Weihai weihai fule hot melt adhesive price fule price of hot melt adhesive ( 1) In the structure of polyurethane resin part introduce hydrophilic group, the emulsification. Using high temperature pur polyurethane hot melt adhesive, and really pay attention to the following items: car interior environment, the indoor environment, people more and more can't put up with irritating car brands made the car interior environment standard, standard for VOC. EVA hot melt adhesive is a kind of without solvent, excluding water solid meltability polymer; It is solid at room temperature, heat can melt to a certain temperature to flow, and has a certain viscosity liquid. 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. Weihai fule price of hot melt adhesive is used to make their own DIY design of glue guns and decoration are very different, DIY designer generally not long time use, recommend the use of glue guns for DIY friends together to design good work first and then glue glue gun. EVA hot melt adhesive after melting, the pale brown or white. B, moisture near the pur reactive polyurethane hot melt adhesive machine working or hold pur hot melt adhesive glue barrel, be sure to pay attention to whether or not they wear safety work clothes, gloves and goggles. EVA hot melt adhesive by basic resin, tackifier and viscosity regulator and antioxidant components, etc. 2. Heating cleaning solvents, automotive interiors industry: car is the second largest industry, is a big industry, annual production of 22 million cars by 2014 above, China is power from the car to the car power shift. Application of construction industry on the adhesive assembly are: (1) day and night temperature difference is big, strong radiation, glue must withstand harsh environment. A, using solvent cleaning heating with viscose element, never use the fireworks or no temperature control of heating equipment cleaning, general pur moisture reactive polyurethane hot melt adhesive machine can't operate 280 degrees when cleaning and maintenance. Book binding with hot melt adhesive film is mainly divided into two major categories of thermoplastic and thermosetting, mainly used in electronic products, nameplate, plastic, hardware, mobile phone window frame and the front cover of the adhesive; Even in the uneven surface of adhesive also can obtain good effect. B, do not use for paint solvent cleaning with viscose element, because this kind of high volatile solvents, easy combustion and explosion, and can produce poisonous gas at high temperatures, and easily damaged pur hot melt adhesive machine heating the teflon coating on the pressure plate. Weihai fule prices five hot-melt adhesive, printing ink, glue viscosity change its relationship with strong reading ( 4) Grafting modification are just the right amount of styrene monomer are added into the polyurethane emulsion, made by in-situ poly polyurethane grafted styrene emulsion, improves the adhesion and water resistance. C, before using cleaning solvents, must check whether indoor air liquidity is good, avoid to use open flame, not under the environment of air does not flow cleaning pur hot melt adhesive machine. The current construction of adhesive there are two main problems: one is adhesive when a lack of proper temperature control; Second, no suitable process equipment, therefore, still need to adopt mechanical reinforcement. Weihai fule price of hot melt adhesive
is frequently used by people in daily life since it can improve chemical factory and chemical factory.
