Ingaba iilabhoratri iwasha glassware oluzenzekelayo"umncedi" okanye "irhafu ye-IQ"?Simeme umntu ovavanya elebhu ukuba abelane ngamava akhe kwaye abone ukuba uza kuthini na.

Imibono yabahloli belabhoratri kumaziko ovavanyo lokutya:

Sasidla ngokwenza imifuniselo yokuhlola, yaye eyona nto yayisenza sikhathazeke kukucocwa kweebhotile.Xa siqhuba uhlolo lwesampulu ekutyeni, siya kufumanisa ukugqithisa kwezinto ezininzi ezinobungozi ezifana ne-nitrite kunye neentsalela ze-pesticides ekutyeni.Emva kokuba i-laboratory iphelile, ii-pipettes ezisetyenzisiweyo, ii-beakers kunye nezinye izitya kufuneka zicocwe ngesandla.Kukho iibhotile ezinamabala amaninzi e-oyile ekunzima ukuwacoca, kwaye ahlanjwe ngamanzi amaninzi acocekileyo kunye namanzi epompo ngexesha, kodwa ayikacoceki ngokwaneleyo.Kwaye sihlala sixakeke kakhulu emsebenzini, ngoko ke sinokucudisa kuphela ixesha lokusebenza ixesha elongezelelekileyo kwaye sihlale kude kube sebusuku ukujongana nezi bhotile zinzima.

Emva kokongeza aumatshini wokuhlamba iibhotile owenziwe elabhoratrikwilabhoratri yethu, yasombulula ingxaki enkulu kuthi.Siqhele ukuhlamba iibhotile ngesandla malunga 5 iiyure, kunyeumatshini wokuhlamba iibhotileungazicoca ngemizuzu engama-45.Isixhobo sinenkqubo yokomisa, kwaye iibhotile ezihlanjiweyo ziyafana nezintsha.Umatshini uneentlobo ezininzi zeenkqubo zokucoca ezinokukhethwa ngokukhululekileyo, kwaye kukho neenkqubo ezininzi zokucoca ezenziwe ngokwezifiso.I-ejenti yokucoca ekhethekileyo esetyenzisiweyo yisisombululo esigxininisiweyo, kwaye i-dosage yi-5-10ML rhoqo.

Kwaye samangaliswa kukuba, emva kokuyisebenzisa, safumanisa ukuba ayisebenzisi nje kuphela amanzi, kodwa igcina amanzi amaninzi.Xa kuhlanjwa ngesandla, ndandisoyika ukuba ayizukucoceka ngokwaneleyo ukuba ichaphazele iziphumo zovavanyo, ngoko ndandivula itephu ukuze ndihlanjwe ngamandla ibhotile, kwaye ininzi yayo yayiza kuhlanjwa, eyayiza kuchitha ngokwenene. amanzi amaninzi.Ngebhotileimeshini yovasa Impahla, ubungakanani bamanzi bunokulawulwa kuzo zonke ikhonkco, kwaye iindleko zamanzi zebhubhoratri ziphantsi kakhulu kunangaphambili.

Ngokwabelana ngabavavanyi bakhankanywe ngasentla, sinokubona ukuba umatshini wokuhlamba iibhotile awukwazi ukucoca kuphela izixhobo zovavanyo ngokukhawuleza nangcono, kodwa kunye nokugcina amanzi.Ikwenza njani oko?Makhe sibone inkqubo yokuhlamba ngezantsi ukuze siyiqonde.

Inkqubo yokuhlamba yelabhoratri yokutshiza umatshini wokuhlamba iibhotile ezizenzekelayo:

1. Ukucoca kwangaphambili: sebenzisa kuqala amanzi okupompoza kube kanye, kwaye usebenzise ingalo yokutshiza ukwenza i-high-pressure circular ukuhlamba kwisitya ukuze uhlambulule intsalela kwibhotile kunye nesitya, kwaye ukhuphe amanzi amdaka emva kokuhlamba.(Ielabhoratri ezinemiqathango zinokusebenzisa amanzi acocekileyo endaweni yamanzi etephu)

2. Ukucoca okuphambili: Faka amanzi okupompoza okwesibini, ukucoca ukufudumala (ukulungiswa kwiiyunithi ze-1 ° C, ukulungelelaniswa kwi-93 ° C), isixhobo songeza ngokuzenzekelayo i-agent yokucoca i-alkaline, kwaye iyaqhubeka nokuhlamba umjikelo ophezulu woxinzelelo. iibhotile kunye nezitya ngokusebenzisa ingalo yokutshiza , Khupha amanzi amdaka emva kokuhlamba.

3. I-Neutralization kunye nokucoca: Faka amanzi okupompoza okwesithathu, ubushushu bokucoca bu malunga ne-45 ° C, isixhobo songeza ngokuzenzekelayo i-agent yokucoca i-acidic, kwaye siyaqhubeka nokuhlambulula iibhotile kunye nezitya ngoxinzelelo oluphezulu ngengalo yokutshiza, kunye nokukhupha amanzi. amanzi amdaka emva kokuhlamba.

4. Ukucoca: Kukho amaxesha ama-3 okuhlanjululwa ewonke;

(1) Faka itephu yamanzi, khetha irensi yokufudumeza;

(2) Faka amanzi acwengileyo, khetha irensi yokufudumeza;

(3) Faka amanzi acwengileyo okuhlanjululwa, khetha irensi yokufudumeza;ubushushu bamanzi okuhlamba bunokusetwa kuma-93° C, ngokubanzi malunga nama-75°C kuyacetyiswa.

5. Ukomisa: Iibhotile ezihlanjululweyo zomiswe ngokukhawuleza kwaye zicoceke ngaphakathi nangaphandle kwesitya ngexesha lenkqubo yokufudumeza i-cyclic, i-steam blowing, i-condensation, kunye nokukhutshwa, ngelixa uphepha ukungcola okwesibini emva kokucoca.

Ngokuqinisekileyo, le nkqubo yokucoca ingentla yinkqubo nje yesiqhelo.Umatshini wokuhlamba unokhetha inkqubo yokucoca ngokweemfuno ezithile zezixhobo zebhubhoratri.Yonke inkqubo yezixhobo ihlanjululwa ngokuzenzekelayo, kwaye emva kokuba isixhobo siqale umsebenzi wokucoca, akukho basebenzi bafunekayo ukuba benze nayiphi na imisebenzi.

Ukushwankathela, umatshini wokuhlamba iibhotile ozenzekelayo kwilebhu ngokuqinisekileyo ungumncedi olungileyo kwilabhoratri yethu, yiyo loo nto uninzi lweelabhoratri ngoku zixhotyiswe ngezi zixhobo.
