Tifaftiraha Khatarta Deegaanka

I. Khataraha caafimaadka

Waddada duulaanka: Neefsashada, nuugista, nuugista percutaneous.

Khataraha caafimaadka: Si la mid ah aniline, laakiin ka daciifsan aniline, waxay sababi kartaa nabar ku dhaca maqaarka. Nuugista waxay keentaa samaynta methemoglobin iyo cyanosis. Lalabbo, dawakhaad, madax-xanuun iyo saameyn dhiig ayaa dhici kara ka dib marka la taabto.

Xogta sunta ah iyo dhaqanka deegaanka

Sunta daran: LD501410mg/kg (afka afka ah); 1770mg/kg (bakayle dilaacsan)

HANTIDA KHATARTA AH: Haddii uu jiro olol furan, kulayl badan ama la taabto walxaha oksijiinta ah, waxaa jira khatar gubasho iyo qarax. Qiiqa nitrogen oksaydh ee sunta ah waxaa lagu sii daayaa kulaylka oo burbura.

Gubashada (qallafsanaanta) alaabta: carbon monoxide, carbon dioxide, nitrogen oxides.

Habka kormeerka tafatirka

Habka Chromatography ee Gaaska loogu talagalay Go'aaminta Walxaha halista ah ee Hawada (Daabacaadda Labaad), oo uu tafatiray Hang Shih-ping [2]

Habka qashin-qubka

Jawaabta daadanaya

Ka daadgureynta shaqaalaha aagga wasakhaysan, geyn meel nabdoon, ka mamnuuc shaqaalaha aan xidhiidhka lahayn inay soo galaan aagga wasakhaysan, goona isha dabka. Waxaa lagu talinayaa in ka jawaabayaasha degdega ahi ay xidhaan qalabka neefsashada ee iska leh (SCBA) iyo dharka ka hortagga kiimikada. Ha la xiriirin si toos ah daadatay, oo ku xir qulqulka adigoo hubinaya badbaadada. Ku buufida ceeryaamada biyaha waxay yaraynaysaa uumi-baxa, laakiin ma dhimi doonto ololka daadanaya ee meesha bannaan. Ku nuugo isku dar ciid ah ama sorbent kale oo aan ololi karin oo ururi si loogu tuuro goobta qashinka. Haddii daadad waaweyni ay daadato, haynta iyadoo la isticmaalayo berms ayaa la isticmaalaa, oo ay ku xigto ururinta, wareejinta, dib u warshadaynta, ama tuurista iyada oo aan la helin daaweyn khatar ah.

Habka qashin-qubka: gubi, gubi leh qolka gubashada, nitrogen oxides ee ka soo baxa gubi iyada oo la marayo qashinka si meesha looga saaro.

Tallaabooyinka ilaalinta

Ilaalinta Neefsashada: Xidho maaskaro gaas marka ay jirto khatar ah inuu soo gaadho uumiga. Xiro qalab neefsasho oo isku filan (SCBA) haddii ay dhacdo samatabbixin degdeg ah ama baxso.

Ilaalinta indhaha: xidho muraayadaha badbaadada kiimikada.

Dharka ilaalinta: Xidho guud ahaan gacmo adag iyo kabo caag ah oo dhaadheer.

Ilaalinta gacanta: Xidho galoofyada caagga ah.

Kuwo kale: Sigaarka, wax ku cunista iyo cabbitaanka si adag ayaa looga mamnuucay goobta shaqada. Si degdeg ah u beddel oo u dhaq dharka shaqada. Ha cabin khamriga ka hor ama ka dib shaqada, oo isticmaal biyo diirran si aad u qubeysato. La soco suntan In la sameeyo baaritaanno caafimaad oo xilliyeed ah oo shaqada ka hor ah.

Tallaabooyinka Gargaarka Degdegga ah

Taabashada maqaarka: Isla markiiba ka saar dharka wasakhaysan oo si fiican ugu raaci saabuun iyo biyo. U fiirso gacmaha, cagaha iyo cidiyaha.

Xiriirka Indhaha: Isla markiiba kor u qaad daboolka indhaha oo ku raaci biyo badan oo socda ama xal cusbo leh.

Neefsashada: si deg deg ah uga saar goobta una gudbi hawo cusub. Maamul ogsijiinta haddii dhibka neefsashada uu dhaco. Haddii neefsashadu xidhmo, isla markiiba dib u soo noolee. Raadi daryeel caafimaad.

Nuugista: luqluq, cab biyo, caloosha oo dareere ka dibna sii dhuxul afka laga qaato si ay u keento shuban haddii ay dhacdo in si shil ah loo nuugo. Raadi daryeel caafimaad.

Habka deminta dabka: biyaha ceeryaamo, xumbo, kaarboon dioxide, budada qalalan, ciid.

Habka wax soo saarka tafatirka

Waxaa lagu helaa falcelinta u dhaxaysa aniline iyo methanol iyadoo ay jirto sulfuric acid heerkulka sare iyo cadaadiska sare. Isticmaalka alaabta ceeriin: aniline 790kg/t, methanol 625kg/t, sulfuric acid 85kg/t. Dareen-celinta aniline iyo phosphate trimethyl waxaa lagu diyaarin karaa shaybaarka.

Shaqada oo isticmaal tafatirka

Waa alaabta ceeriin ee ugu weyn ee ka hortagga bararka iyo xanuunka xanuunka "Mefenamic acid", waxaana sidoo kale loo isticmaali karaa sida walxaha dhexdhexaadka ah ee dheeha, sunta cayayaanka iyo alaabada kale ee kiimikada.

Solubility: Biyo ku milmayn, ku milmay xal acid, ethanol, ether, chloroform, tetrachloride carbon, benzene.

Isticmaalka ugu muhiimsan: Waxaa loo istcimaalaa dhex dhexaadinta dheeha, loo isticmaalo soo saarista vanillin, azo dyestuff, triphenylmethane dyestuff, sidoo kale waxaa loo isticmaali karaa sida dareere, xasiliye, reagent gorfaynta, iwm.

Codsiga: Sida caadiga ah 10% xal styrene ah, oo loo yaqaan #2 dardargelinta. Badanaa waxaa lala isticmaalaa 2 # wakiilka daaweynta (dibenzoyl peroxide). Waa hab wax ku ool ah oo daaweyn ah halkaas oo resin ka kooban yahay xaddi badan oo phenol lacag la'aan ah ama halka silsiladda poliesterka molecular ka kooban tahay qaab dhismeed ballaaran oo laamo leh. (tusaale ahaan vinyl ester resin curing, bisphenol A Nooc polyester resin curing, koloriin ku jira buundada anhydride nooca polyester-ka, iwm.)

Habka wax soo saarka

wax ka beddel

Waxaa lagu helaa falcelinta u dhaxaysa aniline iyo methanol iyadoo ay jirto sulfuric acid heerkulka sare iyo cadaadiska sare. Isticmaalka alaabta ceeriin: aniline 790kg/t, methanol 625kg/t, sulfuric acid 85kg/t. Dareen-celinta aniline iyo phosphate trimethyl waxaa lagu diyaarin karaa shaybaarka.
