Q:Donkey hide gelatin cake made of sticky, forming very well, that is, vacuum packaging, after a little sticky in the vacuum bag, what's going on?

For custom vacuum bags, I would recommend a manufacturer who has customized experience in vacuum bags because it reduces your time cost and offers a lot of advice on packaging design and customization.

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:Packaging machine knife cut out of the mouth is uneven, always inclined, so adjust, now tune not come back, or is unable to cut off, or die!

This situation is best to find after sale processing, you have difficulty adjusting normal

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)
