Qhov tseem ceeb tshaj plaws, TSIS TXHOB muab ob lub tshuab ntxhua khaub ncaws sib txawv ua ke, tshwj xeeb tshaj yog cov khoom muaj ammonia thiab chlorine (bleach). Qhov sib xyaw no tuaj yeem ua rau muaj cov pa roj hu ua chloramine, uas tuaj yeem ua rau muaj teeb meem ua pa hnyav thiab ua rau tuag taus yog tias nqus tau ntau heev.
Kuj paub, dab tsi yog cov khoom ntxuav tu txaus ntshai tshaj plaws?
Cov feem ntau mob heev Cov khoom siv ntxuav tu txaus ntshai yog cov tshuaj ntxuav dej corrosive, ntxuav qhov cub, thiab cov tshuaj ntxuav tais diav acidic, raws li Washington Toxics Coalition. Yuav khoom siv ntxhua khaub ncaws, ntxhua khaub ncaws, thiab tu tus kheej cov khoom sau tias "tsis muaj ntxhiab" lossis "tsis muaj ntxhiab".
Ib sab saum toj no, dab tsi yog cov tshuaj lom neeg hauv tsev txaus ntshai tshaj plaws? 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.
Tom qab ntawd, cov khoom siv hauv tsev twg ua rau tuag taus?
Cov npe hauv qab no muab cov lus qhia rau cov khoom siv hauv tsev uas tuaj yeem ua rau koj xav tsis thoob
- 3 Rooj tog Polish.
- 4 Extension Cords.
- 5 Lead Xim.
- 6 Lub tshuab ziab khaub ncaws.
- 7 Mothball.
- 8 Qhov cub.
- 9 Tshuaj txhuam hniav.
- 10 Bleach. Bleach, uas yog npaj los ntxuav txawm tias qhov phem tshaj plaws, tuaj yeem ua rau muaj kev phom sij heev.
Kev sib xyaw cov khoom ntxuav puas tuaj yeem tua koj?
Sib tov tshuaj bleach nrog rau cov kua dej cawv kuj yuav ua rau ob peb teeb meem li ob tshuaj react ua ke los tsim cov tshuaj lom chloroform gas nrog rau hydrochloric acid. chloroform ntau dhau ua tau ua rau koj hla dhau los yog txawm tua koj thaum lub acid ua tau muab koj hluav taws kub.

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)
Kuv tuaj yeem siv dab tsi los tua cov nyom?
Cov tshuaj tua kab uas muaj permethrin thiab carbaryl muaj txiaj ntsig zoo tshaj plaws los tua cov nyom
Koj tuaj yeem siv txoj cai khoom siv tsis yog txoj cai quotient?
Muaj ob qhov laj thawj vim li cas txoj cai quotient tuaj yeem ua tau zoo dua rau txoj cai tswj hwm lub zog ntxiv rau cov khoom lag luam hauv kev sib txawv ntawm cov quotient: Nws khaws cov denominators thaum simplifying qhov tshwm sim. Yog tias koj siv txoj cai fais fab ntxiv rau cov khoom siv, feem ntau koj yuav tsum nrhiav ib tus lej sib piv kom yooj yim rau qhov tshwm sim
Txoj cai thermodynamic twg hais tias koj Tsis tuaj yeem hloov 100 feem pua ntawm cov cua sov rau hauv cov khoom siv hluav taws xob ntawm cov lus teb xaiv?
Txoj Cai thib ob
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
