Intshayelelo
IMethyl Ethyl Ketone Peroxide (MEKP) yiperoxide yendalo. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-methapyruvate:
Umgangatho:
- Imbonakalo: Ayinabala ukuya kulwelo olumthubi
-Indawo edanyazayo: 7°C
Sebenzisa:
- Njengomqalisi: I-Methopyruvate isetyenziswa ngokubanzi njenge-organic peroxide initiator kwaye ingasetyenziselwa ukuqalisa ukuphendula kwe-polymerization kwiinkqubo ze-resin ezifana ne-polyester, i-polyethylene, i-polypropylene, njl.
- I-Bleach: I-Methylpyruvate ingasetyenziselwa ukwenza i-bleach pulp kunye nephepha ukwandisa ubumhlophe bayo.
- I-solvents: Ngokunyibilika kwayo okulungileyo, i-methylpyruvate isetyenziswe njenge-solvent, ngokukodwa ukuchithwa kwee-resin ezithile kunye neengubo.
Indlela:
Ukulungiswa kwe-methylpyruvate kunokufumaneka ngokuphendula kwe-sodium hydroperoxide okanye i-tert-butyl hydroxyperoxide kunye ne-acetone phantsi kweemeko ze-alkaline.
Ulwazi ngoKhuseleko:
- I-Methylpyruvate yi-peroxide ye-organic ene-oxidizing kakhulu kwaye iyaqhuma. Xa ugcina kunye nokuphatha, iinkqubo ezifanelekileyo zokusebenza zokhuseleko kufuneka ziqwalaselwe ngokuthe ngqo, kubandakanywa nokuphepha ukudibanisa nezinto ezinokutsha, ukuthintela ukunyuka kweqondo lokushisa, ukuphepha impembelelo kunye nokungqubuzana, njl.
- Ngexesha lokuthutha, ukupakishwa okufanelekileyo kunye namanyathelo okukhusela kufuneka kuthathwe ukuqinisekisa ukuba akuchaphazeli ukushisa, ukutshisa kunye neemeko zokuvuselela.
- Nxiba iiglavu zekhemikhali, izibuko kunye neegawuni ngexesha lokusetyenziswa, qinisekisa ukungena komoya kakuhle, kwaye ugweme ukuphefumla, ukudibana nolusu kunye namehlo.
- Xa kukho ukuvuza okanye ingozi, amanyathelo angxamisekileyo kufuneka athathwe ngokukhawuleza ukususa ukuvuza kunye nokulahla inkunkuma ngokufanelekileyo.
Xa usebenzisa i-methylpyruvate, imimiselo efanelekileyo kunye neenkqubo zokusebenza zokhuseleko kufuneka zithotyelwe ngokungqongqo ukuqinisekisa ukhuseleko lomntu kunye nokhuseleko lokusingqongileyo. Kubalulekile ukugcina, ukuphatha nokuphatha into ngokufanelekileyo.
