Sibidhka Dib-u-Celinta & Sawirka Hoobiyaha

Sibidhka & Hoobiyaha

Sharaxaad Gaaban:

Hoobiye refractory, sidoo kale loo yaqaan hoobiye dabka ama walxaha wadajirka ah (budada), loo isticmaalo sida bonding alaabta refractory alaabta lebenka, sida laga soo xigtay wax waxaa loo qaybin karaa dhoobo, aluminium sare, Silicon iyo magnesium hoobiye refractory, iwm Waxaa loo yaqaan hoobiye refractory caadiga ah. oo laga sameeyay budada clinker-ka iyo dhoobada caaga ah sida binder iyo wakiil caag ah. Xooggeeda heerkulka qolka waa hooseeyaa, iyo samaynta isku-xidhka dhoobada ee heerkulka sare ayaa leh awood sare.

Sharaxaada

Hoobiyaha refractory waa walxo wadajir ah oo loo isticmaalo in lagu dhiso alaabada refractory ee qaabaysan. Waxay ka kooban tahay budada refractory, biyo ama dareere dareere ah iyo isku darka (sida balaastiga kala firdhiya, xasiliyaha ama wakiilka biyaha celiya). Dheecaan u eg koollo (ama ganaax qaro weyn) oo ay ku jiraan uruurin sare oo ah qaybo adag, kuwaas oo leh sifooyinka dareeraha Bingham. Saamiga miisaanka adag / dareeraha wuxuu ku saabsan yahay (70 ~ 75) / (30 ~ 25) iyo saamiga mugga adag / dareeraha wuxuu ku kala duwan yahay cufnaanta gaarka ah ee budada refractory, qiyaastii (35 ~ 50) / (65 ~ 50). Guud ahaan, waxaa lagu dabaqaa spatula.

Kala soocidda

Hoobiye refractory, oo sidoo kale loo yaqaan hoobiye dabka ama walxaha wadajirka ah (budada), loo isticmaalo sida isku xidhka alaabta refractory alaabta lebenka, sida ku cad walxaha waxaa loo qaybin karaa dhoobo, aluminium sare, Silicon iyo magnesium hoobiye refractory, iwm.

Waxaa loo yaqaan hoobiye dib-u-celinta caadiga ah oo laga sameeyay budada clinker-ka-celinta iyo dhoobada caagga ah sida xiraha iyo wakiilka caagga ah. Xooggeeda heerkulka qolka waa hooseeyaa, iyo samaynta isku-xidhka dhoobada ee heerkulka sare ayaa leh awood sare.

Iyada oo leh hydraulicity, hawo engegnaanta ama qalabka kulayl-adag sida xidhe, loo yaqaan kiimikaad ku xidhka hoobiye refractory, sida ka hooseeya samaynta heerkulka xidhitaanka dhoobada ka hor wax soo saarka ee falcelin kiimikaad gaar ah iyo qallafsanaan.

Astaamaha

Sifooyinka hoobiyeyaasha refractory: caag wanaagsan, dhismo ku habboon; xoogga dammaanadda sare, iska caabin daxalka xooggan; refractority sare, ilaa 1650 ± 50 ℃; iska caabin weerar oo wanaagsan; hantida spalling kulaylka wanaagsan.

Codsiga

Hoobiyaha refractory waxaa inta badan loo isticmaalaa foornada kookaha, foornada dhalada, foornada qaraxa, kariyaha kulul, biraha, warshadaha walxaha dhismaha, mishiinada, kiimikaalka batroolka, dhalooyinka, kuleyliyaha, korontada, birta iyo birta, sibidhka iyo foornada kale ee warshadaha.
