Putian fule how how putian fule binders with strengthen fire engineering plastics additives: halogen and non halogen (
In addition to the general EVA, TPR, hot melt adhesive, enterprises should also focus on research and development of the current western has a large number of applications and application potential of some advanced hot melt adhesive products, including: reactive hot melt adhesive, water dispersible hot melt adhesive, high-grade PA hot-melt line colloidal particles as well as the high strength hot melt pressure sensitive adhesive and so on.
At the same time, the relevant domestic raw materials manufacturers should also recognize the development potential of the hot melt adhesive industry, increase the localization rate of raw materials, reduce the loss of foreign exchange caused by a large number of imported raw materials.
6 water-based adhesive
and solvent-based adhesive glue brush should use different cleaning fluid immersion;
Hard monomers such as methyl methacrylate, these homopolymer Tg is higher, can enhance the cohesion strength of pressure sensitive adhesive, with the increase of the hard monomers, the viscosity increase of the pressure sensitive adhesive peel strength increases, the early viscous force will be reduced.
Kinds of oily coating adhesive is oily solvent (
Toluene, DMF, butanone, etc. )
As a solvent, dissolve or polyurethane acrylate.
Fabric with hot melt adhesive application field of hot melt adhesive 2, can also be observed in appearance, if the hot melt adhesive glue type, do manual work is coarser, then the quality.
Mainly used for production, such as shape, shoes, hats.
Use the glue of garment not only has a crisp, plentiful full appearance quality, and the nature of the ground after washing, without pressing can wear characteristics.
Use the rubber shoes, caps lightsome breathe freely, keep good type, especially for shoemaking industry, also has comfortable, reduce the advantages of shoe smelly.
Functional monomer is acrylic acid, acrylamide, maleic anhydride monomer, such as they join the introduction of polar groups in the middle of the copolymer, the electronic effect of polar group enhanced the copolymer and the polarity by bonding surface bonding of sex.
Appearance: white or light yellow granular or powder.
Putian fule adhesive overview how to use TPU plastic raw materials and definition: the definition of engineering plastics is the plastic raw material can substitute for metal products, its heat resistance to at least 100 degrees, 1000 degrees, its color is very light weight, good rigidity, modification can be achieved through a variety of physical properties, general plastic raw material sources are oil and refined out of chemicals.
Does not contain benzene, benzene, xylene, butyl acetate ester, acetone and other harmful substances, for the green products, can be safely used in food, drugs, alcohol and tobacco, children's toys and other packing materials processing notice if the glue on the skin, can clean water and soap.
Melting point: 105
115 ℃ : melt index: 18
11, pur hot melt adhesive machine pressure plate in polyurethane hot melt adhesive barrels and will air out, after locking glue valve, at this time may be appropriately increased barometric pressure in the cylinder, make the job more smoothly.
Hot melt adhesive is short for hot melt adhesive, adhesive industry is an important category of solid content, no solvents, environmental non-toxic, fast curing characteristics, widely used in automatic packaging, hygiene products, labels, tape,, automotive, construction, furniture, printing and binding, footwear, clothing and other industries, usually is refers to the present solid at room temperature, when heated to a certain temperature and melt into sticky liquid, after coating, wetting is sticky material, after pressing, after cooling to room temperature, in a few seconds to complete adhesive bonding.
Defect is due to the use of the oily solvent, so environmental protection lacking a bit, especially now that oil prices, oil solvent prices soaring all the way, most of the coating glue due to the cost is too high, so use more bad of the oily solvent, leading to environmental protection is not up to standard, in addition with the national environmental standards to further improve, so for environmental requirements of the coating adhesive is higher and higher.
Putian fule adhesive is how to use 5, only qualified personnel to pur moisture reactive polyurethane hot melt adhesive machine for maintenance work.
