Abstract
The invention discloses a compacting method for a 3D furred ceiling, which belongs to the field of sheet materials. A 315-ton press machine is employed for mold pressing; pressure-velocity is calculated in segments; gas in a material is completely evacuated during mold pressing; and the obtained3D furred ceiling has high stability and no fracture and crack and completely presents a 3D form, so product quality is guaranteed.
Description
Technical field
The invention belongs to sheet material field, be specifically related to a kind of drawing method of 3D furred ceiling.
Background technology
The material adopted in China's furred ceiling industry is most of by plasterboard, PVC material or metallic material of aluminum are made, manufacture craft is simple, manufacture craft must produce certain impact to the performance of product simply, first, furred ceiling is the earliest from plasterboard, although plaster tablet suspended ceiling is simply shaping, but really but there is many shortcomings, along with modern process has many families and enterprise to also have public place, some used special furred ceilings, plaster tablet suspended ceiling cannot realize really, so, the furred ceiling of antibacterial fungistatic is used in national various big hospital, food processing, medicine, the workshop of the industries such as medical treatment, laboratory, operating room etc., and plaster tablet suspended ceiling is easy to the moisture absorption, go mouldy, distortion, and service life is very short, within about 3 years, must change once, cause industry-by-industry and house decoration trouble, plaster tablet suspended ceiling also has a fatal shortcoming to be that quality is large, intensity is low, its intensity source is mainly by increasing the thickness acquisition of gypsum furred ceiling, so, gypsum furred ceiling intensity is higher, thickness is thicker, thus quality is heavier.
Second developing stage of furred ceiling is PVC material furred ceiling, what the furred ceiling of PVC plastic was taked is, and what to propose that the structure of handicraft product adopts is hollow corrugated structure, its shortcoming can discharge toxic gas in the forming process of technique, because the chemical analysis of PVC plastic mainly polyoxyethylene, and the releasing of oxygen element is very large to human health damage, be exactly the ageing-resistant very poor of PVC plastic in addition, although his acylous action is fine, but uvioresistant is very poor, namely use less than and just there will be in year and become fragile, turn yellow, reduce the problems such as intensity, PVC plastic is also had to be thermoplastic, when it runs into temperature be, can softening transform.
Present stage, the market of furred ceiling was all the furred ceiling market of aluminum mostly, the furred ceiling technique of aluminum is also simple, and mechanical stamping, then in technology such as printing, overlay film, hot transfer printings, design producing on the furred ceiling of aluminum, but it is also have a lot of shortcoming: such as aluminum furred ceiling is in order to reduce weight, improve the competition in market, take the method subtracting wall thickness, the thickness of general aluminum furred ceiling only has 0.1-0.3mm thick, very thin, and the intensity that result also in it like this declines.The composition of aluminum furred ceiling is metal, and the shortcoming of metal is easily oxidation and corrosion, adds so thin; just more easily produce Xian's point, rotten problem, so; the furred ceiling of a large-scale natatorium; because its environment is moister and have acidity, the place of natatorium is public place, so often can carry out sterilization in water; cause sour gas in rising; aluminum suspended ceiling pinch plate forms the corrosion to aluminum-pinch, so cannot use at all; The thickness of aluminum furred ceiling is too thin, cannot the large suspended ceiling pinch plate of manufactured size, and great majority are 30*30mm, in public or the large-scale occasion stage adopt the buckle of 60*60mm and 60*120mm, and aluminum plate cannot realize.In the life of 4. present stage people, the plane effect of two dimension is slowly faded away by people, and the thing followed is the hyperspace of 3D, and aluminum plate wants the buckle that drawing and forming becomes 3D, and its cost can be very high, and general people cannot accept, and quality also can be very heavy.
Now these three kinds of suspended ceiling pinch plates are commercially all exist simultaneously, and the suspended ceiling pinch plate that the DMC material that we select (DMC is that the abbreviation " Dough moulding Compounds " of three English words means: the soft bulk heat curing-type moulding material that unsaturated polyester (UP) short glass fiber strengthens) makes can replace three kinds of above furred ceilings simultaneously, in this new material successful Application at automobile, aircraft, the interior trim of high ferro, we and very warm title it be " aeronautical material ", its advantage is: intensity is high, because there is fiberglass reinforcement corrosion-resistant, at strong acid, in the fester body of highly basic it that Not a hair of one's head shall be touched is ageing-resistant, uvioresistant, long service life, its service life can be fire-retardant for 50 years, fire prevention can the various 3D effect of one-shot forming antibacterial, antibacterial, damp proof insulation, heat insulation installation and facilitate heat distortion temperature high, can reach 240 ° aseptic, environmental protection.
And the key technology of DMC material is compressing, this is a difficult point, suppresses unsuccessful meeting and causes there is bubble in finished product, and finished product breaks because of compacting, suppresses distortion, the series of problems such as finished product thickness differs, and texture is poor, uneven color.
Summary of the invention
The object of the invention is to the drawing method of a kind of 3D furred ceiling provided for the deficiencies in the prior art, to solve 3D visual effect, finished product texture, color is even, bubble-free problem in finished product.
The present invention is achieved by the following technical solutions:
Get DMC material according to precalculated compressing size to weigh, pinch into after weighing
Bulk, puts into the water that zinc stearate and calcium stearate are housed and soaks 10 minutes.
The bulk DMC material taken out after soaking is put on the 3D mould of molding press, and temperature during pressing mold is 160 DEG C-170 DEG C.
Adopt 315 tons of forcing press pressing molds during pressing mold, pressure is 25Mpa, and pressure x velocity is set to fast downlink (3mm/s) → middling speed downslide (8-10mm/s) → slow pressurization (1-3mm/s) → pressurize 2min → quick return (20mm/s).
Die sinking takes out finished product smooth for finished product edge treated packing and binding.
The present invention adopts 315 tons of forcing press pressing molds, and pressure x velocity segmentation calculates, and completely by the air scavenge in material in pressing mold process, and stability is high, and finished product, without fracture or crackle, presents 3D form completely, ensure that product quality.
Detailed description of the invention
Get DMC material according to precalculated compressing size to weigh, pinch into after weighing
Bulk, puts into the water that zinc stearate and calcium stearate are housed and soaks 10 minutes.
The bulk DMC material taken out after soaking is put on the 3D mould of molding press, and temperature during pressing mold is 160 DEG C-170 DEG C.
Adopt 315 tons of forcing press pressing molds during pressing mold, pressure is 25Mpa, and pressure x velocity is set to fast downlink (3mm/s) → middling speed downslide (8-10mm/s) → slow pressurization (1-3mm/s) → pressurize 2min → quick return (20mm/s).
