Furfuryl mowa 98-00-0 mtengo wa fakitale
Pali katundu wokwanira, wapamwamba kwambiri komanso kutumiza mwachangu. Kuchuluka kochulukira ndi kuchotsera.
Zofunikira zilizonse, talandiridwa kuti mutilankhule nthawi iliyonse.

Kugwiritsa ntchito
【Gwiritsani ntchito imodzi】
Amagwiritsidwa ntchito ngati zopangira zopangira ma resin osiyanasiyana a furan, zokutira zotsutsana ndi dzimbiri, komanso zosungunulira zabwino.
【Gwiritsani ntchito ziwiri】
Ndiwosungunulira bwino komanso mafuta a rocket opangira ma resin, ma varnish ndi ma pigment. Itha kugwiritsidwanso ntchito popanga ulusi, mphira, mankhwala ophera tizilombo ndi mafakitale oyambira.
【Gwiritsani ntchito Atatu】
GB 2761-1997 imati ndizololedwa kugwiritsa ntchito zonunkhira zazakudya. Amagwiritsidwa ntchito kwambiri popanga zokometsera za coke.
【Gwiritsani ntchito zinayi】
Mowa wa Furfuryl umagwiritsidwa ntchito popanga organic synthesis, ndipo levulinic acid (chipatso cha acid) imapezeka ndi hydrolysis, yomwe ndi yapakati pamankhwala opatsa thanzi calcium fructate. Furan resins yokhala ndi zinthu zosiyanasiyana (monga furfuryl alcohol resins, furan I kapena furan II resins), furfuryl alcohol-urea-formaldehyde resins ndi phenolic resins zitha kukonzedwa kuchokera ku mowa wa furfuryl;
【Kagwiritsidwe 5】
Zosungunulira. organic synthesis (kupanga anthracene, utomoni, etc.). chosungira. zonunkhira.
Kusungirako
Iyenera kusindikizidwa ndikutetezedwa ku kuwala ndikusungidwa pamalo ozizira.
Pewani pafupi ndi asidi wamphamvu panthawi yosungira.
Khalani kutali ndi magwero a madzi, ndipo akhoza kusungidwa muzitsulo zachitsulo, zitsulo zofewa kapena aluminiyamu.
