♦Uphononongo lwemeko:

Kutshanje, iindaba ze-blockbuster "zeBango eliXabiso eliPhezulu leeBottle Washers" zivuselele uluvo lwabantu ngokubanzi.Ibali limi ngolu hlobo lulandelayo:

Iwasha yeebhotile zexeshana uNksk Zhou, obhinqileyo, ungaphezu kweminyaka engama-40 ubudala.Waqeshwa ngoMeyi ixesha elingaphantsi kweenyanga ezimbalwa kwilebhu yombutho wesithathu wovavanyo kumantla eTshayina.UNksz Zhou unoxanduva lokucoca izixhobo zeglasi ezifana netyhubhu yokuvavanya, i-pipette, i-beaker kunye nekomityi yokulinganisa kwibhubhu.Kwinkqubo yokuhlamba, ngenxa yomonakalo oseleyo weekhemikhali kwi-glassware, ubuso bakhe, izandla kunye nezinye iindawo zomzimba zalimala kakhulu.Eli tyala lamkelwe ngamasebe achaphazelekayo.

UNksz Zhou uxelele amajelo eendaba ukuba inkqubo yokulawula yangaphakathi yelebhu esanda kusekwa ayizange igqibelele, kwaye akafumananga uqeqesho olwaneleyo lwangaphambili.Ngokukodwa kunyango lwezinto ezishiyekileyo zeekhemikhali emva kovavanyo, abazange baziswe ngeqondo lengozi ye-reagents, izixhobo zokukhusela kunye neendlela zokukhusela.

Ukongeza, umthwalo wokusebenza wezixhobo zokucoca kule labhoratri unzima kakhulu ngeentsuku zeveki, ngelixa ucoceko lweglasi kwilabhoratri luphezulu kakhulu.Nangona kunjalo, iziphumo zokuhlanjwa ngesandla zihlala zisilela ukuhlangabezana nemigangatho yelabhoratri, ngoko ke kufuneka ndisebenze ixesha elongezelelweyo ukuze ndiphinde ndisebenze.

UNkskz Zhou ngenxa yovavanyo lomonzakalo we-inductrial ubonakalise ukuphulukana nesakhono sokusebenza.Ngokwale nto, ndicela i-laboratory ukuba ihlawule iindleko zonyango, iindleko zomsebenzi ezilahlekileyo, iindleko zokuthutha, njl., isamba esingaphezu kwe-1 yezigidi ze-yuan. Ukulandelwa kwetyala kusavela.

Enyanisweni, zininzi ii-reagents zeekhemikhali kwilabhoratri eziya kubangela amanqanaba ahlukeneyo omonakalo kumzimba womntu.Ukuba i-laboratory ayithathi izilumkiso ezifanelekileyo kubasebenzi kwaye iyakutyeshela ukucocwa kwezixhobo zebhubhoratri, kunokubangela iziphumo ezibuhlungu ezifana nokuziva, ukukhubazeka kunye nomhlaza kubasebenzi. Ngoko ke, kuyimfuneko ukuba sibe nokuqonda okusisiseko kwee-reagents ezinobuthi ezinobuthi. abasebenzi baselabhoratri bahlala bevezwa.

♦Ii-reagents ezinetyhefu eziqhelekileyo kwiilabhoratri

Hydrochloric acid.Ulwelo olungenambala olucacileyo.Ivumba linamandla kwaye lihlaba.Iipropati eziphezulu ezonakalisayo.Kwaye i-hydrochloric acid egxininisiweyo (i-fuming hydrochloric acid) isenako ukutshabalalisa inkungu ye-asidi.Ingonakalisa ngokungenakulungiseka amalungu okuphefumla, amehlo, ulusu kunye nomgudu wesisu.Kunokuthiwa ukuba kwizicubu zomntu, kodwa kwakhona ukugada umonakalo we-hydrochloric acid ngendlela yenkungu ye-asidi.Ukongezelela, xa i-hydrochloric acid ixutywe kunye ne-oxidants (efana ne-bleach sodium hypochlorite okanye i-potassium permanganate), igesi ye-chlorine enetyhefu iyaveliswa.

