Silicon carbide ceramic yokhala ndi chitoliro chosamva kuvala
Mapaipi osamva kuvala a Silicon carbide ndi mapaipi opangidwa makamaka ndi silicon carbide ndipo amagwiritsidwa ntchito kwambiri m'magawo angapo. Kupikisana kwake kwakukulu kuli motere:
(1) Life Revolution
Ponyamula zinthu zowononga monga slurry ndi phulusa la malasha, nthawi ya moyo ndi nthawi 10 kuposa zitsulo, kuchepetsa kusinthidwa pafupipafupi komanso kutaya nthawi.
(2) Mikhalidwe yogwira ntchito kwambiri ndi yapadziko lonse lapansi
Khola ntchito kuchokera -50 ℃ mpaka 1600 ℃, ndi kukana matenthedwe mantha kupewa akulimbana, oyenera zochitika mkulu-kutentha monga zitsulo ndi makampani mankhwala.
(3) Kugwiritsa ntchito kangapo kwa chinthu chimodzi
Panthawi imodzimodziyo thetsani mavuto anayi akuluakulu ovala, dzimbiri, kutentha kwambiri, ndi kupewa kuphulika.
(4) Zopepuka komanso zopulumutsa mphamvu
Mapangidwe opepuka amachepetsa mtengo wamayendedwe ndi kukhazikitsa, ndipo kugundana kocheperako kumachepetsa kupopera mphamvu.
Ubwino wophwanyidwa wa mapaipi a silicon carbide poyerekeza ndi zida zachikhalidwe:
| Kachitidwe kachitidwe | Silicon carbide pipeline | Mipope yachitsulo/Pulasitiki |
| Valani kukana | Kulimba 2800HV (nthawi 5 kuposa chitsulo), moyo wautali nthawi 10 kuposa mapaipi omwe si azitsulo | Chitsulo chimakonda kuvala ndi kung'ambika, pamene pulasitiki imakhala yolimba kwambiri (PE <1 HV) |
| Kutentha kwakukulu kukaniza | Kulimbana ndi kutentha kwakukulu kwa 1600 ℃ ndi kugwedezeka kwamafuta (coefficient of thermal expansion 4 × 10 ⁻⁶/℃) | Chitsulo chosapanga dzimbiri chimakhala ndi oxidation pa kutentha kwambiri, pomwe mapulasitiki amakhala ndi kukana kutentha kosakwana 80 ℃. |
| Kukana dzimbiri | Kugonjetsedwa ndi ma asidi amphamvu (concentrated sulfuric acid), maziko amphamvu, ndi chitsulo chosungunula. | Chitsulo chosapanga dzimbiri chimakhala ndi dzimbiri chikakumana ndi ayoni a kloride, pomwe pulasitiki imakhala ndi mphamvu zochepa zolimbana ndi mankhwala. |
| Wopepuka | Kuchulukana kwa 3.0 ~ 3.14 g/cm ³ (60% kupepuka kuposa chitsulo) | Mapaipi achitsulo ndi ochuluka ndipo ali ndi ndalama zambiri zoikamo |
| Kukula kwantchito | Anti static (madulidwe ofooka), ukhondo wa semiconductor grade | Zitsulo zimafunikira chithandizo chowonjezera kuti chiteteze kuphulika, pomwe mapulasitiki amatha kuipitsidwa |
Mwachidule, palibe njira ina yothetsera mapaipi a silicon carbide ponyamula zinthu zowononga kwambiri komanso zosavala ngati phulusa la acidic ndi phulusa la gasi wotentha kwambiri.
Ngati muli ndi mafunso, chonde omasuka kulankhula nafe nthawi iliyonse.
Shandong Zhongpeng Special Ceramics Co., Ltd ndi imodzi mwamayankho akulu kwambiri a silicon carbide ceramic ku China. SiC ukadaulo wa ceramic: Kulimba kwa Moh ndi 9 (Kulimba kwa Moh Chatsopano ndi 13), kukana kwambiri kukokoloka ndi dzimbiri, abrasion yabwino - kukana ndi anti-oxidation. Moyo wautumiki wa SiC ndi 4 mpaka 5 nthawi yayitali kuposa 92% alumina. MOR ya RBSiC ndi 5 mpaka 7 nthawi ya SNBSC, itha kugwiritsidwa ntchito pazinthu zovuta kwambiri. Ndondomeko yobwereketsa ndi yofulumira, yobweretsera ndi monga momwe inalonjezedwa ndipo khalidweli ndi lachiwiri kwa wina aliyense. Nthawi zonse timalimbikira kutsutsa zolinga zathu ndikubwezeranso mitima yathu kwa anthu.
