♦Ukubuyekezwa kwecala:

Muva nje, izindaba ze-blockbuster "Zesimangalo Sentengo Ephezulu Sabawasha Amabhodlela" zivuse umbono womphakathi owandile.Indaba imi kanje:

Uwasha amabhodlela wesikhashana UNkk Zhou, owesifazane, uneminyaka engaphezu kuka-40 ubudala.Waqashwa ngoMeyi isikhathi esingaphansi kwezinyanga ezimbalwa elabhorethri ephethwe yinkampani yangaphandle ehlola abantu enyakatho neChina.UNkosikazi Zhou nguye obhekele ukuhlanzwa kwezinto zengilazi ezifana neshubhu lokuhlola, i-pipette, i-beaker kanye nenkomishi yokukala elabhorethri.Ngesikhathi egeza, ngenxa yokulimala kwamakhemikhali okusele ku-glassware, ubuso bakhe, izandla nezinye izingxenye zomzimba zalimala kabi.Leli cala lamukelwe yiminyango efanele.

UNkosikazi Zhou utshele intathelizindaba ukuthi indlela yokuphatha ngaphakathi kwelaboratory esanda kusungulwa kayizange iphelele, njalo kazange athole ukuqeqeshwa okwaneleyo engakaqali umsebenzi.Ikakhulukazi ekwelapheni izinto ezisele zamakhemikhali ngemva kokuhlolwa, abazange baziswe ngezinga lengozi lama-reagents, izinto zokuzivikela kanye nezindlela zokuzivikela.

Ngaphezu kwalokho, umsebenzi wezitsha zokuhlanza kule labhorethri unzima impela phakathi nezinsuku, kuyilapho ukuhlanzeka kwezingilazi elabhorethri kuphezulu kakhulu.Kodwa-ke, umphumela wokugeza izandla ngokuvamile uyehluleka ukuhlangabezana nezindinganiso ezizimele zelabhorethri, ngakho kufanele ngisebenze isikhathi esengeziwe ukuze ngisebenze kabusha. Leli phuzu lizoba isikhalazo esihlukile somnyango wezabasebenzi wendawo.

UNkosikazi Zhou ngenxa yokuhlolwa kokulimala kwe-inductrial ubonise ukuthi ulahlekelwe amandla okusebenza kancane.Ngokwalokhu, ngicela ilabhorethri ukuthi inxephezele izindleko zezokwelapha, izindleko zomsebenzi ezilahlekile, izindleko zokuhamba, njll., isamba esingaphezu kwama-yuan ayizigidi ezingu-1. Ukulandelela icala kusathuthuka.

Eqinisweni, kukhona ama-reagents amakhemikhali amaningi elabhorethri azodala amazinga ahlukene okulimala emzimbeni womuntu.Uma ilabhorethri ingathathi izinyathelo zokuphepha ezanele kubasebenzi futhi ingakunaki ukuhlanzwa kwezitsha zaselabhorethri, kungase kubangele imiphumela emibi njengokuzwela, ukukhubazeka kanye nomdlavuza kubasebenzi. izisebenzi zaselabhorethri zivame ukuchayeka.

♦Ama-reagents anobuthi ajwayelekile kuma-laboratories

I-Hydrochloric acid.Uketshezi olungenambala olubonisa ngale.Iphunga linamandla futhi liyahlaba.Izakhiwo eziphezulu ezonakalisayo.Futhi i-hydrochloric acid egxilile (i-fuming hydrochloric acid) isengavuthisa inkungu ye-asidi.Ingase ilimaze ngendlela engenakulungiseka izitho zokuphefumula, amehlo, isikhumba kanye nomgudu wamathumbu.Kungashiwo ukuthi ngezicubu zomuntu, kodwa futhi nokuqapha ukulimala kwe-hydrochloric acid ngesimo senkungu ye-asidi.Ngaphezu kwalokho, lapho i-hydrochloric acid ixutshwa nama-oxidants (njenge-bleach sodium hypochlorite noma i-potassium permanganate), kukhiqizwa igesi ye-chlorine enobuthi.

I-formaldehyde.Ekuphileni kwansuku zonke, ngivame ukuzwa mayelana "nobuthi be-formaldehyde".Kuphrojekthi yokuthola i-o-phenylphenol, i-formaldehyde isetshenziswe njenge-organic extract;Ivamise ukusetshenziswa njengesigaba seselula ekutholweni kokuhlobana kwe-liquid chromatography yokusebenza okuphezulu.Ngaphezu kwalokho, ivamise ukusetshenziswa lapho kuhlanzwa imithombo ye-ion nge-mass spectrometry.Le nto inomphumela okhubazekile ohlelweni lwezinzwa olumaphakathi.Inomphumela okhethekile wokukhetha ku-optic nerve kanye ne-retina futhi idala izinguquko ze-pathological.Ingabangela i-metabolic acidosis.

