He momo karāhe motuhake te karāhe borosilicate teitei e mōhiotia ana mō ōna āhuatanga tino pai, inā koa i roto i te horopaki o te ātete wera me te kaha miihini. E kiia ana he pai ake i te karāhe noa i roto i ngā momo whakamahinga, mai i ngā taputapu taiwhanga ki ngā taputapu tunu kai kounga teitei. Kei raro nei, ka ruku hohonu atu mātou ki ngā rerekētanga matua i waenga i te karāhe borosilicate teitei me te karāhe noa, e whakamārama ana he aha i pai ai te rauemi i roto i ētahi ahumahi.
1. Tauwehenga o te Whanuitanga Wera
Ko te tauwehenga whānui wera (CTE) he ine mō te nui o te whānui, te whakawhāiti rānei o tētahi rauemi ina rerekē te pāmahana. He mea nui tēnei āhuatanga i roto i ngā tono e pāngia ana ngā rauemi e ngā rerekētanga pāmahana tino nui.
- Karāhe Borosilicate TeiteiKo tētahi o ngā āhuatanga tino kitea o te karāhe borosilicate teitei ko tōna tauwehenga iti o te whakawhānui wera. Tata ki te hautoru o te karāhe noa, ko te tikanga he iti ake te whakawhānui me te whakawhāiti ina pāngia e ngā huringa pāmahana. Mā tēnei ka whakaitihia te tūponotanga o te pakaru, te pakaru rānei nā te ahotea wera. Nō reira, he tino ātete te karāhe borosilicate teitei ki te ru wera, he mea pai mō ngā mahi pēnei i ngā karāhe taiwhanga, ngā kohua tunu kai, me ngā ipu e pāngia ana e ngā huringa pāmahana ohorere.
- Karāhe NoaHe nui ake te tauwehenga whānui wera o te karāhe noa. Nō reira, he ngāwari ake ki te pāngia e te ahotea mai i ngā huringa pāmahana tere. Hei tauira, ina werahia, ina whakamataohia rānei te karāhe noa, ka nui te whānui, te whakaheke rānei o te rauemi, ka puta he ahotea ka arahi ki ngā pakaru, ki te pakaru rawa rānei. Koia te take kāore i te tūtohutia te karāhe noa mō ngā tono e tino hira ana te ātete ki te ru wera.
2. Ngā Wāhanga Matua
He mea nui te hanganga o te karāhe ki te whakatau i ōna āhuatanga ā-tinana me te matū. Kua hangaia te karāhe borosilicate teitei hei whakarato i te kaha me te ātete pai ki te ahotea wera me te matū.
- Karāhe Borosilicate TeiteiKo te nuinga o tēnei momo karāhe he boron trioxide (tae atu ki te 14%) me te silicon dioxide (tae atu ki te 80%). Mā te whakauru o te boron ka whakarei ake i te ātete o te karāhe ki te ru wera, nā te mea ka āwhina ngā ngota boron ki te whakaiti i te whānui o te karāhe i te wā e whakamahana ana, e whakamatao ana hoki. Hei tāpiri, nā te hanganga matū o te karāhe borosilicate ka tino ātete ki ngā momo matū, waikawa, me ngā kawakore, ka pai ai te whakamahi i roto i ngā taiwhanga me ngā ahumahi kei reira te pānga o ngā matū kino.
- Karāhe NoaKo te karāhe noa he mea hanga tuatahi mai i te konutai konupūmā silicate, me te silica (SiO2) hei wāhanga matua. Kāore he boron i roto i te hanganga o te karāhe noa, e whakawhāiti ana i tōna kaha ki te tu atu i te ahotea wera me ngā taiao matū kino. Ahakoa he pai mō ngā tono noa pēnei i ngā matapihi me ngā pounamu, kāore i a ia ngā āhuatanga matatau e hiahiatia ana mō ngā whakamahinga uaua ake.
3. Kaha Kume
Ko te kaha kume e pā ana ki te kaha o te rauemi ki te tu atu i ngā kaha kume, totoro rānei. Ka taea e ngā karāhe he kaha kume teitei ake te tu atu i te kaha nui ake i mua i te whati, i te pakaru rānei.
