Kagwiritsidwe Ntchito
Ammonium hydrogen difluoride ndi kristalo yoyera yolimba yomwe imagwiritsidwa ntchito mosiyanasiyana m'mafakitale osiyanasiyana. Izi ndi mwachidule zomwe zikufotokozera momwe imagwiritsidwira ntchito:
- Makampani Opanga Makontrakitala: Imagwiritsidwa ntchito ngati choyeretsera cha ma wafer a semiconductor komanso popanga mafilimu opyapyala. Ma ion a fluoride omwe imatulutsa amathandiza kusintha mawonekedwe a pamwamba pa zipangizo, zomwe ndizofunikira kwambiri pakugwiritsa ntchito bwino zida za semiconductor.
- Makampani Opanga Magalasi: Imagwira ntchito ngati chotsukira magalasi, nthawi zambiri imagwiritsidwa ntchito limodzi ndi hydrofluoric acid kuti iwonjezere mphamvu yotsukira. Ingagwiritsidwenso ntchito pochiza pamwamba pa mapepala achitsulo a silicon, ndipo imagwiritsidwa ntchito popanga magalasi apadera, monga magalasi olimbana ndi kutentha kwambiri kapena mankhwala enaake.
- Kukonza Zitsulo: Imagwiritsidwa ntchito ngati chosungunulira chachitsulo cha beryllium komanso pochiza pamwamba pa mapepala achitsulo a silicon. Mu makampani opanga ma electroplating, imatha kufulumizitsa kupangika kwa dzimbiri pamwamba pa chitsulo, zomwe zimapangitsa kuti ma electroplating akhale ofanana komanso olimba.
- Chothandizira Mankhwala: Imagwiritsidwa ntchito ngati chothandizira cha mankhwala m'machitidwe osiyanasiyana a mankhwala ndi zoyeserera. Ingagwiritsidwenso ntchito kukonza ma fluoride achitsulo pochita ndi ma oxide achitsulo kapena zitsulo, ndipo imagwiritsidwa ntchito ngati gwero lofunika la ma ayoni a fluoride m'mafakitale ambiri komanso m'magawo ofufuza.
- Ntchito Zina:Mu mafakitale opanga zinthu zopangidwa ndi ceramic ndi magnesium - alloy, imagwira ntchito yofunika kwambiri popanga zinthu. Imagwiritsidwanso ntchito poyeretsa ndi kuchotsa ma scaling a boiler - makina amadzi ndi makina opangira nthunzi, komanso pochiza mafuta - miyala yamchenga.
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.
