Two of object of the present invention is to provide a kind of preparation method of black pottery plate.
In order to realize foregoing invention object, processing method of the present invention comprises the following steps:
(1), by proportioning, get the each raw material except softening agent described in technique scheme one or two and by more than each raw material pulverizing to 250 order, the then each raw material formation mixing raw material after co-grinding;
(2) account for the proportion relation of the 15.5-18.5% of mixing raw material quality by water, mixing raw material, softening agent and water are mixed in stirrer, thereby make wet feed;
(3) above-mentioned wet feed is sent into pug mill carry out mixing, thereby make the pug that plasticity index is 8-12;
(4) above-mentioned pug is sent into vacuum-extruder and carry out moulding through die orifice, then cut into the specification that meets design requirements, thereby make wet base substrate;
(5) will wet base substrate under temperature 120-150 DEG C condition, dry 4-8 hour, thus make dry tenacity and reach the dry body body of 1.5-3.5Mpa;
(6) dry body body is sent in calcining kiln, under temperature 1100-1140 DEG C condition, after 2.5-5 hour burns till, just made black pottery plate.
Described in the present invention in raw material, softening agent is that modified starch is the binding agent that is dry mixed of main component, for example can adopt this product of Guangdong Feng Lin glaze company production, can certainly adopt the like product of other producer, softening agent plays increases plasticity and lubricated effect; Wilkinite, kaolin, clay, granite building material waste residue are pottery board substrate material; Tailings in vanadium extraction, manganese ore are body material and chromonic materials.
The equipment such as the present invention's stirrer used, pug mill and pulverizer, are all currently available products.
The invention has the advantages that: utilize low cost iron and steel enterprise waste material tailings in vanadium extraction for main raw material and as color development raw material, add the waste residue powder of clay and granite building material industry cheaply, the black pottery plate that can produce different form and aspect according to addition difference, quality product is high, cost is low, energy consumption is low.
