Q:What are the main functions of packaging machinery?

The main means of packaging is the use of packaging machinery. With the development of the times and the progress of technology, packaging machinery is playing a more and more important role in the field of packaging

Q:What are the main plastic forming processes?

Plastic processing is a complex process, generally divided into the following processing methods:In order to improve the quality of the product and improve the molding efficiency, the pre pressing is used to press the powder or fibrous molding material into a certain shape in advance.Preheating, in order to improve the processing performance and shorten the molding cycle of molding plastics, the molding plastics are heated prior to molding.Molding in the mold to add the required amount of plastic, closed mold and exhaust, at the mold temperature and pressure to maintain a period of time, and then release mold cleaning operations

Q:What are the main functions of packaging machinery and equipment?

Sealing and other major operations, and related processes before and after,

Q:How does the pulp solidify? What additives do you need? Curing agents? Or what do you need as binders?

(1) urea formaldehyde moulding powder;The resin powder of urea formaldehyde resin, commonly known as electric jade powder, is produced by wet process, such as tree ester, curing agent, filler, colorant, lubricant, stabilizer, plasticizer and so on1 Components(1) resin used for urea formaldehyde resin molding powder by condensation reaction degree is relatively shallow, the resin with low viscosity, easy dipping filler, and can ensure the long production cycle and drying after proper fluidity, condensate in the industrial use of urea and formaldehyde at low temperature (a mixture of dimethylol urea, urea and formaldehyde) are usually used. The ratio of 1:1.5 (molar ratio), the PH=8 (and temperature) 30 - 35 of all dissolved, adding urea oxalate was 0.3% - 0.33% and 0.88% - 0.54% of the oxalic acid, then the occurrence of exothermic reaction, temperature rise, temperature in 55 - 60 degrees, and strictly control the PH=5.5 - 6.5, 60 - 75min by urea formaldehyde resin is required. Because the condensation degree is low, in fact just over addition reaction, condensation reaction is mainly in the curing process.(2) the curing agent used in curing agent and pressing powder requires latent, usually oxalic acid, phthalic acid, two formic acid, benzoic acid, chloroacetic acid, etc.(3) packing material is the most commonly used pulp, followed by wood powder or inorganic fillers (glass fiber, asbestos, mica etc.). The pulp is wood as raw material, with sodium bisulfite, non soluble cellulose impurities to the wood, and then byThat is the pure cellulose bleaching. The amount of filler material for the total amount of 25%-32%, the amount is too small, the pressure of plastic powder fluidity big, product strength is low; on the contrary, the amount of excessive pressure, plastic powder fluidity decreases, the product surface is not smooth, water
