Ngā Ngongo Matotoru Kiriata Hiraka: Te Otinga Ātete-Wera Tino Pai mō ngā Whare Hanga Sima

I roto i te taiao hanga sima e wera ana, e mimiti ana, ko te mahi a ngā wāhanga taputapu wera e whakatau tika ana i te pai o te whakaputanga, te haumaru mahi, me te whakahaere utu. Hei wāhanga wera matua, he mea nui te kounga o ngā ngongo tiaki thermocouple me ngā ngongo whakawhiti wera. I tēnei rā, ka whakauruhia e mātou he hua whakarerekētanga kēmu mō ngā tipu sima puta noa i te ao:ngā ngongo moroiti tioata silicon carbide— i hangaia hei tu atu i ngā āhuatanga tino uaua, hei whakapiki ake i te hanga sima ki ngā taumata hou.

He aha te mea nui o ngā ngongo iti-kirikiri Silicon Carbide mō ngā whare hanga sima

Ko te hanga sima he tukanga uaua pērā i te whakapūkara rauemi mata, te whakapūkara clinker, me te huri sima, ā, ko ngā hononga matua pērā i te oumu hurihuri, te whakamahana mua, me te pouaka whakamatao ka mahi i ngā pāmahana neke atu i te 1200°C. He maha ngā wā ka pāngia ngā ngongo whakarewa, uku rānei tuku iho e te pakaru tere, te waikura, te pakaru rānei o te ru wera, ka hua ake he whakakapinga pinepine, he wā kore mahi i whakaritea, me te pikinga o ngā utu tiaki. Ko ngā ngongo moroiti tioata silicon carbide, me ō rātou āhuatanga rauemi ahurei, ka tino aro atu ki ēnei āhuatanga mamae.

Ngā Painga Matua o ā Mātou Ngongo Matotoru Silicon Carbide

1. Ātete Tino Pai ki te Pāmahana Teitei

E whakamanamana ana ā mātou ngongo moroiti tioata silicon carbide ki te ira rewa neke atu i te 2700°C, ā, ka taea te mahi pumau mō ngā wā roa i ngā pāmahana tae atu ki te 1600°C. Ahakoa i roto i te wera nui o te rohe tahunga o te oumu hurihuri, ka mau tonu te hanganga me te kore e rerekē te āhua, e ngatata rānei. Mā tēnei ka whakarite kia pono te ine wera me te mahi whakawhiti wera, ka whakakore i te mōrearea o te rahunga taputapu i puta mai i te kino o te pāmahana teitei.

2. Ātete Pai ki te Mau me te Waikura

He nui ngā matūriki whakakoi (pērā i te paraoa mata, te kinker, me te puehu) me ngā hau waikura (pērā i te CO₂, SO₂) ka puta mai i te hanga sima. Ko te pakeke o te rauemi silicon carbide microcrystalline he 9.2, ko tōna tuarua ko te taimana, ā, he tino ātete ki te waikura. Hei tāpiri, he koretake ki te nuinga o ngā waikawa, ngā kawakore, me ngā hau waikura, ā, ka ārai pai i te pirau o ngā ngongo me te whakaroa i te roa o te mahi mā te 3-5 ngā wā ki te whakataurite ki ngā hua tuku iho.

3. Ātete Ru Wera Pai rawa atu

He maha ngā wā ka pāngia ngā tipu sima e ngā piki me ngā heke tere o te pāmahana i te wā e tīmata ana, e whakaweto ana, e whakarerekē ana rānei i te kawenga. He iti te tauwehenga whānui wera o ngā ngongo moroiti karaihe silicon carbide, ā, he kaha te ātete ki te ru wera, ka taea te tu atu i ngā huringa pāmahana ohorere neke atu i te 800°C me te kore e pakaru. Ka whakaitihia e tēnei āhuatanga te auau o te whakakapinga ngongo nā te ru wera, ka whakapai ake i te haere tonu o te whakaputa.

4. Teitei o te Ahurea Wera me te Tika o te Ine

Mō ngā ngongo tiaki thermocouple, he mea nui te ine tika i te pāmahana hei whakapai ake i te tukanga whakapūkara. He tino pai te kawe wera o te rauemi silicon carbide microcrystalline, e whakarite ana kia rite te pāmahana i kitea e te thermocouple ki te pāmahana tuturu o te taiao whakaputa. Mā tēnei ka āwhina i ngā tipu sima ki te whakatutuki i te whakahaere tika o te tukanga sintering, te whakapai ake i te kounga clinker, me te whakaiti i te whakapaunga pūngao.