- Karāhe Borosilicate TeiteiHe nui ake te kaha kume o te karāhe borosilicate teitei i te karāhe noa. Ko te tikanga ka taea e ia te tu atu i ngā ahotea miihini nui ake me te kore e pakaru. Ina pakaru te karāhe borosilicate teitei, ka pakaru ki ngā wahi nui ake, rite ki te wae kotahi, kaua ki te pakaru ki ngā kongakonga koi, morearea. Nā tēnei ka haumaru ake te whakahaere i roto i ngā taiao ka tūpono te pakaru.
- Karāhe NoaHe iti ake te kaha o te karāhe noa, ā, he ngāwari ake te pakaru i raro i te taumahatanga. Ina pakaru, ka pakaru te karāhe noa ki ngā wahi iti, koi, ka puta he tūponotanga haumaru. Koinei tētahi take e karohia ai te karāhe noa i roto i ngā mahi taumahatanga nui, pānga nui rānei.
4. Ātete ki te Ru Wera
Ko te ātete ki ngā ru wera ko te kaha o tētahi rauemi ki te tu atu i ngā huringa pāmahana tere me te kore e pakaru, e ngatata rānei. He mea nui tēnei āhuatanga mō ngā rauemi e whakamahia ana i roto i te tunu kai, i ngā taiwhanga, me ētahi tukanga ahumahi.
- Karāhe Borosilicate TeiteiKo tētahi o ngā painga matua o te karāhe borosilicate teitei ko tōna ātete tino pai ki te ru wera. Ka taea e ia te tu atu i ngā huringa pāmahana tino tere me te kore e pakaru. Hei tauira, ka taea e ia te tu atu ki te tāpiri wai kohua (100°C) ki te karāhe ahakoa ka whakanohoia ki roto i te taiao hukapapa (-30°C). Nā tēnei he kōwhiringa pai mō ngā taputapu tunu kai (pēnei i ngā rihi tunu karāhe), ngā taputapu taiwhanga, me ētahi atu tono e kitea whānuitia ana ngā huringa pāmahana.
- Karāhe NoaKo te karāhe noa ia, he tino ngāwari ake ki te pāngia e te ru wera. Ina pāngia e ngā huringa ohorere o te pāmahana, tera pea ka pakaru, ka pakaru rānei nā te tere o te horapa, te whakawhāiti rānei o te rauemi. Koia te take kaua rawa e tukuna ngā ipu karāhe noa ki te wai kohua, kaua hoki e waiho tika mai i te taiao makariri ki roto i te taiao wera.
Ngā Whakamahinga o te Karāhe Borosilicate Teitei
I runga i ōna āhuatanga pai rawa atu, ka whakamahia te karāhe borosilicate teitei i roto i te whānuitanga o ngā tono e hiahia ana ki te mahi teitei, te haumaru, me te roa:
- Ngā Ipu Karāhe TaiwhangaNā tōna ātete ki te ru wera me te waikura matū, e whakamahia whānuitia ana te karāhe borosilicate teitei i roto i ngā taiwhanga mō ngā ipurau, ngā pounamu, ngā ngongo whakamātautau, me ētahi atu taputapu e hiahia ana kia tū atu i te wera me ngā matū.
- Ngā taputapu tunu kaiKei te piki haere te whakamahinga o te karāhe borosilicate teitei i roto i ngā taputapu kīhini pērā i ngā rihi tunu kai, ngā kapu ine, me ngā taputapu tunu kai, ā, ko tōna ātete ki te wera me te ru wera he painga matua.
- Ngā Taputapu WhatuNā te māramatanga whatu teitei o te karāhe borosilicate he mea pai mō ngā arotahi me ētahi atu taputapu whatu.
- Rama me ngā HikohikoE whakamahia ana te karāhe borosilicate teitei i roto i ētahi wāhanga rama me ngā wāhanga hiko, he mea nui tōna roa me tōna ātete ki te wera.
Whakamutunga
He rauemi matatau te karāhe borosilicate teitei e tino pai ana mō ngā tono e hiahia ana ki te ātete ki te wera, te ahotea miihini, me te pānga matū. Nā te iti o te horapa wera, te kaha kume teitei, me te ātete tino pai ki te ru wera, he pai ake i te karāhe noa mō ngā tono uaua i roto i ngā mara pēnei i te mahi taiwhanga, te tunu kai, me ngā tukanga ahumahi. Ahakoa he pai te karāhe noa mō ngā kaupapa whānui, mā ngā āhuatanga ahurei o te karāhe borosilicate teitei ka noho tonu hei rauemi whiriwhiri i roto i ngā tono motuhake e tino hira ana te mahi me te haumaru.
