Hexamethlasiloxane 丨 cas 107-46-0

Hexamethlasiloxane 丨 cas 107-46-0 (HMDSO)yog qhov tseeb, tsis muaj kob, volatile organosilicon sib xyaw nrog cov mis molecular (ch ₃) ₃SI-O-Si) ₃. Nws yog tsev neeg ntawm disiloxanes thiab tau siv dav thoob cov tshuaj synthesis, kev tsim khoom lag luam, thiab cov khoom siv tshwj xeeb xws li cov tshuaj lom tsawg, kev kub siab, thiab tshuaj lom neeg.

Cov Ntawv Thov

1. Hnyav thiab cov tshuaj tiv thaiv nruab nrab

Hmdso yog feem ntau siv raws li aTsis-Qib Sab Nraumlossis co-hnyav hauv cov txheej txheem organic thiab cov txheej txheem muaj, tshwj xeeb tshaj yog qhov twg:

Ib qho kev hloov pauv, inert cov kuab tshuaj xav tau

Dej-rhiab heev cov kev tshua tshwm sim

Tsawg toxicity thiab yooj yim ntawm kev tshem tawm los ntawm evaporation yog ntshaw

Nws yog qhov tshwj xeeb tshaj yog pab tau nyob rau hauv cov txheej txheem uas xav tau cov kuab cua tsawg.

2. Tshuaj Nruab Nrab rau Silicon-based cov ntaub ntawv

Hexamethlasiloxane ua ib qhoLub Tsev ThaivNyob rau hauv synthesis ntawm ntau yamSilicone polymers, suav nrog:

Silicone resins

Silicone Roj

Silicone Elastomers

Nws cov kev tshwm sim txhim kho lub thermal ruaj khov, hloov tau yooj yim, thiab hydrophobicity ntawm cov khoom siv.

3. Precursor rau kev kho sab saum npoo thiab txheej

Hmws yog dav siv nyob rau hauv kev tsim cov hydrophobic thiab anti-reeding txheej. Cov tswv yim suav nrog:

Tshuaj lom neeg vapor deposition (CVD) los tsim cov yeeb yaj kiab nyias

Ntshav-txhim kho kev tso nyiaj rau kev hloov kho saum npoo ntawm iav, Silicon Wafers, thiab cov hlau

Xws cov tsho muaj txiaj ntsig txhim kho cov tshuaj tua dej, txo kom muaj zog saum npoo npoo, thiab tiv thaiv tawm tsam kev xeb.

4. Siv nyob rau hauv kev lag luam semiconduct

Nyob rau hauv microelectronics, HMDSO yog siv ua aPrefursor RojNyob rau hauv ntshav ntshav-txhim kho tshuaj vapor deposition (Pecvd) kom tso nyiaj:

Silicon Dioxide-zoo li Films

Kev tiv thaiv dielectric txheej

Cov yeeb yaj kiab nyias nyias yog qhov tseem ceeb rau cov khaubncaws sab nraud povtseg thiab ua ke nyob rau hauv kev sib xyaw ua ke.

5. Hydrophobic tus neeg sawv cev thiab cov tshuaj tua dej

Vim nws cov pab methylic menprothylic thiab cov tswb pob txha caj qaum, hmSo yog thov ua cov dej-pleev xim ntxiv hauv:

Tsev luam ntawv

Cov Khoom Siv Ntawv

Cov Khoom Siv Siv

Nws txhim kho durability thiab tiv thaiv noo noo kev puas tsuaj.

6. Catalyst thiab reagent cabrier

HMDSO feem ntau siv los ua cov kuab tshuaj lossis cov cab kuj muaj cov tshuaj silosylation nrog cov silicones, muab ib qho chaw ua haujlwm hauv insertions thiab reagents.

Cov txiaj ntsig

1. Tshuaj lom neeg ruaj khov thiab inertness

Hexamethlasiloxane 丨 cas 107-46-0 yog chement ruaj khov thiab inert muaj ntau cov tshuaj tiv thaiv lossis cov cab kuj uas tsis cuam tshuam nrog cov hom kab ntsig.

2. Tsawg toxicity thiab ib puag ncig profile

Piv rau ntau cov kuab tshuaj organic, hexamethlasiloxane muaj qhov tsis tshua muaj tshuaj lom thiab ib puag ncig kev cuam tshuam, uas pab txhawb kev txhawj xeeb txog kev txhawj xeeb.

3. Volortility thiab Tshem Tawm Yooj Yim

Nws qhov chaw npau npau qis (~ 101 degree) ua rau muaj kev phom sij tov los yog cov tsho tiv no ntawm evaporation lossis distillation, cia ncaj qha ua kom huv huv ntawm cov khoom.

4. Txhim Kho Silicone Cov Khoom Siv

Raws li lub tsev thaiv rau silicones, HMDSO pab txhawb kom zoo dua:

Thermal thiab oxidative stability

Yooj taus thiab elasticity

Hydrophobicity thiab dej tsis kam

5. Ntau yam kev lag luam

Los ntawm microelectronics los tsim kho, HMDSO lub cev nqaij daim tawv thiab tshuaj lom neeg ua rau nws yoog tau yooj yim thoob plaws kev lag luam sib txawv.
