Tshem tawm ntawm qhov chaw nchuav, xyuas kom muaj qhov cua txaus, thiab tsis txhob tsim cov plua plav thaum N-Acetyl-L- aspartic acid raug tso tawm, hnav cov khoom siv tiv thaiv tus kheej nrog rau cov tshuaj lom neeg- hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tshuab ua pa tsim nyog yog tias tsim nyog.
2. Sau N-acetyl-L-aspartic acid CAS 997-55-7 los ntawm cheb los yog nqus cov plua plav, siv tsis yog- cov cuab yeej hluav taws xob, lossis nqus cov kev daws teeb meem nrog cov hmoov nplej zoo-kua-binding khoom (diatomite rau hauv cov thawv ntim khoom, haum rau hauv cov thawv ntim khoom.
3. Tsis txhob tsim cov plua plav huab cua thaum lub sij hawm ntxuav kom tsis txhob ua pa tawm, decontaminate qhov chaw thiab cov khoom siv los ntawm kev txhuam nrog cawv, thiab tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov dej ntws los yog cov dej hauv chav dej vim muaj kev phom sij ib puag ncig.
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig, vim hais tias cov khoom yuav tsum muaj kev tswj cov pov tseg los ntawm cov ntawv tso cai puas tsuaj los yog tswj incineration.
Kev tiv thaiv hluav taws
1. N-Acetyl-L-aspartic acid tsis raug cais raws li cov nplaim hluav taws kub heev tab sis tuaj yeem decompose nyob rau hauv hluav taws kub, nrog lub teeb nyem ntawm kwv yees li 211℃thiab boiling point ntawm 425.3℃ntawm 760 mmHg, emitting fumes thaum koom nrog hluav taws.
2. Siv N-acetyl-L-aspartic acid CAS 997-55-7 chemical qhuav hmoov, carbon dioxide, cawv-resistant ua npuas ncauj, los yog tshuaj tsuag dej los tua hluav taws uas muaj cov khoom, xaiv cov tshuaj tua hluav taws tsim nyog raws li ib puag ncig ib puag ncig.
3. Cov neeg tua hluav taws yuav tsum hnav nws tus kheej- muaj cov cuab yeej ua pa thiab cov iav tiv thaiv tag nrho thaum tuav cov hlawv N-Acetyl-L-aspartic acid vim muaj cov pa phem xws li carbon monoxide, carbon dioxide, thiab cov pa phem uas tsim los ntawm thermal decomposition.
4. Thaum combustion, tej zaum yuav emit irritant fumes; txav cov thawv los ntawm qhov chaw tua hluav taws yog tias muaj kev nyab xeeb ua li ntawd, txias cov thawv ntim nrog cov tshuaj tsuag dej, thiab muaj cov hluav taws kub los tiv thaiv ib puag ncig.
