Ningxia how Germany pressure sensitive adhesive development direction about pressure sensitive adhesive ningxia Germany editor butyl acrylate: molecular formula: C7H12O2; CH2CHCOO( CH2) 3 ch3, molecular weight: 128. 17 colorless liquid. Vapor pressure: 1. 33个kpa / 35。 5℃; Flash point 37 ℃; Melting point - 64. 6℃; The boiling point of 145. 7℃; Solubility: insoluble in water, but soluble in ethanol, ethyl ether; Density, relative density ( Water = 1) 0. 89; Relative density ( Air = 1) 4. 42. Stability: stable. Tag ( Flammable liquids) ; Main application: used as intermediates in organic synthesis, adhesive, emulsifier. Main features editor actually hot melt adhesive machine is a kind of relatively simple devices. Host work 'content' is the hot melt adhesive melt, and then through the pressure type, delivery to lose hose or directly spray adhesive for spraying, compound, and so on. 1. Non-toxic, no smell, high transparency, no yellowing; About pressure sensitive adhesive ningxia Germany use glue, please do not add water to glue, otherwise it will affect the work of bonding strength to maintain good health, please do not mix with other products, not finished product should be kept sealed. 2. Soft, good elasticity, resistance to kink deformation; Using high temperature pur polyurethane hot melt adhesive, and really pay attention to the following items: adhesive solution viscosity ( Consistency) Appropriate adjustments can be made according to the user's requirements, freeze protection should be paid attention to the health and safety, under 0 ℃ after long time storage would destroy the performance features use machine set clean water, improve the production environment, eliminate electrostatic fire accident oily products combined with process, to ensure production personnel health viscosity 15 ~ 30 s work to maintain good health always stored in shady and cool place, avoid direct sunlight, keep temperature is 5 ~ 40 ℃ type editor by copolymerization can be the introduction of polar groups, so general adhesive force is larger. 3. No crack, long service life, cold resistant high temperature; Ningxia how Germany pressure sensitive adhesive pressure sensitive adhesive in wound treatment, bonding devices ( Such as ecg electrodes, electroencephalogram (eeg) electrodes and percutaneous electrical stimulator, etc. ) Equipment and products to physical ( Such as colon and ileal dissection device, tracheostomy tube and electricity open surgery surgery with ground mat, etc. ) , transdermal drug release patch, all kinds of labels, binder, tape is widely used, and many other aspects. A lot of customers on the hot melt adhesive machine working principle is not clear, there will be various aspects. A, hot melt adhesive can condense into a solid, the high temperature of liquid condenses into solid state even in a period of time, still with a high temperature, once touch a person's skin, can cause serious injury. 4. Have a higher resistance to tear strength and superior electrical properties; About pressure sensitive adhesive ningxia Germany 7, long time not to use pur polyurethane hot melt adhesive machine, pur polyurethane hot melt adhesive machine heating pressure plate on the circumference of a circle should be sealed with silicone oil, plastic barrels in pur hot melt adhesive performance. How about German pressure sensitive adhesive [in ningxia 3] High peel strength, with ptfe content than ordinary PET aluminum plating film adhesive save about 30%, effectively reduce the cost. Introducing polar group in molecular OH, COOH) that produce hydrogen bonding between molecules, and slightly crosslinked network structure, make the copolymer molecular weight distribution is more wide, and broad molecular weight distribution of copolymer adhesive easier pressure sensitive adhesive between the three performance good unity, the above experiments also proves this point.
