Cov cuab yeej tiv thaiv (PPE) suav nrog kev nyab xeeb tsom iav, tsom iav, tsom iav, hnab looj tes, lab tsho tiv no, aprons, pob ntseg plugs, thiab respirators. Tus kheej Cov cuab yeej tiv thaiv yog ua tib zoo xaiv los xyuas kom meej tias nws sib haum nrog cov tshuaj thiab cov txheej txheem siv.
Xav txog qhov no, cov khoom siv twg yog siv rau kev nyab xeeb?
Cov cuab yeej kuaj xyuas kev nyab xeeb
- Cov cuab yeej kuaj xyuas kev nyab xeeb.
- rov qab mus rau lub ntsiab Performance index ntawm CHP.
- Kev muaj thiab siv ntau hom khoom siv kev nyab xeeb yog qhov tseem ceeb rau kev coj ua ntawm kev nyab xeeb science.
- Chemical fume hoods.
- Kev nyab xeeb da dej.
- Qhov chaw ntxuav qhov muag.
- Cov hluav taws tua hluav taws.
- Daim pam hluav taws.
Qhov thib ob, kev ntsuas kev nyab xeeb hauv chav kuaj yog dab tsi? 10 Txoj Cai Kev Nyab Xeeb Tseem Ceeb Tshaj Plaws
- Txoj Cai Kev Nyab Xeeb Tseem Ceeb Tshaj Plaws.
- Paub qhov chaw ntawm Cov Khoom Siv Kev Nyab Xeeb.
- Hnav khaub ncaws rau Lab.
- Tsis txhob noj lossis haus hauv chav kuaj.
- Tsis txhob saj los yog hnia tshuaj.
- Tsis txhob ua si Mad Scientist hauv Laboratory.
- Muab pov tseg Lab pov tseg kom raug.
- Paub Yuav Ua Li Cas Nrog Lab Accidents.
Xav txog qhov no, vim li cas cov cuab yeej kev nyab xeeb tseem ceeb hauv chav kuaj?
Yog koj chav kuaj ua hauj lwm nrog tshuaj ntawm txhua yam, tshuaj fume hood yog ib qho tseem ceeb ntawm khoom siv kev nyab xeeb . Fume hoods yog cov tshuaj lom neeg- thiab hluav taws-resistant enclosures uas tiv thaiv lab cov neeg ua haujlwm los ntawm kev nqus cov tshuaj txaus ntshai los ntawm kev nqus cov vapors, gases, thiab plua plav ua ntej tso pa tawm ntawm qhov chaw chav kuaj.
Cov kev ntsuas kev nyab xeeb hauv kev soj ntsuam zaub mov yog dab tsi?
Hnav lab lub tsho tiv no thaum ua koj qhov kev sim. Koj yuav tsum hnav tsom iav los yog kev nyab xeeb tsom iav hauv chav kuaj . Lab lub tsho tiv no thiab kev nyab xeeb iav tuaj yeem sau nrog koj lub npe thiab sab laug hauv cov thawv uas yuav rov qab mus rau lab txhua lub lim tiam. Tshaj tawm yog tias cov khoom tawg lossis tsis ua haujlwm zoo.

Cov khoom twg yog cov piv txwv ntawm cov khoom siv tshuaj xyuas txhua yam uas siv?
Piv txwv ntawm cov khoom siv tshuaj muaj xws li flammability, toxicity, acidity, reactivity (ntau hom), thiab kub ntawm combustion. Hlau, piv txwv li, ua ke nrog oxygen nyob rau hauv lub xub ntiag ntawm dej los ua xeb; chromium tsis oxidize (Daim duab 2)
Dab tsi yog qhov ntsuas tus lej siv hauv pob zeb diamond kev nyab xeeb?
Cov teb xiav, liab, thiab daj-uas sawv cev rau kev phom sij rau kev noj qab haus huv, flammability, thiab reactivity, raws li-siv tus lej suav txij li 0 txog 4. Tus nqi ntawm 0 txhais tau hais tias cov khoom tseem ceeb tsis muaj kev phom sij, qhov ntsuas ntawm 4 qhia. txaus ntshai heev. Daim teb dawb yog siv los qhia cov xwm txheej tshwj xeeb
Yuav ua li cas cov khoom siv caj ces hauv txhua lub xov tooj tshiab tsim los ntawm kev faib tawm ntawm tes sib piv nrog cov khoom siv caj ces hauv lub xov tooj qub?
Mitosis tshwm sim nyob rau hauv ob lub nuclei uas zoo tib yam rau thawj nucleus. Yog li, ob lub hlwb tshiab tsim tom qab kev faib tawm ntawm tes muaj tib yam khoom siv caj ces. Thaum lub sij hawm mitosis, chromosomes condense los ntawm chromatin. Thaum saib nrog lub microscope, chromosomes pom nyob rau hauv lub nucleus
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
Yam khoom siv kev nyab xeeb twg hauv tsev kawm chav kuaj yuav tsum muaj?
Looj tsom iav dub. Raws li ib qho ntawm feem rhiab heev ntawm koj lub cev, koj ob lub qhov muag yog qhov tshwj xeeb tshaj yog muaj kev phom sij thaum koj ua haujlwm nrog cov tshuaj phem thiab cov khoom siv. Qhov chaw ntxuav qhov muag. Kev nyab xeeb da dej. Lab coats. Cov hnab looj tes tiv thaiv. Cov hluav taws tua hluav taws. Chemical fume hoods. Cov khoom siv thawj zaug
