I-Refractory Cement & Mortar

Incazelo emfushane:

Udaka lwe-Refractory, owaziwa nangokuthi udaka lomlilo noma izinto ezihlangene (impuphu), esetshenziswa njengemikhiqizo yokubopha izitini zezinto zokwakha, ngokusho kwezinto zingahlukaniswa zibe ubumba, i-aluminium ephezulu, i-silicon kanye nodaka lwe-magnesium refractory, njll. eyenziwe ngempushana ye-refractory clinker kanye nobumba lwepulasitiki njenge-binder ne-ejenti yepulasitiki.Amandla ayo ekamelweni lokushisa aphansi, futhi ukwakheka kwe-ceramic bonding ekushiseni okuphezulu kunamandla amakhulu.

Incazelo

I-Refractory mortar iyimpahla ehlanganyelwe esetshenziselwa ukwakha imikhiqizo ephikisayo enomumo.Yakhiwe ngempushana ephikisayo, amanzi noma i-liquid binder kanye nezixube (njenge-dispersant plasticizer, stabilizer noma i-ejenti yokugcina amanzi).I-slurry efana nokunamathisela (noma ukumiswa okuminyene) okuqukethe ukugxila okuphezulu kwezinhlayiya eziqinile, ezinezici zoketshezi lwe-Bingham.Isilinganiso sesisindo esiqinile/esiwuketshezi sicishe sibe (70~75)/(30~25) futhi isilinganiso somthamo oqinile/owuketshezi siyahlukahluka ngokudonsela phansi okuthile kwempushana ephikisayo, cishe (35~50)/(65~50).Ngokuvamile, isetshenziswa nge-spatula.

 

Ukwahlukanisa

Udaka lwe-Refractory, owaziwa nangokuthi udaka lomlilo noma izinto ezihlangene (impushana), ezisetshenziswa njengezinto zokubopha izinsimbi ze-brickwork, ngokusho kwezinto ezibonakalayo zingahlukaniswa zibe ubumba, i-aluminium ephezulu, i-silicon ne-magnesium refractory mortar, njll.

Kubizwa ngokuthi udaka olujwayelekile lwe-refractory olwenziwe ngempushana ye-refractory clinker kanye nobumba lwepulasitiki njenge-binder kanye ne-ejenti yepulasitiki.Amandla ayo ekamelweni lokushisa aphansi, futhi ukwakheka kwe-ceramic bonding ekushiseni okuphezulu kunamandla amakhulu.

Nge-hydraulic, ukuqina komoya noma izinto eziqinisa i-thermo njenge-binder, okubizwa nge-chemical binding refractory mortar, njengoba ngezansi kokwakheka kwezinga lokushisa elibophezelayo le-ceramic ngaphambi kokukhiqizwa kokusabela kwamakhemikhali okuthile kanye nokuqina.

Izici

Izici zodaka lwe-Refractory: ipulasitiki enhle, ukwakhiwa okulula;amandla esibopho esiphezulu, ukumelana nokugqwala okuqinile;i-refractoriness ephezulu, kufika ku-1650 ℃ ± 50 ℃;ukumelana okuhle kokuhlasela kwe-slag;impahla enhle yokushisa eshisayo.

Isicelo

Udaka lwe-Refractory lusetshenziswa kakhulu kuhhavini we-coke, ingilazi yomlilo, isithando somlilo, isitofu esishisayo, i-metallurgy, imboni yezinto zokwakha, imishini, i-petrochemical, ingilazi, ibhoyili, amandla kagesi, insimbi nensimbi, usimende nezinye iziko lezimboni.
