WHAKAMAHI HUA
He wairewa te hauwai pūkōwhai ki te wai, ā, ka kīia tōna wairewa waiwaikawa pūhāwai.Ko te hua he maha 35% -50% wairewa wai o te hauwai pūkōwhai hau, te kukū teitei taea tae 75%, a ko te reira he tae kore, me te marama paipa wai.He kakara, he pahekeheke, he auahi ma i te rangi.He waikawa pararopi te kaha waenga, he tino pirau, ka taea te whakakore i te karaehe me te silicates hei whakaputa i te tetrafluoride silicon hau.Ka taea hoki te pahekoheko me nga konganuku, nga waikura me nga waikura hei hanga i nga momo tai, engari kaore i te kaha te paanga ki te waikawa maaota.Ko te koura, ko te konukawata, ko te mata, ko te parawini me etahi kirihou kare e mahi ki a ia, na reira ka taea te hanga ipu.He ngawari te hauwai pūkōwhai hauwai ki te polymerize, hanga (HF) 2 (HF) 3·· ngā rāpoi ngota iso-chain, i roto i te āhua wai, ka piki 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 mate ki te pa ki te kiri.
WHAKAMAHI HUA
KAUPAPA Ahumahi
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 atete ki te waikawa waiwaro, e whakatau ana ka taea te purea te graphite ki te waikawa waiwaro.Ko te tukanga matua o te tikanga waikawa hydrofluoric ko te ranunga o te graphite me te waikawa hydrofluoric, me te tauhohenga o te waikawa hydrofluoric me nga poke mo te 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.
Whenua onge kua whakatapua
Ko te whakaritenga o te pukoro onge whenua anhydrous na roto i te rerenga o te pukoro o te whenua onge kua whakamakuku mai i te wairewa wai, katahi ka whakamarokehia, ka whakamaarama tika ranei i nga waikura whenua onge me nga maakuku fluorinating.He iti rawa te whakarewatanga o te pukoro o te whenua onge, a ka taea e te whakamahi i te waikawa puwhaoriki te whakaheke mai i te waikawa maaota, te waikawa pungatara, te wairewa waikawa nitric ranei o te whenua onge (kei te ahua o te pukoro hydrated).
Te maimoatanga mata whakarewa
Tango i te mata o te hāora-kei roto i nga 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 waikura ko enei e whai ake nei: (1) Ka taea te whakakore i nga pūhui kei roto i te silicon, konumohe, chromium me etahi atu waikura whakarewa he pai te whakarewatanga, e whakamahia nuitia ana ki te tarai i nga whakarewa, te kowiri tira me etahi atu mea mahi.(2) Mo nga mea mahi rino me te rino, ka taea te whakamahi waikawa hydrofluoric iti mo te tango waikura.Ko te wairewa wai o te waikawa waiwaro me te kukū o te 70% he paanga o te paheketanga ki te rino (3) Ko te waikawa Hydrofluoric me te kukū o te 10% he ngoikore te waikura i runga i te konupora me ona koranu, no reira he maha nga wa e whakamahia ana mo 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%.Ko te waikawa Hydrofluoric he tino paitini, he puhoi, ina whakamahia hei aukati i te whakapiri tangata ki te wai waikawa hydrofluoric me te hauwai fluoride hau, he pai te hiri o te tank etching me te pai o te taputapu whakamahana, ka taea te whakakore i te wai paru fluorinated i muri i te maimoatanga.
Pikinga kirikiri kiripaka
He pai ake te mahi ina rongoa ki te waikawa waiwaro, engari me kaha ake te kukū.Ina tohaina ki te konutai dithionite, ka taea te whakamahi i nga kukū iti o te waikawa waiwaro.Ko tetahi kukū o te waikawa pūhaumāota me te wairewa waikawa pūhauwai i konatunatua ki roto i te slurry kiripaka 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, katahi ka tātarihia ka horoia Ka taea te tango tika i nga poke me nga waikura i runga i te mata o te kirikiri kiripaka, a ka taea te whakapai ake i te ma me te kounga o te kirikiri kiripaka.
Te waikura muka FOCS
I whakawhanakehia te waikura whakakī waikawa Hydrofluoric o te muka karaihe whakaahua (PCF).I whakakiia te waikawa waiwaro ki roto i te kohao hau o te muka karaihe whakaahua.Na roto i te whakarereke i tana hanganga waahanga ripeka, i whakawhanakehia te muka karaihe whakaahua me te hanganga motuhake hei whakarereke i tana kawe marama.Ko nga hua e whakaatu ana ka heke te ngaronga rii me te mate marara me te tohu pirau o te kohao hau o te muka karaihe photonic, ka tino piki te whakarea-kore, ko te taupae whakaata whai hua o te aratau matua me te taupae whakaata rite o te kapi ka heke rite, ka huri ano hoki te marara tere roopu.
KAUPAPA HIKO
TPT-LCD te angiangi mata
I raro i te whakamarumaru o te photoresist me te kapia rohe, ka whakatikahia te kukū o te waikawa hydrofluoric, te nui o te waikawa nitric, te waikawa sulfuric me te waikawa hauwai kua taapirihia, me te taapiri i nga tikanga awhina ultrasonic, kua tino pai ake te reeti etching.Ka tino whakahekehia te taratara o te mata ma te rereke o nga tikanga horoi, ka heke te rerenga o nga taapiri mata ma.Te whakaoti i te raruraru o te mata taratara me te ma ma te whakapiringa o te mata.
