Corrosives kuj tuaj yeem ua rau puas lossis puas tsuaj rau hlau. Feem ntau cov corrosives yog cov acids lossis cov hauv paus. Cov kua qaub uas muaj xws li hydrochloric acid, sulfuric acid, nitric acid, chromic acid, acetic acid thiab hydrofluoric acid. Cov hauv paus feem ntau yog ammonium hydroxide, potassium hydroxide (caustic potash) thiab sodium hydroxide (caustic soda).
Ib yam li ntawd, qhov piv txwv ntawm cov khoom siv corrosive yog dab tsi?
Cov kua qaub thiab cov hauv paus yog feem ntau corrosive cov ntaub ntawv . Corrosives xws li cov no kuj qee zaum hu ua caustics. Hom piv txwv ntawm acidic corrosives yog hydrochloric (muriatic) acid thiab sulfuric acid. Hom piv txwv ntawm qhov yooj yim corrosives yog sodium hydroxide thiab lye.
Tom qab ntawd, lo lus nug yog, koj yuav pov tseg cov khoom corrosive li cas? Dispense corrosives kom zoo zoo thiab khaws cov thawv kaw thaum tsis siv. Do corrosives maj mam thiab ua tib zoo rau hauv dej txias thaum txoj hauj lwm yuav tsum sib tov corrosives thiab dej. tuav thiab pov tseg corrosive pov tseg yam xyuam xim. Xyaum ua kev tu vaj tse zoo, kev huv ntawm tus kheej thiab tu cov cuab yeej siv.
Kuj nug, dab tsi yog corrosive?
Corrosive Cov khib nyiab yog cov kua qaub lossis alkaline (piv txwv) cov khib nyiab uas tuaj yeem yooj yim corrode los yog yaj cov ntaub ntawv uas lawv tau ntsib. Peb ntsuas corrosivity los ntawm pH lossis tus nqi ntawm cov hlau corrosion : pH. Thaum cov tshuaj aqueous muaj pH tsawg dua lossis sib npaug li 2, lossis ntau dua lossis sib npaug rau 12.5 nws yog suav tias yog corrosive.
Dab tsi yog tshuaj lom neeg uas txaus ntshai tshaj plaws hauv tsev?
5 Cov Khoom Siv Hluav Taws Xob Hauv Tsev Txaus Ntshai
- Ammonia. Ammonia fumes yog ib qho ua rau khaus khaus, ua rau koj cov tawv nqaij, qhov muag, qhov ntswg, ntsws thiab caj pas.
- Tshuaj dawb. Lwm qhov tseem ceeb tab sis muaj kev nyab xeeb ntxuav, tshuaj dawb kuj muaj cov khoom muaj zog corrosive uas tuaj yeem ua kev puas tsuaj loj rau tib neeg lub cev.
- Antifreeze.
- Cov dej huv huv.
- Cua Fresheners.

Cov piv txwv ntawm kev phom sij hauv tsev yog dab tsi?
Cov ntsiab lus hauv cov teeb no (5) Asbestos. siv nyob rau hauv rwb thaiv tsev. ua rau mob qog noj ntshav. Radon. colorless, oderless, muaj kuab lom heev radioactive gas. ua rau mob ntsws cancer. Volatile Organic Compounds (VOCs) Tso tawm rau hauv huab cua los ntawm yas, naj hoom, tshuaj tua kab. Cov pa roj carbon monoxide. Tsis muaj xim thiab tsw ntxhiab. Coj. Hauv huab cua, dej haus, av, xim thiab hmoov av
Dab tsi yog qhov khoom siv phom sij?
Cov khoom siv phom sij yog ib yam khoom lossis tus neeg sawv cev (biological, tshuaj lom neeg, hluav taws xob, thiab / lossis lub cev), uas muaj peev xwm ua rau muaj kev phom sij rau tib neeg, tsiaj txhu, lossis ib puag ncig, los ntawm nws tus kheej lossis los ntawm kev cuam tshuam nrog lwm yam. Txhua tus muaj nws tus kheej lub ntsiab lus ntawm 'cov khoom muaj teeb meem.'
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 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
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
