The dense degree of products obtained by using the device and the process is higher than products obtained by using a half-dry pressing method and a vibrating-vacuumizing method, and the strength, the durability and the appearance quality of the products obtained by using the device and the process are easier to be guaranteed.
Description
Technical field
The invention belongs to the plant equipment field, specifically relate to filter-pressing device and technology thereof in the waste material production of a kind of inorganic artificial marble.
Background technology
Artificial marble is claimed artificial stone, artificial stone, artificial-synthetic stone etc. again.Be that rock ballast or the glued again one-tenth of stone flour is whole, use as construction material.Be the bulk hexahedral shape like fruit product, be called the waste material of artificial marble.With the Dali Waste stone material cut, grind, processed such as polishing, can make decorative kind building board or section bar.
At present, the waste material of artificial marble is mainly organic artificial marble.System is a basic material with natural stone-powder or industrial chemicals, is adhesive with synthetic resin, through stir, mat formation, vibrate, vacuumize, solidify, operation such as the demoulding processes.Be characterized in: compact structure, rich color, higher, ornamental stronger with this sheet material photochromism of making.But exist case hardness low, a little less than the anti-delineation performance, shortcomings such as poor heat resistance, resistance to ag(e)ing difference are after long-term the use; Sheet material deforms easily, fades, and sheet material can burn or coking when meeting fire, when room temperature is higher; Can produce pernicious gas, cause room air pollution, the harm health of human body.
Artificial marble with gluings such as cement, gypsum, magnesias is called inorganic artificial marble.Generally, the waste material of inorganic artificial marble system is a basic material with natural stone-powder, industrial residue or Inorganic Chemicals etc., is adhesive with the special cement, forms through stirring, cast, vibration, maintenance.Its advantage is not contain harmful volatile organic matter, and heat-resisting, fire prevention and resistance to ag(e)ing are stronger, but owing to innerly contain more hole, cause the intensity of stone material lower, glossiness is lower, pollution resistance is relatively poor, thereby can only be used as low-grade decorative building material.
Produce at aspects such as outward appearance, physical and mechanical properties, chemical composition and chemical properties, all, must adopt the inorganic artificial marble approach near the waste material of the artificial marble of natural marble.And to produce the waste material of high-grade inorganic artificial marble, and key is that the structure that must guarantee stone material reaches farthest closely knit, too much hole must not contained in inside.Cross mushy method in the elimination artificial marble at present and have two kinds: the one, chemical method promptly adopts some surfactants to eliminate the bubble of sneaking in whipping process, or adopts the raw material that can form colloidal substance to be filled in the hole.Yet, facts have proved, adopt chemical means can't eliminate the pore in the inorganic artificial marble fully merely at all, more be difficult to reach the density and the packing of similar natural marble.Eliminating and crossing mushy second method in the artificial marble is the physics method, generally at present adopts two kinds of measures: the one, adopt the half-dried platen press of the less ratio of mud (mass ratio of water and dry material).But find that this method still can't all get rid of the inner pore of the waste material of inorganic artificial marble, and be prone to produce the stronger laminar crack of marble structural deterioration property; The 2nd, adopt the vibration+vacuumizing method of the ratio of mud greatly.But this method equipment manufacturing cost is very high, and energy consumption is very big.
Summary of the invention
