Q: Blue belt principle is what?
Also known as orchid. The black metal surface by the "blue bluing" after the formation of the oxide film, the outer layer is mainly magnetite, the inner layer is feo.
Q: Polypropylene packing belt edge why will be scared
Polypropylene is a thermoplastic resin made by the polymerization of propylene. According to the location of the methyl group into isotactic polypropylene (isotactic, polyprolene), random polypropylene (atactic polypropylene) and syndiotactic polypropylene (syndiotactic, polypropylene) three kinds.
Q: Identification of the quality of the packing belt
PET plastic steel belt identification: the most important standard (not crisp, is to use clamps will be packaged with the middle of the pack, just sampling clamping, cracking, rupture is the most poor packing belt, lines should have been clear, color should be transparent, with small font size 7 in the package down to see this just clear, packing belt very good.
Q: What is the reason that the packing belt of the packer is not glued?
Could you change the original packing tape, packing tape thickness is relatively thick, and now the thin, semi automatic strapping machine head can not be fully in place. Solution: adjust the head position again
Q: What should I pay attention to, such as whether it should be printed on the inner surface or the outer surface? Also, can the pure transparent packing belt be printed? What are the special requirements for ink? Will increase the cost, etc., we sincerely hope that your heroes.
First of all, the extruder temperature control is generally between 250 and 280 degrees centigrade. The next is cooling, strip out the head temperature is very high, to immediately enter the water cooling, because of isotactic polypropylene in acute cold conditions easily generated has crystal structure, molecular structure of paracrystals was loose. In this way, the strap is easy to stretch and obtain high quality products. Then, the tensile and tensile purposes are to increase the longitudinal strength of the strap and reduce the elongation. Tension must be carried out in boiling water, usually by one stretch. Finally, the embossing, stretching after the packaging belt, after two patterns of pressure roller, it will be pressed on the pattern, its role is to increase friction in use, do not slip, from the appearance of looking handsome.
Q: What are the classification of the packing belt?
That's a lot of sorting. According to what parameter you want to divide.Generally have PP packaging belt, PET packaging belt.Machine packing belt and hand packing beltNew material packing belt and feed back packing belt.Also transparent and opaque. Having or having no color. Wait
Q: What kind of joints are used in the packing belt?
Iron buckle packing.The one-way tensioner ratchet, the packing tape tensioning, then pack joints placed a hasp, hasp and clamps make wrap two layer packing belt, and the tooth shaped hasp side teeth bump, bite strap does not cause the loose. Usually made of galvanized sheet iron buckle, the operation to choose to adapt according to the specifications of the metal packing belt type.
Q: Is the profit margin of the packing belt line large?
Profit in general, buy materials to 6000 far, the finished product in the market price more than 6000 yuan, remove the rent, electricity, wages were flat! I'm switching now!!!! At that time I bought a new branch of machinery, worked for seven months, now want to sell, but I do not know where the old equipment received
Q: Do you need a packing belt for the airport consignment bag?
If your bags are intact, no packing straps are required. They are usually packed in flimsy cartons or bags
Q: Do you have your bags ready before boarding?
To check the plane's luggage, if the bag, rod boxes do not pack themselves to zip, if it is the case, to do the packaging, fragile to check in to inform, if they do not have to pack, pack at the airport, need to charge 20 yuan fee, if the home has a package their tools can be packaged to trip!
