Lub blast furnace plua plav npog yog hnyav corroded los ntawm cov kua qaub thiab alkali, yog li nws yog qhov zoo dua los siv hnav-resistant semi-hnav.refractory gunning mix.
1. Cov tshuaj pleev xim rau lub teeb muaj qhov sib txawv ntawm lub cev.
Lub teeb yuag refractory spray gunning mix muaj qhov sib txawv ntawm lub cev. Yog hais tias lub cev ntom ntom dhau lub teeb, nws yuav tsis hnav-resistant. Yog hais tias lub ntom ntom dhau lawm, qhov hnyav ntawm cov plua plav collector yuav hnyav dhau. Lub npe hu ua lub teeb yuag txheej txheej yog los ua lub luag haujlwm ntawm thermal rwb thaiv tsev thiab hauv ob sab phlu, tab sis nws yuav tsum hnav thiab hnav-tiv taus. Nws yog semi-light spray txheej. Nws yuav tsum tsis tsuas yog ua si lub luag hauj lwm ntawm thermal rwb thaiv tsev, tab sis kuj yuav hnav-resistant thiab corrosion-resistant. Nws yuav tsum tau ua los ntawm cov khoom ntom ntom. Cov xim pleev xim yog nyob nruab nrab ntawm 1.5-1.7, thiab lub cev ntom ntom ntawm 1.5-1.7 yog cov khoom siv lub teeb.
Lub teeb hnyav hnav-resistant tshuaj tsuag xim kuj yog ib qho kev siv tshuaj tsuag. Txawm li cas los xij, yog tias koj xav tau hnav-tiv taus, corrosion-resistant, thiab muaj qhov ntim zoo ruaj khov, koj yuav tsum siv ultra-nplua hmoov thev naus laus zis los ntawm kev sib txuas ntawm cov cement. Qhov sib ntxiv ntawm ultra-nplua hmoov tuaj yeem ua rau cov tshuaj tsuag Qhov kub-kub ntim ntawm cov txheej yog ruaj khov thiab nws tsis kam rau cov kua qaub thiab alkali yaig kuj zoo tuaj.
2. Dab tsi yog cov khoom siv rau refractory gunning mix?
Muaj ntau yam khoom siv rau cov tshuaj tsuag phom sib xyaw, suav nrog cov cement-bonded, silica-sol-bonded, thiab aluminium-sol-bonded. Txawm li cas los xij, nyob ntawm qhov chaw thiab qhov kub thiab txias siv, kev sib xyaw ua ke kuj txawv. Tam sim no, ntau cov nroj tsuag loj loj siv silica sol-bonded linings rau blast furnace linings, thiab lawv cov kev xav tau ceev yog siab. Thiab yog tias nws yog lub qhov cub kub kub uas muaj qhov ntom ntom ntom ntom ntawm 2.0, nws yog khi nrog cov cement.
3. Lub chimney hauv ob sab phlu feem ntau yog ib lub teeb hnyav acid-resistant refractory gunning mix
Feem ntau, cov tshuaj tsuag txheej siv rau cov kab hluav taws xob hauv lub qhov hluav taws xob yog qhov zoo ib yam li cov uas siv rau lub tshuab hluav taws xob blasting plua plav hoods. Semi-lightweight spray gunning mix feem ntau yog siv vim corrosive cua nyob rau hauv lub chimney yog acidic, yog li semi-light acid-resistant spray coatings yog siv, uas kuj yog ntom. Nruab nrab ntawm 1.5-1.7.
Cov plua plav npog ntawm lub qhov cub tawg muaj ob qho tib si acid thiab alkali Cheebtsam, yog li lub teeb xim pleev xim xaiv yuav tsum tiv thaiv kev yaig ntawm ob qho tib si acid thiab alkali Cheebtsam. Tom qab ntawd qhov hnav tsis kam yog qhov tseem ceeb heev, thiab cov khoom siv sab hauv yuav tsum muaj cov kua qaub thiab alkali tsis kam.
Txhawm rau ua kom tiav, nws yog qhov tsim nyog los siv cov hnav-resistant hnav-resistant refractory spray gunning mix nrog semi-light acid thiab alkali-resistant Cheebtsam rau lub moj tej tawg cub tawg plua plav npog.
