2. Trimethyl orthopropionate CAS 24823-81-2 yog ib qho hnyav hnyav los txhim kho cov solubility ntawm cov reactants, tus neeg sawv cev sib txuas hauv cov khoom siv polymer los txhim kho cov ntaub ntawv yooj yim thiab tshuaj lom neeg, thiab yog ib qho tseem ceeb hauv kev tsim cov coatings ruaj khov thiab cov nplaum rau kev lag luam tsheb thiab kev tsim kho.
3. Cov ntawv thov ntawm Trimethyl orthopropionate kuj suav nrog nws lub luag haujlwm hauv kev tshawb fawb txog tshuaj lom neeg biology ua tus thawj coj rau kev sib xyaw ua ke ntawm cov molecules nyuaj hauv kev tshawb nrhiav tshuaj thiab kev loj hlob.
Cia thiab ceev faj
1. Khaws Trimethyl orthopropionate nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib tug inert gas nyob rau hauv ib tug txias, qhuav, thiab zoo- qhov cua qhov chaw, deb ntawm tshav kub, sparks, thiab qhib nplaim taws. Pom zoo cia kub sib txawv ntawm 0-8℃(txias) mus rau qhov txias, tsaus qhov chaw qis dua 15 degree.
2. Khaws Trimethyl orthopropionate nruj me ntsis kom deb ntawm cov muaj zog oxidizing cov neeg ua hauj, raws li nws yog incompatible, thiab tiv thaiv los ntawm noo noo vim nws maj mam hydrolyzes nyob rau hauv dej. Xyuas kom lub thawv thiab cov khoom tau txais yog grounded/bonded los tiv thaiv 静电放电 .
3. Ib txwm Trimethyl orthopropionate CAS 24823-81-2 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv, tsom iav, thiab khaub ncaws tiv thaiv. Tsuas yog siv cov khoom tawg-pov thawj thiab muaj qhov cua txaus, thiab tsis txhob ua pa pa, pos huab, lossis roj.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav, tshem tawm tag nrho cov qhov hluav taws xob, thiab muab qhov cua txaus. Muaj cov Trimethyl orthopropionate siv inert, tsis yog - cov khoom siv hluav taws xob nqus tau (piv txwv li, cov xuab zeb qhuav) thiab tiv thaiv kev nkag mus rau hauv cov dej ntws lossis cov dej.
2. Ua tib zoo sau Trimethyl orthopropionate CAS 24823-81-2 siv cov cuab yeej uas tsis muaj hluav taws xob (lossis lub tshuab nqus tsev tawg) rau hauv lub thawv ntim tshuaj khib nyiab pov tseg kom raug raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tshuaj lom neeg- khaub ncaws tiv taus thiab tus kheej- muaj cov cuab yeej ua pa (SCBA) thaum ntxuav. Trimethyl orthopropionate yog cais rau kev thauj mus los (UN3272, Hazard Class 3, PG II).
Cov ntaub ntawv kev nyab xeeb
1. Trimethyl orthopropionate yog cais raws li ib tug heev flammable kua thiab vapor (H225, txaus ntshai) nrog ib tug flash point ntawm 19℃(66℃F). Nws ua rau tawv nqaij khaus (H315) thiab khaus qhov muag loj (H319).
2. Trimethyl orthopropionate muaj teeb meem yog tias nqos, nqus tau, lossis nqus los ntawm daim tawv nqaij. Nws cov vapors tuaj yeem tsim cov khoom tawg nrog huab cua, thiab thermal decomposition ua rau cov pa phem xws li carbon monoxide.
3. Ib txwm Trimethyl orthopropionate CAS 24823-81-2 sab laj rau Daim Ntawv Qhia Kev Nyab Xeeb tshwj xeeb (SDS) rau Trimethyl orthopropionate kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P303+P361+P353 rau daim tawv nqaij, P305+P351+P3 P301+P330+P331 rau kev noj), thiab cov lus qhia tuav. Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib nplaim taws), P233 (kom kaw lub thawv kom nruj), thiab P280 (hnav looj hnab looj tes / tiv thaiv qhov muag).
