Abstract
The present invention by in batching, add a kind of we be referred to as the natural matter of Kang Shi and the method for the plaster of Paris provides a kind of high strength lightweight silica brick.Corresponding to volume density 1.0g/cm
3, 0.8g/cm
3, 0.6g/cm
3The goods compressive strength be not less than 150kg/cm respectively
2, 80kg/cm
2And 40kg/cm
2, all the other performances are roughly identical with common goods.Thereby expanded the Application Areas of light silicious brick greatly.
Description
The present invention relates to a kind of porous rostone or porous ceramic articles and manufacture method thereof that adds chemical foaming agent.
The normal temperature strength of prior art is all lower, and density is less than 1.0g/cm
3All the more so.For example homemade and Japanese product density 0.96g/cm
3The light silicious brick cold crushing strength be 26kg/cm
2, Japan produces density 1.1g/cm
3The light silicious brick cold crushing strength only be 60kg/cm
2(referring to " various countries' refractory industry outline " of " Encyclopadia Sinica mining and metallurgy " the 525th page and the compiling of Anshan coking refractory materials designing institute the 336th page), this has caused the high breakage rate in the transportation on the one hand, has limited the Application Areas of goods on the other hand greatly.
Task of the present invention is developed a kind of high strength lightweight silica brick exactly, and finds out a kind of simple processing method, enlarges the Application Areas of light silicious brick, reduces the breakage rate in transportation and the use.
For finishing the foregoing invention task, the present invention proposes a kind of technical scheme, promptly in original furnish component, add a kind of we be referred to as the natural matter and the plaster of Paris of Kang Shi.The physicochemical property of Kang Shi is as follows: SiO2 80-97%, Fe2O3 0.1-3%, Al2O3 0.1-11%, plastic index 3-7.Propose this scheme and be based on a kind of like this consideration promptly: Kang Shi not only contains more SiO2 but also contains Fe2O3, multiple metal oxide such as Al2O3, the condition that forms at a lower temperature in conjunction with phase objectively not only is provided, thereby improve the approach of the approach of goods normal temperature strength, and the mineralizer-ferric oxide that promotes the SiO2 conversion is provided again.In addition, the calcium oxide that terra alba decomposites also is good mineralizer, in addition, when this scheme of employing, because of having saved common iron phosphorus and milk of lime preparation process, also can simplify production technique greatly.
Prescription of the present invention is:
Less than 100 order silica fine powder 50-90%(weight)
Less than 100 order Kang Shi fine powder 10-30%(weight)
Add gesso 1-10%(weight)
Add rosined soap 0.05-1%(weight)
Add paper pulp 0.3-3%(weight)
Add gelatine 0.5-3%(weight)
Add alum 0.1-1%(weight)
Preferred prescription is:
Less than 160 order silica fine powder 70-90%(weight)
Less than 120 order Kang Shi fine powder 15-25%(weight)
Add gesso 1.5-6%(weight)
Add rosined soap 0.05-1%(weight)
Add paper pulp 0.3-3%(weight)
Add alum 0.1-1%(weight)
Add gelatine 0.5-2%(weight)
The manufacture method of product of the present invention is:
Slurry preparation: take by weighing the silica fine powder in prescription institute to ratio, add behind the Kang Shi fine powder and the plaster of Paris water be stirred to degree Beaume be 1.5-3.5 qualified mud.
Foam preparation: take by weighing rosined soap in prescription to ratio and place in the whisking machine, add this weight 3-8 warm water startup whisking machine doubly and got final product in 2-7 minute.
Foam mud preparation: with paper pulp gelatine, alum solution adds in the qualified mud that makes, and adds qualified foam again and together stirs and got final product in 2-8 minute.
Moulding: adopt casting, attention will be stirred out air pocket.
Dry: as to be dried to moisture content and to be lower than 0.5%.
Burn till: maximum sintering temperature is 1360-1380 ℃.
Last machining and shaping gets product.
Finished the invention task by this programme.Making the finished product cold crushing strength is: volume density 1.0g/cm
3Be not less than 150kg/cm
2, volume density 0.8g/cm
3Be not less than 80kg/cm
2, volume density 0.6g/cm
3Be not less than 40kg/cm
2
The product composition scope that makes as stated above is: SiO275-96%, and Fe2O30.5-2.5%, CaO1-6%, goods height sintering, other performance index are identical with existing common light silicious brick substantially.
In view of intensity of the present invention is very high,, it bore the pressure effect so not only having can be used to outer heat insulation masonry heat insulation but also that can be used to build by laying bricks or stones Thermal Equipment.Can enlarge the Application Areas of light silicious brick greatly.
Three embodiment of the present invention: the manufacturing example and the performance comparison of the high strength and light weight Si bricks of three different densities.
Make prescription by weight percentage:
Example 1: the high strength and light weight Si bricks of making 100kg density 0.6
Slurry preparation: take by weighing 85kg less than 160 purpose silica fine powders in last table to ratio, 15kg is less than 120 purpose Kang Shi fine powders, and the 4kg gesso places mixing machine, adds that to be mixed into degree Beaume behind the water be till 1.8.
Foam preparation: take by weighing rosined soap 0.2kg in last table institute to ratio and place and add 40 ℃ of warm water 1.2kg in the whisking machine, start whisking machine then and promptly made qualified foam in 4 minutes.
Foam mud preparation: with 1kg paper pulp and by 1kg gelatine, the 0.5kg alum back gained solution that is dissolved in water places in the qualified mud of stirrer, adds above-mentioned qualified foam again, stir pour out after 4 minutes stand-by.
Moulding: in the swage with above-mentioned qualified foam mud injection 300 * 150 * 100, stir out air pocket in it with the iron fork.
Dry: as to fall the swage that fills foam mud and send into the tunnel dryer inner drying of 110 ℃ of temperature ins to moisture＜0.5%.
Burn till: the blank after the demoulding is sent into tunnel furnace burn till, maximum sintering temperature 1360-1380 ℃.
Being processed into 280 * 130 * 80 finished product after burning till again with a chainsaw can pack and dispatch from the factory.
Example 2 is identical with example 1 with example 3 manufacture method
The performance synopsis of the together domestic and international currently available products of above-mentioned three routine performances:
