♦Ukubuyekezwa kwecala:

Muva nje, izindaba ezidumile ze-“High-Priced Claim for Bottle Washers” zivuse umbono womphakathi osabalele. Indaba imi kanje:

Umgezi wamabhodlela wesikhashana uNkk Zhou, owesifazane, uneminyaka engaphezu kwengu-40 ubudala. Waqashwa ngoMeyi isikhathi esingaphansi kwezinyanga ezimbalwa elabhorethri eliphethwe yi-ejensi yokuhlola yangaphandle enyakatho yeShayina. UNkk Zhou unesibopho sokuhlanza izinto zengilazi ezifana ne-test tube, i-pipette, i-beaker kanye nendebe yokulinganisa elabhorethri. Enqubweni yokuwasha, ngenxa yomonakalo wamakhemikhali osele ezingilazini, ubuso bakhe, izandla zakhe kanye nezinye izingxenye zomzimba zalimala kakhulu. Leli cala lamukelwe yiminyango efanele.

UNkk Zhou utshele abezindaba ukuthi uhlelo lokuphatha lwangaphakathi lwelebhu esanda kusungulwa aluzange luphelele, futhi akakatholi ukuqeqeshwa okwanele kwangaphambi komsebenzi. Ikakhulukazi ekwelapheni izinto ezisele zamakhemikhali ngemva kokuhlolwa, abaziswanga ngezinga lengozi lama-reagents, imishini yokuzivikela kanye nezindlela zokuzivikela.

Ngaphezu kwalokho, umthwalo womsebenzi wokuhlanza izitsha kule labhorethri unzima kakhulu phakathi nezinsuku, kuyilapho ukuhlanzeka kwezingilazi elabhorethri kuphakeme kakhulu. Kodwa-ke, umphumela wokuwasha ngezandla uvame ukwehluleka ukuhlangabezana nezindinganiso ezizimele zelabhorethri, ngakho-ke kufanele ngisebenze isikhathi esengeziwe ukuze ngisebenze kabusha. Leli phuzu lizoba yisikhalazo esihlukile emnyangweni wezabasebenzi wendawo.

UNkk Zhou, ngokuhlolwa kokulimala kwe-inductrial, ubonakale elahlekelwe yikhono lokusebenza eliyingxenye. Ngokusho kwalokhu, ngicela ilabhorethri ukuthi ikhokhele izindleko zezokwelapha, izindleko zomsebenzi ezilahlekile, izindleko zokuhamba, njll., isamba esingaphezu kwesigidi sama-yuan. Ukulandelwa kwecala kusathuthuka.

Eqinisweni, kunezinhlobo eziningi zama-chemical reagents elabhorethri ezizobangela amazinga ahlukene omonakalo emzimbeni womuntu. Uma ilabhorethri ingathathi izinyathelo ezifanele zokuqapha abasebenzi futhi inganaki ukuhlanzwa kwezitsha zelabhorethri, kungabangela imiphumela emibi njengokuzwela, ukukhubazeka kanye nomdlavuza kubasebenzi. Ngakho-ke, kubalulekile ngathi ukuba nokuqonda okuyisisekelo ngama-toxic reagents abasebenzi belabhorethri abavame ukuchayeka kuwo.

♦Ama-reagent anobuthi avamile emalabhorethri

I-Hydrochloric acid. Uketshezi olungabonakali olungenambala. Iphunga linamandla futhi linamandla. Izakhiwo ezibhubhisayo eziphakeme. Futhi i-hydrochloric acid egxilile (i-hydrochloric acid evuthayo) isakwazi ukuphazamisa inkungu ye-acid. Ingalimaza ngokungenakuguqulwa izitho zokuphefumula, amehlo, isikhumba kanye nomgudu wokugaya ukudla. Kungashiwo lokho ngezicubu zomuntu, kodwa futhi nokuvikela ukulimala kwe-hydrochloric acid ngesimo senkungu ye-acid. Ngaphezu kwalokho, lapho i-hydrochloric acid ixutshwa nama-oxidants (njenge-bleach sodium hypochlorite noma i-potassium permanganate), kukhiqizwa igesi ye-chlorine enobuthi.

I-Formaldehyde. Empilweni yansuku zonke, ngivame ukuzwa "ngobuthi be-formaldehyde" bangaphakathi. Kuphrojekthi yokuthola i-o-phenylphenol, i-formaldehyde yayisetshenziswa njenge-organic extract; Ivame ukusetshenziswa njengesigaba sokuhamba ekutholeni ukuhlangana kwe-chromatography ye-liquid esebenza kahle kakhulu. Ngaphezu kwalokho, ivame ukusetshenziswa lapho kuhlanzwa imithombo ye-ion nge-mass spectrometry. Into inomthelela wokukhubazeka ohlelweni lwezinzwa oluphakathi. Inomthelela okhethekile wokukhetha ku-optic nerve kanye ne-retina futhi ibangela izinguquko ze-pathological. Ingabangela i-metabolic acidosis.

