Thaum ntxuav cov kab mob tom qab muaj cov tshuaj lom ntawm qhov chaw tsim kho, cov tshuaj ntxuav cov khoom siv feem ntau suav nrog cov tshuaj tsis muaj zog acidic lossis tsis muaj zog alkaline neutralizing, tsis yog - cov tshuaj tua hluav taws kub, cov khoom siv adsorbent, thiab cov tshuaj ntxuav tshwj xeeb. Cov kev xaiv tshwj xeeb ntawm tus neeg sawv cev yuav tsum tau txiav txim siab raws li cov khoom siv tshuaj lom neeg ntawm cov khoom uas nchuav los ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo ntawm kev tshem tawm cov kab mob.
Sib piv cov tshuaj ntxuav tu rau hom spilled
1. Cov kua qaub kua qaub (xws li Hydrochloric Acid, Sulfuric Acid)
Common Cleaning Agents:
Sodium bicarbonate tov (baking soda tov)
Limewater los yog calcium hydroxide suspension
Soda tshauv (sodium carbonate) tov
Mechanism of Action: Los ntawm cov kua qaub- cov tshuaj tiv thaiv tsis zoo, cov kua qaub muaj zog tau hloov mus rau cov ntsev thiab dej tsis zoo, yog li txo cov kev pheej hmoo cuam tshuam nrog corrosivity thiab toxicity.
Cov lus pom zoo ua haujlwm: Ntxiv tus neeg sawv cev nruab nrab maj mam thaum nplawm kom tsis txhob muaj kev kub ntxhov los yog txaws; tom qab neutralization, yaug qhov chaw kom huv si nrog ntau qhov dej huv.
2. Cov tshuaj alkaline (piv txwv li, Sodium Hydroxide, Aqueous Ammonia)
Common Cleaning Agents:
Dilute acetic acid daws
Citric acid daws
Boric acid daws
Mechanism of Action: Cov kua qaub tsis muaj zog yog siv los ua kom tsis muaj zog hauv paus, tsim cov ntsev thiab dej soluble, uas txo cov tawv nqaij thiab ib puag ncig.
Cov Lus Qhia Txog Kev Ua Haujlwm: Tsis txhob siv cov kua qaub uas muaj zog (xws li hydrochloric acid) los tiv thaiv kev tawm tsam hnyav heev; Kev yaug nrog dej huv yog tseem xav tau tom qab neutralization.
3. Cov kuab tshuaj Organic los yog roj (xws li, Xim, Thinners, Ethanol)
Common Cleaning Agents:
Tsis yog- cov khoom siv hluav taws xob uas muaj hluav taws xob (piv txwv li, dej- cov tshuaj ntxuav tes)
Tshwj xeeb degreasers lossis roj tshem tawm
Organic kuab tshuaj xws li ethyl acetate los yog acetone (siv rau theem nrab tu)
Cov khoom siv pabcuam: Cov ntaub qhwv ntsej muag / paj rwb, xuab zeb, vermiculite, thiab lwm yam, siv rau thawj zaug nqus ntawm cov kua dej.
Cov yam ntxwv tseem ceeb: Dej- cov tshuaj ntxuav raws li ib puag ncig tus phooj ywg thiab tsis yog -flammable, ua rau lawv haum rau tu thaj chaw loj ntawm -site; cov kuab tshuaj organic yog siv rau cov khoom tawv tawv, txawm hais tias yuav tsum tau saib xyuas txog qhov cua thiab kev tiv thaiv hluav taws.
