Melamine, as an organic chemical intermediate product, has a wide range of USES. As the raw material for the production of melamine formaldehyde resin (MF), melamine is the most important use.In addition, melamine can also be used as water reducer, flame retardant, formaldehyde cleaner.Melamine formaldehyde resin hardness than urea formaldehyde resin, not flammable, water resistance, heat resistance, aging resistance, arc resistance, chemical corrosion resistance, good insulation performance, gloss and mechanical strength, widely used in wood, plastic, paint, paper, textile, leather, electrical, pharmaceutical and other industries.
Melamine powder is to melamine formaldehyde resin as raw material, with cellulose as the base material, add pigment and other additives.Melamine powder is the raw material of imitation porcelain tableware. The processing procedure of melamine powder into tableware is as follows:
1. Preheating procedure: weigh the raw materials according to the tableware produced by the raw material box, and put them into the high frequency uniform preheating, and let the powder raw materials be heated into blocks.
2.Plain surface program: pour the preheated agglomerated raw materials into the mold, start the mechanical plain surface program, and then pass high temperature and high pressure, curing and forming.
3.Decal procedure: cut the paper according to the shape of the flower and stick it on the tableware with plain surface according to the requirement. The paper should be pasted upright and the decal orientation is moderate to make people look beautiful and generous. Start the mechanical printing procedure by pasting the flower.Four.Add gold procedure: after the product has stuck the flower, evenly sprinkle on the surface of the product light powder, light powder can not be sprinkled less, otherwise affect the color and luster of the product, of course, also can not be sprinkled more.Then start the machine, after mechanical high temperature and high pressure, curing, the surface of the product has the bright lustre of porcelain.
Five.Polishing process: after the product is produced, it needs to be polished and polished, because the product has rough edges, which is not conducive to people's life and easy to cause damage to their hands and mouths.Therefore, polishing and polishing are essential. By polishing and polishing, the rough edges of the products can be removed to make the products look more beautiful and the edges more smooth.
Six.Inspection and packaging procedures: polishing operations, the entry of the inspection link, strict quality inspection, should have a preliminary inspection and reinspection, pick out unqualified products, and then into the warehouse packaging.
