Whakataki Taupānga Taipitopito
I roto i tete rāngai whakamahana ahumahi, e mōhiotia whānuitia ana te waea Nicr7030 hei rauemi pai mō ngā huānga whakamahana taiao kino. He rerekē ki ngā rauemi whakamahana noa, ko tōna āhuatanga ahurei ārai-"pira matomato" (ātete ki te waikura intergranular) ka whakarite i te mahi pono i roto i te whakaiti i ngā hau me ngā taiao mamaoa pāmahana teitei, he mea nui mō ngā oumu ahumahi e whakamahia ana i roto i te whakamahana me te sintering whakarewa. Mō te hanga karāhe, ko te ātete pumau o te waea ka whakarite i te whakamahana ōrite o ngā oumu whakamahana me ngā taputapu kukume muka, ka ārai i ngā hapa hua i puta mai i ngā huringa pāmahana. Hei tāpiri, ko tana takai porowhita (e wātea ana i roto i ngā roera 100m-1000m) ka tautoko i te whāngai aunoa tonu, ka whakapai ake i te pai o te whakaputa mō te hanga koiri whakamahana. Ki te whakatauritea ki te waea koranu Nicr8020, ka tukuna e Nicr7030 he ngāwari ake me te whai huatanga utu, ka pai ake mō ngā tono ahumahi nui e hiahia ana ki te piko me te hanga uaua.
Mōngā taputapu whare, Mā te tere o te whakamahana o te waea Nicr7030 (tae atu ki te pāmahana kua whakaritea i roto i te 3-5 hēkona) me te tohatoha wera ōrite ka whakarei ake i te wheako kaiwhakamahi puta noa i ngā hua maha. I roto i ngā taputapu kīhini pēnei i ngā oumu me ngā ngaruiti, mā te ātete pāmahana teitei o te waea ka mau tonu te mahi mō te wā roa me te kore e heke te mahi. Mō ngā hua tiaki whaiaro pēnei i ngā paraikete hiko me ngā papa whakamahana, ka tutuki i ngā paerewa haumaru o te ao (hei tauira, IEC 60335) me te iti o te paitini me te hototahi pai ki te whakamarumaru. Ko tōna roa o te mahi (tae atu ki te 8000 hāora o te whakamahinga tonu) ka whakaiti i ngā utu tiaki me te whakakapinga mō ngā kaihanga taputapu, ā, ko ōna āhuatanga penapena-pūngao e rite ana ki ngā au o te tiaki taiao o te ao.
Teumanga motukaHe nui ngā painga o te waea Nicr7030 ki te pupuri i te pumau o te miihini i raro i ngā piki me ngā heke o te pāmahana. I roto i ngā waka hiko me ngā motuka tuku iho, ka whakamahia i roto i ngā pūnaha whakamahana nohoanga me te urungi, e whakarato ana i te mahana pumau ahakoa i roto i ngā rohe pāmahana iti -40°C. Mā te ātete waikura o te waea ka taea e ia te tu atu i te taiao makuku me te nui o ngā matū o roto o ngā motuka, ka karo i te pakaru wawe i puta mai i te makuku, i te turuturu rānei o te wai matao. Hei tāpiri, ko tōna diameter angiangi (tae atu ki te 0.1mm) ka taea te hoahoa kiato, ka uru pai ki roto i ngā roto motuka hou me te kore e noho wāhi atu.
In ngā tono hiko me te hiko, he mea nui te ātete tino pumau o te waea Nicr7030 (me te tauwehenga pāmahana o te ātete he iti iho i te 0.0004/°C) mō ngā wāhanga hiko tino tika. He whānuitia te whakamahinga i roto i ngā ātete aukume me ngā ara iahiko papa taputapu, kia tika ai te tuku tohu me te ine. Nā tōna ngāwari pai ka taea te kume ki roto i ngā waea tino pai (0.01mm) mō ngā pūoko hiko iti me ngā koiri takirere solenoid i roto i ngā raina whakaputa aunoa. Ki te whakatauritea ki te waea parahi, he teitei ake te ātete a Nicr7030, e taea ai te iti ake o ngā rahi wāhanga me te pupuri tonu i te uara ātete kotahi, he mea nui mō te ia o te whakaitiiti o ngā taputapu hiko.
In rangahau pūtaiao me te hanga matatau, Waea Nicr7030Ko te roa o te huringa wera me te āheinga ki te whakarite i ngā tukanga he taputapu tino nui. Ka tautoko i ngā whakamātautau rauemi pāmahana teitei (hei tauira, ngā whakamātautau ātete ki te waikura whakarewa) mā te tu atu i te neke atu i te 1000 huringa wera me te kore e rerekē te āhua, te ngaronga rānei o te mahi. I roto i te rangahau rererangi, ka whakamahia i roto i ngā taputapu whakaata wera hei tārua i ngā taiao pāmahana tino nui e pā ana ki ngā wāhanga rererangi. Mō te tā 3D me te hanga haurua-ira, ko te hototahi o te waea ki ngā taiao korehau me te hau kore e mahi ka whakarite kia pono te mahi i roto i ngā tukanga whakaputa motuhake. Ka tukuna hoki e mātou ngā whakatakotoranga ritenga (hei tauira, ngā koranu motuhake, ngā diameter kore-paerewa) hei whakatutuki i ngā hiahia ahurei o ngā kaupapa rangahau pūtaiao.
I te nuinga o te wā, nā te maha o ngā mahi, te pono, me te mahi pai o te waea nichrome Nicr7030, he mea pono tēnei hei whiringa pono puta noa i ngā ahumahi. Ahakoa i roto i ngā taiao ahumahi uaua, i ngā hua kaihoko o ia rā, i ngā mara rangahau hou rānei, ka tukuna tonutia e ia he mahi pumau me te whai hua. Ka whakaratohia e tā mātou kamupene he tautoko hangarau whānui, tae atu ki te kōrerorero mō te whiriwhiri rauemi, te whakamātautau tauira, me te tukatuka ritenga, hei āwhina i ngā kiritaki ki te whakanui ake i te uara o te waea Nicr7030 i roto i ā rātou tono motuhake.
