Hluav taws yog ib qho ntawm cov kev phom sij tshaj plaws hauv lub neej txhua hnub, ua cov khoom siv hluav taws kub rau cov tsev, chaw ua haujlwm, thiab chaw ua haujlwm. TusSodium bicarbonate tuaSiv sodium bicarbonate raws li nws thawj zaug tua hluav taws thiab tau dav siv rau kev sib txuas hluav taws me, tshwj xeeb yog cov hluav taws kub.
Lub ntsiab cai ntawm kev ua haujlwm
Sodium bicarbonate (nhcox) yog ib qho kev sib txuas ua ke uas muaj kev sib txuas ua ke uas muaj kev kub siab, tsim cov pa roj carbon dioxide (COUNT), dej vaponate. Nws cov txheej txheem hluav taws-extinguishing xws li cov kauj ruam hauv qab no:
Txias nyhuv:
Tso tawm npib sai sai diffuses thiab nqus tshav kub los ntawm cov hluav taws, txo qhov kub.
Smothering nyhuv:
Cov inert bol roj ua ib txheej dhau ntawm thaj chaw hlawv, txiav tawm cov khoom siv oxygen, txiav ib qho ntawm peb qhov kev sib txuas.
Kev rho tawm cov nyhuv:
Residual sodium carbonate npog qhov saum npoo ntawm cov khoom hlawv, cais nws los ntawm huab cua thiab tiv thaiv rov nkag siab.
Cov Ntawv Thov
Cov sodium Bicarbonate Extinguuuuuuuuisher yog feem ntau rau cov hluav taws hauv qab no:
Chav kawm b figh (kua roj): Hluav taws uas cuam tshuam nrog cov tshuaj xws li roj av, diesel, thiab pleev xim.
Chav kawm chla (gases gases): Hluav taws tshwm sim los ntawm cov pa roj, muaj txiaj ntsig, lossis hydrogen.
Hluav Taws Xob Hluav Taws Xob: Qhov zoo tagnrho rau cov hluav taws uas cuam tshuam nrog cov khoom siv hluav taws xob vim nws cov tshuaj lom neeg tsis muaj tshuaj lom neeg.
Tsab ntawv: Cov tshuaj tua hluav taws no tsis haum rau chav kawm hluav taws (zoo tib yam combustibles zoo li ntoo lossis ntawv) vim nws qhov kev txias me me thiab nkag mus.
Sodium Bicarbonate Zoo yuav tsum muaj rau cov tshuab tua hluav taws
Qhov zoo ntawm sodium bicarbonate cuam tshuam ncaj qha cuam tshuam cov ua tau zoo, kev nyab xeeb, thiab kev ua haujlwm ntawm lub tua hluav taws. Hauv qab no yog cov tseev kom tseem ceeb:
1. Kev coj dawb huv
Siab huv:
Sodium Bicarbonate rau cov extinguishers yuav tsum muaj qib purity ntawm ntau dua 99% kom ntseeg tau tias kev cuam tshuam tsis zoo los ntawm kev siv tshuaj tsis zoo lossis tsis xav tau tshuaj lom neeg.
Tsis tshua muaj cov ncauj lus:
Ntau ntau ntawm cov tshuaj chlorides, sulfides, lossis lwm yam paug uas yuav ua rau muaj kev cuam tshuam tsis zoo lossis cov khoom siv durability yuav tsum tau zam.
2. Qhov loj me me
Kev faib cov khoom sib faib:
Cov lus yuav tsum yog tusyees tusyees, feem ntau nyob rau hauv thaj tsam ntawm 20-75 microns. Cov nplais me txhim kho kev pab them nqi, thaum ntau cov loj yuav ua rau paug tawm.
Anti-Caking Cov Khoom:
Cov qauv tsim qauv partic yuav tsum tiv thaiv clumping vim ya raws kev nqus dej noo, ua kom muaj kev tshem tawm hmoov zoo.
3. Kev nqus dej noo thiab kev tsis kam
Tsawg Hygroscopicity:
Sodium bicarbonate yog ib txwm hygroscopic. Kev kho mob tshwj xeeb, xws li hydrophobic nto txheej, minimizes clumping hauv cov chaw noo noo.
Ya raws kev hloov kho:
Cov neeg lag luam feem ntau ntxiv cov neeg sawv cev xws li cov roj silicone kom txhim kho cov dej tsis kam ntxiv.
4. Thermal Decomposition Kev Ua Haujlwm
Tsim nyog decomposition kub:
Sodium Bicarbonate yuav tsum decompose tau zoo nyob rau ntawm 150-200 Qib kom tso cov dej thiab dej vapor sai sai rau hauv cov huab cua kub.
Siab decomposition efficiency:
Cov txheej txheem yuav tsum txo qis cov khoom seem dhau los kom tswj cov kev pab hluav taws kom zoo.
5. Tsis muaj tshuaj lom thiab muaj kev nyab xeeb ib puag ncig
Tsawg toxicity lossis tsis-toxicity:
Qhov sib xyaw yuav tsum muaj kev nyab xeeb rau tib neeg thiab ib puag ncig, nrog cov chaw seem ua rau tsis muaj kuab paug lossis lwm yam kev phom sij.
Ua raws li cov kev cai ib puag ncig:
Kev tsim khoom thiab siv tau yuav tsum ua kom raws li cov qauv ib puag ncig kom txo qis muaj peev xwm ntawm huab cua thiab av.
6. Cov Khoom Ntxiv
Anti-zoo li qub:
Hmoov sodium bicarbonate yuav tsim hluav taws xob zoo li qub thaum lub sijhawm tawm sai. Anti-cov khoom siv zoo li qub txo qhov kev pheej hmoo ntawm cov tawg ntawm theem nrab.
Kev kub heev:
Cov hmoov yuav tsum muaj kev nthuav qhia zoo heev rau kev faib tawm thiab cov tshuaj kom dim ntawm lub tua hluav taws.
