Ngā pepa karāhe kuata JGS1 JGS2 JGS3

Whakaahuatanga Poto:

Ko ngā rau karāhe kuata, e mōhiotia ana ko ngā pereti silica kua hanumi, ko ngā pereti kuata rānei, he rauemi tino motuhake i hangaia mai i te hauhā silicon (SiO₂) tino parakore. E whakanuia ana ēnei rau mārama, pakari hoki mō tō rātou māramatanga whatu tino pai, te ātete ki te wera, me te pumau matū. Nā ō rātou āhuatanga pai, e whakamahia whānuitia ana ngā rau karāhe kuata puta noa i ngā ahumahi maha, tae atu ki ngā semiconductors, ngā whatu, ngā photonics, te pūngao o te rā, te whakarewa, me ngā tono taiwhanga matatau.

He Tirohanga Whānui mō te Karāhe Quartz

Ka hangaia ā mātou pepa karaihe kuata mā te whakamahi i ngā rauemi mata kounga teitei pērā i te tioata tūturu, te silica hangai rānei, ka tukatukahia mā roto i ngā tikanga rewa me te oro tika. Ko te hua he mata tino papatahi, he iti te poke, ā, kāore he mirumiru e tutuki ana i ngā whakaritenga tino pakari o ngā tukanga ahumahi hou.

Ngā Āhuatanga Matua o ngā Pepa Karāhe Quartz

Ātete Wera Tino Nui
Ka taea e ngā pepa karāhe kuata te tu atu i ngā pāmahana tae atu ki te 1100°C i te whakamahinga tonu, ā, ka teitei ake anō hoki i ngā wā poto. Nā te iti rawa o te tauwehenga whānui wera (~5.5 × 10⁻⁷ /°C) ka tino ātete ki ngā ru wera.
Teitei o te Māramatanga Whatu
He tino mārama te hihi UV, te hihi e kitea ana, me te hihi IR i runga i te momo, ā, neke atu i te 90% ngā tere tuku i te nuinga o ngā awhe e kitea ana. Nā tēnei ka tino pai mō te whakaahua me te whakamahi i te taiaho.
Te Pumautanga Matū
Kāore te karaihe kuata e ātete ki te nuinga o ngā waikawa, ngā kawakore, me ngā hau waikura. He mea nui tēnei ātete mō ngā taiao rūma ma me te tukatuka matū parakore teitei.
Te Kaha me te Pakari o te Mīhini
Ahakoa te pakeke o te karaihe kuata i waenga i te 6.5–7 me te Mohs, he pai te ātete ki te rakuraku me te pumau o te hanganga o ngā rau karāhe kuata, ahakoa i raro i ngā āhuatanga uaua.
Te Ārai Hiko
He ārai hiko pai rawa atu te kuata, ā, e whakamahia whānuitia ana i roto i ngā tono auau teitei me te ngaohiko teitei nā te mea he iti tōna pūmau dielectric me tōna ātete teitei.

Jgs1 Jgs2 Jgs3 Pereti Karāhe Kuata Porowhita Pereti Hiraka Whakakotahi Irahiko Whakaahua

He maha ngā wā ka whakarōpūtia te karāhe kuata eJGS1, JGS2, meJGS3ngā momo, e whakamahia whānuitia ana i ngā mākete ā-rohe me ngā mākete kaweake:

JGS1 – Hiraka Whakakotahitia o te Karaehe Whatu UV

Te tuku UV teitei(ki raro ki te 185 nm)
Rauemi hangai, iti te poke
Whakamahia i roto i ngā tono UV hōhonu, ngā taiaho UV, me ngā whatu tika

JGS2 – Kuata Whero me te Karaehe Kitea

He pai te IR me te tuku kitea, te tuku UV ngoikore i raro i te 260 nm
He iti ake te utu i te JGS1
He pai mō ngā matapihi IR, ngā tauranga tirohanga, me ngā taputapu whatu kore-UV

JGS3 – Karāhe Kuata Ahumahi Whānui

Kei roto ko te quartz hanumi me te silica hanumi taketake
I whakamahia i roto ingā whakamahinga whānui o te pāmahana teitei, o te matū rānei
He kōwhiringa utu-whai hua mō ngā hiahia kore-whatu

Ngā Pātai Auau mō ngā Mōhiti Quartz

P1: He aha te rerekētanga i waenga i te quartz kua hanumi me te silica kua hanumi?
A:Ka hangaia te kuata hanumi mai i te tioata kuata tūturu kua rewa i te pāmahana teitei, ko te silica hanumi ka hangaia mai i ngā matū silicon parakore-teitei mā te whakatakotoranga kohu matū, te hydrolysis rānei. Ko te silica hanumi he nui ake te parakore, he pai ake te tuku UV, ā, he iti ake te ihirangi poke i te kuata hanumi.

Q2: Ka taea e ngā pepa karāhe quartz te tu atu i ngā pāmahana tiketike?
A:Āe. He tino pai te pumau o ngā rau karāhe kuata ki te pāmahana, ā, ka taea te mahi tonu i ngā pāmahana tae atu ki te 1100°C, me te ātete poto tae atu ki te 1300°C. He tino iti hoki te horapa wera, ā, he tino ātete ki te ru wera.

Q3: He ātete ngā rau karāhe kuata ki ngā matū?
A:He tino ātete te kuata ki te nuinga o ngā waikawa, tae atu ki ngā waikawa hauwaiora, hauota, me te whanariki, tae atu ki ngā whakarewa waro. Heoi, ka taea te whakaeke e te waikawa hauwaiora me ngā otinga kawakore kaha pērā i te hauwaiora konutai.

Q4: Ka taea e au te tapahi, te keri rānei i ngā pepa karāhe kuata māku ake?
A:Kāore mātou e tūtohu kia mahi mīhini-ā-ringa. He pakarukaru, he mārō hoki te kuata, ā, me whakamahi taputapu taimana me ngā taputapu CNC ngaio, taputapu laser rānei mō te tapahi, te keri rānei. Mēnā kāore i te tika te whakahaere, ka pakaru pea, ka hē rānei te mata.
