Ngā Oumu Momo-Pere

Tirohanga Whānui:
Ko ngā oumu momo-pere e whakamahia ana mō te whakamahana kanapa me te whakamahana, nō reira he oumu rerekē-pāmahana ā-wā. Ka noho te pāmahana i waenga i te 650 me te 1100 ℃ te nuinga, ā, ka rerekē i te wā kua tohua i roto i te pūnaha whakamahana. I runga i te uta o ngā oumu momo-pere, e rua ngā momo: te oumu momo-pere tapawhā me te oumu momo-pere porowhita. Ko ngā pūtake wera o ngā oumu momo-pere he hau te nuinga, ā, muri iho ko te hiko me te hinu māmā. I te nuinga o te wā, e toru ngā wāhanga o ngā oumu momo-pere: he taupoki o waho, he taupoki o roto, me te oumu. Ko te taputapu tahu ka whakatakotoria ki runga i te taupoki o waho kua whakamahanahia ki te paparanga wera, ko ngā wahi mahi ka whakanohoia ki roto i te taupoki o roto hei whakamahana me te whakamatao.

He pai te ātete hau o ngā oumu momo-pere, he iti te ngaronga wera, ā, he pai te whakamahinga wera. Heoi anō, kāore e hiahiatia he tatau oumu, he tikanga hiki me ētahi atu tikanga tuku miihini, nō reira ka penapena utu, ā, he whānuitia te whakamahinga i roto i ngā oumu whakamahana o ngā mea mahi.
Ko ngā whakaritenga tino nui e rua mō ngā rauemi arai oumu ko te mama me te whai huatanga o te pūngao o ngā taupoki whakamahana.

Ngā raruraru noa o te refracto māmā tuku ihopereki Ry, pereki whakarewa māmā rāneingā hanganga ko:

1. Ko ngā rauemi ātete-ātete he nui te taumaha motuhake (ko te tikanga he 600KG/m3, neke atu rānei, ngā pereki ātete-ātete māmā noa; ko te 1000 KG/m3, neke atu rānei, ngā pereki whakarewa māmā) me nui te kawenga ki te hanganga maitai o te taupoki oumu, nō reira ka piki ake te whakapaunga o te hanganga maitai me te haumi ki te hanganga oumu.

2. Ka pā te taupoki o waho matotoru ki te kaha hiki me te wāhi papa o ngā awheawhe whakaputa.

3. Ka whakahaerehia te oumu momo-pere i ngā pāmahana rerekē, ā, he nui te kaha wera motuhake o ngā pereki ātete-wera māmā, ngā pereki whakarewa māmā rānei, he nui hoki te kawe wera, ā, he nui hoki te whakapaunga pūngao.

Heoi, he iti te kawe wera o ngā hua muka ātete CCEWOOL, he iti te rokiroki wera, he iti hoki te mātotoru rōrahi, koinei ngā take matua mō te whānui o ā rātou whakamahinga i roto i ngā uhi whakamahana. Ko ngā āhuatanga e whai ake nei:

1. He whānuitanga pāmahana mahi me ngā momo tono rerekē
I te whanaketanga o te hanga me te hangarau muka uku CCEWOOL, kua tutuki i ngā hua muka uku CCEWOOL te raupapatanga me te mahi. Mō te pāmahana, ka taea e ngā hua te whakatutuki i ngā whakaritenga o ngā pāmahana rerekē mai i te 600 ℃ ki te 1500 ℃. Mō te āhua, kua āta whanake haere ngā hua i ngā momo tukatuka tuarua, tukatuka hōhonu rānei mai i te miro tuku iho, ngā paraikete, ngā hua huruhuru ki ngā wae muka, ngā papa, ngā wāhanga āhua motuhake, te pepa, ngā kakahu muka me ētahi atu. Ka taea e rātou te whakatutuki katoa i ngā whakaritenga o ngā oumu ahumahi mō ngā hua muka uku i roto i ngā ahumahi rerekē.
2. Te iti o te mātotoru o te rōrahi:
Ko te matotoru o ngā hua muka uku he 96~160kg/m3 te nuinga, arā, he 1/3 o ngā pereki māmā me te 1/5 o te pereki ātete-whakarewa māmā. Mō te oumu hou, mā te whakamahi i ngā hua muka uku ka taea te whakaora i te maitai, engari ka māmā ake te uta/tango me te kawe, ka akiaki i te ahunga whakamua o te hangarau oumu ahumahi.
3. Te iti o te kaha wera me te rokiroki wera:
Ki te whakatauritea ki ngā pereki ātete me ngā pereki whakamarumaru, he iti iho te kaha o ngā hua muka uku, tata ki te 1/14-1/13 o ngā pereki ātete me te 1/7-1/6 o ngā pereki whakamarumaru. Mō te oumu momo pere e whakahaerehia ana i ia wā, ka taea te penapena i te nui o te wahie e pau ana i waho o te mahi whakaputa.
4. Hanganga māmā, wā poto
Nā te mea he tino ngāwari ngā paraikete muka uku me ngā kōwae, ka taea te matapae i te nui o te pēhanga, ā, kāore he take e waiho ai ngā hononga whakawhanui i te wā hanga. Nō reira, he māmā noa iho te hanga, ā, ka taea te whakaoti e ngā kaimahi pūkenga noa.
5. Te whakahaere me te kore he oumu
Mā te whakamahi i te arai muka-katoa, ka taea te whakamahana tere i ngā oumu ki te pāmahana tukatuka mena kāore e herea e ētahi atu wāhanga whakarewa, ka tino whakapai ake i te whakamahinga whai hua o ngā oumu ahumahi me te whakaiti i te whakapaunga wahie kāore e pā ana ki te whakaputanga.
6. He iti rawa te kawe wera
He huinga muka uku te muka uku, he whānui o te 3-5um, nō reira he iti rawa te kawe wera. Hei tauira, ina tae te paraikete muka konumohe-teitei me te mātotoru o te 128kg/m3 ki te 1000℃ i te mata wera, ko te tauwehenga whakawhiti wera he 0.22(W/MK) anake.
7. He pai te pumau matū me te ātete ki te mimiti o te hau:
Ka taea anake te memeha o te muka uku i roto i te waikawa phosphoric, te waikawa hydrofluoric, me te alkali wera, ā, he pumau ki ētahi atu momo waikura. Hei tāpiri, ka hangaia ngā kōwae muka uku mā te whakapiko tonu i ngā paraikete muka uku i tētahi ōwehenga pēhanga. I muri i te maimoatanga o te mata, ka taea e te ātete ki te memeha o te hau te eke ki te 30m/s.
