Chitoliro cha Chitetezo cha Silicon Carbide
Timapereka magwiridwe antchito apamwambaMachubu Oteteza a Silicon Carbide (SiC)Machubu athu a SiC amagwiritsidwa ntchito kwambiri m'mafakitale ovuta kwambiri, kuphatikizapo kutentha kwambiri, dzimbiri la mankhwala, kuwonongeka kwa makina komanso kutentha kwambiri. Amagwiritsidwa ntchito kwambiri mu metallurgy, kutentha, kuwotcha kwa ceramic, uinjiniya wa mankhwala ndi mafakitale a ng'anjo yotentha kwambiri, machubu athu a SiC amagwira ntchito ngati zoteteza zolemera kwambiri za ma thermocouples, ma nozzles oyaka moto, zida zosamutsira kutentha ndi zingwe za ng'anjo, zomwe zimawonjezera nthawi yogwirira ntchito ya zida ndikuchepetsa ndalama zosamalira nthawi zonse.
Timapereka magiredi atatu apamwamba kwambiri kuti agwirizane ndi zosowa zosiyanasiyana za pulogalamu:Reaction-Bonded SiC (RBSiC), Recrystallized SiC (RSiC) ndi Silicon Nitride-Bonded SiC (NBSiC).Gulu lililonse lili ndi ubwino wapadera wogwirira ntchito, ndipo timapereka ntchito zonse zopangira zomwe mukufuna kuti zikwaniritse kukula kwanu, kapangidwe kake, ndi momwe ntchito yanu ikugwiritsidwira ntchito.
1. Utumiki Wopanga Makonda | OEM & ODM Ikupezeka
Timamvetsetsa bwino kuti makasitomala amakampani ali ndi zosowa zapadera pa kukula, kapangidwe, kuyika ndi magwiridwe antchito. Timapereka mayankho athunthu a machubu oteteza a SiC, kuphatikiza kapangidwe ka zinthu, kupanga zitsanzo, kupanga zinthu zambiri komanso kuwunika bwino kwambiri. Gulu lathu laukadaulo lidzapereka lingaliro loyenera kwambiri la SiC kutengera kutentha kwanu kogwirira ntchito, mtundu wapakati, kuthamanga ndi malo oyika kuti muwonetsetse kuti ntchito yanu ikuyenda bwino komanso kuti mtengo wake ndi wokwera.
2. Kusintha kwa Makonda
(1) Kusintha kwa Miyeso:Chipinda chakunja chimakhala kuyambira Φ12mm mpaka Φ300mm, kutalika kwa chinthu chimodzi mpaka 3000mm, makulidwe a khoma amatha kusinthidwa kuyambira 3mm mpaka 30mm, ndi kulekerera kokhwima (± 0.5mm mpaka ± 1.0mm) kutengera zomwe zafotokozedwa ndi zomwe zachitika komanso zofunikira pa njira yogwirira ntchito kuti zitsimikizire kuti zikugwirizana bwino ndi zida za makasitomala.
(2) Kapangidwe ndi Kutha Kusintha:Thandizani malekezero otsekedwa, malekezero otseguka, malekezero opindika (ma flanges okhazikika ndi osakhala a muyezo), zolumikizira zamkati ndi zakunja, mipata yotsekera mphete, mabowo oyika, ndi mapangidwe ena a kapangidwe kake. Timaperekanso zinthu zopangidwa mwapadera, kuphatikiza machubu opindika a 45°/90°, machubu ochepetsera, ma tees, ndi nyumba zokhala ndi zingwe kuti zigwiritsidwe ntchito ndi kuyika.
(3) Kusintha Magwiridwe Antchito:Sinthani kupendekeka kwa zinthu, kutentha kwa mpweya, mphamvu yokakamiza, ndi magawo oletsa dzimbiri malinga ndi mikhalidwe yapadera yogwirira ntchito, konzani kapangidwe ka zinthu kuti kagwirizane ndi malo apadera ovuta, ndikukweza moyo wautumiki wolunjika komanso kukhazikika kwa magwiridwe antchito.
(4) Kusintha Njira:Kusinthana kosinthasintha pakati pa njira za RBSiC, RSiC, ndi NBSiC kutengera momwe makasitomala amagwiritsira ntchito; pazigawo zovuta za kapangidwe kake, timaika patsogolo njira yochepetsera kusinthasintha kwa kapangidwe kake kuti tichepetse ndalama zogwirira ntchito ndikuwonetsetsa kuti kapangidwe kake ndi koyenera.
Machubu Oteteza a Silicon Nitride-Bonded SiC (NBSiC)
Machubu a NBSiC amapangidwa ndi SiC yoyera kwambiri ndi ufa wa silicon, wopangidwa ndi extrusion kapena grouting, kenako n’kusungunuka pa 1350-1500°C mumlengalenga wa nayitrogeni. Makristalo a silicon nitride a acicular amamangirira tinthu ta SiC mwamphamvu, kupanga chophatikiza cholimba chokhala ndi kukana dzimbiri kwachitsulo chosungunuka komanso magwiridwe antchito osamamatira, oyenera kusungunula zitsulo zopanda chitsulo.
1. Magwiridwe Ofunika & Makhalidwe Abwino
(1) Kutentha kwakukulu kogwirira ntchito mpaka 1500°C, ndi magwiridwe antchito okhazikika mu chitsulo chosungunuka ndi malo otentha kwambiri owononga
(2) Kukana bwino kwambiri ku chitsulo chosungunuka cha aluminiyamu, zinki, mkuwa, ndi zina zosakhala ndi chitsulo, popanda kumamatira ku zitsulo zosungunuka komanso kuipitsidwa kwa madzi achitsulo.
