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:How much is the tableware wrapping machine?What's the price of the tableware wrapping machine?

Tableware packing machine? Should the packing of the tableware be contracted? Tak Cheung packing machinery, automatic heat shrinkable tableware packing machine can be considered

Q:The role of packaging equipment in packaging equipment

(4) it can reduce labor intensity and improve working conditionsThe 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.(5) labor protection for workersFor 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 packing cost and save the storage and transportation expensesFor loose products, such as cotton, tobacco, silk and hemp, the compression packing machine can reduce the volume and reduce the packing cost. 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.

Q:What does the mechanical equipment include?

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

Q:Whether you can press paper plastic molding after PET

Sure；Note cards must be coated with plastic oil;Can use blister sealing machine or high frequency plastic welding machine hot pressing;

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

Different conceptsCompression molding refers to hot forming: mainly for thermoplastic materials (sheet), the use of hot forming machine, Blister molding, I think it should also be considered as a branch of hot stamping, vacuum or high-pressure gas will be used to assist. Hot pressing sheet forming a relatively small depth, relatively simple structure, low precision products, such as packaging materials, plastic pallets, plates in the dishes and so on. There are also forming plate pressing molding (lamination)

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

If automated packaging, it depends on the factory situation, should not be from the user groups to start. If a small class of cosmetics do, then he will not say to buy a more than ten thousand or hundreds of thousands of automated equipment to pack ah. Automatic packing machine is certainly need a certain amount, a certain basis will be needed, or buy a mechanical automation a month the amount of packaging takes less than one hour, then buy this station automation machinery to do what? So, according to the automatic device, we can not start from the user groups, should be considered from the size of the factory.

Q:Working principle of packing machine

Then, by heating the sealing part of the bag bottom sealing, again is material, the material into the packaging machine, and then sealing, finally cut off, a complete package came out, this is the working principle of small vertical packaging machine.

Q:Ask a mechanical problem, the waste film recycling in the packaging machinery is a new film packaging, after cutting, then use the roller to recycle the waste film. Encounter a

Is it settled?. Not really! It is not recommended to use torque as parameter control here. This is a tricky amount of control. And easy to fluctuate, prone to misoperation

Q:What machine does the packing carton machine have?
