Yuav ua li cas khaws txog Centralite III?

Txhawm rau kom muaj kev nyab xeeb thiab khaws cia n-methyl-n ', n'-diphenylrea, xav txog cov lus qhia hauv qab no:

Thawv:Khaws cov tebchaw hauv cov thawv kaw ntom ntom kom tiv thaiv kom tsis txhob muaj kev paug thiab noo noo noo noo. Siv cov thawv ua cov khoom siv uas tau tshaj cov khoom siv orgone, xws li iav lossis qee yam plastics.

Kub:Khaws cia thaj chaw cia kom txias thiab qhuav. Nws yog qhov zoo tshaj plaws los khaws N-methyl-n ', n'-diphenylurea ntawm chav tsev kub, kom deb ntawm kev tshav ntuj thiab cov khoom kub. Huab cua sov heev tuaj yeem cuam tshuam rau kev ruaj ntseg ntawm cov compound.

Vaum noo:Tswj cov av noo noo qis hauv cov chaw cia kom noo tuaj yeem ua rau muaj kev cuam tshuam lossis hydrolysis ntawm cov tebchaw.

Sau npe:Daim ntawv sau kom meej lub ntim nrog lub npe tshuaj, kev xav, cov ntaub ntawv kev phom sij, thiab hnub tau txais lossis qhib.

Kev Ceev Fwm Kev Nyab Xeeb:Khaws kom deb ntawm cov ntaub ntawv tsis sib xws xws li oxidizers muaj zog lossis cov kua qaub. Xyuas kom meej tias qhov chaw cia khoom yog muaj cua zoo thiab nruab nrog cov cuab yeej tsim nyog muaj xws li cov chaw nres nkoj tsim nyog xws li cov chaw tua hluav taws.

Kev Tswj Xyuas:Txwv tsis pub nkag mus rau thaj chaw cia kom chaw cia khoom rau cov neeg ua haujlwm uas tau kawm thiab nkag siab txog cov phom sij cuam tshuam nrog cov compound.

Pov tseg:Thaum cov compound tsis xav tau lawm, thov ua raws cov cai hauv zos txog cov khib nyiab ntawm cov tshuaj pov tseg.

Ib txwm xa mus rau cov ntaub ntawv kev nyab xeeb cov ntaub ntawv (MSDS) rau n-methyl-n ', n'-diphenylurea rau kev tuav cov lus pom zoo thiab kev cia siab.

Hais txog kev thauj mus los ntawm N-methyl-n ', n'-diphenylrea?

Thaum thauj N-methyl-n ', n'-diphenylenea, nws yog ib qho tseem ceeb kom ua raws cov lus qhia kom muaj kev nyab xeeb thiab ua raws li kev cai. Nov yog qee qhov kev txiav txim siab tseem ceeb rau kev thauj cov tshuaj no:

Qhov no suav nrog cov kev cai los ntawm cov koom haum xws li Asmeskas Lub Tuam Tsev Txhawb Kev Thauj Mus Los (DOT) lossis European Chemical Lub Chaw Haujlwm (chacha).

2.Ntim: Siv cov ntaub ntawv ntim uas tsim nyog uas tau sib xws nrog n-methyl-n ', n'-diphenylurea. Lub khob ntim yuav tsum yog khov kho, sau npe thiab sau npe kom meej. Siv cov ntsaws ruaj ruaj los tiv thaiv kom tsis txhob muaj roj thaum thauj mus los.

3.Daim Ntawv Sau Npe: Sau npe kom meej rau lub hnab ntim tshuaj, lub npe, cov cim kev phom sij, thiab cov ntaub ntawv kev nyab xeeb. Qhov no suav nrog cov lus qhia daws teeb meem thiab cov ntaub ntawv tiv toj thaum muaj xwm ceev.

4. Cov kev thauj mus los: Zam kev thauj mus los ntau, noo noo, thiab kev puas tsuaj ntawm lub cev thaum thauj cov tshuaj. Zam kev tshav ntuj ncaj qha thiab khaws cia rau hauv qhov chaw muaj cua zoo.

5. Cov Ntaub Ntawv: Npaj thiab nqa tag nrho cov ntaub ntawv tsim nyog, suav nrog cov ntaub ntawv ntaub ntawv tsim nyog, nrog rau cov ntaub ntawv kev nyab xeeb (SDS), cov ntaub ntawv xa khoom, thiab cov ntawv tshaj tawm.

6.Kev Kawm: Xyuas kom cov neeg ua haujlwm tau koom nrog kev phom sij rau n-methyl-n ', n'-diphenylenya.

7.Cov Txheej Txheem Ceev: Muaj cov txheej txheem thaum muaj xwm ceev hauv qhov chaw nchuav lossis tsoo thaum thauj khoom. Qhov no suav nrog kev muaj cov khoom siv tshuaj dawb thiab cov khoom tiv thaiv tus kheej (PPE) npaj txhij.

8.Hom kev thauj: Xaiv cov qauv tsim nyog ntawm thauj (kev, huab cua, huab cua lossis hiav txwv) raws li kev deb, kev cai maj.
