Description
Technical field
The present invention relates to a kind of processing technology of industrial synthetic stone, relate in particular to a kind of processing technology that is used to make the thin plate industrial synthetic stone.
Background technology
Lithotome is as the pith of construction material, because its color variation, exploitation is extensive use of by the people easily since ancient times always.But along with the excessive increase of its yield, exploit reasons such as utilization rate is low, the exploitation of lithotome progressively is restricted, and particularly some European countries has forbidden the exploitation of lithotome.And the product in each mineral products district, its pattern, kind all is only one, has more increased its difficulty of using.People are seeking its substitute always.
Eighties of last century sixties, du pont company for the substitute of production natural stone countertops plate, and has been invented entity plane materiel, is commonly called as resin plate, it is characterized in that it is formed by resin cast fully.At the invention initial stage,, produce easily, and extensively promoted just because its pattern is many.Up to today, entity plane materiel remains one of main selection of deck plate.Its extension product is also a lot, is mostly to add some toners therein, and calcium powder, fillers such as aluminium powder increase pattern, reduce cost.Its production technology is generally hybrid resin, additive and various auxiliary agent, and cast molding is solidified then.But the defective of this kind resin plate is also brought inconvenience to people, because its primary raw material is a resin, its hardness is low, fade easily, and easy deformation, ageing resistance is low.Especially in the place that is often contacted by people, as bank counter, the household kitchen table top, the problems referred to above will appear in places such as hotel's table top in the short period of time, often polishing renovation.Patent about this kind invention is varied.
Consider these the jejune characteristics and the what use is made of lithotome waste material of resin plate,, invented artificial synthetic stone by Italian PTI company at the end of the sixties.It is characterized in that utilizing the resin natural stone particle that bonds.Because added a large amount of lithotomes, its hardness has improved, and pattern is more various, and it is in appearance more near natural stone, has promptly fully consumed a large amount of lithotome particles, meets the characteristics that people like lithotome again.The initial stage technology of this kind product is simple, only is to use resin-bonded particle, has produced a lot of inventions, as ZL 200410086755.4 " synthetic color slate and manufacture method thereof "; The manufacturing prescription and the production technology of the colored artificial stone of CN03109409.0.These inventions just simply utilize the mixed with resin building stones, do not solve the various defectives of bringing to product because use resin in a large number, and are not enough as hardness, the water imbibition height, yielding, problem such as easily aging, just low than the production cost of resin plate, seem near lithotome.
Artificial synthetic stone develops into today, and its most up-to-date techniques are the artificial synthetic hilllock stone that is commonly called as today.The all processes of its production technology all is to finish under the situation of vacuum: hybrid resin and lithotome aggregate and additive, cloth is expected the feed bin the inside of a 2400cm*1200cm*90cm then, the extruding of before and after this feed bin being carried out up and down, vibrating, be shaped to the hilllock Waste stone material until it, treat to carry out dicing, sanding and polishing after it solidifies.China introduces in the last world end of the nineties, has copied this equipment, and promotes rapidly, and its product has been installed in the inside, most market so far.This technology is elaborated at invention 200410051312.1 " production technology of artificial stone and devices ".The defective of this product still exists.At first we look at his production technology, at first will be pressed into the waste material of bulk, the famine material are cut again.This technology has limited the hardness of the lithotome aggregate in the waste material because of the limitation of current cutting technique, can only use hardness lithotome on the low side in other words, otherwise just can not cut.Generally speaking, people to select hardness mostly for use be that Mohs' hardness is that about 3,4 marble and hardness are 5 granite for Mohs intensity.Because can only select these stone materials for use, the hardness of its product and intensity are not very high, the scope of application of having limited to its product, as, can not use as the household kitchen countertop plate, as be installed in the inside, market and wait the extensive place of walking about that contacts of quilt, cut will soon appear, pollute infiltration, problems such as variable color.Produced a large amount of losses in its cutting process simultaneously.Increased the expense of cost.
Secondly, this equipment be adopt this cube feed bin carried out before and after up and down extrusion modling, in process of production, its active force can not reach enough greatly, so must add the abundant resin lithotome particle that bonds.Because its pressure is not enough, the density of product is good inadequately, because its resin content is many, characteristics such as the hardness of its product still can not reach requirement.Increased cost again.
And, because it is enough big that the active force that press produced in this equipment can not reach, if use many vibrating motors to act on the oscillating plate, just must solve the same frequency of these motors, the technical barrier of synchronous effect, therefore just can not increase the size of feed bin, like this just limit the specification of this kind product.
Based on above-mentioned defective, the equipment design engineers of various countries are in research and development, because can not the high stone material aggregate of cutting hardness, its solution is the technology of a kind of direct processing sheet of exploitation, after this technology generally requires material completed, system is vibrated by large-scale vibrating, the press of this kind equipment will have enough big pressure and oscillating force, can press aggregate more closely knitly, like this just can reduce the use amount of resin, and the density of raising product, the anti-permeability and the corrosion resistance of increase product.The active force that how to improve this press is the key of this invention, and existing press is the vibrating motor of a large-scale vibrating motor being installed above the oscillating plate or two or more being installed at.If increase power just must invent a kind of more large-scale vibrating motor, but prior art can not address this problem, and the increase power that this large-scale vibrating motor can not be unlimited.Perhaps be increased in the quantity of this vibrating motor above oscillating plate, but must solve the same frequency of these vibrating motors, synchronous problem.This also is technical difficult point, and vibrating motor of every increase simultaneously will be in the face of together frequently, synchronous problem.And multiple motor acts on the oscillating plate simultaneously, and its work stable low can not guarantee completely with frequently, synchronously.Therefore, the thin plate of this explained hereafter is subjected to the restriction on the size equally, also can't produce large-sized thin plate sheet material.
