Luoyang boss packaging plastic dealers luoyang boss packaging plastic dealer technical indicators PH 6. 5 to 7. 5 if the glue on the skin, can clean water and soap. Hot melt adhesive stick to white opaque ( Strong type) , non-toxic, easy operation, continuous use without carbonization phenomenon have fast adhesion, high strength, ageing resistance, non-toxic, good thermal stability, film toughness, etc. 。 Rods, granular shape. Low temperature hot melt adhesive suitable for hot melt glue gun, machine, used for bonding wood, paper products, fiber products, leather, metal, plastic, especially suitable for export and cold area, using the low temperature region, high adhesion, no glue falling, no crack belongs to high-grade hot melt adhesive products, non-toxic, conform to the requirements of environmental protection. Moderate hardness, better toughness, medium liquid, adhesive force is strong, easy to operate. Development direction editing 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. In fact, hot melt adhesive machine is a kind of simple equipment. 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. Food with silica gel is made from silicate polycondensation of inorganic polymer gel material, ingredient is SiO2 · nH2O, its content is over 98%, avirulent insipidity, stable chemical performance, under the normal except hydrofluoric acid and caustic, not any response from the acid and alkali salt. Since it is a kind of colloid structure, so lots of pores and large specific surface area. Below good prosperous for you to explain the hot melt glue machine, the working principle of the host: (1) common material: PU, TPU, rubber, EVA, nylon, leather, artificial leather, you can use water-based glue; (5) recipients, according to the principle of first in first out to ensure freshness. Edible silica gel pore size of about 8 - 10 nm, specific surface area, 300 - 500 m2 / g, and surface water, the water has very strong absorption ability, under the condition of high humidity the water absorbing capacity can amount to 80% of its weight The above. So the food grade silica gel can be used as food, external use of desiccant. Due to consumption of silica gel is a refined and after sterilization, can be directly when mixed with food according to the requirement and guarantees the drying of food and food to eat together, but without any poison to the human body. Main features editor but it wasn't, hot melt adhesive film is divided into high temperature hot melt adhesive film, and in accordance with the low melting point hot melt adhesive film at low temperature. 1. Non-toxic, no smell, high transparency, no yellowing; Due to consumption of silica gel is a refined and after sterilization, can be directly when mixed with food according to the requirement and guarantees the drying of food and food to eat together, but without any poison to the human body. 2. Soft, good elasticity, resistance to kink deformation; Luoyang 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. A lot of customers on the hot melt adhesive machine working principle is not clear, there will be various aspects. 3. No crack, long service life, cold resistant high temperature; Edible silica gel pore size of about 8 - 10 nm, specific surface area, 300 - 500 m2 / g, and surface water, the water has very strong absorption ability, under the condition of high humidity the water absorbing capacity can amount to 80% of its weight The above. Luoyang boss packaging adhesive distributors timely if you are unwell should pay attention to prevent frostbite, will destroy the performance under 0 ℃ storage for a long time, many different kinds of pressure sensitive adhesive, can be classified from different angles. 1) Packaging good performance, good quality 5 hot melt adhesive with heat resistance performance, can put the hot melt adhesive in zero or more than 40 degrees respectively environment for testing, if there are brittle, soft gelatin said quality is bad now.
