Dry upfu anodzima mumiririri:
Dry upfu moto ukabvisa mumiririri yakavhenganiswa nomoto anodzima chawo zvinhu (zvakadai kubika pasoda, Ammonium carbonate, Ammonium phosphate, etc.) uye zvakakodzera yakawanda mafuta (magnesium stearate, naMika upfu, talc upfu, etc.) uye shoma mwando-uchapupu mumiririri (silica gel). Zvakagadzirwa nezvimedu yakaisvonaka, kushandisa, carbon dioxide sezvo ndege simba.
Zvingakubatsira chiito:
Dry upfu moto ukabvisa nevasori zvinowa- inochengetwa yakaoma upfu moto kana yakaoma upfu moto ukabvisa michina. Munguva moto anodzima, yakaoma upfu iri vabudiswa kubva kamwene kubudikidza kwokudzvinyirira kwomunhu negasi carbon dioxide inobvisa kana senitrogen gasi kuumba pwititika upfu sorukova sandwiching ari negasi iyo chinotungamirwa kurutivi combustion chigadzirwa. Nheyo akatevedzana mumuviri nemakemikari pakati yakaoma upfu uye rimi riri sezvinotevera:
The yavaibvisa bicarbonate pakaoma upfu iri yaora nemupristi tembiricha. The kuita chinhu endothermic kuita. The kuita inongorira yakawanda carbon dioxide inobvisa uye mvura. Mvura neshungu kuva mvura mhute uye absorbs yakawanda kupisa, izvo anoita kuchitonhora uye sanganisa ari combustible gasi; wakaoma upfu anopinda womoto. Pashure paizvozvo, nokuda Absorção de Água uye kuputsanya akaoma upfu, kupisa nemwaranzi romurazvo kusvika mafuta ipfupi, uye kwemvura mwero nemvura iri ashaye.
Shijiazhuang Standard Chemicals Co., LTD unyanzvi iri kugadzirwa uye aina firefighting upfu, isu achakupa yepamusoro zvinhu uye basa kwazvo. Welcome vatengi kutaurirana.
