Guangzhou boss packaging plastic dealers guangzhou boss packaging plastic dealer antifreeze should be paid attention to if you are unwell timely medical treatment, will destroy the performance under 0 ℃ storage for a long time, many different kinds of pressure sensitive adhesive, can be classified from different angles. 6 does note glue can also lead to immediately after pressing glue, especially larger rebound parts; ( 3] High peel strength, with ptfe content than ordinary PET aluminum plating film adhesive save about 30%, effectively reduce the cost. And copper and other metal heat conduction and local heating. 7 after pressing shoes again in a short period of time to put in the oven baked does also leads to glue; Because of the solute ( Hot melt glue) Different kinds of solvent hot melt adhesive can be made of a variety of utility. Today hardener added amount is accurate right amount, will affect the early stages of the water-based glue then force and heat resistance; 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. The way such as mixing, grafting of existing varieties were modified to improve the performance of hot melt adhesive. Pet-name ruby water-based adhesive and curing agent itself resistance to yellowing effect is very good, use water-based glue then the yellowing of shoes with other factors, such as agents, UV irradiation and so on. Adhesives are used in large equipment, such as generator, transformer and other high temperature operation of equipment, and must be under the bad environment and high shrinkage 20 ~ 40 years of equipment operation. Waterborne polyurethane ( APU) Adhesive APU is water instead of organic solvent as a new type of polyurethane dispersion medium system, also known as polyurethane or water-based polyurethane water dispersion of polyurethane, river systems. Waterborne polyurethane with water as solvent, no pollution, safe and reliable, excellent mechanical properties, good compatibility, easy modification. Guangzhou boss packaging development direction editing butyl acrylate adhesive distributor: 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. Used by the tool before drying of glue can be used warm water to clean. 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: guangzhou boss packaging adhesive distributors use glue, please do not add water to glue, otherwise it will affect the work of bonding strength to maintain good health habits, please do not mix with other products, not finished product should be kept sealed. ( 2] In many products, such as thermal transfer printing, sealing liquid crystal materials, wallpaper anti-counterfeiting grade, calligraphy and painting paper, computer printing, food, wire and cable production date type code is the performance of the application of hot melt adhesive, but cannot use the existing granule or powder form, not in a suitable solvent is made under the existence of liquid, the coating on a substrate, thin and uniform film, may be used in process after the production. Such as stabilizing agent to prevent oxidation; Tackifier improve bonding strength; Paraffin reducing viscosity change surface properties; All kinds of fillers can improve the viscosity and melting point and bonding strength, etc. Guangzhou boss packaging adhesive distributors 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. To study various varieties, dosage, chelating agent and formula optimization to meet different needs.
