Muaj cov ntaub ntawv nyoos benzene 71-43-2

Benzene yog cov xim tsis muaj xim, cov kua pob tshab nrog cov ntxhiab tsw peculiar. Hauv qab no yog cov lus piav qhia ntawm cov khoom, siv thiab cov ntaub ntawv kev nyab xeeb ntawm Benzene:

Khoom:

• Benzene yog cov tsis tshua muaj kuab thiab cov nplaim taws thiab tuaj yeem ua cov kev sib xyaw tawg nrog cov pa oxygen hauv huab cua.
• Nws yog ib qho muaj kuab lom uas tuaj yeem tshem ntau cov tshuaj organic, tab sis yog insoluble hauv dej.
• Benzene yog kev sib xyaw nrog cov qauv sib xyaw nrog cov qauv tshuaj ruaj khov.
• Benzene yog kev ruaj khov tsis ruaj khov thiab tsis yooj yim tawg los ntawm kua qaub lossis alkali.

Siv:

• Benzene tau dav siv raws li cov khoom siv raw rau kev tsim cov khoom siv uas muaj cov ntaub, roj hmab, zas, hluavtaws thiab lwm yam.
• Nws yog ib qho tseem ceeb derobative hauv petrochemical kev lag luam, siv hauv kev tsim cov phenol, benzoic acid, Aniline thiab lwm yam sib txuas.
• Benzene kuj feem ntau siv tau siv los ua cov kuab tshuaj rau cov organic synthesis cov tshuaj tiv thaiv.

Cov Ntaub Ntawv Kev Nyab Xeeb:

• Benzene yog cov tshuaj lom thiab ntev ntev rau lossis nqus tau cov pa ntawm Benzene muaj peev xwm ua rau tib neeg muaj mob benzene tuaj yeem ua rau tib neeg muaj sia nyob, suav nrog carcinogenicity.
• Qhov cua zoo yuav tsum tau thaum siv benzene kom ntseeg tau tias nws ua haujlwm hauv ib puag ncig tsim nyog.
• Zam kev sib che daim tawv nqaij thiab nqus tau ntawm cov pa thaiv benzene thiab hnav cov hnab looj tes tiv thaiv tus kheej xws li cov hnab looj tes tiv thaiv thiab cov pa ua pa.
• Kev noj lossis haus cov tshuaj uas muaj benzene tuaj yeem ua rau tshuaj lom, cov txheej txheem kev nyab xeeb yuav tsum tau pom nruj me ntsis pom.
• Cov khib nyiab Benzene thiab Benzene-cuam tshuam yuav tsum tau daws raws li cov kev cai kom tsis txhob muaj kuab paug rau ib puag ncig thiab kev phom sij.

Gnee Dem tau tsim tsa hauv lub Peb Hlis 2014.

Lub tuam txhab tshwj xeeb hauv kev lag luam kev lag luam thoob ntiaj teb thiab tau teeb tsa nws cov sights ntawm kev ua ib qho kev sib txuas thoob ntiaj teb.

Lub tuam txhab muaj xyoo ntawm kev paub hauv kev tsim thiab muag cov tshuaj zoo, muab cov tshuaj muaj tshuaj, xyoob ntoo, thiab lwm yam khoom lag luam.

Q: Koj yuav tswj cov khoom lag luam zoo li cas?

A: 1. Peb cov khoom tsim muaj cov txheej txheem tswj hwm zoo nruj. Tag nrho cov pob yuav tso rau hauv lub tsev rau khoom tsuas yog tom qab lawv xeem cov xeem thiab ua raws li cov qauv.

2. Peb yuav tshawb xyuas thiab paub meej tias qhov khoom zoo dua ua ntej xa khoom.

Q: Koj puas muab cov kev pab ntim khoom lag luam?

A: Yog, peb muab cov kev ntim khoom ntim cov khoom lag luam, nrog cov hnab khoom, thawv, thawv, strips, thiab lwm cov ntawv ntim khoom.

Q: Ntev npaum li cas yog koj lub sijhawm khoom xa tuaj?

A: Feem ntau nws yog {5-10 hnub yog tias cov khoom nyob hauv Tshuag. Los yog nws yog {{{15-20 hnub yog tias cov khoom lag luam tsis yog inock, nws yog raws li qhov ntau.
