Cov hluav taws tua hluav taws yog cov cuab yeej tua hluav taws tseem ceeb uas feem ntau saib tsis tau hauv lub sijhawm ib txwm tab sis dhau los ua qhov tseem ceeb hauv kev kub ntxhov. Tshwj xeeb tshaj yog niaj hnub no, nrog rau siab - cov tsev nce siab thiab sab hauv dai kom zoo nkauj nrog ntau cov ntoo, yas, thiab ntaub, hluav taws kub tsis muaj cov cuab yeej tua hluav taws yuav ua rau muaj kev puas tsuaj.
Cov tua hluav taws thaum ntxov yog qhov yooj yim heev, feem ntau yog cov hooks, axes, shovels, thiab thoob. Thawj qhov hluav taws kub tua hluav taws tau tsim nyob rau xyoo 1816 los ntawm Tus Thawj Tub Rog Manby, tus thawj coj ntawm Norfolk thiab Askiv tus thawj coj nkoj. Nws tsuas muaj ib los yog ob lub cylindrical ntim ntim nrog me ntsis tshaj li ib liter dej thiab compressed cua.
Los ntawm nruab nrab-19th caug xyoo, Fabkis tus kws kho mob Gallier tau tsim cov tshuaj tua hluav taws uas siv tau. Sodium bicarbonate thiab dej tau sib xyaw rau hauv lub thawv, thaum lub khob iav uas muaj sulfuric acid tau muab tso rau hauv qhov qhib. Thaum siv, tus pin tawm tsam tawg lub raj mis, ua rau cov tshuaj sib tov thiab tsim cov pa roj carbon dioxide, yuam cov dej tawm ntawm lub thawv.
Xyoo 1905, Xib Fwb Laurent ntawm Russia tau tsim ib tus neeg ua npuas dej tua hluav taws hauv St. Nws tov aluminium sulfate nrog sodium bicarbonate tov thiab ntxiv ib tug stabilizer; Thaum txau, nws tsim ua npuas ncauj uas muaj carbon dioxide. Cov npuas dej no ntab rau ntawm cov roj hlawv, pleev xim, lossis roj av, tshem tawm cov pa oxygen thiab ua kom cov nplaim taws.
Xyoo 1909, Davidson ntawm New York tau txais daim ntawv pov thawj rau kev siv cov pa roj carbon dioxide los ua kom cov pa roj carbon tetrachloride los ntawm lub tshuab tua hluav taws. Cov kua no tam sim ntawd hloov mus ua ib qho uas tsis yog -flammable, hnyav dua roj kom smother cov nplaim taws. Tom qab ntawd, ntau yam hluav taws tua hluav taws me me, xws li cov hmoov tua hluav taws qhuav thiab cov kua roj carbon dioxide tua hluav taws, tau tsim.
