Kev Siv
Ammonium hydrogen difluoride yog ib yam khoom dawb crystalline uas muaj ntau yam kev siv hauv ntau yam lag luam. Cov hauv qab no yog kev qhia luv luv txog nws cov kev siv:
- Kev Lag Luam SemiconductorNws yog siv los ua tus neeg sawv cev etching rau semiconductor wafers thiab hauv kev tsim cov zaj duab xis nyias. Cov fluoride ions uas nws tso tawm pab hloov kho cov yam ntxwv ntawm cov khoom siv, uas yog qhov tseem ceeb rau kev ua cov khoom siv semiconductor kom raug.
- Kev Lag Luam IavNws ua haujlwm ua tus neeg sawv cev iav etching, feem ntau siv ua ke nrog hydrofluoric acid los txhim kho cov nyhuv etching. Nws kuj tseem siv tau rau kev kho qhov chaw ntawm silicon - steel ntawv, thiab koom nrog kev tsim cov iav tshwj xeeb, xws li iav uas tiv taus kub siab lossis tshuaj lom neeg tshwj xeeb.
- Kev Ua Hlau: Nws yog siv los ua cov kuab tshuaj rau cov hlau beryllium thiab hauv kev kho qhov chaw ntawm silicon - steel sheets. Hauv kev lag luam electroplating, nws tuaj yeem ua kom cov tshuaj tiv thaiv corrosion ntawm cov hlau nto, ua rau electroplating sib xws thiab ruaj khov dua.
- Tshuaj ReagentNws yog siv los ua cov tshuaj reagent hauv ntau yam tshuaj lom neeg thiab kev sim. Nws kuj tseem siv tau los npaj cov hlau fluorides los ntawm kev cuam tshuam nrog cov hlau oxides lossis cov hlau, thiab ua haujlwm ua qhov chaw tseem ceeb ntawm cov fluoride ions hauv ntau yam kev lag luam thiab kev siv tshuaj ntsuam xyuas.
- Lwm yam kev siv:Hauv kev lag luam tsim cov khoom siv ceramic thiab magnesium - alloy, nws ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim khoom. Nws kuj tseem siv rau kev ntxuav thiab tshem tawm cov nplai ntawm cov tshuab boiler pub dej thiab cov tshuab tsim pa, thiab hauv kev kho cov xuab zeb hauv cov roj av.
