Puata wai Ihirangi ≥ 35%-55%
(Te whānuitanga o te tohutoro tono 'whakamahi hua')
He wairewa te hauwai pūkōwhai ki te wai, ā, ka kīia tōna wairewa wai ko te waikawa pūkōwhai.Ko te hua ko te nuinga 35% -50% hauwai pūkōwhai hau wairewa wai, te kukū teitei taea tae 75%, mo te wai paowa mārama kore tae.Ka hongi he kawa, he paoa, he auahi ma i te rangi.He waikawa pararopi te kaha waenga, he tino pirau, ka taea te waikura i te karaehe me te silicates hei hanga tetrafluoride silicon hau.Ka taea hoki te pahekoheko ki nga konganuku, nga waikura me nga waikura hei hanga i nga momo tai, engari kaore i te kaha te kaha ki te waikawa maaota.Kaore e taea e te koura, te konukawata, te mata, te paraffin me etahi kirihou te whakamahi, na reira ka taea te hanga ipu.Ko te hau hauwai hauwai he ngawari te polymerized ki te hanga (HF) 2 (HF) 3· ngota ngota homochain, a, i roto i te ahua wai, ka piki ake te tohu o te polymerization.Rokiroki ki roto i nga ipu i mahia ki te mata, te ware pi, te kirihou ranei.He tino paitini, ka taea te mate ki te pa ki te kiri.

Whakamahi Hua
Pikinga kirikiri kiripaka
He pai ake te mahi ina rongoahia ki te waikawa hydrofluoric, engari me nui ake te kukume.Ina tohaina ki te konutai disulfite, ka taea te whakamahi i nga kukū iti o te waikawa waiwaro.Ko tetahi kukū o te waikawa pūmāota me te wairewa waikawa pūhauwai i konatunatua ki te kumete kiripaka i te wa ano i runga i te rahinga;Ka taea hoki te rongoa ki te wairewa waikawa waikawa i te tuatahi, ka horoi katahi ka rongoa ki te waikawa hydrofluoric, ka rongoa ki te pāmahana teitei mo te 2-3 haora, ka tātarihia ka horoia, ka taea te tango i nga poke me nga waikura i runga i te mata o te kirikiri kiripaka me te whakapai ake. te ma me te kounga o te kirikiri kiripaka.
Te maimoatanga mata whakarewa
Tango i te mata o te hāora-kei roto poke, he waikawa ngoikore te waikawa waiwaro, he rite te kaha ki te waikawa formic.Ko te 30% ki te 50% te kukū nui o te waikawa hydrofluoric e waatea ana ki te hokohoko.Ko nga ahuatanga matua o te tango waikura waikawa hydrofluoric ko enei e whai ake nei:
(1) Ka taea te whakakore i nga pūhui kei roto i te silicon, te konumohe, te chromium me etahi atu waikura whakarewa he pai te whakarewatanga, e whakamahia ana ki te tarai i nga whakarewa, te kowiri tira me etahi atu mea mahi.
(2) Mo nga mea mahi maitai, ka taea te whakamahi i te waikawa hydrofluoric iti mo te tango waikura.Ko te wairewa waikawa Hydrofluoric me te 70% o te kukū he pānga hāngū ki runga maitai
(3) Ko te waikawa Hydrofluoric me te kukū o te 10% he ngoikore te paanga o te waikura ki runga i te konupora me ona koranu, no reira ka whakamahia i te nuinga o te waa ki te tarai i nga mea mahi konupora.
(4) Karekau te mata i te waikura e te waikawa waiwaro;He kaha te parenga a Nickel i roto i nga wairewa waikawa hydrofluoric he nui ake i te 60%.He tino paitini te waikawa Hydrofluoric, ka whakamahia ki te aukati i te pa ki te tangata ki te wai waikawa hydrofluoric me te hau hauwai fluoride, he pai rawa te hiri o te tank etching me te pai o te taputapu whakangao, a ka taea te tuku i te wai paru fluorinated.
Tukatuka graphite
Ko te waikawa waiwaro he waikawa kaha ka taea te tauhohe me nga mea poke katoa i roto i te kauwhata, a he pai te aukati waikawa o te kauwhata, ina koa ka taea te aukati i te waikawa waiwaro, e whakatau ana ka taea te purea te kauwhata ki te waikawa waiwaro.Ko te tukanga matua o te tikanga waikawa waiwaro ko te whakakotahi i te graphite me te waikawa hydrofluoric, me te tauhohe i te waikawa hydrofluoric me nga poke mo tetahi wa ki te whakaputa i nga matū wairewa ranei, i muri i te horoinga ki te tango i nga poke, te maroke me te whakamaroke ki te whiwhi graphite para.
He mea motuhake mo te keri whenua onge
Ko te tikanga whakarite o te pukoro onge whenua anhydrous ko te whakaheke i te pukoro o te whenua onge kua whakamakuku mai i te wairewa wai, katahi ka whakamakuku, ka whakakorikori ranei i te waikura whenua onge ki te maataki fluorinating.He iti rawa te whakarewatanga o te pukoro o te whenua onge, a ka taea te whakaheke mai i nga wairewa o te waiwaro, sulfuric, waikawa nitric ranei o te whenua onge ma te whakamahi i te waikawa puwhaoriki (ko te rerenga i te ahua o te fluoride hydrated).
TPT-LCD Mata angiangi (Koeke Hiko)
I raro i te whakamarumaru o te photoresist me te kāpia mata, ka whakatikahia te kukū o te waikawa hydrofluoric, te nui o te waikawa nitric, te waikawa sulfuric me te waikawa pūhaumāota ka taapirihia, ka taapirihia nga tikanga awhina ultrasonic, ka tino pai ake te tere o te etching.Ka taea te whakaiti i te taratara o te mata me te whakaheke i te rerenga o nga taapiri mata ma.Ka whakatauhia te raru o te mata taratara me te rerenga ma te adhesion o te mata.
Te waikura muka
Ko te waikawa Hydrofluoric ki tonu i te waikura te muka karaihe whakaahua (PCF).Ka whakakiia te waikawa Hydrofluoric ki roto i nga pores o te muka karaihe whakaahua totoro.Ma te whakarereke i te hanganga o te waahanga whiti, ka whakawhanakehia te muka karaihe photonic me te hanganga motuhake, ka whakarereketia te kawe oro.Ko nga hua e whakaatu ana ka heke te ngaronga rii me te mate marara me te pikinga o te tohu waikura porosity, ka tino piki ake te whakarea kore raina, ko te taupae whakaata whai hua o te pokepokea matua me te taupae whakaata rite o te kapi ka heke rite, me te marara o te roopu. ka huri ano.
