Rangahau Taiwhanga me te Pūtaiao

E whakamahia ana i roto i ngā tauhohenga matū pāmahana-tiketike, ngā ngongo korehau me ngā pūnaha whakatakotoranga kohu matū (CVD), he pai mō ngā taiao whakamātautau uaua pēnei i te waikura waikawa kaha me te pyrolysis pāmahana-tiketike.
Ahumahi muka whatu me te hikohiko whatu

Hei ringaringa tiaki me ngā pokepokea tuhi i roto i te hanga muka whatu, hei whakarite i te parakore me te ōritetanga o ngā rauemi muka whatu i te wā o te tukanga tuhi pāmahana-tiketike.
Te Tiaki Taiao me te Maimoatanga Para

Whakamahia ana i roto i ngā tahunga hau para pāmahana teitei me ngā taputapu maimoatanga para kino, e whakamahi ana i tō rātou ātete pāmahana teitei me te pumau matū hei wawahi i ngā matū kino.

Ngā Pātai Auau

Q He aha te pāmahana mahi mōrahi o te karāhe kuata kua hanumi?

Ka taea e te karāhe quartz hanumi te tu atu i te pāmahana whakamahinga poto tae atu ki te 1300 °C me te pāmahana whakamahinga tonu mo te wā roa tae atu ki te 1100 °C. Ko tōna pāmahana tukatuka wera kei waenga i te 1750 °C ki te 2050 °C, koia tētahi o ngā rauemi karāhe tino pumau ki te wera e wātea ana.

Q He aha i iti ai te tauwehenga whānui wera o te karāhe kuata kua hanumi?

Ko te tauwehenga whakawhanui wera tino iti o te 5.5 × 10⁻⁷ cm/cm·°C he hua nō tōna hanganga hauhā silicon amorphous (SiO₂). Mā tēnei āhuatanga ka ātete pai te kuata hanumi ki ngā ru wera, ka taea ai e ia te tu atu ki ngā huringa pāmahana tere me te kore e pakaru.

Q He aha te tikanga o te tohu PPM mō te karāhe quartz, ā, he aha te hiranga o tēnei?

Ko te taumata PPM (ngā wāhanga ia miriona) e pā ana ki te taumata o te poke whakarewa i roto i te karāhe quartz. Kei te wātea i roto i ngā taumata whakahaere o te 10, 20, me te 100 PPM, ko ngā uara PPM iti e tohu ana i te parakore teitei ake, he mea nui mō ngā tono ahumahi semiconductor, optical, me te tino tika e tika ana kia whakaitihia te poke.

Q He aha ngā kōwhiringa matotoru e wātea ana mō te karāhe quartz?

Kei te wātea te karāhe kuata i roto i ngā matotoru mai i te 2 mm ki te 20 mm. Nā te āhua porohita me te whānuitanga o te matotoru, he tino whai hua mō ngā mahi ahumahi, taiwhanga, me te tirohanga.

Q He pēhea te whakataurite i te kaha pēhi o te kuata hanumi ki tōna kaha piko?

He tino kaha te kaha pēhi o te kuata hanumi, arā, 1100 MPa, ā, he tino ātete ki ngā kaha pēhi. Heoi, he iti ake tōna kaha piko (he kaha piko) i te 67 MPa, he mea noa tēnei mō ngā rauemi karāhe. Ko te tikanga, he pai ake te mahi a te karāhe kuata i ngā tono e whakamahia ana ngā kawenga pēhi, kaua ko ngā kawenga piko.

Q He rite tonu te karāhe quartz hanumi ki te karāhe noa?

Kāo. He mea hanga te karāhe kuata hanumi mai i te Silicon Dioxide parakore (kuata tūturu) ā, he rerekē rawa atu i te karāhe houra-raima paerewa. He pai ake te ātete wera, he iti ake te tauwehenga whānui wera, he teitei ake te parakore, ā, he mārama ake te whatu - inā koa i roto i ngā roangaru UV - e pai ai mō ngā taiao pūtaiao me ngā taiao ahumahi uaua.

Tākai me te Tukunga

He aha i whiriwhiri ai Te Kuata ki te Tonga-mā-rāwhiti?

E whakawhirinaki ana a Southeast Quartz ki ngā rauemi kohatu quartz kounga teitei i te takiwa o Donghai, e whai wāhi nui ana ki te tukatuka hohonu i te karāhe quartz, ā, kua noho hei kaiwhakarato matua ki ngā kiritaki o te ao. He maha ngā whakamātautau mō ngā hua katoa, pērā i te kimi turuturu i te inenga papatipu helium, te whakamātautau ātete pēhanga, me te whakamātautau parakore i mua i te wehenga atu i te wheketere kia mau ai te mahi, kia kore ai he poke, kia kore ai hoki he turuturu.
