I roto i te mara o te hanga me te tirotiro tika, ko te mahi whakarerekētanga wera o ngā rauemi he mea nui e whakatau ana i te tika me te pono o ngā taputapu. Ko te karāneti me te rino maka, he rauemi ahumahi e rua e whakamahia whānuitia ana, kua aro nuihia mō ō rāua rerekētanga mahi i roto i ngā taiao pāmahana teitei. Hei whakaatu ā-kanohi i ngā āhuatanga whakarerekētanga wera o ngā mea e rua, i whakamahia e mātou he kaiwhakaahua wera ngaio hei whakahaere i ngā whakamātautau mahi 8-hāora tonu i runga i ngā papa karāneti me te rino maka o te whakatakotoranga kotahi, e whakaatu ana i ngā rerekētanga tūturu mā roto i ngā raraunga me ngā whakaahua.
Hoahoa whakamātautau: Whakatauira i ngā āhuatanga mahi uaua, me te hopu tika i ngā rerekētanga
Mō tēnei whakamātautau, i tīpakohia ngā papa karāhe me te rino maka, he 1000mm×600mm×100mm ngā rahi. I roto i tētahi taiao awheawhe ahumahi whakaata (pāmahana 25±1℃, haumākū 50%±5%), mā te tohatoha ōrite i ngā pūtake wera ki runga i te mata o te papa (e whakaata ana i te whakaputanga wera i te wā e whakahaerehia ana ngā taputapu), ka mahi tonu te papa i te mana o te 100W mō ngā hāora e 8. I whakamahia te whakaahua wera FLIR T1040 (me te taumira pāmahana o te 0.02℃) me te pūoko nekehanga taiaho tino tika (me te tika o te ±0.1μm) hei aroturuki i te tohatoha pāmahana me te whakarerekētanga o te mata o te papa i te wā tūturu, ā, i tuhia ngā raraunga i ia 30 meneti.
Ngā hua ine: Whakaarohia te rerekētanga o te pāmahana me te ine i te āputa whakarerekētanga
E whakaatu ana ngā raraunga mai i te whakaahua wera, i muri i te mahi a te papa rino maka mō te haora kotahi, kua eke te pāmahana mata mōrahi ki te 42℃, he 17℃ teitei ake i te pāmahana tīmatanga. E waru hāora i muri mai, ka piki te pāmahana ki te 58℃, ā, ka puta he tohatoha pāmahana motuhake, me te rerekētanga pāmahana o te 8℃ i waenga i te taha me te pokapū. He ngawari ake te tukanga whakamahana o te papa granite. Ka piki noa te pāmahana ki te 28℃ i muri i te haora 1, ā, ka pumau ki te 32℃ i muri i te 8 hāora. Ka whakahaerehia te rerekētanga pāmahana mata i roto i te 2℃.
E ai ki ngā raraunga whakarerekētanga, i roto i ngā hāora e 8, ko te whakarerekētanga poutū i waenganui o te papa rino maka i eke ki te 0.18mm, ā, ko te whakarerekētanga piko i te taha he 0.07mm. He rerekē, ko te whakarerekētanga mōrahi o te papa karāhe he 0.02mm anake, he iti iho i te 1/9 o te mea rino maka. Ko te pihi wā-tūturu o te pūoko nekehanga taiaho e whakaū ana i tēnei hua: Ka tino rerekē te pihi whakarerekētanga o te papa rino maka, ko te pihi o te papa karāhe he tata pumau, e whakaatu ana i te pumau wera tino kaha.
Tātaritanga mātāpono: Mā ngā āhuatanga rauemi e whakatau ngā rerekētanga o te whakarerekētanga wera
Ko te pūtake o te rerekētanga wera nui o te rino maka kei roto i tōna tauwehenga whānui wera teitei (tata ki te 10-12 ×10⁻⁶/℃), me te kore taurite o te tohatoha o te karāpeti ki roto, ka hua ake he tere kawe wera koretake me te hanganga o te kukū ahotea wera ā-rohe. I taua wā, he iti te kaha wera motuhake o te rino maka, ā, ka tere ake te piki o tōna pāmahana ina mimitihia te nui o te wera. He rerekē, ko te tauwehenga whānui wera o te karāhe he (4-8) ×10⁻⁶/℃ anake. He matotoru, he ōrite te hanganga tioata, he iti, he ōrite hoki te pai o te kawe wera. Me tōna āhuatanga kaha wera motuhake teitei, ka taea tonu e ia te pupuri i te pumau o te taha i roto i ngā taiao pāmahana teitei.
Te whakamāramatanga o te tono: Ko te kōwhiringa te mea e whakatau ana i te tika, ko te pumau te mea e hanga uara ai
I roto i ngā taputapu pēnei i ngā taputapu mīhini tino tika me ngā mīhini ine taunga-toru, ka taea e te whakarerekētanga wera o ngā turanga rino maka te arahi ki ngā hapa tukatuka, ki ngā hapa tirotiro rānei, ka pā ki te hua o ngā hua whai tohu. Ka taea e te turanga karāhe, me tōna pumau wera tino pai, te whakarite kia mau tonu te tika o te taputapu i te wā roa o te mahi. Whai muri i te whakakapinga o te papa rino maka e tētahi umanga hanga wāhanga motuka ki tētahi papa karāhe, ka heke te tere hapa ā-ahu o ngā wāhanga tino tika mai i te 3.2% ki te 0.8%, ā, ka piki ake te pai o te whakaputa mā te 15%.
Mā te whakaaturanga māmā me te ine tika o te whakaahua wera, ka kitea tonutia te rerekētanga o te whakarerekētanga wera i waenga i te karāhe me te rino maka. I roto i te ahumahi hou e whai ana i te tino tika, he mahi whakaaro nui te whiriwhiri i ngā rauemi karāhe he kaha ake te pumau o te wera hei whakapai ake i te mahi a ngā taputapu me te whakarite i te kounga o te hua.
