Kufotokozera:
Dehydroacetic acid ndi chinthu chochokera ku pyrone, chomwe nthawi zambiri chimapangidwa ndi diketene yomwe imayambitsa kusungunuka kwa madzi. Imagwiritsidwa ntchito ngati chosungira mu mankhwala, chakudya, ndi zinthu zodzikongoletsera.
Miyezo yachiwiri ya mankhwala yogwiritsidwa ntchito poyang'anira khalidwe, imapatsa ma labotale opanga mankhwala ndi opanga njira ina yabwino komanso yotsika mtengo m'malo mokonzekera miyezo yogwirira ntchito mkati.

Kagwiritsidwe Ntchito
Dehydroacetic acid (DHS) imagwiritsidwa ntchito ngati chokhazikika pa zinthu zokongoletsa ndi zamankhwala chifukwa cha ntchito yake yowononga mabakiteriya ndi mabakiteriya, monga chowonjezera pa zinthu zokhazikika za PVC komanso popanga mankhwala a ziweto.
Chosungira cha Geogard(R) 111a chimachokera ku dehydroacetic acid (DHA) ndipo motero chimadziwika ndi akuluakulu oyang'anira zodzoladzola, zimbudzi ndi zonunkhira padziko lonse lapansi kuti chimagwiritsidwa ntchito popanga zodzoladzola ndi zosamalira thupi.
Chosungira cha Geogard(R) 221 chimachokera ku dehydroacetic acid (DHA) ndi benzyl alcohol, motero chimadziwika ndi akuluakulu oyang'anira zodzoladzola, zimbudzi ndi zonunkhira padziko lonse lapansi kuti chimagwiritsidwa ntchito pazinthu zodzikongoletsera komanso zosamalira thupi.
Chosungira cha Geogard(R) 361 chimachokera ku zigawo zisanu ndi chimodzi zogwirizanitsa, zonse zomwe zimavomerezedwa padziko lonse lapansi: dehydroacetic acid (DHA); salicylic acid; benzoic acid; phenoxyethanol; benzyl alcohol; ndi benzethonium chloride.
mankhwala opha mabakiteriya, opha mabakiteriya
Asidi ya dehydroacetic ndi mankhwala osungira omwe ali ndi mphamvu yochepa yochepetsera kuuma kwa khungu. Ichi ndi asidi wofooka yemwe amagwiritsidwa ntchito ngati mankhwala owononga bowa ndi mabakiteriya mu zodzoladzola. Kupezeka kwa zinthu zachilengedwe kumachepetsa mphamvu yake. Sizimayambitsa kuyabwa kapena ziwengo zikagwiritsidwa ntchito pakhungu.
Dehydroacetic Acid (DHA) ndi mankhwala osungira omwe ndi ufa wa kristalo wokhala ndi kusungunuka kosakwana 0.1 g mu 100 g ya madzi pa 25°C. Amatha kuchitidwa zinthu zosiyanasiyana zomwe zimapangitsa kuti agwiritsidwe ntchito m'njira zambiri. Amagwiritsidwa ntchito pa 0.01–0.5% poletsa kukula kwa tizilombo toyambitsa matenda muzakudya zosiyanasiyana. Amagwiritsidwa ntchito pa sikwashi yodulidwa kapena yodulidwa, ndipo osapitirira 65 ppm yotsala mu sikwashi yokonzedwa kapena pa sikwashi yokonzedwa.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
