Ukuqonda indlela yokubala yoxinaniso lwe-refractory castable, yintoni umngxuma womoya?
1. Kukho iintlobo ezintathu zemibhobho:
1. Elinye icala livaliwe kwaye elinye icala linxibelelana ngaphandle, elibizwa ngokuba yi-open pore.
2. I-pore evaliweyo ivaliwe kwisampuli kwaye ayidibanisi nehlabathi langaphandle.
3. Imingxuma ephumela kwimingxuma ibizwa ngokuba yimingxuma.
I-porosity iyonke, oko kukuthi i-porosity yokwenyani, ibhekisa kwipesenti yomthamo opheleleyo we-pores kumthamo opheleleyo wesampulu;Ngokubanzi, umngxuma wokudlula udityaniswe nomngxuma ovulekileyo, kwaye umngxuma ovaliweyo ungaphantsi kwaye unzima ukulinganisa ngokuthe ngqo.Ngoko ke, i-porosity ibonakaliswa yi-porosity evulekile, oko kukuthi, i-porosity ebonakalayo.I-porosity ebonakalayo ibhekisela kwipesenti yomthamo opheleleyo we-pores evulekileyo kwisampuli ukuya kumthamo opheleleyo wesampuli.
Ubuninzi bobuninzi bubhekisela kumlinganiselo womthamo ochithwayo wesampulu eyomileyo ukuya kumthamo wayo opheleleyo, oko kukuthi, umlinganiselo womthamo ogqithisiweyo womzimba we-porous ukuya kumthamo wawo wonke, ochazwe kwi-Kg / m3 okanye i-g / cm3.I-porosity ebonakalayo kunye ne-bulk density sesinye seziseko zokulawula ubuninzi be-refractory castable kulwakhiwo.Izalathisi ezimbini zokusebenza zinokulinganiswa ngesampulu efanayo.Oku kulandelayo kukuxinana kwesambuku kunye ne-porosity ecacileyo yee-refractory castables ezisetyenziswa ngokuqhelekileyo.
2. Oku kulandelayo kukuxinana kwesambuku kunye ne-porosity ecacileyo yee-refractory castables ezisetyenziswa ngokuqhelekileyo.
I-CA-50 yesamente ephezulu ye-alumina enokuchithwa, i-2.3-2.6g / cm3, 17-20

3. Ubuninzi be-cement castable ephantsi kwaziswa ngokufutshane ngezantsi
I-samente ephantsi yokulahla ithatha isamente ye-calcium aluminate njenge-binder, kwaye izinto ezichithwayo ezinomxholo we-CaO ngaphantsi kwe-2.5% zibizwa ngokuba yi-lowcement castables.Ngokwahlukileyo kwi-castables yendabuko, i-cement castables ephantsi ilungiswa ngokutshintshela ininzi okanye yonke i-alumina yesamente ephezulu kunye ne-superfine powder (ubungakanani besuntswana elingaphantsi kwe-microns ezili-10) kunye ne-agglomeration bonding kunye nokubunjwa kweekhemikhali ezifanayo okanye ezifanayo zezinto eziphambili, ukulungelelanisa ubungakanani bamasuntswana. ukusabalalisa, i-micro powder, i-particle shape kunye nezinye izinto, kunye nokongeza inani elincinci le-dispersant (i-water reducer), inani elilinganiselweyo le-retarder kunye nezinye izongezo ezidibeneyo.
Uxinaniso lodongwe olusezantsi lwesamente ekwaziyo ukuqholeka yi-2.26g/cm ³ malunga.
Uxinaniso lwe-alumina ephezulu ephantsi yesamente ekwaziyo ukuqholeka yi-2.3 ~ 2.6g/cm ³ malunga.
I-Corundum yesamente ephantsi erefractory enokugalelwa enoxinano lwe-2.65~2.9g/cm ³ malunga.
