Tus Kws Kho Mob Txog Kev Phom Sij Ib Puag Ncig

I. Kev phom sij rau kev noj qab haus huv

Txoj Kev Nkag Mus: Kev Ua Pa, Kev Noj Haus, Kev Nqus Pa Percutaneous.

Kev phom sij rau kev noj qab haus huv: Zoo ib yam li aniline, tab sis tsis muaj zog dua aniline, tuaj yeem ua rau mob qog nqaij hlav thaum kov daim tawv nqaij. Kev nqus ua rau muaj methemoglobin thiab cyanosis. Xeev siab, kiv taub hau, mob taub hau thiab ntshav tuaj yeem tshwm sim tom qab kov.

Cov ntaub ntawv txog kev lom thiab kev coj cwj pwm ib puag ncig

Kev lom tshuaj lom: LD501410mg/kg (nas qhov ncauj); 1770mg/kg (luav percutaneous)

COV KHOOM TXOM NYEM: Yog tias muaj nplaim taws qhib, kub heev lossis kov cov neeg sawv cev oxidizing, muaj kev pheej hmoo ntawm kev kub hnyiab thiab tawg. Cov pa roj nitrogen oxide lom raug tso tawm los ntawm kev rhuav tshem cua sov.

Cov khoom siv hlawv (kev lwj): carbon monoxide, carbon dioxide, nitrogen oxides.

Kev saib xyuas txoj kev kho kom raug

Kev kho txoj kev pov tseg

Kev teb rau kev nchuav

Tshem cov neeg ua haujlwm tawm ntawm qhov chaw muaj kuab paug mus rau thaj chaw nyab xeeb, txwv tsis pub cov neeg ua haujlwm tsis muaj feem cuam tshuam nkag mus rau hauv thaj chaw muaj kuab paug, thiab txiav qhov chaw hluav taws. Nws raug pom zoo kom cov neeg teb thaum muaj xwm txheej ceev hnav cov khoom siv ua pa (SCBA) thiab cov khaub ncaws tiv thaiv tshuaj lom neeg. Tsis txhob kov ncaj qha rau qhov nchuav, thiab kaw qhov xau thaum ua kom muaj kev nyab xeeb. Kev txau dej yuav txo qhov evaporation, tab sis yuav tsis txo qhov kub hnyiab ntawm qhov nchuav hauv qhov chaw kaw. Nqus nrog cov xuab zeb lossis lwm yam tshuaj nqus dej uas tsis kub hnyiab thiab sau rau pov tseg ntawm qhov chaw pov tseg. Yog tias muaj cov nchuav loj, kev kaw siv cov ntug dej yuav raug siv, tom qab ntawd sau, hloov, rov ua dua tshiab, lossis pov tseg yam tsis muaj kev kho mob txaus ntshai.

Txoj kev pov tseg pov tseg: kev hlawv, lub tshuab hlawv nrog lub chamber tom qab hlawv, cov nitrogen oxides los ntawm lub tshuab hlawv los ntawm lub scrubber kom tshem tawm.

Kev tiv thaiv

Kev tiv thaiv kev ua pa: Hnav lub npog ntsej muag roj thaum muaj kev pheej hmoo ntawm kev raug cov pa roj. Hnav lub tshuab ua pa uas muaj peev xwm ua tau (SCBA) thaum muaj kev cawm neeg thaum muaj xwm txheej ceev lossis kev khiav tawm.

Kev tiv thaiv qhov muag: Hnav cov tsom iav tiv thaiv tshuaj lom neeg.

Khaub Ncaws Tiv Thaiv: Hnav cov khaub ncaws ua haujlwm tes tsho nruj thiab khau roj hmab ntev.

Kev tiv thaiv tes: Hnav cov hnab looj tes roj hmab.

Lwm yam: Tsis pub haus luam yeeb, noj mov thiab haus dej ntawm qhov chaw ua haujlwm. Hloov thiab ntxuav khaub ncaws ua haujlwm sai li sai tau. Tsis txhob haus cawv ua ntej lossis tom qab ua haujlwm, thiab siv dej sov los da dej. Saib xyuas cov tshuaj lom. Ua kev kuaj mob ua ntej ua haujlwm thiab tsis tu ncua.

Kev Ntsuas Kev Pab Thaum Muaj Xwm Ceev

Kev kov daim tawv nqaij: Tshem tawm cov khaub ncaws uas muaj kuab paug tam sim ntawd thiab yaug kom huv si nrog xab npum thiab dej. Ua tib zoo saib xyuas tes, taw thiab rau tes.

Kev Sib Chwv Qhov Muag: Tam sim ntawd tsa qhov muag thiab yaug nrog dej ntws lossis cov kua ntsev ntau ntau.

Kev ua pa: sai sai tshem tawm ntawm qhov chaw mus rau qhov chaw muaj cua ntshiab. Muab cov pa oxygen yog tias muaj kev ua pa nyuaj. Yog tias muaj kev ua pa tsis taus, ua kom lub cev rov qab muaj zog tam sim ntawd. Nrhiav kev kho mob.

Kev noj: yaug qhov ncauj, haus dej, ntxuav plab thiab tom qab ntawd muab cov thee activated charcoal noj kom raws plab yog tias noj tsis tau. Nrhiav kev kho mob.

Txoj kev tua hluav taws: dej pos huab, ua npuas dej, carbon dioxide, hmoov qhuav, xuab zeb.

Kev kho kom raug txoj kev tsim khoom

Nws yog tau los ntawm kev sib xyaw ntawm aniline thiab methanol nyob rau hauv qhov muaj sulfuric acid ntawm qhov kub thiab siab. Kev siv cov khoom siv raw: aniline 790kg / t, methanol 625kg / t, sulfuric acid 85kg / t. Kev sib xyaw ntawm aniline thiab trimethyl phosphate tuaj yeem npaj tau hauv chav kuaj.

Kev siv thiab kev ua haujlwm ntawm kev kho kom raug

Nws yog cov khoom siv tseem ceeb ntawm cov tshuaj tiv thaiv kev o thiab tshuaj analgesic "Mefenamic acid", thiab kuj tseem siv tau ua cov khoom siv nruab nrab ntawm cov xim pleev, tshuaj tua kab thiab lwm yam khoom siv tshuaj.

Kev yaj: Insoluble hauv dej, soluble hauv kua qaub, ethanol, ether, chloroform, carbon tetrachloride, benzene.

Siv Tseem Ceeb: Siv ua cov khoom nruab nrab ntawm cov xim pleev, siv rau hauv kev tsim cov vanillin, azo dyestuff, triphenylmethane dyestuff, kuj siv tau ua cov kuab tshuaj, stabilizer, analytical reagent, thiab lwm yam.

Daim Ntawv Thov: Feem ntau yog 10% tshuaj styrene, hu ua #2 accelerant. Feem ntau siv ua ke nrog 2 # tus neeg sawv cev kho (dibenzoyl peroxide). Nws yog ib qho kev kho kom zoo heev uas cov resin muaj ntau cov phenol dawb lossis qhov twg cov saw polyester molecular muaj cov qauv loj molecular branched. (piv txwv li rau vinyl ester resin kho, bisphenol A hom polyester resin kho, chlorinated bridge anhydride hom polyester resin, thiab lwm yam.)
