Taw qhia

Toxicological cov ntaub ntawv
Mob toxicity: qhov ncauj LD50: 70mg / kg hauv nas;
Luav percutaneous LD50: 16mg / kg;
Cov nas nqus tau LD50: 2000mg / m3 / 2h.

Cov ntaub ntawv ecological
Toxic rau cov kab mob hauv dej.Yuav ua rau muaj kev cuam tshuam tsis zoo rau cov dej ib puag ncig.
Tshuaj lom.Cov tawv nqaij hnyav thiab qhov muag khaus.

Khoom thiab Stability
Tsis txhob kub.Tsis txhob sib cuag nrog cov muaj zog oxidant, muaj zog acid, muaj zog puag, acyl chloride, anhydride.
Tshuaj lom.Nws tuaj yeem ua rau tawv nqaij thiab qhov muag.Nws raug nquahu kom hnav tsom iav thiab hnab looj tes tiv thaiv thaum ua haujlwm.

Txoj kev khaws cia

Khaws rau hauv qhov chaw txias, ventilated warehouse.Khaws kom deb ntawm qhov hluav taws kub thiab qhov cua sov.Qhov kub yuav tsum tsis pub tshaj 30 ℃.Khaws lub thawv airtight.Nws yuav tsum tau muab cais los ntawm oxidants, acids, alkalis thiab edible tshuaj, thiab yuav tsum tsis txhob muab tov.Tsis txhob khaws cia rau hauv qhov ntau lossis ntev.Cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua tshuab tau txais yuav.Tsis txhob siv cov cuab yeej siv tshuab thiab cov cuab yeej uas ua rau muaj teeb meem.Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev thiab cov khoom tuav tsim nyog.Txoj kev tswj hwm "tsib ob npaug" rau cov tshuaj lom neeg muaj zog heev yuav tsum tau ua nruj me ntsis.

Vim tias proPARgyl cawv muaj qhov taw tes qis thiab tuaj yeem hnov mob hauv qhov muaj impurities, tshwj xeeb yuav tsum tau them nyiaj rau kev nyab xeeb.Lub sij hawm luv luv cia thiab kev thauj mus los, muaj nyob hauv cov thawv tsis muaj xeb tsis muaj xeb.Rau kev khaws cia ntev, cov thawv ntim nrog cov hlau tsis muaj steel, iav lossis phenolic resin yuav tsum tau siv, thiab cov ntaub ntawv xws li txhuas yuav tsum zam.Khaws thiab thauj raws li kev cai ntawm cov tshuaj inflammable.

Siv

Siv los ua xeb tshem tawm, tshuaj lom neeg nruab nrab, corrosion inhibitor, hnyav, stabilizer, thiab lwm yam Stabilizer rau organic synthesis ntawm intermediates, hnyav thiab chlorinated hydrocarbons.

Nws tuaj yeem siv los ua hydrochloric acid thiab lwm yam kev lag luam pickling corrosion inhibitor hauv acidizing fracturing txheej txheem ntawm roj thiab roj Wells.Yuav siv tau los ua corrosion inhibitor ib leeg, nws yog qhov zoo dua kom muaj kev sib koom ua ke nrog cov khoom siv, thiaj li tau txais kev ua haujlwm zoo dua corrosion inhibition.Piv txwv li, txhawm rau txhawm rau txhim kho corrosion inhibition ntawm alkynyl cawv hauv dilute sulfuric acid tov, sodium chloride, potassium chloride, calcium chloride, potassium bromide, potassium iodide lossis zinc chloride thiab lwm yam kev siv.

Yuav siv tau los ua ib qho kev tiv thaiv corrosion ib leeg, nws yog qhov zoo dua kom muaj kev sib koom ua ke nrog cov khoom siv, thiaj li yuav tau txais kev tiv thaiv corrosion ntau dua.Piv txwv li, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhim kho cov nyhuv ntawm alkynyl cawv hauv dilute sulfuric acid tov, nws raug nquahu kom ntxiv sodium chloride, potassium chloride, calcium chloride, potassium bromide, potassium iodide lossis zinc chloride.
