Abstract
A kind of forming method whole process of black ceramic plate of architectural decoration comprises that (1) ingredient inspection (2) batching (3) pulverizes (4) and stir (5) filter mud (6) old (7) puggings (8) cutting (9) extrusion moldings (10) dry (11) and burn till (12) polishing check; The present invention has mechanize, serialization degree height, and labour intensity is little, labour productivity height, the advantage that product percent of pass is high; The high-grade construction decoration material that " black ceramic plate " that present method is produced is a kind of hardness height, thin thickness, color is shiny black, glossiness is high.
Description
The invention belongs to the forming method of porcelain finishing material for building, the forming method of more definite a kind of black ceramic plate used in building decoration of saying so.
The black decorative porcelain is a kind of high-grade finishing material, and it is mainly used in decorative wall, floor and puts the platform of instrument; Sometimes also available its unit's of manufacturing famous brand.
The forming method of porcelain decorative sheet mainly contains two kinds at present:
1. slip casting: the main drawback of this kind method is: (1) takes up an area of many, needs the gypsum mold amount big, (2) are interrupted production technique, manual operations is many, the production cycle long, labour intensity greatly, labour productivity and product percent of pass be all low.
2. shaping method to suppress: the shortcoming of this kind method is that product percent of pass is low.
Task of the present invention be study that successfully a kind of production technique mechanize serialization degree is higher, labour intensity is little, floor space is little, labour productivity and all high processing method of manufacturing the black decorative porcelain of product percent of pass.
Content of the present invention:
Accompanying drawing is a process flow sheet of the present invention.With reference to accompanying drawing that detailed description of the present invention is as follows:

2. prepare burden:
To prepare burden by following prescription through " ingredient inspection " qualified raw material; Batching error requirements≤± 5%,
Prescription: tailings in vanadium extraction: 65%, clay: 11%, talcum powder: 3%, bowl kiln hood soil: 11%, laterite: 10%.
3. pulverize:
In 1.5 tons of ball mills of packing into of qualified batching that will transfer from " batching ", then in material: ball: the ratio of water=1: 2: 1.8 adding ballstone and water in the ball mill.After adding, start ball mill again, its rotating speed is controlled in 23 ± 2 rev/mins of scopes.Material is pulverized.When the pulverizing time reaches 10 ± 0.5 hours, it is stopped operating, will pulverize and expect that storage was good standby behind 80～120 mesh sieves.
4. stir:
To put into suction pit by the qualified mud that " pulverizing " transfers, even in order to make pug, in suction pit with stirrer stir be no less than 20 minutes after, stop to stir, mud has stored up standby.
5. filter mud:
The mud that " stirring " is good carries out press filtration with pressure filter, is qualified mud cake when moisture content is 20 ± .5%.
6. old:
To send into room temperature from the qualified pug that " filter mud " transfers is to carry out " old " 20-35 ℃ the pug worker-house, and after the old time reached 24-48 hour, pug can change down and uses.
7. pugging:
To put into " vacuum deairing machine " that vacuum tightness is 750 ± 10 millimeter water column through " old " qualified pug, and pug be carried out " pugging " handle twice.
8. cutting:
To handle qualified pug through " pugging ", with " single-lead-screw extruding briquetting machine knife plate cutter " on request size (general requirement cut into 600 millimeters rectangular) cut.
9. extrusion molding:
The strip pug that " cutting " is good, by being that 280 millimeters rollers of φ are formed by diameter, rotating speed is 3 meter per seconds " two roll presses ", through after four compactings more in accordance with regulations size (general base substrate dimensional requirement is: length * wide * thick=605 ± 5 * 404 ± 5 * 11 ± 2 millimeter) cut, promptly get " base substrate " of manufacturing black ceramic plate.
10. dry:
" base substrate " of " extrusion molding " sent in the oven dry road, and dry under 40 °～60 ℃ temperature 〉=48 hours, dried " base substrate " requires not ftracture moisture content≤4%.
11. burn till:
Qualified " base substrate " that drying is good sent in 42 meters long " coal electricity mix roller kiln " and burnt till, and top temperature is 1060～1100 ℃ in the kiln, and firing time is 108～120 minutes; " base substrate " after burning till requires to be forbidden that cracking is arranged, gives birth to defectives such as burning, burning and bubble.
12. the qualified product after will " burning till ", polish by polishing machine again, the polishing time is five minutes, and the product behind the mill is tested by DB/3707 Q32001～88 specified standardss, is " decorate and use black ceramic plate " that the present invention will manufacture through goods after the assay was approved.
" decorate and use black ceramic plate " that the present invention is made, its shape is regular, be rectangle, the quality exquisiteness, look black, and hardness (Morse) is that 8(is higher by 2 than artificial granite stone), glossiness is (stonite's glossiness is 60 degree) more than 80 degree, surface-brightening is like mirror, thereby porcelain decorative plate is a kind of ideal flawless finish material of construction.
The present invention has following advantage and characteristics:
1. mechanize of the present invention, serialization degree height has been saved large quantities of labor forces.
Because of whole process of the present invention is mechanize and serialization production substantially, therefore large quantities of labor forces have been saved, for example: produce 40000 meters per year
2Black porcelain plate can be saved 50 people.
2. alleviate labour intensity, improved labour productivity:
Because of each operation of the present invention realizes power operation substantially, so that the operator from the manual work of heaviness, free.Also because of the present invention has realized mechanize substantially, serialization production so shortened the production cycle, has improved labour productivity.
For example: it is 1/3～1/4 of shaping method to suppress that the present invention whenever manufactures a used time of black ceramic plate.The present invention manufacture 1 used time of black ceramic plate only be " slip casting " 1/60.
3. improved product percent of pass
Product percent of pass of the present invention is up to more than 80%, and the product percent of pass of " slip casting " is only 70%, and the product percent of pass of " shaping method to suppress " is 75%.
4. the present invention is taken up an area of less, can save a large amount of gypsum molds.
To produce 40000 meters per year
2The production line of black ceramic plate is an example, and main worker-house of the present invention takes up an area of 450 meters
2, " slip casting " main worker-house takes up an area of 700 meters
2, " shaping method to suppress " main worker-house takes up an area of 600 meters
2; Use the present invention can save more than 1000 gypsum mold.
