Nk'ikintu cy'ingenzi kiva mu bimera n'umusemburo ukoreshwa cyane mu nganda zikora imiti, cyclohexanone ikoreshwa cyane mu nganda nka resin, gusiga irangi n'imitako. Bitewe n'imiterere yayo yo gutwika, guhindagurika no gushyuha, ibibazo bitandukanye bikunze kuvuka mu gihe cyo kuyitunganya, kuyibika, kuyitwara no kuyikoresha. Iyi nyandiko ikemura ibibazo by'inganda zikunze kugaragara cyane kandi igatanga ibisubizo by'umwuga bishingiye ku miterere y'umubiri n'imiti ndetse n'ibipimo by'umutekano, itanga ibitekerezo by'ingirakamaro ku bakora akazi kayo.
1. Imiterere y'ibanze y'umubiri n'imiti ya Cyclohexanone
Cyclohexanone (CAS: 108-94-1) ifite formula ya molekile ya C₆H₁₀O. Mu bushyuhe busanzwe n'umuvuduko, ni amazi adafite ibara cyangwa umuhondo werurutse afite impumuro nziza isa na mint na camphor, itera ububabare ku rugero rwo hejuru. Ifite ibipimo by'umubiri n'ibinyabutabire bidahinduka: aho ishonga ya -45°C, aho ishyuha ya 155.6°C, n'ubucucike bwa 0.9478 g/cm³ kuri 20°C. Kubera ko yoroshye kurusha amazi, izareremba hejuru y'amazi mu gihe yavuyemo amazi. Iyo cyclohexanone ishongesha gato mu mazi, ishobora kuvangwa n'ibintu byinshi bishongesha nk'ethanol, ether na benzene. Iyo ifite aho ipfutse ya 46°C, ishyirwa mu cyiciro cya B cy'amazi ashobora gushya. Umwotsi wayo ushobora gukora uruvange rw'ibintu biturika hamwe n'umwuka, hamwe n'ingano y'iturika ya 1.1%–9.4%. Ikunze gushya no guturika iyo ihuye n'umuriro ufunguye, ubushyuhe bwinshi n'ibintu birwanya ogisijeni bikomeye.
2. Imikoreshereze y'ingenzi ya Cyclohexanone
Cyclohexanone ni igikoresho cy'ingenzi mu buhanga bw'imiti myiza kandi ikoreshwa mu buryo bwinshi. Ikoreshwa cyane ni ugutegura caprolactam na aside adipic, birushaho gutunganywa kugira ngo bikore nylon 6, nylon 66 n'ibindi bicuruzwa bya fibre, bigatuma iba ingenzi mu nganda z'imyenda n'imiti. Hagati aho, ikora nk'umusemburo w'inganda ukoze neza ufite ubushobozi bwo gushonga cyane ku bikoresho bya polymer birimo polyurethane, epoxy resin na acrylic resin, kandi ikoreshwa cyane mu gukora irangi, wino, kole n'ibikoresho byo kurangiza uruhu. Byongeye kandi, ishobora gukoreshwa mu gutegura antioxydants za rubber, auxiliaries organic synthesis na intermediates farumasi, kandi ikoreshwa cyane mu gutunganya pulasitiki no gusukura ibyuma.
3. Ingaruka za Cyclohexanone ku buzima bw'abantu
Cyclohexanone ni uburozi kandi irakaza, kandi ishobora kwinjira mu mubiri w'umuntu binyuze mu guhumeka umwuka, gukora ku ruhu no kunywa mu kanwa. Kumara igihe kirekire urwaye cyclohexanone idafite imbaraga nyinshi bizamura uturemangingo tw'amaso, izuru n'umuhogo, bigatera ibimenyetso nko gushwanyagurika, gukorora no kuma k'umuhogo. Kumara igihe kirekire urwaye uruhu byangiza urwego rw'amavuta y'uruhu, bigatera kuma, gushwanyagurika, gushwanyagurika no gushwanyagurika k'uruhu. Guhumeka umwuka mwinshi bibuza uturemangingo tw'imitsi, bigatera ibimenyetso byo kugabanya ububabare nko kuzerera, isesemi, umunaniro no kuruka, kandi indwara zikomeye zishobora gutera urujijo, ubushyuhe bukabije no gutitira. Kurya mu buryo butunguranye bizatera umujinya mu nzira y'igifu no kwangiza imikorere y'umwijima n'impyiko. Mu bihe by'akazi, urugero ntarengwa rwemewe rwemewe mu kazi rugenzurwa neza kuri 200 mg/m³.
