Ua ib qho tseem ceeb ntawm cov organic intermediate thiab cov kuab tshuaj uas siv dav hauv kev lag luam tshuaj lom neeg, cyclohexanone feem ntau yog siv rau hauv kev lag luam xws li resin, txheej thiab tshuaj fiber. Vim nws cov yam ntxwv ntawm kev kub hnyiab, volatility thiab khaus, ntau cov lus nug feem ntau tshwm sim thaum lub sijhawm tsim khoom, khaws cia, thauj mus los thiab siv. Daim ntawv no txheeb xyuas cov lus nug hauv kev lag luam siab thiab muab cov lus teb tshaj lij raws li cov khoom siv lub cev thiab tshuaj lom neeg nrog rau cov lus qhia kev nyab xeeb, muab cov ntaub ntawv siv tau rau cov kws kho mob.
1. Cov Khoom Siv Lub Cev thiab Tshuaj Lom Zem ntawm Cyclohexanone
Cyclohexanone (CAS: 108-94-1) muaj cov mis molecular ntawm C₆H₁₀O. Nyob rau hauv qhov kub thiab txias ib txwm muaj, nws yog ib qho kua tsis muaj xim rau daj ntseg nrog ib qho tsw qab zib tshwj xeeb zoo li mint thiab camphor, uas yog khaus ntawm cov concentration siab. Nws muaj cov yam ntxwv ruaj khov ntawm lub cev thiab tshuaj lom neeg: lub ntsiab lus yaj ntawm -45 ° C, lub ntsiab lus kub ntawm 155.6 ° C, thiab qhov ceev ntawm 0.9478 g / cm³ ntawm 20 ° C. Vim tias sib dua dej, nws yuav ntab rau ntawm qhov dej yog tias muaj kev xau. Me ntsis soluble hauv dej, cyclohexanone yog sib xyaw nrog feem ntau cov organic solvents xws li ethanol, ether thiab benzene. Nrog lub khob kaw flash point ntawm 46 ° C, nws yog cais ua Class B flammable liquid. Nws cov pa tuaj yeem tsim cov khoom sib xyaw nrog huab cua, nrog rau qhov ntim tawg txwv ntawm 1.1% -9.4%. Nws yooj yim hlawv thiab tawg thaum raug rau cov nplaim taws qhib, kub heev thiab cov tshuaj oxidants muaj zog.
2. Cov Ntawv Thov Tseem Ceeb ntawm Cyclohexanone
Cyclohexanone yog ib qho khoom siv tseem ceeb hauv kev tsim tshuaj lom neeg zoo nrog ntau yam kev siv. Nws siv thawj zaug yog kev npaj cov caprolactam thiab adipic acid, uas tau ua tiav ntxiv los tsim nylon 6, nylon 66 thiab lwm yam khoom siv tshuaj fiber, ua rau nws yog ib qho tseem ceeb hauv kev lag luam textile thiab tshuaj fiber. Lub caij no, nws ua haujlwm ua cov kuab tshuaj ua haujlwm siab nrog kev yaj zoo rau cov ntaub ntawv polymer suav nrog polyurethane, epoxy resin thiab acrylic resin, thiab siv dav hauv kev tsim cov txheej, inks, nplaum thiab cov neeg sawv cev ua tiav tawv. Tsis tas li ntawd, nws tuaj yeem siv rau hauv kev npaj cov roj hmab antioxidants, cov organic synthesis auxiliaries thiab cov tshuaj intermediates, thiab feem ntau siv rau hauv kev ua yas thiab kev ntxuav hlau.
3. Kev phom sij ntawm Cyclohexanone rau Tib Neeg Kev Noj Qab Haus Huv
Cyclohexanone muaj tshuaj lom thiab ua rau khaus, thiab tuaj yeem nkag mus rau hauv tib neeg lub cev los ntawm kev ua pa, kev sib cuag ntawm daim tawv nqaij thiab kev noj. Kev raug cyclohexanone uas muaj cov tshuaj tsawg tsawg mus sij hawm ntev yuav ua rau khaus cov qhov muag, qhov ntswg thiab caj pas, ua rau muaj cov tsos mob xws li kua muag, hnoos thiab caj pas qhuav. Kev sib cuag ntawm daim tawv nqaij ntev yuav ua rau cov roj ntawm daim tawv nqaij puas tsuaj, ua rau qhuav, tawv nqaij tawv, tawg thiab mob dermatitis. Kev nqus cov pa roj uas muaj cov tshuaj ntau ntau yuav ua rau lub paj hlwb tsis ua haujlwm, ua rau muaj cov tsos mob xws li kiv taub hau, xeev siab, qaug zog thiab ntuav, thiab cov mob hnyav yuav ua rau tsis meej pem, hypothermia thiab tshee hnyo. Kev noj tsis raug yuav ua rau khaus txoj hnyuv thiab ua rau lub siab thiab lub raum ua haujlwm puas tsuaj. Hauv cov xwm txheej ua haujlwm, qhov siab tshaj plaws ntawm qhov chaw ua haujlwm raug tswj hwm ntawm 200 mg / m³.
