I-Isopropyl alcohol, eyaziwa ngokuba yi-rubbing alcohol, sisibulala-ntsholongwane esisetyenziswa ngokubanzi kunye nearhente yokucoca. Ifumaneka kwiindawo ezimbini eziqhelekileyo: i-70% kunye ne-91%. Umbuzo uhlala uvela kwiingqondo zabasebenzisi: yiyiphi enye endimele ndiyithenge, i-70% okanye i-91% ye-isopropyl alcohol? Eli nqaku lijolise ekuthelekiseni kunye nokuhlalutya okugxininiso kubini ukukunceda wenze isigqibo esinolwazi.

Ukuqala, makhe sijonge umahluko phakathi kwezi zigxinaniso zimbini. I-70% ye-isopropyl alcohol iqukethe i-70% isopropanol kunye ne-30% eseleyo ngamanzi. Ngokufanayo, i-91% isopropyl alcohol iqukethe i-91% isopropanol kunye ne-9% eseleyo ngamanzi.

Ngoku, makhe sithelekise ukusetyenziswa kwazo. Zombini izigxina ziyasebenza ekubulaleni ibhaktheriya kunye neentsholongwane. Nangona kunjalo, uxinzelelo oluphezulu lwe-91% ye-isopropyl yotywala lusebenza ngakumbi ekubulaleni iibhaktheriya ezomeleleyo kunye neentsholongwane ezixhathisayo ekugxininiseni okuphantsi. Oku kwenza kube lukhetho olungcono lokusetyenziswa ezibhedlele nasezikliniki. Ngakolunye uhlangothi, i-70% ye-isopropyl alcohol ayisebenzi kangako kodwa isasebenza ekubulaleni iibhaktheriya ezininzi kunye neentsholongwane, okwenza kube lukhetho olufanelekileyo kwiinjongo zokucoca indlu ngokubanzi.

Xa kuziwa kuzinzo, i-91% ye-isopropyl alcohol ineqondo eliphezulu lokubilisa kunye nesantya esisezantsi sokunyuka komphunga xa kuthelekiswa ne-70%. Oku kuthetha ukuba ihlala isebenza ixesha elide, nokuba ibekwe kubushushu okanye kukukhanya. Ngoko ke, ukuba ufuna imveliso ezinzileyo, i-91% ye-isopropyl alcohol yinto engcono kakhulu.

Nangona kunjalo, kufuneka kuqatshelwe ukuba zombini ugxininiso lunokutsha kwaye kufuneka luphathwe ngononophelo. Ukongeza, ukuvezwa ixesha elide kuxinzelelo oluphezulu lwe-isopropyl yotywala kunokubangela ukucaphukisa ulusu kunye namehlo. Ke ngoko, kubalulekile ukulandela imiyalelo kunye namanyathelo okhuseleko anikezelwe ngumenzi.

Ekugqibeleni, ukhetho phakathi kwe-70% kunye ne-91% ye-isopropyl alcohol ixhomekeke kwiimfuno zakho ezithile. Ukuba ufuna imveliso esebenzayo ngokuchasene neebhaktheriya ezinzima kunye neentsholongwane, ngakumbi kwizibhedlele okanye iikliniki, i-91% ye-isopropyl alcohol iyona ndlela engcono. Nangona kunjalo, ukuba ukhangele i-arhente yokucoca indlu ngokubanzi okanye into engasebenzi kakuhle kodwa isasebenza kwiibhaktheriya ezininzi kunye neentsholongwane, i-70% ye-isopropyl alcohol ingaba lukhetho oluhle. Okokugqibela, kubalulekile ukulandela amanyathelo okhuseleko anikezelwe ngumenzi xa usebenzisa nayiphi na inxinaniso ye-isopropyl alcohol.
