Imwe nguva yapfuura, iyo US "Wall Street Journal" yakashuma kuti kuuya kwejekiseni kwakatarisana nebhodhoro: kuperevedza kwegirazi mabhodhoro ekuchengetedza uye yakakosha girazi sezvo mbishi zvinhu zvinotadzisa kugadzirwa kwakawanda. Saka iri bhodhoro regirazi diki rine zvehunyanzvi zvemukati here?
Sechinhu chekurongedza chinobata zvakanangana nemishonga, mabhodhoro egirazi emishonga anoshandiswa zvakanyanya mumunda wemishonga yekurongedza zvinhu nekuda kwekuita kwavo kugadzikana, senge vials, ampoules, uye infusion mabhodhoro egirazi.
Sezvo mabhodhoro egirazi emishonga ari kusangana nemishonga, uye mamwe anofanirwa kuchengetwa kwenguva yakareba, kuenderana kwemabhodhoro egirazi emishonga nemishonga kunoenderana nemhando yemishonga, uye inosanganisira hutano hwemunhu uye chengetedzo.
Iyo girazi yekugadzira mabhodhoro maitiro, kuregeredza mukuyedzwa uye zvimwe zvikonzero zvakakonzera mamwe matambudziko mumunda wekurongedza kwemishonga mumakore achangopfuura. Eg:
Asidhi isina kunaka uye alkali kuramba: Kana ichienzaniswa nezvimwe zvinhu zvekurongedza, girazi harina kusimba mukupikisa asidhi, kunyanya alkali kuramba. Kana imwe nguva kunaka kwegirazi kukundikana, kana zvinhu zvakakodzera hazvina kusarudzwa, zviri nyore kuisa pangozi kunaka kwemishonga uye kunyange hutano hwevarwere. .
Maitiro akasiyana ekugadzira ane akasiyana mhedzisiro pamhando yezvigadzirwa zvegirazi: magirazi ekurongedza midziyo inowanzo gadzirwa nekuumbwa uye inodzorwa maitiro. Nzira dzakasiyana dzekugadzira dzine simba guru pahutano hwegirazi, kunyanya pakupikisa kwemukati wepamusoro. Naizvozvo, kusimbaradza kudzora kwekutarisa uye zviyero zvekushanda kwegirazi bhodhoro remishonga yekurongedza zvinhu zvine simba rakakosha pamhando yekurongedza kwemishonga uye kusimudzira indasitiri.
Izvo zvakakosha zvemabhodhoro egirazi
Mabhodhoro egirazi emushonga ekurongedza zvinhu anowanzo aine silicon dioxide, boron trioxide, aluminium oxide, sodium oxide, magnesium oxide, potassium oxide, calcium oxide uye zvimwe zvinongedzo.
Ndeapi matambudziko nemabhodhoro egirazi
Kunaya kwemienzaniso yealkali simbi (K, Na) mugirazi inotungamira mukuwedzera kweiyo pH kukosha kweindasitiri yemishonga.
Magirazi emhando yakaderera kana kukukurwa kwenguva refu kwezvinwiwa zvine alkaline kunogona kukonzera kusvuuka: kusvuura girazi kunogona kuvhara tsinga dzeropa zvokonzera thrombosis kana pulmonary granulomas.
· Kunaya kwezvinhu zvinokuvadza mugirazi: zvinhu zvinokuvadza zvinogona kuvepo mukugadzira girazi formula
· Aluminium maion anonaya mugirazi ane mhedzisiro yakaipa pabiological agents
Kuongorora ma electron microscopy anonyanya kuona kukukurwa uye kusvuura kwemukati mebhodhoro regirazi, uye inogona zvakare kuongorora kemikari yemvura sefa. Isu tinoshandisa Feiner desktop scanning electron microscope kuti titarise pamusoro pebhodhoro regirazi, sezvakaratidzwa muMufananidzo 1. Mufananidzo wekuruboshwe unoratidza mukati mebhodhoro regirazi rakasvibiswa nemushonga wemvura, uye mufananidzo wekurudyi unoratidza nzvimbo yemukati yemvura. girazi bhodhoro rine nguva yakareba yekukukurwa. Mvura inopindirana nebhodhoro regirazi, uye iyo yakatsetseka yemukati inosvibiswa. Kuora kwenguva refu kunokonzeresa nzvimbo yakakura yekudonha. Kamwe mushonga wemushonga mushure mekuita uku kwave kubaiwa mumuviri wemurwere, unova nemhedzisiro yakaipa pahutano hwemurwere.
