Ikhabhinethi yokugeleza kwe-Laminar, ebizwa nangokuthi i-clean bench, iyithuluzi elihlanzekile lendawo elisetshenziswa kabanzi ukuze kusebenze abasebenzi. Lingadala indawo yomoya ehlanzekile kakhulu yendawo. Lilungele ucwaningo lwesayensi, imithi, ezokwelapha kanye nezempilo, amathuluzi okukhanya kagesi kanye neminye imboni. Ikhabhinethi yokugeleza kwe-Laminar ingaxhunywa futhi emugqeni wokukhiqiza inhlanganisela ngezinzuzo zomsindo ophansi kanye nokuhamba. Liyithuluzi elihlanza umoya eliguquguqukayo kakhulu elihlinzeka ngendawo yokusebenza ehlanzekile kakhulu yendawo. Ukusetshenziswa kwalo kunomthelela omuhle ekuthuthukiseni izimo zenqubo, ukuthuthukisa ikhwalithi yomkhiqizo kanye nokwandisa isivuno.
Izinzuzo zebhentshi elihlanzekile ukuthi kulula ukulisebenzisa, likhululekile, lisebenza kahle, futhi linesikhathi esifushane sokulungiselela. Lingasetshenziswa ngemizuzu engaphezu kweyi-10 ngemva kokuqala, futhi lingasetshenziswa nganoma yisiphi isikhathi. Ekukhiqizeni okuhlanzekile kwe-workshop, lapho umsebenzi wokugoma umningi kakhulu futhi ukugoma kudingeka kwenziwe njalo futhi isikhathi eside, ibhentshi elihlanzekile liyimishini efanelekile.
Ibhentshi elihlanzekile lisebenza ngenjini enezigaba ezintathu enamandla angaba ngu-145 kuya ku-260W. Umoya upheshulwa "ngesihlungi esikhulu" esakhiwe ngezingqimba zamashidi epulasitiki enziwe nge-microporous foam ukuze kwakheke indawo eqhubekayo engenalo uthuli. Umoya ohlanzekile ogeleza nge-laminar, okubizwa ngokuthi "umoya okhethekile osebenzayo", ususa uthuli, isikhunta kanye nezinhlamvu zamagciwane ezingaphezu kuka-0.3μm, njll.
Izinga lokugeleza komoya lebhentshi lokusebenzela elihlanzekile kakhulu lingu-24-30m/min, okwanele ukuvimbela ukungcola okubangelwa ukuphazamiseka okungenzeka okuvela emoyeni oseduze. Leli zinga lokugeleza ngeke livimbele ukusetshenziswa kwezibani zotshwala noma izitofu ze-bunsen ukushisa nokubulala amagciwane.
Abasebenzi basebenza ngaphansi kwezimo ezinjalo ezingezona ezokubulala amagciwane ukuze bavikele izinto ezihlanzekile ekungcoleni ngesikhathi sokudluliselwa kanye nokugonywa. Kodwa uma kwenzeka ugesi uphela phakathi nokusebenza, izinto ezivezwe emoyeni ongahlungiwe ngeke zivikeleke ekungcoleni.
Ngalesi sikhathi, umsebenzi kufanele uqedwe ngokushesha futhi kufanele kwenziwe uphawu ebhodleleni. Uma izinto ezingaphakathi zisesigabeni sokukhula, ngeke zisasetshenziswa ekukhuleni futhi zizodluliselwa ekukhuleni kwezimpande. Uma kuyizinto ezikhiqizwayo ezivamile, zingalahlwa uma ziningi kakhulu. Uma sezimile izimpande, zingagcinwa ukuze zitshalwe kamuva.
Ukunikezwa kwamandla kwamabhentshi ahlanzekile kusebenzisa kakhulu izintambo ezine ezinezigaba ezintathu, lapho kukhona intambo engathathi hlangothi, exhunywe egobolondweni lomshini futhi kufanele ixhunywe ngokuqinile entanjeni yomhlabathi. Ezinye izintambo ezintathu zonke ziyizintambo zesigaba, kanti i-voltage yokusebenza ingu-380V. Kukhona ukulandelana okuthile kusekethe yokufinyelela yezintambo ezintathu. Uma iziphetho zezintambo zixhunywe ngendlela engafanele, ifeni izobuyela emuva, futhi umsindo uzoba ojwayelekile noma ongavamile kancane. Akukho moya phambi kwebhentshi elihlanzekile (ungasebenzisa ilangabi lesibani sotshwala ukuze ubone ukunyakaza, futhi akukhuthazwa ukuhlola isikhathi eside). Nquma ukunikezwa kwamandla ngesikhathi, bese ushintshanisa izikhundla zanoma yiziphi izintambo ezimbili zesigaba bese uzixhuma futhi, futhi inkinga ingaxazululwa.
