Q:Food, equipment, tools, containers, packaging materials, etc. shall comply with food safety standards or requirements

5009.101 determination of antimony in polyester resins and their moulding products for food containers and packaging materialsGB 13113 hygienic standard for polyethylene terephthalate moulding articles for food containers and packaging materials

Q:How is the production and characteristics of ceramic wall tiles different from the size and performance of molding?

What is the size of the parison forming pressure and the performance of the ceramic wall and floor tile products?Ceramic wall and floor tiles are usually formed by pressing. Domestic made for 30 tons, imported equipment has tons of suppression, 200 tons and 500 tons. In order to smooth accurate size, excellent products, must pay attention to the effect of powder properties and compression of products. That is to say, the quality of the floor tiles, billets, methods of preparation, and the quality of products and production scale and way of pressing machinery. As for pressing pressure, as the molding pressure decreases, the sintering shrinkage becomes smaller and the water absorption rate becomes smaller, the durability of the product should be improved. It should be noted that the pressure should not be too high. Excessive pressure, stress, and density increase will cause unnecessary energy consumption, and cause compressed air to expand after pressure is canceled and cause excessive spalling.

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?

Now the standard of living has improved, basically the vacuum bag. This will improve the product's shelf life, preservation time is longer, more conducive to product sales.

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

Urea formaldehyde resinUre-aformaldehyde resinsUrea formaldehyde polymer. Also called urea formaldehyde resin. The cross-linking English abbreviation UF. molding, the product is insoluble and infusible thermosetting resin, urea formaldehyde resin cured phenolic resin than the color of light, translucent resistance, weak acid and weak alkali, good insulation properties, excellent wear resistance, low price but, in case of strong acid and strong alkali decomposition, weather resistance is poor. The name Beetle. urea and 37% formaldehyde aqueous solution can be obtained by the polycondensation of linear urea formaldehyde oligomer in catalytic acid or alkali industry, with alkali as catalyst, reaction temperature of about 95, the molar ratio of formaldehyde to urea as 1.2.0, to ensure that the resin curing reaction. The first step to generate and dimethylol urea, then hydroxymethyl amino and soluble resin by further condensation, if by acid catalysis, easy to cause the product to be stored to gel. In neutral condition. The linear UF resin for ammonium chloride Curing agent can be cured at room temperature. The molding powder at 130 to 160 DEG C heat curing accelerators such as zinc sulfate, trimethyl phosphate, two oxalic acid ethyl ester can accelerate the curing process. The urea formaldehyde resin is mainly used in the manufacture of molded plastic manufacturing, daily life products and appliance parts, also can be used as adhesive, paper and fabric sheet the pulp, plywood, decorative board and so on. Because of its light color and easy coloring, products often colorful and magnificent.

Q:Where is secondhand corrugated paper packaging machinery available?

Carton factory and general production enterprise is different,General business is to face direct consumers, the need for their own sales network, sales staff, sales means......And carton factory as long as accurate manufacturers, show their means, get business.Maybe you walked into a food factory, an electrical factory, a furniture factory, a toy factory...... Can be your client.With business, but also to choose their own plant.Cartons are flammable and afraid of water. This is the disadvantage of cartons. If handled properly, there will be no problem.Site is best to avoid low-lying and rainy lots of water, the cardboard should not be piled directly on the ground, the bracket is a good choice.No smoking in the factory area, no open fire, and good fire fighting equipment, so as to ensure the safety of production.The size of the initial plant is best to be 500 square meters, or larger, smaller.

Q:Three dimensional packaging machine, transparent film packaging machine, transparent film three-dimensional packaging machine industry standards

Q: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.

Q:Vacuum packing machine for cooked food: can whole chicken, whole goose and whole duck be packed?

Sometimes, this wine packaging PigHead, with different types of vacuum packaging machine

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: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.