4. Ibipimo ngenderwaho byo kubika no gutwara Cyclohexanone
Mu kubika, cyclohexanone igomba kubikwa mu bubiko bwihariye bw’ibinyabutabire burimo ubukonje, humutse kandi bufite umwuka mwiza, kure y’inkongi z’umuriro n’amasoko y’ubushyuhe. Ubushyuhe bw’ububiko ntibugomba kurenga 30°C, kandi izuba ry’izuba ntirigomba kurenza. Ibikoresho bigomba gufungwa neza kugira ngo hirindwe ko ibintu byahinduka cyangwa ngo bive. Kubika ibinyabutabire bivangwa na ogisijeni, aside ikomeye n’ibice bikomeye birabujijwe. Ububiko bugomba kuba bufite amatara adaturika, ibikoresho byo guhumeka n’ibikoresho byo kuzimya umuriro. Mu gutwara, cyclohexanone igomba kugezwaho hakurikijwe amahame agenga imiti ishobora kwangiza amazi. Ibinyabiziga bitwara abantu bigomba kuba bifite icyemezo cy’ubwikorezi bw’ibinyabutabire byangiza kandi bifite ibikoresho birwanya imihindagurikire y’ikirere, ibikoresho byo kuzimya inkongi n’ibikoresho byo kurinda ubutabazi bw’ibanze. Mu gihe cyo gutwara, kwirindwa izuba, gukubitana gukomeye no gukomeretsa ibintu bigomba kwirindwa. Kuvanga gutwara ibiryo n’ibinyabutabire bibujijwe. Ibikorwa byo gupakira no gupakurura ibintu bigomba gukorwa witonze kugira ngo hirindwe ko ibintu byava.
5. Ubuvuzi bwihutirwa ku bijyanye no kuva kwa Cyclohexanone no kwanduzwa n'abantu
Mu gihe habayeho ikibazo ku ruhu, hita ukuramo imyenda yanduye hanyuma woze neza uruhu rwanduye n'amazi meza menshi mu gihe cy'iminota 15. Ku bijyanye no kuzana amaso, fungura amaso kandi ukomeze koza amaso n'amazi meza cyangwa umunyu usanzwe mbere yo gushaka ubuvuzi ku gihe. Mu gihe habayeho guhumeka, hita uva aho hantu handuye ujye mu mwuka mwiza. Tanga ubufasha bwa ogisijeni ku bibazo byo guhumeka, kandi uhite uhumeka by'ubukorano kugira ngo uhagarike guhumeka mbere yo kuvurwa na muganga. Iyo habayeho kuzana amazi, hita wimura abakozi badafite aho bahuriye n'ikibazo, shyira ahantu hazana amazi kandi uce amasoko yose y'umuriro kugira ngo wirinde inkongi z'umuriro n'amashanyarazi adahindagurika. Kuzana amazi mu gace gato bishobora gushyirwamo umucanga cyangwa karubone. Ku bijyanye no kuzana amazi menshi, shyiramo imiyoboro yo kubika amazi, kusanya amazi yavuye kugira ngo agarurwe cyangwa uyashyire mu bigo by'inzobere kugira ngo bijugunywe. Kuzana amazi mu mazi no mu miyoboro y'amazi birabujijwe cyane.
6. Amabwiriza yo kwirinda gukoresha Cyclohexanone buri munsi
Abakora bagomba guhabwa amahugurwa y’umwuga no kubahiriza amabwiriza agenga imikorere. Ibikoresho byo kwirinda birimo indorerwamo, uturindantoki twa rubber tudashonga na gaze bigomba kwambarwa mu gihe cyose cy’igikorwa. Aho igikorwa kibera hagomba kuba hafite umwuka mwiza, kandi kunywa itabi, kurya no kunywa birabujijwe kugira ngo hakurweho ingaruka zishobora guterwa n’inkongi. Ibikoresho byose bikorerwa bigomba gukora mu buryo bufunze, kandi imiyoboro n’amabati bigomba gusuzumwa buri gihe kugira ngo hirindwe ko amazi ava. Nyuma y’igikorwa, abakora bagomba gukaraba intoki no mu maso neza kandi bagahindura imyenda y’akazi, kandi ntibagomba kwambara imyenda y’akazi yanduye ahantu ho gutura. Byongeye kandi, ibimenyetso byo kuburira bigomba gushyirwa mu gace kakorerwamo, bifite ibikoresho byo gusohora amazi mu buryo bwihutirwa n’ibikoresho byo kuzimya umuriro, kandi hagomba gukorwa imyitozo ihoraho y’ubutabazi.