I-chloroform (i-chloroform). Ivame ukuvuselela amehlo, umgudu wokuphefumula, isikhumba kanye nolwelwesi lwamafinyila emzimbeni womuntu. Njenge-carcinogen, i-chloroform iyingozi esibindini nasezinso. Gqoka amagilavu ​​​​nezibuko bese usebenza endaweni yokushisa.

(4) I-Acetic anhydride. Ekutholakaleni kwe-pentachlorophenol elebhu, i-acetic anhydride isetshenziswa njenge-reactant ephakathi. Le nto iyalimaza esikhumbeni, inobuthi obuphansi, futhi ihambisana nokudabuka okukhulu.

(5) I-Toluene. Elabhorethri yezikhungo zokuhlola ukudla nezidakamizwa, i-toluene isetshenziswa njengesithako semvelo sokuthola izinsalela zezibulala-zinambuzane. Ukuthintana isikhathi eside kungabangela i-neurasthenia syndrome, i-hepatomegaly, isikhumba esomile, i-chapped, i-dermatitis, njll. Ukugxila okuphezulu kwegesi kunomthelela wezidakamizwa ohlelweni lwezinzwa oluphakathi, futhi ukugxila okuphezulu kwesikhathi eside kokuhogela kwayo umusi kungabangela i-anemia enkulu, okuholela ezifweni zegazi.

（6) I-Formic acid: inobuthi obukhulu futhi ilimaza kakhulu izicubu ze-mucosal, umgudu wokuphefumula ophezulu, amehlo kanye nesikhumba. Ukuphefumula, ukugwinya kanye nokumuncwa kwesikhumba kungabangela umonakalo.

Ngaphezu kwalokho, ama-reagent afana ne-benzoic acid kanye ne-phenylethanol nawo aneziphazamiso ezibalulekile. Lapho umzimba womuntu uphefumula, ugwinya, ukumuncwa kwesikhumba kungabangela umonakalo ezingxenyeni zomzimba womuntu eziveziwe.

Ngenxa yalokhu, ama-reagents anobuthi elabhorethri akuzona zodwa ezibalwe ngenhla, ngakho-ke ukugcinwa nokusetshenziswa kwawo kufanele kulandele ngokuqinile imithethonqubo efanele. Ikakhulukazi, bonke abasebenzi belabhorethri, okuhlanganisa nabasebenzi bokuhlanza, kufanele babe nolwazi lokuzivikela nokuvikela abanye, futhi basebenzise umsebenzi oyisisekelo wokugqoka imishini yokuzivikela efana namagilavu ​​​​nezibuko.

Yiqiniso, akunzima ukuthola kulokhu ukuthi ukuhlanzwa kwemikhumbi yokuhlola ngesandla, ikakhulukazi lezo zitsha zeglasi ezine-reagent enobuthi, ngeke kusongela ukuphepha kwabasebenzi abafanele kuphela, kodwa futhi kuzokwandisa izindleko zelebhu, kubangele izingxabano ezifanele, futhi kulimaze ngisho nedumela kanye nesithombe selebhu. Okubaluleke kakhulu, ukunemba kwemiphumela yokuhlolwa ngeke kuqinisekiswe uma izitsha zeglasi zingahlangabezani nezindinganiso zokuhlanzeka. Lesi futhi yisona sizathu esiyisisekelo sokuthi kungani umshini wokuwasha ilabhu ozenzakalelayo kanye neminye imishini ithandwa kakhulu kuzo zonke izinhlobo zamalebhu.

♦Incwadi yesandla cukuthambekela VSUmshini wokuhlanza ingilazi welebhu

Isimo sokuhlanza ngesandla:

Izindleko zamanzi, ugesi kanye nabasebenzi zikhuphukile;

Izinto eziningi ezivimbelayo nezingalawuleki;

Kunomthelela omkhulu empilweni yomzimba neyengqondo yomzimba womuntu;

I-Hangzhou XUmshini wokuwasha izingilazi ze-PZ：

Ukuhlanzeka kuqinisekisiwe ；

Ukuhlanza okujwayelekile okuhlakaniphile, okulula ukusebenza;

Ukulandeleka kwedatha yenqubo ephelele ；

Londoloza ngempumelelo izinsiza zelebhu;

Ukuhlanza kuyisinyathelo esibalulekile sokwelashwa okungenangozi kwe-reagent enobuthi eseleyo. I-Dishwasher yeLab ayigcini nje ngokuvikela ukuphepha nempilo yabasebenzi bokuhlola ngezinga elikhulu, kodwa futhi ifinyelela injongo yokuhlanza kwayo okuthembekile. Ukuze kuzuze ilabhorethri isikhathi eside, kufanele kube kusenesikhathi ukuthola i-glassware washer ezenzakalelayo ngokuphelele!
