Hydroxyl ann an glainne Quartz<\/strong><\/h2><\/div>\n\n\n\n

Canar hydroxyl ris an hydroxyl a chaidh a sgaoileadh ann an glainne quartz. Is e hydroxyl am pr\u00ecomh neo-chunbhalachd ann an glainne quartz, agus is e na pr\u00ecomh nithean a tha a\u2019 toirt buaidh air an t-susbaint aige stuthan amh, pr\u00f2iseasan agus d\u00f2ighean saothrachaidh. Leis gu bheil an susbaint hydroxyl ann an glainne quartz ag atharrachadh, tha coileanadh na glainne cuideachd ag atharrachadh. Tha \u00e0rdachadh susbaint hydroxyl a\u2019 leantainn gu l\u00f9ghdachadh ann an slaodachd, d\u00f9mhlachd, agus cl\u00e0r-amais ath-tharraing, agus \u00e0rdachadh ann an in-ghabhail infridhearg agus co-\u00e8ifeachd leudachaidh.<\/p>\n\n\n\n

St\u00e8idhichte air gi\u00f9lan hydroxyl ann an glainne quartz, faodar a roinn ann an d\u00e0 roinn: glainne quartz air a dh\u00e8anamh ann an \u00e0ile oxidizing agus glainne quartz air a leaghadh ann an \u00e0ile lughdachadh. Tha an hydroxyl anns a 'chiad fhear duilich a thoirt air falbh le teasachadh, fhad' sa tha e nas fhasa a thoirt air falbh anns an fhear mu dheireadh.<\/p>\n\n\n\n

Tha glainne quartz air a dh\u00e8anamh ann an \u00e0ile oxidizing a\u2019 toirt a-steach:<\/p>\n\n\n\n

    \n
  1. Glainne Quartz Synthetic<\/strong>: Tha silicon tetrachloride air a lobhadh gu teirmeach ann an lasair hydro-oxygen, le susbaint hydroxyl timcheall air 1000-2000 ppm.<\/li>\n\n\n\n
  2. Glainne Quartz air a ghrinneachadh le Gas<\/strong>: P\u00f9dar quartz air a leaghadh ann an lasair hydro-ogsaidean, le susbaint hydroxyl de 100-200 ppm.<\/li>\n\n\n\n
  3. Plasma Quartz Glass<\/strong>: P\u00f9dar quartz air a leaghadh ann an lasair plasma, le susbaint hydroxyl de 20-30 ppm.<\/li>\n\n\n\n
  4. Quartz ceangailte<\/strong>: P\u00f9dar quartz air a leaghadh ann an \u00e0ile \u00e8adhair, le susbaint hydroxyl de 300-500 ppm.<\/li>\n<\/ol>\n\n\n\n

    Tha e duilich an se\u00f2rsa seo de hydroxyl glainne quartz a thoirt air falbh le l\u00e0imhseachadh teas agus d\u00ecreach dehydroxylates ri fhaicinn os cionn an te\u00f2thachd criostalachaidh aig timcheall air 1350 ceum Celsius.<\/p>\n\n\n\n

    Glainne Quartz air a leaghadh ann an \u00e0rainneachd lughdachadh<\/strong>:<\/h2><\/div>\n\n\n\n

    Ann an \u00e0ile haidridean, tha an susbaint hydroxyl 100-200 ppm; faodaidh teasachadh os cionn 900 ceum Celsius a\u2019 mh\u00f2r-chuid den hydroxyl a thoirt air falbh. Ann an suidheachaidhean helium no falamh, tha an susbaint hydroxyl gu math \u00ecosal (fo 5 ppm).<\/p>\n\n\n\n

    Tha an hydroxyl ann an glainne quartz air a leaghadh ann an \u00e0ile hydrogen co-cheangailte ris na factaran a leanas:<\/p>\n\n\n\n

      Chan eil glainne quartz ath-leaghadh air a thoirt a-mach ann an \u00e0ile oxidizing ann an \u00e0ile haidridean a\u2019 sealltainn atharrachadh sam bith anns an st\u00f9c in-ghabhail hydroxyl aig 2.73 micron; tha seo a 'sealltainn nach e an te\u00f2thachd leaghaidh adhbhar an eadar-dhealachaidh ann an coileanadh dehydroxylation eadar an d\u00e0 she\u00f2rsa glainne.<\/p>\n\n\n\n

      Tha glainne quartz p\u00f9dar air a leaghadh ann an \u00e0ile oxidizing (meud gr\u00e0in 0.2-0.05mm) a\u2019 nochdadh atharrachadh m\u00f2r anns an st\u00f9c hydroxyl aig 2.73 micron \u00e0s deidh dha ath-leaghadh ann an \u00e0ile haidridean, ga dh\u00e8anamh nas fhasa hydroxyl a thoirt air falbh agus a choileanadh coltach ri quartz glainne air a leaghadh ann an \u00e0ile haidridean. Tha seo a\u2019 sealltainn gu bheil meud m\u00ecrean na fheart cudromach ann an eadar-dhealachaidhean dehydroxylation.<\/p>\n\n\n\n

      P\u00f9dar Glainne Quartz Hydroxyl \u00ccosal<\/strong> air ath-leaghadh ann an \u00e0ile haidridean a\u2019 meudachadh hydroxyl bho 3 ppm gu 100 ppm, a\u2019 nochdadh gum faod \u00e0ile hydrogen \u00e0rdachadh susbaint hydroxyl ann an glainne quartz. Tha blocaichean glainne quartz hydroxyl \u00ecosal air an ath-leaghadh ann an \u00e0ile haidridean a\u2019 nochdadh cha mh\u00f2r nach eil atharrachadh sam bith ann an susbaint hydroxyl (3 ppm), a\u2019 nochdadh gu bheil an eadar-obrachadh eadar hydrogen agus glainne quartz a\u2019 t\u00f2iseachadh aig an uachdar (\u00f9ine leaghaidh mu 30 mionaid).<\/p>\n\n\n\n
