cha kaboni kwa hydrocarbons za kilimo; Ni malighafi muhimu kwa kuendeleza ukuaji wa mimea. Pia inadhibiti joto jumla la dunia.
Barafu kavu ni sawa na dioksidi kaboni
Barafu kavu pia inaweza kuitwa dioksidi kaboni ngumu. Katika shinikizo la kawaida la anga, kiwango cha kuganda cha kaboni dioksidi ni chini ya digrii 78.5, ambayo ni muhimu kwa kuweka vitu vilivyogandishwa au kwenye joto la chini. Ili kugeuza kaboni dioksidi kuwa kioevu, lazima iwe na shinikizo kwa angahewa 5.1. Barafu kavu haina rangi, haina ladha, haiwezi kuwaka na ina asidi kidogo. Barafu kavu hutofautiana katika msongamano lakini kwa kawaida ni takriban 1.4 hadi 1.6 g/cm3. Barafu kavu inaweza kufungia haraka na vitu baridi. Sasa barafu kavu imekuwa sana kutumika katika ngazi nyingi, barafu kavu katika ongezeko la joto ni usablimishaji moja kwa moja kutoka imara hadi gesi, moja kwa moja ndani ya gesi na kuruka mchakato wa kioevu. Sifa hii ya kipekee ya barafu kavu inamaanisha kwamba chembe za barafu kavu zinaponyunyiziwa kwenye uso wa kitu, zitatoweka tu, na kuacha uchafu wa asili tu kusafishwa.
Maombi ya barafu kavu
Viwango vya barafu kavu vinavyotumika kusafisha ni sawa na vile vinavyotumika katika tasnia ya chakula na vinywaji na vimeidhinishwa na FDA, EPA, na USDA. Dioksidi kaboni ni gesi isiyo na sumu, iliyoyeyushwa ambayo ni ya bei nafuu na rahisi kuhifadhi mahali pa kazi. Muhimu vile vile, haifanyi umeme na haina kuchoma.
Dioksidi kaboni ni zao la asili la michakato mingi ya viwandani, kama vile uchachishaji na usafishaji wa mafuta. Dioksidi kaboni inayozalishwa katika mchakato inaweza kukusanywa na kuhifadhiwa kwa matumizi inapohitajika. Chembe za barafu kavu huteleza nyuma kwenye angahewa wakati wa mchakato wa kusafisha, hazitoi kaboni dioksidi mpya, lakini ikitoa bidhaa asili ya kaboni dioksidi.
To produce dry ice in different forms, you can use kavu ya barafu pelletizer for granular dry ice or mashine kavu ya kuzuia barafu for solid dry ice blocks.
