Wakati gesi ya dioksidi kaboni inaposhinikizwa hadi takriban 101,325 Pa kwa joto la chumba, sehemu ya mvuke wa dioksidi kaboni inapopozwa hadi takriban -78 \u00b0 C, inaganda kuwa dioksidi kaboni imara kama theluji. Dioksidi kaboni iliyoganda ina nishati kubwa ya kupeperusha mvuke (heat of vaporization), ambayo ni 364.5 J\/g kwa -60 \u00b0 C. Inapokuwa gesi tena chini ya shinikizo la kawaida, joto la mazingira linaweza kupunguzwa hadi takriban -78 \u00b0 C, na hakuna kioevu kinachotokana, kwa hivyo inaitwa \u201cdry ice<\/strong>\u201c. <\/p>

Jinsi ya kutengeneza barafu kavu?<\/strong><\/strong><\/h2>

Barafu kavu inaweza kutengenezwa na mashine yetu ya barafu kavu ya Shuliy na inaweza kuwa vipande vya barafu kavu vya kipenyo tofauti au vitalu vya barafu kavu vya unene tofauti. Na kwa ajili ya kuhifadhi vitalu vya barafu kavu au vipande vya barafu kavu, tunaweza kutoa kisanduku maalum cha kuhifadhi joto cha barafu kavu kwa ajili ya kuhifadhi barafu kavu kwa muda mrefu. Zaidi ya hayo, mashine ya ulipuaji wa barafu kavu pia inauzwa sana katika kiwanda chetu cha mashine za barafu kavu, ambayo ina mifumo tofauti na uwezo wa kufanya kazi ili tuweze kukusaidia kuchagua inayofaa zaidi.<\/p>

Kuwa salama unapotumia barafu kavu<\/strong><\/strong><\/h2>

Barafu kavu ni hali imara ya kaboni dioksidi. Kwa sababu joto la barafu kavu ni la chini sana, joto ni nyuzi joto 78.5 Selsiasi, kwa hivyo mara nyingi hutumiwa kuweka vitu katika hali iliyogandishwa au ya joto la chini. Kila wakati unagusa barafu kavu, kuwa mwangalifu na utumie glavu nene au vifuniko vingine kugusa barafu kavu! Wakati ngozi ya binadamu inagusana na barafu kavu kwa muda mrefu moja kwa moja, inaweza kusababisha seli kuganda na kufanana na kufungia kidogo au kwa ukali. Kwa hivyo, tunapaswa kuwa waangalifu tunapotumia barafu kavu. Yafuatayo ni tahadhari kadhaa za kutumia barafu kavu kwa usalama.<\/p>

  2. Itakuwa bora kuacha nafasi kati ya bidhaa unayotaka kupoe vizuri\u00a0kwa barafu kavu.<\/li>
  3. Hairuhusiwi kufunga barafu kavu kwenye chombo cha chupa\u00a0kwa kuziba vizuri.<\/li>
  4. Kuwa na uingizaji hewa mzuri mahali ambapo barafu nyingi kavu huwekwa.<\/li><\/ol>

    Baada ya baridi, tunapaswa kuhamia haraka mahali pa joto ili kudumisha sehemu iliyoathirika katika hewa ya joto na kavu. Frostbite huwekwa kwenye maji ya joto yaliyorekebishwa hatua kwa hatua (digrii 38.8 ~ 40.5) kwa ajili ya kuhifadhi joto. Haiwezi kuwa wazi kwa baridi, kuinua sehemu iliyoathirika ili kupunguza maumivu na uvimbe, kisha kufunika sehemu iliyoathirika na chachi safi, na kisha kupelekwa hospitali kwa matibabu.<\/p>

     Madhumuni ya dharura ni kurudisha haraka maji baridi ya mwili kuwa ya kawaida. Kwa hiyo, ikiwa eneo la jirani la sehemu iliyoathiriwa inakuwa joto, baridi itaponywa haraka. Ni marufuku kuingiza sehemu iliyoathiriwa moja kwa moja ndani ya maji ya moto au kutumia moto ili kuoka sehemu iliyoathiriwa, ambayo itaongeza baridi. Kumbuka usifanye massage kwenye eneo lililoathiriwa.<\/p>","protected":false},"excerpt":{"rendered":"