I-Chloroform (i-chloroform).Ngokuvamile ivuselela amehlo, umgudu wokuphefumula, isikhumba kanye nolwelwesi lwamafinyila lomzimba womuntu.Njenge-carcinogen, i-chloroform iyingozi esibindini nasezinso.Gqoka amagilavu ​​nezibuko futhi usebenze ku-fume hood.

(4) I-acetic anhydride.Ekutholeni kwe-pentachlorophenol elabhorethri, i-acetic anhydride isetshenziswa njenge-reactant emaphakathi.Lokhu kudla esikhumbeni, ubuthi obuphansi, futhi kuhambisana nokukhala okukhulu.

(5) I-Toluene.Elabhorethri yezikhungo zokuhlola ukudla nezidakamizwa, i-toluene isetshenziswa njengengxenye yezinto eziphilayo ukuze kutholwe izinsalela zezibulala-zinambuzane.Ukuxhumana isikhathi eside kungase kubangele i-neurasthenia syndrome, i-hepatomegaly, isikhumba esomile, i-chapped, i-dermatitis, njll.Ukugxila okuphezulu kwegesi kune- umphumela we-narcotic ohlelweni lwezinzwa olumaphakathi, kanye nokugcwala okuphezulu kwesikhathi eside kokuhogela kwawo umhwamuko kungabangela i-anemia enzima, okuholela ezifweni zegazi.

(6) I-Formic acid: inobuthi obuphezulu futhi ilimaza kakhulu izicubu ze-mucosal, umgudu wokuphefumula ophezulu, amehlo nesikhumba.Ukuhogela, ukumunca nokumunca isikhumba kungabangela umonakalo.

Ngaphezu kwalokho, ama-reagents afana ne-benzoic acid ne-phenylethanol nawo anokucasuka okuphawulekayo.Lapho umzimba womuntu uphefumula, ungenisa, ukumuncwa kwesikhumba kungabangela ukulimala emzimbeni womuntu izingxenye eziveziwe.

Ngenxa yalokhu, ama-reagents aselabhorethri anobuthi akuzona kuphela ezibalwe ngenhla, ngakho ukugcinwa nokusetshenziswa kwazo kufanele kulandele ngokuqinile imithethonqubo efanele.Ikakhulukazi, bonke abasebenzi baselabhorethri, kuhlanganise nabahlanzayo, kufanele babe nokuqwashisa ngokuzivikela nokuvikela abanye, futhi enze umsebenzi oyisisekelo wokugqoka izinto zokuzivikela ezifana namagilavu ​​nezibuko.

Yiqiniso, akunzima ukuthola kuleli cala ukuthi ukuhlanzwa ngesandla kwemikhumbi yokuhlola, ikakhulukazi lezo zitsha zeglasi ezine-reagent enobuthi, ngeke nje zisongele ukuphepha ngokomzimba kwabasebenzi abathintekayo, kodwa futhi kwandise izindleko zelabhorethri, kubangele izingxabano, futhi kulimaze isithunzi nesithombe selabhorethri.Okubaluleke nakakhulu, ukunemba kwemiphumela yokuhlolwa ngeke kuqinisekiswe uma i-glassware ingahlangabezani nezindinganiso zokuhlanzeka.Lesi futhi isizathu esiyisisekelo sokuthi kungani i-automatic Lab Washer kanye neminye imishini yemishini ithandwa kakhulu kuzo zonke izinhlobo zamalabhorethri.

♦Imanuwali cukuncika VSIwasha ingilazi yelabhorethri

Isimo sokuhlanza mathupha:

Izindleko zamanzi, ugesi kanye nezabasebenzi zinyukile;

Izinto eziningi ezivimbelayo nezingalawuleki;

Kunomthelela omkhulu empilweni engokomzimba neyengqondo yomzimba womuntu;

I-Hangzhou XIwasha ingilazi ye-PZ:

Inhlanzeko iqinisekisiwe;

Intelligent ejwayelekile yokuhlanza, kulula ukusebenza;

Inqubo ephelele yokulandelelwa kwedatha;

Ngempumelelo yonga izinsiza elabhorethri;

Ukuhlanza kuyisinyathelo esibalulekile sokwelashwa okungenangozi kwensalela enobuthi.Umshini wokuwasha izitsha welebhu awukwazi nje ukuvikela ukuphepha nempilo yabasebenzi abahlolwayo ngezinga elikhulu kakhulu, kodwa futhi ufeza injongo yokuhlanza kwawo okuthembekile.Ukuze uthole inzuzo yesikhathi eside yelabhorethri, kufanele kube kusenesikhathi ukuthola iwasha yengilazi ezenzakalelayo ngokuphelele!
