Kev lig kev cai, rab phom siv hauv foob pob hluav taws yog ua los ntawm 75 feem pua poov tshuaj nitrate (tseem hu ua saltpeter) tov nrog 15 feem pua charcoal thiab 10 feem pua sulfus; niaj hnub foob pob hluav taws qee zaum siv lwm cov khoom sib tov (xws li sulfurless hmoov nrog ntxiv potassium nitrate) lossis lwm yam tshuaj xwb.
Ib yam li ntawd ib tug yuav nug, dab tsi tshuaj nyob rau hauv foob pob hluav taws?
Hlau ntsev feem ntau siv hauv foob pob hluav taws cov lus qhia muaj xws li: strontium carbonate (liab foob pob hluav taws ), calcium chloride (txiv kab ntxwv foob pob hluav taws ), sodium nitrate (daj foob pob hluav taws ), barium chloride (ntsuab foob pob hluav taws ) thiab tooj liab chloride (xiav foob pob hluav taws ).
Ib sab saum toj, dab tsi yog cov roj hauv foob pob hluav taws? Charcoal
Ib yam li ntawd, tib neeg nug, dab tsi yog qhov tseem ceeb ntawm cov foob pob hluav taws?
Nplooj 1
- tacular.
- Lub hauv paus ntawm cov foob pob hluav taws feem ntau yog ib lub raj me me hu ua lub plhaub dav hlau uas muaj cov tshuaj tawg.
- Txhua lub hnub qub muaj plaub yam khoom xyaw: tus neeg sawv cev oxidizing, roj, cov xim muaj hlau, thiab cov ntawv khi.
Dab tsi yog cov txiv kab ntxwv hmoov hauv foob pob hluav taws?
Calcium - Calcium yog siv los ua kom tob foob pob hluav taws xim. Calcium ntsev tsim txiv kab ntxwv foob pob hluav taws . Carbon - Carbon yog ib qho ntawm cov khoom tseem ceeb ntawm cov xim dub hmoov , uas yog siv raws li ib tug propellant nyob rau hauv foob pob hluav taws.