I-formaldehydeKubomi bemihla ngemihla, ndihlala ndisiva malunga ne-"formaldehyde poisoning" yangaphakathi.Kwiprojekthi yokufumanisa i-o-phenylphenol, i-formaldehyde yayisetyenziswe njenge-extract organic;Ihlala isetyenziswa njengenqanaba elihambayo kwintsebenzo ephezulu yolwelo lwe-chromatography ukufumanisa ulungelelwaniso.Ukongezelela, isetyenziswa rhoqo xa ucoca imithombo ye-ion nge-mass spectrometry.I-substance ine-paralytic effect kwinkqubo ye-nervous central.Inempembelelo ekhethekileyo yokukhetha kwi-optic nerve kunye ne-retina kwaye ibangela utshintsho lwe-pathological.Inokubangela i-acidosis ye-metabolic.

I-Chloroform (i-chloroform).Ihlala ivuselela amehlo, i-respiratory tract, isikhumba kunye ne-mucous membrane yomzimba womntu. Njenge-carcinogen, i-chloroform ibulala isibindi kunye nezintso.Wear iiglavu kunye ne-goggles kwaye usebenze kwi-fume hood.

(4) I-acetic anhydride.Kwilabhoratri yokufumanisa i-pentachlorophenol, i-acetic anhydride isetyenziswa njenge-reactant ephakathi.I-substance i-corrosion esikhumbeni, i-toxicity ephantsi, kwaye ihamba kunye nokukrazula okukhulu.

(5) Itoluyini.Kwibhubhoratri yokutya kunye namaziko okuvavanya iziyobisi, i-toluene isetyenziswe njengesicatshulwa se-organic ukuze kuchongwe iintsalela ze-pesticide.Uqhagamshelwano lwexesha elide lunokubangela i-neurasthenia syndrome, i-hepatomegaly, isikhumba esomileyo, i-chapped, i-dermatitis, njl. Impembelelo ye-narcotic kwinkqubo ye-nervous central, kunye nexesha elide lokuxinwa okuphezulu kokuphefumla komphunga kunokubangela i-anemia enzima, ekhokelela kwizifo zegazi.

(6) I-asidi ye-Formic: ityhefu kakhulu kwaye yonakalise ngokugqithisileyo izicubu ze-mucosal, indlela yokuphefumula ephezulu, amehlo kunye nesikhumba.

Ukongezelela, ii-reagents ezifana ne-benzoic acid kunye ne-phenylethanol nazo zinee-irritants ezibalulekileyo.Xa umzimba womntu uphefumla, ukungenisa, ukuxutywa kwesikhumba kunokubangela umonakalo kumzimba womntu obonakalisiweyo.

Ngenxa yoku, ii-reagents zelabhoratri ezinetyhefu azikho zodwa ezidweliswe apha ngasentla, ngoko ke ukugcinwa kwazo kunye nokusetyenziswa kwazo kufuneka zilandele ngokungqongqo imimiselo efanelekileyo. abanye, kwaye baphumeze umsebenzi osisiseko wokunxiba izixhobo zokukhusela ezinjengeeglavu kunye nezibuko.

Kakade ke, akukho nzima ukufumanisa kule meko ukuba ukucocwa ngesandla kweenqanawa zovavanyo, ngakumbi ezo zikhongozeli zeglasi ezine-reagent enetyhefu, aziyi kusongela kuphela ukhuseleko lomzimba lwabasebenzi abafanelekileyo, kodwa nokunyusa iindleko zebhubhoratri, zibangele Iingxabano, kwaye zide zonakalise igama kunye nomfanekiso welabhoratri.Okubaluleke ngakumbi, ukuchaneka kweziphumo zovavanyo akuyi kuqinisekiswa ukuba i-glassware ayihambisani nemigangatho yokucoceka.Esi sizathu esisisiseko sokuba kutheni i-Lab Lab Washer kunye nezinye izixhobo zokusebenza zithandwa kakhulu kuzo zonke iintlobo zeebhubhoratri.
