How in yueyang yueyang henkel glue henkel glue is how to use polymerization reaction to obtain high polymer resin.
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.
Its advantage is good film forming, good color fastness, pu can stick hot glue, is the current commonly used coating glue.
Kinds of 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, cause the 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.
Fabric with hot melt adhesive 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, consists of main resin (
, viscosity resin, thinner or softening oil, antioxidant and other raw materials, according to a certain production process, heat melt, fully mixing, forming, cooling preparation.
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.
The use of hot melt adhesive technical indicators are as follows: used tools before drying of glue can be used warm water to clean.
Hot melt adhesive application fields of 2, can also be observed in appearance, if the hot melt adhesive glue type, do manual work is coarser, then the quality.
Appearance: white or light yellow granular or powder.
Yueyang henkel glue how with melting point: 105 -
115 ℃ : melt index: 18
If you are unwell seek immediate attention should be paid to prevent frostbite, under 0 ℃ storage for a long time can damage performance in 1 - after the product use glue
3 minutes can be repositioned, and maintain a good viscosity PH 7.
0 ~ 9.
0 in use process should be tightly covered at any time, in case the glue liquid crust, do not entry, can not let the child contact (
Pressure sensitive adhesive main body whether polymer crosslinked nCH2CHCOO (
N - three group of pressure sensitive adhesive test time is respectively: 21 h, h, 33 h.
Is the use of hot melt glue by heating the hot melt adhesive, hot melt adhesive machine melt glue after become a kind of liquid, by hot melt adhesive machine hot melt rubber hose and hot melt glue gun, to be adhesive surfaces, hot melt adhesive cooling after completed the glue.
Yueyang henkel glue refers to how to use the function monomer acrylic acid, acrylamide, maleic anhydride, such as monomer, they join the introduction of polar groups in the middle of the copolymer, the electronic effect of polar group enhanced the copolymer is bonded with polarity surface bonding of sex.
