Txo cov nplaim taws yog cov nplaim hluav taws kub uas yog ua rau muaj cov pa roj qis qis nyob ib puag 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.
Kev txo qis yog dab tsi?
Nplaim taws txo yog nplaim taws uas tsis muaj oxygen. Nws muaj xim daj lossis daj vim yog cov pa roj carbon lossis hydrocarbons uas khi nrog (lossis txo) cov pa oxygen uas muaj nyob hauv cov ntaub ntawv ua tiav nrog cov nplaim taws. Cov nplaim hluav taws txo kuj tseem hu ua cov nplaim hluav taws kub, vim nws nyiam ua kom pom cov pa roj carbon monoxide rau hauv cov hlau molten.
Lub qhov txo qis siv rau dab tsi?
Ib qhov txo cov roj oxyfuel nrog cov roj ntau dhau. Cov nplaim hluav taws txo qis feem ntau hu ua cov nplaim hluav taws kub thaum nws muab cov pa roj carbon monoxide rau saum npoo ntawm cov hlau thiab alloyed. Saib kuj Oxidizing Nplaim, Nplaim Nruab Nrab, thiab Oxyfuel Gas Vuam.
Qhov twg ntawm cov nplaim taws yog oxidizing?
Ib oxyfuel gas nplaim taws uas muaj cov pa ntau dhau, ua rau thaj chaw muaj pa oxygen txuas mus ib puag ncig thiab dhau lub khob hliav qab. Saib kuj Carburizing nplaim taws, Neutral nplaim, Txo nplaim taws thiab Oxyfuel Gas vuam.
txhais li cas los ntawm kev txo cov nplaim taws?
: nplaim taws lossis ib feem ntawm cov nplaim taws (raws li lub khob sab hauv ntawm cov nplaim hluav taws xob) muaj cov roj hlawv ib nrab thiab muaj peev xwm tshem tawm cov pa tawm ntawm ntau yam hlau oxides tso rau hauv nws.

Cov kua dej twg yog cov nplaim taws?
Flammable: Cov kua uas muaj lub teeb nyem hauv qab 100 ° F yog suav tias yog nplaim taws. Piv txwv li: roj av, acetone, toluene, diethyl ether, cawv. Yuav ua li cas yog cov nplaim taws tshaj plaws? 1) Chlorine Trifluoride yog cov pa hluav taws kub tshaj plawsNtawm tag nrho cov tshuaj lom neeg txaus ntshai, chlorine trifluoride paub tias yog cov nplaim hluav taws kub tshaj plaws.
Qhov kub twg ua rau cov nplaim taws hlawv?
Koj puas tso cai rau tus menyuam lossis koj tus kheej los tuav qee yam uas kub txaus kom yaj iav (900 degrees) lossis txhuas (1, 200 degrees)? Novelty sparklers uas feem ntau siv nyob ib ncig ntawm lub Xya Hli 4 tuaj yeem hlawv ntawm txog 1, 800 degrees!
Cov neeg tua hluav taws puas siv cov nplaim taws?
California cov neeg tua hluav taws siv cov hluav taws kub hnyiab hauv San Gabriel Toj siab rov qab hlawv cov av hauv txoj kev ntawm Bobcat hluav taws. Cov neeg tua hluav taws puas siv hluav taws? Cov neeg tua hluav taws tswj qhov hluav taws kub sib kis (lossis muab tso tawm) los ntawm kev tshem tawm ib qho ntawm peb cov khoom xyaw hluav taws kub uas yuav tsum tau hlawv:
Qhov twg tag nrho cov nqi hluav taws xob nyob ntawm qhov kev siv nyiaj siab tshaj plaws yog qhov twg?
marginal utility is zero. Tag nrho cov nqi hluav taws xob yog siab tshaj thaum marginal utility yog xoom. Qhov no yog vim muaj ntau txoj cai ntawm kev txo qis marginal utility uas hais tias tus neeg siv khoom noj ntau thiab ntau qhov zoo, qhov ntxiv rau tag nrho cov nqi hluav taws xob poob.
Qhov twg hauv qab no muab cov nplaim hluav taws kub hnyiab?
Tab sis benzene yog cov tshuaj tsw qab uas muaj cov ntsiab lus carbon ntau dua (carbon rau hydrogen piv). Yog li nws tsis tau oxidized kiag li thaum combustion thiab muab tawm sooty nplaim taws. Yuav ua li cas ua kom nplaim taws soo? Cov pa roj carbon tsis zoo tsis hlawv tag nrho thiab muab cov nplaim hluav taws uas tsis muaj hluav taws kub los yog ib nrab hlawv cov pa roj carbon monoxide.
