Njenge-organic intermediate ebalulekileyo kunye nesinyibilikisi esisetyenziswa kakhulu kwishishini leekhemikhali, i-cyclohexanone isetyenziswa kakhulu kwimizi-mveliso efana ne-resin, i-coating kunye ne-chemical fiber. Ngenxa yeempawu zayo zokutsha, ukuguquguquka kunye nokucaphuka, imibuzo eyahlukeneyo ihlala iphakama ngexesha lokuveliswa kwayo, ukugcinwa kwayo, ukuthuthwa kwayo kunye nokusetyenziswa kwayo. Eli phepha lihlalutya imibuzo yeshishini esetyenziswa rhoqo kwaye linika iimpendulo zobungcali ngokusekelwe kwiimpawu zomzimba nezekhemikhali kunye neenkcukacha zokhuseleko, linikezela ngeereferensi ezisebenzayo kubasebenzi abafanelekileyo.
1. Iimpawu ezisisiseko zomzimba nezekhemikhali zeCyclohexanone
I-Cyclohexanone (CAS: 108-94-1) inefomula yemolekyuli ye-C₆H₁₀O. Phantsi kobushushu obuqhelekileyo kunye noxinzelelo, lulwelo olungenambala ukuya kolutyheli olukhanyayo olunevumba elimnandi elikhethekileyo elifana ne-mint kunye ne-camphor, elicaphukisayo xa liphezulu. Inemilinganiselo yomzimba neyekhemikhali ezinzileyo: indawo yokunyibilika ye--45°C, indawo yokubila ye-155.6°C, kunye noxinano lwe-0.9478 g/cm³ kwi-20°C. Njengoko ilula kunamanzi, iya kudada phezu kwamanzi xa kuvuza. Inyibilika kancinci emanzini, i-cyclohexanone ixutywa nezinye izinyibilikisi zendalo ezifana ne-ethanol, i-ether kunye ne-benzene. Nge-flashpoint yekomityi evaliweyo ye-46°C, ihlelwa njengolwelo oluvuthayo lweClass B. Umphunga wayo unokwenza imixube eqhumayo nomoya, kunye nomda wokuqhuma we-1.1%–9.4%. Inokutsha kakhulu kwaye iqhume xa ibekwe kumalangatye avulekileyo, amaqondo obushushu aphezulu kunye nee-oxidants ezinamandla.
2. Usetyenziso oluPhambili lweCyclohexanone
I-Cyclohexanone sisixhobo esiphambili kubunjineli beekhemikhali ezintle kunye neemeko ezininzi zokusetyenziswa. Ukusetyenziswa kwayo okuphambili kukulungiselela i-caprolactam kunye ne-adipic acid, eziqhubekeka zicutshungulwa ukuvelisa i-nylon 6, i-nylon 66 kunye nezinye iimveliso zefayibha yeekhemikhali, nto leyo eyenza ukuba ibe yindawo ephambili kwishishini leefayibha zeekhemikhali kunye nelaphu. Okwangoku, isebenza njengesinyibilikisi semizi-mveliso esisebenza kakuhle esinokunyibilika ngamandla kwizixhobo zepolymer kubandakanya i-polyurethane, i-epoxy resin kunye ne-acrylic resin, kwaye isetyenziswa kakhulu kwimveliso yeengubo, ii-inki, izincamathelisi kunye neearhente zokugqiba isikhumba. Ukongeza, ingasetyenziswa ekulungiseleleni ii-antioxidants zerabha, izincedisi ze-organic synthesis kunye nezixhasi ze-pharmaceutical, kwaye isetyenziswa rhoqo ekucutshungulweni kweplastiki kunye nokucoca isinyithi.
3. Iingozi zeCyclohexanone kwiMpilo yoLuntu
I-Cyclohexanone inetyhefu kwaye iyacaphukisa, kwaye inokungena emzimbeni womntu ngokuphefumla, ukudibana nolusu kunye nokuginywa ngomlomo. Ukuvezwa ixesha elide kwi-cyclohexanone exineneyo kuya kucaphukisa i-mucous membranes yamehlo, impumlo kunye nomphimbo, okubangela iimpawu ezifana nokukrazula, ukukhohlela kunye nomphimbo owomileyo. Ukudibana nolusu ixesha elide kuya konakalisa umaleko weoyile yolusu, okukhokelela ekomeni, ekuqhekekeni, ekuqhekekeni nasekudibaneni kwe-dermatitis. Ukuphefumla umphunga oxineneyo kakhulu kuthintela inkqubo ye-nervous ephakathi, okubangela iimpawu zokudambisa iintlungu ezifana nesiyezi, isicaphucaphu, ukudinwa kunye nokuhlanza, kwaye iimeko ezinzima zinokubandakanya ukudideka, i-hypothermia kunye nokungcangcazela. Ukuginywa ngengozi kuya kucaphukisa indlela yesisu kwaye konakalise imisebenzi yesibindi kunye nezintso. Kwiimeko zomsebenzi, uxinaniso oluphezulu oluvumelekileyo kwindawo yokusebenza lulawulwa ngokungqongqo kwi-200 mg/m³.
