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

Barafu kavu inaweza kufanywa na Shuliy wetu mashine ya barafu kavu<\/a><\/strong> na inaweza kuwa pellets kavu za barafu na vipenyo tofauti au vitalu vya barafu vilivyo na unene tofauti. Na kwa kutunza vitalu vya barafu kavu<\/strong> au vidonge vya barafu kavu<\/strong>, tunaweza kutoa maalum sanduku kavu la kuhifadhi joto la barafu<\/a><\/strong> kwa kuhifadhi barafu kwa muda mrefu. Kando na hilo, mashine kavu ya kulipua barafu pia inauzwa kwa moto katika kiwanda chetu cha mashine kavu ya barafu, ambayo ina miundo tofauti na uwezo wa kufanya kazi ili tuweze kukusaidia kuchagua inayofaa zaidi.<\/p>\n\n\n\n

Barafu kavu ni hali ngumu ya dioksidi kaboni. Kwa sababu halijoto ya barafu kavu ni ya chini sana, halijoto ni minus 78.5 \u00b0 C, hivyo mara nyingi hutumiwa kuweka vitu katika hali iliyoganda au chini ya joto.\u00a0Kila wakati unapogusa barafu kavu, kuwa mwangalifu na utumie glavu nene au vifuniko vingine kugusa barafu kavu! Wakati ngozi ya binadamu inagusa barafu kavu<\/strong> kwa muda mrefu moja kwa moja, inaweza kusababisha seli kufungia na kufanana na baridi ndogo au kali. Kwa hiyo, tunapaswa kuwa makini wakati wa kutumia barafu kavu. Zifuatazo ni baadhi ya tahadhari za kutumia barafu kavu kwa usalama.<\/p>\n\n\n\n

  1. Usiguse barafu kavu moja kwa moja na mikono yako. Vaa glavu za kinga ili kuzuia baridi!<\/li>
  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>\n\n\n\n

    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>\n\n\n\n

     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":"