Uma kuxhunywe izigaba ezimbili kuphela zomugqa wezigaba ezintathu, noma uma esinye sezigaba ezintathu sinokuxhumana okungekuhle, umshini uzozwakala ungajwayelekile. Kufanele unqamule ngokushesha ugesi bese uwuhlola ngokucophelela, ngaphandle kwalokho injini izoshiswa. Lokhu kuqonda okujwayelekile kufanele kuchazwe ngokucacile kubasebenzi lapho beqala ukusebenzisa ibhentshi elihlanzekile ukuze bagweme izingozi nokulahlekelwa.
Ukungena komoya kwebhentshi elihlanzekile kungemuva noma ngaphansi kwangaphambili. Kukhona ishidi lepulasitiki elijwayelekile le-foam noma indwangu engalukiwe ngaphakathi kwesembozo sensimbi ukuze kuvinjwe izinhlayiya ezinkulu zothuli. Kufanele ihlolwe njalo, ihlukaniswe futhi igezwe. Uma ipulasitiki ye-foam isigugile, yishintshe ngesikhathi.
Ngaphandle kwendawo yokungena komoya, uma kunezimbobo zokuvuza komoya, kufanele zivinjwe kahle, njengokufaka iteyipu, ukugcwaliswa kukakotini, ukufaka iphepha leglue, njll. Ngaphakathi kwesembozo sensimbi esingaphambili kwebhentshi lokusebenzela kukhona isihlungi esikhulu. Isihlungi esikhulu singashintshwa futhi. Uma sesisetshenziswe isikhathi eside, izinhlayiya zothuli ziyavinjwa, isivinini somoya siyancishiswa, futhi ukusebenza okuhlanzekile akunakuqinisekiswa, singashintshwa ngesisha.
Impilo yesevisi yebhentshi elihlanzekile ihlobene nokuhlanzeka komoya. Ezindaweni ezinesimo sezulu esipholile, amabhentshi ahlanzekile kakhulu angasetshenziswa emalabhorethri ajwayelekile. Kodwa-ke, ezindaweni ezishisayo noma ezishisayo, lapho umkhathi uqukethe khona amazinga aphezulu empova noma uthuli, ibhentshi elihlanzekile kufanele libekwe ngaphakathi endlini eneminyango emibili. . Akumelwe nanini ngaphansi kwanoma yiziphi izimo i-air inlet hood yebhentshi elihlanzekile ibhekane nomnyango ovulekile noma ifasitela ukugwema ukuthinta impilo yesevisi yesihlungi.
Igumbi elihlanzekile kufanele lifuthwe njalo ngo-70% utshwala noma i-phenol engu-0.5% ukunciphisa uthuli nokubulala amagciwane, lisule amatafula nezitsha nge-2% neogerazine (u-70% utshwala nawo uyamukeleka), bese usebenzisa i-formalin (40% formaldehyde) kanye nenani elincane le-permanganic acid. I-Potassium ivalwa njalo futhi ifuthwe nge-fumigation, kuhlanganiswe nezindlela zokubulala amagciwane kanye nokubulala amagciwane njengezibani zokubulala amagciwane ze-ultraviolet (zivulwa imizuzu engaphezu kwengu-15 isikhathi ngasinye), ukuze igumbi elihlanzekile lihlale ligcina izinga eliphezulu lokubulala amagciwane.
Ingaphakathi lebhokisi lokugoma kufanele futhi lifakwe isibani se-ultraviolet. Vula isibani imizuzu engaphezu kwengu-15 ngaphambi kokusebenzisa ukuze ukhanyise futhi uhlanze amagciwane. Kodwa-ke, noma iyiphi indawo engenakukhanyiselwa imisebe isagcwele amagciwane.
Uma isibani se-ultraviolet sivuliwe isikhathi eside, singashukumisa ama-molecule e-oxygen emoyeni ukuthi ahlangane abe ama-molecule e-ozone. Le gesi inomphumela oqinile wokubulala amagciwane futhi ingakhiqiza umphumela wokubulala amagciwane emakhoneni angakhanyiswa ngqo yimisebe ye-ultraviolet. Njengoba i-ozone iyingozi empilweni, kufanele ucime isibani se-ultraviolet ngaphambi kokungena emsebenzini, futhi ungangena ngemva kwemizuzu engaphezu kweyishumi.
