Ukusetyenziswa
I-Ammonium hydrogen difluoride sisixhobo esimhlophe esiqinileyo esisetyenziswa ngeendlela ezahlukeneyo kumashishini ahlukeneyo. Oku kulandelayo sisishwankathelo esifutshane sokusetyenziswa kwaso:
- Ishishini leSemiconductorIsetyenziswa njenge-etching agent kwii-semiconductor wafers nakwimveliso yeefilimu ezincinci. Ii-ion ze-fluoride ezikhuphayo zinceda ekutshintsheni iimpawu zomphezulu wezinto, nto leyo ibalulekileyo ekucutshungulweni ngokuchanekileyo kwezixhobo ze-semiconductor.
- Ishishini leglasi: Isebenza njengearhente yokugrumba iglasi, edla ngokusetyenziswa kunye ne-hydrofluoric acid ukuphucula isiphumo sokugrumba. Ingasetyenziselwa unyango lomphezulu wee-silicon - steel sheets, kwaye ibandakanyeka kwimveliso yeglasi ekhethekileyo, njengeglasi enokumelana nobushushu obuphezulu okanye i-chemical reactivity ethile.
- Ukucubungula isinyithiIsetyenziswa njengesinyibilikisi se-beryllium yesinyithi kunye nonyango lomphezulu weeshiti zesinyithi ze-silicon. Kwishishini le-electroplating, inokukhawulezisa ukusabela kokugqwala kumphezulu wesinyithi, okwenza i-electroplating ifane kwaye iqine ngakumbi.
- I-Reagent yeKhemikhali: Isetyenziswa njenge-reagent yeekhemikhali kwiimpendulo ezahlukeneyo zeekhemikhali kunye novavanyo. Ingasetyenziselwa nokulungisa ii-fluoride zesinyithi ngokuphendula ngee-oxide zesinyithi okanye iimetali, kwaye isebenza njengomthombo ophambili wee-ion ze-fluoride kwizicelo ezininzi zoshishino kunye nohlalutyo.
- Ezinye iindlela zokusetyenziswa:Kwimizi-mveliso ye-ceramic kunye ne-magnesium-alloy, idlala indima ebalulekileyo kwinkqubo yemveliso. Ikwasetyenziselwa ukucoca kunye nokususa ii-scales ze-boiler feed - iinkqubo zamanzi kunye neenkqubo zokuvelisa umphunga, kunye nonyango lwe-oyile-field sandstones.
Ukupakishwa kunye nokuthunyelwa
25KG/Idrama okanye ngokweemfuno zomthengi.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