(3) Kutentha kwambiri, komwe kumathandiza kuzindikira kutentha mwachangu komanso kusamutsa kutentha bwino kuti kuwunikira kutentha molondola
(4) Mphamvu yabwino yamakina komanso kukana kutentha, yoyenera kugwiritsidwa ntchito kwa nthawi yayitali mu smelting ndi casting yachitsulo
(5) Kuchepetsa ma porosity ndi kapangidwe kokhuthala, zomwe zimathandiza kuti zitsulo zosungunuka, slag, ndi mpweya wowononga zitetezeke mkati mwa zinthu.
2. Mapulogalamu Ovomerezeka
Machubu oteteza a NBSiC amapangidwira makamaka mafakitale opangira zitsulo, makamaka machubu oyezera kutentha kwachitsulo chosungunuka, machubu okweza, manja oteteza thermocouple ya ng'anjo ya aluminiyamu/mkuwa/zinc, zida zotetezera dziwe losungunuka, ndi zida zoponyera mosalekeza. Ndi njira yabwino kwambiri yothetsera dzimbiri lachitsulo chosungunuka komanso zofunikira pakugwira ntchito kosamamatira.
Machubu Oteteza a Reaction-Bonded SiC (RBSiC)
Machubu a RBSiC amapangidwa pogwiritsa ntchito ukadaulo wapamwamba wolowerera ndi kupopera kwa reaction, pogwiritsa ntchito ufa wa SiC woyera kwambiri ndi zinthu zopangira kaboni. Silikoni yosungunuka imalowa m'thupi lobiriwira ndikuchitapo kanthu mkati mwake kuti ipange kapangidwe kolimba kogwirizana, ndi 8-15% ya silicon yopanda kanthu. Njirayi imalola kupanga mawonekedwe ofanana ndi netiweki okhala ndi kuchepera kwa 1%, kupereka ndalama zambiri komanso koyenera kupanga mafakitale ambiri.
1. Magwiridwe Ofunika & Makhalidwe Abwino
(1) Kutentha kwakukulu kogwirira ntchito mpaka 1400°C, ndi magwiridwe antchito okhazikika kwa nthawi yayitali pa kutentha kwakukulu kosalekeza
(2) Kuchuluka kwambiri, mphamvu yabwino kwambiri yamakina, komanso kukana bwino kugwedezeka ndi makina komanso kuvala pang'ono
(3) Kugwiritsa ntchito bwino ndalama poyerekeza ndi mitundu ina ya SiC, yoyenera kugwiritsidwa ntchito m'mafakitale akuluakulu.
(4) Kupangika bwino kwambiri, komwe kumathandiza kupanga zinthu zooneka ngati zovuta popanda kukonza kwambiri
(5) Kukana bwino dzimbiri la mankhwala, kuphatikizapo mpweya wamafuta ndi wamchere m'mafakitale
2. Mapulogalamu Ovomerezeka
Machubu oteteza RBSiC amagwiritsidwa ntchito kwambiri pa machubu a radiation a ng'anjo yachitsulo, manja oteteza a thermocouple wamba, ma nozzles ochotsa sulfurization, zosinthira kutentha, ndi zida zonse za ng'anjo yotentha kwambiri. Ndiwo chisankho chabwino kwambiri pakugwiritsa ntchito komwe kumafuna magwiridwe antchito oyenera komanso kuwongolera mtengo, popanda kufunikira kwa kukana kutentha kwambiri kuposa 1400°C.
Machubu Oteteza a SiC (RSiC) Obwezeretsedwanso
Machubu a RSiC amatenthedwa pa kutentha kwambiri (2100-2450°C) popanda gawo lina lililonse lomangirira, lopangidwa ndi kutenthedwa mwachindunji ndi kusungunuka kwa tinthu ta α-SiC toyera kwambiri. Kapangidwe kake koyera ka kristalo kamatsimikizira kuti palibe kuipitsidwa konse, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pa malo ogwirira ntchito otentha kwambiri komanso oyera kwambiri.
1. Magwiridwe Ofunika & Makhalidwe Abwino
(1) Kukana kutentha kwambiri, ndi kutentha kopitilira mpaka 1800°C, koyenera kugwira ntchito pa kutentha kwambiri
(2) Gawo la kristalo la SiC loyera 100%, lopanda kuipitsidwa, labwino kwambiri pochiza kutentha koyera kwambiri komanso uvuni wolamulidwa ndi mlengalenga
(3) Kukana kutentha kwambiri, komwe kumatha kupirira kusintha kwa kutentha mwachangu popanda kusweka kapena kuwonongeka
(4) Kutentha kwambiri komanso kukhazikika bwino pa kutentha kwambiri, kusunga umphumphu wa kapangidwe kake pansi pa kutentha kwambiri kwa nthawi yayitali
(5) Kukana kwambiri kukokoloka kwa mpweya ndi kuwonongeka kwa mpweya, koyenera malo ovuta a uvuni okhala ndi madzi ambiri komanso kukhudzidwa ndi tinthu tating'onoting'ono.
2. Mapulogalamu Ovomerezeka
Machubu oteteza a RSiC amagwiritsidwa ntchito makamaka m'mauvuni otentha kwambiri, m'zitofu zotenthetsera mpweya, m'mafakitale otenthetsera kutentha, m'ma nozzles otenthetsera kutentha kwambiri, zida zoyatsira zadothi zoyera kwambiri, ndi zida zapadera zoyatsira kutentha kwambiri. Sizingasinthidwe pazochitika zomwe zimafuna kukana kutentha kwambiri, kuyera kwambiri, komanso kukhazikika kwa kutentha kwambiri.
