Abstract
The invention relates to a filter press filter plate production process. The process consists of: firstly adding high polymer plastic resin and commonly used additive, antioxidant, crosslinking agent and the like into a vacuum reaction kettle together, conducting heating melting under a vacuum state, then using a melt pump to pump the melt into a mold placed in an oven, and performing natural cooling to room temperature, disassembling the mold and carrying out necessary finishing. The manufacturing process involved in the invention is simple and is low in cost, and the use performance is reliable. Because of one-time casting molding, intermediate links are reduced, and the product cleanliness and surface quality are ensured. The finished product has no need of machining, and the raw materials are saved. The production process provided by the invention guarantees the product flatness, and the product does not deform permanently. The filter press filter plate manufactured by the process provided by the invention has the advantages of light weight, high strength, good wear resistance, small friction coefficient and the like.
Description
Technical field
The present invention relates to a kind of filter press filter board production technology, belong to filter press filter board and manufacture field.
Background technology
At present; the filter press of solid-liquid two-phase laminated flow equipment is used in departments such as light industry, chemical industry and environmental protection; its strainer plate material kind is more; as cast iron, cast steel, cast aluminium, fiberglass, rubber, polypropylene and engineering plastics etc.; in these materials, some intensity is better; but weight is large, perishable, filtrate is had to the possibility of pollution.And some material weight are light, resistance to corrosion is better, and price is high.Some intensity is lower, and the easy generation permanent deformation had, affects service life.And on strainer plate material and structure, all fail to solve the problem increasing filter pressure raising solid-liquid separation effect.The most frequently used is plastic filter plate in the market, is subject to extensive use because of features such as its quality is light, corrosion-resistant, long service life.Traditional filter plate pressing process is clamp-oned in insulation charging basket after adopting spiro rod plasticizing, by manually proceeding to mold pressing again after mould after weighing, this technique greatest drawback is: one is that singe screw plasticization temperature is higher, and material property loss is large; Two is that charging basket heat insulation effect is undesirable, non-uniform temperature; Three is that the charging basket moving process time is long, needs a few minutes; Four is that filter plate cold shut, pore are many; Five is that technique places one's entire reliance upon manual operation, and cleannes are poor; Six is that filter plate intensity, quality are not moved calmly; Seven is that automaticity is low, and the production cycle is long, particularly large gauge filter plate.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of filter press filter board production method of good performance.
The technical scheme realizing above-mentioned purpose is: join in vacuum reaction still by high molecule plastic resin together with conventional auxiliary agent, antioxidant, crosslinking agent etc., heating and melting under vacuum conditions.Then by Melt Pump, melt is driven into the mould be placed in baking oven, makes it naturally cool to room temperature.Take mould apart, carry out necessary finishing.
Further, the heating-up temperature of the above vacuum reaction still is 165-220 DEG C.
Further, the heating-up temperature of the above baking oven inner mold is higher than the heating-up temperature of reactor 10 DEG C.
Further, the above high molecule plastic resin is polyethylene or polyacrylic one.
The present invention is compared with background technology, and process for machining and manufacturing is easy, and cost is low, and serviceability is reliable.Because of its one-time cast-forming, cut down the number of intermediate links, ensure product cleannes and surface quality.Finished product does not need machining, has saved raw material.Production technology of the present invention ensure that the flatness of product, is out of shape never.With the filter press filter board that the present invention makes, there is the advantages such as lightweight, intensity is high, wearability good, coefficient of friction is little.This filter plate can use on the filter presses such as ceramic industry, chemical industry, light industry, food industry.
Detailed description of the invention
A kind of plastic filter plate production technology, first joins in vacuum reaction still by high molecule plastic resin, heating and melting under vacuum conditions together with conventional auxiliary agent, antioxidant, crosslinking agent etc.Then by Melt Pump, melt is driven into the mould be placed in baking oven, makes it naturally cool to room temperature.Take mould apart, carry out necessary finishing.
Further, the heating-up temperature of the above vacuum reaction still is 165-220 DEG C.
Further, the heating-up temperature of the above baking oven inner mold is higher than the heating-up temperature of reactor 10 DEG C.
Further, the above high molecule plastic resin is polyethylene or polyacrylic one.
It should be noted that: although above-mentioned embodiment is to detailed description of contrasting to the present invention; but these explanations are only limitted to illustrate the present embodiment; instead of limitation of the present invention, any innovation and creation do not exceeded in connotation of the present invention, all fall within protection scope of the present invention.
