Daim ntawv thov

1.Nws siv yog siv los ua cov khoom siv hluavtaws rawthicic raw rau bromination cov tshuaj tiv thaiv.

2.Qhov yog siv nyob rau hauv kev tsim cov roj hmab ntxiv.

3.Nws tseem tuaj yeem siv tau los ua cov txiv ntoo khaws cia, antiseptic thiab pwm inhibitor.

1. Bromination of Olefins thiab cov duab uas muaj ntxhiab: NBS yog siv los ntxiv cov kab sib xyaw ua ke rau cov kev sib dhos, feem ntau nyob rau hauv qhov kev txiav txim ntawm lub teeb lossis kub.

2. Dawb radical tawm tsam: NBS tuaj yeem tsim lub ntsej muag bromine, uas tuaj yeem siv tau hauv ntau lub radical dawb hloov.

3.YYnthesis ntawm bromine compounds: siv los synthesize ntau brominated orginic tebchaw, uas tuaj yeem siv los ua cov tshuaj thiab cov tshuaj ua liaj ua teb.

4. Oxidation Revenion: NBS kuj tseem tuaj yeem ua raws li cov oxidant nyob rau qee cov kev tawm tsam, txhawb kev sib xyaw ntawm cov cawv rau hauv cov cawv.

5. Dehydrogenation: Siv rau lub dehydrogenation ntawm qee cov substrates, uas pab tsim ntawm ob daim ntawv sib khi.

Hais Txog Tsheb Thauj Mus Los

* Peb tuaj yeem muab cov tsheb thauj khoom sib txawv raws li cov neeg siv 'xav tau.

* Thaum qhov ntau yog me me, peb tuaj yeem xa khoom los ntawm cov huab cua lossis thoob ntiaj teb, aws, orgs thiab ntau yam ntawm thoob ntiaj teb thauj cov kab tshwj xeeb.

* Thaum muaj nuj nqis yog loj, peb tuaj yeem xa nkoj los ntawm hiav txwv los xaiv chaw nres nkoj.

* Dhau li, peb kuj tuaj yeem muab cov kev pabcuam tshwj xeeb raws li cov neeg siv khoom siv 'kev xav tau thiab cov khoom lag luam.

Kev Cia

Muab cia rau hauv qhov cua thiab qhuav ntoo.

N-bromosuccinimide (NBS) yuav tsum khaws cia kom zoo los tswj nws cov ruaj khov thiab ua haujlwm zoo. Nov yog qee cov lus qhia rau khaws cia NBS:

1. Thawv: khw nbs rau hauv nws lub thawv qub lossis hloov mus rau lub khob ntim lossis hnab yas ntim tau sib haum nrog cov thawv tawg.

2. Kub: Khw muag NBSS hauv qhov chaw txias, qhuav kom deb ntawm kev tshav ntuj ncaj qha thiab cov khoom kub. Qhov tseeb, nws yuav tsum khaws cia ntawm chav tsev kub lossis hauv lub tub yees.

3. Cov av noo: Nco ntsoov qhov chaw cia kom qhuav yog noo noo tuaj yeem ua rau nbs kom thuam.

4. Tsis meej: Thov khaws cia ntawm cov neeg muaj zog

5. Daim ntawv lo: daim ntawv lo qhia meej nrog cov npe siv tshuaj, kev xav, thiab cov ntaub ntawv kev phom sij.

6. Kev ceev faj kev nyab xeeb: Txhua zaus yuav tsum siv hnab looj tes tsim nyog (PPE) xws li hnab looj tes thiab muab tso rau hauv ib qho chaw muaj cua zoo.

Ceev faj thaum nkoj n-bromosuccinimide?

Thaum thauj N-bromosuccinimide (NBS), ntau yam kev ceev faj yuav tsum tau noj vim nws cov tshuaj lom neeg thiab muaj kev phom sij. Nov yog qee qhov kev txiav txim siab tseem ceeb los coj mus rau hauv tus account:

1. Ua raws li kev cai: kom ua raws li kev ua raws li hauv zos, hauv tebchaws thiab thoob ntiaj teb hais txog kev thauj khoom txaus ntshai. NBS yuav raug cais raws li cov khoom siv phom sij, yog li thov saib cov lus qhia muaj feem xyuam.

2. Ntim: Siv cov ntaub ntawv ntim uas tsim nyog tau sib xws nrog NBS. Feem ntau, qhov no cuam tshuam nrog cov ntim muaj zog, xau ntim ntim uas tuaj yeem tiv thaiv lub cev kev ntxhov siab ntawm kev xa khoom. Iav lossis siab-ntom polyethylene (HDPE) cov thawv feem ntau haum.

3. Daim ntawv lo: Sau npe kom meej meej rau lub hnab ntim tshuaj, UN NUMBERS (yog tias tsim nyog), cov cim kev phom sij thiab cov ntaub ntawv kev nyab xeeb. Ua kom ntseeg tau cov ntawv cim tau pom meej.

4. Kev tswj kub: Yog tias tsim nyog siv, txiav txim siab tswj qhov ntsuas kub txwv kom tsis txhob muaj cov ntsuas kub uas tuaj yeem cuam tshuam qhov ruaj khov ntawm NBS.

5. Siv tus desiccant yog tias tsim nyog.

6. Kev rho tawm: thaum lub sijhawm thauj, khaws NBS ntawm cov khoom siv tsis sib xws xws li cov neeg sawv cev oxidizing muaj zog, txo cov tshuaj tiv thaiv thiab lwm yam tshuaj uas muaj cov tshuaj tiv thaiv.

7. Cov ntaub ntawv: suav nrog tag nrho cov ntaub ntawv xa khoom xa khoom xws li cov ntawv pov thawj kev nyab xeeb (SDS), shipping manifests, thiab ib qho xav tau.

8. Kev kawm: Ua kom cov neeg ua haujlwm tau koom nrog hauv cov txheej txheem thauj mus los yog kawm paub cov khoom lag luam txaus ntshai thiab nkag siab cov kev pheej hmoo cuam tshuam nrog nbs.
