- Ngā Whakatakotoranga MatuaAwhe pāmahana 0-1300℃ (whakamahinga poto ki te 1400℃ mō te ≤30min); roa katoa 250mm (roa pito ine 50mm, roa waea mata 200mm); diameter waho o te ngongo tiaki uku 7-8mm (matotoru pakitara 1.2-1.5mm); diameter waea arataki 0.2mm (manawanui ±0.01mm)
- Ngā Paerewa Whaimana: IEC 60584-1 (akomanga tika o te thermocouple), GB/T 1672-1997 (ngā thermocouple platinum-rhodium), ASTM E230-19 (paerewa mō ngā thermocouple whakarewa rangatira)
- KaihangaRauemi Koranu Tankii, kua whakamanahia ki te ISO 9001 me te ISO 14001, me ngā āheinga whakarewa koranu whakarewa rangatira me te whakatikatika pūoko i roto i te whare.
Ngā Painga Matua Matua (I whakaritea mō te 0-1300℃ me ngā Whakatakotoranga Hanganga)
1. Te Ine i te Pāmahana Teitei me te Pūmautanga
E whakamahi ana i te waea arataki Pt10Rh/Pt tino parakore 99.99% (te whānui 0.2mm) me te hanganga koranu ōrite—ka eke te tika o te ine ki te Akomanga 1 (hapa ≤±1.5℃ i te 0-600℃, ≤±0.25% t i te 600-1300℃, t=te pāmahana i inehia). I muri i te 1000 hāora o te mahi tonu i te 1200℃, ko te nekehanga pūmanawa thermoelectric he <3μV (he rite ki te hapa pāmahana <0.4℃)—he pai ake i ngā takirua thermotype-K (neke >10μV i te 800℃) ā, he pai mō te aroturuki pāmahana teitei mō te wā roa.
2. Te Pūmautanga Hanganga Arotau
- Ngongo Tiaki Uku: uku konumohe-teitei te whānui o waho 7-8mm (he ≥95% te ihirangi Al₂O₃) me te ātete pāmahana teitei tae atu ki te 1600℃, te kaha pēhi ≥150MPa—he whai hua ki te wehe i te konganuku rewa, te puehu oumu, me ngā hau waikura me te whakarite i te pai o te whakawhiti wera (te kawe wera ≥20 W/(m·K) i te 800℃).
- Hoahoa Kaiārahi me te HonongaKo te diameter o te ara iahiko he 0.2mm te whānui, e whakataurite ana i te ngāwari me te kaha pāmahana teitei (kaha kume ≥350MPa i te 25℃, ≥150MPa i te 1300℃); ka whakamahia te pito ine hei whakarewa ira (diameter ira whakarewa 0.3-0.4mm) hei whakarite i te putanga pūmanawa hiko wera pumau me te kore he ātete pa.
- Te Whakataurite i te Roa KatoaKo te roa katoa o te 250mm (te pito ine 50mm + te waea mata 200mm) kua arotauhia mō te tāutanga pakitara taha oumu ahumahi—ka karo i te piko nui o te waea mata, me te whakarite kia tae te pito ine ki te rohe pāmahana matua.
3. Te Pono i Whakaritea ki te Taupānga
He pai te ātete o te pūoko ki te waikura (ka hanga he kiriata tiaki PtO₂ matotoru i te pāmahana teitei) me te ātete ki ngā ru wera (ka taea te tu atu i te huringa pāmahana 500℃/min me te kore e pakaru te ngongo uku). Ka whakamahia e te waea mata he whakamarumaru Teflon pāmahana-tiketike (pāmahana mahi -60℃ ki te 260℃) hei ārai i ngā ara iahiko poto i roto i ngā awheawhe pāmahana-tiketike, ā, kua rite te pūrua ki te hononga M12 paerewa hei hono tere ki ngā tuku pāmahana.