4. Cov Qauv Txheem rau Cyclohexanone Cia thiab Kev Thauj Mus Los
Rau kev khaws cia, cyclohexanone yuav tsum khaws cia rau hauv lub tsev khaws tshuaj tshwj xeeb uas txias, qhuav thiab muaj cua nkag tau zoo, deb ntawm cov chaw hluav taws thiab cov chaw kub. Qhov kub ntawm lub tsev khaws khoom yuav tsum tsis pub tshaj 30 ° C, thiab tsis pub muaj hnub ci ncaj qha. Cov thawv yuav tsum kaw kom nruj kom tiv thaiv kev yaj thiab xau. Tsis pub sib xyaw nrog cov tshuaj oxidants, cov kua qaub muaj zog thiab cov hauv paus muaj zog. Lub tsev khaws khoom yuav tsum muaj teeb pom kev zoo uas tiv taus kev tawg, cov chaw cua nkag tau thiab cov tshuaj tua hluav taws. Rau kev thauj mus los, cyclohexanone yuav tsum xa raws li cov qauv rau cov kua dej phom sij uas yooj yim hlawv. Cov tsheb thauj mus los yuav tsum tuav daim ntawv pov thawj thauj mus los tshuaj lom neeg txaus ntshai thiab yuav tsum muaj cov khoom siv tiv thaiv hluav taws xob, cov khoom siv tua hluav taws thiab cov khoom siv tiv thaiv thaum muaj xwm txheej ceev. Thaum thauj mus los, yuav tsum tsis txhob raug tshav ntuj, kev sib tsoo hnyav thiab kev cuam tshuam. Tsis pub sib xyaw kev thauj mus los nrog zaub mov thiab cov tshuaj oxidants. Kev thauj khoom thiab tshem tawm yuav tsum tau ua tib zoo kom tiv thaiv kev xau.
5. Kev Kho Mob Thaum Muaj Xwm Ceev Rau Kev Xaus Cyclohexanone Thiab Kev Raug Mob Ntawm Tib Neeg
Yog tias raug daim tawv nqaij, tshem cov khaub ncaws uas muaj kuab lom tam sim ntawd thiab yaug daim tawv nqaij kom huv si nrog dej huv ntau li ntau tau tsawg kawg 15 feeb. Yog tias raug qhov muag, tuav lub qhov muag qhib thiab yaug lub qhov muag tas li nrog dej huv lossis cov ntsev ntsev ib txwm ua ntej nrhiav kev kho mob raws sijhawm. Yog tias ua pa tau, maj mam tsiv ntawm qhov chaw muaj kuab lom mus rau huab cua ntshiab. Muab kev pab oxygen rau cov neeg ua pa nyuaj, thiab ua pa dag tam sim ntawd kom tsis txhob ua pa ua ntej kho mob. Thaum muaj qhov xau, tshem tawm cov neeg ua haujlwm tsis tseem ceeb sai sai, cais thaj chaw xau thiab txiav txhua qhov chaw hluav taws kom tiv thaiv cov nplaim taws qhib thiab hluav taws xob static. Qhov xau me me tuaj yeem nqus tau nrog xuab zeb lossis cov pa roj carbon activated. Yog tias muaj qhov xau loj, tsim cov kwj dej kom kaw, sau cov kua xau kom rov qab tau lossis muab rau cov koom haum tshaj lij pov tseg. Txwv tsis pub tso ncaj qha rau hauv cov dej thiab cov kav dej phwj.
6. Kev Ceev Faj rau Kev Siv Cyclohexanone Txhua Hnub
Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshaj lij thiab ua raws li cov lus qhia ua haujlwm. Cov khoom siv tiv thaiv tus kheej xws li tsom iav, hnab looj tes roj hmab uas tiv taus cov kuab tshuaj thiab lub ntsej muag roj yuav tsum tau hnav thoob plaws hauv kev ua haujlwm. Qhov chaw ua haujlwm yuav tsum tswj kom muaj cua nkag mus rau hauv, thiab txwv tsis pub haus luam yeeb, noj mov thiab haus dej kom tshem tawm cov kev pheej hmoo hluav taws. Txhua yam khoom siv tsim khoom yuav tsum ua haujlwm hauv lub xeev kaw, thiab cov kav dej thiab cov qhov dej yuav tsum tau kuaj xyuas tsis tu ncua kom tiv thaiv kev xau. Tom qab ua haujlwm, cov neeg ua haujlwm yuav tsum ntxuav tes thiab lub ntsej muag kom huv si thiab hloov khaub ncaws ua haujlwm, thiab yuav tsum tsis txhob hnav khaub ncaws ua haujlwm uas muaj kuab tshuaj hauv thaj chaw nyob. Tsis tas li ntawd, yuav tsum teeb tsa cov cim ceeb toom hauv thaj chaw ua haujlwm, nruab nrog cov chaw ntxuav dej thaum muaj xwm txheej ceev thiab cov khoom siv tua hluav taws, thiab yuav tsum tau ua cov kev cob qhia thaum muaj xwm txheej ceev tsis tu ncua.
