Raws li Wildland Fire Chemical Systems (WFCS) ntawm Teb Chaws Asmeskas Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb, thaum siv cov thickeners rau hluav taws kub retardants kom dispersed aerially, guar gum tuaj yeem hloov cov kua rau hauv "pam" thiab ua kom nws tsis txhob evaporating hauv tshav kub lossis los ntawm raug cua tshuab ua ntej nws hits qhov chaw poob.
Muaj ob hom hluav taws kub retardants; xws li, cov uas thaum sib tov los yog diluted nrog dej kom kawg-siv concentration ua rau cov pos hniav thickened tov, thiab cov uas tsis muaj cov pos hniav thickener, xws li guar pos hniav hmoov, thiab ua rau cov dej-zoo li compounds.
Hluav taws kub retardant concentrates uas tau muab los ua kua los yog kua, xws li guar pos hniav hmoov, yog nyiam vim hais tias lawv tau yooj yim diluted nrog me ntsis sib tov, kho vajtse thiab / los yog manpower.
Thaum guar cov pos hniav ntxiv rau cov ntsiab lus ntawm cov hmoov qhuav thiab dej, nws hloov mus rau hauv ib qho condensed, viscous thiab elastic khoom uas txhim kho cov kua dej ntawm cov tshuaj tua hluav taws xaiv.
