Tshuaj Tshuaj Muaj Zog:

Methyl Ketone yog cov organic sib xyaw nrog cov tshuaj tov ch3coch3 thiab qhov hnyav molecular ntawm 72.11. Nws yog cov kua tsis muaj xim thiab pob tshab nrog cov ntxhiab tsw zoo sib xws rau acetone. Yooj yim volatile. Nws yog me ntsis nrog Ethanol, ether, benzene, chloroform thiab roj. Soluble hauv 4 seem ntawm cov dej, tab sis cov solubility txo thaum qhov kub nce ntxiv, thiab tuaj yeem tsim lub qhov dej sib xyaw. Tsawg toxicity, LD50 (RAT, qhov ncauj) 3300mg / kg. Cov nplaim, vapor tuaj yeem tsim cov sib xyaw tawg nrog cua. Kev siab ntawm vapor muaj cov khoom anesthetic.

Daim Ntawv Thov:

Methyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) yog ib qho muaj kuab lom, uas muaj nyob hauv ntau daim ntawv thov. Nws yog siv rau hauv cov khoom lag luam thiab cov khoom lag luam raws li cov kuab tshuaj rau cov nplaum, xim, thiab cov kuab tshuaj tua kab mob thiab ua cov kuab tshuaj tua kab. Ib lub ntuj tivthaiv ntawm qee cov zaub mov, methyl ketyl Ketone tuaj yeem tso tawm rau hauv ib puag ncig ntawm cov khoom siv hluav taws xob thiab cov kuab tshuaj zoo nkauj, raws li cov kuab tshuaj, thiab cov khoom siv insurface. Nws tseem raug siv los ua cov khoom noj nyob hauv cov zaub mov.

Mek yog siv los ua qhov hnyav rau ntau cov txheej txheem txheej ntau txheej, piv rau, cov nplaum yas, cov nplaum, thiab pleev pleev xim acrylic. Nws yog siv rau hauv cov xim tshem tawm, varnishes, varnishes, freeders, luam yeeb, rosins, cov kev daws teeb meem, thiab rau polymerization. Nws pom nyob rau hauv lwm cov neeg siv khoom siv, piv txwv, tsev neeg thiab cov kev nyiam ua si, thiab cov khoom lag luam ntoo. Mek yog siv nyob rau hauv dewaxing roj lubricating roj, hauv kev tsim cov hluavtaws, hauv ntawv ci thiab ua tshuaj lom neeg thiab catalyst. Nws yog kev rho tawm cov kuab tshuaj hauv kev ua cov khoom noj khoom haus thiab cov khoom noj khoom noj. Mek kuj tseem siv tau los cais kev phais thiab kho hniav.
Ntxiv rau nws cov chaw tsim khoom, ib puag ncig cov khoom ntawm mek suav nrog tso tawm ntawm lub dav hlau thiab cov haujlwm sab hauv xws li ua pa ntawm cov thee. Nws pom nyob rau hauv cov nyiaj haus luam yeeb ntau. Mek ua rau muaj kev lom neeg thiab tau txheeb xyuas tias yog cov khoom lag luam metabolism. Nws tau kuj tau pom hauv cov nroj tsuag, kab noj tsiaj, thiab mek tej zaum yog cov khoom me me ntawm cov memalian metabolism hauv cov metabolism hauv lub cev. Nws yog ruaj khov nyob rau hauv cov xwm txheej zoo tib yam tab sis tuaj yeem tsim peroxides ntawm lub caij nyoog cia; Cov no yuav tawg tau.
