After tested, furniture manufacturing of the present invention with tempering pottery physical property is: bulk density 〉=2.85g/cm3, cold crushing strength 〉=230MPa, Mohs' hardness 〉=7 grade, strength at normal temperature 〉=120MPa, fracture toughness 〉=1.0MPam1/2.
The process for making of tempering of the present invention pottery furniture is: raw material-batching-ball milling-deironing-sieve-spray-drying-granulation-old-isostatic compaction-pick-repair-burn till-check-pack warehouse-in-making furniture.
Furniture of the present invention is with the preparation method of tempering pottery: adds various main materials, additional material, auxiliary material in the ball mill in proportion and adds an amount of water and carry out ball milling and form compound,
Compound is ground to 250-300 purpose fineness forms mud, mud is put into equipment for removing ferric ion, get rid of irony and its oxide, again mud is sieved, guarantee to remove not levigate various raw materials and impurity iron, the mud that sieves after the deironing is gone into the spraying granule drying equipment by force feed, make powder particle slyness, good fluidity, the dry powder that bulk density is big is again with the dry powder classification of different fineness, the mould of packing into after old 24-48 hour is transported to equal pressing equipment, base substrate is made in extrusion modling, and base substrate is sent into kiln after the preheating and drying typing, form through 1380-1580 ℃ high-temperature roasting system.
Utilizing above-mentioned tempering ceramic preparation to can be made into thickness is that 2～20mm, size are that following sheet material of 1200 * 3000mm and cross section are that 10 * 10～50 * 50mm, length are the following section bar of 3000mm etc.
Described furniture kind comprises desk, office chair, conference table, desk, desk, tablet chair, bookcase, wine cabinet, wardrobe, dresser, cabinet, tea table, bed, sofa, dining table, dining chair, bin, built-in wardrobe, cabinet for TV, artistic cabinet, computer desk, bathroom cabinet, bedside cupboard, dressing table, writing desk, file cabinet, door and window, shoe chest, hanging cupboard, stair and fitting-up sheet material and section bar.
The present invention is on existing ceramic material basis, by adjusting raw material and improving manufacture method, give full play to aluminium oxide intensity height under the normal temperature, the characteristics of the big and transformation toughening of zirconia toughness, produce a kind of waterproof that not only has, fire prevention, antifouling, indeformable, nondiscolouring, do not ftracture, acid and alkali-resistance is corrosion-resistant, radiationless, and has high strength, high tenacity, the tempering pottery that machine-shaping and cutting performance are good, replace timber with the tempering pottery, aluminium, steel, safety glass, bamboo rattan and plastics are made furniture, it is the new technology in the furniture manufacturing process, both open up the new purposes of tempering ceramic material in furniture manufacturing industry, and can satisfy the requirement of furniture manufacturing technology again, manufactured out the furniture of new material.
The invention has the beneficial effects as follows:
1, helps protecting forest resources; what furniture used in a large number at present is woodwork, cut down a large amount of forests, thereby cause soil erosion; destroy environment; reduce the absorption of forest, the earth is heated up, the aggravation greenhouse effects carbon dioxide; and with Tao Daimu; can protect forest resources, the protection environment is protected human home.
2, help human health, human health is the eternal targets of people, and well-known, the processing and manufacturing of woodwork will be used industrial chemicals such as formaldehyde, dimethylbenzene.And existing medical research proof formaldehyde etc. are carcinogens, be detrimental to health, and tempering pottery furniture burn till through high temperature, and chemical property is stable, can not be detrimental to health.
3, no matter help recycling, be woodwork, or aluminium, steel, safety glass still are the use of plastics, and its service life is limited.And ceramic product is can 1,100 recycling, intact.Also can consume non-renewable natural resources though produce tempering pottery furniture, the characteristic that tempering pottery furniture can recycle is for a long time said and has protected the too fast consumption of natural resources from another angle.
