zolimba zasungunuka

Silicon Carbidendi chida chosafunikira chosungunuka mu ma metallical. Chifukwa cha kutentha kwake kwakukulu ndi mawonekedwe owonda, kumagwiritsidwa ntchito kwambiri m'matsulo osiyanasiyana achitsulo ndi mankhwala. Komabe, kuwonetsetsa kuti mukugwiritsa ntchito nthawi yogwiritsa ntchito, yicnon carbides amafunika kukhala okonzekerera bwino.

Kutsatsa misempha ya sic
Silicon Carbidenties amafunikira chisamaliro chapadera pakupanga zitsanzo kuti zithetse mavuto monga kuwonjezeka kwa matenthedwe, kusokoneza pansi kapena kuwonongeka chifukwa cha chinyezi chotsadwa. Njira zenizeni zili motere:

Kuphika koyambirira: Kuphika mu uvuni osawonjezera chilichonse, ndikumasunga kutentha kwa maola opitilira 24. Panthawi imeneyi, gwiritsitsani chovuta pafupipafupi kuti muwombere motenthedwe komanso kuchotsa chinyezi kuchokera kumakoma a chopakacho.

Pang'onopang'ono kutentha:

Choyamba kunamupangitsa kuti Celpius agawidwe ndi 200 mpaka 200 Celsius ndi kugwira 1 ora.
Kenako, onjezerani kutentha pamlingo wa madigiri 150 Celsius pa ola mpaka kutentha kwambiri kumafika. Panthawi imeneyi, pewani kusiya makoma oponderezedwa pakati pa 315 ndi 650 digiri Celsius nthawi yayitali, pomwe wopachikidwayo adzasiyitsa mpweya mwachangu, kufupikitsa moyo wake ndikuchepetsa mawonekedwe ake.

Chithandizo Chachikulu:

Patsamba utamalizidwa, pokhapokha ngati zopachikidwayo zimadziwika bwino, siziyenera kupasukanso ndipo zimatha kupitilizabe kugwiritsidwa ntchito.
Kutsatsa kumamalizidwa, kumadzutsa msanga mpaka 850 ~ 950 madigiri Celsius, kumatentha theka la ola popanda kuwonjezera kutentha ndikuyamba kuwonjezera zida. Chithandizo ichi chimatha kukulitsa moyo wa Utumiki wa pa ntchito.

Njira zina zokonzekera
Kuphatikiza pa njira zomwe zili pamwambazi pamwambapa, njira zotsatirazi zingagwiritsidwenso ntchito:

Preheat pafupi ndi Bullner Wotentha: Kuyika Chopachikidwa pafupi ndi Burner woyaka mafuta angathandize kuchotsa chinyezi.
Makala owotcha kapena mtengo: Makala owotcha kapena nkhuni m'chiwopsezo chomwe chingathandize kuchotsa chinyezi.

Kusankha kukula koyenera
Malire a Silicon Carbide amasiyanasiyana kutengera wopanga ndi pulogalamu inayake. Chifukwa chake, mukamasankha, chonde onaninso zopanga kapena funsani wogulitsa kuti amve zambiri. Kusankha zopambana kutengera zosowa zanu kungakulitse bwino ntchito yopanga zinthu.

Potsatira njira zolondola komanso zowongolera, zolimba za Sicon Carbide zimatha kukulitsa magwiridwe awo ndikuwonjezera moyo wawo wautumiki, kupereka chitsimikizo chodalirika pazopanga.

Graphite Courcial Wogwiritsa Ntchito
Ziwawa zojambula zimagwiritsidwanso ntchito kwambiri pakuyesa kwa kutentha ndi mafakitale. Kutentha Kwake Kwambiri Kukana, kukana kutukuza, komanso kusachita bwino kumapangitsa kuti zikhale zabwino pa zoyeserera ndi njira zambiri. Pofuna kuonetsetsa kuti moyo wabwino kwambiri komanso moyo wautali wa Graphite wochita bwino, magawo otsatirawa ayenera kulabadira pakugwiritsa ntchito:

Kuyika kwachitsanzo
Zitsanzo Zolimba: Ngakhale kuti zina zoyeserera kapena zopangira mu graphite zolimba popewa kuwononga kapena kuwuma.
Zitsanzo zamadzimadzi: Gwiritsani ntchito dontho kapena chida china chaching'ono cha ma micro-stipling kuti muponyere madzi mu chipamwamba popewa kuwaza kapena kuipitsa kunja kwapachilengedwe.

Kutentha
Njira yotentha:

Gwiritsani ntchito zida zotenthetsera magetsi, kuwotcha kwa radiation yofiyira kapena njira zina zotenthetsera zowotcha graphite zothandiza.
Pewani kutentha mwachindunji ndi lawi lotseguka. Chifukwa graphite yayikulu imakhala ndi mawonekedwe othamanga kwambiri, kutenthetsa mwachindunji ndi lawi lotseguka kungapangitse kuti wopaka kapena wosweka.

Kuthamanga Kuthamanga:

Khalani ndi chiwongola dzanja choyenera kuti mupewe kuwononga mphamvu chifukwa chosintha mwadzidzidzi.
Sinthani udindo ndi mphamvu ya chipangizo chotenthetsera kuti muwonetsetse kuti wopachikidwayo watola kwambiri.

Kusamalitsa
Pewani kulumikizana mwachindunji ndi lawi: mukamatenthetsa, pewani kulumikizana mwachindunji ndi lawi kuti musachotse zitsamba zakuda kapena zowonongeka zina.
Kuwongolera kutentha: Graphite yolimba imakonda kusintha kwa kutentha, kotero kutentha kutentha kuyenera kulamulidwa pakugwiritsidwa ntchito popewa kung'ambika chifukwa cha kutentha kwambiri kapena kutentha kwambiri.
Kuyera Kwachilengedwe ndi Chitetezo: Kusunga malo ozungulira ndipo pewani kuwonongeka kwa graphite yomwe ikuchitika chifukwa kapena kugwa kuchokera kutalika.

Thandizo la Dongosolo
Zochita zamagetsi: Zochita zamatenthedwe za graphi yamtengo wapatali kwambiri ndizokhudza 100- 300 w / mu · k, zomwe zimapangitsa kuti zisanduke kutentha pang'onopang'ono ndikuchepetsa mphamvu ya kutentha kwapamwamba.
Kutentha Kwazithunzithunzi: Kukhazikika kwabwino kwambiri, kutentha kogwiritsa ntchito bwino kumatha kufikira 3000 ° C, ndipo amagwiritsidwa ntchito bwino mumlengalenga.
Kukaniza kwa oxidation: mukamagwiritsidwa ntchito kutentha kwambiri mlengalenga, pamtunda wa graphite kumangokonda kukhala oxidation. Njira zoteteza monga kugwiritsa ntchito anti-octidation yokutidwa kapena kugwiritsa ntchito chitetezo cha mpweya kuyenera kutengedwa.

Kutsatira mosamalitsa njira zomwe tafotokozazi ndi mosamala zitha kuwonetsetsa kuti njira yothandizira kwambiri komanso yautali ya zojambulajambula ndiSilicon Carbides, pongopititsa patsogolo kudalirika komanso luso loyesa ndi kupanga.
