Chitoliro cholimba cha silicon carbide ceramic cholimba
Mapaipi osatha ntchito a silicon carbide ndi mapaipi opangidwa makamaka ndi silicon carbide ndipo amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana. Mpikisano wake waukulu ndi motere:
(1) Kusintha kwa Moyo
Ponyamula zinthu zonyamulira monga matope ndi phulusa la malasha, nthawi ya moyo wa zitsulo ndi yoposa nthawi 10, zomwe zimachepetsa kutayika kwa nthawi zambiri m'malo mwake komanso nthawi yopuma.
(2) Mikhalidwe yogwira ntchito kwambiri ndi yapadziko lonse lapansi
Kugwira ntchito kokhazikika kuyambira -50 ℃ mpaka 1600 ℃, ndi kukana kutentha kuti zisasweke, koyenera pazinthu zotentha kwambiri monga zitsulo ndi makampani opanga mankhwala.
(3) Kugwiritsa ntchito zinthu zingapo
Kuthetsa mavuto anayi akuluakulu okhudzana ndi kuwonongeka, dzimbiri, kutentha kwambiri, ndi kupewa kuphulika nthawi imodzi.
(4) Yopepuka komanso yopulumutsa mphamvu
Kapangidwe kopepuka kamachepetsa ndalama zoyendera ndi kukhazikitsa, ndipo kusinthasintha kochepa kumachepetsa kugwiritsa ntchito mphamvu pompa.
Ubwino wopondereza wa mapaipi a silicon carbide poyerekeza ndi zipangizo zachikhalidwe:
| Kukula kwa magwiridwe antchito | Chitoliro cha silicon carbide | Mapaipi achitsulo/pulasitiki |
| Kukana kuvala | Kulimba 2800HV (kuwirikiza kasanu kuposa chitsulo), nthawi yogwira ntchito ndi nthawi 10 kuposa nthawi ya mapaipi osakhala achitsulo | Chitsulo chimatha kusweka mosavuta, pomwe pulasitiki imakhala ndi kuuma kochepa (PE<1 HV) |
| Kutentha kwambiri kukana | Yolimba kutentha kwa 1600 ℃ komanso kutentha kwambiri (koyenera ya kutentha kwa 4 × 10 ⁻⁶/℃) | Chitsulo chosapanga dzimbiri chimatha kusungunuka kutentha kwambiri, pomwe mapulasitiki amatha kukana kutentha kosakwana 80 ℃ |
| Kukana dzimbiri | Yolimba ku asidi amphamvu (sulfuric acid yokhazikika), maziko olimba, ndi dzimbiri lachitsulo chosungunuka | Chitsulo chosapanga dzimbiri chimakumana ndi dzimbiri chikakumana ndi ma chloride ions, pomwe pulasitiki imakhala ndi mphamvu zochepa zotsutsana ndi mankhwala. |
| Wopepuka | Kuchuluka kwa 3.0~3.14 g/cm³ (60% yopepuka kuposa chitsulo) | Mapaipi achitsulo ndi olemera kwambiri ndipo amawononga ndalama zambiri powayika |
| Kukula kwa Ntchito | Ukhondo wotsutsana ndi static (conductivity yofooka), semiconductor grade ukhondo | Zitsulo zimafunikira chithandizo china chowonjezera kuti zisaphulike, pomwe mapulasitiki amatha kuipitsidwa mosavuta |
Mwachidule, palibe njira ina yothetsera mapaipi a silicon carbide ponyamula zinthu zowononga kwambiri komanso zosatha monga asidi ndi phulusa la mpweya wotentha kwambiri.
Ngati muli ndi mafunso aliwonse, chonde musazengereze kulankhulana nafe nthawi iliyonse.
Shandong Zhongpeng Special Ceramics Co., Ltd ndi imodzi mwa njira zazikulu kwambiri zothetsera zinthu zatsopano za silicon carbide ceramic ku China. SiC technical ceramic: Kuuma kwa Moh ndi 9 (Kuuma kwa New Moh ndi 13), komwe kumalimbana bwino ndi kukokoloka ndi dzimbiri, kukana bwino kwambiri - kukana komanso kukana okosijeni. Moyo wa ntchito wa SiC ndi wautali nthawi 4 mpaka 5 kuposa 92% alumina. MOR ya RBSiC ndi nthawi 5 mpaka 7 kuposa ya SNBSC, ingagwiritsidwe ntchito pazinthu zovuta kwambiri. Njira yowerengera mawu ndi yachangu, kutumiza kumakhala monga momwe kunalonjezera ndipo khalidwe lake ndi lapamwamba kwambiri. Nthawi zonse timapitilizabe kutsutsa zolinga zathu ndikubwezera mitima yathu kwa anthu.
