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
What is the general packing cost of beer beverage packaging?
Beer beverage hot shrink packaging generally use PE heat shrinkable film, packaging temperature is usually in accordance with the film material and thickness to set,
Where is secondhand corrugated paper packaging machinery available?
Start a small yellow cardboard box factory, they have the best business, began the purchase of machinery, plant hire.In an unfamiliar field, we should listen to the opinions of experienced people.Carton is a supporting product of consumer products, so to speak, as long as people have consumption, enterprises and products, there will be no lack of product packaging.
What is a packaging machine?
Well, before and after the associated processes, such as cleaning, stacking and disassembly. In addition, the package also includes the measurement or in the processes of stamp packages. Mechanical packaging products can improve productivity, reduce labor intensity
Bread packing machine Product features
Product features1. double frequency control, bag length is cut, no need to adjust the empty walk, one step in place, save time and save the film.2. man-machine interface, parameter setting is convenient and quick.3. fault diagnosis function, clear failure display.
Energy saving reform of packaging machine
A) the main control circuit is composed of man-machine interface (text display), frequency converter and programmable logic controller (PLC), which constitute the control core;B) the temperature control circuit is composed of an intelligent temperature control meter, a solid state relay and a thermocouple element. The temperature control is accurate, the display is intuitive, and the setting is convenient;C) multi point tracking and detection by photoelectric switches and electromagnetic proximity sensors; 2) fully automatic pillow type working principle:With the improvement of automation, the operation, maintenance and routine maintenance of the packing machine are more convenient and simple, and the professional skill requirements of the operators are reduced. The quality of the product packaging is directly related to the temperature system, the speed accuracy of the main engine and the stability of the tracking system.
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
It's a good mechanical design problem! In principle, yes, for example, to achieve the rated torque of the motor. He'll stop by himself! What isn't that great torque? You can zoom in on the load torque
