Phenothiazine CAS 92-84-2 yog dab tsi?
Phenothiazine CAS 92-84-2 yog ib qho tshuaj tsw qab nrog cov tshuaj formula S (C6H4) 2NH.
Thaum rhuab thiab nyob rau hauv kev sib cuag nrog cov acids muaj zog, nws decomposes los tsim tshuaj lom thiab irritating pa luam yeeb uas muaj nitrogen oxides thiab sulfur oxides.
Kev nrawm nrawm nrog cov oxidants muaj zog tuaj yeem tsim kev pheej hmoo ntawm hluav taws kub.
Daim ntawv thov
1. Phenothiazine yog ib qho nruab nrab ntawm cov tshuaj zoo xws li tshuaj thiab dyes. Nws yog cov khoom siv hluavtaws ntxiv (polymerization inhibitor rau kev tsim cov vinylon), txiv hmab txiv ntoo tshuaj tua kab, thiab tshuaj tua tsiaj. Nws muaj cov txiaj ntsig tseem ceeb ntawm cov nyuj, yaj, thiab cov nees, xws li cov kab mob plab, kab mob nodule, lub qhov ncauj suppressor nematode, Chariotis nematode, thiab yaj lub caj dab zoo nematode.
2. Kuj hu ua thiodiphenylamine. Phenothiazine CAS 92-84-2 feem ntau yog siv los ua polymerization inhibitor rau acrylic ester-based ntau lawm. Nws kuj yog siv rau kev sib txuas ntawm cov tshuaj thiab dyes, nrog rau cov khoom siv ntxiv rau cov khoom siv hluavtaws (xws li polymerization inhibitors rau vinyl acetate thiab raw cov ntaub ntawv rau roj hmab anti-aging agents). Nws kuj yog siv los ua tshuaj tua kab rau cov tsiaj nyeg thiab ua tshuaj tua kab rau txiv hmab txiv ntoo.
3. Phenothiazine CAS 92-84-2 feem ntau yog siv los ua ib qho zoo heev polymerization inhibitor rau vinyl monomers thiab yog dav siv nyob rau hauv zus tau tej cov acrylic acid, acrylate, methacrylate, thiab vinyl acetate.
Cia tej yam kev mob
Cov khoom no yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw txias thiab qhuav.
Ntim rau hauv 25-kg hnab yas, woven hnab, los yog yas nruas. Khaws rau hauv qhov chaw txias, qhuav, thiab ventilated warehouse. nruj me ntsis tiv thaiv cov dej noo thiab dej, tiv thaiv tshav ntuj, thiab kom deb ntawm qhov hluav taws kub thiab cua sov. Lub teeb loading thiab unloading thaum lub sij hawm thauj mus los los tiv thaiv cov ntim puas.
Kev ruaj ntseg
1.Thaum khaws cia rau hauv huab cua ntev, nws yog oxidation thiab darkens nyob rau hauv cov xim, exhibiting sublimation zog. Muaj cov ntxhiab tsw tsw uas ua rau tawv nqaij. Flammable thaum raug cov nplaim taws qhib lossis kub kub.
2. Cov khoom siv tshuaj lom neeg, tshwj xeeb tshaj yog thaum cov khoom siv tsis tiav cov khoom siv nrog diphenylamine, kev noj tshuaj thiab kev nqus pa tuaj yeem ua rau muaj tshuaj lom. Cov khoom no tuaj yeem nqus tau los ntawm daim tawv nqaij, ua rau tawv nqaij ua xua, dermatitis, discoloration ntawm cov plaub hau thiab cov rau tes, o ntawm conjunctiva thiab cornea, nrog rau stimulating lub plab hnyuv ib ntsuj av, ua rau lub raum thiab daim siab, ua rau hemolytic anemia, mob plab, thiab tachycardia. Cov neeg ua haujlwm yuav tsum hnav cov khoom tiv thaiv. Cov neeg uas siv nws los ntawm qhov yuam kev yuav tsum tam sim ntawd ua rau plab hnyuv thiab tau txais kev kho mob.
