Huizhou whole series of food-grade plastic equipment huizhou whole series of food-grade plastic equipment 4, clean up the pur hot melt adhesive machine heating platen, workers must wear special high temperature resistant protective clothing, with high temperature resistant gloves, do not make the skin contact with hot melt glue barrel, molten pur hot melt adhesive and hot plate and high temperature parts, to avoid. 5. Water-based glue to use plastic containers, do not use metal containers, otherwise it will affect the glue of resistance to yellowing coefficient. Huizhou whole series of food-grade plastic equipment as a result, over the past 20 years, this kind of pressure sensitive adhesive is developing very rapidly, and have replaced the dominance of natural rubber pressure-sensitive adhesive. Epoxy resin epoxy resin with low shrinkage rate, resistance to mildew, properties, such as stable point. 6. Water-based glue because volatilizes slower, must add 5% of waterborne curing agent, and mixing 5 - 8 minutes, mix evenly, add the curing agent of glue must be finished within 4 hours, do not use the next day. Huizhou whole series of food-grade plastic equipment 5, pur hot melt adhesive machine in the transport and handling process, must always keep pur hot melt adhesive machine, vertical if tilted handling or transportation will damage the positioning precision of pur hot melt glue machine, may also be damaged pur hot melt adhesive machine. Mainly used for all kinds of sealing, sealing box, paper packaging, beverage bottle label, aluminum foil sealing, flexible packaging and other packaging; Ring cover paper pallet, etc, to adapt to all kinds of materials. 7. In the 50 - water-based glue drying temperature 3-60 ℃, drying time About 5 minutes. Hot melt pressure sensitive adhesive as a result of not using solvents, won't produce environmental pollution, high production efficiency, in today's rising to the call for energy saving and eliminate environmental pollution of the society, the importance of this kind of pressure sensitive adhesive also is increasing day by day. 8. Water-based glue cannot add oil curing agent, otherwise easy to cause death glue or glue agglomerate, cannot use. Huizhou 1 whole series of food-grade plastic equipment. The selection of hot melt adhesive: although some hot melt adhesive at the time of operation will be some smell, but is completely disappeared after curing, so the hot melt adhesive is safe, can be used in electrical parts of adhesive. Prolong the service life of the glue guns pet-name ruby bowl for the failure of the death of glue, glue glue should be cleaned in time, to drop into the special dumpster. The APU adhesive non-toxic pollution-free, high molecular weight so that it can form good performance of the adhesive film, it has good low temperature resistance, good flexibility, adhesive ability and the advantages of wide range of physical properties of the film can be adjusted; Flexible chain, has in its molecular structure shows good impact resistance, fatigue resistance, low temperature resistance, also has the design, the performance of rubber from the flexible and rigid arbitrary adjustable, can meet the demand of adhesion between different materials; At present, the synthesis of waterborne polyurethane adhesive has been relatively mature, basically has the following several ways: attending the surplus glue, glue bowl don't fall back to the packing barrels, so as to avoid pollution of the glue glue in the bucket. 9. To thin and uniform, water-based glue coating is too thick, after drying, can clearly see the underlying material, if see is the white layer and the brush glue is too thick. But high dosage of emulsifier and will reduce the resistance to water of pressure sensitive adhesive and sizing the bubble too much, influence the construction performance. Pu polyurethane including pressure sensitive adhesive and PUR water-borne pressure sensitive adhesive glue, hot melt pressure sensitive adhesive, is a kind of pressure sensitive adhesive, mainly composed of synthetic rubber and resin and rubber oil mixture heating molten state and then coated on cotton paper, cloth or plastic film, such as base material and made a new type of adhesive tape, on the advantages of low cost is its defects is affected by temperature is obvious adhesive.
