(Whaainga o te Tohutoro Tohutoro 'Te whakamahi hua')
Ko te hauwai hauwai te hau ka rewa i roto i te wai, me te otinga wai ka kiia ko te waikawa hydrofluoric. Ko te hua ko te 35% -50% te rongoa hau hauhake hau, ka taea e te tino kukume te 75%, mo te wai paowa paowa. Kakara kakara, he paowa, he paowa ma i te rangi. He momo waikawa harakore i te tino pai e tino pai ana ki te karaihe me te whakakii i te karaihe me te whakakikorua hei hanga i te silicon Tetraforide. Ka taea hoki te taunekeneke ki nga konganuku, te oxides whakarewa me te hydroxides hei hanga i nga momo tote, engari kaore i te kaha te paanga o te waikawa hydrochloric. He koura, ko te konukawata, te arahi, te paraffin me etahi o nga mea hangai kaore e taea te whakamahi, ka taea te hanga ipu. Ko te hauwai o te hauwai ka ngawari ki te hanga (HF) 2 (HF) 3 · HF) 3 · HF) 3 · HF) 3 · HF) 3 · HF) Rokiroki i roto i nga ipu i hangaia i te arahi, te riihi kirihou ranei. He tino paitini, ka taea te kuhu ki te whakapiri kiri.
Ko nga mea katoa e whakaratohia ana e Exprights®: Ihirangi / Whiteney / Parea / Phlvalingyle / Tae Atu me etahi atu hua motuhake.

Te whakamahi hua
Ko te taapara onepu Quartz
He pai te mahi i te wa e rongohia ana me te waikawa hydrofluoric, engari e hiahiatia ana nga kukume teitei ake. I te wa e tohatohahia ana ki te konutai i te konutai, ka taea te whakamahi i te waikawa o te waikawa hydrofluoric. Ko tetahi kukupa o te waikawa hydrochloric me te otinga waikawa waikawa hydrofluoric i whakaranuhia ki roto i te mokete Quartz i te wa ano i rite ki te rahi; Ka taea hoki te rongoa i te rongoa waikawa hydrochloric tuatahi, ka horoia ka rongohia ki te pāmahana hydrofluoric, ka tātarihia ki te mata o te onepu me te kounga o te onepu me te kounga o te onepu me te kounga o te onepu me te kounga o te onepu me te kounga o te onepu me te kounga o te onepu me te kounga o te onepu me te kounga o te onepu me te kounga o te onepu me te kounga o te onepu.
Maimoatanga whakarewa whakarewa
Tangohia te waikawa o te hau-kei roto i te poke, ko te waikawa hydrofluoric he waikawa ngoikore, he rite tonu ki te waikawa ahua. Ko te kukū whānui o te waikawa haukana e waatea ana i te waikawa e waatea ana i te waikawa te 30% ki te 50%. Ko nga ahuatanga matua o te tangohanga puehu waikawa waikawa e whai ake nei:
(1) Ka taea e te rewa te whakahiatotanga-kei roto, konumohe, te kromium me te kromium me etahi atu o nga oko whakarewa, he maha nga tikanga mo te kaimoana, he kowiri tira me etahi atu mahi.
(2) Mo nga mahi kowiri, ka taea te whakamahi i te waikawa hydrofluoric iti mo te tango puehu. Ko te otinga waikawa waikawa hydrofluoric me te 70% te kukume he mea kaha ki te kowiri
(3) Ko te waikawa hydrofluoric me te kukume o te 10% he painga ngoikore i runga i te konupora me ona taapiri, na reira e whakamahia ana i roto i te etchsic octium.
(4) Ko te arahi te nuinga kaore i te paihia e te waikawa hydrofluoric; He kaha te pawera o Nickel i roto i nga rongoā waikawa hydrofluoric me nga kukume nui ake i te 60%. Ko te waikawa hydrofluoric he tino paitini, he ngoikore hoki, ka whakamahia hei aukati i te waikawa o te tangata me te hauhautanga o te waikawa, a ka taea e te kaihoroi haangai.
Te tukatuka whakairoiro
Ko te waikawa hydrofluoric he waikawa kaha ka taea e te nuinga o te poke, me te whakairoiro waikawa, inaa ka taea te pure i te waikawa hydrofluoric. Ko te tikanga matua o te waikawa waikawa hardrofluoric ko te whakaranu i te whakairoiro me te waikawa hydrofluoric, me te ngoikore ki te tango i nga poke, i muri i te horoi i te poke.
Motuhake mo te keri whenua onge
Ko te tikanga whakarite o te anhydrous ao te rewharewha o te ao ko te whakaweto i te whenua onge mai i te otinga wai, ka rewa te totoka o te whenua onge. Ko te whakarewa o te rewharewha onge he iti rawa, a ka taea te heke mai i te hydrofluoric, he sulfuric, te waikawa waikawa nitric ranei o te waikawa o te hydrofluoric.
TPT-LCD te kiko o te mata (tohu hiko)
I raro i te tiakitanga o te photorestist me te paparanga o te mata, ka whakatikatikaina te waikawa o te waikawa me te waikawa hakihaki me te waikawa hydrochloric. Ko te Huringa Huringa ka taea te whakaiti i te ahua o te mata, ka whakaiti i te ua o nga taapiri ma. Ko te raru o te mata o te mata me te mata ma te ra ka whakatikahia.
Katihia te muka
Ko te waikawa hydrofluoric waikawa whakakiihia te muka karaihe crystal crystal (pcf). Ka whakakiia te waikawa hydrofluoric ki nga pores o te muka karaihe eturuturu ana. Ma te huri i tana hanganga waahanga ripeka, ka whakawhanakehia te muka karaihe whakaahua me te hanganga motuhake me te whakarereke i tana whanonga. Ko nga hua e whakaatu ana ko te ngaro o te riihi me te horapa i te heke o te tohu o te kaupapa porangi, ko te tohu ngoikore o te kohinga o te roopu.
