Taw qhia
Methyl Ethyl Ketone Peroxide (MEKP) yog cov organic peroxide. Cov hauv qab no yog cov lus qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm methapyruvate:
Zoo:
- Cov tsos mob: tsis muaj xim rau cov kua daj daj daj
- Flash Point: 7 ° C
Siv:
- Raws li tus neeg pib: Methopyruvate tau dav siv los ua cov organic peroxide pib thiab tuaj yeem siv los pib cov tshuaj tiv thaiv polymerization hauv cov tshuab cob xws li polyester, polyethylene, polypropylene, thiab lwm yam.
- Bleach: Methylpyruvate tuaj yeem siv los ntxuav cov tawv nqaij thiab daim ntawv txhawm rau txhim kho nws cov xim dawb.
- Cov kuab tshuaj: Nrog nws cov solubility zoo, methylpyruvate yog siv los ua cov kuab tshuaj, tshwj xeeb tshaj yog rau kev sib cais ntawm qee cov resins thiab coatings.
Txoj kev:
Kev npaj ntawm methylpyruvate tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm sodium hydroperoxide lossis tert-butyl hydroxyperoxide nrog acetone nyob rau hauv cov xwm txheej alkaline.
Cov ntaub ntawv kev nyab xeeb:
- Methylpyruvate yog cov organic peroxide uas yog oxidizing thiab tawg. Thaum khaws cia thiab tuav, cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm yuav tsum tau ua nruj me ntsis, suav nrog kev zam kev sib cuag nrog cov khoom sib txuas, tiv thaiv qhov kub thiab txias, tsis txhob cuam tshuam thiab kev sib txhuam, thiab lwm yam.
- Thaum lub sij hawm kev thauj mus los, kev ntim khoom tsim nyog thiab kev tiv thaiv yuav tsum tau ua kom ntseeg tau tias nws tsis cuam tshuam los ntawm cua sov, ignition thiab excitation tej yam kev mob.
- Hnav cov hnab looj tes tshuaj, tsom iav thiab hnav khaub ncaws thaum siv, ua kom qhov cua zoo, thiab tsis txhob nqus pa, tiv thaiv daim tawv nqaij thiab qhov muag.
-Thaum muaj kev sib tsoo los yog kev sib tsoo, kev ntsuas kub ceev yuav tsum tau ua tam sim kom tshem tawm cov dej ntws tawm thiab pov tseg cov khoom pov tseg kom zoo.
Thaum siv methylpyruvate, cov kev cai cuam tshuam thiab cov txheej txheem kev nyab xeeb yuav tsum tau ua raws li nruj me ntsis kom ntseeg tau tus kheej kev nyab xeeb thiab ib puag ncig kev nyab xeeb. Nws yog ib qho tseem ceeb rau khaws cia, tuav thiab tuav cov khoom kom zoo.
