Waikawa hydrofluoric

Kei te maha hua waikawa Hydrofluoric i te puka o te otinga 40%, engari i ētahi wā puta noa 50% ranei 72% rongoā. Otiia huaina reira ko te waikawa hydrofluoric pūkōwhai hauwai wai ranei. i hanga tona ingoa i te taha o fluorspar, i nei, i roto i te tahuri, he hauwai pūkōwhai.

waikawa Hydrofluoric - tona HF tātai. Whatu, he mea he wai te huitahi, kua he taimaha o rāpoi 20,0063 g / mol me te kiato - 1.15 g / cm³. Kei te āhuatanga i te reira na roto i te pāmahana: te rewanga - 83,6 ° C, te kohua - 19,5 ° C. Ko reira kore-pūkākā, me te tino paitini.

He aha ngā āhuatanga e te waikawa hydrofluoric? Ko te tātai o tenei rauemi kōrero e ngā hau köwhai me te hauwai i roto i tona hanganga. No te reira ki te piha haapiiraa tuarua o te ati, rite i hanga e te dissociation o köwhai he paitini, me te mōrearea ki to tatou taiao.

Ki runga ki te whakakāhoretanga o te waikawa i roto i te wai i roto i te nui o te wera, ko te 59.1 kJ / mol. tauhohe te reira ki konganuku maha, reira hanga fluorides. Interesting Ko te meka e he ahei o tukupu te pūwāhi mīti o te paerewa wai noa te wahi iti o tenei waikawa. I iti pūkōwhai pāmahana hauwai te pūhui e whai ake nei ki te H2O wai · HF, H2O ko H2O · 2HF · 4HF.

Ahakoa te meka e no te waikawa hydrofluoric ki waikawa kaha reo, corrodes reira me te ipu karaihe magnesium. I tua atu, ko reira anake te tetahi o ona taonga piha e tauhohe ki silicon waikura SiO (2). Tenei waikura, i roto i te tahuri, ko te rauemi matua whakamahia mō te hanga karaihe. waikawa Hydrofluoric e kore pānga i runga i te ware pi, na te whānui whakamahia reira mo tona rokiroki. I te wa hakari kua kawea reira, ka rongoa anake i roto i te mōkihi kirihou, ranei hanga o rapa me ngā ārahi. kia kawea ai kukū High (60%) waikawa i roto i te ipu kaha i hanga o te rino.

Konganuku, e kore e wairewa i roto reira e, arahina reira, konukawata me te koura. Kei waikawa hydrofluoric hangarau e rave rahi poke, i roto i nei te noa tino e pērā i Fe, RB, rite, ko N2SiF6, SO2. whiwhi waikawa horoi pai e tahuri i te reira ki te pāhare pāporo difluoride. I tua atu, kua decomposed reira, ka rewa e te para i te pūkōwhai hauwai i roto i te wai.

A, no te mahi i roto i te taiwhanga whakamahi oko, me ipu o te polyethylene me PTFE, me ngā pukapuka nui o te waikawa hydrofluoric penapena i roto i te maitai, raru, tāke hermetically kati, me tāke ranei ipurau momo haukini, e hiahiatia ana e te ki te whai i te tae tiaki e wātea ana.

He mōrearea ki te hauora tangata waikawa Hydrofluoric. He ia he pānga whakapōauau ngoikore i runga i te konä. Ki te whakatika ia mo etahi take ki te toto, i roto i tenei take ki te karo poisoning kino ki te huringa i roto i te mahi o te pūnaha kūnatu me te edema pūkahukahu. Ka taea e Ahakoa waikawa hydrofluoric whakapōrearea i mahi ngakau, me te haurangi whānui o te rauropi.

I roto i te whakapā ki te kiri kanohi ranei, ai reira weranga fakamamahi noa i nohanga iti. Rawa nunu'a kino o te penetration waikawa i whao, na te mahi ki a reira Me anake ki te kakahu karapu me te totoro pai.

Ki te, ahakoa, ka waikawa te kiri, na hohoro horoia reira ki te wai rere, ka hamani ki 2.5% gluconate konupūmā rite te rā. Otiia e kore e taea e mutu, kia kōrero koe ki tō tākuta tonu. Ka whakarite ia i te werohanga rō-uaua o te konupūmā pūhaumāota.

whakamahia hea te tenei waikawa kino? I tēnei wā, kei te kaha te whakamahia te reira i roto i te kore kamaka o magnesium ki tareka konganuku pērā i Niobium, tantalum me te zirconium. E ohipa te reira te whakakōkī mō te hydrogenation me dehydrogenation, me rite i roto i te hanga o fluoropolymers, freons me te waikawa fluorosulfonic. kitea ia tona tono i roto i te ahumahi hinu. i tukinotia ia ki puna hinu ki te whakarei ake te hinu production.
