4, the kiln car for being paved with material is finally sent to kiln by supply unit.
Two, the kiln car for being paved with material is burnt into tunnel oven 2, and foamed ceramic light weight board finished product is obtained after firing.
Three, kiln car is after the kiln tail of tunnel oven 2 comes out, and into lower stockline 3, including carries out the lower material list of unloading upper layer saggar First 31A unloads the blanking unit 31C of the blanking unit 31B and unloading bottom saggar of middle level saggar.
It referring to Fig. 5, passes sequentially through the first unloading unit 311 and unloads coaming plate, it is light to unload foamed ceramic by the second unloading unit 312 Lumber downloads backing plate, to dismantle upper layer saggar by third unloading unit 313；
Then, it referring to Fig. 4, passes sequentially through the first unloading unit 311 and unloads coaming plate, foaming is unloaded by the second unloading unit 312 Ceramic light weight board downloads backing plate, to dismantle middle level saggar by third unloading unit 313；
Finally, it referring to Fig. 3, passes sequentially through the first unloading unit 311 and unloads coaming plate, foaming is unloaded by the second unloading unit 312 Ceramic light weight board, to dismantle bottom saggar, 3 end of operation of lower stockline.
With this circulating repetition.
Further, the foamed ceramic light weight board is mainly made of the raw material of following weight percentage:Ceramic polishing is useless Slag 70-96%, clay 0-10%, feldspar 0-20%, foaming agent 0.01-0.6%, stabilizer 0.1-4%.
Preferably, the foamed ceramic light weight board is mainly made of the raw material of following weight percentage:Ceramic polishing is useless Slag 75-95%, clay 0.1-10%, feldspar 0.1-20%, foaming agent 0.1-0.4%, stabilizer 0.1-3%.
Invention increases the additions of ceramic polishing waste residue, while reducing the addition of foaming agent.On the basis of this, add The manganese dioxide stabilizer for entering 0.1-4%, can improve the uniformity of bubble, even if in same section, stomata from top to bottom Indifference so that the whole uniformity of product is good.The stomata of foamed ceramic light weight board entirety section is circular hole, and on to Under pore size it is almost the same, the uniform pore diameter of firing is good.
Manganese dioxide is amphoteric oxide, it is a kind of black powder solid highly stable under room temperature.Meet reducing agent When, oxidisability is shown as, when meeting strong oxidizer, shows as reproducibility.The prior art usually using manganese dioxide as oxidant or Catalyst uses.The present invention is used manganese dioxide as bubble stabilizer, manganese dioxide can by with after the reacting of formula, So that the wall of stomata is toughened up, while keeping the uniformity of formula more preferable, even if indifference if same section hole from top to bottom It is different, it avoids stomata from being crushed, improves the uniformity of bubble, the whole uniformity of product is good.
The foaming agent is silicon carbide or grinding head for polishing reclaimed materials, and the main component of the grinding head for polishing reclaimed materials includes carbon SiClx and resin.Silicon carbide is a kind of expanded material, and the presence of the material makes it in sintering procedure unlike conventional ceramic It shrinks, is expansion instead, to make high-strength light ceramic wafer for building more hold than traditional ceramics plate in size and thickness It is easy to do to big and thick.Grinding head for polishing reclaimed materials is added as substrate raw material, is because grinding head for polishing ingredient itself is exactly silicon carbide And resin, and silicon carbide is exactly the foaming agent added in inventive formulation, so the present invention can subtract the addition of foaming agent As little as 0.01-0.6% reduces the dosage of foaming agent, reduces cost.
Meanwhile the ceramic polishing waste residue of 70-96% is introduced in formula, environment-protective circulating utilization is not only improved, it is also possible that It is internal after the sintering of foamed ceramic light weight board that there is firm similar cellular pore space structure, have environmentally protective, light, square Just it constructs, mitigate the advantages that building load.The addition of ceramic polishing waste residue of the present invention is far longer than existing foamed ceramic plate, Cost is reduced, the recycling to solid waste is reinforced.
The clay is one or more in black mud, kaolin, municipal sludge, ooze.Clay is added in raw material of the present invention And feldspar, silicon, aluminium, potassium, the sodium ingredient ratio in Base Formula can be adjusted, keeps foaming brick wall harder, intensity higher, and further Waste solids are recycled.
