Qhov sib txawv tseem ceeb ntawm oxidizing thiab txo cov nplaim hluav taws yog cov nplaim hluav taws oxidizing yog tsim nyob rau hauv lub xub ntiag ntawm cov pa ntau dhau, qhov txo cov nplaim taws yog tsim nyob rau hauv lub xub ntiag ntawm cov pa qis.
Peb siv ntau hom burners hauv ntau daim ntawv thov; Piv txwv li, Bunsen burner hauv analytical laboratory. Cov burners no tsim cov nplaim taws sib txawv nyob ntawm seb cov pa oxygen nyob ib ncig ntawm lub qhov cub. Cov nplaim hluav taws no tuaj yeem muab faib ua oxidizing, txo thiab nruab nrab nplaim taws.
Oxidizing nplaim yog dab tsi?
Oxidizing nplaim yog cov nplaim hluav taws kub hnyiab uas ua rau muaj cov pa oxygen ntau dhau. Thaum muaj cov pa ntau dhau ntawm cov pa oxygen nyob ib ncig ntawm lub qhov cub, lub qhov cub hluav taws xob tsim hluav taws xob luv luv. Cov nplaim luv luv no kuj muaj xim tsaus. Tsis tas li ntawd, cov nplaim hluav taws oxidizing zoo li nws nrov nrov thiab nrov nrov.
Daim duab 01: Oxygen-Rich Surrounding Forms a Short Flame
Feem ntau, cov nplaim hluav taws no yog qhov tsis xav tau rau lub hom phiaj vuam. Qhov no yog vim cov nplaim hluav taws oxidizing no tuaj yeem oxidize cov hlau nto, raws li nws lub npe qhia.
Dab tsi yog Txo Nplaim
Txo cov nplaim taws yog cov nplaim taws uas ua rau muaj cov pa oxygen tsawg nyob ib ncig ntawm lub qhov cub. Feem ntau, thaum tsis muaj oxygen txaus nyob ib ncig ntawm lub qhov cub, cov nplaim yuav daj lossis daj. Qhov no yog vim muaj cov pa roj carbon lossis carbon-muaj cov khoom sib txuas xws li hydrocarbons. Cov pa roj carbon atoms nyiam ua ke nrog cov pa oxygen atoms thiab tsim cov nplaim hluav taws. Yog li ntawd, hom nplaim hluav taws no tseem hu ua nplaim hluav taws. Qhov no yog vim cov nplaim hluav taws no tuaj yeem qhia cov pa roj carbon rau hauv cov hlau molten. Txo cov nplaim taws yog qhov tseem ceeb hauv kev sib tsoo thiab kev sib tsoo.
Daim duab 02: Cov nplaim hluav taws sib txawv - Txo cov nplaim taws (sab laug kawg) thiab nplaim hluav taws kub (txoj cai tshaj)
Neutral nplaim taws, ntawm qhov tod tes, kuj tseem ceeb hauv kev sib tsoo thiab kev sib tsoo. Cov nplaim hluav taws no yog tsim thaum muaj cov pa oxygen txaus nyob ib puag ncig ntawm lub qhov cub, tab sis cov ntsiab lus oxygen tsis pub dhau qhov txwv ntawm qhov yuav tsum tau muaj cov pa oxygen. Yog li ntawd, tsis muaj oxidation lossis txo qhov tshwm sim ntawm no. Cov nplaim taws no tshwm sim xim xiav vim tias muaj cov pa oxygen zoo.
Qhov txawv ntawm Oxidizing thiab txo cov nplaim taws yog dab tsi?
Cov hluav taws kub sib txawv tsim cov nplaim hluav taws sib txawv nyob ntawm seb cov pa oxygen nyob ib puag ncig lub qhov cub. Qhov sib txawv tseem ceeb ntawm oxidizing thiab txo cov nplaim hluav taws yog tias cov nplaim hluav taws oxidizing yog tsim nyob rau hauv lub xub ntiag ntawm ntau cov pa oxygen, thaum txo cov nplaim hluav taws yog tsim nyob rau hauv lub xub ntiag ntawm cov pa qis. Oxidizing nplaim tuaj yeem oxidize hlau qhov chaw thaum txo cov nplaim taws tuaj yeem txo cov hlau molten. Yog li, oxidizing nplaim taws tsis haum rau soldering thiab annealing lub hom phiaj, tab sis txo cov nplaim taws yog qhov zoo rau ob daim ntawv thov no.
Ntxiv mus, qhov pom qhov sib txawv ntawm oxidizing thiab txo cov nplaim taws yog cov nplaim hluav taws xob luv luv thiab muaj xim tsaus thaum txo cov nplaim taws ntev thiab daj lossis daj.
Koj tuaj yeem pom cov ntsiab lus ntxiv hauv cov duab hauv qab no ntawm qhov sib txawv ntawm oxidizing thiab txo cov nplaim taws.
Summary – Oxidizing vs Txo Nplaim
Cov hluav taws kub sib txawv tsim cov nplaim hluav taws sib txawv nyob ntawm seb cov pa oxygen nyob ib puag ncig lub qhov cub. Qhov sib txawv tseem ceeb ntawm oxidizing thiab txo cov nplaim taws yog cov nplaim hluav taws oxidizing yog tsim nyob rau hauv lub xub ntiag ntawm ntau cov pa oxygen, thaum txo cov nplaim hluav taws yog tsim nyob rau hauv lub xub ntiag ntawm cov pa qis.
