Shandong import adhesives with shandong import adhesives how in 2, according to the pur polyurethane hot melt adhesive machine and additional peripheral devices required load, check the use of the power cord and insulation protection is in line with the provisions, load of the wire must be higher than the rated power of the pur hot melt glue machine more than thirty percent. 2, bags of composite technology: EVA after composite process with normal cloth, cut again stamping shape, finish making bags; Shandong import adhesive melting point - how to use 70℃。 And the storage life of hot-melt adhesive for 2 years, store covers an area of small, no special storage requirements; And tape storage is valid only for half a year, also requires a certain storage conditions, otherwise easy to spoil. 3, box making composite process: cloth and hard EVA glue, respectively, after the glue dry storage respectively. When necessary, the cloth and EVA each cut into small pieces. 180 ℃ high temperature baking EVA about 3 minutes, remove the EVA quickly the cloth evenly on the EVA, immediately press finalize the design, complete the box; If change cloth, glue, EVA and other materials and coating failure downtime, please put the glue spreader idling in circles, wait for the rubber roller surface swear glue; How to use a, shandong import adhesives heating using solvent cleaning with viscose element, never use the fireworks or no temperature control of heating equipment cleaning, general pur moisture reactive polyurethane hot melt adhesive machine can't operate 280 degrees when cleaning and maintenance. Hot melt adhesive coating machine working principle is very simple, even if we don't have the industry expertise, as long as a bit of physical and chemical aspects of knowledge, it's easier to grasp, actually said simple point is the heat bilges cold shrink. 4, handbags composite process: soft material according to the normal composite composite process. Is so much advantage is hot melt machine since their introduction, favored by the market constantly. 5, and manual or machine double-sided glue, glue dry fast, winding or stacked base material, respectively, to joint, roller heated to about 120 ℃, base material of neat, roller compaction, the complete composite. Base material is cool after see effect. If change cloth, glue, EVA and other materials and coating failure downtime, please put the glue spreader idling around, when thou hast rubber roller surface glue again. How to use the note editor 1 shandong import adhesives, must pay attention to when using product evenly coated in the glued surfaces, glued surfaces must be dry, clean, without oily coating construction can proceed, it will affect the normal bonding; Shandong import adhesives used to how to use the work to maintain good health packaging and storage is suitable for BOPP, PET aluminum plating film and paper combined with the technical indicators viscosity 15 ~ 40 s and adjust the indicators according to the laminating process, when using, do not add water or other solvents 20 kg, 50 kg buckets used in the product use this kind of pressure sensitive adhesive is natural rubber elastomer early, later gradually extended to all kinds of synthetic rubber, thermoplastic elastomer. 1, can under the professional instrument for testing analyzing the composition of hot melt adhesive, so that we can get the accurate data. Viscosity of 5. 34mPa·s( 25℃) 。 2, because of the glue in the glue tank, and air contact area is large, will cause the evaporation of solvent in the glue, which affect the glue viscosity changes, so demands in use process, depending on the situation to join a small amount of thinner, adjust appropriately, the viscosity will be transferred to the coating viscosity; While using the principle of not very complicated, but in the process, bring convenience to our some production life work really huge, a feature is to save the drying equipment, this not only saves redundant procedures, eliminating the dryer and so on equipment cost, it is kill two birds with one stone. How to use the second, shandong import adhesive stickers with poor resistance to low temperature, cold climate in the north, does easy to glue; Hot melt adhesive, good low temperature resistance, resistant to - 40 ℃ low temperature.
