Nanchong boss how much packing how much is the boss in nanchong city packaging adhesive 10, when pur hot melt adhesive machine heating platen press into the new polyurethane plastic barrels, should open the glue valve, complete discharge residual air in the plastic bucket, and will take the air bubbles pur hot melt adhesive ruled out clean, avoid polyurethane hot melt adhesive with air into the pump body and the hot melt adhesive machine in the throat. Fourth, resistance to temperature. Hot melt adhesive is more sensitive to temperature. The temperature reached a certain degree, hot melt adhesive began to soften, below a certain temperature, hot melt adhesive will become fragile, so choose hot melt adhesive must fully consider the product's environmental temperature change. 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. Five, sticky. Hot melt adhesive viscosity points late early viscosity and viscosity. Only late early viscosity and viscosity is consistent, can make the hot melt adhesive and then remained stable. In the process of production of hot melt adhesive, shall guarantee that the oxygen resistance, brine resistance, resistance to acid, alkali and a plastic. Being the different material, and then play by hot melt adhesive viscosity is also different, therefore, should choose according to different material different hot melt adhesive. Nanchong boss how much packaging adhesive its advantage is good film forming, good color fastness, PU can stick hot glue, is the current commonly used coating glue. Modified varieties suitable for on-line peel lee, without thermalization PH 6. 0 ~ 7. 0 work to maintain good health always stored in shady and cool place, avoid direct sunlight, keep temperature is 5 ~ 40 ℃ dry after printing water-based laminating adhesive edit operation performance is good, easy to besmear to brush, easy to clean, wet cloth to wipe away dirt viscosity of 10000 ~ 300000 mpa. S if the glue on the skin, can clean water and soap. (4) from the cleaning fluid plastic brush, must use clean cloth to wipe dry rear can be used to besmear to brush glue; Oily coating adhesive is oily solvent ( Toluene, DMF, butanone, etc. ) As a solvent, dissolve or polyurethane acrylate. The way such as mixing, grafting of existing varieties were modified to improve the performance of hot melt adhesive. 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. To study various varieties, dosage, chelating agent and formula optimization to meet different needs. ( 2] According to the provisions of GB/T 4851. 2, hot melt adhesive concept: water-based coating glue with water as solvent or polyurethane acrylate resin through specialized emulsification equipment, emulsion. New product development of nanchong boss how much packaging glue defect is poor film-forming, washing fastness, pu can't stick hot glue. If you are unwell seek immediate emulsion type and solvent type and hot melt pressure sensitive adhesive. Hot melt adhesive and curing functional hot melt adhesive are two major types of new product on the market. The former main characteristic is that improve the hot melt adhesive high temperature resistant characteristics, improve the softening point to more than 120 ℃, thus expanding the scope of its use; Functional hot melt adhesive is for a particular occasion, can realize specific functions to meet the needs of all aspects. Such as water soluble or decentralized hot melt adhesive, hot melt sealant, hot melt pressure sensitive adhesive and so on. Below is the hot melt sealant. It is a kind of polyisobutylene rubber as basic material of one-component, solvent free, not out of the fog, sulfide, has a permanent plastic insulating glass sealant. Hot melt butyl sealant in relatively wide temperature range its plasticity and sealing, and the surface cracks, the same hard. It on the glass, aluminum alloy, galvanized steel, stainless steel and other materials have good adhesive properties. Due to its extremely low water vapor transmittance, it can form a with elastic sealant excellent resistance to moisture system. Characteristics: good sealing effect, easy quality assurance; Without curing period, save area; Is environmental protection product, the use of no waste, clean environment; Save time, raw materials, personnel, reduce the production cost. Now there are a lot of coating is done with water soluble glue, such as general water soluble pa, water soluble pu and leather adhesive, oil wax feeling, the feeling of color paste and other functional material. Nanchong boss how much packaging adhesive used tools before drying of glue can be used warm water to clean. Soft monomer is to provide the pressure sensitive performance of important monomer of the copolymer in the proportion is big, such as 2 - butyl acrylate and acrylic acid Ethyl ethyl ester is, can account for 85% of the total monomer mix.
