Puas yog silicon hlau yog tshuaj txaus ntshai? Silicon hlau feem ntau tsis raug cais raws li cov tshuaj lom neeg nyob hauv nws daim ntawv pom zoo, xws li bulk lossis granular. Txawm li cas los xij, nyob rau hauv qee yam mob (xws li cov hmoov zoo los yog nyob rau hauv ib puag ncig kub), tej zaum yuav muaj qee yam kev pheej hmoo. Cov hauv qab no yog cov ncauj lus kom ntxaws txog seb cov hlau silicon yog cov tshuaj lom neeg puas tsuaj:
Puas yog silicon hlau yog tshuaj txaus ntshai?1. Cov yam ntxwv tseem ceeb ntawm cov hlau nplaum silicon
Puas yog silicon hlau yog tshuaj txaus ntshai?2. Kev faib tawm ntawm cov tshuaj lom neeg txaus ntshai
Cov tshuaj phem raug cais raws li lawv lub cev, kev noj qab haus huv thiab ib puag ncig, nrog rau cov hauv qab no:
- ignitability
- tawg
- Toxicity
- corrosivity
- reactivity
Silicon hlau feem ntau tsis ua raws li cov txheej txheem kev faib tawm saum toj no rau cov tshuaj phom sij, yog li nws feem ntau tsis suav nrog cov tshuaj phom sij. Txawm li cas los xij, nyob rau hauv cov xwm txheej tshwj xeeb, cov kev pheej hmoo hauv qab no tuaj yeem tshwm sim:
Puas yog silicon hlau yog tshuaj txaus ntshai?3. Muaj peev xwm txaus ntshai ntawm cov hlau nplaum silicon
(1) Plua plav tawg txaus ntshai
Kev piav qhia ntawm qhov xwm txheej:
Vim yog cov khoom me me thiab thaj chaw loj ntawm cov hlau silicon hmoov, thaum nws nce mus txog qee qhov concentration hauv cov huab cua (xws li 30-100 g/m³), nws yuav ua rau cov hmoov av tawg thaum qhib hluav taws lossis hluav taws xob hluav taws xob.
Kev tiv thaiv:
Tswj qhov concentration ntawm plua plav hauv qhov chaw ua haujlwm thiab tswj qhov cua.
Tsis txhob qhib nplaim taws, hluav taws kub nyhiab, thiab qhov chaw kub.
(2) Kev kub siab tiv thaiv kev pheej hmoo
Kev piav qhia ntawm qhov xwm txheej:
Nyob rau hauv qhov chaw kub kub (siab tshaj 700 ° C), nws yog xim hlau silicon yuav ua rau muaj kev kub ntxhov nrog oxygen los ua silicon dioxide (SiO 2) thiab tso cua sov ntau.
Kev tiv thaiv:
Tsis txhob kov ncaj qha nrog hlau silicon kub kub lossis lwm yam muaj zog oxidation.
(3) Tshuaj lom neeg muaj kev pheej hmoo
Kev piav qhia ntawm qhov xwm txheej:
Thaum nws yog xim hlau silicon reacts nrog cov kua qaub uas muaj zog (xws li hydrofluoric acid), nws tuaj yeem tsim cov roj hluav taws xob (xws li silane, SiH 4).
Kev tiv thaiv:
Khaws kom deb ntawm cov kua qaub.
Tsis txhob sib cuag nrog cov kua qaub thaum ua haujlwm.

Tuam Tshoj Hazardous Chemical Catalog
Cov qauv thoob ntiaj teb (xws li GHS)
Puas yog silicon hlau yog tshuaj txaus ntshai?5. Muaj kev nyab xeeb siv thiab tswj cov lus qhia
Txawm hais tias silicon hlau tsis yog tshuaj lom neeg, rau kev nyab xeeb, nws tseem tsim nyog los tswj hwm nws qhov chaw cia thiab siv ib puag ncig:
(1) Cov kev cai cia khoom
(2) Cov kev cai thauj mus los
(3) Kev nyab xeeb ua haujlwm
Puas yog silicon hlau yog tshuaj txaus ntshai?6. Cov ntsiab lus
Silicon hlau nyob rau hauv nws cov lus pom zoo (thaiv los yog granular) feem ntau tsis suav hais tias yog tshuaj lom neeg thiab yog cov khoom siv ruaj khov. Txawm li cas los xij, nyob rau hauv lub xeev hmoov los yog nyob rau hauv tshwj xeeb tej yam kev mob (xws li kub kub, muaj zog oxidizing ib puag ncig), tej zaum yuav muaj kev pheej hmoo ntawm plua plav tawg thiab reactivity. Yog li ntawd, nyob rau hauv cov txheej txheem ntawm kev khaws cia, kev thauj mus los thiab kev siv, kev tiv thaiv tsim nyog yuav tsum tau ua raws li daim ntawv tshwj xeeb thiab siv los ua kom muaj kev nyab xeeb.
