So, the porosity that how can just reduce tall aluminous brick appears particularly important. By Zhengzhou flourish next Cheng Naicai introduces how to reduce the porosity of tall aluminous brick for you.
1, to reduce the porosity of tall aluminous brick, zhengzhou flourish Cheng Naicai first from raw material choose, burden, till shape,mix, firing each working procedure should take corresponding step. Low porosity raw material or product are simple to improving a product the quantity, mechanical strength that improves product, decrease to be accumulated with the surface of slaggy contact, prolonging service life is beneficial.
2, the bibulous rate of tall aluminous aluminous grog is the one course that Zhengzhou flourish Cheng Naicai chooses be less than 5% , 2 class tall aluminium expects bibulous rate is be less than 7% for. Be less than water content next the soft qualitative clay of 4% and aluminous aluminous grog mix fine grind. Mix fine crocus burden with this kind, can reduce adobe porosity.
3, the grain grading when burden of Zhengzhou flourish Cheng Naicai, thick in fine than be 4:2: 4, big grain should not exceed 5mm. The order of feed in raw material when batch mixing is as follows: Join thick grain first, rejoin sulphurous acid mixes 3min beforehand after pulp waste liquid, fine pink of rejoin tall aluminium undertakes mixture. Forbidden thick, fine grained makings is joined at the same time grind inside the unit operation of cargo handling that adds waste liquid of sulphurous acid pulp again.
4, to reduce porosity, flourish Cheng Naicai will be bosseyed pressurization instead is double-faced pressurization instead is double-faced pressurization, blow number also differs according to quantity of feed in raw material and different. If use blaze pit firing, should adjust the position of aperture suction internal heat, make mid close, brim is rare, and close wicket place is added appropriately close, make difference in temperature of difference in temperature of kiln furnace fluctuation, inside and outside is not more than 20 degrees.
Zhengzhou flourish Cheng Naicai needs according to what differ, measure the service with custom-built and different body. Manage a concept with the enterprise of guileless: "Yield profit rather, do not allow the market. Allow the market rather, do not lose credit " , face the expectation of market demand and client. Excelsior, achieve trade high-quality goods to serve power industry diligent act vigorously is entered, with devotional manner, pursuit is better, the satisfaction that lets you makes our joy. If you have the demand of the tall aluminous brick of low porosity, the welcome calls Zhengzhou flourish Cheng Naicai.
