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

Q:Which friend is an expert in mechanical equipment or a better understanding of sealing machines? Tell me how to identify the equipment

If these are good, and then talk about the price, always a penny goods, this side, quick packaging machine is not bad,

Q:What does the mechanical equipment include?

Hydraulic lifting track machineHydraulic tamping machine, rail sawing machine, rail machine

Q:What does that mean when the composite material is pressed and molded? What are pressing forming? What are the characteristics of press molding equipment? Its development

Molding: mainly used for thermosetting resins. There is a special molding machine. Molding pressure is much greater than the above. The mold structure is also more complex.

Q:The role of food packaging machinery

3) to achieve manual packaging can not achieve the operation, some packaging operations, such as vacuum packaging, inflatable packaging, body packing, isobaric filling, etc., are manual packaging can not be achieved, can only be achieved by mechanical packaging.(4) can reduce labor intensity, improve the working conditions of the labor intensity of manual packaging, such as volume, weight heavy manual packaging products, both the consumption of physical strength, and safety; and for small and light products, due to high frequency, easy to make the action monotonous, worker occupation disease. Carton folding machine(5) in favor of labor protection for some serious impact on health products, such as serious dust, toxic products, irritating, radioactive products, manual packaging is a health hazard, and packaging machinery can be avoided, and can effectively protect the environment from being polluted.(6) it can reduce the cost of packing and save the storage and transportation expenses. It can reduce the volume and reduce the packing cost by compressing and packing the loose products, such as cotton, tobacco leaf, silk and hemp. At the same time, due to the reduction of large volume, in order to save storage capacity, reduce storage costs, is conducive to the transport.(7) ensure product health of certain products, such as food and drug packaging, according to the health law is not allowed to use manual packaging, because it will pollute the products and packaging machinery to avoid direct contact with the staff of food and medicine, to ensure the quality of health.

Q:Is there anyone who knows what groups of users of packaging machinery are in general?

This is really not sure, it can be said that any group, as long as the packaging products are required to use packaging machinery. Most of the products are now in need of packing. So it can be said that any group.

Q:Bread packing machine Product features
