Bear "Customer initially, High Quality first" maskaxda ku hay, waxaan si dhow shaqada si dhow ula macaamiisheena iyo siin iyaga la hufan iyo bixiyeyaasha xirfad u saaraha of China High Manganese Steel Casting Graphite Ingot caaryada Supplier, Iyada oo kala duwan, tayada sare, heerka macquulka ah iyo designs stylish, our alaabta waxaa si ballaaran loo isticmaalo la warshadaha iyo kuwa kale.
Maskaxda ku hay "macmiilka marka hore, marka hore tayadiisu sarreyso", waxaanu si dhow ula shaqaynaa macaamiisheena waxaanu siinaa bixiyeyaal hufan oo xirfad lehChina Ingot Mold for Birr Mill, Ductile Iron Ingot MoldFalsafada Ganacsiga: U qaado macmiilka Xarunta, u qaado tayada nolosha, daacadnimada, masuuliyada, diiradda, hal-abuurka
Kaarboon / kaarboon isku-dar ah(ka dib loo tixraaco "C/C ama CFC”) waa nooc ka mid ah walxaha isku dhafan kaas oo ku salaysan kaarboon oo lagu xoojiyay fiber carbon iyo alaabteeda (kaarboon fiber preform). Waxay leedahay labadaba firfircoonida kaarboonka iyo xoogga sare ee fiber carbon. Waxay leedahay sifooyin farsamo oo wanaagsan, caabbinta kulaylka, iska caabinta daxalka, qoyaanka xoqida iyo sifooyinka kulaylka iyo korantada
CVD-SiCdaahan wuxuu leeyahay sifooyinka qaab-dhismeedka lebis, wax is haysta, iska caabin heerkulka sare, iska caabin oksaydhka, daahirsanaan sare, caabbinta acid & alkali iyo reagent organic, leh guryaha deggan iyo kiimikaad.
Marka la barbar dhigo qalabka garaafyada sare ee nadiifka ah, graphite wuxuu bilaabaa inuu oxidize at 400C, taas oo keeni doonta luminta budada sababtoo ah oksaydheynta, taasoo keentay wasakhowga deegaanka ee aaladaha durugsan iyo qolalka faakuumka, iyo kordhinta wasakhda deegaanka saafiga ah.
Si kastaba ha noqotee, daahan SiC wuxuu ilaalin karaa xasilloonida jirka iyo kiimikaad ee 1600 darajo, Waxaa si weyn loogu isticmaalaa warshadaha casriga ah, gaar ahaan warshadaha semiconductor.
Shirkaddayadu waxay bixisaa adeegyada habka daahan SiC by habka CVD on dusha graphite, ceramics iyo alaabta kale, si gaas gaar ah oo ay ku jiraan kaarboon iyo Silicon falgal heerkulka sare si ay u helaan daahirsanaan sare SiC molecules, molecules kaydin dusha alaabta dahaarka ah, samaynta lakabka ilaalinta SIC. SIC-ga la sameeyay waxay si adag ugu xidhan tahay saldhigga garaafka, iyadoo siinaya saldhigga garaafyada sifooyin gaar ah, sidaas darteed samaynta dusha sare ee garaafka, Porosity-free, caabbinta heerkulka sare, caabbinta daxalka iyo caabbinta oksaydhka.
Tilmaamaha ugu muhiimsan:
1. Iska caabbinta oksaydhka heerkulka sare:
caabbinta oksaydhisku weli aad bay u wanaagsan tahay marka heerkulku uu gaadho 1600 C.
2. Nadiifin sare: oo ay samaysay uumiga kiimikaad ee hoos yimaada xaalada koloriinaynta heerkulka sare.
3. Iska caabinta nabaadguurka: adkaanta sare, dusha sare, qaybo yaryar.
4. Iska caabinta daxalka: acid, alkali, milix iyo reagents organic.
