Thaum lub sijhawm ua haujlwm txhua hnub ntawm cov hmoov sib tov, cov neeg ua haujlwm yuav ntsib cov lus nug tsis meej no:
Vim li cas qee cov hmoov thiaj sib tov tau zoo thiab ua tau zoo, thaum lwm cov yuav tsum tau tswj qhov kub thiab av noo kom nruj? Qhov no feem ntau yog los ntawm lub tswv yim tseem ceeb uas yooj yim tsis meej pem—"hmoov qhuav" piv rau "hmoov tshuaj qhuav."Txawm hais tias ob qho tib si zoo li hmoov qhuav, los ntawm qhov kev xav ntawm cov ntaub ntawv tshawb fawb nruj, lawv muaj qhov sib txawv tseem ceeb.
I. Cov Lus Txhais
"Hmoov qhuav" yog ib lo lus dav dav uas hais txog cov khoom siv raw hauv kev lag luam. Hauv kev lag luam thiab kev siv tshuab hmoov, nws hais txog txhua yam khoom siv uas muaj nyob rau hauv daim ntawv ntawm cov khoom qhuav.
Cov ntaub ntawv zoo li no pom muaj ntau hauv kev tsim khoom lag luam txhua hnub, xws li hmoov nplej thiab mis hmoov hauv kev lag luam zaub mov, hmoov tshuaj, nrog rau cov xim thiab cov khoom sau hauv kev lag luam tshuaj lom neeg.
Los ntawm qhov kev xav ntawm cov hmoov sib tov, lub hom phiaj tseem ceeb hauv kev ua cov "hmoov qhuav" no feem ntau yog ua kom tiavkev sib xyaw ua ke ntawm lub cevCov kws ua haujlwm sib tov feem ntau tsom mus rau cov yam xws li kev faib tawm qhov loj me ntawm cov khoom me me, cov qauv ntawm cov khoom me me, qhov ceev, thiab kev ntws kom ntseeg tau tias cov khoom sib txawv tsis sib cais tom qab sib tov.
Qhov sib txawv, "hmoov tshuaj qhuav" yog lub tswv yim tshwj xeeb dua thiab txhais tau nqaim dua nrog kev ua haujlwm tshuaj lom neeg thiab kev ua haujlwm meej.
Hauv kev ua haujlwm ntawm kev tsim kho thiab kev nyab xeeb hluav taws, lo lus no txhais tau hais tias yog ib pawg ntawm cov hmoov tsim uas tsim los ntawm cov tshuaj tshwj xeeb. Lawv tsis yog cov khoom siv xwb, tab sis kuj yog cov tshuaj ua haujlwm nrog cov hom phiaj tshuaj tshwj xeeb.
Feem ntau lawv siv ua cov tshuaj tua hluav taws. Piv txwv li, ABC cov hmoov tshuaj qhuav feem ntau yog ua los ntawm ammonium phosphate, thaum BC cov hmoov tshuaj qhuav feem ntau yog ua los ntawm sodium bicarbonate. Cov hmoov no yog tsim los kom dhau los ua cov tshuaj lom neeg hauv qab cov xwm txheej tshwj xeeb (xws li raug hluav taws) kom tiv thaiv kev kub hnyiab.
II. Qhov sib txawv ntawm Kev Ua Haujlwm Tov Khoom
Rau cov hmoov qhuav ib txwm muaj, lub luag haujlwm tseem ceeb ntawm lub tshuab sib tov yog los daws teeb meemkev sib xyaw ua ke ntawm lub cev.
Cov neeg ua haujlwm yuav tsum tau kho qhov ceev thiab lub sijhawm sib tov raws li cov khoom siv xws li lub kaum sab xis ntawm kev so thiab qhov ceev ntawm cov khoom, kom tiv thaiv kev faib ua pawg tom qab sib tov. Lub hom phiaj yog kom ua tiav lub cev "homogeneity."
Tag nrho cov txheej txheem no yooj ywm heev. Txawm hais tias tseem yuav tsum xav txog kev huv ntawm ib puag ncig, qhov kub thiab txias, thiab av noo, feem ntau tsis muaj kev pheej hmoo loj ntawm cov tshuaj lom neeg.
Txawm li cas los xij, rau cov hmoov tshuaj qhuav, cov teeb meem hauv kev sib tov hloov mus raukev ruaj khov tshuaj lom neeg thiab kev ua kom raug.
Thaum ua cov hmoov no, lub hom phiaj tsis yog tsuas yog sib tov xwb, tab sis kuj yog:
● tiv thaiv kev ua tshuaj lom neeg tsis xav tau
● xyuas kom meej cov qauv sib piv
● tswj kev ua haujlwm kom ruaj khov
Piv txwv li, hauv kev tsim cov hmoov tua hluav taws, qhov sib piv ntawm ammonium phosphate rau cov khoom ntxiv yuav tsum raug heev. Txawm tias qhov sib txawv me me hauv cov khoom sib xyaw kuj tseem yuav txo qhov kev ua haujlwm tua hluav taws lossis ua rau cov khoom tsis zoo.
Ntxiv rau, cov hmoov no feem ntau hygroscopic thiab tej zaum yuav muaj qee yam corrosive lossis irritant zog. Yog li ntawd, cov tshuab sib tov yuav tsum tau nruab nrog:
● Cov txheej txheem kaw plua plav thiab tiv thaiv kom tsis txhob xau zoo
● cov txheej txheem tiv thaiv roj inert (thaum xav tau)
● cov tshuab tswj kub kom txo tau cua sov uas tsim los ntawm kev sib txhuam thaum lub sijhawm sib tov
Cov kev ntsuas no pab tiv thaiv kom tsis txhob lo, puas tsuaj, lossis xeb ntawm cov khoom siv thaum lub sijhawm ua haujlwm.
III. Cov Cheeb Tsam Siv
Qhov sib txawv no pom tseeb tshwj xeeb hauv cov ntawv thov tua hluav taws.
Hauv cov qauv thoob ntiaj teb xws li NFPA kev faib tawm, "hmoov qhuav" feem ntau yog siv los hais txog cov tshuaj tua hluav taws tshwj xeeb rau cov hluav taws hlau Class D, thaum "hmoov tshuaj qhuav" feem ntau yog hais txog cov tshuaj tua hluav taws ntau yam rau cov hluav taws Class A, B, thiab C.
Txawm li cas los xij, hauv kev lag luam thiab txhua hnub, vim tias ABC cov hmoov tshuaj qhuav yog cov siv dav tshaj plaws, ob lo lus no feem ntau siv sib pauv.
Txawm li cas los xij, txawm tias cov lus sib txawv li cas los xij, lub hauv paus ntsiab lus tseem zoo ib yam:
Hmoov tshuaj qhuav yog cov khoom siv ua haujlwm uas tsim los rau cov hom phiaj tshuaj tshwj xeeb, thaum cov hmoov qhuav ib txwm yog cov khoom siv raw siv rau kev sib tov.
