Mhlawumbi ubhubhane weSARS-CoV-2 wenze wonke umntu ukuba azi ngakumbi ngempilo. Amaphulo angaphambili e-coronavirus ebandayo kunye nentsholongwane yomkhuhlane ngoku sele idityaniswe yiCovid-19 entsha. Umahluko phakathi kwengqele eqhelekileyo kunye nomkhuhlane okanye iCovid-19 kunokuba kubushushu. Ke ngoko, kufuneka ithemometha elungileyo yegaliyamu ekhaya inokuba licebo elihle ngoku kunakuqala.
Ezi thermometers zegalcium azidingi iibhetri, ke ziya kuba njalo isoloko ifumaneka xa uyidinga. Ukongeza, njengoko bengekho kwidijithali, kulula kakhulu ukuzisebenzisa, nkqu ngabantu abadala abakufumanisa kunzima ukuqonda iithemometha zale mihla. Kwaye okona kubaluleke kakhulu, abasenayo ingozi yeemhemomomer esekwe kwi-mercury, kuba i-gallium ayinetyhefu njenge-Hg.
Yintoni i-gallium thermometer?
Un termómetro de galio es un dispositivo para medir la temperatura similar a los primitivos termómetros de mercurio, solo que no emplean el peligroso metal químico que ha quedado prohibido por su toxicidad. En su lugar basebenzisa i-gallium, okanye mandithi, basebenzisa ingxubevange engamanzi ebizwa ngokuba yigalinstan.
Indlela ye ukusebenza kubaluleke kakhulu. Ibhalbhu yentsimbi, apho kugcinwa khona igalinstan, xa idibana nomphezulu oshushu, njengomzimba womntu, uya kwanda. Oko kuyakuqhubela isinyithi esingamanzi ngombhobho onesikali seqondo lobushushu. Oko kuyakuyizisa kwinqanaba lobushushu eliyifumanayo, ukuze uxele ukuba unayo okanye awunayo ifiva.
Oko kukuthi, ngokufanayo nezo zisebenzisa i-mercury, kodwa ayisiyityhefu. Ngapha koko, European Union Kwavalwa zonke iintlobo zezixhobo ezisebenzisa i-mercury ngo-2009. Ukusukela ngoko kuye kwavunyelwa ukuthengisa olu hlobo lwethemometha, endaweni yalo kufakwe ezo zenziwe ngealloyum alloy.
I-alloy, galinstanNgokusisiseko lulwelo oludibanisa i-gallium, i-indium kunye ne-tin, eyenza ukuba ihlale ikwimeko engamanzi kubushushu begumbi kwaye ihloniphe ngakumbi okusingqongileyo kwaye ngaphandle kwetyhefu ukuba bayaphula baze badibane nawe. Kananjalo abayi kuyila i-amalgams ngezinto zegolide, njengoko bekunjalo nge-mercury, ke izacholo zakho ziya kukhuseleka.
Ukongeza, i ukuthembeka okanye ubuntununtunu Ezi thermometer azitshintshwanga ngokufakwa endaweni yemekyuri. Zichanekile kakhulu, kuba zinokwahluka nge-0.1ºC kuphela kwimilinganiselo.
Usebenzisa njani i-gallium thermometer?
I-gallium thermometer, okanye i-galinstan, isetyenziswa ngokuchanekileyo njenge-mercury thermometer. Oko kukuthi, yithemometha leyo ufuna ukunxibelelana, ngokwahlukileyo kugqirha wamehlo. Amanyathelo enkqubo yokusetyenziswa ngokufanelekileyo ngala:
- Ngaphambi kokuba uqale umlinganiso, bamba ithemometha ngentla kwayo kwaye uyihlukuhle ngeentshukumo ezikhawulezayo ngesihlahla kunye nokunyamekela ukuba ungabethi nantoni na okanye uwe. Oku kuya kunceda ekuqinisekiseni ukuba iqondo lobushushu liyehla liye kuma-35ºC.
- CBeka ithemometha kwindawo ekhethiweyo ukulinganisa ubushushu, ngokukhethekileyo ekhwapheni lococeko (ezinye iindlela, ezinje ngomlinganiso emlonyeni okanye kwi-rectum ziya kubandakanya ukubulala iintsholongwane ngokwaneleyo ngamanzi kunye nesepha yokubulala iintsholongwane).
- Lindela ixesha malunga nemizuzu emi-3 kwaye ujonge ubushushu obuphawulayo.
Durante inkqubo umlinganiso akufuneki ulahle unxibelelwano nomphezulu womzimba apho ubekwe khona. Ukongeza, isigulana kufuneka siphumle, ngaphandle kokuba senze imisebenzi yomzimba ngaphambili, kuba inokutshintsha umlinganiso. Ukongeza, ukuba iyasetyenziswa emlonyeni, iintshukumo ezinjengokutshaya, okanye ukutya ukutya okanye iziselo ezinokutshintsha iziphumo.
Kwimeko apho ithemometha iyaphuka, subanexhala. Njengoko ingenayo i-mercury, ayiyi kuba yingozi. Kufuneka uthabathe amaqhekeza kwaye uhlambulule indawo enamabala e-galinstan ngephepha lokufunxa elifakwe etywaleni.
