UN1593 Muaj Qib Methylene Chloride yog cov tshuaj hnyav hnyav siv rau ntau yam kev lag luam. Methylene chloride, tseem hu ua dichloromethane, yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw qab. Nws muaj qhov kub kub kub thiab yog soluble hauv feem ntau cov kuab tshuaj organic.

Methylene chloride feem ntau yog siv los ua cov kuab tshuaj rau cov xim, cov kua roj vanish, thiab cov nplaum, nrog rau kev tsim cov tshuaj thiab cov yas. Nws kuj yog siv los ua tus neeg sawv cev stripping rau tu thiab degreasing hlau nto.

Thaum siv los ua tus neeg sawv cev stripping, methylene chloride yog cov kuab tshuaj zoo rau kev tshem tawm cov xim, kua roj vanish, thiab lwm yam txheej txheej los ntawm cov hlau. Nws kuj yog siv los tshem tawm cov coatings los ntawm cov khoom yas.

Txawm li cas los xij, methylene chloride yog cov tshuaj lom neeg uas muaj peev xwm ua rau muaj kev phom sij loj yog tias tsis siv kom raug. Kev raug methylene chloride vapors tuaj yeem ua rau khaus ntawm qhov muag, qhov ntswg, caj pas, thiab ua pa. Kev raug mob ntev tuaj yeem ua rau kiv taub hau, mob taub hau, thiab txawm tias tsis nco qab.

Vim tias cov kev pheej hmoo no, nws yog ib qho tseem ceeb los tswj UN1593 Industrial Grade Methylene Chloride Stripping Chemical Solvent nrog kev saib xyuas thiab ua raws li tag nrho cov kev tiv thaiv kev nyab xeeb tsim nyog thaum siv nws hauv txhua txoj kev lag luam. Nws tseem pom zoo kom khaws cia rau hauv qhov chaw ruaj ntseg thiab zoo-ventilated.

UN1593 yog cov khoom siv phom sij rau aviation roj av (avgas). Nws yog ib tug heev flammable kua siv los ua roj nyob rau hauv piston-engine aircraft. Nws yuav tsum muaj kev tuav tshwj xeeb, khaws cia, thiab kev ceev faj txog kev thauj mus los vim nws qhov phom sij ntawm qhov hluav taws kub thiab muaj peev xwm ua rau hluav taws kub thiab tawg. Thaum thauj UN1593, United Nations Dangerous Goods cov cai yuav tsum tau ua raws li kom ntseeg tau tias nws txoj kev thauj mus los nyab xeeb.

Methylene Chloride, tseem hu ua dichloromethane, yog cov kua tsis muaj xim, tsis muaj zog, thiab nplaim taws uas muaj ntxhiab tsw qab. Nws yog ib qho chlorinated hydrocarbon uas yog dav siv los ua cov kuab tshuaj, xim stripper, thiab degreaser.

UN1593 yog tus lej cim uas tau muab rau Methylene Chloride los ntawm United Nations Committee of Experts on the Transport of Dangerous Goods. Tus lej no yog siv los faib cov khoom siv thiab tswj nws txoj kev thauj mus los raws li International Maritime Dangerous Goods Code (IMDG), International Air Transport Association (IATA) Cov Cai Tswj Kev Nyab Xeeb Kev Nyab Xeeb, thiab Tebchaws Meskas Lub Tsev Haujlwm Saib Xyuas Kev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb (USDOT).

Methylene Chloride raug cais raws li cov khoom siv phom sij vim nws qhov flammability, toxicity, thiab muaj peev xwm ua rau muaj kev puas tsuaj rau ib puag ncig. Nws yog ib qho tseem ceeb los tuav thiab thauj cov khoom no raws li cov cai tswj kev nyab xeeb uas tsim los ntawm cov tub ceev xwm cuam tshuam.
