Physicochemical muaj:

Qhov khoom muaj tus ntxhiab tsw muaj Ammonia, nws yog ib qho alkaline thiab yooj yim rau assorb tus CO2, muaj ua rau cov tshuaj uas muaj water(Acohol). Cov tetramethylammonium hydroxide 5 siv lead ua dej yog acicular siv lead ua tsis muaj kob thiab diliquescence. Melting kis yog 63℃. Qhov kub taw tes yog 120℃。 Nws yuav decomposite trimethylamine thiab methanol thaum cua sov rau biling. Yog tus ceev cov khoom muag hauv 1.00(25/4℃), thiab nws yog ib tug alkali mater uas muaj zog corrosive. Txhob cia tus foob packing. Nws yog ib qho yooj yim moisure haum las pa. Decomposition kis yog 134℃. Peb hu nws "ib ntus catalyst lawm" ntawm nws lub qho yooj yim uas yuav ntxuav tom qab siv raws li cov catalyst thiab tsis tau tawm hauv tej residue.

Cov tetramethylammonium hydroxide yuav muab siv ua polarographic reagent rau cov ntoo av tshauv dawb hydride nag lossis daus thaum peb analysising.

Cov khoom siv:

Cov catalyzer los simemethylphenyl siloxane fliud, Silicone roj diffusion twj, kuab dawb silicone molding yas, organic siliconresin, silicon roj hmab.

Polarographic reagent nyob hauv kev cais.

Khoom purification: yuav muab coj los ua ntoo av tshauv dawb alkali, depost lub caij nws yog xim hlau.

Brightener xab npum, hu rau substanceto thaum yuav ua tau ib nplais silicon.

Phaj Circuit Court xab npum ntegrated thiab cov etchant hauv tshuab Semiconductor micro ua anisotropic.

Lub abluent los rau CMP, zoo, photoresist develper ICVLSI thiab TFI-LCD.

Tau lug siv polyester polymer, spinning, uas, zaub mov, tawv, ntoo

ntxuav, electroplate, tug kab mob tom teb.


Cia thiab tiv thaiv

Cov khoom no yooj yim rau deliquescences, thov muab khi ncauj cia, chaw dim pa thiab kom qhuav thiab txhob cia dej thiab insolation, zam ntawm breathingin, ob lub qhov muag hu los yog nqos. Hnav tiv khoom, tom qab kev khiav hauj lwm, ntxuav hauv dej. Tsis muaj noj.

Cov: tau, lam fwj, hnab, thawv, kua li, yas nruag
