I ngā taiao ahumahi e werohia ana ngā rauemi e te pāmahana teitei, te pēhanga, me te kakahu, he mea nui ngā otinga pono.Ngā pereki Sillimanitee tū ana hei "hōiho mahi ahumahi," me ngā āhuatanga tino pai e whakanui ana i te whai huatanga, e whakaiti ana i ngā utu, e whakapai ake ana hoki i te kounga o te hua puta noa i te mahi whakarewa, te mahi uku, me te hanga karāhe. Koinei te take he whiringa matua rātou puta noa i te ao.
1. Ngā Āhuatanga Matua: He aha te mea e tino hiahiatia ai ngā pereki Sillimanite
I ahu mai i te kohuke aluminosilicate sillimanite, e toru ngā painga nui o ēnei pereki:
Te Ātete Tino-Teitei:Neke atu i te 1800°C te pāmahana rewa, ā, ka ātete ki te wera nui (he mea nui mō te whakarewa whakarewa me te whakarewa karāhe, ina neke atu i te 1500°C te pāmahana) me te kore e piko, e memeha rānei.
Te Whakawhanuitanga Wera Iti:Mā te tere i raro i te 1% i te 1000°C ka ārai i te pakaru mai i te ru wera, ka mau tonu te pakari i roto i ngā taiao whakamahana-whakamatao hurihuri pērā i ngā oumu pupuhi.
Ātete Pai Rawa:He mārō, he matotoru hoki, ā, e ātete ana ki te pakū mai i ngā konganuku rewa/para me te horo matū mai i ngā waikawa/kawakore—he mea nui mō te tukatuka matū me te mahi whakarewa.
Mā ēnei āhuatanga ka hurihia ngā pereki sillimanite mai i te "mea pai ki te whai" ki te "mea me whai" mō te whakapai ake i te mahi.
2. Te Whakarewa: Te Whakapai Ake i te Hanganga Rino me te Whakarewa
He nui te whakawhirinaki o te umanga whakarewa ki ngā pereki sillimanite mō ngā taputapu e pehia ana e te wera:
Ngā Ārai o te Ouma Pahū:I te taha o te "rohe wera" (1500–1600°C) o ngā oumu whakaputa rino, he pai ake tā rātou mahi i ngā pereki ahi tuku iho. I kite tētahi wheketere rino i te 30% te roa o te ora o te oumu, ā, i te 25% te iti iho o ngā utu tiaki i muri i te whakawhiti.
Ngā Raina Tundish me te Ladle:Mā te whakaiti i te poke o te konganuku, me te whakaroa i te roa o te ora o te arai ki te 40% (e ai ki tētahi kaihanga rino Pākehā), ka whakarite kia maeneene ake te whakahaere o te rino rewa.
Ngā Ipu Whakakore Whewhe:Ko te ātete ki te para nui-whanariki ka mau tonu te ōritetanga, ā, ka āwhina i te whakatutuki i ngā paerewa parakore o te maitai.
Ki ngā tohunga whakarewa, he haumi rautaki ngā pereki sillimanite ki te whakaputa hua.
3. Uku: Te Whakarei i te Tāera, Ngā Taonga Parakore me ngā Uku Hangarau
I roto i ngā pereki uku, e rua ngā mahi matua a te pereki sillimanite:
Ngā Ārai Oihu:Mā te pupuri i te wera ōrite (tae atu ki te 1200°C) i roto i ngā oumu tahu, ka āraihia e tōna iti o te horapa te kino. I whakahekehia e te kaihanga taera Hainamana ngā pire hiko mā te 10% i muri i te whakahoutanga, me te 15–20% te iti iho o te whakamahinga hiko katoa.
Tāpiri Rauemi Mata:Ina hurihia hei paura (5–10% i roto i ngā ranunga), ka whakanui ake i te kaha ā-ringa (25% teitei ake te kaha piko) me te pumau wera (30% iti iho te kino o te ru wera) i roto i ngā uku hangarau.
4. Te Hanga Karāhe: Te Whakataurite i te Kounga me te Utu;
Ka whakatauhia e ngā pereki Sillimanite ngā wero nui o te hanga karāhe:
Ngā Kaiwhakaora Oil:Mā te whakapuru i ngā pūwhakahou e hopu ana i te wera, ka ātete rātou ki te pakaru me te urunga o te kohu karāhe. I kite tētahi kaihanga o Amerika Te Raki i te roa ake o te ora o ngā pereki e rua tau te roa, me te tapahi i ngā utu whakakapinga mā te $150,000 mō ia oumu.
Karāhe Motuhake:Me te iti iho i te 0.5% te waikura rino, ka karohia e rātou te poke o te karāhe whatu, te karāhe borosilicate rānei, kia mārama ai, kia pumau ai hoki ngā matū mō ngā mata taiwhanga, ngā mata waea atamai rānei.
5. Matū me Ētahi Atu Ahumahi: Te Whakahaere i ngā Āhuatanga Kino
Te Tukatuka Matū:Mā te whakapuru i ngā tauhohenga pāmahana teitei, ka ārai i ngā turuturu me te whakaroa i te ora o ngā taputapu—he mea nui mō te haumaru i roto i te hanga tongi, te hinu matū, te rongoā rānei.
Te tahunga para:He ātete ki te wera o te 1200°C me te mimiti o ngā para, ka whakaitihia te mahi tiaki i ngā tipu whakamahi para-ki-te-pūngao.
Kōwhiria ngā pereki Sillimanite mō te angitū roa
Ahakoa he kaihanga rino koe, he kaihanga uku, he kaihanga karāhe rānei, ka puta ngā hua pai mai i ngā pereki sillimanite. Nā te ranunga ahurei o te ātete-wera, te iti o te whānui, me te ātete, he otinga utu-pai, he maha ngā whakamahinga.
