Dry chemical fire extinguisher:
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab tua hluav taws no yog qhov yooj yim heev, nws tau ntim nrog ammonium phosphate qhuav hmoov hluav taws tua hluav taws, cov hmoov qhuav tua hluav taws yog ib qho tho txawv thiab yooj yim txav cov hmoov zoo siv los tua hluav taws, uas yog tsim los ntawm inorganic ntsev nrog hluav taws. extinguishing efficiency thiab ib tug me me ntawm qhuav hmoov tua hluav taws additives uas qhuav, crushed thiab sib tov rau hauv hmoov zoo.
CO2 hluav taws tua hluav taws:
Cov pa roj carbon dioxide tua hluav taws muaj keeb kwm ntawm ntau dua 1 {} txias rau cov pa hluav taws kub ua kom muaj hluav taws kub ua haujlwm tau muaj hluav taws kub siab, txog li 1.5 lub sij hawm uas ntawm huab cua. Ntawm atmospheric siab, kua carbon dioxide yuav vaporize tam sim ntawd, thiab feem ntau 1 kilogram kua carbon dioxide tuaj yeem tsim tau txog 0.5 cubic meters roj.
Foam tua hluav taws:
Raws li qhov xwm txheej ib txwm muaj, muaj ob lub thawv hauv lub tshuab tua hluav taws ua npuas dej, uas muaj ob lub kua, lawv yog txhuas sulfate thiab sodium bicarbonate tov, ob txoj kev daws teeb meem tsis sib cuag, thiab yuav tsis muaj tshuaj tiv thaiv, yog li nyob rau hauv dab tsi. xwm txheej lawv yuav muaj kev sib raug zoo?
Lo lus teb yog tias thaum hluav taws kub hnyiab tawm ib ncig ntawm peb thiab peb xav tau lub tshuab tua hluav taws ua npuas ncauj, peb siv nws, tig lub tshuab tua hluav taws ua npuas ncauj rov qab, thiab tom qab ntawd ob txoj kev daws teeb meem sib xyaw ua ke, thiab lawv kuj yuav muaj kev sib raug zoo, thiab tom qab ntawd. ntau cov pa roj carbon dioxide yuav raug tsim tawm, uas tuaj yeem ncav cuag cov txiaj ntsig ntawm kev tua hluav taws.
Alkyl halogen hluav taws tua hluav taws:
Halide tua hluav taws: Peb tsis hnov ntau txog lawv, txoj cai? Lub tshuab tua hluav taws zoo li cas no?
Cia peb saib nws, qhov no yog hais tias alkyl halides muaj qhov hnyav molecular loj, cov khoom siv tshuaj lom neeg ruaj khov, thiab tuaj yeem nyob rau ntawm qhov chaw ntawm qhov hluav taws kub thaum tua hluav taws, uas yog qhov yooj yim tshaj plaws rau cov nplaim taws, thiab alkyl halide molecule tuaj yeem tiv thaiv kev sib cuag ntawm combustion dawb radicals thiab cov pa oxygen hauv huab cua, thiab ncav cuag cov nyhuv ntawm cov tshuaj inhibition, thiaj li ua tiav cov nyhuv ntawm kev tua hluav taws.
Txawm li cas los xij, cov tshuaj tua hluav taws alkyl halide feem ntau kim dua, thiab nrog kev txhim kho ntawm tib neeg kev paub txog kev tiv thaiv ib puag ncig, alkyl halide hluav taws tua hluav taws tau raug txiav tawm.
Dej-raws li hluav taws tua hluav taws:
Lub hauv paus ntsiab lus ntawm kev tua hluav taws ntawm cov dej tua hluav taws yog lub cev hluav taws tua hluav taws, thiab tus neeg sawv cev tuaj yeem tsim thiab nthuav cov yeeb yaj kiab dej nyias ntawm cov nplaim hluav taws, kom cov hluav taws kub sib cais tuaj yeem raug cais tawm ntawm huab cua kom ua tiav cov txiaj ntsig ntawm hluav taws. tua hluav taws.
Cov dej tua hluav taws tua hluav taws tua cov dej tsis zoo los ntawm cov atomizing nozzle, kis cov hluav taws kub thiab evaporates cov cua sov, uas tuaj yeem txo qhov kub ntawm qhov hluav taws kub thiab txo qhov concentration ntawm oxygen nyob rau hauv cov huab cua nyob rau hauv combustion cheeb tsam kom tsis txhob. rov ignition.