4. Iinkcukacha ezisemgangathweni zokugcina kunye nokuthuthwa kweCyclohexanone
Ukugcina, i-cyclohexanone mayigcinwe kwindawo yokugcina iikhemikhali ekhethekileyo epholileyo, eyomileyo nengenisa umoya kakuhle, kude nemithombo yomlilo kunye nemithombo yobushushu. Ubushushu bendawo yokugcina izinto akufuneki budlule kwi-30°C, kwaye ukukhanya kwelanga ngqo akuvumelekanga. Izikhongozeli mazivalwe ngokuqinileyo ukuthintela ukuguquguquka nokuvuza. Ukudibanisa indawo yokugcina nee-oxidants, ii-asidi ezinamandla kunye neziseko ezinamandla akuvumelekanga. Indawo yokugcina izinto mayixhotyiswe ngezibane ezingaqhumiyo, izixhobo zokungenisa umoya kunye nezicimi-mlilo. Ukuthutha, i-cyclohexanone mayiziswe ngokuhambelana nemigangatho yeekhemikhali ezinobungozi zolwelo ezinokutsha. Izithuthi zothutho mazibe neziqinisekiso ezifanelekileyo zokuthutha iikhemikhali ezinobungozi kwaye zixhotyiswe ngezixhobo ezichasene ne-static, izixhobo zokulwa nomlilo kunye nezinto zokukhusela ezingxamisekileyo. Ngexesha lokuthuthwa, ukuvezwa elangeni, ukungqubana okukhulu kunye nempembelelo kuya kuthintelwa. Ukudibanisa ukuthuthwa nokutya kunye nee-oxidants akuvumelekanga. Imisebenzi yokulayisha nokukhulula izinto kufuneka iphathwe ngobunono ukuthintela ukuvuza.
5. Unyango olungxamisekileyo lokuvuza kweCyclohexanone kunye nokuchaphazeleka kwabantu
Ukuba ulusu luthe lwadibana, susa impahla engcolileyo ngoko nangoko uze uhlambe ulusu oluchaphazelekayo kakuhle ngamanzi acocekileyo aneleyo ubuncinane imizuzu eli-15. Ukuba udibana namehlo, bamba iinkophe zivuleke kwaye uhlambe amehlo rhoqo ngamanzi acocekileyo okanye ityuwa eqhelekileyo ngaphambi kokuba ufune unyango ngexesha elifanelekileyo. Ukuba uphefumla, suka kwindawo engcolileyo ngokukhawuleza uye emoyeni omtsha. Nika uncedo lweoksijini kwiingxaki zokuphefumla, kwaye wenze ukuphefumla okwenziweyo ngoko nangoko ukuze uphephe ukuphefumla ngaphambi kokuba unyango luqale. Nje ukuba kubekho ukuvuza, khupha abasebenzi abangafanelekanga ngokukhawuleza, yahlula indawo evuzayo kwaye unqumle yonke imithombo yomlilo ukuthintela amalangatye avulekileyo kunye nombane ongashukumiyo. Ukuvuza kwindawo encinci kunokufunxwa yisanti okanye i-activated carbon. Ukuba ukuvuza okukhulu kukuvuza, yakha iidike zokuthintela, qokelela ulwelo oluvuzayo ukuze lubuyiselwe okanye ulunike amaziko obuchwephesha ukuze alahlwe. Ukukhupha ngokuthe ngqo emanzini nakwimijelo yamanzi amdaka akuvumelekanga ngokungqongqo.
6. Amanyathelo okuzikhusela xa usebenzisa i-Cyclohexanone yonke imihla
Abaqhubi kufuneka bafumane uqeqesho lobungcali kwaye balandele ngokungqongqo imigaqo yokusebenza. Izixhobo zokuzikhusela zomntu siqu kuquka iiglasi zokukhusela, iiglavu zerabha ezinganyibilikiyo kunye neemaski zegesi kufuneka zinxitywe kulo lonke ixesha lokusebenza. Indawo yokusebenza mayigcine umoya ungena ngokupheleleyo, kwaye ukutshaya, ukutya nokusela akuvumelekanga ukuphelisa iingozi zomlilo. Zonke izixhobo zemveliso mazisebenze zivaliwe, kwaye imibhobho kunye neevalvu mazihlolwe rhoqo ukuthintela ukuvuza. Emva komsebenzi, abaqhubi mabahlambe izandla kunye nobuso kakuhle kwaye batshintshe iimpahla zokusebenza, kwaye abafanele banxibe iimpahla zokusebenza ezingcolileyo kwiindawo zokuhlala. Ukongeza, imiqondiso yesilumkiso mayibekwe kwindawo yokusebenza, ixhotyiswe ngezixhobo zokuhlamba ngexesha likaxakeka kunye nezixhobo zokucima umlilo, kwaye kufuneka kwenziwe uqeqesho olungxamisekileyo rhoqo.
