I-K-Type Thermocouple Wire 2*0.8mm (800℃ Fiberglass) yokushisa okuphezulu
Incazelo Yomkhiqizo
Thayipha ikhebuli ye-K Thermocouple (2*0.8mm) eno-800℃ Fiberglass Insulation & Sheath
Uhlolojikelele Lomkhiqizo
Ikhebuli ye-thermocouple yoHlobo lwe-K (2*0.8mm) evela ku-Tankii Alloy Material iyisixazululo esikhethekile esizwa izinga lokushisa eliphezulu elakhelwe izimo zezimboni ezidlulele. Ifaka amakhondaktha amabili angumgogodla we-diameter engu-0.8mm (i-Chromel yokuthi iphozithivu, i-Alumel yokuthi inegethivu)—ipheya yesiginesha yealloy yohlobo lwe-thermocouples yohlobo K—nokuvikela okukabili: amakhondaktha angawodwana afakwe i-fiberglass enesilinganiso esingu-800℃, kanye nesheath ye-fiberglass engu-800℃ iyonke. Lesi sakhiwo se-fiberglass esiphindwe kabili, esihlanganiswe nokukhiqiza okunembayo kwe-Huona, siletha ukumelana nokushisa okungenakuqhathaniswa, ukuzinza kwesignali, nokuqina, okusenza sibe ukukhetha okuphezulu kwezimo zokulinganisa izinga lokushisa eliphezulu kakhulu lapho ukwahlukanisa okujwayelekile (i-silicone, i-PVC) kwehluleka.
Ukuqokwa Okujwayelekile
- Uhlobo lwe-Thermocouple: K (Chromel-Alumel)
- Ukucaciswa Komqhubi: 2*0.8mm (ama-conductor amabili we-thermocouple alloy alloy amabili angu-0.8mm)
- I-Insulation / Sheath Standard: I-Fiberglass ihambisana ne-IEC 60751 ne-ASTM D2307; ilinganiselwe ukusetshenziswa okuqhubekayo okungu-800 ℃
- Umkhiqizi: I-Tankii Alloy Material, egunyazwe ku-ISO 9001 kanye ne-IECEx ngezicelo eziyingozi/zezinga lokushisa eliphezulu
Izinzuzo Eziyinhloko (vs. Amakhebula Ohlobo Olujwayelekile K)
Le ntambo idlula izintambo ezijwayelekile zohlobo K ezinezinga lokushisa eliphansi ezindaweni ezintathu ezibalulekile:
- Ukumelana Nokushisa Okudlulele: 800℃ izinga lokushisa eliqhubekayo lokusebenza (isikhathi esifushane kufika ku-900℃ ihora elingu-1)—adlula kude amakhebuli afakwe i-silicone-insulated (≤200℃) ne-fiberglass evamile (≤450℃)—okuvumela ukusetshenziswa ezindaweni eziseduze nelangabi.
- Ukuqina Kwezingqimba Ezimbili: Ukufakwa kwe-fiberglass yomuntu ngamunye (yokuhlukaniswa kuka-conductor) + isheath ye-fiberglass iyonke (yokuvikela ngomshini) iphinda kabili ukumelana nokuhuzuka, ukugqwala kwamakhemikhali, nokuguga okushisayo; impilo yesevisi 3x yinde kunezintambo zokufakwa kwe-single-insulation.
- Ukunemba Kwesiginali Okungaphazamiseki: Amakhondaktha angu-0.8mm e-Chromel-Alumel anciphisa ukuncishiswa kwesignali, agcine okukhiphayo okujwayelekile kohlobo K lwe-thermoelectric (41.277mV ku-1000℃ vs. 0℃ ukusebenza) ngisho naku-800℃, ngokudonswa okungu-<0.1% ngemva kwamahora angu-50 at high-heat.
- Ukuphepha Okuthuthukisiwe: Imvelo evimbela ilangabi (isilinganiso se-UL 94 V-0), ayinabo ubuthi, futhi intuthu encane—iphephile ukusetshenziswa ezindaweni ezivalekile zezimboni (isb., iziko, amabhayela) lapho ingozi yomlilo iphezulu.

Izicelo Ezijwayelekile
- Izifudumezi Zezinga Lokushisa Eziphezulu: Ukuqapha okuqhubekayo kwezinga lokushisa ezithandweni ze-ceramic sintering, iziko lensimbi zokwelapha ukushisa (carburizing, annealing) ezisebenza ku-700-800℃.
- Ukuncibilikiswa Kwensimbi: Ukulinganisa amazinga okushisa ensimbi encibilikisiwe ezindaweni ezisekelwe kuzo, ikakhulukazi ukukhiqizwa kwensimbi ewuketshezi nensimbi (eduze nezindawo zokudonsa).
- Ukushiswa Kwemfucuza: Ukuqapha igesi ewuketshezi kanye namazinga okushisa egumbi lokusha ezindaweni zokushisela imfucuza eqinile kamasipala.
- Ukuhlolwa kwe-Aerospace: Iphrofayela eshisayo yezingxenye zenjini ye-jet namabhentshi okuhlola i-rocket nozzle ngesikhathi sokuhlolwa kokushisa okuphezulu.
- Ukukhiqiza Ingilazi: Ukulawula amazinga okushisa ku-float glass annealing lehrs nasezithandweni zokuncibilika ze-fiberglass.
I-Tankii Alloy Material ingaphansi kweqoqo ngalinye lale khebula Yohlobo K ekuhlolweni kwekhwalithi eqinile: ukuhlolwa komjikelezo oshisayo (imijikelezo engu-100 -60℃ ukuya ku-800℃), amasheke wokuhlukaniswa kwe-insulation, nokuqinisekisa ukuzinza kwe-thermoelectric. Amasampula wamahhala (ubude obu-1m) kanye nemininingwane yedatha yezobuchwepheshe enemininingwane (okuhlanganisa i-EMF vs. amajika okushisa) ayatholakala uma ecelwa. Ithimba lethu lobuchwepheshe lihlinzeka ngeziqondiso eziklanyelwe—njengokufaniswa kwesixhumi samajoyinti ezinga lokushisa eliphezulu nezinqubo ezingcono kakhulu zokufaka—ukuqinisekisa ukusebenza kahle ezindaweni ezibucayi.
