Tom ntej: Hexamethyldisilazane CAS 999-97-3

1. Hexamethyldisilazane yog siv dav hauv kev tsim khoom semiconductor rau kev hloov kho saum npoo, txhim kho adhesion thiab hydrophobicity ntawm substrates los txhim kho cov khoom siv hluav taws xob. Nws kuj tseem ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm silicon-raws li polymers, nanomaterials, thiab silicon nitride rau siab - ceramics .
2. Hexamethyldisilazane CAS 999-97-3 yog tus qauv derivatisation tus neeg sawv cev hauv cov roj chromatography-mass spectrometry (GC-MS), siv los ua kom cov volatility ntawm polar compounds kom zoo dua chromatographic sib cais thiab nrhiav kom tau. Nws kuj tseem muaj txiaj ntsig zoo hauv kev tsim cov txheej tiv thaiv rau cov hlau thiab iav, muab kev tiv thaiv corrosion thiab hnav hauv tsheb thiab aerospace industries.
3. Cov ntawv thov ntawm Hexamethyldisilazane suav nrog nws siv los ua cov organic synthesis nruab nrab thiab tshuaj ntsuam reagent, nrog rau kev tshawb fawb los tsim cov molecules complex nrog precision thiab efficiency.

1. Khaws Hexamethyldisilazane nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv inert gas (piv txwv li, nitrogen) nyob rau hauv ib tug txias, qhuav, thiab zoo - qhov cua qhov chaw, raws li nws hydrolyzes nkag tau rau ntawm noo noo. Pom zoo cia yog nyob rau ntawm chav tsev kub (RT) nyob rau hauv ib qho chaw txias, tsaus.
2. Khaws Hexamethyldisilazane nruj me ntsis kom deb ntawm tshav kub, sparks, qhib nplaim taws, muaj zog oxidizing neeg sawv cev, thiab muaj zog acids. Nws yog ib qho hluav taws kub heev (flash point 11-27 degree) thiab tsim cov khoom tawg nrog huab cua.
3. Ib txwm Hexamethyldisilazane CAS 999-97-3 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov tsom iav kom ruaj ntseg, tshuaj lom neeg- hnab looj tes tiv thaiv (nitrile roj hmab, qhov tsawg kawg nkaus 0.4 hli thickness rau kev tiv thaiv tag nrho), thiab nplaim hluav taws tiv thaiv cov khaub ncaws tiv thaiv zoo li qub. Tuav tsuas yog nyob rau hauv qhov chaw uas muaj cua zoo los yog fume hood thiab tsis txhob ua pa vapors, pos huab, los yog roj.

1. Tam sim ntawd cais qhov chaw nchuav, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab xyuas kom muaj cua txaus. Siv cov cuab yeej tiv thaiv tus kheej tag nrho suav nrog tus kheej - muaj cov cuab yeej ua pa (SCBA). Tsis txhob cia Hexamethyldisilazane nkag mus rau hauv cov dej ntws los yog txoj kev hauv dej, vim nws muaj kev phom sij rau cov dej hauv dej.
2. Muaj Hexamethyldisilazane siv qhuav, inert, tsis yog -cov khoom siv hluav taws xob (xws li Chemizorb®). Ua tib zoo sau cov khoom tsis huv uas siv tsis yog- cov cuab yeej hluav taws xob rau hauv lub thawv kaw, sau cov tshuaj khib nyiab pov tseg kom raug raws li cov cai tswj kev phom sij.
3. Tus neeg ua haujlwm Hexamethyldisilazane CAS 999-97-3 yuav tsum hnav PPE haum thaum ntxuav. Nyob rau hauv cov xwm txheej hluav taws kub, siv cov pa roj carbon dioxide (CO₂) los yog hmoov qhuav los tua cov xov xwm; Tsis txhob siv ua npuas ncauj lossis dej. Hexamethyldisilazane yog cais rau kev thauj mus los (UN1992 lossis UN3286, Hazard Class 3/6.1, Packing Group II).

1. Hexamethyldisilazane yog cais nrog GHS teeb liab lo lus "Danger". Nws yog cov nplaim hluav taws kub heev (H225), ua rau tawv nqaij kub hnyiab thiab qhov muag loj (H314/H318), muaj tshuaj lom yog tias nqus tau (H331), tiv tauj nrog daim tawv nqaij (H311), thiab muaj teeb meem yog nqos tau (H302). Cov ntaub ntawv mob toxicity: LD50 qhov ncauj nas 851 mg/kg, LC50 inhalation nas 10 mg/l/6h, LD50 dermal luav 547-589 mg/kg.
2. Hexamethyldisilazane yog noo noo rhiab heev thiab decomposes thaum sib cuag nrog dej los yog huab cua ntub, tso ammonia. Nws muaj qhov kub ntawm 125-126 degree, melting point ntawm -78 degree, ntom 0.77 g / mL, yog insoluble nyob rau hauv dej tab sis soluble nyob rau hauv feem ntau cov organic solvents. Thermal decomposition ua rau cov pa phem thiab khaus xws li carbon oxides, nitrogen oxides (NOx), thiab silicon oxides. NFPA kev ntsuam xyuas kev noj qab haus huv yog 1 (kev khaus khaus nkaus xwb), tab sis qee qhov chaw qhia tias muaj kev phom sij ntau dua nrog H311 / H331 kev ntsuas.
3. Nco ntsoov sab laj nrog Hexamethyldisilazane CAS 999-97-3 daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Hexamethyldisilazane kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P305+P351+P338+P310 rau qhov muag, P303+P{3}, P{2}} P304+P340+P310 rau kev nqus pa, 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), P260 (tsis txhob ua pa tawm), P273 (tsis txhob tso rau ib puag ncig), thiab P280 (coj hnab looj tes tiv thaiv / qhov muag tiv thaiv).
